Mobile Behavioral Ecological Momentary Assessment and Intervention in Rakai, Uganda

July 20, 2020 updated by: Johns Hopkins University

Mobile Behavioral Ecological Momentary Assessment and Intervention in Rakai, Uganda: A Pilot Study

Ecological Momentary Assessment and Intervention (EMAI) is an emerging technique for gathering richer and more relevant data through repeated, longitudinal sampling of participants in their natural setting in order to deliver real-time interventions. The main study objective is to conduct a pilot EMAI study in Rakai, Uganda. Secondary objectives are to assess processes, facilitators, and barriers to EMAI. The study will compare behaviors between participants randomized to receive intervention messages and those not receiving messages. To assess EMAI validity and relevance, EMAI-collected behavioral data will be compared with traditional questionnaire-collected data.

After recruitment, participants will be given a smartphone with an application that will collect geospatial coordinates and ask behavioral assessment questions on topics including diet/alcohol, smoking, and sexual behaviors. Participants will have training on the phone and application, demonstrating proficiency with the EMAI interface prior to study start.

Days 1-30, Baseline Behaviors: Participants will complete assessment questions to establish baseline behaviors. This will include twice-daily and weekly behavioral report prompts and participant-initiated event-contingent behavioral reports. After the initial 30 day period, participants will return to the study office to complete a short questionnaire and to be randomized to the second phase of follow-up.

Days 31-90, Randomized Evaluation: Participants will be randomized in a 1:1 ratio to either continue assessment questions only (control arm) or to also begin receiving intervention messages (intervention arm) in response to reported behaviors. Messages will encourage positive behaviors and suggest alternatives to negative behaviors (e.g. "Eating a mixed diet (meats and vegetables) is a healthy way to go."). At 90 days of follow-up, participants will return to the study office to complete a brief questionnaire on behaviors and smartphone experiences.

Study hypotheses are as follows: EMAI can be successfully implemented in Uganda, and participants receiving intervention messaging will have improved self-reported health behaviors compared to controls; EMAI will be feasible and acceptable by this population; and, EMAI-collected data will correlate with traditional questionnaire-collected data.

Outcomes will be assessed using descriptive statistics, multivariate regression and analysis of themes in patient EMAI experience and acceptability.

Description

Inclusion Criteria:

  • 18 years or older
  • literate
  • current Rakai Community Cohort Study participant

We will purposely recruit a sample that has a broad range of participant characteristics in our study to optimize diversity of responses and increase study generalizability. Specific variables for which we will target sampling include: gender (~50% female), age (at least 20% among age groups 18-25, 26-35, >50), and occupation (at least 20% traders and farmers).

Exclusion Criteria:

  • Participants without a listed phone number in the Rakai Community Cohort Study

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention
On smartphones, participants in this arm will receive twice daily and weekly prompts to report on behaviors under study and be able to send self-initiated event-contingent reports on behaviors under study. In response to the behaviors they report, they receive messages on their smartphones supporting ongoing healthy behaviors or suggesting alternative behaviors to limit risks. They will complete in-person assessments at enrollment, 30-days and study exit at 90-days.
In response to behavioral data submitted intervention arm participants receive messages on their phones reinforcing healthy behaviors or encouraging alternative behaviors to limit risks
Participants will receive twice daily and weekly prompts to submit behavioral report data and self-initiate event-contingent behavioral report data submissions
Active Comparator: Control
On smartphones, participants in this arm will receive twice daily and weekly prompts to report on behaviors under study and be able to send self-initiated event-contingent reports on behaviors under study. They will complete in-person assessments at enrollment, 30-days and study exit at 90-days.
Participants will receive twice daily and weekly prompts to submit behavioral report data and self-initiate event-contingent behavioral report data submissions

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in health behavior according to EMAI self-report
Time Frame: Daily, comparing baseline (days 1-30) to follow up (days 31-90), up to a total 90 days
change in the proportion of days when participant reports 'yes' to behavior over total days behavior measured, comparing baseline to follow-up in self-reported: alcohol consumption, fruit and vegetable consumption; cigarette smoking, and sex with a non-longterm or non-marital partner
Daily, comparing baseline (days 1-30) to follow up (days 31-90), up to a total 90 days
