level of agreement between self-rated and clinician-rated instruments when measuring major depressive disorder in the Thai elderly: a 1-year assessment as part of the ThAIsAD study

Purpose Whether self-reporting and clinician-rated depression scales correlate well with one another when applied to older adults has not been well studied, particularly among Asian samples. This study aimed to compare the level of agreement among measurements used in assessing major depressive disorder (MDD) among the Thai elderly and the factors associated with the differences found. Patients and methods This was a prospective, follow-up study of elderly patients diagnosed with MDD and receiving treatment in Thailand. The Mini International Neuropsychiatric Inventory (MINI), 17-item Hamilton Depression Rating Scale (HAMD-17), 30-item Geriatric Depression Scale (GDS-30), 32-item Inventory of Interpersonal Problems scale, Revised Experience of Close Relationships scale, ten-item Perceived Stress Scale (PSS-10), and Multidimensional Scale of Perceived Social Support were used. Follow-up assessments were conducted after 3, 6, 9, and 12 months. Results Among the 74 patients, the mean age was 68±6.02 years, and 86% had MDD. Regarding the level of agreement found between GDS-30 and MINI, Kappa ranged between 0.17 and 0.55, while for Gwet’s AC1 the range was 0.49 to 0.91. The level of agreement was found to be lowest at baseline, and increased during follow-up visits. The correlation between HAMD-17 and GDS-30 scores was 0.17 (P=0.16) at baseline, then 0.36 to 0.41 in later visits (P<0.01). The PSS-10 score was found to be positively correlated with GDS-30 at baseline, and predicted the level of disagreement found between the clinicians and patients when reporting on MDD. Conclusion The level of agreement between the GDS, MINI, and HAMD was found to be different at baseline when compared to later assessments. Patients who produced a low GDS score were given a high rating by the clinicians. An additional self-reporting tool such as the PSS-10 could, therefore, be used in such under-reporting circumstances.

Baseline characteristics of depressive disorders in Thai outpatients: findings from the Thai Study of Affective Disorders

Background The Thai Study of Affective Disorders was a tertiary hospital-based cohort study developed to identify treatment outcomes among depressed patients and the variables involved. In this study, we examined the baseline characteristics of these depressed patients. Methods Patients were investigated at eleven psychiatric outpatient clinics at tertiary hospitals for the presence of unipolar depressive disorders, as diagnosed by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The severity of any depression found was measured using the Clinical Global Impression and 17-item Hamilton Depression Rating Scale (HAMD) clinician-rated tools, with the Thai Depression Inventory (a self-rated instrument) administered alongside them. Sociodemographic and psychosocial variables were collected, and quality of life was also captured using the health-related quality of life (SF-36v2), EuroQoL (EQ-5D), and visual analog scale (EQ VAS) tools. Results A total of 371 outpatients suffering new or recurrent episodes were recruited. The mean age of the group was 45.7±15.9 (range 18–83) years, and 75% of the group was female. In terms of diagnosis, 88% had major depressive disorder, 12% had dysthymic disorder, and 50% had a combination of both major depressive disorder and dysthymic disorder. The mean (standard deviation) scores for the HAMD, Clinical Global Impression, and Thai Depression Inventory were 24.2±6.4, 4.47±1.1, and 51.51±0.2, respectively. Sixty-two percent had suicidal tendencies, while 11% had a family history of depression. Of the major depressive disorder cases, 61% had experienced a first episode. The SF-36v2 component scores ranged from 25 to 56, while the mean (standard deviation) of the EQ-5D was 0.50±0.22 and that of the EQ VAS was 53.79±21.3. Conclusion This study provides an overview of the sociodemographic and psychosocial characteristics of patients with new or recurrent episodes of unipolar depressive disorders.

Universality of interpersonal psychotherapy (IPT) problem areas in Thai depressed patients

BackgroundMany studies have shown the efficacy of interpersonal psychotherapy (IPT) on depression; however, there are limited studies concerning the universality of the IPT problem areas in different countries. This study identifies whether the interpersonal problem areas defined in the IPT manual are endorsed by Thai depressed patients.MethodsThe Thai Hamilton Rating Scale for Depression (Thai HRSD) and Thai Interpersonal Questionnaire were used to assess 90 depressed and 90 non-depressed subjects in King Chulalongkorn Memorial Hospital, during July 2007 - January 2008. The association between interpersonal problem areas/sociodemographic variables and depressive disorder were analyzed by chi-square test. A multivariable analysis was performed by using logistic regression to identify the remaining factors associated with depressive disorder.ResultsMost of the subjects were young to middle-aged females living in Bangkok and the Central Provinces. All four interpersonal problem areas (grief, interpersonal role disputes, role transitions, and interpersonal deficits) were increased in the depressed subjects as compared to the non-depressed subjects, as were the sociodemographic variables (low education, unemployment, low income, and having a physical illness). Logistic regression showed that all interpersonal problem areas still remained problems associated with depression (grief: adjusted OR = 6.01, 95%CI = 1.93 - 18.69, p < 0.01; interpersonal role disputes: adjusted OR = 6.01, 95%CI = 2.18 - 16.52, p < 0.01; role transitions: adjusted OR = 26.30, 95%CI = 7.84 - 88.25, p < 0.01; and interpersonal deficits: adjusted OR = 2.92, 95%CI = 1.12 - 7.60, p < 0.05).ConclusionAll four interpersonal problem areas were applicable to Thai depressed patients.

P02-350 - Universality of interpersonal psychotherapy (IPT) problem areas in Thai depressed patients

Objectives Many studies showed the efficacy of interpersonal psychotherapy (IPT) on depression; however, there were limited studies concerning the universality of the IPT problem areas in different countries. This study identified whether the interpersonal triggers of depression defined in the manual were present in Thai depressed patients. Methods Thai Hamilton Rating Scale for Depression (Thai HRSD) and Thai Interpersonal Questionnaire were used to assess the 90 depressed and 90 non-depressed subjects in King Chulalongkorn Memorial Hospital, during July 2007 - January 2008. The association between interpersonal problem areas / sociodemographic variables and depressive disorder were analyzed by chi-square test. The logistic regression was performed to identify the predictors of depressive disorder. Results Most of subjects were young and middle-aged females, living in Bangkok. All four interpersonal problem areas (grief, interpersonal role disputes, role transitions, and interpersonal deficits) were increased in the depressed as compared to the non-depressed subjects as well as in sociodemographic variables (low education, unemployment, low income, and having a physical illness). Logistic regression showed that all interpersonal problem areas still remained the significant predictors of depression. (grief: adjusted OR = 6.01, 95%CI = 1.93 - 18.69, p Conclusions All four interpersonal problem areas are applicable to Thai depressed patients.
