BACKGROUND: HIV/AIDS remains a significant global challenge, and with the rapid advancement of technology, there has been an increasing number of interventions aimed at improving HIV/AIDS cognition and self-management behaviors among patients. However, there is still a lack of detailed literature integrating relevant evidence. OBJECTIVE: This study aims to comprehensively review existing research on interventions using modern information methods to improve HIV/AIDS cognition and enhance self-management behaviors among patients. It systematically reports the theoretical frameworks and specific intervention strategies used in current research, providing a comprehensive overview of the development status of relevant studies. We aim to compile existing evidence through this scoping review to identify potential avenues for future research. METHODS: We followed the scoping review framework proposed by the Joanna Briggs Institute for the synthesis and reporting of evidence. Relevant literature was searched using electronic databases, including PubMed, Web of Science, Embase, CINAHL, and Cochrane Library. The time frame for inclusion was from 2018 to December 1, 2023. Inclusion criteria were (1) interventions using modern information technology or new digital media, (2) studies focusing on improving HIV awareness or self-management behaviors among people living with HIV, (3) intervention studies or evaluations of intervention effects, and (4) studies published within the last five years. Two reviewers (HH and MX) independently assessed each study at both the title and abstract screening stage and the full-text review stage, resolving any disagreements through discussion. RESULTS: A total of 55 studies that met the inclusion criteria were included. The Information-Motivation-Behavioral Skills model, Social Cognitive Theory, Health Belief Model, Theory of Planned Behavior, and Information Systems Research Framework are among the most commonly used theoretical frameworks. Modern information technology interventions are mainly constructed using smartphone apps, SMS text messaging, internet-based platforms, audiovisual materials, and digital health education platforms, with smartphone apps and SMS text messaging being the most widely used intervention media. CONCLUSIONS: Modern information technology is becoming an important tool for health interventions among people living with HIV/AIDS. However, future research should focus on integrating theoretical framework guidance with intervention design, further exploring the diversity of intervention implementations, the applicability of different technological methods, their long-term effects, and how to more effectively combine traditional intervention strategies to maximize intervention outcomes.
