Malpractice issues in psychotherapy and psychological treatments refer to the unethical behavior of a psychologist or psychotherapist toward the patient. The current study reviewed complaints directed at psychologists and psychotherapists in Sweden with regard to possible incidents of malpractice. Eligible cases were retrieved from a database managed by the Health and Social Care Inspectorate [Inspektionen för vård och omsorg (IVO)], an administrative authority responsible for the safety and quality of healthcare and social services delivery. These cases were analyzed using thematic (...) analysis. In total, 33 complaints matched the keywords proposed by IVO, and were scrutinized in detail. The cases primarily involved psychiatric care by a psychologist in outpatient settings, although many cases comprised multiple healthcare providers responsible for the patient’s care, or targeted the healthcare unit as a whole. The results demonstrated that different forms of malpractice occur, and can be classified in two general themes, Incorrect administration and implementation and Attitude and behavior, which involve organizational aspects as well as examples of malpractice and unethical behavior. Implications for clinical practice and future research include further training in ethics and malpractice, video recording or auditing sessions, routine outcome monitoring, and providing patients with information on how to file complaints.
