This study investigated whether the relationship between neuroticism and sleep quality in nursing interns is mediated by traditional Chinese medicine (TCM) constitution. In addition, the study examined whether sedentary behaviour affects this mediating model.
The importance of sleep quality for nursing interns cannot be overstated. Previous studies have demonstrated that neuroticism negatively affects sleep quality. However, little is known about the path of the relationship between neuroticism and sleep quality among nursing interns.
A cross-sectional study was conducted in Central and South China.
A total of 630 nursing interns participated in this study. Neuroticism, TCM constitution, sleep quality, and sedentary behaviour were measured using reliable and valid questionnaires. Data were analysed using the PROCESS macro in SPSS.
Neuroticism significantly predicted the Pittsburgh Sleep Quality Index (PSQI; β = 0.144, P < 0.001). Neuroticism exerted a significant indirect effect on the PSQI through gentleness and damp heat constitution (β = 0.265, 95 % CI [0.214, 0.315]). In addition, sedentary time moderated this mediation model. Sedentary time marginally moderated the direct pathway from neuroticism to the PSQI (B = -0.025, 95 % CI [-0.046, -0.004]) and the pathway from neuroticism to the damp heat constitution (B = 0.175, 95 % CI [0.021, 0.329]) in the nursing interns.
TCM constitution mediates the relationship between neuroticism and sleep quality. Given the moderating effect of sedentary behaviour, targeting sedentary behaviour can be an effective approach to improve the sleep quality of nursing interns.
本研究调查中医体质是否介导护理实习生神经质与睡眠质量之间的关系。此外，本研究还考察了久坐行为是否会影响这一中介模型。
睡眠质量对护理实习生的重要性再怎么强调也不为过。以往研究表明，神经质会对睡眠质量产生负面影响。然而，对于护理实习生中神经质与睡眠质量之间关系的路径，人们知之甚少。
在中国中部和南部地区进行了一项横断面研究。
共有630名护理实习生参与了本研究。使用可靠且有效的问卷对神经质、中医体质、睡眠质量和久坐行为进行测量。数据采用SPSS中的PROCESS宏进行分析。
神经质显著预测匹兹堡睡眠质量指数（PSQI；β = 0.144，P < 0.001）。神经质通过平和质和湿热质对PSQI产生显著的间接效应（β = 0.265，95%CI [0.214, 0.315]）。此外，久坐时间调节了这一中介模型。久坐时间对护理实习生中从神经质到PSQI的直接路径（B = -0.025，95%CI [-0.046, -0.004]）以及从神经质到湿热质的路径（B = 0.175，95%CI [0.021, 0.329]）有微弱的调节作用。
中医体质介导了神经质与睡眠质量之间的关系。鉴于久坐行为的调节作用，针对久坐行为可能是改善护理实习生睡眠质量的有效方法。
