The role of reward and reinforcement in understanding alcohol use among adults living with HIV in South Africa.
Article in Psychology of addictive behaviors : journal of the Society of Psychologists in Addictive Behaviors, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveMost research investigating reinforcement in alcohol use is from high-income countries. The current study sought to understand the association of different reinforcement types (alcohol-specific reward, environmental reward, behavioral activation) with multiple measures of alcohol use and cravings among individuals living with HIV in South Africa.
methodBaseline data were obtained from a substance use clinical trial in Cape Town (
resultsEach percentage point increase in income spent on alcohol was significantly associated with PEth, RR = 1.004 [95% CI (1.001, 1.007)], which translates to a 13.6% increase in the relative risk of unhealthy alcohol use for the average person in the study. More alcohol-specific reward was significantly associated with higher scores on the AUDIT-C, higher average number of drinks on the TLFB, and more cravings. Higher activation was associated with lower scores on the AUDIT-C. Neither subscale of environmental reward was associated with model outcomes.
conclusionGreater alcohol-specific reward and less behavioral activation were associated with more frequent and unhealthy alcohol use in this setting, but not environmental reward. Findings highlight how different reinforcement types potentially influence alcohol use in a low-resource global setting. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
