Using a Smartphone App to Target Current Mental Health Symptoms of Anxiety and Depression

March 11, 2025 updated by: Nicholas Jacobson, Trustees of Dartmouth College
This is a prevention intervention study that will examine the efficacy of a smartphone-based intervention in decreasing cancer risk by targeting mental health risk factors of anxiety and depression.

Intervention / Treatment

Detailed Description

This prevention intervention study aims to examine the efficacy of a smartphone-based intervention in decreasing cancer risk by targeting mental health risk factors of anxiety and depression. The study will utilize a smartphone application called Mood Triggers, designed to provide personalized feedback on individuals' maintenance factors (i.e., "triggers") of their anxiety and depressive symptoms. Mood Triggers delivers ultra-brief interventions (less than 2 minutes long) where participants view videos introducing important skills to treat their anxiety and depression. The study targets middle-aged adults (40-64 years old) who meet current criteria for moderate to severe anxiety and/or depressive disorders. It will enroll an anticipated 100 participants in a single-group, open-label design, with the intervention lasting up to 12 weeks. The primary outcomes include changes in depression and anxiety symptoms, measured by the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-Q-IV Scale, respectively, as well as changes in cancer risk assessed by the World Cancer Research Fund/American Institute for Cancer Research Cancer Prevention Score.

Intervention / Treatment
Experimental: MoodTriggers App
Mood Triggers provides personalized feedback on individuals' maintenance factors (i.e., "triggers") of their anxiety and depressive symptoms based on the theory that such feedback will lead to symptom reduction. Mood Triggers delivers ultra-brief interventions (less than 2 minutes long) where participants view videos which introduce an important skill to treat their anxiety and depressive.
The current intervention will deploy a smartphone application called Mood Triggers. Mood Triggers was designed to provide personalized feedback on individuals' maintenance factors (i.e., "triggers") of their anxiety and depressive symptoms based on the theory that such feedback will lead to symptom reduction.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in depression as assessed by Patient Health Questionnaire-9
Time Frame: Baseline
Possible PHQ-9 scores range from 0 to 27, with higher scores representing greater MDD symptom severity
Baseline
Changes in depression as assessed by Patient Health Questionnaire-9
Time Frame: 6 weeks post-baseline
Possible PHQ-9 scores range from 0 to 27, with higher scores representing greater MDD symptom severity.
6 weeks post-baseline
Changes in depression as assessed by Patient Health Questionnaire-9
Time Frame: 12 weeks post-baseline
Possible PHQ-9 scores range from 0 to 27, with higher scores representing greater MDD symptom severity
12 weeks post-baseline
Change in anxiety symptoms as assessed by Generalized Anxiety Disorder- Q-IV Scale
Time Frame: At baseline
Possible GAD-Q-IV scores range from 0 to 12, with higher scores representing greater GAD symptom severity
At baseline
Change in anxiety symptoms as assessed by Generalized Anxiety Disorder- Q-IV Scale
Time Frame: 6 weeks post-baseline
Possible GAD-Q-IV scores range from 0 to 12, with higher scores representing greater GAD symptom severity
6 weeks post-baseline
Change in anxiety symptoms as assessed by Generalized Anxiety Disorder- Q-IV Scale
Time Frame: 12 weeks post-baseline
Possible GAD-Q-IV scores range from 0 to 12, with higher scores representing greater GAD symptom severity
12 weeks post-baseline
World Cancer Research Fund (WCRF)/ American Institute for Cancer Research (AICR) Cancer Prevention Score.
Time Frame: Up to 12 weeks after enrollment
Minimum score: 0, Maximum score: 7-8 (8 for persons capable of breastfeeding). Greater scores suggest lower cancer risk.
Up to 12 weeks after enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Smartphone estimates of sociability as mechanisms of change in cancer risk
Time Frame: Up to 12 weeks after enrollment
Based on continuous passive mobile sensor data, sociability estimates will be based on the frequency of phone calls and texts.
Up to 12 weeks after enrollment
Smartphone estimates of motion activity as mechanisms of change in cancer risk
Time Frame: Up to 12 weeks after enrollment
Based on both activity levels based on the metabolic equivalent of task (MET) based on passively observed accelerometer data from the smartphone and daily movement based on geolocation data passively collected from the smartphone.
Up to 12 weeks after enrollment
Diet as mechanism of change in cancer risk
Time Frame: Baseline, 6 weeks post-baseline, 12 weeks post-baseline
Self-reported dietary intake will be recorded via entry of food intake in ASA24 and used when calculating WCRF/AICR cancer score. Diets rich in nutrients contribute to higher score (lower risk).
Baseline, 6 weeks post-baseline, 12 weeks post-baseline
Momentary Assessment of Anxiety Symptom Changes
Time Frame: Up to 12 weeks after enrollment
Thirteen items from a modified PHQ/GAD questionnaire will be used to measure daily anxiety and depression. Participants will rate answers on a 101 point scale ranging from 0-100 and is scaled from "Not at all" - "Constantly". Higher scores indicate generally more severe anxiety symptoms.
Up to 12 weeks after enrollment
Momentary Assessment of Depression Symptom Changes
Time Frame: Up to 12 weeks after enrollment
Thirteen items from a modified PHQ/GAD questionnaire will be used to measure daily anxiety and depression. Participants will rate answers on a 101 point scale ranging from 0-100 and is scaled from "Not at all" - "Constantly". Higher scores indicate generally more severe MDD symptoms.
Up to 12 weeks after enrollment
Momentary Assessment of Behavioral Avoidance Symptom Changes
Time Frame: Up to 12 weeks after enrollment
One item adapted from the Multidimensional Experiential Avoidance Questionnaire will be presented to measure daily changes in behavioral avoidance. A second item will be asked to measure self-reported changes in behavioral avoidance since the previous prompt.
Up to 12 weeks after enrollment
Momentary Assessment of Hopelessness Symptom Changes
Time Frame: Up to 12 weeks after enrollment
One item adapted from the Hopelessness Scale will be presented to gather a momentary measurement. A second momentary measurement will be presented to gather current self-report of feeling hopelessness.
Up to 12 weeks after enrollment
Momentary Assessment of Arousal Symptom Changes
Time Frame: Up to 12 weeks after enrollment
A self-report measure will ask current level of arousal on a sliding scale from "Sleepy" to "Active". Minimum or maximum values range from 0 (Sleepy) to 1 (Active).
Up to 12 weeks after enrollment
