| Abstract: | In this study, we examined estimates of internal consistency reliability, measurement invariance, and differential correlates of the Multidimensional Scale of Perceived Social Support (MSPSS; Zimet, Dahlem, Zimet, & Farley, 1988) in samples of undergraduate men (n = 270) and women (n = 340). The MSPSS is designed to assess 3 sources of perceived social support: family, friends, and significant others. The participants ranged in age from 18 to 24 years (M age = 19.60, SD = 1.4 years). First, composite scale reliability and coefficient omega methods provided adequate estimates of internal consistency reliability for the original MSPSS total and subscale scores. Second, results of multiple-groups invariance confirmatory factor analysis provided support for configural and metric invariance. Partial measurement invariance was attained for scalar and strict measurement invariance across men and women. Additionally, given the high correlations among the first-order factors, we conducted multiple-groups bifactor item response theory (bifactor-IRT) analysis to evaluate further the performances of the individual MSPSS items across gender. Support for the bifactor model was strong. Third, we conducted a series of simultaneous regression analyses to identify potential correlates of the social support construct for women and men. |
