Which therapy is primarily developed to treat depression by focusing on social relationships?

The therapy specifically developed to treat depression with an emphasis on social relationships is interpersonal therapy. This therapeutic approach is based on the understanding that interpersonal issues, such as conflicts with family and friends, grief, role transitions, and social isolation, significantly contribute to the development and maintenance of depressive symptoms.

Interpersonal therapy focuses on improving interpersonal functioning and resolving relationship problems, which can alleviate depressive symptoms and enhance overall emotional well-being. It is structured and time-limited, typically occurring over a course of 12 to 16 sessions, making it practical for individuals seeking relief from depression.

In contrast, other therapies mentioned in the choices address different concerns. Reality therapy focuses on personal responsibility and the choices individuals make to meet their needs. Existential therapy centers on issues of meaning, choice, and the human experience, often less structured than interpersonal therapy. Solution-focused therapy directs attention toward finding solutions and goals for the future rather than delving into current or past interpersonal problems. Therefore, interpersonal therapy stands out as the approach tailored specifically for addressing depression through the lens of social relationships.
