摘要
随机对照试验被广泛视为社会工作干预的黄金法则。但是,由于在干预对象数量、实施规范、质量评价工具等方面的条件制约,以及社会工作的伦理要求,现实情境中的社会工作干预往往难以实现严格的随机对照试验。基于一个针对儿童积极行为发展的“让我们做朋友—河北”干预项目实施全过程的分析显示,在随机对照试验受到限制的情况下,可以在干预方案设计、干预实施和干预效果评价等不同环节选择非随机干预次优策略,这些次优策略也展现出了比较明显的干预效果。此外,在社会工作服务领域,统计学意义与临床意义应共同成为衡量干预效果的核心标准。
Randomized controlled trial is widely regarded as the golden rule of social work interventions.However,due to constraints in terms of the number of intervention participants,implementation norms,quality assessment tools and the ethical requirements of social work,it is often difficult to achieve a rigorous randomized controlled trial of social work interventions in real-life contexts.An analysis of the implementation of the"Let's Be Friends-Hebei"intervention for children's positive behavioural development shows that,non-randomized intervention sub-optimal strategies can be selected in different stages of intervention design,implementation and evaluation,and these sub-optimal strategies also show relatively significant intervention effects.In addition,in the field of social work services,statistical significance and clinical significance should be the core criteria for measuring the effectiveness of interventions.
