Outcomes for Implementation Research: Conceptual Distinctions, Measurement Challenges, and Research Agenda

Abstract: An unresolved issue in the field of implementation research is how to conceptualize and evaluate successful implementation. This paper advances the concept of “implementation outcomes” distinct from service system and clinical treatment outcomes. This paper proposes a heuristic, working “taxonomy” of eight conceptually distinct implementation outcomes—acceptability, adoption, appropriateness, feasibility, fidelity, implementation cost, penetration, and sustainability—along with their nominal definitions. We propose a two-pronged agenda for research on implementation outcomes. Conceptualizing and measuring implementation outcomes will advance understanding of implementation processes, enhance efficiency in implementation research, and pave the way for studies of the comparative effectiveness of implementation strategies.

Advancing a conceptual model of evidence-based practice implementation in public service sectors.

Abstract: Implementation science is a quickly growing discipline. Lessons learned from business and medical settings are being applied but it is unclear how well they translate to settings with different historical origins and customs (e.g., public mental health, social service, alcohol/drug sectors). The purpose of this paper is to propose a multi-level, four phase model of the implementation process (i.e., Exploration, Adoption/Preparation, Implementation, Sustainment), derived from extant literature, and apply it to public sector services. We highlight features of the model likely to be particularly important in each phase, while considering the outer and inner contexts (i.e., levels) of public sector service systems.

Mixed Method Designs in Implementation Research

Abstract: This paper describes the application of mixed method designs in implementation research in 22 mental health services research studies published in peer-reviewed journals over the last 5 years. Our analyses revealed 7 different structural arrangements of qualitative and quantitative methods, 5 different functions of mixed methods, and 3 different ways of linking quantitative and qualitative data together. Complexity of design was associated with number of aims or objectives, study context, and phase of implementation examined. The findings provide suggestions for the use of mixed method designs in implementation research.

Toward the Effective and Efficient Measurement of Implementation Fidelity

Abstract: Implementation science in mental health is informed by other academic disciplines and industries. Conceptual and methodological territory charted in psychotherapy research is pertinent to two elements of the conceptual model of implementation posited by Aarons and colleagues (2010)—implementation fidelity and innovation feedback systems. Key characteristics of scientifically validated fidelity instruments, and of the feasibility of their use in routine care, are presented. The challenges of ensuring fidelity measurement methods are both effective (scientifically validated) and efficient (feasible and useful in routine care) are identified as are examples of implementation research attempting to balance these attributes of fidelity measurement.

Developing the Mental Health Workforce: Review and Application of Training Approaches from Multiple Disciplines

Abstract: Strategies specifically designed to facilitate the training of mental health practitioners in evidence-based practices (EBPs) have lagged behind the development of the interventions themselves. The current paper draws from an interdisciplinary literature (including medical training, adult education, and teacher training) to identify useful training and support approaches as well as important conceptual frameworks that may be applied to training in mental health. Theory and research findings are reviewed, which highlight the importance of continued consultation/support following training workshops, congruence between the training content and practitioner experience, and focus on motivational issues. In addition, six individual approaches are presented with careful attention to their empirical foundations and potential applications. Common techniques are highlighted and applications and future directions for mental health workforce training and research are discussed.

Length of Stay of General Psychiatric Inpatients in the United States: Systematic Review

Abstract: Psychiatric length of stay (LOS) has reduced but is still longer than for physical disorders Inpatient costs are 16% of total mental health spending Regression analyses of the determinants of LOS for US adult psychiatric inpatients were systematically reviewed Most studies predated recent LOS reductions Psychosis, female gender and larger hospital size were associated with longer LOS, while discharge against medical advice, prospective payment, being married, being detained and either younger or middle age were associated with shorter LOS Associations appeared consistent, especially where sample size was above 3,000 Updated studies should be adequately powered and include the variables above

Training Research: Practical Recommendations for Maximum Impact

Abstract: This review offers practical recommendations regarding research on training in evidence-based practices for mental health and substance abuse treatment. When designing training research, we recommend: (a) aligning with the larger dissemination and implementation literature to consider contextual variables and clearly defining terminology, (b) critically examining the implicit assumptions underlying the stage model of psychotherapy development, (c) incorporating research methods from other disciplines that embrace the principles of formative evaluation and iterative review, and (d) thinking about how technology can be used to take training to scale throughout all stages of a training research project. An example demonstrates the implementation of these recommendations.

