Final answer:
The Interpersonal Triad in IPT consists of grief, role disputes, and role transitions, focusing on improving interpersonal functioning and addressing issues related to loss, conflict, and life changes.
Step-by-step explanation:
The Interpersonal Triad in Interpersonal Psychotherapy (IPT) refers to the three problem areas that the therapy focuses on to improve interpersonal functioning. These are: grief, role disputes, and role transitions. Grief is addressed in IPT when a person is struggling to come to terms with the loss of a loved one, which can cause various emotional disturbances. Role disputes occur when a person has non-reciprocal expectations of their role within a relationship, leading to ongoing conflicts and stress. Finally, role transitions refer to the difficulties that arise when a person must adapt to a significant change in life circumstances, such as divorce, retirement, or moving to a new place.
