Objectives: The aim of this study was to investigate the variables that may affect treatment continuation in children aged 6 to 12 years who were newly diagnosed with ADHD. Methods: A total of 132 children diagnosed with ADHD and their parents participated in the study. Sociodemographic and clinical risk factors affecting continuation of treatment were examined using logistic regression analysis. Results: Multiple model examination revealed that greater age increased the risk of treatment discontinuation 1.824 times (p = 0.003) while a lower total length of paternal education increased the risk of discontinuation (1/0.835) 1.198 times (p = 0.022). Other variables emerging as significant in the univariate model lost that significance in the multiple model. Conclusions: Understanding the variables associated with medication discontinuation in ADHD in different populations and taking these variables into account in the development of health policies, will be useful in improving the long-term devastating effects of the disorder.
