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).
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).
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.
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.
老年抑郁量表（GDS）是一种用于诊断老年人抑郁症的评估工具。该问卷由耶萨维奇和布林克于1982年定义；它是专门为老年人设计的，用于界定其满意度、生活质量和感受。本研究的目的是评估老年抑郁量表意大利语版（GDS-IT）的心理测量特性。
对119人（79名被诊断为抑郁症的人和40名健康人）施测老年抑郁量表意大利语版。我们考察了以下心理测量特征：内部一致性信度、重测信度、同时效度和结构效度（因子结构）。
施测于抑郁样本的GDS-IT的克朗巴哈系数为0.84。重测信度为0.91，同时效度为0.83。因子分析显示有一个5因子结构，量表临界值在10至11之间。
GDS-IT被证明是评估意大利人群抑郁症的可靠且有效的问卷。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用于评估意大利人群抑郁症状的评估工具。
