We developed and tested the validity of a brief scale to assess everyday functioning in persons with serious mental illness. A sample of 434 adults with schizophrenia or schizoaffective disorder were administered the University of California, San Diego, Performance-Based Skills Assessment (UPSA), which assesses functional skills in 5 areas of life functioning (eg, finances and planning). Through use of factor analysis, we developed the UPSA-Brief, which consists of 2 subscales (communication and financial) from the original UPSA. UPSA-Brief scores were correlated with cognitive functioning, symptoms of psychosis, age, and education. We further tested the sensitivity and specificity of the UPSA-Brief for predicting residential independence using receiver-operating characteristic (ROC) curves. Finally, sensitivity to change was assessed through comparison of 2 interventions for improving UPSA-Brief scores. UPSA-Brief scores were highly correlated with scores on the full version of the UPSA (r = .91), with overall cognitive functioning (r = .57), and with negative symptoms (r = -.32). The discriminant validity of the UPSA-Brief was adequate (ROC area under the curve [AUC] = 0.73; 95% confidence interval [CI]: 0.67-0.78), with greatest dichotomization for the UPSA-Brief at a cutoff score of 60. The UPSA-Brief was significantly better than the Dementia Rating Scale, Positive and Negative Syndromes Scale positive, and Positive and Negative Syndromes Scale negative at predicting residential independence (all P values < .05). Participants receiving a behavioral intervention also improved significantly compared with a support condition (P = .023). The UPSA-Brief has adequate psychometric properties, predicts residential independence, is sensitive to change, and requires only 10-15 minutes to administer. Therefore, the UPSA-Brief may be a useful performance-based functional outcome scale.

The current study was an updated meta-analysis of manuscripts since the year 2000 examining the effects of homework compliance on treatment outcome. A total of 23 studies encompassing 2,183 subjects were included. Results indicated a significant relationship between homework compliance and treatment outcome suggesting a small to medium effect (r = .26; 95% CI = .19–.33). Moderator analyses were conducted to determine the differential effect size of homework on treatment outcome by target symptoms (e.g., depression; anxiety), source of homework rating (e.g., client; therapist), timing of homework rating (e.g., retroactive vs. contemporaneous), and type of homework rating (e.g., Likert; total homeworks completed). Results indicated that effect sizes were robust across target symptoms, but differed by source of homework rating, timing of homework rating, and type of homework rating. Specifically, studies utilizing combined client and therapist ratings of compliance had significantly higher mean effect size relative to those using therapist only assessments and those using objective assessments. Further, studies that rated the percentage of homeworks completed had a significantly lower mean effect size compared to studies using Likert ratings, and retroactive assessments had higher effect size than contemporaneous assessments.

Mobile devices can be used to deliver psychosocial interventions, yet there is little prior application in severe mental illness. We provide the rationale, design, and preliminary data from 3 ongoing clinical trials of mobile interventions developed for bipolar disorder or schizophrenia. Project 1 used a personal digital assistant to prompt engagement in personalized self-management behaviors based on real-time data. Project 2 employed experience sampling through text messages to facilitate case management. Project 3 was built on group functional skills training for schizophrenia by incorporating between-session mobile phone contacts with therapists. Preliminary findings were of minimal participant attrition, and no broken devices; yet, several operational and technical barriers needed to be addressed. Adherence was similar to that reported in nonpsychiatric populations, with high participant satisfaction. Therefore, mobile devices seem feasible and acceptable in augmenting psychosocial interventions for severe mental illness, with future research in establishing efficacy, cost effectiveness, and ethical and safety protocols.
