The reliability and validity of the Korean family function assessment tool

ABSTRACT

BACKGROUND: We developed Korean Family Function Assessment Tool(KFFAT). In order to confide in the results of the KFFAT, it was necessary to verify the psychometric properties(validity and reliability). METHODS: To evaluate the reliability of the KFFAT, internal consistency and scale-item correlation was carried out with 800 middle and high school students and their 800 parents. A three-week interval test-retest was also carried out with 50 high school students and their 50 parents. In addition, the KFFAT was compared to the family APGAR and the FACES III to evaluate the validity with 800 middle and high school students and their 800 parents. RESULTS: Cronbach alpha of each scale was 0.55-0.88 and overall scale-item correlation coefficient was believed to be appropriate. Pearson's correlation coefficient of test-retest was 0.49-0.79 in each scale. There is little correlation between the Family APGAR and the FACES III with the KFFAT. However, the KFFAT shows similar results in the function of family with the Family APGAR and the FACES III. CONCLUSION: From this reliability and validity test results, the Korean Family Function Assessment Tool(KFFAT) could be used as a assessment tool of Korean family function.
