Cooperation and trust are the basis for all social skills. This assessment was developed for adults and adolescents with chemical dependencies to measure levels of cooperation and trust and the effectiveness of treatment in improving a client's ability to cooperate and trust. Criterion-related validity (r=.79) suggests that this test provides a moderately good assessment of a client's perceived cooperation and trust. Internal consistency (alpha) was measured during two different studies (N=92 and N=20) with a .91 and .76 respectively. Test-retest (N=115) was .725. Readability: Flesch grade level = 10.7.
