Participants self-reported the time they left and arrived at home and school through a commuting diary. They wore a GPS device recording the objective time during three trips (i.e., one home-school trip and two school-home trips). Agreement between commuting diary and GPS data regarding home-school trips and school-home trips was evaluated using Bland-Altman plots.<h4>Results</h4>Total commuting time differedInternational journal of environmental research and public healthConvergent Validation of a Self-Reported Commuting to and from School Diary in Spanish Adolescents.PMC9819640DEP2016-75598-R, MINECO/FEDER, UEFPU17/03934, FPU18/04251Aranda-Balboa MJChillon PCampos-Garzon PGalvez-Fernandez PHenriksson PLara-Sanchez AJMolina-Soberanes DSegura-Jimenez VSaucedo-Araujo RGHerrador-Colmenero MfalseConvergent Validation of a Self-Reported Commuting to and from School Diary in Spanish Adolescents.The aim of this study was to examine the convergent validity of self-reported diary times for commuting to and from school with device-measured positional data (Global Positioning System; GPS) in Spanish adolescents.<h4>Methods</h4>Cross-sectional data were obtained from four Spanish public secondary schools in 2021, comprising 47 adolescents and 141 home-school and school-home trips.
