The Path between Personality, Self-Efficacy, and Shopping Regarding Games Apps

The smartphone has made gaming more accessible and desirable for a wider market than ever before. Game apps are one of the most consumed and fastest growing products in the world today. Yet, few studies have thus far explored the implications of games apps consumption from a consumer perspective, addressing the transfer of abilities from one technological field to another. The main purpose of this paper is threefold: to ascertain the role of personality as a determinant of self-efficacy, to establish whether there is a transfer process from selfefficacy in video gaming with apps to online shopping and to analyze the impact of self-efficacy on the online purchase of game-related products. Results show that neuroticism, extraversion, and agreeableness determine the gaming self-efficacy that is transferred to online shopping self-efficacy and finally to the online purchase of game-related products. These insights provide interesting managerial implications that could affect video game marketing.


Introduction
The video game industry has become a major contributor to the global entertainment economy, moving quickly into digital contexts. Yet research on the issue remains limited [65], [51]. Indeed, the video game is a product that generates an important volume of business worldwide. For several years now, the video game industry has been generating more economic activity than other cultural and creative industries (such as, performing arts market, architectural market, design industry, broadcasting industry, book market, press market, art market, film industry, advertising market or music industry) and continues to grow exponentially due to its widespread acceptance [41], [72], [74]. Specifically, there are more than 2.4 billion gamers worldwide, and the value of the global gaming (throughout the paper, gaming refers to playing video games) market stands at 231.6 billion dollars [71]. The mobile game market represents 47% of the game industry's total sales, surpassing the console (28%) and the computer (25%) [71]. Due to the massive increase in personal digital distribution, the scope of video games is much greater than in the case of offline distribution.
One key factor influencing the growth of the video game industry is increased smartphone penetration (2.5 billion smartphone users worldwide) [87], which has brought this product to a wider audience and even represents an alternative new business model [65], [98], leaving video game consoles for users who spend more time playing [39], [71].
Regarding the up-to-date top mobile game app information, the global mobile gaming app revenue will represent 74.6 billion U.S. dollars in 2020 [89]. The preferred format for European gamers is the free and freemium game (55% of video gamers have tried between two and five new games in 3 months) [40]. The freemium model (free download game but premium -money-is charged for additional features) now dominates the ecosystem of mobile games, provides 95% of its revenues and it is mainly subsidized by advertisements [40]. Each day 2500 and 236 game apps are published on the two main global platforms (Google Play and Apple App Store, respectively) but a freemium game -Clash of Clans-is the leading mobile game title worldwide (with revenue of 1.35 billion U.S. dollars) [88], [89]. However, the games that show the higher increase are eSports (26%) and virtual reality ones (259%) [39].
Every day, smartphones are being used for a growing number of activities: we phone, we chat, we browse, we read, we play, and we buy. The device's use has increased individuals' abilities and their confidence to use it for additional tasks and functions. Therefore, it may be conjectured that the abilities acquired when playing game apps with the smartphone (or tablet) may be transferred to other uses of the smartphone (or tablet), specifically, to online purchasing of game-related products. Both activities are performed through new technologies, an electronic device and a screen, and require direct interaction with users, which has a direct impact on them and their environment [22]. We can assume that the abilities and skills acquired by individuals when playing with game apps prepare them to deal with online purchase platforms such that they might perceive online shopping as easy as online playing.
These facts and issues pose some questions concerning the video game area. Is gaming behavior related to online shopping behavior? Might there be a transfer of relevant variables, such as self-efficacy, from one field of technology use (video gaming) to another (online shopping)? Does personality exert any influence on self-efficacy and such a transfer process? Bearing these questions in mind, this research pursues three goals: a) to establish whether gamer personality determines self-efficacy; b) to ascertain whether there is a transfer process between self-efficacy in video gaming and online shopping, and c) to analyze the impact of self-efficacy on the online purchase of game-related products.
As for the first objective, based on the trait-theory, we focus on personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness) as psychological factors related to the skills and abilities that use technologies either to play or to buy. Researchers have highlighted that personality is a major issue in studying human dynamics on line [56]. It is a key to brand success for [62], a key in online gambling behaviour [1], a key in the use of social networks [20] and, for [38], [97], a key in which video game to play.
As regards the second objective, and despite it being somewhat evident, the relationship between playing video games and using electronic commerce has rarely been explored. Specifically, this study deals with two prominent digital media forms in today's social environment -playing game apps and online shopping- [58]. According to the self-efficacy theory, one key factor to successfully perform both tasks is self-efficacy, that is, one's belief in one's ability to succeed in specific situations or to accomplish a task [13]. Game playing, and online shopping require a certain level of expertise, knowledge, or skills if they are to be executed successfully.
Finally, regarding the third objective and although other authors have already studied self-efficacy as a determinant of technology adoption and purchase behaviour [43], [45], [52], [91], our innovative model applied to video gaming proposes a sequence from personality to self-efficacy and to the online purchase of game-related products. By studying personality traits and self-efficacy, this work presents a more humanistic viewpoint in the analysis of consumer behavior and the adoption of new technologies and provides a distinctive approach from the more techno-centric models (i.e., the Technology Acceptance Model), as [82] also emphasize. Moreover, the possibility that there might be transferable skills between different technologies that can lead to self-efficacy with one technology being transferred to another field of technology use is yet to be addressed in the literature.
In the second section, the theoretical framework of the study is presented and, the proposed model and the hypotheses are discussed. In the third section, the methodology and results are shown. The section four, includes the discussion as well as the limitations and future research. The last section, section fifth, includes the conclusion.

