Abstract

Rationale

Powerlessness is a negative perception that can affect all people throughout their lives. Individuals are particularly vulnerable in times of illness and are prone to experience powerlessness. It is therefore important to learn about powerlessness, recognize the symptoms and take action.

Aims and Objectives

This study aimed to develop a measurement tool that can evaluate the powerlessness of patients.

Methods

In this methodological study, face and content validity, construct validity and reliability analyses were examined to develop the scale and determine its psychometric properties. The scale's psychometric properties were tested with 1044 nurses and patients in different sample groups. Data were collected between 22 November 2022 and 2 December 2023.

Results

The content validity index of the scale is 0.75. According to principal components analysis, the scale consisted of 24 items and four sub-dimensions. The total variance of the scale was 64.62%, and the factor loading values were in the range of 0.649−0.882. In confirmatory factor analysis, fit indices were acceptable or good. According to the reliability analysis, the scale's reliability is high. Test−retest showed that the scale made stable measurements over time.

Conclusion

In conclusion, the patient powerlessness assessment scale is a valid and reliable measurement tool for patients and nurses.

无力感评定量表的编制与心理测试

无力感是一种消极的感觉，会影响所有人的一生。个人在生病时特别脆弱，容易感到无力。因此，了解无力感，认识到症状并采取行动是很重要的。目的与目的本研究旨在开发一种能够评估患者无力感的测量工具。方法采用面效度、内容效度、结构效度和信度分析等方法编制量表，确定量表的心理测量特性。对1044名不同样本组的护士和患者进行了量表的心理测量特性测试。数据收集于2022年11月22日至2023年12月2日之间。结果量表的内容效度指数为0.75。根据主成分分析，量表由24个条目和4个子维度组成。量表的总方差为64.62%，因子负荷值在0.649 ~ 0.882之间。验证性因子分析的拟合指标为可接受或良好。经信度分析，该量表的信度较高。反复测试表明，随着时间的推移，该秤的测量结果是稳定的。结论患者无力感量表对患者和护士来说是一种有效、可靠的测量工具。

期刊介绍： The Journal of Evaluation in Clinical Practice aims to promote the evaluation and development of clinical practice across medicine, nursing and the allied health professions. All aspects of health services research and public health policy analysis and debate are of interest to the Journal whether studied from a population-based or individual patient-centred perspective. Of particular interest to the Journal are submissions on all aspects of clinical effectiveness and efficiency including evidence-based medicine, clinical practice guidelines, clinical decision making, clinical services organisation, implementation and delivery, health economic evaluation, health process and outcome measurement and new or improved methods (conceptual and statistical) for systematic inquiry into clinical practice. Papers may take a classical quantitative or qualitative approach to investigation (or may utilise both techniques) or may take the form of learned essays, structured/systematic reviews and critiques.
