Summary: | The prevalence of inadequate sleep among adolescents is a significant worry due to its potential to adversely affect their health and academic performance. Addressing this matter necessitates a comprehensive grasp of the underlying factors influencing sleep regulation and the formulation of evidence-based interventions to counteract its detrimental consequences. Hence, the central objective of this study is to create and assess a dependable questionnaire designed to evaluate adolescents' self-regulation of sleep behavior.
In this cross-sectional study, data from 401 high school students randomly selected from west Iran were incorporated and subjected to psychometric assessments. The average age of the participants was 16.5 ± 0.92. Initially, 136 preliminary items were formulated, drawing from a contextual framework and comprehensive literature review. The subsequent steps involved specialized analyses, including content validity analysis, item analysis, exploratory and confirmatory factor analysis, as well as convergent validity analysis.
Both exploratory and confirmatory factor analyses support a strong structural model, including factors like self-control, outcome expectation, goal setting, and self-efficacy, which are linked to regulating sleep behavior. The model fit was satisfactory. The instrument had 22 items which demonstrated good internal consistency, adequate test-retest reliability, and evidence of convergent validity.
In future studies exploring sleep behavior, the present questionnaire, which has demonstrated initial validity and reliability, holds the potential to provide valuable assistance in evaluating and enhancing self-regulation in sleep behavior, particularly within school environments. |
