Social support and social network scales were reviewed from a psychometric perspective. A sample of 29 behavioral science studies were selected from social support and social network articles published between 1967 and 1982. Each study was classified according to psychometric issues of scaling, reliability, and validity. The review was motivated by the hypothesis that many social support and social network scales are developed without complete utilization of existing measurement technology. Results of this review confirm this hypothesis. Limited availability of basic psychometric data for such scales attenuates theory development and research efficiency. Researchers in this field are encouraged to increase the availability of basic psychometric information for social support and social network scales.
