Research on development of the manual for self detection of depression in the Thai elderly.

The purposes of this study were to develop an effective manual for the early self detection of depression in the Thai elderly, to detect the comorbidity of depression (pattern of drug and alcohol abuse, suicidal idea) and to ascertain the quality of life. A quasi experimental field research methodology (Randomized Control Group Pretest-Posttest Design) was implemented. The sample consisted of 1,390 elderly people in 35 communities from 4 districts surrounding Siriraj Hospital-Bangkok Noi, Bangkok Yai, Taling Chan and Bang Phlat. These areas are the peripheral parts of Bangkok and most of them have extended families. The result showed that: 1. The internal consistency reliability of the nine criteria of the manual for the self detection of depression in the Thai elderly ranged from 0.84 to 0.94. The validity tested by epidemiological methods, disclosed that the sensitivity was 82.14 per cent and the specificity was 97.56 per cent. 2. There was a statistically significant difference in the incidence of depression between the study and the control group (p<0.000); self referred cases = 86.7 per cent and 9.8 per cent respectively. The study group was able to detect depression in 42 days, while the control group did so in 122 days. In addition, in the associated comorbidity, there were differences in the patterns of drug and alcohol abuse, suicidal ideas and quality of life after the experiment. These findings showed a decreasing pattern of self medication for depression, and suicidal ideas and an improvement in the quality of life in the study group.

Prevalence and incidence of depression in the Thai elderly.

The purposes of this study were to study the prevalence and incidence of depression in elderly Thais. A field survey study was implemented. The sample consisted of 1,713 elderly people in 35 communities from 4 districts surrounding Siriraj Hospital Bangkok Noi, Bangkok Yai, Taling Chun and Bang Plud. These areas are the peripheral part of Bangkok and most of them have extended family. The Thai Geriatric Depression Scale (TGDS) and the Thai Mini Mental State Examination (TMSE) were used as screening tests, for data collection. The prevalence of depression was 12.78 per cent, of which 8.23 per cent had only depressive symptomatology (male 5.43%, female 9.63%) while 4.55 per cent had both depression and cognitive impairment (male 2.8%, female 5.54%). The point incidence (one year) of depression was 7.27 (male 1.58%, female 5.68%). The major contributing factors in depression were financial, poor family relationships and physical illness. The prevention and management of these factors may bring about a better quality of life for the elderly in Thailand.
