Objective

Identifying treatments to improve functioning and reduce negative symptoms in consumers with schizophrenia is of high public health significance.

Method

In this randomized clinical trial, participants with schizophrenia or schizoaffective disorder (N = 149) were randomly assigned to cognitive behavioral social skills training (CBSST) or an active goal-focused supportive contact (GFSC) control condition. CBSST combined cognitive behavior therapy with social skills training and problem-solving training to improve functioning and negative symptoms. GFSC was weekly supportive group therapy focused on setting and achieving functioning goals. Blind raters assessed functioning (primary outcome: Independent Living Skills Survey [ILSS]), CBSST skill knowledge, positive and negative symptoms, depression, and defeatist performance attitudes.

Results

In mixed-effects regression models in intent-to-treat analyses, CBSST skill knowledge, functioning, amotivation/asociality negative symptoms, and defeatist performance attitudes improved significantly more in CBSST relative to GFSC. In both treatment groups, comparable improvements were also found for positive symptoms and a performance-based measure of social competence.

Conclusions

The results suggest CBSST is an effective treatment to improve functioning and experiential negative symptoms in consumers with schizophrenia, and both CBSST and supportive group therapy actively focused on setting and achieving functioning goals can improve social competence and reduce positive symptoms.

This study examined stakeholder perceptions of the fit between cognitive-behavioral social skills training (CBSST) and assertive community treatment (ACT) when implementing CBSST into existing community-based ACT teams. Focus group feedback was collected from a diverse set of stakeholders (i.e., clients, providers, supervisors, agency administrators, public sector representatives, and intervention developers). Results identified perceived client and provider benefits for integrating CBSST into ACT while highlighting the importance of purposeful adaptations, training, and implementation tools to facilitate structural and values fit between CBSST and ACT. Study findings will inform future endeavors to implement CBSST and other relevant EBPs into ACT. Trial Registry: ClinicalTrials.gov #NCT02254733.

Background

Schizophrenia leads to profound disability in everyday functioning (e.g., difficulty finding and maintaining employment, housing, and personal relationships). Medications can effectively reduce positive symptoms (e.g., hallucinations and delusions), but they do not meaningfully improve daily life functioning. Psychosocial evidence-based practices (EBPs) improve functioning, but these EBPs are not available to most people with schizophrenia. The field must close the research and service delivery gap by adapting EBPs for schizophrenia to facilitate widespread implementation in community settings. Our hybrid effectiveness and implementation study represents an initiative to bridge this divide. In this study we will test whether an existing EBP (i.e., Cognitive Behavioral Social Skills Training (CBSST)) modified to work in practice settings (i.e., Assertive Community Treatment (ACT) teams) commonly available to persons with schizophrenia results in better consumer outcomes. We will also identify key factors relevant to developing future CBSST implementation strategies.

Methods/design

For the effectiveness study component, persons with schizophrenia will be recruited from existing publicly funded ACT teams operating in community settings. Participants will be randomized to one of the 2 treatments (ACT alone or ACT + Adapted CBSST) and followed longitudinally for 18 months with assessments every 18 weeks after baseline (5 in total). The primary outcome domain is psychosocial functioning (e.g., everyday living skills and activities related to employment, education, and housing) as measured by self-report, testing, and observation. Additional outcome domains of interest include mediators of change in functioning, symptoms, and quality of services. Primary analyses will be conducted using linear mixed-effects models for continuous data. The implementation study component consists of a structured, mixed qualitative-quantitative methodology (i.e., Concept Mapping) to characterize and assess the implementation experience from multiple stakeholder perspectives in order to inform future implementation initiatives.

Discussion

Adapting CBSST to fit into the ACT service delivery context found throughout the United States creates an opportunity to substantially increase the number of persons with schizophrenia who could have access to and benefit from EBPs. As part of the implementation learning process training materials and treatment workbooks have been revised to promote easier use of CBSST in the context of brief community-based ACT visits.

