Informational App Development for mHealth for Patient Self-Management of Opioid Use Disorder (KIOS-I)

The University of Texas Health Science Center at San Antonio, National Institute on Drug Abuse (NIDA)

This study will evaluate the feasibility of an app that provides drug information to people in recovery from opioid use disorder. This study is designed to test the prototype app, not to determine health outcomes. The study will confirm the design and operating specifications prior to being evaluated in a larger clinical trial.

The overall study is designed in two steps: 1) a one-week proof-of-concept study; and 2) a one-month pilot study. Step 1: A one-week proof-of-concept study will be performed in a small population (n=5) of individuals in opioid use disorder recovery as an indicator of the app's suitability. Study participants will use the sham app for one week and will then complete a usability and user satisfaction survey. If the app is found to be exhibit acceptable usability and satisfaction, a one month study will be completed in a larger sample (see Step 2, below). If not, modifications to the app will be made and the one-week study will be repeated in a new group of participants. Step 2: After completion of the proof-of-concept study, 20 new participants will be enrolled in a 4-week trial. Study participants will complete baseline assessments and then be asked to use the app at least three times per week, for four weeks. At the end of four weeks, participants will complete usability and user satisfaction surveys.

Study participants will use the app at least three times per week. The app will contain a user interface that includes a login page, true/false questions for the user to answer, verified public domain educational information about drug and alcohol use, Likert-type questions regarding the information presented, and a closing "Thank You" screen.

The KIOS informational app will contain a user interface that includes a login page, true/false questions for the user to answer, verified public domain educational information about drug and alcohol use, Likert-type questions regarding the information presented, and a closing "Thank You" screen.

The Systems Usability Scale-Modified is a non-health outcome, single-factor, 10-item self-report scale commonly used to evaluate participants' subjective experience using software. Systems Usability Scale yields a single number representing a composite measure of the overall usability of the system being studied. Systems Usability Scale scores have a range of 0 to 100, with higher scores representing a better outcome. Systems in early development may expect to have a rating of 30, while more mature systems should rate between 60 - 80.

The Systems Usability Scale will be administered at the end of one-week for participants enrolled in Step 1 of the study and at the end of four-weeks for participants enrolled in Step 2.

A user satisfaction survey will be administered to evaluate the study participants' overall satisfaction with the app. This is a non-health outcome designed to better understand the user's perception of the app. The survey will consist of 20 statements that users will rate on a 1-7 Likert type scale (1=Disagree, 7= Agree). Satisfaction scores will be averaged and converted to percentages with higher percentages representing better user satisfaction with the app.

A user satisfaction survey will be administered at the end of one-week for participants enrolled in Step 1 of the study and at the end of four-weeks for participants enrolled in Step 2.
