Following a brief explanation of the study of social support in families, the paper presents a selective list of measures of social support as well as a number of different outcome measures that support has been found to mediate. Key terms, (social networks, social support, well-being and stress, coping) are defined and research is cited to substantiate the contention that support mediates different outcomes. A matrix is then presented of approximately 100 measures of social support and other parent/family behavior characteristics. The matrix illustrates which scales measure which outcome variables. Another matrix presents reliability and validity information for selected scales. The final section provides 204 citations for the measurement scales and reports cited in the matrices and research referred to in the narrative. (CL)
