ABSTRACT
BACKGROUND: Patient engagement is considered a critical factor in improving healthcare delivery. This study aimed to test the Korean version of the Clinician Support for Patient Activation Measure (CS-PAM) using Rasch analysis, and to explore nurses' beliefs about patient self-management. METHODS: A cross-sectional, exploratory study design was employed. The staff nurses who were recruited from six hospitals were requested to complete the Korean CS-PAM. Their responses were subsequently subjected to Rasch analysis to validate the Korean CS-PAM. The CS-PAM was paraphrased into Korean using the standardized forward-backward translation method. RESULTS: The internal consistency of the scale had good Cronbach's alpha value. For all items, the infit and outfit statistics fell well within the acceptable range of 0.5-1.5. This measure formed a unidimensional Guttman-like scale that explained 54.7% of the variance. CONCLUSIONS: The Korean version of the CS-PAM showed good psychometric properties and appeared to be consistent with the meaning of the original CS-PAM. However, the items have a somewhat different ranking order when compared to the English and Dutch versions. The instrument might be useful for identifying the supportive beliefs and attitudes of nurses or healthcare providers in order to improve patient activation in healthcare.
ABSTRACT
OBJECTIVE: The Cancer-chemotherapy Concerns Rating Scale was developed in Japan for outpatients undergoing chemotherapy, and its validity and reliability have been reported. The purpose of the study was to test the reliability and validity of the Korean version of the Cancer-chemotherapy Concerns Rating Scale. METHODS: The questionnaire was filled out by 199 cancer patients, who were currently undergoing outpatient chemotherapy. The data were analyzed using exploratory factor analysis with Promax Rotation to determine the factor construct validity. The reliability of the Cancer-chemotherapy Concerns Rating Scale was investigated by Cronbach's alpha and the Spearman Brown coefficient. RESULTS: Four factors were obtained and the overall structure was similar to that of the Japanese version; reorganization of daily life, self-existence, disease progress, and social and economic concerns. Cronbach's alpha for the total scale was 0.91 and the Spearman Brown coefficient was 0.85. CONCLUSIONS: We found that the Korean version of the Cancer-chemotherapy Concerns Rating Scale could be clinically useful. It could provide health-care providers with information useful to understand the psychological state of patients undergoing outpatient chemotherapy.
