The purpose of this study was to develop and validate the Communication Behavior Scale for nurses caring for people with Dementia (CBS-D).

Based on communication accommodation theory, the initial items were generated through a literature review and interviews with 20 experts. Content and face validity of the initial items were assessed. Data from 486 nurses caring for people with dementia were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion-related validity, and internal consistency.

The final scale consisted of 18 items and four factors (discourse response management, interpersonal control, emotional expression, and interpretability) that explained 57.6% of the variance. Confirmatory factor analysis indicated that the theoretical model with 18 items satisfied all goodness-of-fit parameters. Criterion-related validity was shown by the Global Interpersonal Communication Competence Scale (r=.506, p<.001). Cronbach's alpha for the total scale was .88.

The CBS-D can be used to measure the communication behavior of nurses caring for people with dementia.

To validate the Korean Version of the Jefferson Empathy Scale for Health professionals (K-JSE-HP) in a sample of Korean nurses.

Internal consistency reliability, construct and criterion validity were calculated using SPSS (22.0) and AMOS (22.0). Data were collected from 253 nurses (230 women, 23 men) working at one university hospital in Seoul, South Korea.

The Korean version of JSE-HP showed reliable internal consistency with Cronbach's alpha for the total scale of .89, and .74~.84 for subscales. The model of three subscales for the K-JSE-HP was validated by confirmatory factor analysis (χ²=864.60, Q=6.55, p<.001, CFI=.94, NNFI=.92). Criterion validity compared to the Interpersonal Reaction Index (IRI) showed significant correlation.

The findings of this study demonstrate that the Korean JSE-HP shows satisfactory construct and criterion validity and reliability. It is a useful tool to measure Korean nurses' empathy.
