Revisiting the impact of job satisfaction and organizational commitment on nurse turnover intention: an individual differences analysis

Background

Nurse turnover is an important contributing factor to the worldwide nursing shortage. Many studies have examined the antecedents of nurse turnover to gain a better understanding of the problem and help hospitals reduce their turnover rates. However, an important shortcoming of this research stream is its exclusive focus on explaining turnover behavior of the “average nurse”, thereby disregarding individual differences between nurses and groups of nurses.

Objectives

To examine individual differences in the relationships between two crucial turnover antecedents – job satisfaction and organizational commitment – and nurse turnover intention.

Participants

A sample of 287 nurses working for a variety of Belgian hospitals participated in the study.

Methods

A survey method was used to collect quantitative data, which were analyzed through standard multiple linear regression, mixture regression models and t-tests.

Results

In the total sample of hospital nurses, both job satisfaction and organizational commitment significantly predicted nurse turnover intention. However, subsequent individual differences analyses revealed the existence of two subgroups of nurses. In the satisfaction focused group, only job satisfaction was found to predict nurse turnover intention, whereas in the satisfaction and commitment focused group both job satisfaction and organizational commitment were related to turnover intention. Furthermore, nurses in the latter group displayed stronger turnover intention, were significantly younger and had less job tenure and organizational tenure than nurses in the satisfaction focused group.

Conclusions

The debate on the antecedents of nurse turnover still continues, as the existing models fail to fully grasp nurse turnover. The present study identifies individual differences in nurse turnover antecedents among groups of nurses as a possible reason for the absence of one comprehensive turnover model that holds for the general nursing population. Further studies are needed in order to capture the total impact of the underlying individual differences in nurse turnover antecedents.     

Cripto regulates skeletal muscle regeneration and modulates satellite cell determination by antagonizing myostatin

Skeletal muscle regeneration mainly depends on satellite cells, a population of resident muscle stem cells. However, our understanding of the molecular mechanisms underlying satellite cell activation is still largely undefined. Here, we show that Cripto, a regulator of early embryogenesis, is a novel regulator of muscle regeneration and satellite cell progression toward the myogenic lineage. Conditional inactivation of cripto in adult satellite cells compromises skeletal muscle regeneration, whereas gain of function of Cripto accelerates regeneration, leading to muscle hypertrophy. Moreover, we provide evidence that Cripto modulates myogenic cell determination and promotes proliferation by antagonizing the TGF-β ligand myostatin. Our data provide unique insights into the molecular and cellular basis of Cripto activity in skeletal muscle regeneration and raise previously undescribed implications for stem cell biology and regenerative medicine.     

中医医生职业承诺量表的结构模型评价研究

目的 确立中医医生的职业承诺结构模型.方法 通过访谈(18例)、开放式问卷(67例)等方法 ,编制职业承诺问卷;对324名中医医生进行预测,采用探索性因子分析对条目进行优化和因子提取,修订得到正式问卷;重新选取507名中医医生进行正式测试,通过对数据进行验证性因子分析(结构方程模型),对问卷结构进行模型验证,考察问卷结构效度;以转职意愿为效标,检验问卷的实证效度;问卷信度采用内部一致性系数检验.结果 探索性因子分析构建了4个维度共13个条目组成的中医医生职业承诺问卷,4个公因子的累积方差贡献率达61.437%,各条目的 因子负荷在0.591～0.861之间;验证性因子分析各项拟合度指标χ2/df、近似误差均方根(RMSEA)、拟合优度指数(GFI)、非范拟合指数(NNFI)、比较拟合指数(CFI)、省俭规范拟合指数(PNFI)分别为1.79、0.039、0.97、0.97、0.98、0.72;转职意愿与职业承诺各维度均呈显著性负相关关系(P<0.01);问卷及其各维度的Cronbach's α系数在0.602～0.847之间.结论 中医医生的职业承诺为四维结构,包括情感认同承诺、限制选择承诺、专业效能承诺和职业风险承诺;中医医生职业承诺问卷具有较好的信度和效度.     

不同类型生源高职护生的专业承诺水平比较

目的 了解不同类型生源高职护生的专业承诺水平。方法 采用大学生专业承诺量表对福建省某高职院校676名护生进行问卷调查。结果 676名高职护生专业承诺得分为(101±13.01)分,高中生源类型护生专业承诺得分(99.55±11.61)低于中职生源护生专业承诺得分(103.32±14.68),差异具有统计学意义(P＜0.05)。结论 高职护生专业承诺总体处于中等偏上水平,但高中生源护生的专业承诺水平低于中职生源护生,护理高职院校和教师应重点关注高中生源护生的专业思想,采取针对性的措施引导护生全面认识护理专业,稳定专业思想。     

接纳承诺疗法对糖尿病患者心理灵活性干预效果的Meta分析

摘 要 目的 系统评价接纳承诺疗法（ACT）对糖尿病患者心理灵活性及自我管理、焦虑抑郁情绪的干预效果。方法 通过查找Cochrane图书馆中心数据库、PubMed、Web of science（SCI）、Embase、ProQuest、CBM、CNKI、万方、维普数据库从建库至2022年8月ACT干预糖尿病患者心理灵活性的相关随机对照文献，进行质量评价并使用RevMan5.3进行数据分析。结果 纳入10篇随机对照试验，共685例研究对象。Meta分析结果显示：接纳承诺疗法能够提高糖尿病患者的心理灵活性［SMD=0.44，95%CI（0.17，0.70），P=0.001］和自我管理水平［SMD=0.40，95%CI（0.01，0.79），P=0.04］，降低糖化血红蛋白［MD=-1.07，95%CI（-1.77，-0.37），P=0.003］，在减轻抑郁焦虑等负性情绪上也有一定作用。结论 接纳承诺疗法一定程度上对于提高糖尿病患者的心理灵活性和自我管理水平，降低糖化血红蛋白，缓解抑郁焦虑等情绪方面是有效的。
