In the Text
The format which must be used to write the headings in the text is the following:
Level 1: centered heading, font size must be 10 points, bold, capital letters for the important words.
Level 2:heading aligned to the left, font size must be 10 points, bold, capital letters for the important words.
Level 3:heading of paragraph with an indentation of 0.63 cm, font size must be 10 points, bold, capital letters only for the first letter of the first word, ends with bold period. The paragraph begins after this, starting with capital letter and normal font.
Level 4:heading of the paragraph with an indentation of 0.63 cm, font size must be 10 points, bold and italic, capital letters only for the first letter of the first word, ends with bold and italic period. The paragraph begins after this, starting with capital letter and normal font.
Level 5: heading of the paragraph with an indentation of 0.63 cm, font size must be 10 points, italic, capital letters only for the first letter of the first word, ends with italic period. The paragraph begins after this, starting with capital letter and normal font.
In articles with one level the level 1 heading is used; in articles with two levels, the headings for levels 1 and 2 are used, and so on.
Example for three heading levels:
Example for four heading levels:
Example for five heading levels:
The introduction section has no heading (it is left implicit). Placing only one heading on one section must be avoided; use at least two subsection headings in a section or use none.
a) To indicate the ordering of elements in a series within a paragraph or sentence, use lowercase in parentheses. Example:
The three options of the participants were (a) working with another participant, (b) working in teams, or (c) working alone.
Within a sentence, use commas to separate three or more elements which do not have internal commas, otherwise, use semicolon.
b) To indicate the ordering of separate paragraphs, number each paragraph with an Arabic numeral, followed by a period. The second line and the following ones must be aligned at the beginning of the text of the first line. The first and last paragraphs must have a space of 3 points in relation to the text. Example:
The data was studied using the following analysis:
c) If numbering the elements may produce an unwanted order of importance of them, a bullet may be used, such as ▪. Example:
The statistical analyses were the following:
The following numbers must be written in words:
The following numbers must be written in numbers:
Use of Capital Letters and Punctuation Marks
Capital letters are used as in general English or Spanish. Nevertheless, some specifications are needed.
Use capital letters in:
Do not use capital letters in:
Use double quotation marks:
Do not use double quotation marks:
Use an em dash (or long hyphen):
Usar guión corto:
In general, italics must not be overused.
Do not use italics:
Tables must be formatted as Word tables and must be centered on the page. The font size depends on the size of the table. If it is very small, use font size 10, if it is medium, use font size 9, and if it is large, use font size 8. Use only two horizontal lines at the top (or three, according to the columns heading) and one at the bottom (simple lines of ½ point). Do not use vertical lines and limit the use of other horizontal lines to those which may be necessary in order to give greater clarity to the organization of the information.
The title of the table must be placed at the top, starting where the table begins and finishing where the table ends, leaving a simple space between the title and the table itself. The title must be written in italics (not Table X) and only the main words must start with capital letters (do not use capital letters for articles, conjunctions, or prepositions, unless they are four letters long or more).
The labels of the columns must be centered (including the label of the first column) and capital letters should be used only in the first word. The labels of the rows must be justified to the left and capital letters should be used only for the first word.
Figures with decimals must have the same number of decimals places and, if possible, no more than two (unless the information presented makes it necessary). Figures in the body of the table must be centered, keeping the alignment of the numbers towards the right. When figures contain decimals, they must be aligned at the decimal period (or the comma in Spanish), and when figures are written with comma for thousands (or period in Spanish), they must be aligned at the comma (or the period in Spanish).
The table’s notes must be placed under the corresponding table and the font used must be one point smaller than the one used in the body of the table. Notes must follow this sequence: general note, specific note, probability note.
Tables must be numbered with Arabic numerals in the order in which they are mentioned for the first time within the text. Each table must also have a brief but clear and explanatory title.
Every table must be cited in the text of the article in order to inform the reader what to look for, referring to them by their numbers. Examples: “... (see Table 1)” or “In Table 1 it can be observed that...”.
When publishing the article, tables included on separate sheets will be inserted in the text. Therefore it must be specified in the document where, approximately, each table should be inserted, in the following way:
[Insert Table 1 approximately here]
Examples of Tables
A figure is any kind of illustration other than a table. Thus, a figure can be a graphic, a photograph, a drawing, a map, or a diagram.
Number all the figures sequentially, with Arabic numerals, in the order in which they are mentioned in the text. In the same way, refer to the figures in the text by their numbers. Examples: “As it is shown on Figure 3...” or “... (see Figure 3)”. The figure must be centered on the page.
