  1. Notes. Feedback condition (n = 17), control condition (n = 9). Degrees of freedom: F tests (1, 24), χ2 test (1). †p < .10 (one-tailed), *p < .05 (one-tailed). CSQ = Client Satisfaction Questionnaire. COPES = Community Oriented Programs Environment Scale. LISRES = Life Stressors and Social Resources Inventory. The program alliance composite represents the average of the standardized (z) scores on the CSQ, COPES, and LISRES indices.
