A Validation Study of Korean Version of Personality Beliefs Questionnaire-Short Form (PBQ-SF) / 신경정신의학

OBJECTIVES: The Personality Belief Questionnaire-Short Form (PBQ-SF) is a self-report instrument for assessment of dysfunctional beliefs based on Beck's cognitive formulations of personality disorders. The aims of this study was to examine the reliability and validity of the Korean version of PBQ-SF in clinical samples. METHODS: The Korean version of PBQ-SF was examined in 115 participants (50 patients with personality disorder and 65 patients without personality disorder). All participants were assessed for personality disorder using the semi-structured clinical interview of the Personality Assessment Schedule. The construction validity was examined by correlation with Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory, and Neuroticism-Extraversion-Openness Five-Factor Inventory neuroticism scales. Twenty four randomly sampled patients were examined for the test-retest reliability. RESULTS: The Korean version of PBQ-SF showed good internal consistency [Cronbach's alpha=0.73 (schizoid)-0.92 (paranoid)] and test-retest reliability [r=0.74 (narcissistic)-0.92 (paranoid)]. The PBQ-SF was correlated with depression, anxiety, and neuroticism. The overall subscales of PBQ-SF were correlated with Diagnostic and Statistical Manual of Mental Disorders based diagnosis of personality disorders. CONCLUSION: Consistent with previous findings using the Korean full version of PBQ as well as the English version of PBQ-SF, our results support that the Korean version of PBQ-SF is a reliable and valid instrument for assessment of dysfunctional beliefs associated with personality pathology.

Social Function in Patients with Personality Disorder Diagnosed by Single Dimensional Severity Using Korean Version of Social Functioning Questionnaire / 신경정신의학

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.

Diagnostic Efficiency of Personality Disorder Screening Tool ; The Korean Version of Self-Report Standardized Assessment of Personality-Abbreviated Scale : Preliminary Validation Study / 신경정신의학

OBJECTIVES: The aims of this study were to evaluate acceptability and usefulness of the Korean version of Self-report Standardized Assessment of Personality-Abbreviated Scale (SAPAS-SR) as an instrument for screening patients with a personality disorder. METHODS: The Korean version of the SAPAS-SR was administered to a non-random sample of 186 psychiatric patients (155 patients with a personality disorder and 31 patients with no personality disorder). The International Classification of Diseases 10th version Personality Assessment Schedule was used as a gold standard in diagnosis of personality disorder. Receiver-operant-characteristics and validity indicators were determined. In addition, the SAPAS-SR was administered to 22 healthy men to examine the test-retest reliability. RESULTS: The area under the curve for the SAPAS-SR was 0.69 (95% confidence interval 0.59-0.79). The SAPAS-SR score of 4 or more correctly classified 67.2% of patients with a personality disorder. Sensitivity (0.67) and specificity (0.68) were slightly lower compared with the original English version. CONCLUSION: This study provides preliminary evidence of the usefulness of the Korean version of the SAPAS-SR as a self-administered instrument for screening personality disorders in the clinical population.

MMPI Profile in Patients with Chronic Low Back Pain / 대한정형외과학회잡지

PURPOSE: The causative pathology of chronic low back pain cannot be defined in many patients. To evaluate the relations between psychoneurotic status and chronic low back pain, the authors surveyed Minnesota Multiphasic Personal Inventory (MMPI) in the patients with chronic low back pain. MATERIALS AND METHODS: From July 1997 to December 1998, questionaire including MMPI were given to the patients who visited our Department for chronic (>6 weeks) low back pain. 50 patients (33 male, 17 female) completed MMPI. The mean age was 33.4 years (range 17-55) . MMPI scores were evaluated in two ways for each individual, mean scores of each clinical scale and two code method. Then mean scores were compared according to sex, radiating pain, radiologic abnormalities. RESULTS: In total 50 patients, three scales showed mean score over 55. Those were Hs:59.1 +/- 10.3, D:55.4 +/- 11.2 and Hy: 59.0 +/- 10.8. No significant differences were observed between the groups divided according to the sex, radiating pain, radiologic abnormalities. The two code method revealed that at least one of the neurotic triad (Hy, Hs, D) ranked within the highest two in 46 (92%) patients. CONCLUSION: It seemed that large proportion of patients with chronic low back pain had psychological tendency to hypochondriasis and/or depression and/or hysteria. MMPI seemed to be one of the useful methods in evaluation of psychogenic factors in chronic low back pain patients without definite organic pathology.
