Table 2 Overview of IMR pilot study (main feasibility objectives and outcomes)

From: Illness Management & Recovery (IMR) in the Netherlands; a naturalistic pilot study to explore the feasibility of a randomized controlled trial

  Objectives Outcome measures Feasibility criteria Outcomes
1 To include sufficient participants Monitoring; interviews 60 people 81 people included of 167, assessed for eligibility (49 %); sufficient for 6 IMR groups
2 Clients’ and clinicians’ satisfaction with IMR Interviews Satisfaction of most participants and clinicians with IMR Completers and trainers:(very) positive about IMR
3 IMR outcome (pre-post design) IMR Scale client version (Mueser et al. 2004) IMR Scale clinician version (Mueser et al. 2004) RMQ (Ridgway et al. 2003) Significant results on our outcome measures IMRS clinician version (p < 0.001, d = 0.84)a IMRS client version (p = 0.063; d = 0.41) RMQ (p = 0.003, d = 0.52)a.
4 Satisfactory fidelity IMR fidelity scale (Mueser et al. 2009) Total scores on the fidelity scale of at least 4.0. Total score (six groups): Mean (SD) = 4.0 (0.20) Three groups: total scores ≥ 4.0 Three groups: total scores < 4.0
5 Trainers' education and supervision Interviews Two-day training and Supervision of two hours per week Two-day course before start of the pilot; Supervision bi-weekly for two hours; Additional training 2 x per year for 4 h.
6 Dropout from IMR Monitoring; interviews Exploration, no targets set Dropout from IMR of 51 %
7 Duration of the IMR-program Monitoring; interviews Predictable; 9–12 months M = 12.7 months, SD = 3.14
