Note. BSI = Brief Symptom Inventory. LISRES = Life Stressors and Social Resources Inventory. SCQ = Situational Confidence Questionnaire. COPE = Coping Orientations to Problems Experienced inventory. COPES = Community Oriented Programs Environment Scale. CSQ = Client Satisfaction Questionnaire.

a = These variables were collected from the patient’s discharge summary notes. Internal consistency cannot be computed for these variables; however, interrater reliability estimates (i.e., Kappa coefficents) for these variables are provided in the text of the main article.

b = Scores on the program alliance composite were based a principal component analysis of scores on COPES-Involvement, COPES-Support, and the CSQ-total scores. These analyses were conducted separately at the 1-month and discharge time points and were standardized within time. Given that this is a composite variable, internal consistency reliability estimates were not computed.

a = coefficient alpha.
