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

There is a general belief that mental health problems are increasing in younger generations, though little objective comparisons exist. The current meta-analysis examines changes in subclinical mean-level overall symptom burden and shifts in specific domains among population-based samples of youth (1-18 years) globally over the last four decades. We search systematically in PubMed, Web of Science, Scopus, EBSCO and Google Scholar with pre-registered criteria. Included studies (k = 175, N = 418,528) use the standardized and cross-culturally validated Child Behavior Checklist with parent-, teacher-, and self-report. A cross-temporal meta-analysis is conducted with data points between 1981 to 2019. Age, sex, response rate, and geographic continent, used as moderators. Meta-regression analyses, with year of data collection as a predictor, shows overall symptom burden did not change in the past 40 years except for some decreases in early childhood (parent report), middle childhood (self-report) and teenage boys (self-report). There is evidence of change in specific symptom domains. We find strong, multi-informant evidence for decreased externalizing problems (parent report and self-report in girls) including aggression in middle childhood over time (parent report and self-report), and internalizing problems (parent and teacher report of boys and girls) in middle childhood. Single-informant changes show varying patterns in subscales of internalizing problems with increases in anxiety/depression in teens (parent report) and somatic complaints in teenage boys (self-report) next to a decrease in withdrawn/depressed symptoms (self-report of children and youth overall and parent report in middle childhood). Further single-informant changes suggest an increase in social problems in European teens (self-report) and a decrease in rule-breaking behavior (parent report). Finally, contradicting results were found for attention problems (an increase based on parent report and a decrease in middle childhood boys based on teacher report) and thought problems (an increase based on parent report and decrease in teenage boys based on self-report). However, the finding regarding attention problems should be interpreted cautiously given declining reliability of the subscale over time and evidence suggesting potential measurement non-invariance. In sum, our results do not support concerns that young people today have more overall symptom burden than previous generations, rather, they show a different composition of symptom profiles. However, an important limitation of the study is that post COVID-19 changes were not studied.
