Group therapy can be an effective mode of therapy, used on an inpatient unit, as it can allow patients to become allies in their journey to understand and overcome their mental health needs. The therapeutic principles discussed by Dr Irvin Yalom illustrate the significance and importance of group therapy, which was strongly incorporated into interactive behavior therapy (IBT) developed by Dr Daniel J Tomasulo. IBT is a type of group therapy, more action oriented, created to allow patients with intellectual disabilities (IDs) to better comprehend discussed topics, by designing and tailoring activities to meet their cognitive and linguistic capabilities. Additional details found in this article will illustrate the methods by which IBT is capable of meeting the needs of patients with ID. Such adjustments include shorter duration of activities to maximize concentration, proactive role-playing involving the synergistic effort of all members of the group, and limiting the authoritative role of the therapist in a group environment.