Knowledge of and Attitudes Towards Evidence-Based Practices in Community Child Mental Health Practitioners

Abstract: Research in the dissemination of evidence-based practices (EBPs) suggests that practitioners’ knowledge of and attitudes towards EBPs influence their decisions to adopt such practices. This study investigated the relationships between practitioner background variables and EBP knowledge and attitudes, as well as the relationship between knowledge and attitudes among public sector youth direct service providers (n = 240). Findings suggest that knowledge and attitudes relate to practitioners’ most advanced degree, practice setting, and licensure status. Additionally, lack of knowledge in the form of EBP under-identification was related to negative attitudes. Findings are discussed as they relate to the dissemination of EBPs.

Easier Said than Done: Intervention Sustainability in an Urban After-School Program

Abstract: Although sustainability is frequently described as a project goal in community-based programs, concentrated efforts to sustain interventions beyond the conclusion of research funding have only recently emerged as a focus of implementation research. The current paper describes a study of behavioral consultation to after-school program staff in low-SES, urban communities. Following consultation, staff use of four recommended tools and strategies was examined, emphasizing facilitators and barriers to sustainability. Results indicated high perceived utility and intention to use intervention components, but low sustainability at two follow-up time points within 1 year after the initial consultation concluded. Findings suggest that ongoing implementation support in community settings may be necessary to ensure the sustainability of interventions and meet the mental health needs of participating high-risk youth.

Design elements in implementation research: a structured review of child welfare and child mental health studies.

Abstract: Implementation science is an emerging field of research with considerable penetration in physical medicine and less in the fields of mental health and social services. There remains a lack of consensus on methodological approaches to the study of implementation processes and tests of implementation strategies. This paper addresses the need for methods development through a structured review that describes design elements in nine studies testing implementation strategies for evidence-based interventions addressing mental health problems of children in child welfare and child mental health settings. Randomized trial designs were dominant with considerable use of mixed method designs in the nine studies published since 2005. The findings are discussed in reference to the limitations of randomized designs in implementation science and the potential for use of alternative designs.

Characteristics of Anxious and Depressed Youth Seen in Two Different Clinical Contexts

Abstract: Previous research has revealed that youth seen at community clinics present with a higher frequency of externalizing problems and are demographically different from youth seen at research clinics. This study extends findings on these discrepancies by examining differences between youth at research and community clinics meeting criteria for two different primary disorders (anxiety and depression). Consistent with prior research, community clinic youth reported lower incomes, were more ethnically diverse, and had higher rates of externalizing problems compared to research clinic youth, regardless of primary diagnosis. Findings are discussed in terms of enhancing dissemination of evidence-based treatments for internalizing disorders in community settings.

The Role of Housing: A Comparison of Front-Line Provider Views in Housing First and Traditional Programs

Abstract: Purpose Within the mental health system, there are two distinct service models for adults who have severe mental illness and are homeless: one prioritizes treatment before accessing permanent housing (Treatment First) while the other provides permanent housing upfront followed by clinical support (Housing First). Investigating front-line providers working within these two models affords an opportunity to learn more about their implementation from an insider perspective, thus shedding light on whether actual practice is consistent with or contrary to these program models’ contrasting philosophical values.

Predictors of Treatment Attrition Among an Outpatient Clinic Sample of Youths With Clinically Significant Anxiety

Abstract: Predictors of treatment attrition were examined in a sample of 197 youths (ages 5–18) with clinically-significant symptoms of anxiety seeking psychotherapy services at a community-based outpatient mental health clinic (OMHC). Two related definitions of attrition were considered: (a) clinician-rated dropout (CR), and (b) CR dropout qualified by phase of treatment (pre, early, or late phases) (PT). Across both definitions, rates of attrition in the OMHC sample were higher than those for anxious youths treated in randomized controlled trials, and comorbid depression symptoms predicted dropout, with a higher rate of depressed youths dropping out later in treatment (after 6 sessions). Using the PT definition, minority status also predicted attrition, with more African-American youths lost pre-treatment. Other demographic (age, gender, single parent status) and clinical (externalizing symptoms, anxiety severity) characteristics were not significantly associated with attrition using either definition. Implications for services for anxious youths in public service settings are discussed. Results highlight the important role of comorbid depression in the treatment of anxious youth and the potential value of targeted retention efforts for ethnic minority families early in the treatment process.

