ABSTRACT Understanding the relationship between subjective and objective sleep measures is essential for evaluating their agreement utility. This study compared Munich Chronotype Questionnaire (MCTQ) Fitbit metrics duration, midpoint social jetlag in 5252 participants from Adolescent Brain Cognitive Development (ABCD) study. Linear nonlinear models assessed relationships Fitbit‐derived MCTQ‐reported metrics, whilst moderation analyses examined influence of age, sex, household income BMI. A sensitivity analysis results pre‐ post‐COVID‐19 to assess pandemic‐related effects (pre‐COVID n = 4451). Correlations were weak moderate: r 0.15–0.21 0.37–0.42 midpoint, 0.12–0.16 jetlag. Quadratic LOESS confirmed trends with greater Fitbit‐MCTQ divergence at extreme morningness or eveningness. classified 63.2% as having insufficient sleep, 39.45% MCTQ, suggesting underestimates duration. Bland–Altman plots MCTQ overestimation, especially shorter sleepers. BMI was significantly associated duration jetlag, higher linked variability. Household moderated specific age sex did not moderate any metric. Sensitivity showed consistent across post‐COVID periods. Findings highlight stronger than methodological differences driving discrepancies. The consistency demographics time periods supports complementary use adolescent assessment.
