Psychometric properties of the Motivation for Solitude Scale–Short Form in a sample of South African adolescents

With expanding interest in the role of solitude in healthy psychological development during adolescence, there is a need for psychometrically sound solitude measures. The aim of this study was to examine the psychometric properties of the Motivation for Solitude Scale–Short Form by evaluating its internal consistency, factor structure, and convergent and discriminant validity using a group of South African adolescents (n = 818). Results revealed satisfactory internal consistency for each of the two subscales, as well as good convergent and discriminant validity. Confirmatory factor analysis supported a two-factor higher order model as providing the best fit. The Motivation for Solitude Scale–Short Form seems to be a valid measure of motivation for solitude among South African adolescents and provides an avenue for further research on the role of solitude in adolescent well-being.
