Psychometric properties of the Body Image Dissatisfaction Questionnaire in university students

Abstract

Psychometric properties were determined in the Questionnaire of Dissatisfaction with Body Image(IMAGEN) in students of the National University of Trujillo. The non-random probability sample (n =576) of a population (N = 1272), with a Psychometric design. The results showed that IMAGEN had a valid item-scale construct validity, with very significant correlation indices (p <.01) with its components and with the test, good levels of discrimination that fluctuated (.465 - .843). Factor analysis ratified the cognitive behavioral structure, indexes that vary between .915 and .931. Congruent validity reflected a very strong global correlation (r = .899) with BSQ as well as with factor 1 of the aesthetic models questionnaire (r = .823). The reliability by internal consistency is high (α = .953). Stability established a high significance (p <.01) of the test.
