Modified Medical Outcomes Study Social Support Survey (mMOS-SS)

The Modified Medical Outcomes Study Social Support Survey (mMOS-SS) is an 8-item self-reported measure of individual experience of social support, with two subscale measures of emotional support, and instrumental support. Items ask respondents about having someone to help with physical needs, and emotional assistance. The mMOS-SS is an abbreviated adaptation of the original 19-item Medical Outcomes Study Social Support Survey (MOS-SS), which can be viewed here.
