Aims and objectives:To detect the mediating effect of resilience on the relationship between perceived social support and burnout in Chinese palliative nurses.Background: Palliative nurses are a group that is vulnerable to burnout. Perceived social support may contribute to decreasing palliative nurses' burnout and facilitating their personal resilience, and resilience may be associated with lower levels of burnout. However, these relationships were unclear in the Chinese context. Design:A cross-sectional design. Methods:The STROBE guideline was performed to report this study. A mixed sampling method including convenience sampling and stratified sampling was used to recruit participants, and a total of 319 palliative nurses completed the Nursing Burnout Scale, the Perceived Social Support Scale and the Connor-Davidson Resilience Scale from May 2021 to September 2021. Influencing factors were primarily identified using independent-sample t tests and one-way ANOVA. Bootstrap method was used to detect the mediating effect of resilience. Results:The level of burnout in palliative nurses (23.4 ± 7.68) was higher than that of general nurses in China. Education level, health condition and monthly income were influencing factors of burnout. Resilience was detected as a mediator in the relationships between perceived social support and dimensions of burnout. Conclusions: Chinese palliative nurses experience a relatively high level of burnout, which may be influenced by several sociodemographic variables. Resilience could mediate the effect of perceived social support on the dimensions of burnout. Problemoriented and palliative-tailored strategies should be developed to further address burnout in Chinese palliative nurses. Relevance to clinical practice: Nurse managers and policy makers should support nurse ongoing education, adopt health-promoting interventions and optimise salary systems. In addition, perceived social support resources and resilience training programmes are also warranted.

BackgroundCurrent studies have revealed that acceptance and commitment therapy (ACT) can alleviate the adverse effects of cancer; however, its effectiveness on the psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer remains unclear.AimsThe aims of this study were to identify the effectiveness of ACT on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer, and to explore moderators.MethodsPubMed, Embase, Web of Science, CENTRAL, PsycINFO, CINAHL, CNKI, VIP, and Wanfang electronic databases were searched from inception to September 29, 2022. The Cochrane Collaboration's risk‐of‐bias assessment tool II and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to evaluate evidence certainty. The data were analyzed using R Studio. The study protocol was registered with PROSPERO (CRD42022361185).ResultsThe study included 19 relevant studies (1643 patients) published between 2012 and 2022. The pooled results showed that ACT significantly improved psychological flexibility (mean difference [MD] = −4.22, 95% CI [−7.86, −0.58], p = .02) and quality of life (Hedges' g = 0.94, 95% CI [0.59, 1.29], Z = 5.31, p < .01) but did not significantly improve fatigue (Hedges' g = −0.03, 95% CI [−0.24, 0.18], p = .75) or sleep disturbance (Hedges' g = −0.26, 95% CI [−0.82, 0.30], p = .37) in patients with cancer. Additional analyses revealed a 3‐month sustainable effect on psychological flexibility (MD = −4.36, 95% CI [−8.67, −0.05], p < .05), and moderation analysis showed that intervention duration (β = −1.39, p < .01) and age (β = 0.15, p = .04) moderated the effects of ACT on psychological flexibility and sleep disturbance, respectively.Linking Evidence to ActionAcceptance and commitment therapy demonstrates effectiveness for psychological flexibility and quality of life of patients with cancer, but there is a lack of evidence regarding its effects on fatigue and sleep disturbance. In clinical practice, ACT should be designed in more detail and rounded to achieve better results.
