Youth Leisure-Time Sedentary Behavior Questionnaire (YLSBQ): Reliability and Validity in Colombian University Students. Int J Environ Res Public Health. 2021 Jul 26;18(15):7895http://hdl.handle.net/10668/18320Sedentary behavior (SB) is influenced by variations in social, cultural and economic contexts. This study assesses the test-retest reliability and validity of the Youth Leisure-time Sedentary Behavior Questionnaire (YLSBQ), a self-report tool that examines total and domain-specific SB in a cohort of young adults from Colombia. A cross-sectional validation study was conducted among 447 Colombian college students (52.8% men; mean (± standard deviation) age of 19.55 ± 2.54 years). To assess the reliability of the YLSBQ, Kappa statistics (k) were used. A confirmatory factor analysis (CFA) was conducted to determine validity. The Cronbach alpha for the 12 behaviors of the YLSBQ showed a good-to-excellent internal consistency (0.867, ranging from 0.715-0.935). Intraclass correlation coefficient (ICC) indicated that 10 items (83.0%) and two items (17.0%) showed excellent and good reliability, respectively. Furthermore, ICC between the total sedentary time was 0.926 (95% confidence interval [CI] = 0.912 - 0.939), which was interpreted as excellent. The goodness-of-fit tests provided evidence that overall, a four-factor solution was an adequate fit with the time scores. In conclusion, the YLSBQ could be considered a reliable, valid and usable tool for the assessment of SB in young adults in a Latin American country. We found that the psychometric properties of the questionnaire were similar to those of the original Spanish validation study.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Latin AmericanQuestionnaireReliabilityScreen timeSedentaryValidityYoung adultsAdolescentAdultColombiaCross-Sectional StudiesFemaleHumansLeisure ActivitiesMalePsychometricsReproducibility of ResultsSedentary BehaviorStudentsSurveys and QuestionnairesUniversitiesYoung Adultresearch article34360186open accessActividades recreativasConducta sedentariaEncuestas y cuestionariosEstudiantesPsicometríaReproducibilidad de los resultadosUniversidades10.3390/ijerph181578951660-4601PMC8345489https://www.mdpi.com/1660-4601/18/15/7895/pdf?version=1627293536https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8345489/pdf
