Abstract:

Purpose Cross - sectional study to validate a Spanish version of the 5 and 15 items Geriatric Depression Scale ( GDS 5 and 15 ) in a non - selected community dwelling older population , compared with the clinical diagnosis of depression ( using DSM - IV criteria ) as gold standard . Patients and method A total of 301 subjects randomly selected from the >64 years old population served by a public Primary Care Center in Madrid were included . Severe cognitive impairment ( MMSE < 20/30 ) , severe hearing impairment and denial to participate were exclusion criteria . A descriptive and a screening study were performed . Results The prevalence of depression in this population was 14 .6% . The 5 - item GDS had a sensitivity of 0 .864 ( 0 .762 - 0 .965 ) , specificity of 0 .856 ( 0 .813 - 0 .899 ) , PPV 0 .507 ( 0 .394 - 0 .62 ) , NPV 0 .973 ( 0 .952 - 0 .994 ) , and positive likelihood ratio 6 ( 4 .34 - 8 .26 ) . The 15 - item GDS had a sensitivity of 0 .818 ( 0 .704 - 0 .932 ) , specificity of 0 .977 ( 0 .958 - 0 .995 ) , PPV 0 .857 ( 0 .751 - 0 .963 ) , NPV 0 .969 ( 0 .948 - 0 .99 ) , and positive likelihood ratio 35 .03 ( 28 .76 - 40 .77 ) . Conclusions GDS - 5 may be useful screening test for depression in non selected elderly patients in primary care . It has better sensitivity than GDS - 15 and similar area under curve .
