Validation of a Computerized Version of the Trait Subscale of the Physical Appearance State and Trait Anxiety Scale in Mexican Preadolescents.

Anxiety is a feeling of fear, dread or restlessness and can develop into a weight-related disorder. The objective was to analyze the psychometric properties of the trait anxiety subscale of the Physical Appearance State and Trait Anxiety Scale (PASTAS), as well as the invariance in Mexican preadolescents. The sample consisted of 604 participants, 285 female and 319 male, whose ages ranged between 11 and 12 years (M = 11.37; SD = 0.48). The questionnaire's factor structure was analyzed using confirmatory factor analyses. The analyses show the viability and adequacy of a two-factor structure (weight and non-weight factors) both for the total sample and for the populations of male and female. The two-factor structure showed adequate reliability and validity fit indicators. The factor structure, the factor loadings and intercepts are considered invariant according to the variable sex; however, differences between female and male participants were found for levels of anxiety caused by physical appearance. In conclusion, the PASTAS can be considered a convenient instrument to assess the variables related to anxiety generated by one's physical appearance, as well as allowing more participants to be quickly assessed.

Composition and Factorial Invariance for the Assessment of Body Image Dissatisfaction Questionnaire in Mexican Adolescents.

Body image is a mental representation that a person has, which could become a body dissatisfaction due to the pressure exerted by the culture, affecting several life stages specially in adolescents. The aim of this study was to analyze the psychometric properties and factorial invariance of the questionnaire to assess body image dissatisfaction. The sample consisted of 552 Mexican teenagers, 259 female, and 293 male, with a mean age of 12.91 ± 0.96 years. Confirmatory Factor Analyses show that a five-factor structure is viable and adequate. The five-factor structure (perceptual, emotional distress, behavioral, proposal to change, and fear of gaining weight) show adequate fit indices and validity, even though the obtained model does not completely correspond to that proposed by the authors of the scale, it continues to endorse the multifactorial component of body dissatisfaction. On the other hand, the factorial structure, the factor loadings, and the intercepts are considered invariant in both populations; however, there are differences between the populations for the means of the perceptual, emotional distress, and fear of gaining weight factors. This study serves as a premise for future research on the study of instruments for measuring body image in populations with different personal and cultural factors.

V Coloquio Internacional de Psicología del Deporte Público REDDECA. Composición e invarianza factorial de la versión corta del Physical Self Description Questionnaire en adolescentes mexicanos / V Coloquio Internacional de Psicología del Deporte Público REDDECA. Composition and factorial invariance of the Short Version of the Physical Self Description Questionnaire among Mexican adolescents / V Coloquio Internacional de Psicología del Deporte Público REDDECA. Estrutura e invariancia fatorial do versão curta de Physical Self Description Questionnaire em adolescentes mexicanos

El objetivo de esta investigación fue analizar las propiedades psicométricas propuestas por Marsh, Martin y Jackson (2010) para la versión corta del Physical Self Description Questionnaire (PSDQ-S). La muestra total fue de 915 adolescentes mexicanos 400 deportistas y 515 no deportistas, con edades comprendidas entre 11-15 años (M = 12.33; DE = 1.43). La estructura factorial del cuestionario se analizó mediante análisis factoriales confirmatorios. Los análisis, muestran que una estructura de nueve factores (actividad física, apariencia, grasa corporal, coordinación, resistencia, flexibilidad, salud, competencia deportiva y fuerza) es viable y adecuada tanto para la muestra total (GFI .964; RMSEA .030; CFI .981) como para las poblaciones de adolescentes mexicanos deportistas (GFI .921; RMSEA .049; CFI .946) y no deportistas (GFI .943 y RMSEA .049; CFI .970). La estructura de nueve factores, atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Por otro lado, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes de acuerdo a la variable práctica deportiva; sin embargo, existen diferencias significativas a favor de los deportistas en cuanto a su autoconcepto físico: actividad física (-1.243, p <0.001), grasa corporal (-0.212, p <0.05), coordinación (-0.765, p <0.001), resistencia (-0.882, p <0.001), flexibilidad (-0.427, p <0.001), salud (-0.172, p <0.05), competencia deportiva (-1.026, p <0.001) y fuerza (-0.614, p <0.001). En conclusión, el PSDQ-S puede ser una herramienta útil para avanzar en el estudio de los factores que afectan al autoconcepto físico

The aim of this research was to analyze the psychometric properties proposed by Marsh et al. (2010) for the Physical Self Description Questionnaire (PSDQ-S). The total sample has been composed by 915 Mexican adolescents, 400 athletes and 515 non-athletes, with ages from 11 to 15 years (M = 12.31, SD = 1.43). The factor structure of questionnaire has been analized through the confirmatory factor analysis. This analysis shows that a nine factors structure is viable and adequate for the total sample (GFI .964; RMSEA .030; CFI .981) and the populations of athletes (GFI .921; RMSEA .049; CFI .946) and non-athletes (GFI .943 y RMSEA .049; CFI .970). The nine factors structure (physical activity, appearance, body fat, coordination, endurance, flexibility, health, sport competence, and strength), according to statistical and substantive criteria, has shown adequate indicators of reliability and validity adjustment. On the other hand, the factorial structure, the factorial loads and the intercepts are considered invariant according to the variable sports practice; however, there are differences between athletes and non-athletes in favor of athletes in terms of their physical self-concept: physical activity (-1,243, p <0.001), body fat (-0.212, p <0.05), coordination (-0.765, p <0.001), endurance (-0.882, p <0.001), flexibility (-0.427, p <0.001 ), health (-0.172, p <0.05), sports competition (-1.026, p <0.001) and strength (-0.614, p <0.001). In conclusion, the PSDQ-S can be a useful tool to advance in the study of the factors that affect the physical self-concept
