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

objectivesThe main purpose of the present study was twofold: to validate the Prodromal Questionnaire-Brief (PQ-B) in a community-derived sample of adolescents and to examine the links between psychotic-like experiences and emotional and behavioral problems, prosocial behavior, suicidal ideation, and bipolar-like experiences.

methodOne thousand five hundred eighty-eight students selected by random sampling participated in a cross-sectional survey. The PQ-B, Paykel Suicide Scale, Strengths and Difficulties Questionnaire, Mood Disorder Questionnaire, Penn Matrix Reasoning Test, Family Affluence Scale-II, and Oviedo Infrequency Scale were used.

resultsThe unidimensional factorial structure of the PQ-B items showed adequate goodness of fit index. This model also showed configural and strong invariance across gender. The internal consistency of the PQ-B total frequency score was 0.92. A high degree of overlap was found between psychotic-like experiences and emotional and behavioral problems, suicidal ideation, and bipolar-like experiences.

conclusionThe PQ-B is a brief, easy, and reliable tool for screening psychotic-like experiences in adolescents from the general population. The assessment of risk for psychosis and its relationship with other psychopathological risk factors in a close-in strategy or two-stage process model may help us to enhance the early identification for youths at heightened risk for serious mental disorders.
