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.

Possible PHQ-9 scores range from 0 to 27, with higher scores representing greater MDD symptom severity

Possible PHQ-9 scores range from 0 to 27, with higher scores representing greater MDD symptom severity.

Possible GAD-Q-IV scores range from 0 to 12, with higher scores representing greater GAD symptom severity

Minimum score: 0, Maximum score: 7-8 (8 for persons capable of breastfeeding). Greater scores suggest lower cancer risk.

Based on continuous passive mobile sensor data, sociability estimates will be based on the frequency of phone calls and texts.

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.

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).

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.

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.

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.

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).

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.
