The purpose of this study was to assess the psychometric properties of the Control Over Nursing Practice Scales using data from registered nurses (N = 1117) employed in four acute care hospitals in the Midwest. Psychometric evaluation included dimensional analysis, reliability estimation, and validity assessment of six dimensions of a 33-item instrument: responsibility and influence of head nurses, staff nurses, and committees; access to ideas; use of personal resources; and research utilization. Factor analysis reproduced six dimensions that explained 61% of the variance. Coefficient alphas ranged from .75-.89. Correlations between Control Over Nursing Practice with autonomy, group cohesion, job stress, and job satisfaction supported construct validity. Empirical testing of known group differences to obtain new information about the construct revealed that critical care nurses scored higher on research utilization than medical-surgical or obstetrical nurses; baccalaureate-prepared nurses scored higher than associate or diploma nurses on responsibility and influence: committees. Contrary to our hypothesis, there were no differences between part-time and full-time nurses on any of the six dimensions.
本研究的目的是利用来自中西部四家急症护理医院的注册护士(N = 1117)的数据,评估护理实践控制量表的心理测量特性。心理测量评估包括维度分析、信度估计以及对一个包含33个条目的工具的六个维度进行效度评估:护士长、护士以及委员会的职责与影响力;获取想法的途径;个人资源的利用;以及研究应用。因子分析重现了六个维度,这些维度解释了61%的方差。系数阿尔法值范围为0.75 - 0.89。护理实践控制与自主性、团队凝聚力、工作压力和工作满意度之间的相关性支持了结构效度。对已知组间差异进行实证检验以获取有关该结构的新信息,结果显示重症护理护士在研究应用方面的得分高于内科 - 外科或产科护士;拥有学士学位的护士在职责与影响力:委员会方面的得分高于拥有副学士学位或文凭的护士。与我们的假设相反,兼职护士和全职护士在六个维度中的任何一个维度上均无差异。