Conceptual and Theoretical Background and Proposed Hypotheses
In this section, the key role of consumer personality and self-efficacy is highlighted. First, the Big Five model is used as a theoretical framework to understand video gamer personality. Second, the theory of self-efficacy is revised to understand this variable and how it derives from the five personality traits. Finally, a transference process from gaming self-efficacy to online shopping self-efficacy and purchase intention is proposed.

Consumer Personality. Big Five
The Trait Theory is the most influential school of thought in personality psychology [62]. Specifically, one of the most well-known and widely used personality models in psychology to measure the five previously mentioned personality traits is the Big Five model [20], [32], [60], [62], [81], [82]. Indeed, behaviors are better predicted using a common framework such as the Big Five [83]. Recently evidence [73] reveals that personality traits could be reliable sources to describe consumers' behaviors.
Following [32], [38], [62], [67], [82], personality traits are the extent to which consumers appraise themselves regarding five dimensions: (1) conscientiousness assesses one's degree of organization, persistence, and motivation in goaldirected behaviour; (2) neuroticism assesses an individual prone to psychological distress, unrealistic ideas, excessive cravings or urges, and maladaptive coping responses; (3) extraversion assesses an individual's quantity and intensity of interpersonal interaction and activity level; (4) agreeableness assesses an individual's quality of interpersonal orientation along a continuum from compassion to antagonism in thoughts, feelings, and actions; and (5) openness assesses an individual's proactive seeking and appreciation of experience for its sake, toleration for, and exploration of the unfamiliar.
In the context of video games and online games, personality traits have been related to the fact of playing or not, the style of playing, addiction to video games, and the motivations and benefits derived from playing (see Table 1). However, the link between the Big Five traits and self-efficacy playing has yet to be studied.

