目的 探讨人-工作匹配和自我效能感在护理实习生感知指导与工作绩效间的中介作用。方法 采用感知指导量表、人-工作匹配量表、自我效能感量表以及工作绩效量表对2021年广东省5家三级甲等医院384名护理实习生进行调查。结果 护理实习生感知指导条目均分为(5.27±1.16)分,人-工作匹配条目均分为(4.57±1.23)分,自我效能感条目均分为(4.89±1.07)分,工作绩效条目均分为(4.62±1.13)分。护理实习生感知指导、人-工作匹配、自我效能感能正向预测工作绩效,共同解释工作绩效变异的71.9%;护理实习生感知指导通过人-工作匹配、自我效能感的中介作用正向预测工作绩效,中介作用效应值分别为0.349 8和0.033 9;护理实习生感知指导通过人-工作匹配,经自我效能感的链式中介作用正向预测工作绩效,中介作用效应值为0.068 7。结论 人-工作匹配和自我效能感在护理实习生感知指导和工作绩效之间起链式中介作用。 相似文献

Subarachnoid hemorrhage (SAH) survivors often experience sleep disturbances. Self-efficacy for managing chronic disease may impact sleep for SAH survivors; however, little is known about the relationship between self-efficacy and subjective and objective sleep measures. The purpose of this study was to examine the associations among self-efficacy and subjective (nighttime sleep quality and daytime sleepiness) and objective (total sleep time [TST], wake after sleep onset [WASO], and sleep efficiency [SE]) sleep measures in SAH survivors. A cross-sectional study with a convenience sample of 30 SAH survivors was conducted. Self-efficacy was assessed with the Self-Efficacy for Managing Chronic Disease scale. Nighttime sleep quality and daytime sleepiness were assessed with the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale, respectively. SAH survivors wore a wrist actigraph for 7 days to estimate TST, WASO, and SE. Analyses revealed that, within 3 months post-SAH, 73% of SAH survivors experienced poor sleep quality and 27% reported excessive daytime sleepiness. In addition, 41.4% of the participants slept on average either < 7 h or > 9 h. Self-efficacy was correlated with nighttime sleep quality (r = -0.394, p = .031) and SE (r = 0.412, p = .026), but not with daytime sleepiness (r = -0.257, p = .170), TST (r = 0.137, p = .447), or WASO (r = -0.223, p = .246). Sleep disturbances are prevalent in SAH survivors. Targeted interventions focused on self-efficacy and self-management behaviors in this population may improve sleep and lead to better health. 相似文献

Objective . To examine relationships among changes in self-efficacy and changes in other clinically relevant outcome measures. Method . Subjects (n = 44) were participants in a prospective, randomized stress-management study followed over 15 months. Outcome measures included self-efficacy, depression, pain, health status, and disease activity. Results . Correlational analyses revealed significant associations between changes in self-efficacy (particularly total self-efficacy) and changes in selected measures of depression, pain, health status, and disease activity. The observed associations were not due to changes in medication regimen or to nonadherence to the stress-management program. Conclusions . Evidence is provided that induced changes in self-efficacy following a stress-management program were significantly related to other clinically important outcome measures. 相似文献

Objective . To examine how self-efficacy for arthritis pain relates to the perception of controlled laboratory pain stimuli. Methods . Forty patients with osteoarthritis completed self-report measures of self-efficacy for arthritis pain. They then participated in a single experimental session in which measures of thermal pain threshold and tolerance were collected, as well as measures of the perceived intensity and unpleasantness of a range of thermal pain stimuli. Results . Correlational analyses revealed that patients reporting high self-efficacy for arthritis pain rated the thermal pain stimuli as less unpleasant than those reporting low self-efficacy. When subjects scoring very high and very low in self-efficacy were compared, it was found that subjects scoring high on self-efficacy for arthritis pain had significantly higher pain thresholds and pain tolerance than those scoring low on self-efficacy. Conclusions . These results in dicate that self-efficacy for arthritis pain is related to judgments of thermal pain stimuli. Implications for the understanding of arthritis pain and for future laboratory research are discussed. 相似文献

目的探讨结构式心理干预在急性心肌梗死(AMI)患者中的应用效果。方法采用便利抽样法,选取驻马店市中心医院2016年1月—2019年10月收治的AMI患者196例为研究对象。按随机数字表法将其分为对照组(n=97)和观察组(n=99)。对照组患者行常规护理干预,观察组在对照组的基础上行结构式心理干预。采用一般自我效能感量表(GSES)、Barthel指数、SAS、SDS比较干预的效果。结果干预2个月后,观察组患者GSES评分、Barthel指数均高于对照组,差异有统计学意义(P<0.05)。干预2个月后,观察组患者SDS、SAS评分均低于对照组,差异有统计学意义(P<0.05)。结论结构式心理干预能够提高AMI患者自我效能,同时可缓解患者焦虑、抑郁等负性情绪,从而有助于改善预后。 相似文献
