Abstract

Objective: This study evaluated the validity and reliability of the Persian GDS-15 as a screening tool for depression in older adults with Parkinson's disease (PD), given its high prevalence and diagnostic challenges in this population.

Methods: This study included 160 older adults aged 65 years and above with a confirmed diagnosis of PD and 80 age-matched healthy controls. Participants completed the GDS-15, the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D), and the Beck Depression Inventory-II (BDI-II). Data were analyzed using exploratory factor analysis (EFA), Confirmatory factor analysis (CFA), Cronbach's alpha, Intraclass Correlation Coefficient (ICC) (Test-retest reliability), and Pearson correlation coefficient. Additionally, receiver operating characteristic (ROC) curve analysis was performed to determine the optimal diagnostic cutoff score.

Results: Exploratory factor analysis revealed a three-factor structure for the Persian GDS-15, demonstrating excellent reliability (α = 0.94; ICC = 0.92). Strong convergent validity was evidenced by significant correlations with HADS-D and BDI-II (both p < 0.001). ROC analysis established an optimal cutoff of ≤5, showing outstanding diagnostic accuracy (sensitivity = 98.7%, specificity = 84.7%) for depression detection in PD.

Conclusion: The Persian version of the GDS-15 is a reliable and valid instrument for assessing depression in older adults with PD and can be utilized in both clinical and research settings.

波斯语版老年抑郁量表-15在老年帕金森病患者中的效度和信度

目的：考虑到老年帕金森病（PD）的高患病率和诊断挑战，本研究评估了波斯GDS-15作为老年帕金森病（PD）抑郁症筛查工具的有效性和可靠性。方法：本研究包括160名65岁及以上确诊PD的老年人和80名年龄匹配的健康对照。参与者完成了GDS-15、医院焦虑与抑郁量表（HADS-D）的抑郁子量表和贝克抑郁量表- ii （BDI-II）。采用探索性因子分析（EFA）、验证性因子分析（CFA）、Cronbach’s alpha、类内相关系数（ICC）（重测信度）和Pearson相关系数对数据进行分析。此外，进行受试者工作特征（ROC）曲线分析以确定最佳诊断截止评分。结果：探索性因子分析显示波斯GDS-15具有三因子结构，具有良好的信度(α = 0.94；ICC = 0.92)。结论：波斯语版GDS-15是评估老年PD患者抑郁的一种可靠有效的工具，可用于临床和研究。

期刊介绍： pplied Neuropsychology-Adult publishes clinical neuropsychological articles concerning assessment, brain functioning and neuroimaging, neuropsychological treatment, and rehabilitation in adults. Full-length articles and brief communications are included. Case studies of adult patients carefully assessing the nature, course, or treatment of clinical neuropsychological dysfunctions in the context of scientific literature, are suitable. Review manuscripts addressing critical issues are encouraged. Preference is given to papers of clinical relevance to others in the field. All submitted manuscripts are subject to initial appraisal by the Editor-in-Chief, and, if found suitable for further considerations are peer reviewed by independent, anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
