mHealth Behavior Study

Summary

The goal of this clinical trial is to learn if a brief task completed on a smartphone can reduce alcohol use and risky sexual behavior among women between the ages of 18 and 25 who have a history of experiencing sexual assault or an unwanted sexual experience. The main questions it aims to answer are:

* Does the smartphone task change approach biases for alcohol and condom-related images?
* Does the smartphone task reduce alcohol use and risky sexual behavior?

Researchers will compare the smartphone task to a sham control to see if the smartphone task changes biases and behavior.

Participants will:

* Complete a baseline assessment battery of questionnaires
* Complete either the intervention smartphone task or the sham smartphone task on four consecutive days.
* Complete a follow-up assessment one week after finishing the four tasks
* Complete a three-month follow-up

Conditions

• Alcohol Consumption
• Condom Use

Interventions

BEHAVIORAL

Training Group

Implicit approach bias is the behavioral action tendency to be faster to approach rather than avoid cues for a stimulus category. The Approach-Avoidance Task (AAT)is a computerized program in which participants make approach or avoidance movements in response to an irrelevant feature of an image presented on a computer screen (e.g., push when in portrait, pull when in landscape). The intervention in this study is a treatment version of the AAT used as an Approach Bias Modification (ABM) intervention, to retrain participants' implicit biases toward or away from stimuli by presenting the target stimuli predominantly in one format (e.g., push or pull).
