title: Validation of the Tamil version of short form Geriatric Depression Scale-15.
abstract: BACKGROUND
  Local language screening instruments can be helpful in early assessment of depression in the elderly in the community and primary care population. This study describes the validation of a Tamil version of Geriatric Depression Scale (short form 15 [GDS-15] item) in a rural population.
  
  
  METHODS
  A Tamil version of GDS-15 was developed using standardized procedures. The questionnaire was applied in a sample of elderly (aged 60 years and above) from a village in South India. All the participants were also assessed for depression by a clinical interview by a psychiatrist.
  
  
  RESULTS
  A total of 242 participants were enrolled, 64.9% of them being females. The mean score on GDS-15 was 7.4 (±3.4), while the point prevalence of depression was 6.2% by clinical interview. The area under the receiver-operator curve was 0.659. The optimal cut-off for the GDS in this sample was found at 7/8 with sensitivity and specificity being 80% and 47.6%, respectively.
  
  
  CONCLUSIONS
  The Tamil version of GDS-15 can be a useful screening instrument for assessment of depression in the elderly population.
