mHealth Behavior Study

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
