BackgroundDespite a solid research base supporting evidence-based practices (EBPs) for addiction treatment such as contingency management and medication-assisted treatment, these services are rarely implemented and delivered in community-based addiction treatment programs in the USA. As a result, many clients do not benefit from the most current and efficacious treatments, resulting in reduced quality of care and compromised treatment outcomes. Previous research indicates that addiction program leaders play a key role in supporting EBP adoption and use. The present study expanded on this previous work to identify strategies that addiction treatment program leaders report using to implement new practices.MethodsWe relied on a staged and iterative mixed-methods approach to achieve the following four goals: (a) collect data using focus groups and semistructured interviews and conduct analyses to identify implicit managerial strategies for implementation, (b) use surveys to quantitatively rank strategy effectiveness, (c) determine how strategies fit with existing theories of organizational management and change, and (d) use a consensus group to corroborate and expand on the results of the previous three stages. Each goal corresponded to a methodological phase, which included data collection and analytic approaches to identify and evaluate leadership interventions that facilitate EBP implementation in community-based addiction treatment programs.ResultsFindings show that the top-ranked strategies involved the recruitment and selection of staff members receptive to change, offering support and requesting feedback during the implementation process, and offering in vivo and hands-on training. Most strategies corresponded to emergent implementation leadership approaches that also utilize principles of transformational and transactional leadership styles. Leadership behaviors represented orientations such as being proactive to respond to implementation needs, supportive to assist staff members during the uptake of new practices, knowledgeable to properly guide the implementation process, and perseverant to address ongoing barriers that are likely to stall implementation efforts.ConclusionsThese findings emphasize how leadership approaches are leveraged to facilitate the implementation and delivery of EBPs in publicly funded addiction treatment programs. Findings have implications for the content and structure of leadership interventions needed in community-based addiction treatment programs and the development of leadership interventions in these and other service settings.

OBJECTIVE The general medical health of individuals with serious mental illnesses is compromised relative to those without serious mental illnesses. To address this health disparity, numerous integrated care strategies are being employed from the system level to the level of individual patients. However, self-management of health care, a strategy considered an integral aspect of typical care, has been infrequently included in interventions for this population. Despite reservations about the capacity of those with serious mental illnesses to self-manage health care, a subset of new interventions focused on general medical health in this population has tested whether models including self-management strategies have empirical support. To understand whether these models are supported, the authors reviewed the evidence for self-management models. METHODS This systematic review examined collaborative and integrated care models that include self-management components for individuals with serious mental illnesses. RESULTS Across the 14 studies identified in this review, promising evidence was found that individuals with serious mental health issues can collaborate with health professionals or be trained to self-manage their health and health care. The evidence supports the use of mental health peers or professional staff to implement health care interventions. However, the substantial heterogeneity in study design, types of training, and examined outcomes limited conclusions about the comparative effectiveness of existing studies. CONCLUSIONS This review found preliminary support that self-management interventions targeting the general medical health of those with serious mental illnesses are efficacious, but future work is needed to determine what elements of training or skills lead to the most salient changes.

The use of evidence-based practices (EBPs) is associated with favorable client outcomes, yet perceived burden of using EBPs may affect the adoption and implementation of such practices. Multilevel path analysis was used to examine the associations of transformational leadership with organizational climate, and their associations with perceived burden of using EBPs. Results indicated significant relationships between transformational leadership and empowering and demoralizing climates, and between demoralizing climate and perceived burden of EBPs. We found significant indirect associations of leadership and perceived burden through organizational climate. Findings suggest that further research is needed to examine the extent to which improving leadership and organizational climate may reduce perceived burden and use of EBPs with the ultimate goal of enhancing quality of care.

BackgroundMembers of racial and ethnic minority groups are most likely to experience limited access and poor engagement in addiction treatment. Research has been limited on the role of program capacity and delivery of comprehensive care in improving access and retention among minorities with drug abuse issues. The goal of this study was to examine the extent to which access and retention are enhanced when racial and ethnic minorities receive care from high-capacity addiction health services (AHS) programs and via coordination with mental health and receipt of HIV testing services.MethodsThis multilevel cross-sectional analysis involved data from 108 programs merged with client data from 2011 for 13,478 adults entering AHS. Multilevel negative binomial regression models were used to test interactions and indirect relationships between program capacity and days to enter treatment (wait time) and days in treatment (retention).ResultsCompared to low-capacity programs and non-Latino and non-African American clients, Latinos and African Americans served in high-capacity programs reported shorter wait times to admission, as hypothesized. African Americans also had longer treatment retention in high-capacity programs. Receipt of HIV testing and program coordination of mental health services played an indirect role in the relationship between program capacity and wait time.ConclusionsProgram capacity and coordinated services in AHS may reduce disparities in access to care. Implications for supporting low-capacity programs to eliminate the disparity gap in access to care are discussed.

