Multidimensional Scale of Perceived Social Support

The Multidimensional Scale of Perceived Social Support (MSPSS) is a widely used psychological measurement instrument to assess an individual's perceived social support from three sources: family, friends, and a significant other. The instrument consists of 12 self-report items, grouped into three corresponding subscales. Responses are recorded using a Likert-type scale, and scores may be calculated for each subscale as well as for an overall measure of perceived social support.

The scale was developed during the early to mid-1980s by Gregory D. Zimet, Nancy W. Dahlem, Sara G. Zimet, and Gordon K. Farley, and was first published in 1988 in the Journal of Personality Assessment. It was designed as a brief measure of perceived social support for use in research settings. It has been applied in numerous peer‑reviewed studies, across many populations and cultural contexts, to assess perceived social support in both clinical and non‑clinical settings.
