Objectives: To assess the concurrent and the construct validity of the Euro-D in older Thai persons. Method: Eight local psychiatrists used the major depressive episode section of the Mini International Neuropsychiatric Interview to interview 150 consecutive psychiatric clinic attendees. A trained interviewer administered the Euro-D. We used receiver operating characteristic (ROC) analysis to assess the overall discriminability of the Euro-D scale and principal components factor analysis to assess its construct validity. Results: The area under the ROC curve for the Euro-D with respect to major depressive episode was 0.78 [95% confidence interval (CI) 0.70–0.90] indicating moderately good discriminability. At a cut-point of 5/6 the sensitivity for major depressive episodes is 84.3%, specificity 58.6%, and kappa 0.37 (95% CI 0.22–0.52) indicating fair concordance. However, at the 3/4 cut-point recommended from European studies there is high sensitivity (94%) but poor specificity (34%). The principal components analysis suggested four factors. The first two factors conformed to affective suffering (depression, suicidality and tearfulness) and motivation (interest, concentration and enjoyment). Sleep and appetite constituted a separate factor, whereas pessimism loaded on its own factor. Conclusion: Among Thai psychiatric clinic attendees Euro-D is moderately valid for major depression. A much higher cut-point may be required than that which is usually advocated. The Thai version also shares two common factors as reported from most of previous studies.

Objective: The Depression in Old Age Scale (DIA-S) is a new screening tool for assessing depression in the elderly. The primary aims of this study were to describe the validation of the Korean version of the DIA-S (K-DIA-S) and to compare its validity with that of other depression screening questionnaires used in elderly outpatients in medical settings. Methods: A total of 385 elderly outpatients completed the K-DIA-S and underwent the Mini International Neuropsychiatric Interview to diagnose depressive disorders. Other measures included the 15-item short form of the Geriatric Depression Scale (SGDS), the 9-item depression module of the Patient Health Questionnaire (PHQ-9), and the Montgomery-Asberg Depression Rating Scale (MADRS). Reliability and validity tests, an optimal cutoff point estimate, and receiver operating characteristic curve analysis were performed to investigate the diagnostic validity of the K-DIA-S. Areas under the curves (AUCs) for the K-DIA-S, SGDS, and PHQ-9 were compared statistically. Results: The K-DIA-S showed good internal consistency and strong correlations with the SGDS (r = 0.853), PHQ-9 (r = 0.739), and MADRS (r = 0.772). The cutoff point of the K-DIA-S that can be recommended for screening depressive symptoms was a score of 4. For "any depressive disorder", the AUC (standard error) for the K-DIA-S was 0.896 (0.015), which was significantly larger than that for the PHQ-9 (p = 0.033). Conclusion: The present findings suggest that the K-DIA-S has good psychometric properties and is a valid and reliable tool for assessing depressive symptoms in elderly populations and medically ill patients.
Development of the Thai Depression Inventory
JOURNAL-MEDICAL ASSOCIATION OF …, 1999
The Thai Depression Inventory was developed as a self-rating instrument for measuring the severity of depression. The items used were based on widely used Western scales and on common manifestations and idioms of distress among depressed Thai subjects. The scale was tested with 50 depressed patients using the Hamilton Rating Scale for Depression as an external standard. The internal reliability and concurrent validity were good (Cronbach alpha = 0.858; r = 0.72). The items of psychomotor retardation and loss of libido were poorly correlated with the total score. Factor analysis revealed five distinct factors which accounted for 59.8 per cent of the total variance. Anxiety-insomnia factor was the predominant factor. For major depressive patients, the Thai Depression Inventory total score is 35 or above. The Thai Depression Inventory is a culturally appropriate instrument for measuring the severity of depression with satisfactory reliability and validity.

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.
Geriatrics, 2021
The proportion of geriatric depression recorded in Vietnam was 66.9%. Depression in older people is a risk factor for problems related to dementia, poor quality of life, and suicide. To have a good Vietnamese questionnaire for assessing geriatric depression, we conducted the study to translate and cross-culturally adapt the Geriatric Depression Scale—long-form with 30 items (GDS-30). The study has two steps. Step 1 is a translation of the GDS-30 scale. We followed the guideline by Beaton et al., (2000 & 2007). Firstly, two translators (informed and uninformed) translated the questionnaires. Secondly, the translations were synthesized. Thirdly, back translation was performed by two translators fluent in both Vietnamese and English but completely unknown of the original version of the scale and did not have medical expertise. Finally, seven experts reached a consensus on the pre-final Vietnamese version (GDS-30). Step 2 is a field test of the questionnaires on people 60 years or older...
Differential item functioning of the Geriatric Depression Scale in an Asian population
Journal of Affective Disorders, 2008
Background: The Geriatric Depression Scale (GDS) is widely used for screening and assessment of major depressive disorder (MDD). Screening scales are often culture-specific and should be evaluated for item response bias (synonymously differential item functioning, DIF) before use in clinical practice and research in a different population. In this study, we examined DIF associated with age, gender, ethnicity and chronic illness in a heterogeneous Asian population in Singapore. Methods: The GDS-15 and Structured Clinical Interview for DSM-IV diagnosis of MDD were independently administered by interviewers on 4253 non-institutionalized community living elderly subjects aged 60 years and above who were users of social service agencies. Multiple Indicator Multiple Cause latent variable modelling was used to identify DIF. Results: We found evidence of significant DIF associated with age, gender, ethnicity and chronic illness for 8 items: dropped many activities and interests, afraid something bad is going to happen, prefer staying home to going out, more problems with memory than most, think it is (not) wonderful to be alive, feel pretty worthless, feel (not) full of energy, feel that situation is hopeless. Limitations: The smaller number of minority Indian and Malay subjects and the self-report of chronic medical illnesses. Conclusions: In a heterogeneous mix of respondents in Singapore, eight items of the GDS-15 showed DIF for age, gender, ethnicity and chronic illness. The awareness and identification of DIF in the GDS-15 provides a rational basis for its use in diverse population groups and guiding the derivation of abbreviated scales.
The aim of the present study was to examine the factor structure and psychometric properties of the 8-item short version of the Center for Epidemiologic Studies-Depression Scale (CES-D) in a large sample of European older adults. Data from The European Social Survey (ESS Round 6 Edition 1.1) provided the basis for this study (5,774 Males and 7,258 Females). Exploratory and confirmatory factor analyses provided support for a single factor structure. The results from multi-group confirmatory factor analyses revealed that the factor structure of the CES-D 8 is invariant across sexes, including invariance of item intercepts, item residuals, and item factor loadings. Moreover, the results provided support for the nomological validity of the scale. These results suggest that the shorter 8-item CES-D scale is a valid and reliable instrument of depression and extends the list of available instruments for screening depression among older adults.
Depression Research and Treatment
Background. The assessment to provide care and support to patients with major depressive disorder (MDD) currently focuses on the recovery from the disease, but it is still lacking in measuring and developing psychological well-being among Thai patients with MDD. Therefore, this research is aimed at studying the psychometric properties of the Thai version psychological well-being scale and study factors related to among patients with MDD. Materials and Methods. The Thai version psychological well-being scale, an 8-point Likert-type scale, was translated by our research team and used to examine psychometric properties as well as to identify the factors related to psychological well-being in a cross-sectional study among samples of 111 patients diagnosed with MDD from Princess Maha Chakri Sirindhorn Medical Center in Nakhon Nayok Province, Thailand. Results. Cronbach’s alpha for the Thai version psychological well-being scale was .91, unidimensionality was examined with exploratory fac...
