Abstract:
The sexuality of older people was understood as non-existent or as something outside the prevailing norm. In this sense, analysing people's sexual knowledge and attitudes towards older people is a challenge for theory and practice. The aim of this study is to translate and validate the Aging Sexual Knowledge and Attitudes Scale (ASKAS) for the Portuguese population. A sample of 994 Portuguese adults (70.9% women, n = 705) completed the ASKAS-PT along with a series of self-report measures. Confirmatory factor analysis and the psychometric properties of the Portuguese (European) version of ASKAS-PT were investigated, particularly reliability, temporal stability, and convergent and critical validity. This study also examined the gender measurement invariance of the ASKAS-PT. After confirmatory factor analysis, a two-factor model fit the Portuguese version best. Reliability and validity results also showed good results, and the ASKAS-PT appears to be a gender-invariant measure. Overall, the Portuguese version of the ASKAS showed good psychometric properties and appears to be a valid and reliable measure for assessing knowledge and attitudes about aging.
