Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We hypothesize that the use of a visual decision aid tool to educate patients regarding potential harm with respect to weight gain with olanzapine versus perphenazine can lead to better shared decision making by patients, increase rates of antipsychotic switches and promote weight loss in overweight patients with schizophrenia/schizoaffective disorder.

Our specific aims are the following:

1. To investigate the effects of a visual decision aid, versus care as usual, on patients' perceived difficulties in medical decision making regarding switching antipsychotics in overweight veterans with schizophrenia or schizoaffective disorder.
2. To investigate the effects of a visual decision aid and a shared decision making model on rate of medication switches (from olanzapine to perphenazine) in overweight veterans with schizophrenia or schizoaffective disorder.
3. To investigate the effects of a visual decision making aid and shared decision making model on BMI in overweight veterans who switch from olanzapine to perphenazine therapy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Visual Decision Making Aid

Shared decision-making, in contrast to traditional medical decision-making, involves a collaborative process where patients discuss personal values and preferences and clinicians provide information to arrive at an agreed upon treatment decision. The focus of the intervention is to empower overweight patients with schizophrenia/schizoaffective disorder and help them efficiently arrive at a treatment decision that can be successfully implemented.

Group Type EXPERIMENTAL

Visual Decision Aid and Shared Decision Making Model

Intervention Type BEHAVIORAL

Visual aid is a graph showing the average weight of patients who take olanzapine versus perphenazine over the course of 18 months. A script explaining the information on the graph, accompanies the graph. Patient may decide to stay on current dose of olanzapine, or be tapered off and prescribed a dose of perphenazine based on current symptoms and tolerability. Perphenazine (4-8mg ORALLY 3 times a day) will be used.

Usual Care

Usual care reflects the standard of care in psychiatry. Psychiatrists will recommend treatment for overweight patients with schizophrenia on olanzapine who have failed to lose weight despite life style and dietary modifications. They may recommend switching to a comparable antipsychotic with a lower incidence of weight gain.

Group Type ACTIVE_COMPARATOR

Usual Care

Intervention Type BEHAVIORAL

Usual care is standard clinical discussion and advice from a psychiatrist. Patient may decide to stay on current dose of olanzapine, or be tapered off and prescribed a dose of perphenazine based on current symptoms and tolerability. Perphenazine (4-8mg ORALLY 3 times a day) will be used.
