PURPOSE
The purpose of this study was to compare depression, somatoform disorders, and quality of life among older adults.
METHODS
Samples of 280 community-dwelling Korean older adults were included. The age range of the participants was 60 to 90 years (average 72.6+/-6.4). The participants were assigned to one of two groups based on reported scores on the Pittsburgh Sleep Quality Index from September 2006 to March 2007. The two groups were designated as "poor sleepers"and "good sleepers". A T-test was used to compare depression, somatoform disorders and quality of life between the two groups.
RESULTS
Forty-six percent of participants reported scores that indicated they were poor sleepers. Poor sleepers reported significantly higher depression scores (p<.001), higher somatoform disorders scores (p<.001), lower for each SF-36 quality of life dimension, and lower mental and physical health summary scores (p<.001) than the reported scores of those participants who were classified as good sleepers.
CONCLUSION
Older adults with poor sleep patterns are more likely to report higher depression, more somatoform disorders and a lower quality of life. Additional research is needed to identify the appropriate nursing interventions aimed at improving sleep quality, depression symptoms, somatoform disorders and the quality of life.

PURPOSE
The objectives of this study were to examine the difference between scores assigned by dementia patients and their caregivers to the patients' anxiety, depression, and quality of life.
METHODS
After obtaining Institutional Review Board(IRB) approval, face-to-face interview with the patients and their caregivers respectively was conducted by trained graduate-level nursing students from December 2007 to February 2008. Patients' anxiety, depression, and quality of life were measured by patients and their caregivers. The data obtained were analyzed using the SPSS/WIN 14.0 program, which was used for frequency, percentage, mean , standard deviation, t-test, and Pearson's correlation.
RESULTS
Significant relationships were reported between the depression rated by patients and that rated by their caregivers(r = .37, p = .019). In addition, there was no difference between the quality of life rated by patients and that rated by their caregivers(t = -7.11, p = .479). However, there was no significant relationship between the anxiety rated by patients and that rated by their caregivers(r = .21, p = .195).
CONCLUSION
There were no differences on level of depression and quality of life of dementia patients measured by dementia patients and caregivers, However, dementia patients' anxiety level has discrepancy between them.
