Internet-Based Motivational Interviewing Intervention for Colonoscopy in African Americans

PRIMARY OBJECTIVES:

I. To develop and field-test an app, called e-Motivate, designed to improve African Americans’ screening colonoscopy rates.

II. To conduct a randomized controlled trial (RCT) that examines the efficacy of the Motivate app versus a control condition for increasing screening colonoscopy uptake in African Americans.

IIa. To explore the efficacy of the e-Motivate app for improving a secondary adherence outcome.

IIb. To explore mediators and moderators of the e-Motivate app.

III. To examine participants' satisfaction with the e-Motivate app.

OUTLINE:

Phase I: Field testing

Using an iterative approach, the e-Motivate app will be developed, field-tested, and finalized. Drawing from the current literature and our pilot data, we will design the e-Motivate app version 1.0. Then, the app will be field-tested on African Americans referred for a screening colonoscopy (N=20). Qualitative methods (e.g., think aloud exercises) will be implemented to assess the intervention’s feasibility. Quantitative methods will be used to assess the app’s overall usability and acceptability. The results from the first field test will be used to modify the app. Study procedures will be repeated with a new sample (N=20) of African Americans referred for a screening colonoscopy to confirm the feasibility of the I-MIIC 2.0. Based on the results of the second field test, the finalized I-MIIC 3.0 will be created.

PHASE II (RCT): Participants will be African Americans referred for a screening colonoscopy. Participants will be randomly assigned to one of two groups: (1) e-Motivate condition or (2) control condition. Participant in the control condition will receive usual care (i.e., patient navigation). Participants in the e-Motivate condition, in addition to receiving usual care, will complete the app on a tablet in the clinic.
