FOLLOW-UP OF THE MULTIMODAL TREATMENT STUDY OF CHILDREN WITH ATTENTION DEFICIT H

本合同的目的是通过对参与多动症儿童多模式治疗研究（MTA）的受试者进行系统随访，研究不同治疗方式对多动症儿童的长期效果。MTA研究的初始设计和规划阶段发生在1992年下半年至1993年底，在此期间，不同研究人员的不同研究设计和目标被融合成一个有凝聚力的、连贯的、科学严谨的最终设计。这项为期24个月的MTA研究（14个月的治疗，随后10个月的随访评估）在接下来的四年中，在7个治疗地点对579名多动症儿童进行了研究。参与者在14个月治疗前、治疗期间、治疗结束时以及治疗10个月后分别接受评估。接受治疗取决于四组参与者中的哪一组是随机的（单独药物治疗，单独行为治疗，药物加行为治疗，照常社区治疗）。这五年期间是由NIMH合作协议资助给临床站点的。在24个月时，加入一个由年级和学校匹配的非患者组成的地方规范对照组作为比较组。在每个站点随后的竞争性补充的支持下，完成了36个月的后续评估。

The purpose of this contract is to study the long-term effects of different treatment modalities for children with attention deficit hyperactivity disorder (ADHD) through a systematic follow-up of the subjects who participated in the Multimodal Treatment Study of Children with ADHD (MTA). The initial design and planning phase of the MTA study occurred during the latter portion of 1992 thru the end of 1993, where the divergent study designs and goals of the various investigators were blended into a cohesive, coherent, and scientifically rigorous final design. The 24-month MTA Study (14 months of treatment, followed by a 10-month follow-up assessment) of 579 children with ADHD was conducted at seven treatment sites over the course of the next four years. Participants were assessed before, during, and at the end of 14 months of treatment, and 10 months later. Treatment was received depending on to which one of four groups participants were randomized (medication alone, behavioral treatment alone, medication plus behavioral treatment, community treatment as usual). This five-year period was supported by NIMH cooperative agreement grants to the clinical sites. At the 24-month point, a Local Normative Control Group of grade- and school-matched non-patients was added as a comparator group. With the support of a subsequent competing supplement to each site, 36-month follow-up assessments were completed. The original MTA aims addressed the following questions: What are the differences in effectiveness for medication management versus intensive behavioral treatments? What are the additive/synergistic effects of combined medication and psychosocial treatment compared to either treatment delivered alone? What is the relative effectiveness of systematic, well-delivered treatments vs. ¿standard¿ treatments typically received in the community? Additional questions the MTA investigators sought to address included the prediction and mediation of treatment-related gains from individual (e.g., co-morbidity), familial (e.g., child-rearing practices), and/or social (e.g., SES) variables. This current contract supports assessment and data collection for follow-up year 12 of the MTA study, at the seven original sites. Each site is supported by an individual contract to that site.
