Validation of the brazilian version of the Physical Self-Description Questionnaire – Short
Abstract
Objective: To analyze the validity and reliability of the statements and dimensions of the "Physical Self-Description Questionnaire - Short" (PSDQ-S) in Brazilian adults with and without disabilities.
Methods: The present study has a cross - sectional design and a retrospective feature. 998 Brazilian adults, with and without disabilities, participated in the study for the validity and internal consistency and 823 for reproducibility, of both sexes, from different regions of Brazil. The validity process was analyzed by the exploratory factorial analysis, the reproducibility by the intraclass correlation coefficient and the internal consistency by the Cronbach's alpha.
Results: The statements of physical self-concept showed factorial loads equal to or greater than 0.70, both for people with disabilities and for people without disabilities. Adequate reproducibility scores were found for both groups, with values ≥ 0.80. The internal consistency for the dimensions ranged from 0.77-0.95.
Conclusions: The dimensions of the “Physical Self-Description Questionnaire - Short“ presented adequate factorial validity, reproducibility and internal consistency, being recommended their use in studies that evaluate the physical self-concept of Brazilians with and without disabilities.
