This article consists of a review of 16 research studies on treatments in school settings for children with attention deficit hyperactivity disorder (ADHD) carried out in the last decade. It includes both simple interventions and multicomponent interventions where different techniques are combined. Based on this revision, the conclusion is drawn that, based on the evidence, school-based treatments for ADHD are effective in the short run for reducing disruptive behaviors and improving on-task behavior and academic performance of children with ADHD. Issues regarding the limitations to generalizing the improvements over time and across content areas are discussed. Furthermore, results from the MTA-a study designed to compare the efficacy of behavioral treatment (BT), medical management (MM), combined treatment (BT and MM), and a routine community care control group-are discussed. The MTA findings suggest that the most effective treatment for ADHD is a multimodal intervention that frequently includes concurrent medication in addition to parent training, school interventions, and child intervention.The notable increase in the number of children diagnosed with attention deficit hyperactivity disorder (ADHD) in the past few years has had important repercussions on the educational system. In fact, in the United States, additional expenditures by public schools on behalf of students with ADHD amounted to over $3.2 billion in 1995 (Forness, 1998). Consequently, in addition to becoming a public health issue, ADHD has also become a relevant educational issue. Furthermore, after decades of research, there is no doubt that ADHD has a chronic nature. It shows up in early childhood and continues to a troubling degree throughout childhood and adolescence and into adulthood. The symptoms of this disorder cause alterations in school and family functioning and in relationships with classmates, and they carry with them a poor long-term psychiatric, social, and academic adjustment (Biederman et al., 2004).Given the high prevalence of ADHD, its long-term repercussions, and its chronicity, the search for effective treatments to manage it has been a constant concern for the last EXCEPTIONALITY, 14(1), [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]
