A comparison of compensatory and restorative cognitive interventions in early psychosis.

ABSTRACT: This randomized trial examined the relative effectiveness of primarily compensatory and primarily restorative cognitive interventions in an early psychosis population. A total of 56 patients were randomized to one of two treatments which were applied for four months with a five month follow up assessment. Comparisons were between (1) Cognitive Adaptation Training (CAT) - a treatment that uses environmental supports and weekly home visits to compensate for cognitive challenges and improve community functioning and (2) Action Based Cognitive Remediation (ABCR) - a treatment involving computerized cognitive drill and practice exercises, simulations, goal setting, and behavioral activation. Linear mixed effects models demonstrated significant effects on community functioning for both CAT and ABCR without a difference between conditions (n?=?39), with an indication of greater gains at follow up in the ABCR group (n?=?31). Improvements in symptomatology were less robust with mixed findings across neurocognition metrics. This study concluded that both CAT and ABCR hold promise as interventions for early intervention psychosis populations but more work is needed to identify illness severity, subtype and contextual considerations that might indicate an emphasis on more compensatory versus more restorative cognitive interventions.

Project description:ObjectiveCognitive compensatory interventions aim to alleviate psychosocial disability by targeting functioning directly using aids and strategies, thereby minimizing the impact of cognitive impairment. The aim was to conduct a systematic review and meta-analysis of cognitive compensatory interventions for psychosis by examining the effects on functioning and symptoms, and exploring whether intervention factors, study design, and age influenced effect sizes.MethodsElectronic databases (Ovid Medline, PsychINFO) were searched up to October 2018. Records obtained through electronic and manual searches were screened independently by two reviewers according to selection criteria. Data were extracted to calculate estimated effects (Hedge's g) of treatment on functioning and symptoms at post-intervention and follow-up. Study quality was assessed using Cochrane Collaboration's risk of bias tool.ResultsTwenty-six studies, from 25 independent randomized controlled trials (RCTs) were included in the meta-analysis (1654 participants, mean age = 38.9 years, 64% male). Meta-analysis revealed a medium effect of compensatory interventions on functioning compared to control conditions (Hedge's g = 0.46, 95% CI = 0.33, 0.60, P < .001), with evidence of relative durability at follow-up (Hedge's g = 0.36, 95% CI = 0.19, 0.54, P < .001). Analysis also revealed small significant effects of cognitive compensatory treatment on negative, positive, and general psychiatric symptoms, but not depressive symptoms. Estimated effects did not significantly vary according to treatment factors (ie, compensatory approach, dosage), delivery method (ie, individual/group), age, or risk of bias. Longer treatment length was associated with larger effect sizes for functioning outcomes. No evidence of publication bias was identified.ConclusionCognitive compensatory interventions are associated with robust, durable improvements in functioning in people with psychotic illnesses.

Project description:ObjectiveNegative symptoms and cognitive impairment in schizophrenia (SZ) remain unmet treatment needs as they are highly prevalent, associated with poor functional outcomes, and resistant to pharmacologic treatment. The current pilot randomized controlled trial examined the efficacy of an integrated Cognitive-Behavioral Social Skills Training and Compensatory Cognitive Training (CBSST-CCT) intervention compared to Goal-focused Supportive Contact (SC) on negative symptoms and cognitive performance.MethodsFifty-five adults with SZ or schizoaffective disorder with moderate-to-severe negative symptoms were randomized to receive 25 twice-weekly, 1-h manualized group sessions (12.5 weeks total duration) of either CBSST-CCT or SC delivered by master's level clinicians in five community settings. Assessments of negative symptom severity (primary outcomes) and neuropsychological performance, functional capacity, social skills performance, and self-reported functional ability/everyday functioning, psychiatric symptom severity, and motivation (secondary outcomes) were administered at baseline, mid-treatment, post-treatment, and 6-month follow-up.ResultsMixed-effects models using baseline, mid-treatment, and post-treatment data demonstrated significant CBSST-CCT-associated effects on negative symptom severity, as assessed by the Scale for the Assessment of Negative Symptoms (p = .049, r = 0.22), with improvements in diminished motivation driving this effect (p = .037, r = 0.24). The CBSST-CCT group also demonstrated improved verbal learning compared to SC participants (p = .026, r = 0.36). The effects of CBSST-CCT appeared to be durable at 6-month follow-up.ConclusionsCBSST-CCT improved negative symptom severity and verbal learning in high-negative-symptom individuals relative to SC. CBSST-CCT warrants larger investigations to examine its efficacy in treating negative symptoms, along with other symptoms, cognition, and, ultimately, real-world functional outcomes.