Schizophrenia is a major cause of disability worldwide. As new treatments for functioning are tested, the need grows to demonstrate real-world functioning gains. Ecological momentary assessment (EMA) may provide a more ecologically valid measure of functioning. In this study, smartphone-based EMA was used to signal participants with schizophrenia (N = 100) and controls (N = 71) 7 times a day for 7 days to respond to brief questionnaires about social interactions and functioning behaviors. Excellent adherence was found, with both groups completing an average of 85% of surveys and only 3% of participants with schizophrenia excluded for poor adherence. Four-week test-retest reliability was high (r = .83 for total productive behaviors). Relative to controls, participants with schizophrenia reported significantly less total productive activity (d = 1.2), fewer social interactions (d = 0.3), more nonproductive behaviors (d = 1.0; watching TV, resting), and more time at home (d = 0.8). Within the schizophrenia group, participants living independently showed better functioning on EMA relative to participants in supported housing (d = 0.8) and participants engaged in vocational activities showed better functioning than individuals not engaged in vocational activities (d = 0.55). Modest correlations were found between EMA and an in-lab self-report measure of functioning activities performed in the community, but not between EMA and measures of functional capacity or potential. This study demonstrated the feasibility, sensitivity reliability, and validity of EMA methods to assess functioning in schizophrenia. EMA provides a much-needed measure of what individuals with schizophrenia are actually doing in real-world contexts. These results also suggest that there may be important disjunctions between indices of abilities and actual real-world functioning.

Background

The hypothesis that defeatist performance attitudes are associated with decreased goal-directed task effort and negative symptoms in consumers with schizophrenia was investigated by using pupillary responses as a biomarker of task effort. Pupillary dilation during cognitive tasks provides a biomarker of effort devoted to the task, with greater dilation indicating greater effort.

Methods

Defeatist attitudes were assessed in 149 consumers with schizophrenia or schizoaffective disorder and 50 healthy control subjects, and consumers were divided into three groups (tertile split) with respect to severity of defeatist attitudes. Pupillary dilation responses were recorded during a digit-span task with three-, six-, and nine-digit spans.

Results

Effort allocation (pupillary responses) to the task increased as the processing load increased from low (three-digit) to moderate (six-digit) demands in healthy control subjects and consumers with schizophrenia with mild and moderate severity of defeatist attitudes. In contrast, consumers with severe defeatist attitudes did not increase their effort when processing demands increased from low to moderate loads. These consumers showed significantly less effort in the six-digit condition relative to consumers with mild defeatist attitudes. Moreover, consumers with severe defeatist attitudes showed significantly greater severity of negative symptoms relative to consumers with mild defeatist attitudes and negative symptoms were significantly correlated with defeatist attitudes.

Conclusions

These results suggest a relationship between defeatist performance attitudes, goal-directed task effort indexed by pupillary responses, and negative symptoms in schizophrenia. The findings have implications for using cognitive therapy to reduce defeatist attitudes that may contribute to diminished effort and negative symptoms in schizophrenia.

Objectives

To determine whether Cognitive Behavioral Social Skills Training (CBSST) is an effective psychosocial intervention to improve functioning in older consumers with schizophrenia, and whether defeatist performance attitudes are associated with change in functioning in CBSST.

Design

An 18-month, single-blind, randomized controlled trial.

Setting

Outpatient clinic at a university-affiliated Veterans Affairs hospital.

Participants

Veteran and non-veteran consumers with schizophrenia or schizoaffective disorder (N = 79) age 45-78.

Interventions

CBSST was a 36-session, weekly group therapy that combined cognitive behavior therapy with social skills training and problem-solving training to improve functioning. The comparison intervention, goal-focused supportive contact (GFSC), was supportive group therapy focused on achieving functioning goals.

Measurements

Blind raters assessed functioning (primary outcome: Independent Living Skills Survey), CBSST skill mastery, positive and negative symptoms, depression, anxiety, defeatist attitudes, self-esteem, and life satisfaction.