Under the figure a number must be placed (in italics) and its title (in normal font) after a period in italics and a space. Use capital letters only for the first letter of the first word and the first letter of the proper names of the title. The title should explain the figure using a brief but descriptive phrase. It is included below the figure, but without being a part of it. So, any title within the figure must be eliminated. Example:
Figure 1. Distribution of the attachment styles in the sample.
The legend explains any symbol used in the figure and must be part of it (use capital letters for the main words and 4-letter or longer words).
Immediately after the title, add any additional information which may be needed to clearly understand the figure (not as a Note). Example:
Figure1.Distribution of attachment styles in the sample. The attachment styles are: secure (S), insecure evasive (IE), insecure ambivalent (IA), and insecure disorganized (ID).
The reader should not need to refer to the text in order to understand the figure. Always explain units of measurement, symbols, and abbreviations that are not included in the legend.
Submit the figure to the Journal in the program in which it was created, so that it can be edited, if necessary.
Report of Statistical Information
Statistic symbols and parameters must be written in italics (examples: M, SD, t, p, r, F, N), except for those written in Greek (β, χ2) and non-statistical subscripts of statistical symbols (Fmax , SA + SB). Enough information must be given for the reader to fully understand the analysis performed. The information reported must allow to confirm the basic analyses and to give possible alternative explanations to the results. Therefore, in addition to the basic results associated with the null hypothesis test, further information must be given, such as the effect size, confidence interval, and other additional descriptions in order to that the reader fully comprehend the meaning of the results.
Mean and standard deviation. When a value of the mean is reported (either in the text or in parentheses), it must always be accompanied by the standard deviation. Example: The average age was 35 years (SD= 6.8).
Chi square. When Chi square results are reported, besides the value of c2, the degrees of freedom, sample size, and the exact probability of error α must be given, as pointed out in the following example: The sample included 30 single people, 54 married people, 26 divorced, and 16 widows. These frequencies were significantly different, χ2(3, N = 126) = 10.1, p = 0.017. Some statistic programs only deliver a limited number for decimals for p and often the value given is 0.000 or 0.00. As p is a probability and not a certainty, in those cases it must be reported as p < 0.001 or p < 0.01, respectively. Often, when calculating c2, one or more cells have expected frequencies under five, which inflates such value. If this is the case, the number of cells which expected frequency lower than five must be pointed out.
Pearson’s correlation coefficient (r). When reporting results of the Pearson’s correlation (r), besides the r value, the sample size used to calculate the correlation must be pointed out (in parentheses and with no space between r and the parentheses) along with the exact probability of error α. Example: The correlation between both variables was highly significant, r(365) = 0.32, p = 0.008. The same comment included above regarding p values provided by statistical programs applies in this case.
When a table with the correlations is included, a column must be added to point out the exact probability of error α of each correlation. An alternative is to point out at the foot of the table the error α probability of each correlation, generally with asterisks: * for p < 0.05, ** for p < 0.01 and *** for p < 0.001.
Student’s Test. When the results of a Student’s test are reported, besides the t value, the degrees of freedom must be pointed out (in parentheses and with no space between t and the parentheses), the exact probability of error α (when the test is bilateral it is not necessary to point it out; when it is unilateral it must be reported), some measure of the effect size (strength of association between variables), such as Cohen’s d and the confidence interval of the means (CI) in brackets, the upper limit and the lower limit separated by a comma and a space, preceded by the significance level. The significance level must be uniform throughout the text and corresponding tables. The comment above regarding the value of p provided by statistical programs also applies in this case. Examples:
The participants in the program were significantly older (M= 24.24, SD = 2.63, n = 17) than the control group (M= 20.65, SD = 2.52, n = 20), t(35) = 4.23, p < 0.001, d = 1.39, 95% CI [1.86, 5.31].
After the treatment for anxiety, the experimental group had a lower mean of the anxiety score (M= 20.46, SD = 2.11, n = 13) than the group which did not receive the treatment (M= 24.00, SD = 3.06, n = 13); therefore, it can be concluded that the treatment lowered anxiety levels, t(24) = -3.44, p = 0.004 (unilateral), d = -1.35, 99% CI [-6.42, -0.66].
Variance analysis. It may be related to one factor or more (factorial).
