BACKGROUND
Adequate staffing is crucial for high quality patient care and nurses' wellbeing. Nurses' professional assessment on adequacy of staffing is the gold standard in measuring staffing adequacy. However, available measurement instruments lack reliability and validity.
OBJECTIVES
To develop and psychometrically test an instrument to measure nurses' perceived adequacy of staffing (PAS) of general hospital wards.
DESIGN
A multicenter cross-sectional psychometric instrument development and validation study using item response theory.
SETTINGS
Ten general nursing wards in three teaching hospitals in the Netherlands.
PARTICIPANTS
A sample of 881 participants, including third and fourth year nursing students and nurse/care assistants.
METHODS
The 13-item self-reported questionnaire was developed based on a previous Delphi study and two focus groups. We interviewed five nurses to evaluate the content validity of the instrument. The field test for psychometric evaluation was conducted on ten general wards of three teaching hospitals in the Netherlands. Structural validity of the item bank was examined by fitting a graded response model (GRM) and inspecting GRM fit. Measurement invariance was assessed by evaluating differential item functioning (DIF) of education level and work experience. We examined convergent validity by testing the hypothesis that there was at least a moderate correlation between the PAS instrument and a single item measuring adequacy of staffing. Internal consistency and reliability across the scale were also examined.
RESULTS
A total of 881 measurements were included in the analysis. The data fitted the GRM adequately and item fit statistics were good. DIF was detected for work experience for the protocols item, but the impact on total scores was negligible. The hypothesis was confirmed and the item bank reliably measured two standard deviations around the mean.
CONCLUSIONS
The Nurse Perceived Adequacy of Staffing Scale (NPASS) for nurses of general hospital wards in the Netherlands has sufficient reliability and validity and is ready for use in nurse staffing research and practice.
背景
充足的人员配备对于高质量的患者护理和护士的福祉至关重要。护士对人员配备充足性的专业评估是衡量人员配备充足性的金标准。然而，现有的测量工具缺乏可靠性和有效性。
目的
开发并进行心理测量学测试一种工具，以测量综合医院病房护士对人员配备充足性的感知（PAS）。
设计
一项使用项目反应理论的多中心横断面心理测量工具开发与验证研究。
设置
荷兰三家教学医院的十个普通护理病房。
参与者
881名参与者的样本，包括大三和大四护理专业学生以及护士/护理助理。
方法
基于先前的德尔菲研究和两个焦点小组开发了一份包含13个条目的自填式问卷。我们采访了五名护士以评估该工具的内容效度。在荷兰三家教学医院的十个普通病房进行了心理测量评估的现场测试。通过拟合分级反应模型（GRM）并检查GRM拟合来检验题库的结构效度。通过评估教育水平和工作经验的项目功能差异（DIF）来评估测量不变性。我们通过检验PAS工具与一个测量人员配备充足性的单项之间至少存在中等相关性的假设来检验收敛效度。还检查了量表的内部一致性和可靠性。
结果
分析共纳入881次测量。数据充分拟合GRM且项目拟合统计良好。在方案项目中检测到工作经验的DIF，但对总分的影响可忽略不计。该假设得到证实，题库可靠地测量了均值周围两个标准差的范围。
结论
荷兰综合医院病房护士的护士人员配备充足性感知量表（NPASS）具有足够的可靠性和有效性，可用于护士人员配备研究和实践。
