Psychometric validation of the Positive Drinking Consequences Questionnaire in adolescents.

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 Positive Drinking Consequences Questionnaire (PDCQ) was developed to measure positive consequences of alcohol use endorsed by college drinkers. Efforts to assess positive drinking consequences experienced by adolescents have been much more limited. The aim of the present study was to advance the psychometric testing and evaluation of the factor structure of the PDCQ in adolescents.
methodsThe current sample consisted of 173 adolescents at T1 (mean age = 15 years, range = 13-17; 61% female) who reported alcohol use in the past 12 months. Data were collected at two time points over a 12-month interval in the United States. Confirmatory factor analyses, internal consistency, test-retest reliability, and discriminant, concurrent, predictive, and incremental validity were tested.
resultsOur analyses supported four factors of positive alcohol-related consequences: sociability, liquid courage, sexual enhancement, and tension reduction. Internal consistency was moderate to high (α = 0.78-0.94, ω = 0.86-0.91 at T1; α = 0.59-0.93, ω = 0.85-0.93 at T2). Test-retest reliability was fair to good (ICC = 0.46-0.55). The PDCQ total and subscale factor scores demonstrated discriminant validity from negative alcohol expectancy. PDCQ total and subscale factor scores were positively associated with current alcohol consumption (ρs = 0.19-0.50 at T1; ρs = 0.17-0.46 at T2), indicating concurrent validity. Predictive validity analyses showed that the overall PDCQ scale score and the sociability subscale positively predicted maximum drinks 1 year later (ρs = 0.18-0.22). However, the sexual enhancement subscale was negatively predictive of typical drinking frequency 1 year later. Finally, the PDCQ showed incremental validity for concurrent alcohol consumption beyond that for alcohol expectancies and drinking motives.
conclusionThe present findings support for the reliability and validity of PDCQ for use in adolescents where it may have utility as an assessment tool for characterizing various aspects of positive drinking.
