The purpose of this article is to describe therapeutic factors that constitute mechanisms of change in group intervention. These therapeutic factors occur in groups with varied populations in varied settings and have important implications for group approaches to aural/audiologic rehabilitation. Factors included in the review are universality, instillation of hope, imparting information, altruism, imitative behavior, group cohesion, interpersonal learning, development of socializing techniques, recapitulation of the family, catharsis, and existential issues. The discussions largely are based on Irvin Yalom’s therapeutic factors but include references from a wide-range of sources throughout the medical, psychological, and rehabilitative fields.