Self-Efficacy Role
The theory of self-efficacy lies at the heart of Bandura's Social Cognitive Theory [10]. Self-efficacy refers to peoples' judgment of their ability to organize and execute courses of action required to attain designated types of performance [12], [35]. It is domain specific and strongly tied to the behavior of interest. Self-efficacy is concerned not only with the skills one has but also with the confidence with which one uses those skills [14], [35], [91].
As with self-confidence or self-control [64], self-efficacy is an individual resource, according to psychology literature. However, unlike other self-traits such as self-esteem, self-efficacy refers to individuals' self-assessment of their capacity to accomplish a given task and achieve a particular goal [13], [58]. Self-efficacy is a broader engagement of inner resources that encompasses feelings, cognitions, and behaviors [91].
In this work, we consider gaming self-efficacy as individuals' self-assessment of their capacity to solve the challenges posed in a game and to become skilled in a game app. In the context of video games, we have only found the study by [57], which specifically uses video gaming self-efficacy and computer gaming self-efficacy. Similarly, online shopping self-efficacy refers to individuals' self-confidence when searching for and acquiring products and services in online stores [36]. Following several authors, self-efficacy is specifically related to different contexts and concepts, giving rise to various kinds of self-efficacy apart from general self-efficacy [29], [52], [57]. As an example, [43] distinguished between general Internet self-efficacy and specific www self-efficacy as different concepts.
The predictive capability of self-efficacy is strongest and most accurate when determined by specific domain-linked measures rather than by general measures [82]. In this line, specific self-efficacy is one of the factors that proves a key driver vis-à-vis understanding individual behavior and adoption of new technologies [43], [45], [52], [61], [82]. For instance, [64] emphasize the importance of possessing expertise and self-control in order to perform shopping tasks successfully. While players who value video game success as part of their identity may reap benefits from video game playing, those who do not value such success may experience more harmful effects [92].

Personality-Self-Efficacy Link
High self-efficacy is attributed to individuals' beliefs that they can manage and solve the problems at hand more successfully [91]. However, self-efficacy can be influenced by personality. Individuals' personality can affect their level of self-efficacy [13]. Nevertheless, few studies have related personality traits with consumer self-efficacy [52], [58], [61], [77], [91]. Some studies have explored personality traits as drivers of gamer behavior [23], [30], [49], [85], although to the best of our knowledge, none have thus far related personality to self-efficacy in a video gaming context.
As regards conscientiousness, [77], [82] found that it is positively associated with task fulfillment and job performance and that it influences self-efficacy. In the context of gaming, it can be assumed that game players must be persistent if they are to achieve game goals and be successful. In other words, persistence and motivation allow players to achieve self-efficacy and become skilled players.
As for neuroticism, [82] find that neuroticism negatively influences self-efficacy. Individuals' psychological distress may limit their ability to become skilled and thus obtain the expected achievements in a game. Indeed, one of the harmful effects of playing video games is stress and anxiety [69].
As for extraversion, in gamer behavior [26] argue that social influence, which explains how other people's attitudes or opinions may affect an individual's decision making, is a determining factor in social games. Extraversion positively influences self-efficacy [82]. Interacting with other people, coupled with a tendency to be sociable, may increase their knowledge of the game and their abilities and skills when playing it, as suggested by [100].
Results concerning the effects of agreeableness on self-efficacy are mixed. While [62] finds a significant relationship between agreeableness and brand loyalty in the case of video games, [60] observe a negative effect of agreeableness and Internet usage, and [82] find that agreeableness negatively influences self-efficacy. These authors argue that there is no reason to propose a positive relationship between agreeableness and self-efficacy since the former is related to higher computer anxiety and less use of mobile phones. In [55], agreeableness was not significantly related to selfefficacy.
Finally, individuals displaying openness are more willing to try something new and also possess good imagination. An open mind is usually an advantage when solving problems at work and in life; consequently, open-minded individuals would also have a positive evaluation of their efficacy [77]. Openness increases loyalty to video games [62] and, in the same line, [66] show that openness relates to brand loyalty to products which have a hedonic value. Also, [82] find a positive influence of openness on self-efficacy. In the context of gaming, players' openness involves searching for new experiences as well as imaginative and innovative games. Eventually, the search for new experiences might increase their abilities in the game.
Gamers are thus expected to display greater self-efficacy if they are organized and persistent (conscientious); not worried, nervous and emotionally stable (not neurotic); sociable, optimistic and talkative (extrovert); unforgiving, cold and skeptical (not agreeable) and curious, creative and imaginative (open). Following the previous reasoning, the hypotheses proposed reflect the effect of personality traits on gaming self-efficacy.

