Implementation and Mental Health Outcomes of a Service Cascade Linking Child Welfare and Children's Mental Health Systems: A Case Study of the Gateway CALL Demonstration.

The mental health needs of children and youth involved in the child welfare system remain largely unmet. Service cascades are an emerging approach to systematizing mental health screening, assessment, and treatment referral processes. However, evidence is minimal and inconsistent regarding the effectiveness of such approaches for improving mental health service access and outcomes. In an effort to address this gap, this study presents a case-study of the implementation fidelity and treatment outcomes of the Gateway CALL service cascade. Study analyses involved longitudinal data collected as part of a larger evaluation of Gateway CALL. Specifically, descriptive and linear mixed model analyses were conducted to assess the implementation of service cascade components, and changes in mental health outcomes (behavior problems) among 175 children placed out-of-home during the study. Study analyses found that although fidelity was strong early in the service cascade, implementation began to break down once components involved more than one service system (child welfare, mental health). However, results also indicated that parent-reported child behavior problems decreased significantly over time, despite later cascade components being implemented with poor fidelity to the Gateway CALL service model. For children and youth involved in child welfare systems, service cascades like Gateway CALL have the potential to significantly improve both mental health service receipt and outcomes. To maximize the effectiveness of such approaches, later phases of implementation may require increased attention and support, particularly regarding processes and outcomes that cross child welfare and mental health service systems.

Implementing Intergenerational Best Practices in Community-Based Settings: A Preliminary Study.

Evidence-based intergenerational (IG) programs bring youth and older adults together in shared activities and promote socioemotional health across age-groups. The core components of these IG programs include 14 IG "best practices" that should be implemented during IG program sessions to optimize program effectiveness for both youth and older adult participants. Despite the proliferation of IG programs across the United States, it is unclear the extent to which these IG best practices have been implemented in the community. This preliminary study assesses the implementation of IG best practices at two community-based sites by program leaders who participated in a multifaceted professional education intervention for IG best practice use. Implementation of best practices was measured through the Best Practices Checklist completed by program leaders and trained coders as well as through narrative written comments. Program leaders indicated that they were able to consistently implement six out of the 14 IG best practices in 46 IG sessions, whereas the best practice named "Adaptations to equipment were made" was least likely to be implemented. Analysis of narrative comments indicated that (a) the group arrangement of participants and (b) program leaders' familiarity with activities also influenced implementation. While many IG best practices can be implemented in the community, some best practices can be implemented with greater ease and consistency. Training resources can support IG best practice implementation; however, our multifaceted professional education intervention may benefit from the addition of case examples or vignettes to depict potential strategies for optimizing evidence-based IG practices.

Housing First Combined with Suicide Treatment Education and Prevention (HOME + STEP): study protocol for a randomized controlled trial.

BACKGROUND: Youth experiencing homelessness are at high risk for suicide, yet few studies have evaluated risk reduction interventions targeting suicidal ideation in this vulnerable population. A comprehensive approach to risk-reduction is needed that addresses basic needs and provides targeted interventions for those at highest risk. The protocol described builds on the design of the first randomized trial of Housing First (HF) for homeless youth. The primary objective is to determine whether housing combined with supportive services that include suicide screening and targeted psychotherapy (Cognitive Therapy for Suicide Prevention) is effective for reducing suicidal ideation and other secondary outcomes (depression and suicide attempts). Additionally, we will explore mediators of the treatment effect (housing stability and substance use) and determinants of implementation. METHODS: Youth recruited to the HF trial will be randomized to HF + supportive services (n = 120), or supportive services alone (n = 120). The "Suicide Treatment Education and Prevention" (STEP) protocol will additionally screen youth in both arms at baseline and 3 months for suicidal ideation (SSI-W). Those who screen as moderate risk for suicide (SSI-W ≥ 10) will be offered CTSP, which includes up to 9 sessions over the first 6 months following enrollment. CTSP will be delivered in one-on-one sessions by a trained advocate. Research assessments will be collected to assess outcomes (including suicidal ideation) at baseline, 3, 6, 9 and 12 months. Qualitative interviews with subjects receiving CTSP and other stakeholders will explore implementation determinants. DISCUSSION: The study will fill an important gap in the literature about the added benefit of HF combined with supportive services including suicide screening and treatment for reducing suicidal ideation in homeless youth. With the urgent need to address both homelessness and suicide risk, evidence is needed about services that can be integrated into delivery settings for youth experiencing homelessness.

