Psychometric evaluation of the Patient Health Engagement Scale (PHE-s®) in adolescents with chronic diseases: evidence from Türkiye.
Article in Frontiers in psychology, 2026. 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
Aim: Patient engagement is increasingly recognized as a key determinant of adolescents' adaptation to chronic illness; however, developmentally sensitive measures capturing engagement trajectories in youth remain scarce. Although the Patient Health Engagement Scale (PHE-s®) has demonstrated robust psychometric properties in Turkish adult populations, its applicability to adolescents has not yet been examined. The objective of this study was to examine its psychometric properties among adolescents with chronic diseases in a Turkish inpatient sample. Methods: A cross-sectional psychometric validation study was conducted with 200 adolescents aged 12-19 years hospitalized for chronic conditions in a tertiary pediatric hospital in Türkiye. The PHE-s® was evaluated using a multi-method approach integrating Rasch Partial Credit Modeling, categorical principal component analysis, and confirmatory factor analysis. Internal consistency, test-retest reliability, and differential item functioning across demographic and clinical subgroups were examined. Concurrent validity was assessed through associations with the Child Attitude Toward Illness Scale (CATIS). Results: Analyses supported a unidimensional structure of the adolescent PHE-s®, with strong item loadings and acceptable model fit across analytic approaches. The scale demonstrated high internal consistency (ordinal Conclusion: The Turkish PHE-s® is a reliable and valid instrument for assessing psychological engagement trajectories among adolescents with chronic diseases in inpatient settings.