Supporting Parents Who Have Youth with Emotional Disturbances Through a Parent-to-Parent Support Program: A Proof of Concept Study Using Random Assignment

Abstract: Poor outcomes for youth who have emotional disturbances (ED), especially for those youth who are placed in special education programs, are well documented. Parent Connectors is a parent-to-parent support program delivered through weekly telephone calls to families of youth with ED in special education programs, with the aim of increasing the engagement of parents in their child’s education and treatment and improving the academic and emotional functioning of the child. Findings from a proof of concept study using random assignment of participants yielded encouraging support for the clinical efficacy of the intervention. Results demonstrated enhanced outcomes for parents who were highly strained at the beginning of the study. Implications for future research in the area of parent support are provided.

Improvement in symptoms versus functioning: how do our best treatments measure up?

Abstract: We examined the effects of redefining standards of evidence for treatments targeting childhood mental health problems by expanding outcomes beyond symptom reduction to include functioning. Over 750 treatment protocols from 435 randomized controlled trials were rated based on empirical evidence. Nearly two-thirds (63.9%) demonstrated at least a minimum level of evidence for reducing symptoms; however, only 18.8% of treatments demonstrated evidence for reducing functional impairment. Of those treatments with empirical support for symptom reduction, the majority did not demonstrate empirical support for improvement in functioning because measures of functioning were not included in the studies in which these treatments were tested. However, even when measures of functioning were included, it was much more difficult for treatments to achieve improvement. Among treatments that achieved improvement in functioning, the most notable were Collaborative Problem Solving for disruptive behavior and Cognitive Behavioral Therapy plus Medication for traumatic stress because they demonstrated no support for symptom reduction but good support for improvement in functioning. Results are discussed within the context of evaluating the standards of evidence for treatments and the opportunity to move towards a multidimensional framework whose utility has the potential to exceed the sum of its parts.

Understanding clinicians' diagnostic practices: Attitudes toward the utility of diagnosis and standardized diagnostic tools

Abstract: Data on clinician diagnostic practices suggest they may not align with evidence-based guidelines. To better understand these practices, a multidisciplinary survey of 1,678 child clinicians examined attitudes toward the utility of diagnosis and standardized diagnostic tools. Psychiatrists were more likely than other disciplines to value diagnosis, whereas psychologists were more likely than others to value standardized diagnostic tools. Private practitioners held less positive views in both domains than other practitioners. Both attitude scales predicted self-reported diagnostic practices, although views of diagnosis utility were more associated with diagnosing in general, whereas views of diagnostic tools were more predictive of standardized tool use.

A comparison of treatment outcomes among chronically homelessness adults receiving comprehensive housing and health care services versus usual local care.

Abstract: Service use and 2-year treatment outcomes were compared between chronically homelessness clients receiving comprehensive housing and healthcare services through the federal Collaborative Initiative on Chronic Homelessness (CICH) program (n = 281) a sample of similarly chronically homeless individuals receiving usual care (n = 104) in the same 5 communities. CICH clients were housed an average of 23 of 90 days (52%) more than comparison group subjects averaging over all assessments over a 2-year follow-up period. CICH clients were significantly more likely to report having a usual mental health/substance abuse treater (55% vs. 23%) or a primary case manager (26% vs. 9%) and to receive community case management visits (64% vs. 14%). They reported receiving more outpatient visits for medical (2.3 vs. 1.7), mental health (2.8 vs. 1.0), substance abuse treatment (6.4 vs. 3.6), and all healthcare services (11.6 vs. 6.1) than comparison subjects. Total quarterly healthcare costs were significantly higher for CICH clients than comparison subjects ($4,544 vs. $3,326) due to increased use of outpatient mental health and substance abuse services. Although CICH clients were also more likely to receive public assistance income (80% vs. 75%), and to have a mental health/substance provider at all, they expressed slightly less satisfaction with their primary mental health/substance abuse provider (satisfaction score of 5.0 vs. 5.4). No significant differences were found between the groups on measures of substance use, community adjustment, or health status. These findings suggest that access to a well funded, comprehensive array of permanent housing, intensive case management, and healthcare services is associated with improved housing outcomes, but not substance use, health status or community adjustment outcomes, among chronically homeless adults.

