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

BACKGROUND AND

objectivesSocial network site addiction is strongly correlated with sleep quality among adolescents. However, the underlying mechanisms driving these relationships require further exploration. This study aims to supplement the understanding of the psychological mechanisms linking social network site addiction and sleep quality by investigating depression as a mediating factor and difficulty describing feelings as a moderating factor.

methodsA self-report survey was conducted with 1,670 adolescents in China, assessing social network site addiction, sleep quality, depression, and difficulty describing feelings. Descriptive and correlational analyses were performed on these variables, followed by the construction of a moderated mediation model.

resultsSocial network site addiction was significantly positively correlated with sleep quality, depression, and difficulty describing feelings among adolescents. Difficulty describing feelings was also significantly positively correlated with depression. Depression partially mediated the relationship between social network site addiction and sleep quality, while difficulty describing feelings intensified the relationship between social network site addiction and depression.

conclusionThis study further elucidates the psychological mechanisms linking social network site addiction and sleep quality in adolescents. Depression acts as a mediating factor, while difficulty describing feelings strengthens the relationship between social network site addiction and depression. These findings highlight the role of difficulty describing feelings in the interplay between social network site addiction and sleep quality, offering valuable insights for a more comprehensive understanding and targeted interventions aimed at improving sleep quality in adolescents.
