Interaction structures as predictors of outcome in a naturalistic study of psychodynamic child psychotherapy.

Objective: The first aim of this study was to identify interaction structures (IS), which refer to clusters of items characterizing the course of psychotherapy in terms of reciprocal interaction patterns between the therapist and the child, secondly to assess their trends over the course of treatment, and finally investigate which IS predict outcome in long-term psychodynamic child psychotherapy.Method: The sample included 52 children with externalizing and internalizing problems. 192 sessions were rated with the use of the Child Psychotherapy Q-Set (CPQ). Outcome was assessed with the Child Behavior Checklist (CBCL) Total Problems, and Children's Global Assessment Scale (CGAS).Results: A principal components analysis resulted in four IS, theoretically named Therapeutic Alliance, Children's Emotion Expression, Child -Centered Technique and Psychodynamic Technique. Multilevel Modeling (MLM) analyses indicated significant linear growth on Psychodynamic Technique. Multiple regression analyses indicated that Psychodynamic Technique positively predicted changes on CBCL Total Problems and CGAS. In contrast, Child-Centered technique negatively predicted change on CBCL Total Problems, however follow up interaction analyses showed that externalizing children who received more Child-Centered technique showed more improvement on this scale.Discussion: Findings point to empirically derived components of psychodynamic child psychotherapy and provide preliminary answers about which aspects may facilitate change.

Mentalization and the growth of symbolic play and affect regulation in psychodynamic therapy for children with behavioral problems.

Objective: Children with behavioral problems often have problems with symbolic play organization, specifically with the regulation of negative affect and its representation. One of the aims of psychodynamic therapy with these children is enhancing their symbolic and mentalizing capacities in play. This study investigated the associations between promoting mentalization, and the growth of symbolic play and affect regulation. Method: The sample included 48 children with behavioral problems, who underwent long-term psychodynamic treatment informed with mentalization principles, with good outcome. Three hundred twenty-nine sessions were coded for children's symbolic play and affect regulation strategies, and each treatment was rated for adherence to mentalizing principles. Results: Hierarchical linear modeling showed quadratic growth of variables, wherein symbolic play initially increased followed by a deceleration in change, whereas affect regulation initially decreased followed by an increase. Adherence to mentalizing principles was associated with both symbolic play and affect regulation. A two-way interaction between time in treatment and adherence to mentalization showed that in high adherent treatments, affect regulation increased towards the end of treatment, whereas in low adherent treatments, there was no change. Conclusion: Results show support for the association between adherence to mentalization and growth of affect regulation and symbolic play in psychodynamic therapy.