Despite the effectiveness of exposure-based cognitive behavioral therapy (CBT) for anxiety disorders, few individuals in need receive this treatment, particularly in community mental health settings serving low-income adults. The present study took a preliminary step to understand these barriers by conducting a series of key informant interviews and focus groups among patients, providers, clinical administrators, and policy makers. Several themes emerged as barriers to the delivery of exposure-based CBT in these settings, including therapist training and compentency issues, logistical issues, and funding stream issues. Clinical implications and future research that can build from these data are discussed.

CBT is considered the first-line treatment for anxiety disorders, particularly when it involves gradual confrontation with feared stimuli (i.e., exposure); however, delivery of CBT for anxiety disorders in real-world community clinics is lacking. This study utilized surveys we developed with key stakeholder feedback (patient, provider, and administrator) to assess patient and provider/administrator perceptions of the barriers to delivering (or receiving) CBT for anxiety disorders. Providers/administrators from two counties in California (N = 106) indicated lack of training/competency as primary barriers. Patients in one large county (N = 42) reported their own symptoms most often impacted treatment receipt. Both groups endorsed acceptability of exposure but indicated that its use in treatment provided/received had been limited. Implications and recommendations are discussed.

Advancing theory development: exploring the leadership–climate relationship as a mechanism of the implementation of cultural competence

Erick G. Guerrero; Karissa Fenwick; Yinfei Kong

BackgroundLeadership style and specific organizational climates have emerged as critical mechanisms to implement targeted practices in organizations. Drawing from relevant theories, we propose that climate for implementation of cultural competence reflects how transformational leadership may enhance the organizational implementation of culturally responsive practices in health care organizations.MethodsUsing multilevel data from 427 employees embedded in 112 addiction treatment programs collected in 2013, confirmatory factor analysis showed adequate fit statistics for our measure of climate for implementation of cultural competence (Cronbach’s alpha = .88) and three outcomes: knowledge (Cronbach’s alpha = .88), services (Cronbach’s alpha = .86), and personnel (Cronbach’s alpha = .86) practices.ResultsResults from multilevel path analyses indicate a positive relationship between employee perceptions of transformational leadership and climate for implementation of cultural competence (standardized indirect effect = .057, bootstrap p < .001). We also found a positive indirect effect between transformational leadership and each of the culturally competent practices: knowledge (standardized indirect effect = .006, bootstrap p = .004), services (standardized indirect effect = .019, bootstrap p < .001), and personnel (standardized indirect effect = .014, bootstrap p = .005).ConclusionsFindings contribute to implementation science. They build on leadership theory and offer evidence of the mediating role of climate in the implementation of cultural competence in addiction health service organizations.

‘It’s Like You Do It Without Knowing That You’re Doing It’: Practitioner Experiences with ACT Implementation

Rebecca Lengnick-Hall; Karissa Fenwick; Benjamin F. Henwood

Using a case study approach, this study explores the experiences of providers at three organizations identified by county mental health executives as exemplar programs that have received continued and competitive funding to deliver assertive community treatment (ACT) in a large urban county in California. Interviews were conducted with 37 participants including program directors (n = 4), frontline staff (n = 31), and county mental health executives (n = 2). Frontline provider perspectives reveal that, in many ways, teams appear to be working within an ACT model in the absence of detailed explicit knowledge about ACT’s core components, frequent or in-depth conversations about ACT, or awareness of fidelity monitoring. Integration of program director and county executive perspectives illustrates how inner and outer contextual information can explain these on-the-ground ACT implementation experiences. This study illustrates the nuanced ways that frontline staff might understand and define evidence-based practice (EBP) use and has implications for studying EBP implementation.

Sources of Social Support After Patient Assault as Related to Staff Well-Being

Erin L. Kelly; Karissa Fenwick; John S. Brekke; Raymond W. Novaco

Patient assault is a serious issue for the well-being of staff in psychiatric hospitals. To guide workplace responses to patient assault, more information is needed about social support from different sources and whether those supports are associated with staff well-being. The present study examines social support after patient assault from work-based and nonwork-based sources, and whether inpatient psychiatric staff desires support from them and perceive the support received as being effective. Received support across sources was examined in relations to staff well-being (physical health, mental health, anger, sleep quality) and perceptions of safety. Survey data was collected from 348 clinical staff in a large public forensic mental hospital. Among the 242 staff who reported an assault in the last year, 71% wanted support and 72% found effective support from at least one source. Generally, effective support from supervisors, coworkers, and their combination was associated with better well-being. Support from nonwork sources was related to less concerns about safety, but not to other well-being measures. However, 28% of staff did not receive effective support from any source postassault. Gaps in support as reported in this study and as found by other investigators call for systematic programming by hospital organizations to enhance the well-being of clinical staff, which in turn has implications for patient care.

Implementation of comprehensive services as a mediator and race and ethnicity as a moderator of access and retention in addiction health services

Erick G. Guerrero; Karissa Fenwick; Christine E. Grella; Thomas D'Aunno

Background Increasing evidence has suggested that well-resourced programs are more likely than low-resourced programs to deliver comprehensive care to individuals with cooccurring conditions and achieve greater client access and retention. But there is limited understanding of the service delivery process that allows high-capacity programs to reduce their wait times for treatment entry and their rates of dropout. Purpose
