This study aimed to evaluate the diagnostic validity of the Beck Depression Inventory (BDI) in the elderly and to suggest an optimal cut-off score in order to screen major depressive disorder. The BDI and an elderly health questionnaire were administered to 2729 subjects over the age of 60 chosen by stratified random sampling in a Ansan City, South Korea. The BDI and geriatric depression scale (GDS) were examined at about a two-year interval. A reliability and validity test, a factor analysis and an ROC curve analysis were performed. Eighty-four subject had depression and 2645 subjects were rated as normal. The BDI showed significant positive internal consistency and test-retest reliability. Convergent validity with GDS was significantly positive, and an exploratory factor analysis revealed four factors. The authors suggest a score of 16 as the optimal cut-off point for the BDI when screening for major depression. The results of this study showed that the Korean version of the BDI is appropriate for screening for depression and 16 is the optimal cut-off score for the Korean elderly. Screening of elderly depression with BDI in the community would be valuable when comparing with younger adults and with their former BDI data which were taken when they were young.

Dental health is an important determinant of nutritional status, but has not been investigated as a risk factor for dementia. This study aimed to investigate the association between number of teeth, use of dentures and recent-onset dementia. This was a cross-sectional analysis nested within a prospective study of community dwelling elderly residents in two areas of Kwangju, South Korea. In a study of 686 community residents aged 65 or over without dementia followed over 2.4 years, measures of dental health were compared between those with and without dementia at follow-up. Fewer teeth were significantly associated with dementia and Alzheimer's disease. This association was strongest in participants without dentures. Strong associations were found between fewer teeth and indices of poor nutrition in this group, but these did not account for the association with dementia. Having fewer teeth may be a marker of risk for dementia. This might be explained by specific nutritional deficits, or by other side effects of periodontal disease. Further prospective research is indicated.
Self-enhancing bias in personality, subjective happiness, and perception of life-events: a replication in a Korean aged sample

Interrelations among self-enhancing bias in personality, subjective happiness, and perception of life-events have been examined. Elderly people with higher subjective happiness, compared to those with lower happiness, were predicted to have higher self-enhancing bias in personality, and perceive negative life-events less negatively. One hundred and forty elderly Korean citizens were assessed as to their tendency to self-enhance and to perceive positive and negative life-events. A correlation of 0.26 was found between subjective happiness and self-enhancing bias. Contrary to our prediction, those with higher subjective happiness perceived positive life-events more positively than those with lower subjective happiness, whereas there was no difference between the two groups in the perception of negative life-events.