One factor. When reporting the results of a one factor analysis of variance , besides the value of the F ratio, indicate the degrees of freedom of the numerator and denominator (in parentheses separated by a comma and with no space between the F value and the parentheses), the exact probability of error α, some measure of the size of the effect (strength of the relation), which may be Eta squared (η2) or the determination coefficient (r2), and the confidence interval for the mean in each condition (CI) in brackets, the upper limit and the lower limit separated by a comma and a space preceded by the significance level. It is not necessary to repeat the significance level for the confidence interval of the mean in each condition. Also, the means, standard deviations and sample sizes must be pointed out for each cell (condition) and the results of the analysis of homogeneity of variances and of the post-hoc hypothesis analysis. Example:
The 12 participants who received a high dose had a reaction time of 12.6 seconds (SD= 1.4); the nine participants who received a moderate dose had a reaction time of 7.7 seconds (SD= 2.1), and the eight participants of the control group had an average of 6.1 seconds (SD= 1.1). The Levene’s test (1.54, p = 0.23) allows us to conclude that the variances of the three groups may be considered equal. The effect of the dosage, therefore, was highly significant, F(2, 26) = 46.24, p < 0.001, r2 = 0.78, 95% ICs [11.7, 13.5], [6.0, 9.3], and [5.2, 7.1], respectively. The Scheffe’s test revealed that the differences were produced between the group which received a high dose and the other two (p< 0.001), while the group which received a moderate dose did differ significantly from the control group (p= 0.157).
Factorial. When the results of a factorial variance analysis are reported, besides the value of F ratio, indicate the degrees of freedom of the numerator and denominator (in parenthesis separated by a comma and with no space between the F value and the parentheses), the exact probability of error α, some measure of the size of the effect (strength of the relation), which may be Eta squared (η2) or the coefficient of determination (r2), and the confidence interval for the mean in each condition (CI), in brackets, the upper limit and the lower limit separated by a comma and a space preceded by the significance level. Besides the means, standard deviations and the sample size must be pointed out for each cell (condition). When there is too much information, it is necessary to report it in a table, not repeating it in the text, but instead referring to the table in the text.
Linear Regression. When reporting the results of a linear regression, indicate the standardized coefficients (betas) and their associated probabilities (p), as well as the square of the multiple correlation coefficient (R2) and the F ratio, the degrees of freedom of the numerator and denominator (in parentheses separated by a comma and with no space between the F value and the parentheses), the probability of error (p) and the confidence interval for the betas (CI) in brackets, the upper limit and the lower limit separated by a comma and a space preceded by the security level. It is not enough to say that a given percentage of the variance is explained; it must be specified which variable or construct variance is explained. Example:
Achievement scores were regressed considering the size of the class and the amount of tasks assigned. These two predictors explained almost half of the variance of the achievement test scores (R2 = 0.49), which is highly significant, F(2, 289) = 12.5, p = 0.005. Both the number of tasks assigned, β = 0.46, p = 001, 95% CI [0.39, 0.55], and the size of the class, β = 0.28, p = 0.014, 95% CI [0.20, 0.35], had significant effects on the achievement scores.
Missing values. In any analysis carried out, missing values must be reported, either as an absolute or relative frequency. In addition, authors must point out how they were handled in the analysis and how they affected the results.
The following ethical aspects must be considered:
Error reporting. If the author of an article notices, after submitting it to the journal, or even after it has been published, that there is a mistake in the analysis or interpretation of data, he/she must inform the journal about it. Likewise, the author must not conceal information which may seem problematic in his/her research, and should report it.
Data retention. The author of the article must be willing to provide all the information that the editor of the journal may request. If he/she does not, his/her article may not be published. Once published, the author of the article must be willing to submit the data to other qualified researchers who may request him/her to do so in order to confirm the analysis and the results. The data must be available for at least five years after the publication of the article.
Data duplication. Data duplication is forbidden, and refers to the duplication of data or ideas in two or more sources. If there is any slight duplication, this must be pointed out in the Author’s note. Also, if with the information obtained from a study several articles will be written, the author must inform about this situation to the editor of the journal in order for him to determine if several articles can be published or if the information must be given as a whole in one article. If figures or tables are going to be reused from other articles, the author must expressly point this out through a foot note.
Plagiarism and self-plagiarism. The researcher must give credit for all the information and ideas of another author, paraphrasing or quoting the author of those ideas. Besides, if the study resulted from a suggestion given by another author in the conclusions of his/her article, this must be also acknowledged. Furthermore, there must not be self-plagiarism, which is to present information, terms, or ideas as original when they have already been published in another article or book. If it is necessary to refer to them, the original source must be clearly referenced.
Rights and confidentiality of participants. The researcher must follow and report in his/her article the ethical standards followed in relation to the participants of the study. If this is not done, the journal may choose not to publish the article or to retract the article after it has been published. Special care must be taken with the confidentiality of the information given by the participants and the safekeeping of their identities, as well as that of their families.
Conflict of interest. The author of the article must point out in the Author’s Note any situation that the readers may interpret as a conflict of interest, for example, owning the copyright to an instrument used in the study or being biased against other instruments.
