Abstract

OBJECTIVES
The aims of this study were to examine validity and reliability of the Korean version of the Social Function Questionnaire (SFQ) and evaluated social function with SFQ in patients with personality disorder.
METHODS
The SFQ was administered to 186 psychiatric patients (155 patients with personality disorder and 31 patients without personality disorder), and 22 healthy men were recruited to examine the test-retest reliability of SFQ. The severity of personality disorders was determined using the proposed the International Classification of Diseases (ICD)-11th revision (ICD-11) personality disorders. All participants completed the NEO-Five Factor Inventory, Beck Depression Inventory, and Spielberger State and Trait Anxiety Inventory to examine the convergent validity of SFQ.
RESULTS
The Korean version of the SFQ showed good internal consistency (Cronbach's alpha=0.811) and test-retest reliability (r=0.746). Patients with personality disorder had more social dysfunction than those without personality disorder. A graded increase in social dysfunction was observed with increasing severity of personality disorder. Social dysfunction showed a strong linear relationship with the 5 factor model.
CONCLUSION
The Korean version of the SFQ has good psychometric properties. The results of our study support the severity classification of personality disorder integrated to upcoming ICD-11.
