Translated the Physical Self Description Questionnaire for the assessment of adolescent physical self-concept into Italian and analyzed its psychometric properties, factorial structure, reliability and gender factorial invariance. Participants were 755 13-17 yr olds. Factorial structure was examined with confirmatory procedures, Cronbach's alpha coefficient and item-total correlations were used to verify reliability, and various constrained models were compared to verify gender invariance. Results show that both the 11-oblique-factor structure and a good internal consistency of the questionnaire and its subscales were confirmed. The results supported the invariance of factor loadings across gender. Structural equation modeling supported a hierarchical structure among self perception elements. It is concluded that although the factors of the Italian version are somewhat less defined than those of the Australian version, on a global level the instrument has good validity and reliability, and confirms the factor structure and invariance across gender.

Abstract

Translated the Physical Self Description Questionnaire for the assessment of adolescent physical self-concept into Italian and analyzed its psychometric properties, factorial structure, reliability and gender factorial invariance. Participants were 755 13-17 yr olds. Factorial structure was examined with confirmatory procedures, Cronbach's alpha coefficient and item-total correlations were used to verify reliability, and various constrained models were compared to verify gender invariance. Results show that both the 11-oblique-factor structure and a good internal consistency of the questionnaire and its subscales were confirmed. The results supported the invariance of factor loadings across gender. Structural equation modeling supported a hierarchical structure among self perception elements. It is concluded that although the factors of the Italian version are somewhat less defined than those of the Australian version, on a global level the instrument has good validity and reliability, and confirms the factor structure and invariance across gender.
