Assessing the level of perceived social support among community-dwelling stroke survivors using the Multidimensional Scale of Perceived Social Support

Abstract

Abstract Social support has an important role in stroke rehabilitation. The Multidimensional Scale of Perceived Social Support (MSPSS) is an instrument examining the adequacy of perceived social support. However, the psychometric properties of the Chinese version of MSPSS (MSPSS-C) have not been examined in Chinese people with stroke. This study aimed at investigating the psychometric properties of the MSPSS-C, identifying the correlations between MSPSS-C scores and health-related measures of these people; and examining the differences in the levels of perceived social support between people with and without stroke in Hong Kong using a cohort of 57 community-dwelling people with stroke and 50 age-matched healthy controls. We found that the MSPSS-C subscales demonstrated excellent internal consistency, and a ceiling effect was observed for the family subscale of the MSPSS-C. The total MSPSS-C score had significant weak to moderate correlations with the scores of the concerned variables of interests. Exploratory factor analysis revealed a two-factor structure for the MSPSS-C. People with stroke had lower levels of perceived social support from friends and their significant other than those without stroke. The MSPSS-C is a valid tool for assessing perceived social support among chronic stroke survivors with moderate to very severe motor impairment.
