Abstract This study aimed at developing an integrative measure of SSG based on the integrative SSG construct. The final version of the scale involves 14 items loading on 4 factors: affectiveness, formal exchange, favor exchange, and obligation. The construct of SSG typology was also tested with cluster analysis based on the integrative SSG scale. Various reliability and validity analysis showed that the integrative SSG scale possesses good psychometric properties, and makes unique contribution beyond the current SSG measures. It was indicated that the scale is a useful tool with integrative contents and clear constructs for future research.
