背景资料：为了减轻低收入和中等收入国家围产期抑郁症的负担，卫生系统必须能够发现和治疗患有抑郁症的妇女。我们研究的目的是开发一种当地有效和可靠的筛查工具，用于识别马里农村地区患有抑郁综合征（dusukasi）的孕妇和幼儿母亲。方法：我们使用了一种适合当地情况的筛查工具，包括爱丁堡产后抑郁量表（EPDS）和霍普金斯症状自评量表（HSCL-25）中的项目。180名孕妇和2岁以下儿童的母亲在塞林盖，马里，以评估该工具的心理测量特性和有效性。项目反应理论被用来开发一个简短的版本的措施和这个简短的版本的效度和心理测量学特性进行了比较与全长scale.Results：完整的28个项目的规模表现出良好的内部一致性（Cronbach的α = 0.92）的单因素结构。在一项评估结构效度的已知群体分析中，自认为患有dusukasi的女性（n = 87）与未报告dusukasi的女性（n = 93）相比，抑郁和焦虑症状评分（p <0.0001）和功能障碍评分（p < 0.0001）显著更高。缩短的16项规模进行，以及在确定妇女dusukasi.Conclusions的完整规模：结构效度，我们适应的筛选工具的支持，以确定dusukasi在农村马里妇女。我们的方法可以应用于其他设置开发类似有效的筛查工具围产期抑郁症。
Background: In order to reduce the burden of perinatal depression in low- and middle-income countries, health systems must be able to identify and treat women suffering from depression. The objective of our study was to develop a locally valid and reliable screening instrument for use in identifying pregnant women and mothers of young children with a local depression syndrome, dusukasi, in rural Mali.Methods: We administered a locally adapted screening instrument containing items from the Edinburgh Postpartum Depression Scale (EPDS) and Hopkins Symptom Checklist (HSCL-25) to 180 pregnant women and mothers of children under age 2 in Selingue, Mali to assess the instrument's psychometric properties and validity. Item Response Theory was used to develop an abbreviated version of the measure and the validity and psychometric properties of this shortened version were compared with the full-length scale.Results: The full 28-item scale exhibited a single factor structure with good internal consistency (Cronbach's alpha = 0.92). Women who self-identified as suffering from dusukasi (n = 87) in a known groups analysis to assess construct validity had significantly higher depression and anxiety symptom scores (p < 0.0001) and functional impairment scores (p < 0.0001) compared to women not reporting dusukasi (n = 93). The shortened 16-item scale performed as well as the full scale in identifying women with dusukasi.Conclusions: Construct validity of our adapted screening instrument was supported for identifying dusukasi in rural Malian women. Our methodology can be applied in other settings to develop similarly valid screening instruments for perinatal depression.