Proposed Transfer between Gaming Self-Efficacy and Online Shopping Self-Efficacy
As [45] affirms, Internet has potentially and irrevocably impacted on the way business is conducted and has redefined the parameters of business in general. Indeed, the Internet has grown to become one of the leading sales channels today, with game apps being no exception [65]. Prior research provides evidence about the link between mobile gaming and online shopping behavior [11]. [93]'s study has found that richer online formats and recommendations throughout video games enhance consumers' perceptions about experience products and positively affect consumers' intentions to purchase products. Furthermore, [44] found that app-based gaming has created complex models to generate purchase (in and out the game). Models that comprises explicit exchange of money for digital items within each game or economic systems based on virtual assets (e.g., Worldwide Asset eXchange and OPSkins market) and no explicit -nor direct-purchase related to the game (i.e., through branding freemium games or ads). Recent data [34], [89] suggest that video gamers conduct in-game purchases, such as upgrades, additional lives, currency, personalized avatars, an ad-free experience, unrestricted playing time or special items (i.e., famous football players' avatars or skins that modifies the appearance of a character or item), and consumer spending on in-game purchases will grow until 32 billion in 2020. In fact, 4% of global iOS device users and 3% of Android users are making in-game purchases per month and [89].
In this context, online shoppers must demonstrate adequate self-efficacy as a precedent of Internet shopping and when buying game-related products. As [52] point out, Internet self-efficacy is not as important in offline contexts as in online contexts because consumers learn how to make an offline purchase at an early stage. In fact, consumers exhibiting low self-efficacy are uncertain and feel uncomfortable with Internet shopping [45]. Internet or computer selfefficacy is felt to be one of the best predictors of online shopping [43], [59].
To the best of our knowledge, the only study to specifically use self-efficacy during online shopping (online shopping self-efficacy as a concept) is [36]. Online shopping self-efficacy, or the belief in one's ability to organize and perform the Internet actions required to produce given attainments, is a potentially important factor when buying online.
Following Rogers' Theory of Innovation Diffusion, people are more likely to adopt an innovation they are comfortable with and that is compatible with other technologies they already use [79]. Following [13], [52], perceived self-efficacy will tend to transfer across two tasks within the same domain based on the degree of similarity between the qualitative features of the two tasks and the skill they require. Recently, [100] found evidence of transfer of technological game knowledge between different individuals interacting in the same group.
As [43] suggests, when users decide to adopt one activity they tend to adopt another similar one. According to his study, people are more likely to adopt information technologies that are functionally compatible with those previously adopted. More specifically, [43] proposes that prior use of the telephone is positively related to adopting online shopping and that Internet self-efficacy has a positive relationship with the adoption of online shopping. Following his arguments, and applying them to our research context, when playing with game apps and when purchasing online game-related products, when users complete transactions over the Internet they must transfer private information over the network creating a similar mode of action between the two contexts. Moreover, gaming and online shopping require a similar amount of skill and are contingent on the same premise (fulfilling users' goals successfully and facing the challenge of winning the game or receiving high-quality game-related products). These arguments are coherent with what [79] calls technological clustering, which occurs when adopters of a given innovation perceive another new idea as being closely related. Therefore, when consumers exhibit self-efficacy playing a video game, they will probably display this ability when purchasing related products. Therefore, we propose that video gamers acquire several skills when playing, the fact that allow them to feel more self-confident and effective when using online shopping platforms to buy games or accessories.
This self-efficacy transfer argument also fits in with the evidence regarding the benefits of video games as teaching tools [25], [100]: they are used for military training, for teaching in schools, or for teaching perceptual skills (such as attending to more visual cues). "By playing video games the individuals learn scripts, organized sets of knowledge that define situations and guide behaviors" [25] (p. 368) and how to solve problems. They conclude that video games can teach, regardless of their content and regardless of the gamer's intended use.
Thus, the following hypothesis tests self-efficacy transfer from one technological field (video gaming) to another (online shopping). Summing up, this hypothesis contains a novel contribution to the literature in this study and involves personality traits determining gamer self-efficacy and these skills being transmitted to other activities, specifically to online shopping.
H6: Gaming self-efficacy positively influences the self-efficacy of online purchases of game-related products.

