To assess intensive care nurses' resilience and identify associated personal factors and physical activity behaviours using a job demands-recovery framework.
Currently, there is inconsistent evidence as to whether nurse resilience is associated with personal factors or with physical activity at work or during leisure time.
A cross-sectional study was conducted with nurses from four intensive care units in Auckland, New Zealand.
An online survey was conducted to collect nurses' personal information and assess their resilience levels using the Connor-Davidson Resilience Scale 25. Participants were nurses working at least 32 hr fortnightly and providing direct patient care. Physical activity was objectively measured using a pair of accelerometers worn on the back and thigh over four consecutive days (two workdays followed by two nonworkdays). Bivariable and multivariable regression were used to identify personal factors and physical activity behaviours associated with resilience (followed the STROBE checklist).
A total of 93 nurses were included in the study. The participants' average resilience level was low. Resilience was positively associated with the objectively measured physical job demands factors: occupational physical activity, moderate-to-vigorous physical activity at work and dynamic standing at work. Resilience was negatively associated with one objectively measured recovery factor: sleep during leisure time. In multivariable modelling, being married and moderate-to-vigorous physical activity at work were positively associated with resilience, while not having religious beliefs and sleep during leisure time were negatively associated with resilience.
Resilient nurses have a greater tolerance to high physical activity at work and lower sleep duration during leisure time. Strategies are needed to improve intensive care nurses' resilience levels.
Results may help managers gain a better understanding of the ICU nurses' characteristics associated with resilience, leading them to develop strategies for improving ICU nurse resilience.
使用工作需求-恢复框架评估重症监护护士的韧性，并确定相关的个人因素和身体活动行为。
目前，关于护士韧性是否与个人因素或工作时或闲暇时的身体活动有关，证据尚不一致。
这是一项在新西兰奥克兰的四个重症监护病房进行的横断面研究。
通过在线调查收集护士的个人信息，并使用 Connor-Davidson 韧性量表 25 评估他们的韧性水平。参与者是每周至少工作 32 小时并提供直接患者护理的护士。使用戴在后背上和大腿上的一对加速度计在连续四天（两个工作日后接着两天非工作日）内客观测量身体活动。使用单变量和多变量回归来确定与韧性相关的个人因素和身体活动行为（遵循 STROBE 清单）。
共有 93 名护士参与了研究。参与者的平均韧性水平较低。韧性与客观测量的体力工作需求因素呈正相关：职业体力活动、工作时的中等到剧烈体力活动以及工作时的动态站立。韧性与一个客观测量的恢复因素呈负相关：闲暇时的睡眠时间。在多变量模型中，已婚和工作时的中等到剧烈体力活动与韧性呈正相关，而没有宗教信仰和闲暇时的睡眠时间与韧性呈负相关。
有韧性的护士对工作时的高强度体力活动和闲暇时的低睡眠时间有更强的耐受性。需要采取策略来提高重症监护护士的韧性水平。
结果可能有助于管理人员更好地了解与韧性相关的重症监护护士的特征，从而制定提高重症监护护士韧性的策略。
