Promoting Adherence
• Standard of Care
• Research Interventions
– Amico et al., 2006
• d=0.35 – 0.19 if ART naïve, 0.62 if pre-selected for MNA

2. Data Collection
• Inclusion Criteria:
– intervention studies that examine the use of electronic, text-based messaging to promote ART adherence in HIV+ samples
– sufficient results to calculate effect size
• Databases Searched: PsycINFO, PubMed/ Medline, Academic Search Premier, CINAHL, & ProQuest Dissertations and Theses
• Reverse search: references of all relevant studies