The Influence of Self-Efficacy on the Intention to Purchase Online
One of the main goals pursued by most companies is to attract and retain customers, which is also applicable to online game-related shopping. Purchase intention is defined as the players' willingness to purchase virtual items for use in the mobile game [8]. Players may need to buy additional complements and items if they want to progress quickly in the game (extra time, lives, moves, virtual items to access higher levels, etc.). In this sense, one way to achieve such a goal is self-efficacy. In fact, some authors have emphasized the importance of self-efficacy in behavior and adoption [29], [36], [82]. Internet and computer self-efficacy are two of the best predictors of online shopping [52], [59], [91]. [43] posits that self-efficacy influences overall adoption of electronic shopping. Consumers engaged in Internet shopping transactions should demonstrate adequate self-efficacy which precedes perceptions strongly associated with Internet shopping [45]. In line with these findings and suggestions, the final hypothesis reflects the idea that if gamers display self-efficacy when purchasing online game-related products, they will later acquire more games and accessories online.
H7: Online shopping self-efficacy positively influences the intention to purchase game-related products online.

Empirical Study
In this section, the sampling process and measurement scales are described. Besides, the analyses made, the results obtained and the supported hypotheses are explained.

Sampling and Measures
Information was collected from a sample of 366 Spanish game app players. The questionnaire was handed out personally to players of video games who have bought online video game related products/services (e.g., extras, premium game versions, music or games), and regarding the last app game played. On average 4.5 gamers in the sample play the same game. To collect data, we used snowball sampling. We contacted a group of players each of whom was asked to answer a questionnaire and to collect two additional questionnaires from other players they knew. Participants ranged in age from 18 to 65 (M=23, SD=7.81) and dedicated an average of 4.4 hours per week to playing game apps. The sample shows certain similarities with the average Spanish video game player. 65% is young (between 15 and 24 years old) and play an average of 6.6 hours per week [3]. Last available data from the gaming study show that 57.6% of females prefer to play with mobile game apps while 61.1% of males prefer consoles [4]. Gamer categories in Spain [54] include 56% of males, 21% between 6 and 24 years old; 35% of males between 25and 64-years old play with games apps; 44% of females are gamers, 19% aged between 6 and 24 years old and 25% of females aged between 25 and 64 years old play game apps. Table 2 provides further details about the sample profile. five orthogonal factors (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness), one for each personality trait [7], [42]. In [48], it is suggested to include all the dimensions, since most individual differences in human personality can be classified into these five broad personality domains. The selection of specific subscales from the index to fit the research purpose was proposed by [7], [38], [47]. They have been effectively operationalized as reflective scales in recent studies on gaming and mobile purchase behavior [18], [42], [82].
Self-efficacy scales were likewise taken from prior literature so as to improve their validity content. We use the scales proposed in [13], [28], [35] to measure self-efficacy. Prior studies have tested the unidimensionality and validity of the reflective self-efficacy scale across several contexts, including mobile purchase and online behavior [82], [84]. In line with the recommendations of [21], selected self-efficacy items are the ones that best capture individual beliefs regarding specific tasks under research. To measure purchase intention, we employed a three-item reflective scale that refer to the individuals' intention to invest additional money in the game app [8] (for item details see Table 3).
The translation and reverse translation processes were completed by two native-English-speaking researchers to guarantee the readability and clarity of the survey [24], [70]. Afterward, a pilot test with 15 players was conducted to pinpoint and correct shortcomings in the questionnaire. Five-point Likert scales were used, ranging from strongly disagree (1) to strongly agree (5).

