Summary

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.

Conditions

• Schizophrenia
• Schizoaffective Disorder

Interventions

Type	Name	Description
BEHAVIORAL	Visual Decision Aid and Shared Decision Making Model	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.
BEHAVIORAL	Usual Care	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.