Changes in psychotherapy utilization among consumers of services for major depressive disorder in the community mental health system.

Abstract: The goal of this investigation was to explore changes in psychotherapy utilization for patients with major depressive disorder (MDD) treated in community mental health agencies across two cohorts. We used a Medicaid claims database including approximately 300,000 public sector clients. Although the use of psychotherapy alone showed a small decrease, there was a large increase in the use of combined medication and psychotherapy as a treatment for MDD. Race was a significant predictor of both treatment type received and length of treatment. African American consumers were more likely to receive psychotherapy alone than combined treatment and attended significantly fewer psychotherapy sessions.

A Pilot Study Disseminating Cognitive Behavioral Therapy for Depression: Therapist Factors and Perceptions of Barriers to Implementation

Abstract: This preliminary report on dissemination of Cognitive Behavioral Therapy (CBT) for depression assessed numerous therapist factors thought to influence implementation in a community setting. Participants were 24 therapists, aged 26–61 who participated in three, 1-day workshops and 8 months of ongoing group consultation. Attitudes toward empirically supported treatments (ESTs) and readiness to change were positively correlated whereas attitudes toward ESTs were negatively correlated with perceived client barriers to implementation. Therapists’ report of client and setting factors were negatively associated with therapists’ reports of implementation of CBT. Results are discussed in terms of implications and recommendations for dissemination and implementation of ESTs.

Help-seeking for children with mental health problems: parents' efforts and experiences.

Abstract: Parents who contacted 1 of 15 children’s mental health agencies in Ontario, Canada reported on where and why they were seeking mental health services for their 4- to 17-year-old children. Parents contacted an average of four agencies (±1.7; range = 1–14) in the previous year. Approximately one-half of parents were looking for either multiple types of treatment, or help for different problems, across agencies. The complex pattern of help-seeking evidenced in our study likely increases the burden on the mental health care system and on families, and may reduce the likelihood that families will connect with the most appropriate treatment.

Therapist Training in Empirically Supported Treatments: A Review of Evaluation Methods for Short- and Long-Term Outcomes

Abstract: Therapist training efforts have been assessed using several outcomes. A model for evaluating therapist training in empirically supported treatments is presented, adapted from Kirkpatrick’s (in: Craig and Bittel (eds.) Training and development handbook, 1967) training evaluation model. The adapted framework includes short-term outcomes, such as reactions to training and changes in attitude, knowledge, or skills, and longer-term outcomes, such as changes in therapist behavior in practice or client outcomes. Evaluation methods for these outcomes are reviewed, with information on their validity, reliability, and feasibility. An agenda for further research to improve therapist training evaluation is presented, with discussion of how evaluation can inform other areas of the field.

The Science of Training in Evidence-Based Treatments in the Context of Implementation Programs: Current Status and Prospects for the Future

Abstract: Training plays a critical role within the broader implementation research agenda involving evidence-based treatments (EBTs). EBTs, interventions that have demonstrated client improvement within the context of controlled trials (Kazdin 2008), tend to be complex, multisession treatment packages that hinge largely on the provider’s execution of a set of interventions with a satisfactory level of fidelity (Carroll et al. 2010; Chorpita and Regan 2009; Herschell et al. 2010). Although training alone is not sufficient to guarantee successful implementation, there is evidence that adequate training can reduce variations in provider behavior, improve fidelity, and ultimately, increase the quality of service delivery (Aarons et al. 2011; Feldstein et al. 2008; Fixsen et al. 2005; Stirman et al. 2004) above and beyond that provided by therapy as usual (Schoener et al. 2006; Simons et al. 2010). In light of the central role training plays in the implementation of EBTs in mental health service delivery settings (Karlin et al. 2010; McHugh and Barlow 2010), efforts to scientifically examine the impact of training and to establish best practices in training are essential (Herschell et al. 2010). Our field is fortunate to be at the point at which EBTs have been designed, tested, and refined with much success; however, dissemination and implementation initiatives are still in their relative infancy (Becker et al. 2009). This early stage of evidence-based training development renders the field at a crossroads. One possible path parallels the traditional stage model of EBT development (Onken et al. 1997), with training methods developed and tested in university-based settings with tightly controlled conditions to demonstrate efficacy prior to testing effectiveness. As demonstrated by highly controlled studies of training (Miller et al. 2004; Sholomskas et al. 2005), this approach has merit inasmuch as information regarding necessary and sufficient training components, and optimal dosage, sequencing, and spacing of training can be identified (see Rakovshik and McManus 2010 for a review of these factors in the training of cognitive behavioral therapy). However, as the stage model of psychotherapy development has demonstrated, the needs of the field, in terms of understanding effective, efficient treatment strategies that can be deployed in less tightly controlled settings, easily outpace the stages of research (Institute of Medicine 2001). Similarly, given that advances in EBTs have outpaced the development of implementation supports (i.e., evidencebased training) (Fixsen et al. 2005), the ‘‘research-topractice gap’’ (McHugh and Barlow 2010) is at risk of continuing to widen, leaving a workforce with insufficient training and support in the very treatments that may have the best chance of improving the conditions of patients in need. An alternative path to promoting the science of training involves fitting the training program into the existing mental health delivery system (Stirman et al. 2010) to K. D.

