Real-Time Mobile Cognitive Behavioral Intervention for Serious Mental Illness

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effectiveness of a mobile real-time cognitive behavioral intervention for serious mental illness (SMI) and to identify the facilitators, barriers, and costs of implementation. We would like to determine whether the addition of a mobile phone monitoring software program to a brief behavioral intervention for bipolar disorder or schizophrenia improves symptoms arising from the disorders. In this study we will be assessing the feasibility, acceptability and short term effect of the mobile phone enhanced intervention for bipolar disorder and schizophrenia.

Detailed Description
-----------------
Bipolar disorder (BD) and Schizophrenia (SZ) are leading causes of disability and are the costliest disorders to treat among serious mental illnesses. Ample evidence exists that evidence-based psychotherapies such as cognitive behavioral therapy (CBT) produce clinically significant improvements in symptoms of BD and SZ, and yet only 5% of patients in the community can access these treatments. Access to CBT for serious mental illnesses is limited by the restricted pool of trained providers, the resource intensity of these treatments, and cessation of reimbursement for psychological services in many public mental health systems. Our research in BD and SZ over the past five years indicates that mobile phones can provide automated yet personalized cognitive behavioral intervention that is feasible, acceptable, and associated with improvements in symptoms, medication adherence and socialization. Our intervention, called CBT2go, integrates ecological momentary assessment with personalized interventions delivered in the moment that symptoms and related experiences occur. We have developed an innovative platform that functions on various screen types, operating system, or data access technologies, and we have begun to incorporate innovative features into CBT2go, including location-based data and personalized predictive modeling, that can potentially lead to transformative mobile interventions. We propose a research study with the overarching aims of evaluating the effectiveness of CBT2go, gathering necessary data to refine its innovative features, and examining its costs, facilitators, and barriers to implementation in a public mental health system. We propose a randomized controlled trial with three arms: 1) CBT2go, 2) an ecological momentary assessment only condition to control for self-monitoring and device contact, and 3) standard care. A total of 255 participants with either BD or SZ will be recruited from a large public mental health system that has minimal access to CBT. Participants will be assessed at baseline, 6 weeks (mid-treatment), 12 weeks (post-treatment) and 24 weeks (follow-up). The primary outcome of the study will be clinician rated global psychopathology, and secondary outcomes will include medication adherence, social functioning, and mental health service utilization. Recognizing that not all participants will benefit, we propose to examine differential effectiveness in sub-groups. We will also examine mechanisms of change to inform mobile intervention design, focusing on the impact of CBT2go on cognitive insight and dysfunctional attitudes, which are two mediators of change in traditionally delivered CBT. Drawing from experience in implementation research, we will employ a mixed methods approach to assessing the facilitators, barriers, and costs of adoption of CBT2go from perspectives of consumers, technology experts, administrators and front-line clinicians. This study will lay the groundwork for CBT2go to be adapted and implemented with high fidelity in healthcare settings.

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: CBT2go<br>Participants assigned to this condition will attend one session with a therapist to identify cognitive and behavioral strategies around four areas: 1) mood/psychotic symptoms, 2) medication adherence, 3) socialization, and 4) relapse prevention. Subsequently they will answer questions on a mobile device (smartphone) 3 times per day for 12 weeks, and they will receive personalized cognitive and behavioral strategies linked to their momentary responses with bi-monthly telephone support. | Behavioral: CBT2go<br>* CBT administered using mobile intervention.<br>Device: Smartphone<br>* A smartphone platform will be used to deliver the CBT2go behavioral intervention and the surveys in the EMA-only arm.<br>|
| Active Comparator: EMA-only<br>Participants assigned to this condition will answer questions on a mobile device (smartphone) 3 times per day for 12 weeks but will not receive personalized cognitive and behavioral strategies. | Device: Smartphone<br>* A smartphone platform will be used to deliver the CBT2go behavioral intervention and the surveys in the EMA-only arm.<br>|
| No Intervention: Standard Care<br>Participants assigned to this condition will only participate in the assessments. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Score on the Brief Psychiatric Rating Scale (BPRS) | The BPRS-24 includes 24 items that cover depression, anxiety, mania, suicidality, delusions/hallucinations, and unusual behavior. The BPRS is reliable, valid, and sensitive to change in both bipolar disorder and schizophrenia, and therefore enables the examination of diagnosis as a moderator of treatment effect. Twenty four items are rated on a 1-7 scale from present to severe, and the Total Score will be the primary outcome for analyses. It is clinician rated and the minimum score is 24 and the maximum score is 148 and higher scores reflect worse outcome. | Baseline, 6 weeks, 12 weeks, and 24 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| SPECIFIC LEVEL OF FUNCTION (SLOF) | The SLOF is an interviewer rated measure that addresses community function in serious mental illness, utilizing a best estimate approach in which data is integrated from interviewer, informant, and participant responses. The score ranges from 30 to 150. Higher scores equal greater function. | Baseline, 12 weeks, 24 weeks |
