Major Depressive Disorder (MDD) is characterized by negative recall biases, which may impact how individuals with depressive symptoms report physical activity (PA), sedentary, and sleep behaviors. Additionally, there are discrepancies between subjective and objective behaviors in MDD. Thus, the current study investigated whether individuals with depressive symptoms differ in their subjective and objective PA, sedentary, and sleep behaviors, and whether the magnitude of these discrepancies differ from those in individuals without depressive symptoms.
Participants from the 2011-2014 National Health and Nutrition Examination Survey (N = 8367; N = 762) with one-week of passively-collected, wrist worn actigraphy data and self-reported questionnaires assessing PA, sedentary, and sleep behaviors were analyzed.
Three negative binomial models investigated the effects of group, measurement type, and their interaction on PA, sedentary, and sleep behaviors. Individuals with depressive symptoms exhibited lower PA and sleep than individuals without depressive symptoms but did not differ in sedentary behaviors. Measurement type differed across all models: self-reported PA and sleep were lower, and self-reported sedentary behaviors were greater, than objective measurements. The interaction was significant only for PA; whereas objective PA was greater than subjective measurements for all individuals, the difference was far greater for individuals with depressive symptoms.
The absence of a clinically depressed sample and current manner of assessing subjective and objective measures may limit our generalizability and conclusions.
Our study highlights discrepancies in objective and subjective reports across domains and emphasizes the importance of incorporating objective measurements to improve psychopathology assessment.
重度抑郁症（MDD）的特征是存在负面回忆偏差，这可能会影响有抑郁症状的个体报告身体活动（PA）、久坐行为和睡眠行为的方式。此外，MDD患者的主观行为和客观行为之间存在差异。因此，本研究调查了有抑郁症状的个体在主观和客观的PA、久坐行为及睡眠行为方面是否存在差异，以及这些差异的程度与无抑郁症状的个体相比是否不同。
对2011 - 2014年国家健康与营养检查调查中的参与者（N = 8367；N = 762）进行分析，这些参与者有一周通过佩戴在手腕上的设备被动收集的活动记录仪数据，以及评估PA、久坐行为和睡眠行为的自我报告问卷。
三个负二项式模型研究了分组、测量类型及其交互作用对PA、久坐行为和睡眠行为的影响。有抑郁症状的个体比无抑郁症状的个体表现出更低的PA和睡眠时间，但在久坐行为方面没有差异。所有模型中的测量类型均有所不同：自我报告的PA和睡眠时间较低，而自我报告的久坐行为比客观测量结果更多。交互作用仅对PA有显著影响；虽然所有个体的客观PA都大于主观测量值，但有抑郁症状的个体差异要大得多。
缺乏临床抑郁症样本以及当前评估主观和客观测量的方式可能会限制我们的普遍性和结论。
我们的研究突出了各领域客观和主观报告之间的差异，并强调了纳入客观测量以改善精神病理学评估的重要性。
