Abstract

Objective: The Geriatric Depression Scale (GDS) is an evaluation tool to diagnose older adult's depression. This questionnaire was defined by Yesavage and Brink in 1982; it was designed expressly for the older person and defines his/her degree of satisfaction, quality of life, and feelings. The objective of this study is to evaluate the psychometric properties of the Italian translation of the Geriatric Depression Scale (GDS-IT).

Methods: The Italian version of the Geriatric Depression Scale was administered to 119 people (79 people with a depression diagnosis and 40 healthy ones). We examined the following psychometric characteristics: internal consistency reliability, test-retest reliability, concurrent validity, and construct validity (factor structure).

Results: Cronbach's Alpha for the GDS-IT administered to the depressed sample was 0.84. Test-retest reliability was 0.91 and the concurrent validity was 0.83. The factorial analysis showed a structure of 5 factors, and the scale cut-off is between 10 and 11.

Conclusion: The GDS-IT proved to be a reliable and valid questionnaire for the evaluation of depression in an Italian population. In the present study, the GDS-IT showed good psychometric properties. Health professionals now have an assessment tool for the evaluation of depression symptoms in the Italian population.

意大利版老年抑郁量表的心理测量特征评价。

目的:应用老年抑郁量表(GDS)对老年人抑郁症进行诊断。该问卷由Yesavage和Brink于1982年定义;它是专门为老年人设计的，并定义了他/她的满意度、生活质量和感受。本研究的目的是评估老年抑郁量表(GDS-IT)意大利语译本的心理测量特性。方法:采用意大利版老年抑郁量表对119人进行调查，其中抑郁症诊断者79人，健康者40人。我们检验了以下心理测量特征:内部一致性信度、重测信度、并发效度和构念效度(因子结构)。结果:抑郁症患者GDS-IT的Cronbach’s Alpha值为0.84。重测信度为0.91，并发效度为0.83。析因分析呈5个因子结构，分界点在10 ~ 11之间。结论:GDS-IT是一份可靠、有效的意大利人群抑郁评估问卷。在本研究中，GDS-IT显示出良好的心理测量特性。卫生专业人员现在有了一种评估意大利人口抑郁症状的评估工具。
