The Efficacy of Using a Smartphone App to Support Shared Decision Making in People With a Diagnosis of Schizophrenia

The Momentum Trial: The Efficacy of Using a Smartphone Application to Support Shared Decision Making Through Patient Activation in People With a Diagnosis of Schizophrenia in Outpatient Treatment Settings

This study investigates the effects of using a smartphone app to support shared decision making (SDM) for people with schizophrenia-spectrum disorders in an outpatient treatment setting. Patients are randomized to specialized early intervention treatment with the Momentum app or without the app. The primary objective is to investigate the effect of the app on patient activation 6 months after baseline. Secondary outcomes are positive and negative symptoms, level of functioning; working alliance; self-efficacy; treatment satisfaction; hope; level of SDM; and perceived efficacy in patient-provider interaction. Explorative outcomes are self-perceived usefulness of the Momentum app.

Study Overview

• Status: Completed
• Conditions: Schizophrenia, Schizotypal and Delusional Disorders
• Intervention / Treatment: Device: Momentum app

Detailed Description

Background:

Shared decision making (SDM) may be associated with positive health outcomes for the patient. While practitioners provide a professional expertise with information on the diagnosis, course of the illness, treatment options and potential side effects, patients are experts on their own needs, treatment preferences and goals. In mental healthcare, SDM have been assessed as a promising treatment intervention to promote patient involvement and clinical guidelines advocate the use of SDM as a patient-centered mental health care and a mean to increase patient empowerment. Although SDM today seems to be a preferred model for clinical decision-making for both patients and providers in mental health, patients indicate that they are not involved as much as they want to be in their treatment. Studies on SDM interventions for people with mental health issues are somewhat sparse and due to a small number of RCT studies, the evidence on SDM in mental health has been concluded as encouraging but inconclusive.

Based on recent research, a digital healthcare solution which links patients and providers together could assist in providing support and potentially promote SDM. Findings from existing randomized controlled trials suggest that electronic aids to support SDM are a promising mean to engage patients in their mental health treatment. Recent systematic reviews do, however, highlight a need for more evidence-based research on the efficacy and effectiveness of mental health apps.

Intervention:

Momentum is a smartphone app, developed to support people with schizophrenia-spectrum disorders to prepare for treatment consultations while becoming more involved in treatment decisions. The app was developed in the period of 2013-2014 to support SDM in the Mental Health Services of the Capital Region of Denmark in a process of co-creation. Afterwards, the app was tested by 116 mental health professionals and 78 patients from three different mental health treatment sites: community of mental health, inpatient- and outpatient treatment sites. The app has since then been optimized based on the feedback received from the study participants.

Aim:

The purpose of this trial is to investigate the effects of the smartphone app Momentum for people with a diagnosis of schizophrenia, schizotypal or delusional disorders within outpatient treatment settings in a randomized design. Our main hypothesis is that patients using the Momentum app in combination with receiving specialized early intervention treatment (i.e. treatment as usual (TAU)), compared to patients only receiving TAU, will show greater improvements in patient activation, 6 months after baseline (primary outcome). Our secondary hypothesis is that patients using the Momentum app in combination with receiving TAU, compared to patients only receiving TAU, will show greater improvements regarding self-perceived level of SDM; self-efficacy; the therapeutic alliance; hope and optimism; satisfaction with treatment; patient's confidence in communicating preferences and concerns to their provider; severity of symptoms and; level of functioning (secondary outcomes). Lastly, the investigators hypothesize that there is a correlation between the effects of using the Momentum app and self-reported usefulness of the Momentum app and/or app usage (user sessions per day, screen views per day, screens per session, session duration and session instances, user retention) (explorative outcomes).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention: Momentum app; Intervention Group will receive treatment as usual together with the Momentum app.	Device: Momentum app; The Momentum system consists of a smartphone app (for the patient) and a web portal (for the provider). Information entered in the app by the patient will automatically be transferred to the web portal for the provider to see. While one goal of the system is to support SDM, the Momentum app is not a classic decision aid focusing on finding a choice to a one-off treatment decision. Instead, the Momentum app is an aid to support some of the underlying elements behind SDM such as collaboration with one's provider, awareness and eliciting of one's needs, preferences and values.
No Intervention: Control; Control Group will receive treatment as usual without the Momentum app.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in patient activation measured with the Consumer Health Activation Index - Mental Health (CHAI-MH)	Completed by patients. The 10-item instrument was developed based on 5 key domains: knowledge, self-efficacy, motivation and beliefs, actions, and internal locus of control. The questionnaire is rated on a 6-point Likert scale ranging from "Strongly disagree" to "Strongly agree". Afterwards, the scores are transformed into a theoretical value from 0 to 100, with higher scores signifying a stronger involvement in the treatment and confidence in the ability to take care of one's own health and health treatment.	baseline, 3 months and end of intervention (6 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in self-efficacy measured with the General Self-Efficacy scale (GSE)	Completed by patients. The questions consists of 10 items rated on a 4-point Likert scale ranging from "not at all true" (1) to "exactly true" (4) with higher scores indicating higher self-efficacy.	baseline, 3 months and end of intervention (6 months)
Change in preparedness for decision making measured with the scale Preparation for Decision Making (PrepDM)	Completed by patients. The 10-item instrument measures the patient's perception of how useful a decision aid or other decision support intervention is.

Change in the efficacy of interactions measured with the scale Perceived Efficacy in Patient-Provider Interactions (PEPPI)	Completed by patients. The 5-item instrument measures the assessment of patient's confidence in communicating with their physician. The questionnaire is rated on a 10-point Likert scale, with higher scores indicating higher perceived efficacy in the interactions	baseline, 3 months and end of intervention (6 months)
Change in treatment satisfaction measured with the Client Satisfaction Questionnaire (CSQ)	Completed by patients. The 8-item instrument measures a patient's satisfaction with treatment.

The questionnaire is rated on a 5-point Likert scale with higher scores indicating a higher desire by the clinician for active service user participation in decision making and to provide information to the service user.	baseline
Service Engagement Scale - Collaboration sub-domain only (SES)	Completed by providers. The scale is a 14-item measurement for the provider to rate their patient's engagement level on the subscale Collaboration. Each item is scored on a 4 point Likert scale, with higher scores indicating poorer engagement.	baseline and 6 months
Change in positive symptoms measured by the Scale for the Assessment of Positive Symptoms (SAPS)	Each dimension within SAPS is scored between 0-5 with higher scores indicating higher symptom severity	baseline and 6 months
