| Annotation | The study population included all individuals who comprised the Bambuí, southeastern Brazil baseline cohort in 1997, and who answered the General Health Questionnaire (GHQ-12) and Geriatric Depression Scale (GDS-30) items in 2001, the fourth year of follow-up. The prevalence of depressive symptoms was determined for different cut-points and correction methods. The agreement between the scales was measured using the Kappa coefficient. 1,291 individuals (625 female, 22% aged 75+) took part in the 2001 follow-up, and 1,172 answered both scales. Median scores were 2.7 for the GHQ-12 and 11.7 for the GDS-30. To the authors' knowledge, this is the first study comparing the GHQ-12 and GDS-30. High prevalence was found of depressive symptoms in this cohort, especially with the GDS-30 scale. The agreement between the scales was only reasonable. These results indicate the importance and urgency of validating these scales and investigating the factors contributing to these results. (KJ/RH). |
