Shared Decision Making for Antipsychotic Medications

March 24, 2026 updated by: Lisa Dixon, New York State Psychiatric Institute

Examining the Effectiveness of a Shared Decision Making Intervention for Antipsychotic Medications to Improve Engagement in Treatment for People Experiencing Early Psychosis

This study aims to provide an evidence-based shared decision making intervention for antipsychotic medications, the Antipsychotic Medication Decision Aid (APM-DA), for individuals experiencing early psychosis and provide, for the first time, an understanding of the shared decision making mechanism of action.

Study Overview

Detailed Description

The investigators will conduct a cluster RCT of the APM-DA intervention at 6 OnTrackNY clinics, with 3 clinics implementing APM-DA as part of their psychiatric visits and 3 randomized to serve as control offering treatment as usual (TAU). The planned sample size is 120 OnTrackNY clients with first episode psychosis (FEP). This real-world pilot cluster RCT will assess the feasibility of the APM-DA intervention in FEP care, providing the first evidence for the effectiveness of the APM-DA compared with TAU and understanding of the SDM intervention's mechanism of action.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: The Antipsychotic Medication Decision Aid (APM-DA) intervention clinics
Three pairs of comparable clinics (out of 22 clinics where OnTrackNY operates) based on the same region of the state and similar numbers of patients with similar demographic composition. One of each paired clinic is assigned to the intervention group by a blinded Co-I who will generate binary random variables.
The APM-DA intervention is the first and only International Patient Decision Aid Standards (IPDAS) approved shared decision making (SDM) decision aid intervention for Antipsychotic Medication decisions in psychiatric visits. The APM-DA intervention developed by the research team addresses a common issue among psychiatric care providers and patients that lies in the heart of pharmacotherapy - taking, tapering or stopping APM. The APM-DA has a print format and can be used online as a PDF. It includes a concise table describing what each option involves, its benefits, risks, and strategies to reduce risks. The intervention was developed in co-production with various stakeholders (patients, clinicians, service leadership, family members, researchers). Additional intervention materials are an evidence document to support the information and an APM side effects table.
No Intervention: Treatment As Usual (TAU) clinics
The other clinic of each of the three pairs will be assigned to TAU.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The 9-item Shared Decision Making Questionnaire for Psychiatry (SDM-Q-9-Psy) (Primary)
Time Frame: Change in SDM from baseline (T0, measured after the first medication visit) to the next post medication visit/s (Tnext) and up to a period of 3 months follow-up (T2)
The 9-item Shared Decision Making Questionnaire for Psychiatry (SDM-Q-9-Psy) is the only validated self-report measure for SDM in psychiatry/mental health. The SDM-Q-9-Psy includes 9 items ranging from 0 to 5, with higher scores indicating higher quality of the SDM process perceived by the patient. The SDM-Q-9-Psy will be first measured (baseline, T0) after the first medication visit and then after each medication visit throughout the study period, therefore there will be multiple post-visits or "Tnext".
Change in SDM from baseline (T0, measured after the first medication visit) to the next post medication visit/s (Tnext) and up to a period of 3 months follow-up (T2)
Intent to Attend and Complete Treatment Scale (Primary)
Time Frame: Change in OnTrackNY engagement from baseline (T0, measured at enrollment), after each post medication visit/s (Tnext), and at 3-month follow-up (T2 )
The Intent to Attend and Complete Treatment are two items that are part of the EPINET Core Assessment Battery (CAB) "Medication Side Effects and Treatment Adherence" core domain to assess engagement in CSC program (OnTrackNY). The score ranges from 0 to 9 for each item, with higher scores indicating higher intent to attend and complete treatment. Changes in the Intent to Attend will be measured after each medication visit throughout the study period, therefore there will be multiple post-visits or "Tnext".
Change in OnTrackNY engagement from baseline (T0, measured at enrollment), after each post medication visit/s (Tnext), and at 3-month follow-up (T2 )
Adherence Estimator (Primary)
Time Frame: Change in Adherence Estimator from baseline (T0, measured at enrollment), after each post-visit/s (Tnext), and at 3-month follow-up (T2 )
The Adherence Estimator is a three-item measure relies on client self-report. The Adherence Estimator focuses on perceived concerns about medications, perceived need for medications, and perceived affordability of medications. The Adherence Estimator is scored by adding up the total number of points in each item and can range from 0 (Low risk for adherence problems) to 36 (High risk for adherence problems). Changes in the Adherence Estimator will be measured after each medication visit throughout the study period, therefore there will be multiple post-visits or "Tnext".
Change in Adherence Estimator from baseline (T0, measured at enrollment), after each post-visit/s (Tnext), and at 3-month follow-up (T2 )
