Objectives: The purpose of this study was to develop an instrument for Korean Scaling Fear (KSF)-1.1 in scaling patients.
Methods: 402 sample size for scaling patients was studied in Daegu city in July and August of 2011. Mean and standard deviation was calculated in 3 dimensions(FWS: fear while scaling, DDH: distrust on dental hygienist, FAS: fear after scaling).
Results: Age of 402 subjects was 36.5 years. In analyzing reliability for item-level, a range of correlation coefficient() on i tem-internal c onsistency(FWS, DDH, and FAS) w as 0 . 58∼0. 88(=0.90), 0.40∼ 0.71(=0. 82), a nd 0 . 54∼0. 63(=0.82), respectively. Floor(%) and ceiling(%) value on 3 dimensions were also 9.2% and 4.0%, 12.4% and 0.5%, and 17.7% and 1.2%, respectively, therefore, we found statistically high reliability for those(p<0.001). With explanatory factor analysis, this study could generate 3 dimensions(factor 1, eigenvalue 5.41, proportion 0.49; factor 2, eigenvalue 1.50, proportion 0.14; factor 3, eigenvalue 1.04, proportion 0.09) and 11 sub-scales. Also confirmatory factor analysis results showed that the KSF1.1 model was fitted very well in analysis of model fit(χ2=112.94, df=41, p=0.000; goodness of fit index=0.95; adjusted goodness of fit index=0.92; root mean square residual=0.057).
Conclusions: In conclusion, The findings of this study showed that developed reliable and valid instrument for measuring the KSF1.1 in the scaling patients.
