Poor sleep confers significant morbidities and is highly prevalent among college students in the United States. This research assessed sleep quality and its association with health-related quality of life (HRQOL). Further, because sleep quality research often lacks a theoretical foundation, we applied a theoretical model using selected constructs from the Theory of Planned Behavior (TPB) and Health Belief Model (HBM). A random, stratified sample of undergraduate students participated in an online survey (N = 494). Structural equation modeling assessed the association between theoretical constructs, sleep quality, and HRQOL. The final model fit was acceptable, with ~ 20% of the variance in sleep quality explained by the theoretical constructs and control variables. HBM constructs were indirectly and negatively related to sleep quality, mediated through behavioral intention, and also positively and directly associated with behavioral intention. Behavioral intention was strongly and negatively associated with sleep quality. Approximately 31% of the variance in HRQOL was explained by poor sleep quality, behavioral intention, and gender. Poor sleep was most strongly associated with reduced HRQOL. HBM constructs and behavioral intention from TPB were significantly associated with poor sleep quality, and poor sleep was significantly related to poor HRQOL.
睡眠质量差会导致严重的疾病，而且在美国的大学生中非常普遍。本研究评估了睡眠质量及其与健康相关生活质量（HRQOL）的关系。此外，由于睡眠质量研究通常缺乏理论基础，我们应用了一个理论模型，该模型使用了计划行为理论（TPB）和健康信念模型（HBM）中的选定结构。一个随机的、分层的本科生样本参与了在线调查（N=494）。结构方程模型评估了理论结构、睡眠质量和 HRQOL 之间的关联。最终模型拟合度可接受，理论结构和控制变量解释了睡眠质量约 20%的方差。HBM 结构通过行为意向间接且负相关，并与行为意向呈正相关且直接相关。行为意向与睡眠质量呈强烈负相关。大约 31%的 HRQOL 方差由睡眠质量差、行为意向和性别解释。睡眠质量差与 HRQOL 降低的关系最密切。HBM 结构和 TPB 的行为意向与睡眠质量差显著相关，而睡眠质量差与 HRQOL 差显著相关。
