A Preliminary Study on Development Korean Version of the Modified Erickson Scale of Communication Attitudes(S-24)

Erickson의 의사소통 태도 척도(S-24)의 국내 적용을 위한 타당도 및 신뢰도 연구

For the exact assessment and diagnosis of stuttering, not only speech disfluency but also the attitude of stuttering has to be considered. However, clinical researches and studies about stuttering have tend to center around disfluency. Relatively little attention was paid to the communication attitude of stuttering. In this paper, we will attempt to investigate that the Modified Erickson Scale of Communication Attitudes(S-24) is available in Korean stutterer. The S-24 was administrated to 27 adults with stuttering and 27 normal adults. Based on the item analysis of S-24, 4 items which have the low item discrimination coefficient and are little difference between stutterer group and normal group were excepted from the scale. To test validity of the reconstructed communication attitude scale, we estimated a internal consistency and carried out correlation analyses and discrimination analyses. We found that the reconstructed scale had a high internal consistency(a = .8701), was consisted six components(explanatory power = 66.59% of total variation), correlated with the PSI at .439 and with the SESAS at -.527, and correctly classified between stutterers and normal adults at 92.6%. Consequently, the reconstructed communication attitude scale is a useful scale to assess stutterer's communication attitude in Korea.
