GRIEP, Rosane Harter et al. Construct validity of the Medical Outcomes Study's social support scale adapted to Portuguese in the Pró-Saúde Study. Cad. Saúde Pública [online]. 2005, vol.21, n.3, pp.703-714. ISSN 1678-4464.

This paper evaluates the construct validity of the Medical Outcomes Study's social support scale adapted to Portuguese, when utilized in a cohort study among non-faculty civil servants at a university in Rio de Janeiro, Brazil (Pró-Saúde Study). Baseline data were obtained in 1999, when 4,030 participants (92.0% of those eligible) completed a multidimensional self-administered questionnaire at the workplace. From the original scale's five social support dimensions, factor analysis of the data extracted only three dimensions: positive social interaction/affective support; emotional/information support; and material support. We estimated associations between social support dimensions and socio-demographic, health, and well being-related characteristics. We confirmed the hypotheses that less isolated individuals, those with better self-rated health, those who reported more participation in group activities, and those with no evidence of common mental disorders reported better perception of social support. In conclusion, we found good evidence for a high construct validity of this scale, supporting its use in future analyses in the Pró-Saúde Study and in similar population groups.
