Reported are the model-based means and standard deviations. Models were adjusted for non-ignorable dropout. BCR = basic cognitive rehabilitation; ECR = extensive cognitive rehabilitation; CI = confidence interval; SF GH = Short Form—General Health Perceptions; SF V = Short Form—Vitality; SF PR = Short Form—Physical Role Functioning; SF ER = Short Form—Emotional Role Functioning; SF MH = Short Form—Mental Health; SF SR = Short Form—Social Role Functioning; SF PF = Short Form—Physical Functioning; SF BP = Short Form—Bodily Pain; SD = standard deviation. T0 = baseline; T1 = mid-treatment; T2 = post-treatment.