Use of unpublished instruments, procedures or data. If another author’s instrument, procedure or data is used, the author of the article must request his/her consent to use it, reporting it on a footnote in the appropriate place.
Use of copyrighted or trademarked instruments, procedures, or data. If the instrument or procedure is under copyright or trademark, the consent granted by the author, the royalties paid, or any other actions required for their use must be pointed out. It is strictly forbidden to use copyrighted instruments or procedures without their owner's consent, or through techniques such as illegal copying.
Citing References in Text
Non-verbatim quotations. Everything which is not originally by the authors of the article must be cited, pointing out the author or authors and the year of the publication of the reviewed work. This information must be exactly the same as the one that appears in the alphabetic reference list at the end of the article. Example: ...non-verbatim idea (Rogers, 1994). Suffixes such as Jr. must not be included in the quotes.
If the quoted work has up to five authors, the first time the reference is presented all of them must be included, followed by the year. The next times all of them are included if the authors are one or two; if they are three to five, the last name of the first author is written, followed by “et al.” and the year of publication. If they are six of more authors, the first and subsequent times the surname of the first author is included followed by “et al.” and the year of publication. Example: ...non-verbatim idea (Payne, Whitehurst, & Angell, 1994). Second time and subsequently: ...non-verbatim idea (Payne et al., 1994). Exception: if two references with more than three authors and with the same year are cited, the quote will be shortened naming the first author and the necessary ones in order to distinguish the two references, followed by et al.
Example: If the references are Castro, Zúñiga, Pereira, Valdivia, and Ossandón (2001) and Castro, Zúñiga, Silva, Valdivia, and Montero (2001), the quote is: (Castro, Zúñiga, Pereira, et al., 2001; Castro, Zúñiga, Silva, et al., 2001). If the years are different, the exception does not apply.
If the quote corresponds to the work of an institution, the first time it is quoted the full name of the institution must appear, followed by its abbreviation between brackets. The following times it is quoted, only the abbreviation is indicated. Do not use the abbreviation if it will not be used again in the text. Example: ...non-verbatim idea (Fundación Educacional Arauco [FUNDAR], 2004). Second time and subsequently: ...non-verbatim idea (FUNDAR, 2004).
If several works related to an idea are cited, the authors are included in parentheses in alphabetical order and separated by semicolons. Example: ...non-verbatim idea (Jonson, 1997; Parkin, 1996; Spencer & Raz, 1994).
If citing an author that is quoted in the work of someone else, indicate the former first followed by the year of publication, followed by “cited in” and the surname of the author and year in which it was quoted. The work of the main author whose work was effectively reviewed must be entered in the reference list. Nevertheless, whenever possible, the original work should be read and quoted. Examples: ...non-verbatim idea (Kobak, 1989, cited in Crowell & Treboux, 1995). Kobak (1989, cited in Crowell & Treboux, 1995) points out that...
If two or more works by the same author are quoted at the same time, his/her/their surname/s are indicated only once followed by the years of publication in parentheses, from oldest to newest, separated by comas. Example: ...non-verbatim idea (Bandura, 1969, 1973, 1977).
If works by the same author (or by the same two or more authors in the same order) with the same publication date are quoted, they must be identified by the letters a, b, c after the year. These letters are assigned, in accordance to the order in which they are quoted in the text, repeating the same order in the reference list. Examples: Varela (2000a) points out that …; …non-verbatim idea (Varela, 2000a, 2000b).
When quoting works of authors in which the first author and date of publication are the same but the other authors are different, the first time it is quoted all the surnames are written (if they are five or less) and, to differentiate them, the second time and subsequently, the first and second authors’ surnames are written, followed by the year of publication. Examples:
Roberts, Ferguson, McDonald, and Morris (1992) think that… (firstquote)
When two works with the same date and by authors with the same surname (but different authors) are quoted, the initials of the author’s first name are entered to differentiate them. Examples: (Y. Mergusen, 1991); (S. E. Mergusen, 1991).
When two works by different authors with the same surname and the same first name initials are quoted, the full names of each are written to differentiate them. Examples: (Paul Janet, 1876), (Pierre Janet, 1906).
When a translated or republished work is quoted, the year of the original work is placed, slash, year of republishing. Example: (Freud 1900/1953).
When a work has several volumes with different years and they are all quoted, the first-last years are placed. Example: (Koch, 1959-1963).
When dealing with a paper, conference or poster presented in a symposium, seminar, or another event, besides the year, the month is written (starting with capital letters). Example: (Hoffman, L. & Goolishian, H., 1989, June).
