Leveraging Ecological Momentary Assessment Data to Characterize Individual Mobility: Exploratory Pilot Study in Rural Uganda.

Background: The geographical environments within which individuals conduct their daily activities may influence health behaviors, yet little is known about individual-level geographic mobility and specific, linked behaviors in rural low- and middle-income settings.

Objective: Nested in a 3-month ecological momentary assessment intervention pilot trial, this study aims to leverage mobile health app user GPS data to examine activity space through individual spatial mobility and locations of reported health behaviors in relation to their homes.

Methods: Pilot trial participants were recruited from the Rakai Community Cohort Study-an ongoing population-based cohort study in rural south-central Uganda.

Motivational interviewing experiences from a community health worker-led HIV prevention and care intervention in rural Uganda: a qualitative study.

Motivational Interviewing (MI) and Community Health Workers (CHWs) are increasingly utilized in global settings to improve HIV outcomes, yet research exploring implementation strategies using MI and CHWs is lacking. We examined the experiences of CHWs and their clients in a counseling intervention which used MI-informed counseling to increase engagement in HIV prevention and treatment. This study was nested within the mLAKE cluster-randomized trial in a high HIV prevalence fishing community in rural Rakai District, Uganda.

Mixed Methods, Implementation Science Evaluation of a Community Health Worker Strategy for HIV Service Engagement in Uganda.

Background: A trial found that a community health worker (CHW) strategy using "Health Scouts" improved HIV care uptake and ART coverage. To better understand outcomes and areas for improvement, we conducted an implementation science evaluation.

Methods: Using the RE-AIM framework, quantitative methods included analyses of a community-wide survey (n = 1903), CHW log books, and phone application data.

Acceptability and feasibility of mobile phone-based ecological momentary assessment and intervention in Uganda: A pilot randomized controlled trial.

Valid, reliable behavioral data and contextually meaningful interventions are necessary for improved health outcomes. Ecological Momentary Assessment and Intervention (EMAI), which collects data as behaviors occur to deliver real-time interventions, may be more accurate and reliable than retrospective methods. The rapid expansion of mobile technologies in low-and-middle-income countries allows for unprecedented remote data collection and intervention opportunities.

Impact of community health worker intervention on PrEP knowledge and use in Rakai, Uganda: A mixed methods, implementation science evaluation.

Background: Effective models of support for HIV pre-exposure prophylaxis (PrEP) are needed for populations at elevated risk. In a hyperendemic Ugandan fishing community, PrEP counseling was provided through a situated Information, Motivation, and Behavioral Skills (sIMB)-based community health worker (CHW) intervention. We evaluated the intervention using a mixed-methods, implementation science design.

HIV Prevention and Treatment Behavior Change and the Situated Information Motivation Behavioral Skills (sIMB) Model: A Qualitative Evaluation of a Community Health Worker Intervention in Rakai, Uganda.

A community health worker (CHW) model can promote HIV prevention and treatment behaviors, especially in highly mobile populations. In a fishing community in Rakai, Uganda, the Rakai Health Sciences Program implemented a CHW HIV intervention called Health Scouts. The situated Information, Motivation, and Behavioral Skills (sIMB) framework informed the design and a qualitative evaluation of the intervention.

Mobile Ecological Momentary Assessment and Intervention and Health Behavior Change Among Adults in Rakai, Uganda: Pilot Randomized Controlled Trial.

Background: An extraordinary increase in mobile phone ownership has revolutionized the opportunities to use mobile health approaches in lower- and middle-income countries (LMICs). Ecological momentary assessment and intervention (EMAI) uses mobile technology to gather data and deliver timely, personalized behavior change interventions in an individual's natural setting. To our knowledge, there have been no previous trials of EMAI in sub-Saharan Africa.

Novel community health worker strategy for HIV service engagement in a hyperendemic community in Rakai, Uganda: A pragmatic, cluster-randomized trial.

Background: Effective implementation strategies are needed to increase engagement in HIV services in hyperendemic settings. We conducted a pragmatic cluster-randomized trial in a high-risk, highly mobile fishing community (HIV prevalence: approximately 38%) in Rakai, Uganda, to assess the impact of a community health worker-delivered, theory-based (situated Information, Motivation, and Behavior Skills), motivational interviewing-informed, and mobile phone application-supported counseling strategy called "Health Scouts" to promote engagement in HIV treatment and prevention services.

Methods And Findings: The study community was divided into 40 contiguous, randomly allocated clusters (20 intervention clusters, n = 1,054 participants at baseline; 20 control clusters, n = 1,094 participants at baseline).

Design and Implementation of a Community Health Worker HIV Treatment and Prevention Intervention in an HIV Hot Spot Fishing Community in Rakai, Uganda.

Innovative approaches are needed to increase engagement in HIV treatment and prevention services, particularly in HIV hot spots. Here, we detail our design, training approach, and early implementation experiences of a community-based HIV intervention called "health scouts." The intervention, utilizing a novel, theory-based approach, trained 10 community residents in an HIV hot spot fishing community to use motivational interviewing strategies and a mobile phone-based counseling application.

Peer health workers and AIDS care in Rakai, Uganda: a mixed methods operations research evaluation of a cluster-randomized trial.

Settings with limited health care workers are challenging environments for delivery of antiretroviral therapy. One strategy to address this human resource crisis is to task shift through training selected patients as peer health workers (PHWs) to provide care to other individuals receiving antiretroviral therapy. To better understand processes of a cluster-randomized trial on the effect of these PHWs on AIDS care, we conducted a mixed methods operations research evaluation.

Telecommunications and health Care: an HIV/AIDS warmline for communication and consultation in Rakai, Uganda.

Hotlines and warmlines have been successfully used in the developed world to provide clinical advice; however, reports on their replicability in resource-limited settings are limited. A warmline was established in Rakai, Uganda, to support an antiretroviral therapy program. Over a 17-month period, a database was kept of who called, why they called, and the result of the call.
