    • Causal modelling of variation in clinical practice and long-term outcomes of ADHD using Norwegian registry data: The ADHD controversy project 

      Mykletun, Arnstein; Widding-Havneraas, Tarjei; Chaulagain, Ashmita; Lyhmann, Ingvild; Bjelland, Ingvar; Halmøy, Anne; Elwert, Felix; Butterworth, Peter; Markussen, Simen; Zachrisson, Henrik Daae; Rypdal, Knut (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-19)
      <p><i>Introduction:</i> Attention-deficit/hyperactivity disorder (ADHD) is among the most common mental disorders in children and adolescents, and it is a strong risk factor for several adverse psychosocial outcomes over the lifespan. There are large between-country and within-country variations in diagnosis and medication rates. Due to ethical and practical considerations, a few studies have examined ...

    • Effect of ADHD medication on risk of injuries: a preference-based instrumental variable analysis 

      Widding-Havnerås, Tarjei; Elwert, Felix; Markussen, Simen; Zachrisson, Henrik Daae; Lyhmann, Ingvild; Chaulagain, Ashmita; Bjelland, Ingvar; Halmøy, Anne; Rypdal, Knut; Mykletun, Arnstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)
      ADHD is associated with an increased risk of injury. Causal evidence for efects of pharmacological treatment on injuries is scarce. We estimated efects of ADHD medication on injuries using variation in provider preference as an instrumental variable (IV). Using Norwegian registry data, we followed 8051 patients who were diagnosed with ADHD aged 5 to 18 between 2009 and 2011 and recorded their ADHD ...

    • Effect of Pharmacological Treatment of Attention-Deficit/Hyperactivity Disorder on Criminality 

      Widding-Havnerås, Tarjei; Zachrisson, Henrik Daae; Markussen, Simen; Elwert, Felix; Lyhmann, Ingvild; Chaulagain, Ashmita; Bjelland, Ingvar; Halmøy, Anne; Rypdal, Knut; Mykletun, Arnstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-27)
      Objective: Criminality rates are higher among persons with attention-deficit/hyperactivity disorder (ADHD), and evidence that medication reduces crime is limited. Medication rates between clinics vary widely even within universal health care systems, partly because of providers’ treatment preferences. We used this variation to estimate causal effects of pharmacological treatment of ADHD on 4-year ...

    • Estimating the Consequences of Norway’s National Scale-Up of Early Childhood Education and Care (Beginning in Infancy) for Early Language Skills 

      Dearing, Eric; Zachrisson, Henrik Daae; Mykletun, Arnstein; Toppelberg, Claudio O (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-01)
      While most early childhood education and care (ECEC) programs taken to scale in the United States have served socially disadvantaged 3- to 5-years-olds, Norway scaled up universal ECEC from age 1. We investigated the consequences of Norway’s universal ECEC scale-up for children’s early language skills, exploiting variation in ECEC coverage across birth cohorts and municipalities in a population-based ...

    • Variation in attitudes toward diagnosis and medication of ADHD: a survey among clinicians in the Norwegian child and adolescent mental health services 

      Lyhmann, Ingvild; Widding-Havnerås, Tarjei; Zachrisson, Henrik Daae; Bjelland, Ingvar; Chaulagain, Ashmita; Mykletun, Arnstein; Halmøy, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-19)
      Prevalence and medication rates of ADHD vary geographically, both between and within countries. No absolute cutof exists between ADHD and normal behavior, making clinician attitudes (leading to local practice cultures) a potential explanation for the observed variation in diagnosis and medication rates. The objective of this study was to describe variation in attitudes toward diagnosis and medication ...