Competition Among Mental Health Organizations: Environmental Drivers and Strategic Responses.

While mental health system reforms have sought to leverage competition in the private sector to improve service quality and costs, competition among mental health organizations is poorly understood. To inform future studies about the impact of policy and system reforms on mental health organizations and service delivery, this qualitative study explores (1) resources for which organizations compete most intensively, (2) drivers of competition, and (3) leaders' strategic organizational responses. Semi-structured phone interviews were conducted with 15 organizational leaders (CEO's, executive directors) representing about 22% of organizations in the regional mental health market. Interviews covered leaders' perceptions about competition, and their strategic responses. Porter's seminal framework on competition was used to interpret codes and themes. Intensive competition for personnel was driven by workforce shortages, new for-profit organizations, and alternative employment opportunities. In response, organizations have attended to wages/benefits, recruitment, and retention. However, strong community need, expanded insurance coverage, and a history of local strategic responses that created service niches appeared to have minimized competition for financial resources in the region. Competition for funding and clients was expected to intensify under systems reform, and in anticipation, organizations were expanding services. Leaders also feared for the viability of smaller organizations in highly competitive environments. Consistent with theory on competition, mental health organizations compete and respond in ways that might improve services. However, the goals of privatization may have been unrealized because of minimal competition for funding and clients, and intense competition may undermine quality.

How Do Peers Shape Mental Health Clinicians' Attitudes Toward New Treatments?

Through everyday interactions, mental health clinicians are exposed to their colleagues' views toward new treatments, which can influence clinicians' own attitudes and implementation especially in high-stress environments. This study examines how exposure to peers' attitudes in the workplace through three common workplace interactions (advice sharing, discussion, and friendship) shapes clinicians' (n = 163) own attitudes toward measurement-based care (MBC). Clinicians tended to have more positive attitudes toward MBC with greater exposure to peers with positive attitudes through advice-sharing and informal workplace discussions, but not through friendships. Results highlight the importance of strong workplace relationships for implementation.

Evaluating the Implementation of Fall Risk Management Practices within Home-delivered Meal Organizations.

Falls remain a major public health issue, particularly for frail older adults, such as those who receive home-delivered meals (HDMs). Social workers who assess the needs of HDM clients and routinely monitor their care are uniquely positioned to address fall prevention; however, the degree to which HDM social workers currently manage fall risk is unknown. To close this knowledge gap, we conducted a retrospective chart review and evaluated HDM social workers' current practices relative to identifying clients at risk for falling and the client characteristics associated with social workers' perceptions of fall risk. A total of 230 client charts were included in our analysis. Thirty-eight percent of HDM clients were determined to be at risk of falling. Advanced age, activity limitations, and specific health conditions (e.g., diabetes mellitus) were associated with social workers' fall risk concerns. However, over 80% of our sample presented with well-established fall risk factors (e.g., mobility impairment) suggesting that HDM social workers might be under-identifying fall-risks. Though HDM social workers are well positioned to play a critical role in fall risk management, systematic efforts are needed to optimize social workers' capacity for effectively identifying HDM clients at risk for falling.

Skills for Developing and Maintaining Community-Partnerships for Dissemination and Implementation Research in Children's Behavioral Health: Implications for Research Infrastructure and Training of Early Career Investigators.

By engaging with community partners, dissemination and implementation scholars can enhance research relevance and translation. We illustrate the skills needed for developing and maintaining community partnerships by presenting two case studies of partnerships between early-career investigators and child welfare systems to implement mental health interventions. The cases represent two models of partnership (investigator-led and agency-led), highlighting the value and difficulty of conducting community-engaged implementation research. The experiences described feature strategies for building and managing relationships, navigating rules and regulations, adaptation, and securing resources. We offer suggestions for improving training and research infrastructures to support community-engaged implementation scholars.

Do learning collaboratives strengthen communication? A comparison of organizational team communication networks over time.