When dealing with an article read in a newspaper, newsletter, or written bulletin, the exact date when it was written is pointed out. Example: (Arrigo & Welch, 2008, July 22).
If the work has no author, including legal material, quote the first words of the title (using capital letters of the main words) and the year. If it is the title of an article or a chapter, it must go between double quotation marks; if it is a magazine, book or report, it must be in italics. Examples: ...non-verbatim idea (“Study Finds”, 1982); ...as is pointed out in the book College Bound Seniors (1979).
If the publication date is not applicable, as in the case of ancient books, quote the year of the translation used, preceded by trans., or the year of the version used, followed by version. Example: (Aristotle, trans. 1931). If the date of the original publication is known, include it in the quotation. Example: (Castelleto, 1890/1995).
To quote a specific part of a source, the page, chapter, figure, table, or equation must be indicated. Page is abbreviated (p.), but not chapter. Examples: (World Health Organization, 2004, p. 15); (Portales, 2005, Chapter 4).
To cite an interview or personal communication, the initial of the first name, surname, personal communication and precise date are placed. Since it is not possible to retrieve the information of personal communications, they are not included in the reference list. Example: (J. Smith, personal communication, August 15, 2001).
Verbatim quotations. If the idea is quoted verbatim, it must be placed between double quotation marks, followed by the page number of the work from which it was taken. If part of the text is omitted, it is replaced by (…). When something is added to the quote which was not written by the author, it must be placed in square brackets. Examples:
“Men act in the world and change it; in turn they are changed by the consequences of their actions” (Skinner, 1981a, p. 11).
“The incorporation of women into the labor market (...) is the most important explanatory action in the configuration of the modal Chilean family” (Muñoz, Reyes, Covarrubias, & Osorio, 1991, p. 29).
If the quote was taken from an electronic source with no page numbers, use the paragraph number if available, preceded by the abbreviation “para.”. When there are no visible paragraph numbers, the subtitle or section in which the quote appears and the paragraph number within the subtitle must be written. Examples: ...verbatim quote (Myers, 2000, para. 5); ...verbatim quote (Beutler, 2000, Conclusions, para. 1).
If the verbatim quote is 40 words or longer, a new line must be started, with an indentation of 0.63 cm on the left and right margins for the whole block, leaving a 3-point space before and after the quote. Quotation marks must not be written, and the corresponding source must be indicated, followed by the page or pages of the text from which the quote was extracted, in parentheses after the full stop. No period is needed after the parenthesis. Example:
Schools have had to relegate this vital element to the social subjects of the curriculum, where democratic participation is generally taught through readings and text books rather than through involving young people in activities that contribute to the well-being of others and society. (p. 27)
Each reference cited in the text must appear in the reference list and each entry in the reference list must be cited in the text. Moreover, there must be total coincidence in the spelling of author’s name and year of publication on both parts of the article. Classical works, such as religious books or ancient Roman or Greek texts, or personal communications, are not listed in the reference list.
Order of references in the reference list. Entries in the reference list must be placed in strict alphabetical order considering the first author’s surname. When the reference has no author, the title of the article should be written (from the first main word, omitting articles).
Reference elaboration in relation to the type of work. The surname and the initial of the first name must be provided (the two first initials—or three—when the author has two—or three—names or has a name and an initial or initials, as is often the case with North American writers) for all the authors if they are seven or less.
If the authors are seven or fewer, all of them are listed. Example: Vinet, E., González, M. E., Alarcón, P., Salvo, S., Pérez, V., & Díaz, A. (2004).
If the authors are eight or more, the first six of them are listed, then three ellipses are inserted (…) and the name of the last author is added. Example: If the authors of a work are Sadek, J., Johnson, S., White, D., Salmon, D., Taylor, K., Paulsen, J., Heaton, R., & Grant, I., the entry of this work in the reference list will be as follows:Sadek, J., Johnson, S., White, D., Salmon, D., Taylor, K., Paulsen, J. … Grant, I. (2002).
Place a period after every initial. Use a comma to separate the author’s surnames and initials and to separate the authors between them. Use “&” before the last author. Example: Clark, M., Rosen, G., Tallal, P., & Fitch, R. (2000).
If two authors have the same surname and share the initial of their first names, write in brackets the name of each one. Example: Janet, P. [Paul]. (1876). La notion de la personnalité [The concept of personality]. Revue Scientiﬁque, 10, 574-575. Janet, P. [Pierre]. (1906). The pathogenesis of some impulsions. JournalofAbnormalPsychology,1,1-17.
In order to highlight the first author’s surname, the second and following lines of the reference must use a left indentation of 0.63 cm.
