Chapter 6 142 Abstract Background Illness Management and Recovery (IMR) is a psychosocial intervention supporting people with serious mental illnesses. Objective To establish the implementation level of all IMR elements and explore complementarity of the IMR Treatment Integrity Scale (IT-IS) to the standard IMR Fidelity Scale. Methods In this study, 15 IMR groups were assessed for fidelity and clinician competency. Use of the IT-IS was adapted, similar to the IMR Fidelity Scale. Descriptive statistics were applied. Results Implementation success of IMR elements varied widely on the IMR Fidelity Scale and IT-IS (M = 3.94, SD = 1.13, and M = 3.29, SD = 1.05, respectively). Twelve IMR elements (60%) were well-implemented, whereas eight (40%) were implemented insufficiently, including some critical cognitive-behavioral techniques (e.g., roleplaying). The scales appeared largely complementary, though strongly correlated (r (13) = .74, p = .002). Conclusions Providing all IMR elements adequately requires a variety of clinical skills. Specific additional training and supervision may be necessary.
