Psychotherapy which are intended for patients with mental health issues face problems in terms of limited duration and intensity of therapy. This occurs due to several conditions, such as a lack of psychiatric resources, required communication with several multidisciplinary groups, complex procedures, and lack of patient discipline. This study aims to choose the right alternative Internet of Things (IoT) technology that can be implemented in psychotherapy services in psychiatric hospital by taking into account the criteria of Internet of Things implementation. IoT for psychotherapy can help a psychiatrist to provide intensive care with minimal supervision, improve quality measurements with real-time evidence of results, and identify faster recovery. The Best Worst Method (BWM) is used to obtain the weight of each criteria and sub-criteria for applying IoT. The Complex Proportional Assessment Method (COPRAS) is used to determine the priority technology that can be applied. This research results four priority of IoT technology that can be implemented in psychotherapy services in psychiatric hospital.