Analysis and Results
Data analysis was conducted using LISREL 8.7. Confirmatory factor analysis (CFA) shows that all standardized loadings are significant at .001. After re-specification (items suppressed due to a low R 2 ), results indicate that the measurement model provided a good fit to the data since all the fit indices met the threshold criteria recommended [5], [50]. Specifically, the model estimation showed a χ 2 (468) of 837.78 (p=.00), a Comparative Fit Index (CFI) of .93, a Goodness of Fit Index (GFI) of .90, and a Root Mean Square Error of Approximation (RMSEA) of .047. Likewise, all Cronbach alpha (α) values are greater than or equal to .7, except in the cases of agreeableness and extraversion, which were slightly below .7. However, since all of the remaining coefficients in our study fulfill the requirement, this might be due to the number of items comprising those constructs [47]. Furthermore, although the Cronbach alpha ( ) is the most widely used estimator of scale reliability, it is thought to underestimate reliability. A better option to test reliability is composite reliability (CR) [78]. All (CR) values exceed .7, and average variance extracted (AVE) values exceed .5 [9]. Table 3 presents elementary descriptive statistics (mean and standard deviation) for the observable variables included in the measurement model, scales validity and the significant standardized coefficients lambda (λ) of the CFA. To test discriminant validity, the Fornell-Larcker criterion says that a factor's AVE should be higher than its squared correlations with all other factors in the model. Thus, we discard discriminant validity problems [46] (Table  4).  Common method bias may exist when measures use the same method (self-report, scale type) and might yield inflated correlations between constructs. As recommended by [63], our assessment used the correlations between the Big-Five latent constructs, two self-efficacy constructs, intention to purchase, and the marker variable with a two-item measure of group norm (V44 and V45) to perform this analysis. The correlation between group norm and purchase intention was .47. Using [63] formula, the corrected values for the correlations between consciousness and group norm, we computed the Common Method Variance (CMV) adjusted correlations among the research constructs using the second lowest correlation (r=.04) as a proxy for marker variable. Table 4 shows the correlations between constructs below the diagonal and the adjusted correlations above the diagonal. We also determined the statistical significance of the adjusted correlations. All the correlations that were significant before adjustment also remained significant after adjustment. In this sense, marker-variable analysis indicated that common method bias is unlikely to affect the findings of this study. The following step in the analysis was to test the proposed hypotheses using structural equation model (SEM) analysis ( Figure 2).  All the hypotheses are supported at a confidence level of 95% except H1 and H5, which are rejected. Following prior research on self-efficacy [2], in order to ensure the validity of our results two gamers' behavioral variables (frequency of gaming with apps and frequency of online purchasing) were included in the model as control variables. Attending [19] recommendation, control variables must hold theoretically meaningful relationships with predictors and criteria. In this sense, prior research suggests that usage and purchase should be employed as dependent variables and relate to the frequency of this purchasing and gaming behavior [37]. Specifically, [2] support a bidirectional association between frequency of playing video games, self-reported problem-solving skills and gamers' behaviors (that may include online shopping related products and services). However, after controlling for these playing-related variables, no changes either in the significance or direction in the proposed relationships were detected. Table 5 presents the assessment of the overall model fit and the hypotheses supported.

Control variables
Frequency of playing with apps → Intention to purchase online .118** - In addition, the Baron and Kenny [15] approach was followed in order to test the mediation effect of shopping selfefficacy in the model. We created a model including direct as well as indirect paths [80]. In other words, this model included all the paths in our research model (Figure 1) as well as an additional direct path from gaming self-efficacy (independent variable) to purchase intention (dependent variable). To test the mediating role of shopping self-efficacy, the mediation analysis results show that gaming self-efficacy remains significantly related to purchase intention after controlling for the mediating variable (shopping self-efficacy) [(ß=.252; p<.05)], suggesting a partial mediation effect of online shopping self-efficacy.

