Brief Summary

Inadequate adherence to antiretroviral therapy (ART) can impede successful viral suppression and consequently lead to negative health consequences. This study aims to refine and test the efficacy of a mobile health ART adherence application (ARTAA), delivered over a smartphone, with helping individuals improve their ART adherence.

Detailed Description

The CDC estimates that 1.1 million people living in the U.S. are infected with HIV \[1\]. Only a quarter of person living with HIV (PLWH) successfully keep the virus under control \[2\]. Medication non-adherence is a significant contributor to unsuccessful viral suppression; a recent meta-analysis found that only an estimated 59% of participants in North American studies were adherent at a commonly accepted minimal threshold for successful viral suppression \[3\]. While newer antiretroviral therapy (ART) medications can produce viral suppression at lower levels of adherence, relatively high adherence is still necessary to avoid disease progression and shortened lifespan \[4-6\]. In addition, low levels of adherence increase the risk of infecting others and contribute to the development of treatment resistant strains of HIV \[7;8\].

Interventions have been developed to address the significant public health problem presented by poor adherence, with most studies demonstrating some degree of success in the short-term \[9\]. However, the impact of the interventions is generally not sustained over time \[9\], and most HIV treatment settings do not have the resources to deliver more intensive interventions. As a result, there has been interest in developing efficacious electronically-delivered interventions. Very little research has focused on establishing the efficacy of mobile health applications for ART adherence. Further, no published studies have examined a single session face-to-face intervention combined with a mobile application and coaching support to reinforce sustained adherence.

Delivered over a smartphone, portable applications would allow for real-time adherence tracking and feedback and ready access to content or services to enhance adherence. The long-term goal of this line of research is to disseminate an efficacious, mobile health ART adherence application that can be integrated readily into clinical care. The objective of this application is to develop a mobile health ART adherence application, to pilot the application, and to conduct a preliminary randomized controlled trial of the application.

Arm && Interventions

Group	Intervention	Description
Mobile Health ART Adherence Application (mARTAA)	Twine Collaborative Care Application	mARTAA will use a smartphone-delivered application developed by Twine Health, Inc.
Face-to-Face ART Adherence Intervention	Information-Motivation-Behavioral Skills Model of ART Adherence	A single face-to-face ART adherence intervention will be administered.

Primary Outcome Measures

Name	Time	Method
ART Adherence	12 Months	Percentage of ART adherence based on Electronic Pill Box data will be compared between the groups

Secondary Outcome Measures

Name	Time	Method
Information, Motivation, and Behavioral Skills	12 Months	Group differences will be examined in motivation as assessed by the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire.
Viral Load	12 Months	Viral load will be dichotomized into three levels (20, 48, and 400 copies/ML) and intervention effects will be examined at each of these levels.
Self-Reported ART Adherence	12 Months	Self-reported ART adherence as measured by the AACTG Medication Adherence Questionnaire will be compared between the groups.
Information	12 Months	Group differences will be examined in information as assessed by the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire.
Self-Efficacy	12 Months	Group differences will be examined in self-efficacy as assessed by the HIV Treatment Adherence Self-Efficacy Questionnaire
Behavioral Skills	12 Months	Group differences will be examined in behavioral skills as assessed by the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire.
