Abstract
The purpose of this study was to verify the reliability and validity of the Korean version of Family Communication Scale(in the FACES IV Package). The sample consisted of 460 couples who enrolled in the Family Cohort Research Project (PI: Young Sik Kim). The original questionnaire in the FACES IV Package, which was developed by Olson and Barnes(2008), was translated in Korean in accordance with Olson's Guidelines for Translating FACES IV Package, and analyzed by Pearson's correlation coefficients, paired t-test, Cronbach's $\alpha$, Guttman's split coefficients, simple regression, seemingly unrelated regression, and factor analysis. In order to test the concurrent validity, cohesion scores and adaptability scores of FACES III and CED-S scores were used. So as to understand the difference between individual data and coupled data, we analyzed the data of individual and couple, respectively. Cronbach's alphas are .92 and .93; Guttman's split coefficients are .90 and .92. Then, the data were analyzed by principle axis factoring and varimax rotation with the number of factors fixed to one. One factor explained 55.8% of total variance in the case of individual, and 60.8% of total variance in couple. Pearson's correlation coefficients are .64 and .67 between Family Communication and Family Cohesion; .34 and .37 between Family Communication and Family Adaptability; -.27 and -.30 between Family Communication and Depression. These results suggested that, in its Korean version, Olson and Barnes's Family Communication Scale is generally a reliable and valid instrument for measuring family communication among Korean couples.
