OBJECTIVE Schizophrenia (SZ) and Bipolar Disorder (BD) are associated with multidimensional disability. This study examined differential predictors of functional deficits between the disorders. METHODS Community dwelling individuals with SZ (N=161) or BD (N=130) were administered neuropsychological tests, symptom measures, performance-based social and adaptive (i.e., everyday-living skills) functional competence measures, and rated on domains of real-world functioning: 1) Community and Household activities, 2) Work skills, and 3) Interpersonal relationships. We used confirmatory path analysis to find the best fitting models to examine the direct and indirect (as mediated by competence) prediction of the three domains of real-world functioning. RESULTS In all models for both groups, neurocognition’s relationship with outcomes was largely mediated by competence. Symptoms were negatively associated with outcomes but unassociated with competence, with the exception of depression, which was a direct and mediated (through social competence) predictor in BD. In both groups, neurocognition was related to Activities directly and through a mediated relationship with adaptive competence. Work Skills were directly and indirectly (through mediation with social competence) predicted by neurocognition in SZ and entirely mediated by adaptive and social competence in BD. Neurocognition was associated with Interpersonal Relationships directly in the SZ group, and mediated by social competence in both groups. CONCLUSIONS Although there was greater disability in SZ, neurocognition predicted worse functioning in all outcome domains in both disorders. Our study supports the shared role of neurocognition in BD and SZ in producing disability, with predictive differences between disorders observed in domain-specific effects of symptoms and social and adaptive competence.

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.

Similar results were obtained for ACT and CBT. ACT seems to be a viable and effective treatment for dementia caregivers.

Objectives Neurocognitive deficits are common in bipolar disorder and contribute to functional disability. However, the degree to which general and specific cognitive deficits affect everyday functioning in bipolar disorder is unknown. The goal of this meta-analysis was to examine the magnitude of the effect of specific neurocognitive abilities on everyday functioning in bipolar disorder. Methods We conducted a comprehensive meta-analysis of studies that reported associations between performance on objective neuropsychological tasks and everyday functioning among individuals with bipolar disorder. From an initial pool of 486 papers, 22 studies met inclusion criteria, comprising a total of 1344 participants. Correlation coefficients were calculated for 11 cognitive domains and four measurement modalities for functioning. We also examined effect moderators, such as sample age, clinical state, and study design. Results The mean Pearson correlation between neurocognitive ability and functioning was 0.27, and was significant for all cognitive domains and varied little by cognitive domain. Correlations varied by methods of everyday functioning assessment, being lower for clinician and self-report than performance-based tasks and real-world milestones such as employment. None of the moderator analyses were significant. Conclusions Overall, the strength of association between cognitive ability and everyday functioning in bipolar disorder is strikingly similar to that seen in schizophrenia, with little evidence for differences across cognitive domains. The strength of association differed more so according to functional measurement approach.

In a short intervention, cognitive remediation produced robust improvements in neurocognition. Generalization to functional competence and real-world behavior was more likely when supplemental skills training and cognitive remediation were combined.

Objective To examine efficacy of a brief behavioral intervention to promote condom use among female sex workers (FSWs) in two Mexico-U.S. border cities. Methods 924 FSWs aged ≥18 years without known HIV infection living in Tijuana and Ciudad Juarez having recent unprotected sex with clients were randomized to a 30 minute behavioral intervention integrating motivational interviewing and principles of behavior change, or a didactic control condition. At baseline and six months, women underwent interviews and testing for HIV, syphilis, gonorrhea and chlamydia. Results Comparing intervention versus control groups, we observed a 40% decline in cumulative STI incidence (p=0.049). Incidence density for the intervention vs. control was 13.8 vs 24.92 per 100 person years (py) for STIs combined (p=0.034), and 0 vs. 2.01 per 100 py for HIV (p<0.001), with concomitant increases in total numbers and percentages of protected sex acts and decreases in total numbers of unprotected sex acts with clients (p<0.05). Conclusions This brief behavioral intervention shows promise in reducing HIV/STI risk behaviors among FSWs in two Mexican-U.S border cities, and may be transferable to other resource-constrained settings.

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.

Post-Traumatic Stress Disorder (PTSD) has major public health significance. Evidence that PTSD may be associated with premature senescence (early or accelerated aging) would have major implications for quality of life and healthcare policy. We conducted a comprehensive review of published empirical studies relevant to early aging in PTSD. Our search included the PubMed, PsycINFO and PILOTS databases for empirical reports published since the year 2000 relevant to early senescence and PTSD, including: (1) biomarkers of senescence (leukocyte telomere length (LTL) and pro-inflammatory markers), (2) prevalence of senescence-associated medical conditions, and (3) mortality rates. All six studies examining LTL indicated reduced LTL in PTSD (pooled Cohen’s d = 0.76). We also found consistent evidence of increased pro-inflammatory markers in PTSD (mean Cohen’s ds), including C-reactive protein = 0.18, Interleukin-1 beta = 0.44, Interleukin-6 = 0.78, and tumor necrosis factor alpha = 0.81. The majority of reviewed studies also indicated increased medical comorbidity among several targeted conditions known to be associated with normal aging, including cardiovascular disease, type 2 diabetes mellitus, gastrointestinal ulcer disease, and dementia. We also found seven of 10 studies indicated PTSD to be associated with earlier mortality (average HR = 1.29). In short, evidence from multiple lines of investigation suggests that PTSD may be associated with a phenotype of accelerated senescence. Further research is critical to understand the nature of this association. There may be a need to re-conceptualize PTSD beyond the boundaries of mental illness, and instead as a full systemic disorder.