BACKGROUND: Collaborative learning models were designed to support quality improvements, such as innovation implementation by promoting communication within organizational teams. Yet the effect of collaborative learning approaches on organizational team communication during implementation is untested. PURPOSE: The aim of this study was to explore change in communication patterns within teams from children's mental health organizations during a year-long learning collaborative focused on implementing a new treatment. We adopt a social network perspective to examine intraorganizational communication within each team and assess change in (a) the frequency of communication among team members, (b) communication across organizational hierarchies, and (c) the overall structure of team communication networks. METHODOLOGY/APPROACH: A pretest-posttest design compared communication among 135 participants from 21 organizational teams at the start and end of a learning collaborative. At both time points, participants were asked to list the members of their team and rate the frequency of communication with each along a 7-point Likert scale. Several individual, pair-wise, and team level communication network metrics were calculated and compared over time. FINDINGS: At the individual level, participants reported communicating with more team members by the end of the learning collaborative. Cross-hierarchical communication did not change. At the team level, these changes manifested differently depending on team size. In large teams, communication frequency increased, and networks grew denser and slightly less centralized. In small teams, communication frequency declined, growing more sparse and centralized. PRACTICE IMPLICATIONS: Results suggest that team communication patterns change minimally but evolve differently depending on size. Learning collaboratives may be more helpful for enhancing communication among larger teams; thus, managers might consider selecting and sending larger staff teams to learning collaboratives. This study highlights key future research directions that can disentangle the relationship between learning collaboratives and team networks.

Tracking implementation strategies: a description of a practical approach and early findings.

BACKGROUND: Published descriptions of implementation strategies often lack precision and consistency, limiting replicability and slowing accumulation of knowledge. Recent publication guidelines for implementation strategies call for improved description of the activities, dose, rationale and expected outcome(s) of strategies. However, capturing implementation strategies with this level of detail can be challenging, as responsibility for implementation is often diffuse and strategies may be flexibly applied as barriers and challenges emerge. We describe and demonstrate the development and application of a practical approach to identifying implementation strategies used in research and practice that could be used to guide their description and specification. METHODS: An approach to tracking implementation strategies using activity logs completed by project personnel was developed to facilitate identification of discrete strategies. This approach was piloted in the context of a multi-component project to improve children's access to behavioural health services in a county-based child welfare agency. Key project personnel completed monthly activity logs that gathered data on strategies used over 17 months. Logs collected information about implementation activities, intent, duration and individuals involved. Using a consensus approach, two sets of coders categorised each activity based upon Powell et al.'s (Med Care Res Rev 69:123-57, 2012) taxonomy of implementation strategies. RESULTS: Participants reported on 473 activities, which represent 45 unique strategies. Initial implementation was characterised by planning strategies followed by educational strategies. After project launch, quality management strategies predominated, suggesting a progression of implementation over time. Together, these strategies accounted for 1594 person-hours, many of which were reported by the leadership team that was responsible for project design, implementation and oversight. CONCLUSIONS: This approach allows for identifying discrete implementation strategies used over time, estimating dose, describing temporal ordering of implementation strategies, and pinpointing the major implementation actors. This detail could facilitate clear reporting of a full range of implementation strategies, including those that may be less observable. This approach could lead to a more nuanced understanding of what it takes to implement different innovations, the types of strategies that are most useful during specific phases of implementation, and how implementation strategies need to be adaptively applied throughout the course of a given initiative.

"They make money off of us": a phenomenological analysis of consumer perceptions of corruption in Kenya's HIV response system.

BACKGROUND: Problems with misallocation and redirection of critical resources and benefits intended for PLHIV are not uncommon in Kenya. This study explores corruption in Kenya's HIV response system and the implications for health outcomes from the perspective of people living with HIV (PLHIV). Although they might not be directly responsible for health care fund management, PLHIV and their advocacy efforts have been central to the development of HIV system response and they have a vested interest in ensuring proper governance. METHODS: This phenomenological study was conducted in 2012 in Kiambu County in Kenya. The study was designed to capture the experiences of a select group of individuals living with HIV and AIDS and subsequent effects on intergenerational wealth transmission. Four focus groups were conducted with self-convened HIV/AIDS peer support groups. Findings related to corruption emerged unexpectedly, albeit consistently, across all four focus groups. To validate core themes within the data, including corruption, two coders independently reviewed and coded the data. RESULTS: Participants described incidences of resource misallocation, theft, and denial of services across three thematic levels namely at the interpersonal, provider, and institutional levels. Participants described the negative influence of corruption on their health and financial well-being, and propose: (1) strengthening legal protections for assets belonging to PLHIV, (2) direct representation of PLHIV within service agencies, (3) and addressing information asymmetries to inject transparency into the response system. CONCLUSION: Our findings add to the growing literature that identifies advocacy among individuals and families impacted by HIV and AIDS to be a useful tool in drawing attention to harmful practices in the HIV response infrastructure; consistent with this movement, communities in Kenya demand greater control over programmatic interventions both at the national and local levels.

