Development and initial validation of a marijuana cessation expectancies questionnaire.
Article in Drug and alcohol dependence, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe present research examines anticipated consequences of ceasing or reducing marijuana use with initial development and psychometric validation of a measure of marijuana cessation expectancies.
methodsThe 46-item Marijuana Cessation Expectancies Questionnaire (MCEQ) was initially developed from the content validity analysis of free responses about expected outcomes of stopping and decreasing marijuana use generated by 94 participants. The closed-ended MCEQ was subsequently administered to 151 non-treatment seeking regular marijuana users (used on M=64.7% of the prior 60days, SD=25.1%;M
resultsExploratory factor analyses identified six MCEQ factors that accounted for 61% of variance, which were related to expected improvement in: 1) performance/motivation, 2) problems with authority, and 3) interpersonal functioning, and expected worsening of 4) mood states and 5) fun experiences, and 6) changes in appetite/weight from cessation/reduction of marijuana use. Internal consistency of full scale items was good (α=0.86) and moderate to high for all factors (α's=0.60-0.89). The MCEQ items showed good concurrent validity with key measures and incremental associations with change indices (prior history of cessation/reduction attempt, benefits of reduction, importance of change), beyond the effects of marijuana use expectancies.
conclusionsThese data provide initial support for the MCEQ and suggest it is closely linked to reduction/cessation decisions in marijuana users. MCEQ may be used clinically to enhance existing behavioral treatments and motivational interventions for problem marijuana use.
