Although the Patient Health Engagement Scale (PHE-s\u00ae) 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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional psychometric validation study was conducted with 200 adolescents aged 12\u201319\u202fyears hospitalized for chronic conditions in a tertiary pediatric hospital in T\u00fcrkiye. The PHE-s\u00ae was evaluated using a multi-method approach integrating Rasch Partial Credit Modeling, categorical principal component analysis, and confirmatory factor analysis.
