Abstract

Objectives: Sub-threshold cases of depression and anxiety disorders in older adults are often undetected and undertreated. The 7-item Duke Anxiety-Depression Scale (DUKE-AD) assesses mental distress; this study evaluated the psychometric validity and cross-cultural applicability of its Persian version (DUKE-AD-PERSIAN).

Methods: A cross-sectional study among 500 older adults assessed for content and face validity as measured by 20 experts, and estimated content validity ratio (CVR) and item-level content validity index (I-CVI). Exploratory and Confirmatory Factor Analyses (EFA, CFA) examined the factor structure.

Results: Participants had a mean age of 70.62 ± 7.42 years and mean anxiety-depression score of 25.05 ± 22.39. The implemented EFA and CFA's outputs (CMIN = 29.933, DF = 11, pvalue = 0.002, CMIN/DF = 2.721, RMSEA = 0.05 (95% CI: 0.034, 0.084), PNFI = 0.511, PCFI = 0.515, TLI = 0.969, IFI = 0/984, CFI = 0.984) supported unidimensionality of the scale. The estimated reliability and stability coefficients (Cronbach's α = 0.98, ICC = 0.97) were acceptable.

Conclusions: Findings supported the reliability and validity of the Persian DUKE-AD as a brief self-report measure for assessing anxiety and depression in older adults.

Clinical implications: The Persian DUKE-AD enables efficient screening of anxiety and depression symptoms among older adults, facilitating early intervention in primary care and community health settings.

杜克焦虑抑郁量表（Duke - ad）在波斯语老年人中的心理测量验证和跨文化适应。

目的：老年人抑郁和焦虑障碍的亚阈值病例往往未被发现和治疗不足。由7个条目组成的杜克焦虑抑郁量表（Duke Anxiety-Depression Scale, Duke - ad）评估精神压力；本研究评估了其波斯语版本（DUKE-AD-PERSIAN）的心理测量效度和跨文化适用性。方法：采用横断面研究方法，对500名老年人进行内容效度和面部效度评估，由20名专家测量，并估计内容效度比（CVR）和项目级内容效度指数（I-CVI）。探索性和验证性因子分析（EFA， CFA）检验了因子结构。结果：参与者平均年龄为70.62±7.42岁，平均焦虑抑郁评分为25.05±22.39。实施的EFA和CFA的输出（CMIN = 29.933, DF = 11, pvalue = 0.002, CMIN/DF = 2.721, RMSEA = 0.05 (95% CI: 0.034, 0.084), PNFI = 0.511, PCFI = 0.515, TLI = 0.969, IFI = 0/984, CFI = 0.984）支持量表的单维性。估计的信度和稳定性系数（Cronbach's α = 0.98, ICC = 0.97）均可接受。结论：研究结果支持波斯DUKE-AD作为评估老年人焦虑和抑郁的简短自我报告测量的可靠性和有效性。临床意义：波斯DUKE-AD能够有效筛查老年人的焦虑和抑郁症状，促进初级保健和社区卫生机构的早期干预。
