Psychometric Properties of Korean Version of Drug Attitude Inventory(KDAI-10) / 대한정신약물학회지

OBJECTIVE: The aim of this study was to test the psychometric properties of Korean version of 10 items of Drug Attitude Inventory (KDAI-10). METHODS: A total of 157 stabilized schizophrenic patients were entered into the study after completion of screening tests. They completed the KDAI-10. And then they were interviewed with various scales such as Subjective Response Scale (SRS), Positive and Negative Syndrome Scale (PANSS), Extrapyramidal Side Effects Rating Scale (ESRS), and Global Assessment of Functioning (GAF). Correlations of KDAI-10 with these scales were tested. RESULTS: The Cronbach's alpha used to measure the internal consistency of the scale, was high (0.83). Principal component analysis with varimax rotation produced 2 factors, which explained 50.37% of the total variances. The First factor including 6 items was the positive subjective feelings and the second factor including 4 items was the negative subjective feelings, which were identical to the original authors'. Individual item correlations with total scores were all statistically significant (r=0.48-0.72, p<.001). And correlations of KDAI-10 with SRS, PANSS, ESRS and GAF showed that they were significantly correlated. CONCLUSION: Although the results were not quite satisfactory, KDAI-10 was demonstrated to have good reliability and construct validity.

Subjective Response to Antipsychotics in Acute Manic Patients / 대한정신약물학회지

OBJECTIVE: It is well-known that antipsychotics are widely used in the treatment of bipolar disorder. So, the aim of this study was to examine the subjective response to antipsychotics in acute manic patients. METHODS: Data were gathered through the study for feasibility testing of Korean Medication Algorithm for Bipolar Disorder (KAMP-BP), which 17 nationwide clinical centers were entered into the study. A total 126 bipolar patients were enrolled and then 92 were treated according to the treatment algorithm. The data of 58 patients were completely recorded from baseline to 2 weeks of treatment and were entered into analysis. Drug Attitude Inventory-10 (DAI-10) was used for evaluating patient's subjective response to antipsychotics and patients were grouped as subjective non-dysphoric and dysphoric as the total score of DAI-10. For assessing the clinical status, Young Mania Rating Scale (YMRS), Clinical Global Impression- Severity scale (CGI-S), Hamilton Rating Scale for Depression (HAM-D), Global Assessment of Functioning (GAF) and Liverpool University Neuroleptic Side-Effect Rating Scale (LUNSERS) were used. RESULTS: Dysphoric group was younger and has more females in sex distribution than non-dysphoric group. YMRS and CGI-S were severer in dysphoric group. The prescription patterns were not different between two groups: Combinations of mood stabilizers and antipsychotics were administered to all patients and atypical antipsychotics were prescribed over 90% of the patients. At 2 weeks of treatment, more patients were turned into remission in non-dysphoric group. Dysphoric patients showed more changes of positive subjective response in DAI-10 from baseline and more patients turned toward the non-dysphoric group. CONCLUSION: Although the subjective response to antipsychotics using DAI-10 was not typically characterized in acute manic patients, it seems that atypical antipsychotics may have a role in determining the subjective feelings of the acute bipolar manic patients.
