German, Portuguese and Spanish Versions of the Revised Short Form of the Physical Self-Inventory (PSI-S-R)

ABSTRACT

The present study sought to examine the psychometric properties of new German, Portuguese, and Spanish versions of the Revised Short Form of the Physical Self-Inventory (PSI-S-R), and to contrast these properties against those from the original French version of this instrument. Participants (n = 1802) were 288 French youth, 177 German youth, 848 Portuguese youths and 489 Spanish youth. Results from exploratory structural equation modeling (ESEM) analyses supported the factor validity and reliability of PSI-S-R across the overall sample and each linguistic sample. Subsequent analyses supported the weak, partial strong, and strict invariance of this measure, and revealed a lack of differential item functioning (i.e., measurement bias) as a function of age, body mass index, sex and sport involvement across all linguistic versions. However, latent mean differences were observed as a function of these predictors and countries.