Project description:Background: Early psychosocial interventions targeting cognitive and functional outcomes in individuals at clinical high risk for psychosis are a research priority. An even greater need is the identification of effective interventions in underserved populations. Compensatory Cognitive Training (CCT) is a psychosocial intervention with demonstrated efficacy in chronic schizophrenia and first episode psychosis, but remains to be evaluated in pre-illness phases. The aim of this study was to describe the development and implementation of an ongoing pilot randomized controlled trial investigating the efficacy of group-based, manualized CCT, as compared to recreational therapy (RT), for Latino participants at clinical high risk for psychosis (CHR) in both the United States and Mexico. It is hypothesized that, in comparison to those receiving RT, participants receiving CCT will show significant improvements in neurocognitive performance and functional capacity (co-primary outcomes) and self-rated functioning and clinical symptoms (secondary outcomes). Methods: Latino CHR participants aged 12-30 years will be included in the study. Both CCT and RT will be delivered in either Spanish or English, depending on group preference. Additionally, all assessments will be administered in participants' preferred language. A comprehensive assessment of neurocognitive and functional performance and clinical symptomatology will be performed at baseline, mid-intervention (4 weeks, 8 weeks), post-intervention (12 weeks) and 3-month follow-up. The primary outcome measures are neurocognition and functional capacity, as assessed by the MATRICS (Measurement and Treatment Research in Cognition in Schizophrenia) Consensus Cognitive Battery and the University of California, San Diego Performance-Based Skills Assessment-Brief, respectively. Furthermore, secondary outcomes measures will be used to examine change in clinical symptoms and self-reported functioning in response to CCT versus RT. Discussion: The evaluation of a novel treatment such as CCT in CHR youth will provide empirical support for a low risk, comprehensive cognitive intervention that could have important implications for public health if it improves neurocognition and functioning.

Project description:Family interventions for psychosis (FIp) are effective in reducing service user relapse and carer distress in people with schizophrenia-spectrum conditions. Several treatment and best practice guidelines recommend FIp for all people with schizophrenia. However, outcome findings in relation to early psychosis groups have been inconsistent. The current paper reports a systematic review and meta-analyses of articles that evaluated FIp in early psychosis with a clearly defined comparison group. A combination of electronic database searches (using PsychINFO, Medline, and CENTRAL), citation searches and hand searches of key journals and reviews was conducted. Peer-reviewed articles published in English from database inception to June 2016 were included. Methodological quality was assessed using the Effective Public Health Practice Project Quality Assessment Tool (EPHPP). Seventeen papers from 14 studies met inclusion criteria for review, the overall quality of which was moderate. Meta-analytic synthesis showed that FIp improved service user functioning and reduced the likelihood of relapse by the end of treatment. Psychotic symptoms were significantly reduced in the FIp group at follow up, but this was not evident at end of treatment. In terms of FIp target mechanisms, carers receiving FIp were more likely to shift from high to low expressed emotion and less likely to report patient focused criticism or engage in conflict communication than carers randomized to standard care. Carer burden and well-being were improved by the end of treatment but gains were not sustained at follow up. FIp had no impact on carer emotional over-involvement. The findings indicate that FIp is an effective intervention for early psychosis service users and their relatives. However, further research is required to establish which key therapeutic components of FIp are most effective for whom, in addition to understanding the mechanisms by which FIp might affect positive change.

Project description:ImportanceMost patients with psychotic disorders experience severe cognitive impairment, but the onset and course of this impairment remain unclear. Moreover, the course of cognitive functions in other psychiatric conditions remains largely unexamined.ObjectiveTo chart the course of general and specific cognitive functions in individuals with psychotic disorders, psychotic experiences, and depression.Design, setting, and participantsThe Avon Longitudinal Study of Parents and Children (ALSPAC) is a prospective cohort study comprising all live births between April 1, 1991, and December 31, 1992, in Avon, England. The dates of analysis were September 2015 to July 2016. Participants who underwent cognitive testing at ages 18 months and 4, 8, 15, and 20 years and psychiatric assessment at age 18 years were included.Main outcomes and measuresIndividuals with psychotic disorder, psychosis with depression, psychotic experiences, and depression were compared with controls. Outcomes were full-scale, verbal, and nonverbal IQ at ages 18 months and 4, 8, 15, and 20 years, as well as measures of processing speed, working memory, language, visuospatial ability, and attention at ages 8 and 20 years.ResultsThe following numbers of individuals were available for analyses in this longitudinal birth cohort study: 511 (238 male [46.6%]) at age 18 months (mean [SD] age, 1.53 [0.03] years), 483 (229 male [47.4%]) at age 4 years (mean [SD] age, 4.07 [0.03] years), 3930 (1679 male [42.7%]) at age 8 years (mean [SD] age, 8.65 [0.29] years), 3783 (1686 male [44.6%]) at age 15 years (mean [SD] age, 15.45 [0.27] years), and 257 (90 male [35.0%]) at age 20 years (mean [SD] age, 20.06 [0.55] years). Individuals with psychotic disorder showed continually increasing deficits between infancy (18 months) and adulthood (20 years) in full-scale IQ (effect size of change [ESΔ] = -1.09, P = .02) and nonverbal IQ (ESΔ = -0.94, P = .008). The depression group showed a small, increasing deficit in nonverbal IQ (ESΔ = -0.29, P = .04) between infancy and adulthood. Between ages 8 and 20 years, the psychotic disorder group exhibited developmental lags (ie, slower growth) in measures of processing speed (ESΔ = -0.68, P = .001), working memory (ESΔ = -0.59, P = .004), and attention (ESΔ = -0.44, P = .001) and large, static deficits in measures of language (ES = -0.87, P = .005) and visuospatial ability (ES = -0.90, P = .001). There was only weak evidence for cognitive deficits in the psychosis with depression group and the psychotic experiences group.Conclusions and relevanceThe findings herein suggest that the origins of psychotic disorder involve dynamic developmental processes, affecting both verbal and nonverbal abilities throughout the first 2 decades of life and leading to increasing dysfunction. These developmental processes do not manifest in other psychiatric disorders, such as psychosis with depression and depression.
