Abstract

OBJECTIVES
The present study was designed to assess the reliability and validity of Korean version of Family Questionnaire (FQ-K), a brief questionnaire measuring expressed emotion (EE).
METHODS
A sample of 84 first-order relatives of schizophrenics completed the FQ-K and the data were analyzed for internal consistency and factor structure. Additionally non-random subset of participants (n=34) refilled FQ-K after two weeks for testretest reliability and naturalistic follow-up data of 36 were obtained for any re-hospitalization events to assess predictive validity.
RESULTS
Internal consistency of FQ-K was good (Cronbach's alpha=.819) and principal component factor analysis revealed the two-factor structure (criticism and emotional overinvolvement) identical to previously reported for the FQ. The FQ-K also showed reasonable test-retest reliability and excellent predictive validity was indicated in that outcome of re-hospitalization was superior for low expressed emotion patients at six-month naturalistic follow-up.
CONCLUSION
The Korean version of FQ proved to be a reliable and valid instrument measuring expressed emotion in relatives of Korean patients with schizophrenia.
