|Condition or disease||Intervention/treatment||Phase|
|Schizophrenia Bipolar Disorder Depression Psychotic Disorders||Drug: aripiprazole; fluoxetine; bupropion; sertraline; lamotrigine Behavioral: Psychoeducational multifamily group treatment Behavioral: Supported employment and education||Not Applicable|
The study is structured as a cutoff, regression discontinuity design, in which lower risk-for-psychosis participants will not be treated by protocol but followed up for two years. Those at higher risk will be treated with anti-psychotic, antidepressant and mood stabilizing medications by symptom indications, and systematically provided psychoeducational multifamily group treatment, supported education and employment, and intensive clinical case management, using key elements of Assertive Community Treatment. Both arms of the study will be followed for two years and assessed at 6, 12, and 24 months. Outcome measures include rates of conversion to psychosis, relapse of psychosis, development of psychotic disorder diagnoses, levels of positive, negative and general symptoms, social and vocational functioning, family functioning, and neurocognitive functioning.
The six sites include Sacramento, California; Salem Oregon; and surrounding counties, Ypsilanti and Washtenaw County, Michigan; Portland, Maine; Albuquerque, New Mexico and Glen Oaks, New York.
In addition to symptomatic and functional outcomes, impact on incidence of psychotic disorders, including schizophrenia, will be assessed, as will cost-benefit effects.

- Psychotic Symptoms [ Time Frame: two years ]Psychotic symptoms were assessed and scored using the Structured Interview for the Prodromal Syndrome (SIPS) and the Scale of Prodromal Symptoms (SOPS). The SOPS provides a measure of four domains of symptoms, including positive, negative, disorganized and general symptoms. The Positive Symptom sub-scale score reported is the sum of all five symptom items in the Positive Symptom sub-scale. The Positive Symptom sub-scale assesses psychotic symptoms, each item on a scale of 0-6. The sum scale score is 0-30, with 30 indicating severe psychotic symptoms, while 0 indicates no psychotic symptoms.
