A systematic review of the effectiveness of psychoanalysis,psychoanalytic and psychodynamic psychotherapy with adults with intellectual and developmental disabilities: progress and challenges

Objectives: This systematic review aimed to critically appraise the literature on the efficacy and effectiveness of psychoanalysis, psychoanalytic and psychodynamic psychotherapy in adults with intellectual and developmental disabilities (IDD). Method: A systematic search of electronic databases was carried out. The methodological quality of the studies was assessed using a quality assessment tool and comparisons were made with a review of the quality of research on the effectiveness of cognitive behavioural therapy (CBT) for people with IDD. Results: The search yielded 13 papers which provided evidence for the effectiveness but not efficacy of psychoanalytic and psychodynamic psychotherapy; but none were found for psychoanalysis. The quality of the research was generally poor compared to the current research on the effectiveness of CBT. Conclusions: Positive outcomes have been indicated for psychoanalytic and psychodynamic psychotherapy with people with IDD. Larger scale, more controlled research is necessary to advance the evidence base.
