Psychometric Evaluation of the Chinese Version of the Patient Perceptions of Empowerment Scale (PPES)‎

Abstract EN

Objectives.

To evaluate the psychometric properties of the Chinese version of the Patient Perceptions of Empowerment Scale (PPES) and to perform a cross-cultural validity assessment.

Methods.

In this cross-sectional survey, 554 inpatients in three general hospitals in northern Taiwan were recruited.

Principal component analysis was used to examine the factor structure of the scale.

Confirmatory factor analyses were conducted on the measurement model of the Chinese version of the PPES.

Results.

Confirmatory factor analyses supported the presence of a second-order four-factor model (information, decision, individual, and self-management) of the Chinese version of the PPES when used with a Taiwanese inpatient population.

The results indicate that the 11-item, second-order, four-factor Chinese version of the PPES provided best goodness-of-fit for the data in this study.

Conclusion.

The 11-item four-factor Chinese version of the PPES is a self-completion scale.

This study demonstrated that the Chinese version of the PPES is a reliable and valid self-report instrument for the assessment of patient perceptions of empowerment in clinical practice.

Further adaptation and evaluation of the scale will hopefully stimulate further studies on PPES in the fields of psychometrics in Taiwan.
