Group treatment is explored in light of its psychosocial context, treatment effectiveness, and efficiency. A summary of the four group treatment approaches (two for children, two for adults) for communicative disorders are provided: classroom-based elementary school group, multicultural and multilinguistic preschool group, alaryngeal speech rehabilitation and support group, and cooperative group treatment for adults with aphasia. Similarities and differences among the group treatments are presented. Similarities include group processes, communication goals, psychosocial skills, accountability, and naturalistic context. Among the differences are settings for treatment, collaborative versus independent service delivery models, the components of functional communication, group size, group composition, and customized therapy techniques. Role-playing, routines and scripts, themes, authentic vocabulary, and cooperative methods are techniques useful to group therapy. Key words: alaryngeal speech rehabilitation, aphasia, communication skills, group treatment, multilingual/multicultural group.
