Areas of expertise

Mathijs Lucassen, PhD, MHSc(Hons), PGDipHSc (Child and Adolescent Mental Health), BOccThy (Distinction), DipOT (Distinction) is a researcher and an educator. In 2005 he published a book (Child and adolescent mental health in Aotearoa/New Zealand:  An overview) with Professor Sally Merry and Dr Iain Doherty.  In that year he published findings on his investigation into whether a workshop on child and adolescent mental health positively influenced nursing, occupational therapy and social work students’ career intentions.


Mathijs has co-authored reports and several studies with the Adolescent Health Research Group (e.g. a paper entitled “The Health and Well-Being of Transgender High School Students: Results From the New Zealand Adolescent Health Survey (Youth'12)” in 2014).  For his PhD he evaluated a form of computerised cognitive behavioural therapy with sexual minority youth with depressive symptoms.  He was a research fellow and lecturer in the Department of Psychological Medicine.  He was also the study manager for a randomised controlled trial of MATCH (Modular Approach to Therapy Children with Anxiety, Depression, Trauma-related symptoms and Conduct issues) in outpatient child and adolescent mental health services. He is currently a senior lecturer in mental health at The Open University in the UK.
