Willpower versus "skillpower": Examining how self-efficacy works in treatment for marijuana dependence.
Trial report in Psychology of addictive behaviors : journal of the Society of Psychologists in Addictive Behaviors, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Self-efficacy has repeatedly been demonstrated to be a robust predictor of outcomes in the treatment of marijuana use disorders. It is not clear, however, how increases in confidence in ability to refrain from use get translated into actual improvements in drug-related outcomes. Marlatt, among others, viewed the acquisition and use of coping skills as the key to behavior change, and self-efficacy as a cognitive state that enabled coping. But that model of behavior change has not been supported, and few studies have shown that the effects of self-efficacy are mediated by coping or by other processes. The current study combined 3 marijuana treatment trials comprising 901 patients to examine the relationships between self-efficacy, coping, and potential mediators, to determine if the effects of self-efficacy on outcomes could be explained. Results of multilevel models indicated that self-efficacy was a strong predictor of adaptive outcomes in all trials, even when no active treatment was provided. Tests of mediation showed that effects of self-efficacy on marijuana use and on marijuana-related problems were partially mediated by use of coping skills and by reductions in emotional distress, but that direct effects of self-efficacy remained largely unexplained. The results are seen as supportive of efforts to improve coping skills and reduce distress in marijuana treatment, but also suggest that additional research is required to discover what is actually occurring when substance use changes, and how self-efficacy enables those changes.
