Exploring Alcohol Use Expectancies as Mediators in the Relationship Between Psychological Stressors and Substance Use Among Youths Living with HIV in Uganda.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We investigated the mediating role of alcohol use expectancies between three psychological/emotional states (depressive symptoms, hopelessness, and adverse childhood experiences (ACE)) and problematic alcohol and substance use among YLHIV in Uganda. We defined problematic substance use according to the National Institute on Drug Abuse (NIDA)-modified Alcohol, Smoking, and Substance Involvement Screening Test (NM-ASSIST) to derive a Substance Involvement (SI) score to identify participants' risk level. We grouped moderate and high risk into one category to represent 'problematic use' or use that would qualify as a substance use disorder. We tested the proposed mediation models using the PROCESS macro for mediation, moderation, and conditional process analysis version 4.1 for SPSS. We observed that higher scores for depressive symptoms, hopelessness, and ACE, were each associated with increased levels of global AUE (GAUE). However, mediation analyses revealed significant indirect effects of depressive symptoms (1.03, 95% CI 1.0002 to 1.0926), hopelessness (1.11, 95% CI 1.0172 to 1.3349), and ACE (1.08, 95% CI 1.0027 to 1.2695) on problematic substance use via GAUE. Also negative AUE (NAUE) significantly mediated the relationship between depressive symptoms, hopelessness, and ACE and problematic substance use. Our study highlights the significant role of GAUE and NAUE in mediating the relationship between ACE, depressive symptoms, hopelessness, and problematic substance use among YLHIV. The findings suggest that interventions targeting GAUE and NAUE and possibly providing effective coping mechanisms for managing depressive symptoms, hopelessness, and the impact of ACE may be crucial in reducing substance use among YLHIV.
