Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
