Katie Aafjes-van Doorn

katie-aafjes-van-doorn-360x450Throughout my career as Clinical Psychologist I have stayed involved in clinical practice, teaching and research. After receiving my MSc in Clinical Psychology at the University of Amsterdam, the Netherlands in 2005, I moved to the United Kingdom (UK). I earned a MSc in Psychological Research, followed by a doctorate in Clinical Psychology at University of Oxford, and gained licensure in the UK. Joining my husband in his move from the Netherlands to the UK and later from the UK to California has required me to focus on (re) gaining clinical licensure in the different countries. I just completed accruing all clinical hours for licensure at Access Institute, a well renowned psychoanalytic therapy clinic in San Francisco. In September 2016 I started work as a postdoctoral research fellow with Dr. Jacques Barber and his lab at Adelphi University, New York. Here, I will continue to develop my research program on trans-theoretical mechanism of change in psychotherapy, including the coding and analyses of affect experiencing, defenses, learning style and other potential moderators and mediators of change.

During my training years in the Netherlands and the UK I worked in a variety of clinical settings, with different modalities (CBT, CAT, DBT, EDT) and patient groups (i.e. adults, older adults, children) and developed a strong interest in psychodynamic therapy in particular. At Oxford, I, for example, sought out a one-year specialist internship in Experiential Dynamic Therapy and conducted my dissertation research on the effect of this approach in NHS community outpatient services. When I arrived in California, I participated in a year-long Psychoanalytic Psychotherapy-training program at the San Francisco Center for Psychoanalysis and taught ‘psychoanalytic theory’ and ‘psychodynamic therapy’ to graduate students.

Alongside my clinical work, I have always maintained a strong involvement in clinical-research projects and have set up practice-based studies in my spare time. This has resulted in a number of publications and I have several others currently in the pipeline. Where possible, my research endeavors have been collaborative efforts with students, clinicians and researchers. Learning from international collaborations (Sweden, Norway, Canada, Argentina, The Netherlands, UK & USA) has been especially inspiring to me and no doubt will continue to broaden my view of Clinical Psychology and Psychotherapy.
