Not Applicable

Completed

• Conditions: Schizophrenia; Schizoaffective Disorder
• Interventions: Behavioral: Treatment as usual

• Registration Number: NCT01952041
• Lead Sponsor: Dartmouth-Hitchcock Medical Center

Brief Summary

This study was a 2-arm randomized control trial (RCT) designed to test a multi-modal smartphone data collection system that provided mobile monitoring of schizophrenia to detect early signs of relapse. The RCT compared an arm with participants who received treatment as usual with an arm that received the smartphone system for a year.

Arm && Interventions

Group	Intervention	Description
Treatment as Usual	Treatment as usual	Treatment as usual included outpatient case management, linkage to services and medication monitoring.

Primary Outcome Measures

Name	Time	Method
Relapses in Participants	1 year	A count of participants who experienced relapse, as defined as one of the following events: psychiatric hospitalization, a significant increase in the level of psychiatric care (i.e. frequency and intensity of services), an increase in medication in addition to a 25% increase in Brief Psychiatric Rating Scale (BPRS) from last assessment, suicidal or homicidal ideation that was clinically significant in the investigator's judgement, deliberate self-injury, violent behavior resulting in damage to another person or property.
Time to Relapse	From randomization date until first relapse (evaluated approximately every 3 months until their last study visit which occurred approximately 12 months from randomization for those who completed the study).	Time to first relapse was defined as the time from randomization until the first relapse. Participants who did not experience a relapse were censored at their last known time relapse-free. Time-to-first relapse was estimated using the Kaplan-Meier method.

Secondary Outcome Measures

Name	Time	Method
Depression	Assessed at baseline and every three months for one year.	Depression measured using the Calgary Depression Scales (CDSS). This is a 9-item assessment with values of 0 (absent) to 3 (severe) of depressive symptoms separate from positive, negative and extrapyramidal symptoms in people with schizophrenia. Total scores range from 0-27. A higher score indicates more severe symptoms.
Social Functioning	Assessed at baseline and every three months for one year.	Social Functioning was assessed using the Social Functioning Scale (SFS). This is a 76-item questionnaire that assesses various aspects of social functioning and generates a number of subscale scores including social withdrawal, interpersonal behavior, pro-social activities, and an overall score of social functioning. The item values range from 0 (almost never) to 3 (often). Total scores range from 0-228. A higher score indicates greater social functioning.
Psychotic Symptom Severity	Assessed at baseline and every three months for one year.	Psychotic symptom severity assessed using the Brief Psychiatric Rating Scale (BPRS). This is an 18-item scale that rates severity of positive symptoms (including auditory hallucinations and persecutory ideation), and mood and behavioral symptoms. Items are rated by a clinical assessor on a scale of 1 (absent) to 7 (very severe). Total scores range from 18-126. Higher scores indicate worse symptoms.
