MAFLA, Ana Cristina; VILLALOBOS, Fredy Hernán; PINCHAO RAMIREZ, Wilson Marino  y  LUCERO YELA, Diego Fernando. Psychometric Properties of the Spanish Version of the Abeer Children Dental Anxiety Scale (ACDAS) to Dental Anxiety in Children. Int. J. Odontostomat. [online]. 2017, vol.11, n.2, pp.182-191. ISSN 0718-381X.

The validity and reliability process of dental anxiety scales for children in Spanish has been scarce. The aim of this research was to determine the psychometric properties of a Spanish adaptation of the Abeer Children Dental Anxiety Scale (ACDAS) as a self-report measure of dental anxiety in children. The ACDAS includes 13 items about the anxiety reactions of receiving dental care and a cognitive component assessed to children, parents and operators. We adapted the Abeer Children Dental Anxiety Scale to Spanish language, and then determined its psychometric properties in a sample of 200 children patients from the Dental Clinic at Universidad Cooperativa de Colombia, Pasto, Colombia. The scale's structural validity was estimated through an Exploratory Factor Analysis (EFA) and the reliability was established by examining its internal consistency (Cronbach's a). The consecutive sample was comprised of 112 men and 88 women and their ages ranged from 5 to 10 years. The EFA loaded a four-factor structure which accounted for 72.12 % of the variance. We labeled to those factors according to anxiety reactions to potential harmful stimuli as "pre-intervention stimuli", "invasive/restrictive stimuli", "innocuous stimuli (touch, taste)" and innocuous stimuli (smell, hearing)". The internal consistencies of the sub-scales were 0.88, 0.71, 0.84 and 0.76, respectively. The sub-scales showed good convergent, discriminant and construct validity. The results suggest the ACDAS is a valid, reliable, and clinically useful instrument for assessing dental anxiety in children.
