The purpose of this study is to estimate the observed incidence of the health outcomes (suicide attempt or ideation, suicide ideation, suicide attempt, psychosis, and substance abuse) in a cohort of participants diagnosed with attention deficit hyperactivity disorder (ADHD) who are first-line new therapy with methylphenidate monotherapy, lisdexamfetamine monotherapy, atomoxetine monotherapy, amphetamine/dextroamphetamine combo therapy, and either methylphenidate/lisdexamfetamine/atomoxetine monotherapy or amphetamine/dextroamphetamine combo therapy during the 'on treatment' period from 7 days after the start of exposure through the end of exposure (treatment discontinuation for at least 60 days) and the 'intent to treat' period from 7 days after start of treatment to end of continuous observation; and to compare the hazards of outcomes (suicide attempt or ideation, suicide ideation, suicide attempt, psychosis, and substance abuse) in the target cohort (participants diagnosed with ADHD who are first-line monotherapy new users of methylphenidate) versus each comparator cohort (patients diagnosed with ADHD who are first-line newly exposed to lisdexamfetamine monotherapy, atomoxetine monotherapy, amphetamine/dextroamphetamine combo therapy) during the 'on treatment' period from 7 days after the start of exposure through the end of exposure (treatment discontinuation for at least 60 days) and the 'intent to treat' period from 7 days after start of treatment to end of continuous observation.
