background The prevalence of psychological problems in people with (visual and) intellectual disabilities is high and therefore there is a substantial need for adequate psychological treatment.
aim To examine the effectiveness of psychotherapy in people with a (visual and) intellectual disability and to study which adjustments are needed in treatment protocols.
method A random selection of client files (n = 50) was studied, therapists completed questionnaires (n = 5) and videos of mentalisation based therapy sessions (n = 12) were analysed.
results A qualitative assessment of therapy effect showed that for 88% of clients therapy was effective, half or all treatment goals were achieved. The psychotherapeutic methodologies corresponded, as recommended in the literature, to methodologies used for persons without a disability, although practical and specific adjustments were needed.
conclusion A large number of psychotherapeutic methods, with the necessary adjustments, can be used in the treatment of persons with (visual and intellectual) disabilities with psychological problems.
