A comparison of neurocognition and functioning in first episode psychosis populations: do research samples reflect the real world?

PURPOSE: The current study evaluates the demographic, clinical, and neurocognitive characteristics of a recruited FEP research sample, a research control group, and a FEP clinic sample that were assessed and treated within the same center and time period. METHODS: This study utilized data collected through an observational study and a retrospective chart review. Samples were ascertained in the Longitudinal Assessment and Monitoring of Clinical Status and Brain Function in Adolescents and Adults study and the Prevention and Recovery in Early Psychosis clinic. FEP clinic patients (n = 77), FEP research participants (n = 44), and age-matched controls (n = 38) were assessed using the MATRICS consensus cognitive battery and global functioning social and role scales. Between-group differences were assessed via one-way ANOVA and Chi-square analyses. RESULTS: No significant differences were observed between groups with regard to age and gender. The FEP research sample had a higher proportion of white participants, better social and role functioning, and better neurocognitive performance when compared with the FEP clinical population. The clinic sample also had more diagnostic variability and higher prevalence of substance use disorders relative to the FEP research sample. CONCLUSIONS: Researchers should be aware of how study design and recruitment practices may impact the representativeness of samples, with particular concern for equal representation of racial minorities and patients with more severe illness. Studies should be designed to minimize burden to promote a wider range of participation.

The impact of premorbid adjustment, neurocognition, and depression on social and role functioning in patients in an early psychosis treatment program.

OBJECTIVE: Functional impairments are debilitating concomitants of psychotic disorders and are present early in the illness course and, commonly, prior to psychosis onset. The factors affecting social and role functioning in early psychosis (EP) following treatment are unclear. We evaluated whether six months of participation in the PREP(R), Boston, EP treatment program, part of a public-academic community mental health center, was related to improvements in social and role functioning and whether premorbid adjustment in adolescence, baseline neurocognition, and depression symptoms predicted functional improvement. METHOD: The Global Functioning Social and Role scales, MATRICS neurocognitive battery, and Calgary Depression Scale were assessed at baseline and six months during naturalistic treatment, while premorbid adjustment was measured at baseline. All participants were psychotic disorder patients in PREP(R) (n = 46 with social functioning and 47 with role functioning measures at both time points). RESULTS: Large improvements were observed in role functioning (d = 0.84) and medium to large improvements were observed in social functioning (d = 0.70). Models consisting of adolescent premorbid adjustment and change in depression symptoms predicted social and role functioning change, whereas neuropsychological functioning did not. CONCLUSIONS: Substantial improvements in social and role functioning were observed among this sample participating in a recovery-based EP program. The impact of clinical factors on social and role functioning was highlighted. Further studies of premorbid adjustment in adolescence and the treatment of depression in EP programs in controlled treatment trials are needed to confirm these findings.

Longitudinal determinants of client treatment satisfaction in an intensive first-episode psychosis treatment programme.

AIM: Previous evidence demonstrates that higher treatment satisfaction is strongly associated with improved clinical outcomes and functioning. The aim of the current study is to explore potential associations between clinical and demographic attributes, as well as changes in role, social and cognitive functioning occurring over the course of treatment, on self-reported treatment satisfaction within the context of an intensive first-episode psychosis intervention programme. METHODS: Forty-four young adults attending a first-episode psychosis treatment programme completed a battery of clinical and neuropsychological measures at intake to the programme and again after 6 months of treatment. A modified version of the Client Satisfaction Questionnaire was administered at 6 months. Baseline, 6-month and change scores across the clinical and demographic measures were examined relative to the satisfaction questionnaire to evaluate determinants of treatment satisfaction. RESULTS: Better premorbid adjustment during childhood and early adolescence was associated with higher treatment satisfaction, as did positive changes in clients' cognitive performance and their use of humour as a coping strategy. Clients' use of emotional support as a coping strategy at 6 months was also positively associated with treatment satisfaction. Although clients' social and role functioning improved significantly during the 6-month treatment window, changes in functional outcomes were not significantly associated with treatment satisfaction. CONCLUSIONS: The current study highlights the role of premorbid adjustment and changes in coping and neurocognition as factors influencing treatment satisfaction. Future research designs might be able to more specifically ascertain causal relationships between patient characteristics, treatment components, client satisfaction and clinical effects.

Prevention and recovery in early psychosis (PREP(®)): building a public-academic partnership program in Massachusetts, United States.

Recently, there has been increasing emphasis on early intervention (EI) for psychotic disorders. EI programs in public mental health settings have been established in countries such as Australia, the United Kingdom, and Canada. However, there are relatively few EI programs in the United States (U.S.). Here we describe the conceptual origins and practical development of the PREP program, i.e., Prevention and Recovery in Early Psychosis, as it evolved in a public academic psychiatry setting in Boston, Massachusetts, U.S. PREP developed over a decade through a partnership between the Massachusetts Department of Mental Health and academic institutions within the Harvard Department of Psychiatry. We discuss the evolution, programmatic features, funding mechanisms, staffing, and the role of clinical training in PREP. The key principles in developing the PREP Program include the focus on early, evidence based, person-centered and phase-specific, integrated and continuous, comprehensive care. This program has served as a foundation for the emergence of related services at our institution, including a research clinic treating those at clinical high risk or within the putative "prodromal" period preceding frank psychosis. This account offers one possible blueprint for the development of EI programs despite the lack in the U.S. of a national mandate for EI or prevention-based mental health programs.
