Abstract: The present study analyses the psychometric properties of the Body Image Anxiety Scale (BIAS) on students of Social Sciences. The total sample comprised 589 participants; 376 women and 213 men, all of them freshman at Universidad Autónoma de Chihuahua in the area of social sciences, with a mean age of 18.24 years (DS = 0.73). Psychometric analysis showed that a two-factorial structure was viable and adequate. The factor structure of the questionnaire was analyzed with confirmatory factor analysis (CFA). The structure of the two factors, attending to substantive and statistic criteria, showed adequate indicators of adjustment of reliability and validity. In addition, factor analysis conducted with subsamples indicated the presence of strong evidence of factor structure stability. Future research should replicate these findings in larger samples.


Keywords: instrument construction; factor structure; measurement invariance; instrumental study; construct validation; structural equation.
