Evaluating the Role of Family Context Within a Randomized Adolescent HIV-Risk Prevention Trial

The Role of Family Factors in the Outcomes of Court-Involved Youth

Court-involved youth (CIY) comprise a significant portion of the U.S. population and have a high prevalence of psychiatric illness and substance use. Youth delinquency has also been associated with family variables and parenting practices. However, it is not known which family factors are most relevant to behavioral outcomes in CIY mandated to outpatient mental health treatment. Self-report measures from 163 CIY (M = 15.19 years; 58.3% male) starting psychiatric care in two U.S. cities were utilized in a cross-sectional analysis to examine the association of parental monitoring and family functioning with the severity and variety of delinquent acts. Results demonstrate that parental monitoring is significantly associated with the delinquent behavior of CIY in mental health treatment, beyond that of psychiatric symptoms and substance use. Improved understanding of influential family factors can enhance tailoring of existing interventions to ensure that they are relevant to the needs of CIY, especially those in psychiatric treatment.

Causally Interpretable Meta-analysis: Application in Adolescent HIV Prevention

Endowing meta-analytic results with a causal interpretation is challenging when there are differences in the distribution of effect modifiers among the populations underlying the included trials and the target population where the results of the meta-analysis will be applied. Recent work on transportability methods has described identifiability conditions under which the collection of randomized trials in a meta-analysis can be used to draw causal inferences about the target population. When the conditions hold, the methods enable estimation of causal quantities such as the average treatment effect and conditional average treatment effect in target populations that differ from the populations underlying the trial samples. The methods also facilitate comparison of treatments not directly compared in a head-to-head trial and assessment of comparative effectiveness within subgroups of the target population. We briefly describe these methods and present a worked example using individual participant data from three HIV prevention trials among adolescents in mental health care. We describe practical challenges in defining the target population, obtaining individual participant data from included trials and a sample of the target population, and addressing systematic missing data across datasets. When fully realized, methods for causally interpretable meta-analysis can provide decision-makers valid estimates of how treatments will work in target populations of substantive interest as well as in subgroups of these populations.

Intervening for HIV prevention and mental health: a review of global literature

INTRODUCTION

Numerous effective HIV prevention options exist, including behaviour change interventions, condom promotion and biomedical interventions, like voluntary medical male circumcision and pre-exposure prophylaxis. However, populations at risk of HIV also face overlapping vulnerabilities to common mental disorders and severe mental illness. Mental health status can affect engagement in HIV risk behaviours and HIV prevention programmes. We conducted a narrative review of the literature on HIV prevention among key populations and other groups vulnerable to HIV infection to understand the relationship between mental health conditions and HIV prevention outcomes and summarize existing evidence on integrated approaches to HIV prevention and mental healthcare.

METHODS

We searched five databases for studies published from January 2015 to August 2020, focused on HIV prevention and mental health conditions among key populations and individuals with serious mental illness. Studies were included if they evaluated an HIV prevention intervention or assessed correlates of HIV risk reduction and included assessment of mental health conditions or a mental health intervention.

RESULTS AND DISCUSSION

We identified 50 studies meeting our inclusion criteria, of which 26 were randomized controlled trials or other experimental designs of an HIV prevention intervention with or without a mental health component. Behaviour change interventions were the most common HIV prevention approach. A majority of studies recruited men who have sex with men and adolescents. Two studies provided distinct approaches to integrated HIV prevention and mental health service delivery. Overall, a majority of included studies showed that symptoms of mental disorder or distress are associated with HIV prevention outcomes (e.g. increased risky sexual behaviour, poor engagement in HIV prevention behaviours). In addition, several studies conducted among groups at high risk of poor mental health found that integrating a mental health component into a behaviour change intervention or linking mental health services to combination prevention activities significantly reduced risk behaviour and mental distress and improved access to mental healthcare.

CONCLUSIONS

Evidence suggests that mental health conditions are associated with poorer HIV prevention outcomes, and tailored integrated approaches are urgently needed to address overlapping vulnerabilities among key populations and other individuals at risk.
