This research study aims to evaluate the feasibility, safety, and effectiveness of a micro-randomized acceptance and commitment therapy-based (ACT-based) intervention that is delivered to distressed first-generation college students.
The transition to college is associated with a number of changes in health behaviors and mental health functioning, with 50% of college students meeting criteria for a psychiatric disorder. In particular, first-generation college students may be at particular risk for increased stress and mental health difficulties. The development of effective psychotherapeutic interventions is essential in providing adequate care to young adults during the transitional years of college. Delivery of these interventions via acceptable and feasible modalities for this population is also of utmost importance so that utilization and engagement are prioritized. Brief interventions have been a point of emphasis in recent years from the perspective of patient and provider efficiency, as well as many studies indicating effectiveness of brief interventions in creating and sustaining clinical levels of change. The current study seeks to evaluate the effectiveness of brief interventions delivered via a smartphone app, or "microinterventions", based in Acceptance and Commitment Therapy (ACT). ACT is a cognitive-behavioral therapy that seeks to promote psychological flexibility. ACT is transdiagnostic, meaning that it is designed to target human suffering, rather than a particular psychological or physical disorder. ACT targets experiential avoidance, which is the inability or unwillingness to make contact with painful experiences (e.g., thoughts, emotions, memories. Avoidance provides short-term relief, but exacerbates the long-term experience of the avoided stimulus in terms of intensity and duration. The microintervention in this study will consist of one of 84 prompts that aim to target one of 6 processes targeted in ACT. For example, one prompt is "Do your current actions align with what matters most to you?" Delivery of these prompts (e.g., whether and when to deliver which prompt) is randomized to allow for secondary analyses of optimal delivery of the microintervention in addition to primary analyses of its effectiveness.

The mobile intervention in this study consists of two components: 1) self-monitoring and 2) an ACT-based microintervention. Self-monitoring: twice daily, participants will complete self-reports of distress, depressive symptoms, and activity through the mobile app Lorevimo. Microintervention: The microintervention will consist of one of 84 prompts that aim to target one of 6 processes targeted in ACT (contacting the present moment, defusion, acceptance, self-as-context, values, and committed action). At each time-point, participants have a 50% chance of receiving a microintervention question along with the daily self-monitoring assessments.

Feasibility of the ACT micro-intervention: percentage adherence to PHQ-2, PSS-4, and activity prompts
The feasibility of the microintervention will be assessed by Adherence to prompts (defined as a response to at least 50% completion of prompt items per day). If subjects adhere to prompts over 60% of the days of the intervention period on average, the intervention will be considered feasible. The prompts considered will be the 2 questions from the PHQ-2, the 4 questions from the PSS-4, and the 4 questions from the activity assessment.
Time frame: Day 1 - day 43
Safety of ACT micro-intervention: Change in Patient Health Questionnaire 9 (PHQ-9)
The analysis will look at the change in proportion of individuals who meet criteria for minor or major depression on the PHQ-9 between study start (measure taken at baseline assessment) to study end (measure taken at 6-month follow-up assessment). The Patient Health Questionnaire 9 (PHQ-9) is a multipurpose scale for screening, diagnosing, monitoring and measuring the severity of depression. PHQ-9 will reflect the effect of intervention on the severity of depression. The PHQ-9 scores correlates with the depression severity as follows: 5 to 9- Minimal symptoms 10 to 14- Minor depression 15 to 19 Major depression, moderately severe \>20 Major depression, severe
Time frame: Baseline, 3 months and 6 months post intervention
Effectiveness of the ACT micro-intervention: proximal changes in mood outcomes as a result of intervention as indicated by self-reported activity of participant
The effectiveness of the ACT micro-intervention will be assessed by looking at the responses to the activity assessment in relation to whether or not a participant received a micro-intervention at the prior time-point. The activity questions of interest are as follows: 1. Since you \[woke this morning or last logged your symptoms\], how much energy was consumed by trying to get rid of unwanted feelings, thoughts, or other internal experiences (example: suppressing, distracting, avoiding)? 2. Since you \[woke this morning or last logged your symptoms\], how much energy was consumed by pursuing your values (example: making choices that align with who you want to be or who/what matters)? Both questions are answered using a scale of 0-6, where 0 = "none" and 6 = "all of my energy."

Proximal changes in mood outcomes as a result of intervention: The Perceived Stress Scale (PSS-4) score
The effectiveness of the ACT micro-intervention will be assessed by looking at the PSS-4 score in relation to whether or not a participant received a micro-intervention at the prior time-point. The Perceived Stress Scale (PSS-4) consists of four questions, each answered using a scale of 0-4. The total PSS-4 score ranges from 0-16. A higher score indicates a higher degree and/or longer duration of perceived stress.
Time frame: Days 1-43
Proximal changes in mood outcomes as a result of intervention: Patient Health Questionnaire-2 (PHQ-2) score
The effectiveness of the ACT micro-intervention will be assessed by looking at PHQ-2 score in relation to whether or not a participant received a micro-intervention at the prior time-point. The PHQ-2 consists of the first two questions of the Patient Health Questionnaire-9 (PHQ-9) and asks about the frequency of depressed mood and anhedonia over the past two weeks. Each question is answered on a scale of 0-3 as follows: 0 = Not at all 1. = Several days 2. = More than half the days 3. = Nearly every day The PHQ-2 score ranges from 0-6, with a score of 0-2 being negative for potential major depressive disorder and a score of 3 or more being positive for potential major depressive disorder.
