1 · What the graph read from it

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.

2 · The registry

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

objectiveReinforcement Sensitivity Theory (RST) provides a theoretical foundation associated with various approach and avoidance behaviors and individual personality differences. Sensitivity to reward and punishment, two neural systems within the RST have been significantly associated with bingeing and purging behaviors. However, inconsistent findings are observed and specific factors mediating these relationships are not well understood. Deficits in emotion regulation may account for these relationships, as both negative urgency and distress tolerance have been independently associated with bulimia behaviors. Thus, this is an area that requires further investigation.

methodThe current study utilized various self-report inventories, including the Eating Disorder Inventory-3rd Edition to measure bulimia symptoms, as well as measures of negative affect, sensitivity to reward and punishment, distress tolerance, and negative urgency. These measures were used to assess whether distress tolerance and negative urgency mediated associations between sensitivity to reward and punishment and bulimia symptoms in a community sample of 394 young adults ranging from the ages of 18 to 25.

resultsAs expected, sensitivity to reward and punishment were significantly associated with decreased distress tolerance. Distress tolerance was also directly associated with greater negative urgency, which was significantly associated with increased bulimia symptoms. Consistent with hypotheses, indirect associations between sensitivity to reward and sensitivity to punishment to bulimia symptoms via distress tolerance and negative urgency were observed, controlling for gender and negative affect. DISCUSSION: Results contribute to understanding specific contributions of risk factors within the relationship of sensitivity to reward and punishment and bulimia symptoms, measured by the EDI-3. Novel to existing literature, results indicate that reinforcement sensitivity significantly contributes to emotion regulation deficits. Thus, these findings may have important implications for understanding the development and treatment of bulimia symptoms. LEVEL OF EVIDENCE: Level V, based on descriptive, cross-sectional data.
