Q-single: Linking functional impairment to problematic internet use through a single-question approach.

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
Background: Short versions of problematic internet use (PIU) questionnaires may provide a convenient and effective way of assessing internet-related problems in various contexts, ranging from research to clinical practice. The aim of this study was to investigate whether single yes/no question (Q-single) regarding "functional impairment due to PIU" could serve as a screening tool to indicate the potential absence of PIU, given the lack of functional impairment. Methods: Data from two online studies (N = 524 and N = 272) assessing internet-related behaviors among students were used for the analyses. Participants completed questionnaires (the nine-item Problematic Internet Use Questionnaire [PIUQ-9], the Compulsive Internet Use Scale [CIUS], the nine-item Patient Health Questionnaire, depression module [PHQ-9], the seven-item Generalized Anxiety Disorder scale [GAD-7]), questions about their internet use time, besides answering the Q-Single question. Block-wise multiple linear regression analyses were used to determine the predictive effect of the Q-Single on PIU (as measured with the PIUQ-9 and the CIUS) and its association with depression and anxiety symptom scores (as measured with the PHQ-9 and the GAD-7). Results: The Q-Single demonstrated a high negative predictive value in screening the absence of PIU, however positive predictive value was low to moderate. Q-Single proved to be a good predictor of PIU (β = 0.484, p < 0.001 [PIUQ-9] and β = 0.481, p < 0.001 [CIUS]) when controlling for age, gender, and internet use time. Adjusting for the same controlling variables, the Q-Single had a moderate association with depression symptoms (β = 0.385, p < 0.001 [PHQ-9]) and anxiety symptoms (β = 0.252, p < 0.001) [GAD-7]) supporting the validity of the single-question instrument. Conclusions: The finding that a single question could predict absence of PIU in students, implies that functional impairment is an important indicator of PIU.
