Validity and reliability of the Malay version multidimensional scale of perceived social support (MSPSS-M) among teachers

The multidimensional scale of perceived social support (MSPSS) was developed to measure perceived social support. It has been translated and culturally adapted among natives literate in the Malay language. However, its psychometric properties for teachers who are majority females and married have not been assessed.

This was a cross-sectional study conducted among the public secondary school teachers in the central region of Peninsular Malaysia from May to July 2013. A total of 150 and 203 teachers were recruited to perform exploratory factor analysis and confirmatory factor analysis (CFA), respectively. Reliability testing was evaluated on 141 teachers via internal consistency and two-week interval test–retest.

The 12-item three-factor structure of MSPSS-M was revised to 8-item two-factor structure. The revised MSPSS-M demonstrated excellent fit in CFA with adequate divergent and convergent validity and good factor loadings (0.80–0.90). The revised MSPSS-M also displayed good internal consistency with Cronbach’s alpha of 0.91, 0.93 and 0.92 and good test–retest reliability with intraclass correlation of 0.89, 0.88 and 0.88 in the total scale, family and friends factors, respectively.

The revised 8-item MSPSS-M is a reliable and valid tool for assessment of perceived social support among teachers.
