The purpose of this study is to examine the reliability and validity of a Geriatric Depression Scale Short Form Korea version(GDSSF-K), GDSSF-K, BDI and SDS were administered to 176 depressed elderly and 84 nondepressed elderly. The GDSSF-K was
highly
correlated with the BDI(r=0.50) and the SDS(r=0.50). The median correlation between items of the GDSSF-K and corrected-item scores was 0.65, and the mean interitem correlation from the GDSSF-K was 0.35. The value of Cronbach's a coefficient was
0.88.
The split-half reliability coefficient and test-retest correlation coefficient were 0.85 and 0.90 respectively. The results of testing the validity of the GDSSF-K examined by the t-test provided evidence for the validity of the scale(t=-7.07, d.
f.=224.87, P<0.001). The results of examining the sensitivity and the specificity of GDSS-K were revealed that cut-off score of 5 yielded a 42.3% sensitivity rate and a 88.7% specificity rate. To identify the factor structure of GDSSF-K, we
performed
the factor analysis. A s result, we found 2 factors in GDSSF-K, which were labeled as anti-vitality factor(factor 1) and depression factor(factor 2). The total percents of variance of 3 factors were 57.6%. The suggestions of GDSSF-K and the cross
cultural consideratons were discussed.
