This study examined the role of theoretically meaningful mediators of therapeutic change-interpretation bias, perceived control, and coping strategies-in a cognitive-behavioral intervention for anxious youth. This is one of the few studies that examined the change in potential mediator and outcome variables by means of a longitudinal design that included four assessment points: pretreatment, in-treatment, post-treatment, and at 4-months follow-up. Forty-seven 8- to 12-year-old children with a principal DSM-IV diagnosis of anxiety disorder participated in the study. On each assessment point, questionnaires assessing the mediator variables and a standardized anxiety scale were administered to the children. The results showed that perceived control and interpretation bias (but not coping strategies) accounted for a significant proportion in the variability of various types of anxiety symptoms, providing a preliminary support for the notion that these cognitive dimensions' act as mechanisms of therapeutic change in cognitive-behavioral therapy for anxious children.
本研究考察了治疗改变的理论意义上的中介因素——解释偏差、感知控制和应对策略——在针对焦虑青少年的认知行为干预中的作用。这是少数几项通过纵向设计来考察潜在中介变量和结果变量变化的研究之一，该纵向设计包括四个评估点：治疗前、治疗中、治疗后以及4个月随访。47名主要诊断为DSM-IV焦虑症的8至12岁儿童参与了该研究。在每个评估点，都向儿童发放了评估中介变量的问卷和一份标准化焦虑量表。结果表明，感知控制和解释偏差（而非应对策略）在各类焦虑症状的变异性中占很大比例，这为以下观点提供了初步支持：在针对焦虑儿童的认知行为疗法中，这些认知维度充当了治疗改变的机制。