Constraints and Benefits of Child Welfare Contracts with Behavioral Health Providers: Conditions that Shape Service Access.

This qualitative study examines worker perceptions of how public child welfare agencies' purchase of service contracts with private behavioral health organizations can both facilitate and constrain referral making and children's access to services. Five, 90-min focus groups were conducted with workers (n = 50) from an urban public child welfare agency in the Midwest. Using a modified grounded theory approach, findings suggest that contracts may expedite service linkages, but contract benefits are conditioned upon design and implementation. Results also suggest the critical role of front line workers in carrying out contractual relationships. Implications for research and interventions for enhancing contracting are discussed.

Can Learning Collaboratives Support Implementation by Rewiring Professional Networks?

This study examined how a learning collaborative focusing on trauma-focused CBT (TF-CBT) impacted advice-seeking patterns between clinicians and three key learning sources: (1) training experts who share technical knowledge about TF-CBT, (2) peers from other participating organizations who share their implementation experiences, and (3) colleagues from their own agency who provide social and professional support. Based on surveys administered to 132 clinicians from 32 agencies, participants' professional networks changed slightly over time by forming new advice-seeking relationships with training experts. While small, these changes at the clinician-level yielded substantial changes in the structure of the regional advice network.

Coordinating nonprofit children's behavioral health services: clique composition and relationships.

BACKGROUND: Why organizational cliques are associated with better performance in service delivery networks has yet to be explained. Certain properties of cliques may account for improved performance including the composition of clique members and the quality of their relationships. PURPOSE: The aim of this study is to offer insight into how organizations working through cliques improve network performance by exploring the complementarity of services provided by clique members and testing two hypotheses about trust and perceived benefits among clique members. METHODOLOGY: Survey and archival data were collected from a regional network of 36 nonprofit children's mental health agencies that belong to a coalition. First, clique analyses and network visualization were used to identify cohesive subgroups. Second, the complementarity of services provided by the groups was explored by calculating scores for each group to reflect the level of differentiation in services and client population as reported in archival data. Third, ANOVA density models were used to test whether clique relationships are characterized by higher perceived trust and benefits compared with nonclique member relationships. FINDINGS: Three groups were identified. These groups provide complementary services to similar client populations. Trust within all three cliques was higher than nonclique member relationships. Members of all three cliques perceived greater efficiency, and two of the three cliques also perceived greater access to care and service quality. PRACTICE IMPLICATIONS: Results support selecting clique partners based on service mix. To gain organizational benefits and improve network performance, partners should offer distinct services relative to one another but to similar clients.

An empirical typology of private child and family serving agencies.

Differences in how services are organized and delivered can contribute significantly to variation in outcomes experienced by children and families. However, few comparative studies identify the strengths and limitations of alternative delivery system configurations. The current study provides the first empirical typology of private agencies involved with the formal child welfare system. Data collected in 2011 from a national sample of private agencies were used to classify agencies into five distinct groups based on internal management capacity, service diversification, integration, and policy advocacy. Findings reveal considerable heterogeneity in the population of private child and family serving agencies. Cross-group comparisons suggest that differences in agencies' strategic and structural characteristics correlated with agency directors' perceptions of different pressures in their external environment. Future research can use this typology to better understand local service systems and the extent to which different agency strategies affect performance and other outcomes. Such information has implications for public agency contracting decisions and could inform system-level assessment and planning of services for children and families.

Collaboration, Competition, and Co-opetition: Interorganizational Dynamics Between Private Child Welfare Agencies and Child Serving Sectors.

