Development and Preliminary Psychometric Properties of the Adolescent Sleep Health Belief Scale.
Article in Florence Nightingale journal of nursing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimThis study aimed to develop a scale based on the Health Belief Model that can reliably and validly evaluate adolescents' beliefs toward sleep.
methodsThis study was conducted using a methodological design with 494 adolescents between September and October 2022 in Antalya, Türkiye . Eighty-one items about sleep were created according to the Health Belief Model. Validity was assessed in terms of content and construct validity, and reliability was assessed through internal consistency. Content validity was evaluated by ten expert opinions. The scale was tested for construct validity with exploratory factor analysis, after which the scale's reliability was evaluated by examining item-total correlations using Pearson's correlation analysis and assessing internal consistency with Cronbach's Alpha.
resultsItem-level content validity index scores ranged between 0.80 and 1. The scale-level content validity index value was found to be 0.94. In the exploratory factor analysis of the 46-item scale, six factors were found with an eigenvalue greater than 1, explaining 57.7% of the total variance. The scale's item total correlations ranged from 0.26 to 0.79. Cronbach's alpha coefficients for the subscales were 0.92 for perceived susceptibility, 0.90 for perceived severity, 0.90 for perceived benefits, 0.81 for self-efficacy, 0.79 for motivation, and 0.69 for perceived barriers.
conclusionThe Adolescent Sleep Health Belief Scale demonstrated good validity and reliability in adolescents. Its cross-cultural adaptation for use with adolescents in other countries is recommended.
