Research interests

Couple and family therapy at the Family Department, Modum Bad:

(a) Research on the relationship between individual symptom distress (e.g., depression and trauma) and severe relational issues within the couple or family.

(b) Factors contributing to desired change during treatment and maintained after treatment completion.

(c) Understanding reasons why couples and families do not experience desired change as a result of treatment at the Family Department, and the implications this should have for changes in the treatment approach. This research is highly relevant to the focus that should be in therapy, given that the patient group at the Family Department is characterized by such a combination of disorders. Several scientific articles on this topic are in progress.