Human service agencies are encouraged to collaborate with other public and private agencies in providing services to children and families. However, they also often compete with these same partners for funding, qualified staff, and clientele. Although little is known about complex interagency dynamics of competition and collaboration in the child-serving sector, evidence suggests that competition can undermine collaboration unless managed strategically. This study explores the interrelationship between competition and collaboration, sometimes referred to as "co-opetition." Using a national dataset of private child and family serving agencies, we examine their relationships with other child serving sectors (N=4460 pair-wise relationships), and explore how variations in patterns of collaboration and competition are associated with several organizational, environmental and relational factors. Results suggest that most relationships between private child welfare agencies and other child serving agencies are characterized by both competition and collaboration (i.e. "co-opetition"), and is most frequently reported with other local private child welfare agencies. Logistic regression analyses indicate that co-opetition is likely to occur when private child welfare agencies have a good perceived relationship or a sub-contract with their partner. Findings have implications for how agency leaders manage partner relationships, and how public child welfare administrators structure contracts.

Assessing perspectives on an intervention connecting adolescents in outpatient psychiatry care to contraceptive counseling in the United States.

BACKGROUND: Adolescents with psychiatric disorders have high rates of unintended pregnancy and experience barriers to accessing sexual and reproductive health (SRH) care. Outpatient psychiatry visits are potential opportunities to connect adolescents to SRH care. This study informs the development of the Link2BC intervention which links adolescents in outpatient psychiatry care to SRH care. METHODS: We conducted group interviews with adolescents (3 groups, 7 total participants) and caregivers (3 groups, 9 total participants) and individual interviews with 8 psychiatry providers who received or provided outpatient psychiatric treatment in clinics in a pediatric hospital in a city in the Midwestern United States. We asked questions about the acceptability of Link2BC, potential implementation needs, and implementation determinants. Using consensus-building techniques, two coders analyzed transcriptions using a codebook informed by the Consolidated Framework for Implementation Research 2.0. RESULTS: Participants agreed on the need for interventions that expand access to SRH care. Adolescents emphasized that services should be confidential and accessible and were open to their psychiatrists introducing SRH topics during appointments. Providers expressed preference for training and clear workflows. Participants agreed that psychiatry providers could serve as liaisons between adolescents and their caregivers to facilitate conversations about contraception. Participants had concerns about time constraints during visits but mentioned few other barriers to the intervention. CONCLUSION: This study demonstrates the acceptability of connecting adolescents in outpatient psychiatry care to contraceptive counseling and informs the refinement and implementation of Link2BC. Integrating contraception counseling in outpatient psychiatry settings is an innovative approach to prevent unintended pregnancy among adolescents by increasing access to SRH care services.

Specifying cross-system collaboration strategies for implementation: a multi-site qualitative study with child welfare and behavioral health organizations.

BACKGROUND: Cross-system interventions that integrate health, behavioral health, and social services can improve client outcomes and expand community impact. Successful implementation of these interventions depends on the extent to which service partners can align frontline services and organizational operations. However, collaboration strategies linking multiple implementation contexts have received limited empirical attention. This study identifies, describes, and specifies multi-level collaboration strategies used during the implementation of Ohio Sobriety Treatment and Reducing Trauma (Ohio START), a cross-system intervention that integrates services across two systems (child welfare and evidence-based behavioral health services) for families that are affected by co-occurring child maltreatment and parental substance use disorders. METHODS: In phase 1, we used a multi-site qualitative design with 17 counties that implemented Ohio START. Qualitative data were gathered from 104 staff from child welfare agencies, behavioral health treatment organizations, and regional behavioral health boards involved in implementation via 48 small group interviews about collaborative approaches to implementation. To examine cross-system collaboration strategies, qualitative data were analyzed using an iterative template approach and content analysis. In phase 2, a 16-member expert panel met to validate and specify the cross-system collaboration strategies identified in the interviews. The panel was comprised of key child welfare and behavioral health partners and scholars. RESULTS: In phase 1, we identified seven cross-system collaboration strategies used for implementation. Three strategies were used to staff the program: (1) contract for expertise, (2) provide joint supervision, and (3) co-locate staff. Two strategies were used to promote service access: (4) referral protocols and (5) expedited access agreements. Two strategies were used to align case plans: (6) shared decision-making meetings, and (7) sharing data. In phase 2, expert panelists specified operational details of the cross-system collaboration strategies, and explained the processes by which strategies were perceived to improve implementation and service system outcomes. CONCLUSIONS: We identified a range of cross-system collaboration strategies that show promise for improving staffing, service access, and case planning. Leaders, supervisors, and frontline staff used these strategies during all phases of implementation. These findings lay the foundation for future experimental and quasi-experimental studies that test the effectiveness of cross-system collaboration strategies.

