IMR is organized into modules, each covering a different topic. The modules are premised on the stress-vulnerability model of mental illness (
2,
4), in which mental illness is thought to be affected by both biological vulnerabilities and psychosocial stressors. Therefore, the modules include information on mitigating these vulnerabilities and stressors as well as developing “recovery strategies,” such as relapse prevention plans. The third edition of IMR includes 11 modules covering the following topics: recovery, practical facts about mental illness, the stress-vulnerability model, building social support, using medication effectively, drugs and alcohol, reducing relapses, coping with stress, coping with persistent symptoms, getting your needs met in the mental health system, and living a healthy lifestyle. Each module uses a combination of motivation-based, educational, and cognitive-behavioral strategies and requires several sessions to teach. IMR can be delivered in a group or an individual format over approximately six months to one year.
Resource materials have been developed to facilitate the implementation of IMR (
5). They include a practitioner’s guide; the IMR workbook, with educational handouts for each topic; an IMR fidelity scale; outcome measures; informational brochures for different stakeholders, such as consumers, family members, clinicians, and policy makers; and introductory and demonstration videos. The program and the resource materials are now publicly available for free from the Substance Abuse and Mental Health Services Administration (SAMHSA) Web site.
IMR has established a strong empirical foundation by incorporating evidence-based strategies for improving illness self-management. Unlike other practices in the NIEBP project, the IMR program and resource materials had not been previously evaluated as a complete package. Since SAMHSA made the materials available online, IMR has been increasingly implemented nationally and internationally and has been the focus of growing research. This article provides a systematic review of research on the IMR program, including the effects of IMR on consumer outcomes and service utilization, implementation of IMR, and modifications of the program.
Methods
In June 2011 we searched Embase, MEDLINE, PsycINFO, CINAHL, and the Cochrane Library (Cochrane Central Register of Controlled Trials, the Health Technology Assessment database, and the Database of Abstracts of Reviews of Effects) by using the keywords “illness management and recovery,” “wellness management and recovery,” or “IMR” AND (“schizophrenia” OR “bipolar” OR “depression” OR “recovery” OR “mental health”), generating 37 references after removal of duplicates. We also searched for publications citing two seminal IMR articles (
1,
2), resulting in 223 publications after removal of duplicates. The inclusion criteria for our review included publications that dealt explicitly with IMR or described the program of study as an adaptation of IMR. Publications that simply described the creation of the IMR program were excluded. We also excluded reports that were not published in peer-reviewed journals to ensure the highest scientific rigor.
Twenty-six studies met inclusion criteria, including nine that measured consumer outcomes and 16 that examined implementation or adaptations of IMR. One study, by Roe and colleagues (
6), was a qualitative follow-up of a prior study (
7) and did not report unique quantitative consumer outcomes; however, because it provided implementation outcomes (completion rates), we included it in the review of implementation studies.
Discussion
This review yielded a substantial amount of research on IMR. Nine studies of client outcomes and 16 implementation studies have been published since the creation of the program. Research has spanned numerous treatment settings across several continents. Outcomes research examined whether there were changes in consumer outcomes before and after participating in IMR, with three RCTs comparing IMR to treatment as usual.
IMR appears to be a successful and well-tolerated intervention for people with severe mental illness. The most consistently positive findings were improved scores on the IMRS, which was specifically designed to assess IMR outcomes and objectively rated symptoms. Other evaluations of consumer-reported recovery were generally—but not uniformly—positive. Other subjective and objective outcomes varied considerably among studies.
Although the current research is promising, modifications to future studies could greatly enrich the information gleaned about IMR and its potential applications. First, the three RCTs did not compare IMR consumers to an active control group; therefore, the results cannot disentangle specific effects of IMR from common factors. Moreover, “treatment as usual” was often poorly delineated; therefore, it is unclear whether adding IMR to a treatment regimen would have added benefits. Other services utilized by participants before and concurrently with IMR should be tracked and taken into account before implementing new programs.
Second, IMR is a complex and multifaceted intervention, with potential effects on multiple consumer domains and various mechanisms of action. The studies generally included multiple outcomes, but they did not provide a clear linkage between the relevant element of IMR and its putative outcomes. Future research should include analyses informed by the modified stress-vulnerability model, which serves as the theoretical foundations of IMR (
2,
43).
