Denotes measures in which lower scores are better. Bold font denotes p<.05 and corresponding effect size.

CPT-IP=Continuous Performance Test—Identical Pairs; MIST=Memory for Intentions Screening Test; UPSA=University of California, San Diego Performance-Based Skills Assessment; SSPA=Social Skills Performance Assessment; ILSS=Independent Living Skills Survey; QOLI=Quality of Life Interview; PANSS=Positive and Negative Syndrome Scale; HAM-D=Hamilton Depression Rating Scale. In addition to the independent variables of visit, group, and visit × group, the following covariates were included: age, education, sex, minority minority status, diagnosis, and intervention sessions. Effect size interpretation for r: small=0.10; medium=0.30; large=0.50 (Cohen, 1992).
