Brief summary
This project is an effectiveness trial comparing two psychosocial treatments for schizophrenia: Assertive Community Treatment (ACT) + Cognitive Behavioral Social Skills Training (CBSST) v. ACT, alone.
Detailed description
Assertive community treatment (ACT) is one of the most well-validated treatment models for people with severe mental illness, and ACT is one of the few evidence-based practices that is widely implemented in community mental health programs; however, existing ACT approaches have little impact on functioning. The ACT model provides a unique opportunity for implementation of recovery-oriented EBPs throughout community mental health programs in the US. This project will examine the incremental effectiveness of implementing cognitive-behavioral strategies and social skills training in ACT relative to ACT, alone. The investigators will begin to examine a potential mechanism of change involving defeatist performance beliefs that can interfere with performance of community functioning behaviors, and will use qualitative methods to identify barriers and factors that contribute to successful implementation.
Interventions
CBSST integrates CBT and SST techniques and neurocognitive compensatory aids. The treatment manual includes a patient workbook that describes the skills and includes homework assignment forms. Cognitive therapy is combined with role play practice of communication skills and problem-solving training. The ACT-adapted, team-delivered individual CBSST intervention will be delivered in 3 6-session modules (Cognitive Skills, Social Skills, and Problem Solving Skills) for a total of 18 weekly individual therapy sessions, but with participants completing the sequence of 3 modules twice, for a total of 36 sessions (9 months).
Assertive Community Treatment model is a evidence based practice model. ACT teams are multi-disciplinary and provide comprehensive services to individuals in their natural setting with small staff to recipient ratio. ACT teams use assertive engagement to proactively engage individuals in treatment providing services and support directly to individuals that are tailored to meet their specific goals and needs.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Independent Living Skills Survey (ILSS) | Baseline, 18 mos. | The ILSS is 70 item self-report measure in an interview format to assess everyday functioning. Each item is rated from 0 (No) to 1 (Yes). Scales are summed to yield a total score. Higher scores represent a higher level of functioning. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Scale for Assessment of Negative Symptoms (SANS) | Baseline, 18 mos. | The SANS is a 25 item semi-structured clinical interview designed to assess negative symptoms. The first 13 items measure diminished expression which consists of two domains: Affective flattening and Alogia. Each item is rated from 0 (Absent) to 5 (Severe). The total score is derived from the average of the Affective Flattening and Alogia global ratings (items #8 and #13) |
| Defeatist Performance Attitude Scale (DPAS) | Baseline, 18 mos. | The DPAS is a 15-item self-report subscale of the commonly-used 40-item Dysfunctional Attitude Scale (DAS) used to measure generalized defeatist beliefs about one's ability to perform tasks and effectiveness of social behaviors. Each item is rated from 1 (agree completely) to 7 (disagree completely). Higher total scores (range = 15-105) indicate more severe defeatist performance attitudes. |
| Maryland Assessment of Social Competence (MASC) | Baseline, 18 mos. | The MASC is a structured behavioral role play assessment that measures the ability to resolve interpersonal problems through conversation in three role play scenarios. Videotaped role plays are rated by blinded raters on three dimensions; verbal content, nonverbal communication behavior, and overall effectiveness, which will be the primary MASC variable. Each item is rated from 1 (very poor) to 5 (very good). A higher score for that dimension reflects higher ability and skills to solve problems in an interpersonal context. |
| Expanded Brief Psychiatric Rating Scale (BPRS) - Positive symptom factor structure | Baseline, 18 mos. | The expanded BPRS is a 24-item scale that measures psychiatric symptom severity. Each item is rated from 1 (not reported) to 7 (very severe). Items are summed to yield a total factor score. Higher scores represent higher positive symptom severity. |
| Cognitive Therapy Scale for Psychosis (CTS-Psy) | Baseline, 18 mos | The Cognitive Therapy Scale for Psychosis (CTS-Psy) is 10 item scale for assessing the quality of cognitive behavior therapy. Items are scored on a scale from 0 to 6, where the total maximum achievable is 60. Higher scores indicate greater level of competency. |
| Dartmouth Assertive Community Treatment Scale (DACTS) | Baseline, 18 mos | The DACTS is an assessment of assertive community treatment service fidelity. It consists of 28 items, each rated on a behaviorally-anchored scale from 1(not implemented) to 5 (fully implemented). The mean score for the total scale will be used as the measure of ACT team fidelity. A DACTS score of \>4.0 is considered moderately high fidelity. |
| Comprehensive Modules Test (CMT) | Baseline, 18 mos. | The Comprehensive Module Test (CMT) is an assessment of CBSST skills acquisition. Scores are summed to yield a total CMT score range from 0-33. Higher total scores represent higher level of CBSST skills acquisition. |
