功能性行为评估对孤独症儿童问题行为的个案干预研究——Tau-U指标的应用

Case Intervention Study on Problem Behavior in Children with Autism by Functional Behavior Assessment——The Application of the Tau-U Metrics

孤独症儿童问题行为相当普遍,其中自伤性行为、攻击性行为和自我刺激行为发生频率高,其破坏性和危险性令人担忧。研究通过功能性行为评估,分析学前(2-5岁)孤独症儿童三种典型问题行为背后的功能原因,设计相应的干预方案,采用单一被试A-B-A倒返实验设计对问题行为进行干预。采用单一被试研究数据分析指标Tau-U进行分析,数据显示,经过4周干预,三名学前孤独症儿童问题行为的发生频率显著降低,干预有效。研究表明应用功能性行为评估诊断孤独症儿童问题行为,据此实施干预可有效减少问题行为,促进其适应性行为建立。

Problem behaviors of children with autism are quite common,among which self-injurious behaviors,aggressive behaviors and self-stimulating behaviors occur frequently,and their destructiveness and risk are worrisome.Through functional behavior assessment,this study analyzed the functional reasons behind three typical problem behaviors of preprimary children with autism(2-5 years old),designed corresponding intervention programs,and used a single subject the A-B-A Reversal-Replication experimental design to intervene the problem behaviors.Tau-U,a single subject study data analysis index,was used for analysis.The data showed that after 4 weeks of intervention,the frequency of problem behaviors of three autistic children was significantly reduced,and the intervention was effective.Studies have shown that the application of functional behavior assessment to diagnose the problem behavior of preprimary children with autism,and the implementation of intervention based on this can effectively eliminate the problem behavior and promote the establishment of adaptive behavior.
