Development of a questionnaire for problematic social networking sites use: Ensuring content validity through Delphi methodology.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis study aimed to develop a questionnaire to assess problematic social network service use (PSNSU) applicable to both adolescents and adults to ensure content validity.
methodsA Delphi survey methodology with a panel of 16 experts was employed from April to June 2024 to ensure the content validity of the PSNSU assessment tool. This study involved three rounds of Delphi surveys to collect both open- and closed-ended responses to the PSNSU questionnaire. Data analysis focused on calculating the content validity ratio (CVR), stability, and consensus of each item. Items that did not meet the threshold criteria were revised or removed based on expert feedback.
resultsThe PSNSU questionnaire initially included three domains and 59 items. Following Round 1 of the Delphi survey, three domains, 11 subdomains, and 43 items were selected. After adding and modifying the domains and items, Round 2 resulted in a questionnaire with two domains, 10 subdomains, and 42 items. In Round 3, the revised PSNSU questionnaire showed an average CVR of 0.99, a stability of 0.10, and consensus of 0.97, thus concluding the Delphi process.
conclusionsThe final PSNSU questionnaire encompasses a wide range of issues related to addictive behaviors and occupational challenges. Content validity was validated through the Delphi survey, resulting in a comprehensive tool that reflects the multidimensional characteristics of PSNSU across different life stages. This tool can be used for both clinical assessments and research to better understand and address PSNSU.
