The goal of this study is to develop a machine-learning guided recovery messaging system. The main question it aims to answer is can messages be used to:
Participants will:
This study seeks to optimize messaging components which can be implemented in a recovery support messaging system such as may accompany a digital therapeutic app, in order to determine optimal messaging to increase interaction with recovery support resources, and whether messaging has any effect on clinical outcomes.

| Measure | Description | Time Frame |
|---|---|---|
| Participant engagement with the STAR system | Measured as days of engagement with the recovery system. | data collected at 2 and 4 months |
| Measure | Description | Time Frame |
|---|---|---|
| Number of heavy drinking days in the previous 28 days | Data collected via Timeline Followback (TLFB) conducted by interview at 0, 2, and 4 months. Ecological Momentary Assessment (EMA) lapse reports will be used to supplement the TLFB. These are daily surveys where the participant answers the question "have you had a drink you have not yet reported?" (Yes/No). If yes they are asked to indicate the date of their drinking and how many drinks they consumed that day (less than 1, 1-2, 3, 4, 5-6, 7-8, over 8). Four or more drinks are considered heavy drinking days for women and greater than 4 drinks are considered heavy drinking days for men. |

| data collected at baseline, 2, 4 months |
| Number of drinking days in the previous 28 days | Data collected via Timeline Followback (TLFB) conducted by interview at 0, 2, and 4 months. EMA lapse reports will be used to supplement the TLFB. These are daily surveys where the participant answers the question "have you had a drink you have not yet reported?" (Yes/No). If yes, they are asked to indicate the date of their drinking. | data collected at baseline, 2, 4 months |
| Flourishing Scale Score | 10 items rated on 0-10 Likert scale where lower scores represent worse functioning and higher scores represent better functioning. Total possible range of scores is from 0-100. | data collected at baseline, 2, 4 months |
| Generalized Anxiety Disorder-7 (GAD-7) Score | 7 items rated on 0-3 Likert scale where lower scores represent better functioning and higher scores represent worse functioning. Total possible range of scores is from 0-21. | data collected at baseline, 2, 4 months |
| Multidimensional Inventory of Recovery Capital (MIRC) Score: Total Score | 1-4 Likert scale. Some items are reverse coded but higher total scores represent better functioning and lower total scores represent worse functioning. Scored as total score 4-56. | data collected at baseline, 2, 4 months |
| Multidimensional Inventory of Recovery Capital (MIRC) Score: Each Domain | 1-4 Likert scale. Some items are reverse coded but higher total scores represent better functioning and lower total scores represent worse functioning. Scored in 4 domains (social, physical, human, and cultural), each from 1-14. | data collected at baseline, 2, 4 months |
| Patient Health Questionnaire (PQH-9) Score | 9 items rated on 1-4 Likert scale. Total possible range of scores from 0-27 where lower scores represent better functioning and higher scores represent worse functioning. | data collected at baseline, 2, 4 months |
| Digital Working Alliance Inventory (D-WAI) | Six items rated on 1-7 Likert scale. Scored in 3 domains (Goals, Tasks, Bonds, each with 2 items) with possible scores from 2 to 14 where higher scores represent greater alliance with the STAR system in that domain. | data collected at 2 and 4 months |
| Message Usefulness | Seven items rated on 1-7 Likert scale. Total possible scores from 7 to 49 where higher scores represent greater valuation of STAR message usefulness. | data collected at 2 and 4 months |
| Trust of the System | Ten items rated on 1-7 Likert scale. Total possible scores from 10 to 70 where higher scores represent greater trust in the STAR system. | data collected at 2 and 4 months |
