Abstract
Sedentary 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.
Highlights
Significant differences were observed between males and females, with respect to body weight (p = 0.001) and height (p < 0.001)
This study examined the psychometric properties of the Youth Leisure-time Sedentary Behavior Questionnaire (YLSBQ) in a population of young adults from Colombia and demonstrated that the YLSBQ had good-to-excellent validity and reliability in this specific population
Our findings suggest that the YLSBQ could be considered a reliable, valid and usable tool for the assessment of Sedentary behavior (SB) in young adults within a Latin American country
Summary
Sedentary behavior (SB) is defined on the basis of energy expenditure, i.e., any behavior in which energy expenditure is strictly below 2 METs (metabolic equivalent tasks) [1], or between 1 MET and 1.8 METs [2]. Since that criterion alone is not enough to clarify what SB is [3], the Sedentary Behavior Research Network (SBRN) undertook the Terminology Consensus Project and defined SB as “any waking behavior characterized by an energy expenditure ≤ 1.5 METs while in a sitting or reclining posture” [4]. Common SBs include watching television (TV), using the computer, playing video games, using phones (collectively referred to as screen time), sitting in cars, and reading [5].
