Brief Summary
This randomized controlled clinical trial will test a combined group contact plus mobile CBT-informed skills training intervention targeting defeatist attitudes in consumers with schizophrenia in comparison to a supportive contact control group in order to change motivational negative symptoms linked to defeatist attitudes.

Outcome Measures
Primary Outcomes (2)
Defeatist performance beliefs (target mechanism) using the Defeatist Performance Attitude Scale
Measure changes in defeatist performance beliefs severity using the Defeatist Performance Attitude Scale (DPAS). The DPAS is a 5-minute, 15-item self-report subscale derived from factor analysis of the commonly-used 40-item Dysfunctional Attitude Scale, which measures the tendency to overgeneralize from past failure experiences and form defeatist beliefs about the ability to perform future goal-directed tasks. Items are rated on a 1-7 Likert scale. A total score is reported with a range of 7 - 105 with higher total scores indicating more severe defeatist performance attitudes.
Assess change from baseline in defeatist performance beliefs at weeks 9, 18, and 42.
Clinical Assessment Interview for Negative Symptoms (CAINS)
Measure changes in motivational negative symptoms on the CAINS. The CAINS is a 13-item interview-based assessment of negative symptoms, and each item is rated from 0 (no impairment) to 4 (severe deficit) measuring the two negative symptom factors recommended in consensus reports: Expression and Motivation and Pleasure (MAP) across social, vocational and recreational domains. Total scores for each factor are computed. The range for the MAP is 0 - 36, and the range for the Expression factor is 0 - 16. Higher scores indicate more severe negative symptoms for both factors.
Assess change from baseline in negative symptoms at weeks 9, 18, and 42.
Secondary Outcomes (2)
Pupillary responses as effort biomarker
Assess change from baseline in pupil dilation at weeks 9, 18, and 42.
Birchwood Social Functioning Scale (SFS)
Assess change from baseline in functioning at weeks 9, 18, and 42.
Study Arms (2)
Mobile-assisted CBT-informed Skills Training
EXPERIMENTALPsychosocial intervention combining in-person and smartphone-based CBT-informed skills training for experiential negative symptoms in schizophrenia, called Mobile-assisted Cognitive-Behavioral Therapy for Negative symptoms (mCBTn).
Supportive Contact
PLACEBO COMPARATORAn active group leader- and device-contact control group.
Interventions
mCBTn combines the CBT-informed components that target defeatist attitudes from Cognitive Behavioral Social Skills Training (CBSST) group skills training and mobile smartphone interventions from our prior clinical trials research.
The SC intervention will provide the same amount of group and mobile device contact as the mCBTn condition. Participants will be carrying a phone but will not have access to the CBT-informed app. Group contact sessions will be semi-structured and consist of trouble-shooting device use and check-in about symptoms and potential crisis management, followed by a flexible discussion involving psychoeducation, instructions for accessing community crisis lines and related community resources, empathy, and non-directive reinforcement of health, coping, and symptom management behaviors that grow out of group discussions, with only minimal group leader guidance.
Eligibility Criteria
You may qualify if:
- DSM-5 diagnosis of schizophrenia or schizoaffective disorder.
- Meets prospective criteria for persistent moderate-to-severe experiential negative symptoms in at least two of the three CAINS Motivation and Pleasure domains (mean of 2 -moderate- or greater for items averaged within the Social, Work or Recreational domains) at the beginning and end of a 2-week evaluation phase.
- Moderate-to-severe defeatist attitudes (DPAS \> 50).
- ≥ 6th grade reading level on the Wide Range Achievement Test-4 Reading subtest (needed for reading treatment manual consumer workbook).
You may not qualify if:
- Prior CBT in the past 2 years.
- Greater than moderate PANSS positive symptoms (P1-Delusions, P2- Disorganization, P3-Hallucinations, or P6-Suspiciousness - any item \>5).
- Severe depression on the Calgary Depression Scale for Schizophrenia (CDS \>8).
- Extrapyramidal symptoms.
- Ocular damage, disease, surgery or medications that affect pupil dilation.
- DSM-5 alcohol or substance use disorder in past 3 months.
- Level of care required interferes with outpatient skills training (e.g., hospitalized; severe medical illness).
- Unable to adequately see or manually manipulate the mobile device.
