Description

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.

Official Title

Mobile-assisted Cognitive Behavioral Therapy for Negative Symptoms in Schizophrenia: An RCT

Details

The primary purpose of this project is to determine if mCBTn at the optimal dose from the R61 produces greater reduction in severity of defeatist attitudes than a supportive contact control group in consumers with schizophrenia spectrum disorders with persistent moderate-to-severe experiential negative symptoms. A second aim is to determine whether reduction in defeatist attitudes mediates improvement in experiential negative symptoms and psychosocial functioning in mCBTn. The third aim is to determine whether mCBTn increases pupil dilation and whether changes in pupil dilation (an objective psychophysiological biomarker of effort) are associated with changes in defeatist attitudes and negative symptoms. The final aim is to explore predictors of response to mCBTn, including device use and group session adherence, demographics, neurocognitive impairment, and negative and other symptom severity at baseline.
