Abstract

BACKGROUND

Bedtime procrastination is a serious threat to youths' sleep quality and physical and mental health. It is affected by various psychological and physiological factors, but few studies focused on the impact and internal mechanism of childhood experience on bedtime procrastination in adulthood from the evolutionary and developmental perspective.

OBJECTIVE

This study aims to explore the distal factors of bedtime procrastination among young people, that is, the association between childhood environmental risk (harshness and unpredictability) and bedtime procrastination, as well as the mediating roles of life history (LH) strategy and sense of control.

PARTICIPANTS AND SETTING

By convenience sampling, 453 Chinese college students aged 16 to 24 (55.2 % males, M = 21.21 years) completed questionnaires regarding demographics, childhood environmental harshness (from neighborhood, school, and family), and unpredictability (parental divorce, household moves, and parental employment changes), LH strategy, sense of control, and bedtime procrastination.

METHODS

Structural equation modeling was used to test the hypothesis model.

RESULTS

The results showed that childhood environmental harshness and unpredictability were both positively associated with bedtime procrastination. Sense of control had a partial mediating role between harshness and bedtime procrastination (B = 0.02, 95%CI = [0.004, 0.042]), and between unpredictability and bedtime procrastination (B = 0.01, 95%CI = [0.002, 0.031]), respectively. LH strategy and sense of control had a serial mediating role between harshness and bedtime procrastination (B = 0.04, 95%CI = [0.010, 0.074]), and between unpredictability and bedtime procrastination (B = 0.01, 95%CI = [0.003, 0.029]), respectively.

CONCLUSIONS

The findings suggest that childhood environmental harshness and unpredictability are potential predictors of youths' bedtime procrastination. Young people can reduce bedtime procrastination problems by slowing LH strategies and improving their sense of control.

摘要

背景

睡眠拖延是青少年睡眠质量和身心健康的严重威胁。它受到各种心理和生理因素的影响，但从进化和发展的角度来看，很少有研究关注童年经历对成年人睡眠拖延的影响及其内在机制。

目的

本研究旨在探讨年轻人睡眠拖延的远因因素，即童年环境风险（严酷性和不可预测性）与睡眠拖延之间的关系，以及生活史（LH）策略和控制感的中介作用。

参与者和设置

通过方便抽样，453 名年龄在 16 至 24 岁的中国大学生（55.2%为男性，M=21.21 岁）完成了关于人口统计学、童年环境严酷性（来自社区、学校和家庭）和不可预测性（父母离婚、家庭搬迁和父母就业变化）、LH 策略、控制感和睡眠拖延的问卷。

方法

使用结构方程模型检验假设模型。

结果

结果表明，童年环境的严酷性和不可预测性都与睡眠拖延呈正相关。控制感在严酷性与睡眠拖延之间（B=0.02，95%CI=[0.004，0.042]）和不可预测性与睡眠拖延之间（B=0.01，95%CI=[0.002，0.031]）都具有部分中介作用。LH 策略和控制感在严酷性与睡眠拖延之间（B=0.04，95%CI=[0.010，0.074]）和不可预测性与睡眠拖延之间（B=0.01，95%CI=[0.003，0.029]）都具有序列中介作用。
