By 2009, two decades of war and widespread displacement left the majority of the population of Northern Uganda impoverished.
This study used a cluster-randomized design to test the hypothesis that a poverty alleviation program would improve economic security and reduce symptoms of depression in a sample of mostly young women. Roughly 120 villages in Northern Uganda were invited to participate. Community committees were asked to identify the most vulnerable women (and some men) to participate. The implementing agency screened all proposed participants, and a total of 1800 were enrolled. Following a baseline survey, villages were randomized to a treatment or wait-list control group. Participants in treatment villages received training, start-up capital, and follow-up support. Participants, implementers, and data collectors were not blinded to treatment status.
Villages were randomized to the treatment group (60 villages with 896 participants) or the wait-list control group (60 villages with 904 participants) with an allocation ration of 1:1. All clusters participated in the intervention and were included in the analysis. The intent-to-treat analysis included 860 treatment participants and 866 control participants (4.1% attrition). Sixteen months after the program, monthly cash earnings doubled from UGX 22 523 to 51 124, non-household and non-farm businesses doubled, and cash savings roughly quadrupled. There was no measurable effect on a locally derived measure of symptoms of depression.
Despite finding large increases in business, income, and savings among the treatment group, we do not find support for an indirect effect of poverty alleviation on symptoms of depression.
到2009年,二十年的战争和大规模流离失所使乌干达北部的大多数人口陷入贫困。
本研究采用整群随机设计,以检验一项扶贫计划能否改善经济安全状况并减轻以年轻女性为主的样本中的抑郁症状这一假设。乌干达北部约120个村庄受邀参与。社区委员会被要求确定最脆弱的女性(以及一些男性)参与。实施机构对所有拟参与者进行了筛查,共招募了1800人。在基线调查之后,村庄被随机分为治疗组或等待名单对照组。治疗组村庄的参与者接受培训、启动资金和后续支持。参与者、实施者和数据收集者对治疗状态未设盲。
村庄被随机分为治疗组(60个村庄,896名参与者)或等待名单对照组(60个村庄,904名参与者),分配比例为1:1。所有群组都参与了干预并纳入分析。意向性分析包括860名治疗参与者和866名对照参与者(损耗率为4.1%)。该计划实施16个月后,月现金收入从22523乌干达先令增至51124乌干达先令,翻了一番,非家庭和非农业企业数量翻倍,现金储蓄大致增至四倍。对当地得出的抑郁症状指标没有可测量的影响。
尽管发现治疗组的商业、收入和储蓄大幅增加,但我们并未找到证据支持扶贫对抑郁症状有间接影响。
