About me
Dr. Rosie Marsh
Clinical Psychologist
I work closely with patients in the treatment and diagnosis of a range of mental health conditions such as depression, anxiety, PTSD, substance use disorders, and various dissociative disorders.
I have been conducting ADHD assessments since 2016 and have expertise in evaluating dissociative identity disorder.
I am registered with the New Zealand Psychologists Board under the clinical scope and hold professional memberships with the New Zealand Psychological Society (NZPsS).
I hold a Ph.D. from the University of Groningen and the University of Canterbury, with a focus on dissociative identity disorder. My research has been published in the Journal of Abnormal Psychology, PLoS One, and Frontiers in Psychology. I have also delivered lectures in psychology at the University of Otago and the University of Canterbury, and have conducted workshops for the NZ College of Clinical Psychologists (NZCCP) on comprehensive assessment and treatment of dissociative identity disorder, and treatment of complex PTSD.
My therapeutic methods include evidence-based approaches:
Cognitive Behavioral Therapy (CBT)
Acceptance and Commitment Therapy (ACT)
Motivational Interviewing (MI)
Eye Movement Desensitization Reprocessing (EMDR)
Cognitive Processing Therapy (CPT)