Regarding any effects on reduction of hospitalization, results were mixed. Two explanations seem plausible. Either IMR and ACT worked synergistically to reduce risk of hospitalization or ACT clinicians, either intentionally or unintentionally, chose to provide IMR to consumers with the least risk of rehospitalization. The low rates of hospitalization in the three RCTs suggest that well-stabilized outpatients were included, reducing the likelihood of finding reductions in hospital use. Also, no study has looked at the effects of IMR on reducing relapses or hospitalizations after a recent hospitalization, when people are more vulnerable to rehospitalization. In addition, the studies generally did not report on the effects of potential consumer-level variables—for example, illness severity, intellectual capability, and other services received—and agency-level variables—for example, climate and culture and client-to-staff ratio—that could moderate consumer outcomes.
Although implementation outcomes suggest that IMR can be successful, implementation success and acceptance merit further exploration. Dropout rates were generally consistent (between 20% and 30%) and were within the range found in studies of cognitive-behavioral therapy for psychosis (generally between 35% and 55%) (
44) and general outpatient services (
45). Extant studies did not examine predictors of dropout; studies generally have had little success at identifying consistent predictors of dropout among consumers. Completion rates varied more than dropout rates, with the lowest rates found in two studies of ACT teams. Because consumers receiving ACT experience severe illnesses, they may require a longer period to complete the IMR curriculum. Two related studies also found a lower hospitalization rate for the consumers receiving IMR, so it would be premature to determine that IMR is not useful for ACT consumers (
17,
18). It is also unclear to what extent socioeconomic factors, such as literacy and multiple role pressures, affect acceptability of IMR.
All studies that measured fidelity considered it acceptable, although Hasson-Ohayon and colleagues (
7) found low fidelity at some sites, which was also true at some sites in the NIEBP project. Low fidelity was found by studies that spanned across state lines and by one trial that was conducted in an inpatient setting. Geographical dispersion may be a limitation for consistently rigorous training and technical assistance.
Fidelity scores are lower for IMR than for some other practices, such as assertive community treatment and supported employment (
21,
23). Some authors have emphasized that the IMR fidelity scale relies heavily on clinical techniques, such as motivational, cognitive-behavioral, and educational teaching techniques (
21,
23). In contrast, fidelity scales for assertive community treatment, supported employment, and other programs are defined more in structural terms, such as team composition and location of services. Investigators have suggested that the difference in emphasis leads to lower fidelity ratings for IMR and other practices that rely on clinical techniques, such as integrated dual-disorder treatment and family psychoeducation (
21,
23).
Although fidelity is considered an important implementation outcome, the IMR fidelity scale has several limitations. Like most fidelity scales, it has had little psychometric validation and the cutoff for “implementation” was determined on the basis of expert opinion rather than empirical validation. In addition, the scale focuses on program-level fidelity, which does not take into account variation among clinicians in IMR competence. To this end, a group is currently validating an IMR competence tool—the IMR Treatment Integrity Scale (
46).
Implementation studies identified several important barriers and facilitators of IMR; however, methodologies preclude drawing conclusions regarding the effect of particular factors on specific implementation outcomes. The most consistent results were the importance of agency factors, in particular regular supervision, and contact with outside training and consultation. Future studies should examine the interplay between various implementation domains. It should also be noted that no study reported costs of implementation, an important practical consideration.
Conclusions
IMR was initially called an evidence-based practice on the basis of research on its components; research on IMR as a package is promising, indicating positive effects on consumers’ perceptions of recovery and illness management. Differences in the methodologies of outcomes studies make it impossible to draw firm conclusions regarding IMR’s effectiveness in comparison with other programs. As of yet, no population has emerged that does not generally benefit from the program, although little research has examined the relationship between consumer characteristics and response to IMR. More work is necessary to adapt IMR to special populations, such as persons who are involved with the criminal justice system.
IMR programs can be implemented with acceptable fidelity, but that may require substantial and comprehensive implementation support. Agency support, including supervision, and external consultation appear to be key facilitators of implementation. Future research should include active control groups, employ more psychometrically rigorous outcome measures, and examine key moderators of participation and outcomes.
