The aim of this study was to investigate the effect of MPH treatment on bullying perpetration and victimization in children and adolescents with ADHD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Children and adolescents with ADHD, aged 8\u201316 years, who had not been treated for ADHD for at least 1 year and prescribed only MPH treatment were invited to participate in this open-label naturalistic study. After 3 months of MPH treatment, peer bullying involvement status was analyzed in comparison with the pretreatment data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There was a significant decrease in all subscales of the Conners' Parent Rating Scale (CPRS) and Conners' Teacher Rating Scale after MPH treatment. Being a bully decreased from 50% to 18% and being a victim decreased from 80% to 46%. It was determined that for every 1 point decrease in the CPRS Conduct Problems subscale, the risk of being a bully was reduced \u223c2-fold, and every 1 point decrease in the CPRS Anxiety subscale reduced the risk of being a victim 2.44-fold.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This is the first longitudinal study examining the effect of MPH treatment on bullying perpetration and victimization in children and adolescents with ADHD. It appears that MPH treatment may be effective in improving the situations of bullying perpetration and victimization in ADHD patients. In addition, the fact that the decrease in behavioral problems reduces the risk of being a bully and the decrease in anxiety symptoms reduces the risk of being a victim, suggests that prevention and intervention programs for bullying perpetration and victimization should target these problem areas.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/cap.2021.0119","type":"journal-article","created":{"date-parts":[[2022,3,4]],"date-time":"2022-03-04T11:26:10Z","timestamp":1646393170000},"page":"107-116","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["The Effects of Methylphenidate Treatment on Bullying Perpetration and Victimization in Children and Adolescents with Attention-Deficit\/Hyperactivity Disorder"],"prefix":"10.1177","volume":"32","author":[{"given":"Tolga","family":"Karaosman","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Sabuncuo\u011flu \u015eerefeddin Research and Training Hospital, Amasya University, Amasya, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2327-4050","authenticated-orcid":false,"given":"Yusuf Yasin","family":"Gumus","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Ondokuz May\u0131s University School of Medicine, Samsun, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,3,15]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.chi.0000155320.52322.37"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ab.20271"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00787-016-0881-y"},{"key":"e_1_3_3_6_1","first-page":"253","article-title":"Psychopharmacology and aggression","volume":"41","author":"Connor DF","year":"2002","unstructured":"Connor DF, , Glatt SJ, , Lopez ID, , Jackson D, , Melloni RH Jr.: Psychopharmacology and aggression.
