Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project aims to create a comprehensive data repository by collecting survey and smartphone data from adults who have used drugs or alcohol. Participants will use the TTRU-Curtis AWARE app to provide digital phenotyping data, which includes smartphone usage, social media interactions, and sensor measurements. The goal is to analyze this data to uncover behavioral patterns and risk factors associated with substance use, ultimately informing prevention and intervention strategies. Data collection will occur over a period of up to six months, with all activities conducted online.

Why it matters

Who can join: the full rules

* INCLUSION CRITERIA:

In order to be eligible to participate in the repository, an individual must meet all of the following criteria:

* Must understand and be willing to complete an online informed consent process.
* Be an adult aged 18 or older.
* Self-report alcohol or other drug use within the past 30 days.
* Have a smartphone as their primary mobile phone.

  --For the AWARE app data monitoring procedure, there may be times during this study period where, due to technical or OS limitations, the app is only available to users of certain devices (e.g., Android, iOS). If there is such a limitation, this information will be evaluated during screening. For example, if the AWARE app is not available for iOS, then the screening form may exclude iPhone users for that time period where the limitation exists, if the only procedures offered are daily diary surveys and AWARE data monitoring.
* Be willing to adhere to the procedures, such as downloading the AWARE app onto their smartphone and keeping it active throughout the data collection period, completing baseline questionnaires, daily diary EMAs, open-ended survey questions with the TTR Chatbot, uploading historical conversational AI data, and/or follow-up surveys.
* Understand and write in English.

  --This exclusion criterion is included because future research on the data collected will include linguistic analysis. all linguistic analyses, we remove rare words (e.g., words must be said by at least 95% of participants)95. Additionally, there are cultural differences across languages and, thus, interpreting language results across more than one language becomes difficult.96 As a result, we must keep analysis limited to a single language (English), since words in other languages will not meet that criteria.
* Live in the United States.

EXCLUSION CRITERIA:

An individual who meets any of the following criteria will be excluded from participation in this repository:

1\. Any impairment severe enough to preclude informed consent or valid self-report.
