Background: The aims were to identify referral characteristics and outcomes for people with intellectual disabilities referred to a psychodynamic psychotherapy service. Materials and Methods: A retrospective case notes review of anonymized data relating to 100 sequential patient episodes. Results: A total of 81 people out of 100 with a range of intellectual disabilities from mild to severe were assessed as suitable for therapy; 66 were eligible for individual, art, or group therapy. Common reasons for referral were: trauma/abuse, bereavement, depression and challenging behaviour. Many people had more than one cause for referral and/or co-morbid psychiatric diagnoses. Indicators of success included: increased daily living skills, improved confidence, self-esteem and behaviour, and finding employment. Conclusions: This study confirms findings from other studies that psychotherapy is possible in people with mild to severe intellectual disability with clinically recorded outcomes ranging from reductions in problem behaviours to getting a job.
