Psychotherapeutic Change Mechanisms and Causal Psychotherapy: Applications to Child Abuse and Trauma.

The study of change mechanisms in psychotherapy needs to be integrated with the causality of behavior, which leads to the concept of causal psychotherapy. Causal psychotherapy is posited as a useful adjunct to standard, evidence based psychotherapies for child and youth victims of abuse and trauma. The article illustrates six processes that could be involved in causal psychotherapy in this context, from the distal to the proximal. They include the distal mechanism of activation-inhibition coordination. The most proximal one relates to executive function. The intermediate levels include ones related to co-regulation (e.g., self control), analysis-synthesis, objectivity-subjectivity, and psychological reserve, which is a new concept in the domain of psychological change mechanisms. Each of the variables can vary from high to low, with the low end being more problematic. Psychotherapy can aim to bring the patient toward adaptive levels. The literature review focuses on psychotherapeutic change mechanisms, and standard psychotherapies for child/youth abuse/trauma, especially trauma-focused cognitive behavior therapy (TF-CBT). Then, it considers causal aspects of child/youth abuse and trauma, including PTSD. The discussion relates causal therapy to the question of unifying psychology and psychotherapy under the rubric of causality as a core integrative mechanism.