Discussion and Implications
As [82] underline, the finding that specific personality traits significantly relate to gaming self-efficacy gives credibility to the notion that individuals may inherently apply the efficacy acquired when playing to performing other tasks related to their shopping habits in the virtual context. Extrovert gamers show high gaming self-efficacy. These results support previous literature which suggests that an extrovert individual can more easily handle work pressure such that they perceive better performance [66]. In contrast, affable gamers might lack persistence, which makes them perceive lower gaming self-efficacy. Affable people tend to avoid challenging either themselves or their established ideas [62], [82]. Affable gamers may not, therefore, display high self-efficacy and may thus seek to avoid interpersonal conflicts, preferring to cooperate with others rather than compete with them.
In a similar way, neurotic people evidence characteristics that easily result in fear, anger, loneliness and dissatisfaction with themselves. Therefore, neurotic gamers also perceive lower self-efficacy when playing game apps. This might be caused by these negative feelings which could be curtailing gamers' ability to deal with gaming problems or difficulties [55]. Openness does not significantly generate or enhance gaming self-efficacy. There is no consensus in previous literature regarding this relationship. In fact, some authors find support for a relationship between openness and selfefficacy [82] whilst others do not [55]. Moreover, and in agreement with [82], conscientiousness does not influence gaming self-efficacy. In this sense, traits such as dependability, achievement orientation, perseverance, deliberation, scrupulousness, and punctuality do not seem to be related with gaming self-efficacy. This might be because conscientiousness characteristics could prove more important in a relevant and high-involvement task such as organizing and executing courses through computers [82] or buying a house [77] than it is in leisure activities (such as gaming) or the use of social networks [20]. According to previous evidence found by [95], when the purpose is to analyze virtual consumption (such as game apps and related-gamming products), consumers are disposed to communicate their self-concept (including their personality) via the use of the products that convey desirable, and this fact facilitates consumers' purchasing behaviors' regarding products that have certain personal significance.
Finally, the evidence about the positive transfer of self-efficacy among similar technological tasks (i.e., gaming and purchase through the Internet) contributes to a better understanding of shopper behavior. It is an interesting finding since there is a gap in the literature regarding the impact of gaming on consumer behavior [27], [37]. As for gaming app use, game-related self-efficacy drives the electronic commerce of game-related products. This finding is unique and important since it supports a widely accepted belief about game effects on gamers' self-perception and purchase behavior [37]. In addition, this study offers evidence that confirms the existence of different kinds of specific self-efficacy [29], [43], [52], [57], also in a gaming context, rather than only a general self-efficacy perception. The proposed sequence reveals that gamer personality differences can influence self-efficacy in gaming and that this is transferred to another task (shopping) as gamers play.
These personality traits that influence gaming self-efficacy indirectly affect online shopping self-efficacy, thus showing a transfer of self-efficacy between different technological tasks. Also, [91] found a partial mediating effect of selfefficacy between personality traits and behavioral intentions. In this way, the study confirms previous findings concerning the influence of specific kinds of self-efficacy on online shopping intentions [43], [45].

Managerial Implications
From a managerial perspective, understanding the phenomenon of self-efficacy transfer is crucial, as media such as game apps are beginning to play a major role in marketing activities. Companies are recognizing the potential of game apps as a means of marketing products and services. In agreement with [86] and the Theory of Innovation Diffusion, the popularity of video games makes them spread through social networks, motivating players through innovative and unique designs. Since, actual digital media users' philosophy of open access implies no immediate payment in order to play video game [44], game developers ought to be aware of the alternative paths (such as micropayments or virtual assets transactions) to reach gamers' purchase intention (in order to maintain the ecosystem developed for generating revenues).
Our results reveal how gaming might have practical implications for marketing managers. If firms teach players how to play, it could indirectly promote the online purchase of related products, which also supports the effectiveness of gamification strategies. In this sense, [53] propose the use of gamification strategies to offer a good video game, with added value, thus enhancing the playing experience and entailing benefits for both game developers and players alike. Keeping in mind that central to the game model is consumer choice, players will accept better non-imposed marketing strategies. In this sense, game developers may let master players (i.e., that show high gaming efficacy) to exchange information (tips, strategies or trick) for extra features with others, making easy microtransaction process between consumers (C2C commerce inside the game).
Managers should try to develop user-friendly and easy to surf sites so as to enhance convenience and allow users to become familiar with interfaces and show self-efficacy with Internet behaviors. In [43], the aspect of equivalent skill level as analogous to Rogers' evaluation criteria of perceived complexity is studied, which predicts faster adoption when technology is easier to use. A practical guideline for gaming companies is to employ social networks to connect with their customers to ask for feedback about the perceived level of online tasks difficulty and self-efficacy perception (about gaming and purchasing).
This research denotes possibilities for interventions by consumer educators and managerial video game industry actors. For example, platforms that offer a sense of comfort and an appealing task-accomplishment orientation helps to promote self-efficacy among users [45], [94]. To that end, providing flexible learning environments, also among members of a group who play games [100], can also be useful to promote user self-efficacy and help them achieve their goals successfully. Regard this result, game firms might reward players with free items (such as new level trials in advance, outfits or skipping stages) in return for sharing their knowledge with other gamers, if they are coaching other players, they are promoting and recommending [11], [93] to consume certain games and, finally enlarging the life cycle of the games and related products.
Finally, consumers who register high emotional stability and extraversion and low agreeableness are the target audience for firms operating in the video game industry as these are the personality traits that most influence selfefficacy and, consequently, the opportunities to acquire new abilities and transfer them to online buying behavior of game-related products. As app developers employ various business models to generate income, such as pay to play games, in-app purchases during play, or in-app advertising [40], gaming companies might be able to incentive gamers with a free trial period, free virtual elements or ad-free period experience in exchange for the information regarding gamers' personality and perceived self-efficacy to segment their market.

