Abstract

This study was to develop an instrument for multidimensional measurement of Korean scaling fear (KSF)-1.0 and analyze related factors. A sample of 720 subjects(scaling patients and community people) was studied in Daegu city from November in 2008 to March in 2009. Authors first conceptualized the KSF, item generation, item reduction, and questionnaire formatting were performed in the stage of the development. Item descriptive, missing%, item internal consistency, and item discriminant validity were analyzed in the item-level, also descriptive, floor and ceiling effect were analyzed in the scale-level. Cronbach's alpha, test-retest, inter-dimension correlations, and factor analysis were performed to evaluate the validity and reliability in the new instrument. Confirmative factor analysis was did to evaluate the fit of model. The results for item-level and scale-level were acceptable except item discriminant validity. The reliability for 0.92~0.96 of corelation coefficient range(Cronbach's alpha 0.96~0.98) was high in the test-retest, and there was no significant difference in paired t-test. Item internal consistency(range of pearson corelation coefficient 0.39~0.95) was also high. The result of explanatory factor analysis was the same as the intended dimension structure, also confirmatory factor analysis results revealed that the dimensional structure model were fined well in the evaluation of model fit($x^2$= 1245.66, df=146, p=0.0000; GFI=0.85; AGFI=0.80; RMSEA=0.10). Factors related to KSF by multiple regression were gender($\beta$=0.28, p=0.0004) and teeth brush method($\beta$=-0.15, p=0.0053) in scaling patients, also gender($\beta$=0.25, p=0.0002), educational level($\beta$=0.14, p=0.0155), teeth brush method($\beta$=-0.09, p=0.0229) and time of daily work out($\beta$=-0.10, p=0.0055) were significantly associated with KSF in no scaling group. In conclusion, The results of this study reveal that the new developed measurement scale was reliable and val id instrument for measuring the KSF in dental hygiene patients and community people. We recommend that further research should develop more the instrument for the Korean scaling fear.

본 연구는 한국의 문화와 실정에 맞는 한국형 스켈링공포에 관한 측정도구를 개발하기 위해 2008년 11월 연구 대상자 720명을 대상으로 개방형 질문을 통해 문항을 수집하였고( 1차 조사), 2008년 12월과 2009년 1월에 스켈링 환자 110명을 대상으로 사전조사를 실시하여 측정도구의 영역설정 및 문항선정을 통해 1차 도구를 개발하였으며 (2차 조사), 2009년 2~3월에 연구대상자 720명에게 설문조사하여 최종적으로 4개 영역과 19개 문항을 결정함으로서 최종적으로 측정도구를 개발하였다. 문항수준 분석결과에서 결측치는 0.003%로 기준의 20%보다 낮아 양호했고, 검사-재검사 신뢰도 검중에서 상관계수가 0.92 이상으로 높았으며, 짝비교 t-검증도 조사 전후 간에 유의한 차이가 없어 신뢰도가 높았다. 문항 내적일치도 역시 전체 영역 내 상관계수 범위가 0.39~0.95로 높았으며, 항목판별타당도는 영역 간 상관계수가 0.56이하로 유의하였다. 영역수준의 분석결과 3개 영역의 평균 범위는 2.06~2.33 이었고 예상치 못한 신체반응의 공포영역은 1.29 이었다. 각 영역의 바닥치와 천장치는 각각 4.3%와 6.8%로 기준의 20% 보다 낮아 적합했고, 요인분석에서 일부 영역의 요인이 단일요인으로 묶이는 것을 제외하연, 각 영역별 문항이 동일 요인으로 묶여졌으며, 확인적 요인분석 결과에서 전반적으로 모형 합치도가 높았다. 스켈링 경험유무별 스켈링공포의 종속변수에 유의하게 영향을 미치는 연수분석에서 스켈링 경험자는 성별과 칫솔방법이 유의성이 있었고, 비 경험자는 성별, 교육수준, 칫솔방법, 그리고 일주 당 운동량 등이 유의했다. 이상으로 본 연구는 스켈링공포에 관한 측정도구를 총 4개 영역 19개 문항을 개발하였다. 향후 개발된 도구는 여러 집단을 대상으로 재평가를 받아 일반화 되어야 할 것이며, 이들 환자들에게 적용함으로서 정기적인 스켈링을 통한 구강보건향상에 기여할 것으로 판단된다.
