Cross-Cultural Validity of Persian Version of Senior Perceived Physical Literacy Instrument

Objective: Given the growing elderly population in Iran and the relationship between physical literacy and health, assessing physical literacy in this population is important. However, there are limited studies on the assessment of physical literacy in the elderly. The present study aimed to examine the cross-cultural validity of the Persian version of Senior Perceived Physical Literacy Instrument (SPPLI).Method: At first, the translation/back translation process and content validity were carried out through the Content Validity Index (CVI) with opinion of five experts. Subsequently, concurrent and construct (age differences and convergent) validity, and internal consistency were examined in a sample of ۷۸ older adults (aged ۶۰–۹۰ years) randomly selected from nursing homes and physiotherapy centers in Qazvin. Construct validity of the SPPLI was assessed by comparing age-related differences and its correlation with age and its convergent validity with the Physical Activity Scale for the Elderly (PASE) and the short-form Falls Efficacy Scale-International (FES-I) and concurrent validity was evaluated through the its relationship with the Senior Fitness Test (SFT) as a measure of actual physical literacy.Results: The CVI results confirmed the content validity of all SPPLI items. The results of Mann-Whitney U test revealed no significant difference in perceived physical literacy between the two age groups (p = ۰.۴۲). Spearman’s correlation between total scores of SPPLI and age was weak and non-significant (r (۷۸) = ۰.۱۲۳). The Spearman correlation coefficients of SPPLI with total scores of SFT, PASE, and short FES-I were ۰.۵۰۱, ۰.۴۵۲, and -۰.۰۰۱, respectively.Conclusions: The content and concurrent validity of the SPPLI was confirmed, and its internal consistency was good. However, convergent validity was moderate with the PASE and very weak with the short FES-I, while construct validity based on age differences was not confirmed. In conclusion, the Persian SPPLI exhibits appropriate cross-cultural validity.