Results

Functioning trajectories over time were significantly more positive in CBSST than in GFSC, especially for participants with more severe defeatist performance attitudes. Greater improvement in defeatist attitudes was also associated with better functioning in CBSST, but not GFSC. Both treatments showed comparable significant improvements in amotivation, depression, anxiety, positive self-esteem, and life satisfaction.

Conclusions

CBSST is an effective treatment to improve functioning in older consumers with schizophrenia, and both CBSST and other supportive goal-focused interventions can reduce symptom distress, increase motivation and self-esteem, and improve life satisfaction. Participants with more severe defeatist performance attitudes may benefit most from cognitive behavioral interventions that target functioning.

With recent developments in medical and psychiatric research surrounding pupillary response, cheap and accessible pupillometers could enable medical benefits from early neurological disease detection to measurements of cognitive load. In this paper, we introduce a novel smartphone-based pupillometer to allow for future development in clinical research surrounding at-home pupil measurements. Our solution utilizes a NIR front-facing camera for facial recognition paired with the RGB selfie camera to perform tracking of absolute pupil dilation with sub-millimeter accuracy. In comparison to a gold standard pupillometer during a pupillary light reflex test, the smartphone-based system achieves a median MAE of 0.27mm for absolute pupil dilation tracking and a median error of 3.52% for pupil dilation change tracking. Additionally, we remotely deployed the system to older adults as part of a usability study that demonstrates promise for future smartphone deployments to remotely collect data in older, inexperienced adult users operating the system themselves.

AIM: Difficulties in social functioning have been observed in youth at clinical high-risk (CHR) of psychosis even in those who do not go on to develop a psychotic illness. Few treatment studies have attempted to improve social functioning in this population. The aim of this study was to conduct a randomized trial comparing the effects of Cognitive-Behavioral Social Skills Training (CBSST) with a supportive therapy (ST). METHODS: Both CBSST and ST were weekly group therapies, delivered over 18 weeks. This was a 2-arm trial with single-blinded ratings and intention-to-treat analyses. Assessments occurred at baseline, end-of-treatment, and 12 months after the baseline assessment. The primary outcome was social and role functioning and defeatist performance attitudes were the secondary outcome. Attenuated positive and negative symptoms, anxiety, depression, self-efficacy, and beliefs about self and others were examined as exploratory outcomes. RESULTS: There were no significant differences between the 2 groups at baseline or either of the 2 follow-ups. However, at follow-ups, in each group there were significant improvements in clinical symptoms. These could not be attributed to group treatment since there was no control or wait-list group. CONCLUSIONS: Since poor social functioning is one of the most observed difficulties in CHR individuals, and a decline in social functioning may be a significant predictor of later transition to psychosis, future work will be needed to find effective treatments for this decline in functioning for CHR youth.

This study aimed to identify factors associated with implementation of cognitive behavioral social skills training (CBSST) on assertive community treatment (ACT) teams in a large public sector behavioral health system. This study used concept mapping (a mixed-method approach) and involved a sample including diverse stakeholder participants including patients, ACT team members, team leaders, organization leaders, and system leaders. We identified 14 distinct issues related to implementing CBSST on ACT teams: (a) CBSST fit with ACT structure, (b) CBSST fit with ACT process, (c) provider perceptions about CBSST, (d) staff pressures/other demands; (e) CBSST and ACT synergy, (f) client characteristics, (g) benefits of CBSST, (h) coordination/interaction among ACT providers, (i) government/regulatory factors, (j) integration of CBSST into ACT, (k) training support, (l) training resources, (m) multilevel agency leadership, and (n) provider characteristics. Each of these dimensions were rated in regard to importance and changeability with the top 5 rated dimensions including effective training support; alignment of leadership across levels of the community-based organizations delivering services; perceived benefits of CBSST, CBSST and ACT synergy; and provider perceptions of CBSST. The most critical issues for CBSST implementation on ACT teams should be addressed in future studies. Implementation strategies that capitalize on enhancing leadership and organizational climate hold promise to address all of these issues.

Objective

Negative 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.

Methods

Fifty-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.

Results

Mixed-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.

Conclusions

CBSST-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.