Conclusion
In an age of intense competition such as the present, any marketing action must commence with a good knowledge of which factors impact on client (player) behavior, whose actions can be explained by personal variables and interaction processes (in this case, consumption of game apps and related online purchasing). "Converting online mobile game users' to loyal customers is a mandatory action to instil purchase intention among them" [11] p. 244. The objectives of this study were: a) to consider game player personality as a driver of gamer self-efficacy; b) to study the transfer of self-efficacy from an app gaming context to an online shopping context; c) to explore the role of self-efficacy as an antecedent of the intention to purchase game-related products online. Although there are several studies on innovation adoption [36], [61] and only a few in the case of video game adoption [97], to the best of our knowledge there are no works addressing our understanding of the self-efficacy transfer process between two technological contexts. We feel that it is imperative for both scholars and marketers alike to understand the internal factors underlying gamers' behavior and how such factors make consumers embrace the online purchase of game-related products.
The paper's contributions are as follows. Firstly, the study offers new insights into self-efficacy transfer in processes related to the use of new technologies. Little is known in the literature about the factors affecting self-efficacy since most research focuses on the impact of self-efficacy on technology adoption or acceptance [36], [82]. In fact, dispositional factors, such as personality traits, have remained largely unexplored in marketing literature. Secondly, this work evaluates the transfer process from game player behavior to online shopping intention for game-related products. As far as we are aware, only the study of [57] refers to shopping self-efficacy. In particular, the analysis establishes the existence of a process of self-efficacy transfer that ultimately leads to online purchase intention, a sequence of personality-self-efficacy-behavior which has relevant academic as well as managerial implications. Thirdly, the study focuses on a fast-growing industry, the game app industry and uses information collected from a wide sample of actual app gamers.
The results of this study show that there is only one personality trait -extraversion-which increases the perceived gaming self-efficacy while two personality traits -neuroticism and agreeableness-can reduce the perceived gaming self-efficacy. Likewise, it is remarkable that the results here imply a sequence of positive effects from gaming selfefficacy across online shopping self-efficacy until intention to purchase online. Therefore, the main managerial implication deriving from this work refers to the need for the firms to know the gamers' personality and segment the market accordingly as it affects their self-efficacy not only playing, but also shopping online.

Limitations and Further Research
The results are valid for Spain and for the video game industry and cannot, therefore, be generalized unambiguously.
The sample is composed of game app players, who display a certain level of gaming self-efficacy. It would thus be advisable to study the moderating role of playing experience and the online purchase experience. Furthermore, we use a short version of the Big-Five inventory. Future studies should use another measurement instrument such as the 60-item NEO five-factor inventory [33] and should go further about how could vary gamer's consumption behavior when playing different games apps at the same time. Other related factors such as the ease of use and purchase within each game [37] could be considered as being also of interest for marketers.
It might also prove enlightening to study the negative aspects of playing and online purchasing, such as perceived risk, social isolation or addiction, which leads to the interesting issue of self-regulation [35], [51]. It would be prudent to compare real-world activities and virtual worlds so as to ascertain whether adopting certain activities such as game app playing is a substitute for the real-world counterpart, as [43] suggests doing. In the same line, it would be interesting to compare the behavior of gamers and non-gamers [51] as well as to consider other antecedents of self-efficacy, such as emotional intelligence [91]. More research could be conducted for specific games, as there can even be a selfefficacy specific to a certain game. Finally, different genres of game apps might spark a different degree of self-efficacy transfer and personality trait influence.
