Abstract
The purpose of this study was to develop and validate tool for measuring the communication skills of dental hygienist. The survey was modified and revised to fit into Korean culture. Also the reliability and validity was tested in order to ensure the survey was properly evaluating communication skills of dental hygienists. A survey was conducted with outpatients in dental clinics located in Seoul, Gyeonggi, and Daejeon area. The 483 answers out of the total collected answers were used for the final analysis of the study, using PASW Statistics 18.0 and IBM SPSS AMOS 7.0 to measure the validity and reliability. The factor analysis showed that the communication skill of the dental hygienists was composed of three elements, namely 'being caring and respectful' communications, 'sharing information' communications and 'tending to comfort' communications to reduce pain and anxiety. The validity of the model examined by a confirmatory factor analysis satisfied most of the relevant requirements. All of the factors had the conceptual reliability and variant extracted index above the minimum requirements, ensuring reliability and concentrated validity. Also, the value of the square of the correlations between all latent factors which was larger than the square of the correlation between all of the factors, thus proving the discriment validity. Cronbach's ${\alpha}$ was 0.8, which shows high reliability level. In conclusion, it was proven that dental hygienist's communication skill measurement tool has high validity and reliability. Further, this study can be used to improve dental hygienists' communication skills. Therefore, this will improve oral health of clients and manage them.
1. 커뮤니케이션 기술 측정도구 38문항을 번역한 후 번역 정확도, 내용분석, 내용타당도 분석을 통하여 14문항을 수정하고, 10문항을 삭제하였으며, 팀 구성원 커뮤니케이션 4문항은 연구목적에 맞지 않아 제외하여 최종 커뮤니케이션 기술 측정도구는 총 24문항으로 구성되었다. 2. 수정 보완된 커뮤니케이션 기술 측정도구의 요인분석 결과 치과위생사의 커뮤니케이션 기술은 배려와 존중, 정보 제공, 불안과 통증 감소를 위한 커뮤니케이션 등 3개의 항목으로 구분되었다. 3. 확인적 요인분석을 통한 모형의 적합도는 대체로 기준을 충족하였으며 ($X^2=899.170$ [df=227, p<0.001], RMR=0.025, RMSEA=0.078, IFI=0.886, TLI=0.872, CFI= 0.886, GFI=0.848, AGFI=0.815, NFI=0.853) 모든 요인의 개념신뢰도, 분산추출지수가 일반적 기준을 충족시켜 집중타당성이 입증되었다. 모든 요인의 평균분산추출값은 각 요인간상관 관계 제곱값보다 크게 나타나 판별타당성도 입증되었다. 4. 내적일관성을 알아보기 위한 Cronbach's ${\alpha}$는 0.8 이상으로 높은 신뢰수준으로 나타났다. 이상의 결과를 종합해 보았을 때, 치과위생사의 커뮤니케이션 측정도구는 타당도와 신뢰도가 높고 적합하다고 검증되었다. 향후 우리나라 치과위생사의 커뮤니케이션 기술의 전문적인 발전과 연구에 활용되어 궁극적으로 환자 구강건강 증진 및 병원 경영에 도움을 줄 수 있을 것으로 생각된다.
