Differential Item Functioning of Geriatric Depression Scale for Urban-rural Differences
摘要
Abstract
Objective To explore the differential item functioning ( DIF) of geriatric depression scale-5 ( GDS-5 ) for urban-rural differences.Methods From January to February in 2012, the data of 550 elderly people enrolled in a previous research of expectation on aging by GDS-5 were collected.DIF of GDS-5 for urban -rural differences was analyzed by χ2 test.There were five items:1."Are you basically satisfied with your current life"; 2."Do you often feel bored and weary";3."Do you often feel there is no hope for life"; 4."Do you often prefer to stay at home rather than go out"; 5."Do you often feel current life is pointless".Unidimensional test was conducted to analyze CFI, TLI, REMSEA and SRMR, and EASY-DIF software was employed to investigate the DIF of GDS-5 for urban-rural differences.Results Significant rural-urban differences existed in item 2 and item 3 ( P <0.05 ); no significant rural -urban differences existed in other items ( P >0.05 ) . Unidimensional test showed that CFI, TLI, REMSEA and SRMR all accorded with fit standard, which suggested that each item of GDS-5 was measuring the same concept characteristic and had good construct validity.EASY-DIF software analysis showed that item 2 and item 3 were significantly different in MH value ( P<0.05 ) and no significant difference of MH value existed among other items (P>0.05) .TheΔαMH of item 2 was 0.915 and that of item 3 was 1.279.Conclusion The third item of GDS-5 has moderate DIF for urban -rural differences.DIF for urban-rural differences should be considered in the future comparison of depression between urban and rural elders.关键词
