Abstract

BACKGROUND

There is a lack of an acceptable, reliable, and valid survey instruments to differentiate levels of nursing teamwork on inpatient units in acute care facilities.

OBJECTIVE

The aim of this study was to test the psychometric soundness of the Nursing Teamwork Survey (NTS).

METHODS

The survey was administered to 1,758 inpatient nursing staff members using the NTS (return rate = 56.9%), and measures of content, predictive (concurrent), and construct (factorial, contrast, and convergent) validity were completed.

RESULTS

Content validity was established by a panel of experts. Concurrent validity showed a significant correlation between teamwork scores and an imbedded question related to overall satisfaction with teamwork (r = .633, p < .001). The exploratory factor analysis on a random half of the sample predicted a 33-item five-factor solution, whereas the confirmatory factor analysis on the remaining half of the sample confirmed the factor structure (comparative fit index = .884, root mean square error of approximation = 0.055, standardized root mean square residual = 0.045). Contrast validity showed that staff in a non-inpatient unit did not answer the questions in the same way (rWG(J) = .25) as the inpatient unit staff (rWG(J) > .90). Convergent validity of the teamwork tool was measured by correlating the Teamwork subscale of the Safety Attitudes Questionnaire with the NTS (r = .76, p < .01). The NTS had good test-retest reliability (r = .92 for overall 33 items; r = .77 to.87 for the five subscales) and internal consistency (alpha = .94 for overall items; alpha = .74 to.85 for the subscales). Aggregation of individual-level responses to the unit level was supported by intraclass correlation coefficient 1 = .16 (p < .001), intraclass correlation coefficient 2 = .9 (p < .001), and mean rWG(J) = .98.

DISCUSSION

The NTS was demonstrated to have good psychometric properties. Further NTS research should include testing the tool in hospitals with varying characteristics and exploring the links to clinical and operational outcomes.

摘要

背景

目前缺乏一种可接受、可靠和有效的调查工具来区分急症护理机构中住院病房的护理团队协作水平。

目的

本研究旨在检验护理团队调查（NTS）的心理测量学特性。

方法

使用 NTS 对 1758 名住院护理人员进行调查（回收率=56.9%），并完成内容、预测（同期）和结构（因子、对比和收敛）有效性的测量。

结果

内容有效性由专家组确定。同期有效性显示，团队合作评分与一项与团队合作总体满意度相关的嵌入式问题之间存在显著相关性（r=.633，p<.001）。对样本随机一半的探索性因子分析预测了 33 项 5 因素解决方案，而对样本另一半的验证性因子分析则证实了该因子结构（比较拟合指数=.884，均方根误差近似值=0.055，标准化均方根残差=0.045）。对比有效性表明，非住院病房的员工回答问题的方式与住院病房的员工不同（rWG（J）=.25）（rWG（J）>.90）。通过将安全态度问卷的团队合作子量表与 NTS 相关联，来衡量团队合作工具的收敛有效性（r=.76，p<.01）。NTS 具有良好的重测信度（33 项总分的 r=.92；五个子量表的 r=.77 至.87）和内部一致性（总分的α=.94；五个子量表的α=.74 至.85）。个体层面的响应在单位层面的聚合得到了组内相关系数 1 =.16（p<.001）、组内相关系数 2 =.9（p<.001）和平均 rWG（J）=.98 的支持。
