中文摘要
新一波社会服务项目旨在帮助服务对象界定自己的目标,并在多年内以灵活而密集的方式支持他们实现这些目标,从而建立一条摆脱贫困的路径。我们对其中一个名为“通向成功之桥”(Bridges to Success)的项目开展了随机对照试验。两批参与者被随机分配到通常持续两年的密集、整体性、全方位服务组,而对照组则获得针对即时需求的帮助。由于该干预有明确的脱贫目标,但同时又具有整体性,我们预先设定了就业与非就业两类结果。随机分配三年后,对就业的测得处理效应为 9 ± 9 个百分点。一年后报告住房质量高的人群比例,其处理效应为 −2 ± 12 个百分点。在探索性分析中,额外证据表明,就业结果存在效应的证据强于非就业结果。一年后的就业处理效应为 10 ± 8 个百分点。将我们的数据与最相似的既有研究合并,相比任一单独研究都提高了估计精度,并表明此类项目可能产生中等程度的正向就业效应。另一方面,我们几乎没有发现证据表明,密集、整体性的服务会影响住房以外的各类其他非就业结果,即使其他生活领域正是参与者的主要目标。
Abstract
A new wave of social service programs aims to build a pathway out of poverty by helping clients define their own goals and then supporting them flexibly and intensively over multiple years to meet those goals. We conduct a randomized controlled trial of one such program, Bridges to Success. Two cohorts of participants were randomly assigned to intensive, holistic, wrap-around services that typically last two years versus a control offered help with an immediate need. Since the intervention has a clear goal of exiting poverty but is also holistic, we pre-specified both employment and non-employment outcomes. The measured treatment effect on employment three years after random assignment is 9 ± 9 percentage points (pp). The proportion of people reporting high housing quality after one year has a treatment effect of −2 ± 12 pp. In exploratory analysis, additional evidence suggests a stronger case for effects on employment than non-employment outcomes. Employment after one year shows a treatment effect of 10 ± 8 pp. Pooling our data with the most similar existing study increases precision relative to either study alone and indicates that such programs likely generate moderately positive employment effects. On the other hand, we find little evidence that intensive, holistic services affect any of a wide variety of other non-employment outcomes beyond housing, even when other areas of life are participants’ primary goals.