Investigating the relationship between neighborhood experiences and psychiatric distress for individuals with serious mental illness.

Abstract: The present study examined the relationships between how research participants experienced their neighborhood, their neighborhood social climate, and psychological well-being. Participants (n = 525) were residents of supported housing programs who used mental health services at one of 17 community mental health centers in South Carolina. Hierarchical regression and mediation analyses were employed to answer research questions. Results suggest that neighbor relations, perceptions of neighborhood safety, and neighborhood satisfaction were significantly associated with perceptions of neighborhood social climate; and neighborhood social climate accounted for a significant amount of the variance in psychiatric distress. Of particular interest, perceptions of neighborhood social climate fully mediated the relationship between the specific reported neighborhood experiences and psychiatric distress. These findings have implications for interventions and policy aimed at promoting integration of individuals with serious mental illness into community settings.

Relationship Between Satisfaction, Patient-Centered Care, Adherence and Outcomes Among Patients in A Collaborative Care Trial for Depression

Abstract: Collaborative care is known to improve satisfaction, patient-centered care, adherence, and depression symptom severity. However, associations among these outcomes have not been examined. Outcomes were measured at 6 months for 360 primary care patients with depression enrolled in a randomized trial of collaborative care. Main effects and mediation effects were examined using logistic regression analyses. Collaborative care significantly improved both satisfaction and patient-centered care. Patient-centered care did not mediate the positive effect that collaborative care had on satisfaction. Improvements in symptom severity partially mediated collaborative care’s effect on satisfaction. Satisfaction did not mediate collaborative care’s positive effect on antidepressant adherence.

Training Addiction Counselors to Implement CBT for Depression

Abstract: Many clients in publicly funded substance abuse treatment programs suffer from depression yet lack access to effective mental health treatment. This study sought to examine whether addiction counselors could be effectively trained to deliver group CBT for depression and to ascertain client perceptions of the treatment. Five counselors were trained in the therapy and treated 113 clients with depression symptoms. Counselors demonstrated high fidelity to the therapy and client perceptions of the therapy were positive. Our results suggest that training addiction counselors to deliver group CBT for depression is a promising integrated treatment approach for co-occurring depression and substance disorders.

Effects of workshop training for providers under mandated use of an evidence-based practice.

Abstract: Workshops are a common strategy for fostering the adoption of evidence-based practices (EBP), but workshops alone may not change provider behavior. This study investigates the impact of a two-day training combined with an existing mandate for EBP use. Providers attending regional workshops showed improved attitudes toward the behavioral parent training model, but not EBPs in general. Participants were more accepting of behavioral techniques shortly after training, but the effect was not maintained. Examination of youth served prior to and after the training showed that providers increased their use of the EBP but overall outcomes were not improved.

The Work of Recovery on Two Assertive Community Treatment Teams

Abstract: The compatibility of recovery work with the Assertive Community Treatment (ACT) model has been debated; and little is known about how to best measure the work of recovery. Two ACT teams with high and low recovery orientation were identified by expert consensus and compared on a number of dimensions. Using an interpretive, qualitative approach to analyze interview and observation data, teams differed in the extent to which the environment, team structure, staff attitudes, and processes of working with consumers supported principles of recovery orientation. We present a model of recovery work and discuss implications for research and practice.

