Notes:
a
The Group × Time interaction for CMT was also significant with baseline CMT as a covariate: Parameter estimate=0.16, t=2.12, p=.038. CMT=Comprehensive Modules Test; PANSS=Positive and Negative Syndrome Scale; BAI; Beck Anxiety Inventory; BDI-II=Beck Depression Inventory-II; LSI=Life Satisfaction Index; DPAS=Defeatist Performance Attitude Scale; SERS=Self-Esteem Rating Scale.
Time in months was centered at baseline and group was coded: CBSST = 0.5 and GFSC = −0.5.
