Brief Summary

This study is a validation study to evaluate the acceptability, feasibility and impact of a mobile psychosocial intervention to enhance social functioning in people with schizophrenia.

Detailed Description

The goal of this study is to employ an innovative and evidence-based mobile intervention that includes a neuroscience-informed computerized social cognition training program, a Health Insurance Portability and Accountability Act-compliant videoconferencing tool that we will use for psychoeducational group therapy, and peer-to-peer secure social networking for individuals with schizophrenia, in a parallel arm, double-blind, randomized, controlled clinical trial to assess feasibility and initial efficacy, to investigate the intervention's effects on symptoms, social cognition, and quality of life, and to prepare for a large-scale efficacy trial in adults with schizophrenia.

Primary Outcome Measures

Name	Time	Method
Quality of Life utilizing the Abbreviated Quality of Life Scale.	At 9 weeks	Between-group magnitude of change in quality of life utilizing the Abbreviated Quality of Life Scale. The Quality of Life Scale (QLS) is a scale commonly used as a measure of functioning in schizophrenia. The Abbreviated QLS (aQLS) includes 7 items representing all four interdependent theoretical constructs of the original 21-item QLS. Behavioral anchors are presented for each item, scored on a 0 (severe impairment) to 6 (high functioning) scale. Higher scores are indicative of greater quality of life.
Social Functioning utilizing the Social Functioning Scale.	At 9 weeks	Between-group magnitude of change in social functioning utilizing the Social Functioning Scale. The Social Functioning Scale (SFS) was constructed specifically to tap areas of social functioning that are crucial to the community maintenance of individuals with schizophrenia. The 7 domains include: social engagement/withdrawal, interpersonal behavior, pro-social activities, recreation, independence-competence, independence-performance, and employment/occupation. The raw scores for each domain are converted to scaled scores, with a mean of 100 and a standard deviation of 15. Higher scores are indicative of greater social functioning.
Negative Symptoms utilizing the Positive and Negative Syndrome Scale.	At 9 weeks	Between-group magnitude of change in negative symptoms utilizing the Positive and Negative Syndrome Scale. The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia. A rating from 1 to 7 is given to each of the 30 different symptoms. The 7-point rating represents increasing levels of psychopathology: 1= absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, and 7=extreme. Of the 30 items included in the PANSS, 7 constitute a Positive Scale, 7 a Negative Scale, and the remaining 16 a General Psychopathology Scale. The scores for these scales are arrived at by summation of ratings across component items. Therefore, the potential ranges are 7 to 49 for the Positive and Negative Scales, and 16 to 112 for the General Psychopathology Scale. Higher scores are indicative of greater symptomatology.
