Psychometric evaluation of the situation test of heterosocial skill

This study examined various psychometric properties of Forms A and B of the Situation Test, developed by Rehm and Marston (Journal of Consulting and Clinical Psychology, 1968, 37, 565–574) for the assessment of heterosocial skill and anxiety. A third test form composed of heterosocially irrelevant items was also examined for comparison purposes. Split-half, alternate-form, and interresponse consistency was determined for measures of skill, anxiety, response latency, and response duration. Differences across test forms on these measures were also investigated. Subsequently, criterion-related validity was examined relative to three criteria of heterosocial skill. Results indicated that two measures, anxiety and response duration, displayed adequate internal consistency, while that of skill and response latency was marginal. Interresponse consistency was moderately low for all three test forms. Comparisons of mean performances across forms revealed significant differences, with heterosocially irrelevant items appearing easier, in general, than the heterosocial items of Forms A and B. Lastly, significant predictions of peer-reported heterosocial behavior were obtained for all three test forms, but two self-report criteria were not found to be related to test behavior. Various implications of these findings are discussed.Portions of this research were completed while the authors were affiliated with the University of Georgia, Athens, Georgia.
