To test the predictive value and convergent construct validity of a 6-item work functioning screener (WFS-H).
Healthcare workers (249 nurses) completed a questionnaire containing the work functioning screener (WFS-H) and a work functioning instrument (NWFQ) measuring the following: cognitive aspects of task execution and general incidents, avoidance behavior, conflicts and irritation with colleagues, impaired contact with patients and their family, and level of energy and motivation. Productivity and mental health were also measured. Negative and positive predictive values, AUC values, and sensitivity and specificity were calculated to examine the predictive value of the screener. Correlation analysis was used to examine the construct validity.
The screener had good predictive value, since the results showed that a negative screener score is a strong indicator of work functioning not hindered by mental health problems (negative predictive values: 94%-98%; positive predictive values: 21%-36%; AUC:.64-.82; sensitivity: 42%-76%; and specificity 85%-87%). The screener has good construct validity due to moderate, but significant (p<.001), associations with productivity (r=.51), mental health (r=.48), and distress (r=.47).
The screener (WFS-H) had good predictive value and good construct validity. Its score offers occupational health professionals a helpful preliminary insight into the work functioning of healthcare workers.
检验一个包含6个条目的工作功能筛查工具（WFS-H）的预测价值和聚合效度。
医护人员（249名护士）完成了一份问卷，其中包含工作功能筛查工具（WFS-H）和一个工作功能量表（NWFQ），该量表测量以下方面：任务执行的认知方面和一般事件、回避行为、与同事的冲突和恼怒、与患者及其家属接触受损，以及精力和动力水平。还测量了工作效率和心理健康状况。计算阴性和阳性预测值、AUC值、敏感性和特异性，以检验筛查工具的预测价值。采用相关分析检验结构效度。
该筛查工具具有良好的预测价值，因为结果显示筛查工具得分为阴性是工作功能未受心理健康问题阻碍的有力指标（阴性预测值：94%-98%；阳性预测值：21%-36%；AUC：0.64-0.82；敏感性：42%-76%；特异性：85%-87%）。由于与工作效率（r = 0.51）、心理健康（r = 0.48）和困扰（r = 0.47）存在中等但显著（p <.001）的关联，该筛查工具具有良好的结构效度。
筛查工具（WFS-H）具有良好的预测价值和结构效度。其得分可为职业健康专业人员提供关于医护人员工作功能的有益初步见解。
