Welcome

Welcome to my website

I am a clinical psychologist and psychotherapist. My original background is in family and systemic therapy, cognitive and behavioral therapy, and hypnosis. I am a supervisor for the Dutch Society for Hypnosis and the Dutch Society for Partner and Family Therapy. I have worked extensively at both inpatient and outpatient psychiatric facilities.

Since the late eighties, I have specialized in the diagnosis and treatment of patients with histories of early psychological trauma, in particular patients with complex dissociative disorders. I validated, together with Nel Draijer, the Dutch translation of the Structured Clinical Interview for DSM-IV Dissociative disorders (Boon & Draijer, 1993).

More recently, I developed a skills training manual for patients with a complex dissociative disorder, together with Kathy Steele and Onno van der Hart. I am currently working on a new diagnostic interview to assess chronic trauma-related disorders, in particular the dissociative disorders – the Trauma and Dissociation Symptoms Interview (TADS-I).

I offer workshops and training on the topic of psychological trauma and the diagnosis and treatment of dissociative disorders. I also offer supervision and consultation services to (teams of) professionals treating severely traumatized patients and their families, both at inpatient and outpatient treatment facilities.


WHAT’S NEW?

I have recently started a preliminary study with the Trauma and Dissociation Symptoms Interview (TADS-I, Boon & Mathess, 2016) with my Dutch colleague Marjolein Runhaar. For further information on the TADS-I click here.
