Development and Psychometric Testing of Powerlessness Assessment Scale for Patients
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.
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.
