Validation of the Chinese Version of the Patient' s Communication Perceived Self-efficacy Scale (PCSS) in Out Patients after Total Hip Replacement
Abstract Background: Among older patients worldwide, communication has become an important public health issue in the world. This communication could be improved by different interventions. However, a tool of measuring patients’ confidence in communication with doctors has not been established in China. This study is aimed at translating and introducing the Patient's Communication Self-Efficacy Scale for assessing communication between doctors and elderly patients.Method: (1) A post-consultation questionnaire was completed by 167 patients (mean age = 70.04 years; SD: 6.3 years; females/males: 94/73). The researchers translated the English version PCSS into Chinese under the guidance of the original author. (2) The final Chinese version of the PCSS was validated. Measurement indices included item generation, reliability testing, construct validity and test-retest reliability. To carry out the above tests, we used SPSS 19.0 software and LISREL 8.7. We built the Bayesian network model of the Chinese version of the PCSS and determined predictive variables.Result: Confirmatory factor analysis showed that the Chinese version of the PCSS fit a three-dimensional model. Additionally, the Chinese version of the PCSS has high internal consistency (Cronbach’s α coefficient 0.929) and test-retest reliability (Kappa coefficient 0.761). The Bayesian networks shows that the important predictors are education (0.4207), PEPPI 3 (0.3951), and PCSS 1 (0.1139). The connections between PCSS 3 and other variables do not indicate causality but rather conditional dependencies or interrelatedness.Conclusion: This is the first study to validate the Chinese version of the PCSS in outpatients after total hip replacement. Our results confirmed that the Chinese version of the scale has high internal consistency, construct validity and test-retest reliability. Patient-doctor interaction and education are important predictors of patient communication self-efficacy.
