Late-life experiences such as protracted and indisposing medical disorders can negatively impact older adults' psychological and mental health, making them vulnerable to depression. Majority of the assessment tools for depression were developed for use in western countries. There is therefore the need for availability of culture- and environment-specific tools for assessment of depression in low-and-middle-income countries. This study was designed to cross-culturally adapt and validate the Geriatric Depression Scale-15 (GDS-15) into Igbo language and culture.
The English version of the GDS-15 was translated into Igbo language; synthesized, back-translated, and underwent expert panel review, pretesting and cognitive debriefing interview, according to the American Academy of Orthopedic Surgeons' guidelines. The Igbo version of the GDS-15 was tested for concurrent and structural validities, and internal consistency among consecutively recruited 140 consenting older adults (62.9% females) in Enugu North Senatorial District at 0.05 level of significance.
The English version of the GDS-15 was successfully cross-culturally adapted to Igbo with all the 15 items still retained on the Igbo version of the GDS-15. The Igbo version of the GDS-15 exhibited the same structure as the English version, and displayed a Cronbach's alpha value of 0.53 with no significant ceiling (0%) and floor (0%) effects. The correlation between the participants' total scores on the Igbo and the English versions of the GDS-15 (ρ = 0.86) was adequate. There was no significant difference between corresponding scores in the English and Igbo versions of the GDS-15 (p = 0.89).
The Igbo version of the GDS-15 is a valid and culturally specific instrument, and can be used for assessing depression among Igbo older adults in Nigeria.
晚年的经历，如长期的、不适的医疗疾病，会对老年人的心理和精神健康产生负面影响，使他们容易抑郁。大多数评估抑郁症的工具都是为西方国家开发的。因此，需要有针对中低收入国家的文化和环境特定的评估抑郁症的工具。本研究旨在将老年抑郁量表-15（GDS-15）跨文化地改编并适用于伊博语和伊博文化。
根据美国矫形外科医师学会的指南，将 GDS-15 的英文版本翻译成伊博语；综合、回译，并经过专家小组审查、预测试和认知性访谈。在恩古诺北参议员区连续招募 140 名同意的老年人（62.9%为女性），在 0.05 的显著性水平上，用伊博语版 GDS-15 测试其同时和结构有效性，以及内部一致性。
GDS-15 的英文版本成功地跨文化地改编为伊博语，伊博语版 GDS-15 仍保留了 15 个项目。伊博语版 GDS-15 与英文版具有相同的结构，Cronbach's alpha 值为 0.53，没有显著的上限（0%）和下限（0%）效应。参与者在伊博语和英语版 GDS-15 上的总分之间的相关性（ρ=0.86）是足够的。伊博语和英语版 GDS-15 的对应分数之间没有显著差异（p=0.89）。
伊博语版 GDS-15 是一种有效的、具有文化特异性的工具，可用于评估尼日利亚伊博族老年人的抑郁情况。
