背景：在乌干达，抑郁症是一个主要的公共卫生问题，因为它具有直接的疾病负担，并且是其他普遍健康问题的危险因素和共病。对抑郁症测量结果进行心理测量评估对于公共卫生规划至关重要，以确保对抑郁症及相关结果进行适当的筛查、监测和治疗。我们在乌干达青少年和成人的大型人群队列中检查了患者健康问卷 9 (PHQ-9) 翻译成卢干达语和 Runyoro 的有效性和可靠性。方法：对乌干达瓦基索和霍伊马地区正在进行的开放队列 AMBSO 人口健康监测研究的数据进行了分析。对整个样本进行描述性统计，并按翻译语言进行分层。使用序数数据的验证性因素分析来评估每个翻译量表的结构有效性。使用 Cronbach's alpha、McDonald's omega 总和 omega 分层来评估每个翻译量表的内部一致性。 结果：与来自 Hoima 的 Runyoro 语子样本 (n=2297) 相比，来自 Wakiso 的卢干达语子样本 (n=672) 的参与者年龄更大（27 岁 vs 21 岁，p < 0.01），并且女性比例更大（62% vs. 55%，p < 0.01）。 Luganda 翻译的 PHQ-9 的样本平均值为 3.46 (SD = 3.26)，支持单因素结构 (RMSEA = 0.05，CFI = 0.96，TLI = 0.94)，并表现出令人满意的内部一致性 (Cronbach's alpha = 0.73，McDonald's omega 总计 = 0.76，McDonald's omega 分层 = 0.53)。 Runyoro 翻译的 PHQ-9 的可比样本平均值为 3.58 (SD=3.00)，也支持单因素结构 (RMSEA=0.08，CFI=0.92，TLI=0.90)，并表现出令人满意的内部一致性 (Cronbach's alpha=0.72，McDonald's omega 总计=0.76，McDonald's omega hierarchical=0.57)。结论：我们的初步结果研究结果表明，PHQ-9 的卢干达语和 Runyoro 翻译在我们的乌干达青少年和成人样本中具有令人满意的结构效度和内部一致性。未来的研究应该通过评估乌干达其他社区这些转化措施的额外心理测量特征来扩展这项有希望的工作。
BACKGROUND: In Uganda, depression is a major public health issue because of its direct disease burden and as a risk factor and co-morbidity for other pervasive health issues. Psychometric assessment of translated depression measures is critical to public health planning to ensure proper screening, surveillance, and treatment of depression and related outcomes. We examined aspects of the validity and reliability of the Patient Health Questionnaire-9 (PHQ-9) translated into Luganda and Runyoro in a large population-based cohort of Ugandan adolescents and adults.METHODS: Data from the ongoing open cohort AMBSO Population Health Surveillance study were analyzed from the Wakiso and Hoima districts in Uganda. Descriptive statistics were calculated for the overall sample and stratified by translated language. Construct validity was assessed for each translated scale using confirmatory factor analysis for ordinal data. The internal consistency of each translated scale was assessed using Cronbach's alpha, McDonald's omega total and omega hierarchical.RESULTS: Compared to the Runyoro-speaking subsample from Hoima (n=2297), participants in the Luganda-speaking subsample from Wakiso (n=672) were older (27 vs 21 years, p < 0.01) and a greater proportion were female (62% vs. 55%, p < 0.01). The Luganda-translated PHQ-9 had a sample mean of 3.46 (SD=3.26), supported a single-factor structure (RMSEA=0.05, CFI=0.96, TLI=0.94), and demonstrated satisfactory internal consistency (Cronbach's alpha=0.73, McDonald's omega total=0.76, McDonald's omega hierarchical=0.53). The Runyoro-translated PHQ-9 had a comparable sample mean of 3.58 (SD=3.00), also supported a one-factor structure (RMSEA=0.08, CFI=0.92, TLI=0.90), and demonstrated satisfactory internal consistency (Cronbach's alpha=0.72, McDonald's omega total=0.76, McDonald's omega hierarchical=0.57).CONCLUSIONS: Our preliminary findings indicate that the Luganda and Runyoro translations of the PHQ-9 had satisfactory construct validity and internal consistency in our sample of Ugandan adolescents and adults. Future studies should expand on this promising work by assessing additional psychometric characteristics of these translated measures in other communities in Uganda.
