Study Details

Study Description

Brief Summary

This study is a clinical trial that evaluates what drives patient engagement and tests the impact of two strategies-automated motivational push messaging and coach support-to improve engagement with an evidence-based mobile app intervention for depression and/or anxiety.

Condition or Disease	Intervention/Treatment	Phase
Depression Anxiety Disorders	Behavioral: IntelliCare Plus	N/A

Detailed Description

This 8-week, clinical trial involves primary care patients with clinically significant depression and/or anxiety recruited via provider referral. Participants will received access to a digital mental health intervention with known efficacy and be randomized to an engagement strategy condition--a previously-validated Coach Support protocol (CS), a newly-developed automated motivational messaging protocol (AMM), both or neither. To further understand how messages in the AMM arms function, message delivery will be micro-randomized: each day participants will be randomized to receive a message or not, such that they receive an average of 4.2 messages/week. Micro-randomization allows causal inference about the near-term impact of message delivery (i.e., are AMMs a cue to action) and the relationship between message impact and context (e.g., day in study). Measured outcome data will include level of engagement (operationalized as minutes of intervention use) and weekly self-reports of clinical outcomes.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: IntelliCare with Automated Motivational Messaging and Coach Support IntelliCare Plus mobile application intervention with two engagement strategies, automated motivational messaging and coach support.	Behavioral: IntelliCare Plus Mobile-app-based digital mental health intervention for individuals struggling with depression and/or anxiety. The app reflects components of evidence-based psychological treatments such as cognitive-behavioral therapy.
Experimental: IntelliCare with Automated Motivational Messaging IntelliCare Plus mobile application intervention with one engagement strategy, automated motivational messaging.	Behavioral: IntelliCare Plus Mobile-app-based digital mental health intervention for individuals struggling with depression and/or anxiety. The app reflects components of evidence-based psychological treatments such as cognitive-behavioral therapy.
Experimental: IntelliCare with Coach Support IntelliCare Plus mobile application intervention with one engagement strategy, coach support.	Behavioral: IntelliCare Plus Mobile-app-based digital mental health intervention for individuals struggling with depression and/or anxiety. The app reflects components of evidence-based psychological treatments such as cognitive-behavioral therapy.
Active Comparator: IntelliCare Alone IntelliCare Plus mobile application intervention with no additional engagement strategy applied.	Behavioral: IntelliCare Plus Mobile-app-based digital mental health intervention for individuals struggling with depression and/or anxiety. The app reflects components of evidence-based psychological treatments such as cognitive-behavioral therapy.

Outcome Measures

Primary Outcome Measures

Minutes of Intervention Use - Distal (Long-Term) [8-week intervention period]
Intervention use logs will be collected continuously and automatically throughout the intervention period on the system backend. Intervention engagement will be operationalized as minutes of active use over the intervention period.
Intervention Engagement Within 3 Hours Following a Decision Point - Proximal (Short-Term) [For 3 hours after each decision point, over the 8-week intervention period]
Intervention use logs will be collected continuously and automatically throughout the intervention period on the system backend. Proximal Intervention engagement will be operationalized as whether or not the intervention was used within 3 hours of a decision point (i.e., the point at which participants in the automated motivational messaging arms were randomized to receive or not receive an automated motivational message). This outcome only applies to participants randomized to receive automated motivational messaging.

Secondary Outcome Measures

Change in Patient Health Questionnaire-8 (PHQ-8) Self-Report Scale Score - Distal (Long-Term) [8-week intervention period]
The PHQ-8 is a self-report measure of severity of depressive symptoms. It will be used to determine the impact of the intervention on symptoms of depression.
Change in Generalized Anxiety Disorder-7 (GAD-7) Self-Report Scale Score - Distal (Long-Term) [8-week intervention period]
The GAD-7 is a self-report measure of severity of anxiety symptoms. It will be used to determine the impact of the intervention on symptoms of anxiety.
