The MOS Social Support Survey is a 20-item self-reported measure of individual experience of social support with four subscale measures of emotional/informational support, tangible support, affection, and positive interaction. This survey-based scale measures participation in social activities, having someone to help with physical needs, and experiencing affection, companionship and assistance. An overall social support score can be generated by averaging item responses (items 2-20) and then transforming values such that the lowest possible score is “0” and the highest possible score is “100”. High scores reflect individuals who have more types of social support available to them, with great frequency, if needed. Items also can be combined to reflect the following four subscale measures of social support: emotional/information support (“E”), tangible support (“T”), affection (“A”), and positive interaction (“P”).