A comprehensive model for mental health tobacco recovery in new jersey.

Abstract: Despite the high prevalence of tobacco use, disproportionate tobacco consumption, and excess morbidity and mortality, smokers with mental illness have reduced access to tobacco dependence treatment across the health care spectrum. We have developed a comprehensive model for Mental Health Tobacco Recovery in New Jersey (MHTR-NJ) that has the overarching goal of improving tobacco cessation for smokers with serious mental illness. Important steps involve engaging patients, professionals and the community to increase understanding that addressing tobacco use is important. In addition to increasing demand for tobacco treatment services, we must educate mental health professionals in evidence-based treatments so that patients can seek help in their usual behavioral health care setting. Peer services that offer hope and support to smokers are essential. Each of the policy or cessation initiatives described address the two core goals of this model: to increase demand for tobacco cessation services for mentally ill smokers and to help more smokers with mental illness to quit. Each has been pilot tested for feasibility and/or effectiveness and revised with feedback from stakeholders. In this way this implementation model has brought together academics, clinicians, administrators and mental health consumers to develop tobacco programming and policy that has been tested in a real world environment and serves as a model for other states.

Medication adherence, ethnicity, and the influence of multiple psychosocial and financial barriers.

Abstract: Medication adherence is critical for patients with bipolar disorder to avoid symptom exacerbation and diminished quality of life. Most analyses consider adherence barriers individually rather than conjointly, while neglecting potential ethnic differences. 435 patients in the Continuous Improvement for Veterans in Care––Mood Disorders study reported multiple financial and psychosocial factors influencing adherence. Logistic regression modeled adherence as a function of perceived barriers, including cost burden, access, binge drinking, poor therapeutic alliance, and medication beliefs. Nearly half the cohort experienced adherence difficulty, averaging 2.8 barriers, with minority veterans reporting lower adherence than white patients, particularly financial burden and treatment access. Total barriers were significantly associated with worse adherence (OR = 1.24 per barrier), notably poor medication beliefs, binge drinking, and difficulty accessing psychiatric specialists (ORs of 2.41, 1.95 and 1.73, respectively). Veterans with bipolar disorder experience numerous adherence barriers, with certain obstacles proving especially pernicious. Fortunately tailored clinical interventions can improve adherence, particularly by addressing modifiable risk factors.

Patient and Program Predictors of 12-Month Outcomes for Homeless Veterans Following Discharge from Time-Limited Residential Treatment

Abstract: The U.S. Department of Veterans Affairs provides transitional residential treatment to homeless veterans through three types of programs: VA-staffed Domiciliary care, and two types of community-based treatment (one funded through locally managed contracts and the other through national grants). This study compared treatment process and outcomes in these three programs and also sought to identify differences in outcome between dually diagnosed veterans, veterans with substance abuse problems or psychiatric problems alone, and those with no psychiatric diagnoses. Altogether, 1,338 veterans admitted to the 3 types of program were recruited to participate in a prospective naturalistic study which evaluated housing, clinical and community adjustment outcomes during the year following discharge. Data on 1,003 veterans for whom psychiatric diagnostic, social climate and length of stay data were available were used to compare participants in the three program types at baseline. Regression models were used to compare outcomes across program and diagnostic types net of baseline differences between study participants, and of differences in social climate and length of stay. The overall follow-up rate across all time points was 72%. Significant differences across programs were observed on only 2 baseline measures as well as on several baseline values of the outcome measures, length of stay and a measure of social climate. Adjusting for veteran baseline differences alone there were no differences in outcomes by program after correction for multiple comparisons. Dually diagnosed veterans had poorer mental health and overall quality of life outcomes. Longer length of stay and more positive social climate were associated with superior outcomes on several measures. The adjusted mean estimate of the proportion of veterans housed at 12 months follow-up was 78%, similar to published outcomes for supported housing. Length of stay, rather than program funding configuration or diagnostic group, was the strongest predictor of outcomes in time-limited residential treatment programs in which 1-year housing was similar to those in direct-placement supported housing programs.
