Completed

• Conditions: Mood Disorder, Psychotic; Schizophrenia; Schizoaffective Disorder
• Interventions: Behavioral: mobile Social Interaction Therapy by Exposure (mSITE)

• Registration Number: NCT05660070
• Lead Sponsor: University of California, San Diego

Brief Summary

This open trial will test a new technology-supported blended intervention, mobile Social Interaction Therapy by Exposure (mSITE), that targets social engagement in consumers with serious mental illness.

Detailed Description

Social isolation is common in serious mental illness and has a profound negative impact on recovery. This study evaluates a new technology-supported blended intervention, mobile Social Interaction Therapy by Exposure (mSITE), that targets social behavior, and it also validates several new techniques for measuring social behavior. mSITE blends brief in-person psychotherapy with context-triggered mobile smartphone intervention and remote telephone coaching. The investigators will conduct an open trial of mSITE, evaluating whether the intervention leads to clinically significant changes in the frequency of social interactions. The investigators will also determine the dose of app plus remote coaching necessary to achieve this effect, by evaluating change at 12, 18, or 24 weeks. If found to be effective, a scalable intervention that reduces social isolation in serious mental illness would have significant personal, societal, and economic impact.

Primary Outcome Measures

Name	Time	Method
Birchwood Social Functioning Scale	Assess change from baseline in social functioning at Weeks 0, 8, 12, 18, and 24	Measure changes in functioning on the Birchwood Social Functioning Scale (SFS). The SFS is a self-report assessment of functioning with 7 subscales, and each item is rated from 0 to 3 with the exception of the Occupation/Employment subscale if a participant is in regular employment (scores range from 7-10 based upon type of work). The subscales and score ranges are: Social Engagement Withdrawal (0-15), Interpersonal Communication/Relationships (0-30), Prosocial Activities (0-66), Recreation (0-48), Independence-Performance (0-39), Independence-Competence (0-39), and Occupation/Employment (0-10). Higher scores indicate better functioning for all subscales.
Ecological Momentary Assessment	Assess change from baseline in number of social interactions at Weeks 0, 8, 12, 18, and 24	EMA is a method of remote data collection that involves repeatedly sampling a participant's current behaviors, thoughts, mood, and experiences in real time, in their natural environments. The primary outcome in this study will be the number of social interactions.
Passive sensing mobile application	Assess change from baseline in number of conversations at Weeks 0, 8, 12, 18, and 24	The passive sensing mobile application will measure the number of conversations. The conversations or specific content will not be recorded.
Clinical Assessment Interview for Negative Symptoms	Assess change from baseline in expression and motivation and pleasure at Weeks 0, 8, 12, 18, and 24	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.
Positive And Negative Syndrome Scale	Assess change from baseline in positive and negative symptoms at Weeks 0, 8, 12, 18, and 24	The PANSS is a 30-item interview that provides balanced representation of positive and negative symptoms and gauges their relationship to one another and to global psychopathology. Items are rated 1 (Absent) to 7 (Extreme) and summed across items for a total range of scores of 30-210. Higher scores indicate the presence of more severe symptoms.
