Abstract

Infection control is now recognized as an important quality indicator in dental health service setting. The purpose of this study was to develop and validate Dental Hygienist's Infection Control Practice Scale for quality management of dental health service in Korea. The data of 254 dental hygienists was subjected to exploratory factor analysis using SPSS 16.0 and confirmatory factor analysis using AMOS 16.0. The total items of preliminary scale were 21 items and 5 subscale. Principal component analysis was completed with Varimax rotation. The results show a change in factor structure from 5 factor solution to 4 factor solution. The confirmatory factor analysis confirmed the four subscales(Immunization and periodic tests, Clinical procedure, Handwashing, Personal protection) which have a total of 12 items. After the item deleted because factor loading was low, measured model was tested. The results of the measurement model indicated fit indices: $x^2$= 79.593(df = 38, 0 = 0.000), RMR = 0.045, GFI = 0.940, CFI = 0.904, AGFI = 0.896, NFI = 0.837, TLI = 0.861, RMSEA = 0.67. The squared correlation between four constructs were less than the average variance extracted(AVE) of four constructs. Multiple regression analysis was completed. Dependent variable was the perceived infection control practice by dental hygienist. Independent variables were four summated subscales(R = 0.552, $R^2$= 0.304, Adjusted $R^2$= 0.431, F = 25.813, p = 0.000). Unstandardized coefficients of three independent variables were statistically significant.

치과위생사의 감염관리 실천도를 측정하는 척도를 개발하고 타당화하기 위해 254명의 치과위생사를 대상으로 설문조사를 실시하였다. 예비척도는 리커트 4점 척도로서 21개의 문항으로 구성되었으며, 신뢰도 분석, 탐색요인분석, 확인요인분석을 통해 척도의 차원과 항목을 축소하고 신뢰도와 타당도를 검증하였다. 1. 탐색요인분석과 신뢰도 분석을 통해 4개 요인과 12개의 항목으로 척도를 수정하였다. 수정된 척도의 요인은 '예방접종 및 정기검진'(2항목), '기구 소독 및 멸균'(3항목), '손위생 관리'(4항목), '개인 보호'(3항목)가 추출되었으며, 전체분산 중 58.296%를 설명하고 있다. 예비척도 중 '환경 관리' 요인이 제외되었다. 2. 확인요인분석을 통해 한 문항을 제외하였다. 최종적인 측정모형은 4개 요인과 11개 항목으로 구성되었으며, 모형의 적합도는 $x^2$= 79.593(df = 38, 0 = 0.000), RMR= 0.045, GFI = 0.940, CFI = 0.904, AGFI = 0.896, NFI = 0.837, TLI = 0.861, RMSEA = 0.67로 나타나 대체로 기준을 충족하였다. 모든 측정변수의 요인부하량은 유의하였으나(p < 0.001), 세 변수만이 0.7 이상으로 나타났다. 평균분산추출값과 구성개념신뢰도는 대체로 기준을 충족하지 못하였으나, 모든 요인의 평균분산추출값은 각 요인간 상관관계제곱값 보다 크게 나타났다. 3. 요인분석을 통해 추출한 네 개의 요인이 치과위생사의 '감염관리 실천률 인식'에 미치는 영향을 알아보기 위해 네 요인을 독립변수로 선정하고 실천률 인식을 종속변수로 선정하여 회귀분석을 실시하였다. $R^2$는 0.304, 수정된 $R^2$은 0.431, F = 25.813, p = 0.000이며, '손위생 관리'를 제외한 세 변수의 회귀계수는 통계적으로 유의하게 나타났다.
