Validity and reliability of Faces III ad a tool of middle school student's family function evaluation-When student himself only responses

ABSTRACT

BACKGROUND: FACES III is a useful instrument for the evaluation of family function. It was translated with evaluation of it's validity and reliability and used in many researches in Korea. But following studies for validity and realiability of FACES III didn't show consistent results. And for the evaluation of family function of middle school students, FACES III can be a useful tool. But it is important to reinvestigate the validity and reliability of FACES III to apply this instrument to them. METHODS: In 1997, self-report instrument FACES III questionnaires were distributed to all members of one boys' middle school students in Inchon. The 1150 questionnaires except incomplete questionnaires from 1249 students were analyzed. RESULTS: The Cronbach's alpha coefficients for internal consistency reliability were 0.71 for adaptability and 0.80 for cohesion. The Pearson's correlation coefficient between cohesion and adaptability for construct validity was 0.59. Correlations between total scores and each item scores were moderate to strong, correlations between items in subcategory were weak. In factor analysis, there were many items that were not compatible with factors according to concept of FACES III. CONCLUSION: The validity and reliability of FACES III can not be guaranteed when applied to the evaluaton of middle school students' family function.
