Single-session interventions (SSIs) have emerged as a promising approach for addressing both HIV risk behaviors and mental health issues among adolescents and young adults (AYA). Despite significant progress in HIV prevention and treatment, mental health remains a critical factor in improving engagement and outcomes. The relationship between mental health and HIV is complex and bidirectional—mental health challenges can increase the risk of HIV transmission, while living with HIV can exacerbate mental health conditions. This interconnectedness highlights the need for holistic, integrated interventions that simultaneously address both domains.
SSIs are defined as structured programs that involve only one session, making them cost-effective and scalable. They have been shown to improve knowledge of HIV prevention, reduce stigmatizing attitudes, and enhance self-assessment of HIV risk. These interventions often incorporate evidence-based psychological techniques, such as motivational interviewing and behavioral activation, which are also effective in addressing mental health concerns. By combining these elements, SSIs have the potential to improve both HIV-related outcomes and mental health indicators.
Research indicates that SSIs grounded in social cognitive theory and behavioral activation can lead to synergistic effects. For example, interventions that promote safer sexual practices through goal-setting and self-reflection may also reduce symptoms of depression. This dual impact is particularly relevant for AYA, who often face overlapping mental health and HIV risk challenges. However, most existing SSIs have focused primarily on either HIV prevention or mental health outcomes, with limited integration of both. This review of 21 SSIs targeting AYA found that 19 focused on HIV prevention, while only two included mental health outcomes, despite the interventions being based on theories and techniques commonly used in mental health interventions.
The integration of mental health services into HIV care offers significant benefits, including better clinical outcomes, reduced substance use, and improved social functioning. However, barriers such as provider shortages and fragmented service delivery systems hinder the widespread implementation of these integrated approaches. SSIs offer a viable solution by providing effective, one-time interventions that can be easily integrated into existing care systems. This makes them particularly suitable for resource-limited settings where multi-session programs may be impractical.
Despite their potential, there is still a need for more research on SSIs that explicitly combine HIV risk behavior reduction and mental health support. Current evidence suggests that these interventions can be as effective as multi-session programs in certain contexts, particularly in improving prevention-related outcomes. However, to maximize their impact, future research should incorporate mental health-related outcomes into these interventions. This would not only enhance their effectiveness but also contribute to a more comprehensive understanding of how mental health and HIV risk behaviors can be addressed together.
The findings from this review have important implications for clinical practice and public health. SSIs offer a cost-effective and impactful strategy to extend the reach of HIV treatment and prevention efforts. By integrating mental health support, these interventions can help address the underlying psychological factors that contribute to HIV risk behaviors. This is especially important for AYA, who may be reluctant to engage in more intensive support programs. As the evidence continues to grow, it is essential to prioritize the development and implementation of SSIs that address both HIV risk behaviors and mental health issues. This will require collaboration between mental health professionals, HIV care providers, and public health officials to ensure that these interventions are accessible and effective for all individuals in need.
Conclusion
The integration of mental health and HIV risk behavior interventions through single-session interventions (SSIs) offers a promising approach for addressing the complex and interconnected challenges faced by adolescents and young adults. These interventions are cost-effective, scalable, and grounded in evidence-based psychological techniques. While current research primarily focuses on either HIV prevention or mental health outcomes, the shared mechanisms of change suggest that SSIs can have a dual impact on both domains. By incorporating mental health-related outcomes into these interventions, it is possible to enhance their effectiveness and ensure that they address the holistic needs of individuals at risk for HIV. Future research should continue to explore the potential of SSIs in this context, with the goal of developing more comprehensive and integrated approaches that improve both HIV-related outcomes and mental health.
