Abstract

Abstract Introduction: Social support is an essential component for the physical and emotional well-being of postpartum mothers. The objective of this study is to determine the psychometric properties of the revised Malay version Medical Outcome Study (MOS) Social Support Survey using a confirmatory validity approach. Methods: A cross-sectional study was conducted involving 144 postpar- tum mothers attending Obstetric and Gynecology Clinic, Universiti Sains Malaysia Hospital. Construct validity and internal consistency assessment was performed after the translation, content validity and face validity process. The data were analyzed using SPSS 20.0 (SPSS Inc., Chicago, IL, USA) and AMOS 20.0 (SPSS Inc., Chicago, IL, USA). Results: The original questionnaire consists of four domains (emotional/ informational support, tangible support, affectionate support and positive social interaction) and 19 items. Affectionate support domain with three items only was treated as a separate construct and was not included in the factor analysis. The final confirmatory model with three constructs and 13 items demonstrated acceptable factor loadings, domain to domain corre- lation and best fit; (χ2[df] = 1.665 [61]; P-value = 0.001; Tucker–Lewis Index = 0.944; comparative fit index = 0.956; root mean square error of approximation = 0.068). Composite reliability, average variance extracted and Cronbach’s α of the domains ranged from 0.649 to 0.903; 0.390 to 0.699; 0.616 to 0.902, respectively. Conclusion: The study suggested that the four-factor model with 16 items (including one separate factor of affectionate) of the revised Malay version MOS Social Support Survey was acceptable to be used to measure social support support after childbirth because it is valid, reliable and simple.
