Motivation matters: Development and validation of the Motivation for Solitude Scale – Short Form (MSS‐SF)

Confirmatory Factor Analyses resulted in a two-factor solution, selfdetermined solitude (SDS) and not self-determined solitude (NSDS), and showed the MSS-SF to be reliable with adolescents and emerging adults, with satisfactory convergent and discriminant validity. Engaging in solitude for extrinsic, not self-determined reasons was associated with loneliness, social anxiety, and depressive symptomatology; in contrast, solitude chosen for intrinsic, self-determined reasons was positively correlated with well-being, for emerging adults in particular. The MSS-SF goes beyond preference for solitude to distinguish two distinctly different motivations for solitude, and in so doing, allows researchers to better understand the affordances and risks of being alone for adolescents and emerging adults.
