Objective: To explore the "active ingredient" of tinnitus therapy groups. Study design: The design was an inductive qualitative study informed by grounded theory. Eight participants, four from a tinnitus group and four from individual therapy with similar content, were invited to discuss their experiences of tinnitus therapy. The interviews were transcribed and analysed using a constant comparative approach. Results: The findings revealed that group experiences facilitate information exchange and social comparison, which facilitates coping. Conclusions: The human dynamics of groups may have an additional therapeutic benefit.