Administrative Coordination in Non-Profit Human Service Delivery Networks: The Role of Competition and Trust.

Non-profit human service organizations operating within the same regional network are often faced with dual pressure to compete as well as coordinate administrative operations (by sharing funding, staff or space) to enhance efficiency. Emerging evidence has demonstrated that competing organizations coordinate, despite the risks. Trust, or perceived trustworthiness between two organizations may mitigate the negative influence of competition on coordination, however there have been few explicit tests of this hypothesis among non-profit organizations. Drawing on quantitative data collected from a network of 36 non-profit children's behavioral health organizations, this paper empirically tests how competition and perceived trustworthiness interact to influence administrative coordination. Results support the hypothesis that trustworthiness moderates the influence of competition on administrative coordination. Findings suggest that as competing non-profit leaders build trust, the more their agencies coordinate their administrative functions. This study highlights the importance of leaders' perceptions for organizational strategy.

Implementing traumatic brain injury screening in behavioral health treatment settings: results of an explanatory sequential mixed-methods investigation.

BACKGROUND: Traumatic brain injury (TBI) is a complex condition common among individuals treated in behavioral healthcare, but TBI screening has not been adopted in these settings which can affect optimal clinical decision-making. Integrating evidence-based practices that address complex health comorbidities into behavioral healthcare settings remains understudied in implementation science, limited by few studies using theory-driven hypotheses to disentangle relationships between proximal and medial indicators on distal implementation outcomes. Grounded in the Theory of Planned Behavior, we examined providers' attitudes, perceived behavioral control (PBC), subjective norms, and intentions to adopt The Ohio State University TBI Identification Method (OSU TBI-ID) in behavioral healthcare settings. METHODS: We used an explanatory sequential mixed-methods design. In Phase I, 215 providers from 25 organizations in the USA completed training introducing the OSU TBI-ID, followed by a survey assessing attitudes, PBC, norms, and intentions to screen for TBI. After 1 month, providers completed another survey assessing the number of TBI screens conducted. Data were analyzed using structural equation modeling (SEM) with logistic regressions. In Phase II, 20 providers were purposively selected for semi-structured interviews to expand on SEM results. Qualitative data were analyzed using thematic analysis, integrated with quantitative results, and combined into joint displays. RESULTS: Only 25% (55/215) of providers adopted TBI screening, which was driven by motivations to trial the intervention. Providers who reported more favorable attitudes (OR: 0.67, p < .001) and greater subjective norms (OR: 0.12, p < .001) toward TBI screening demonstrated increased odds of intention to screen, which resulted in greater TBI screening adoption (OR: 0.30; p < .01). PBC did not affect intentions or adoption. Providers explained that although TBI screening can improve diagnostic and clinical decision-making, they discussed that additional training, leadership engagement, and state-level mandates are needed to increase the widespread, systematic uptake of TBI screening. CONCLUSIONS: This study advances implementation science by using theory-driven hypothesis testing to disentangle proximal and medial indicators at the provider level on TBI screening adoption. Our mixed-methods approach added in-depth contextualization and illuminated additional multilevel determinants affecting intervention adoption, which guides a more precise selection of implementation strategies.

Developing a typology of network alteration strategies for implementation: a scoping review and iterative synthesis.

BACKGROUND: Social networks transmit knowledge, influence, and resources. These relationships among patients, professionals, and organizations can shape how innovations are disseminated, adopted, implemented, and sustained. Network alteration interventions-interventions that change or rewire social networks-have the potential to be used as implementation strategies. Yet, the types, mechanisms, and effectiveness of these interventions for implementation are unclear. This scoping review and iterative synthesis identified and described network alteration strategies that could be tested for implementation. METHODS: We used forward and backward citation tracking of influential articles on network interventions, bibliometric searches, and hand searches of peer-reviewed social network journals. At least two team members screened article titles/abstracts to identify studies that met inclusion criteria: empirical studies of an intervention, the intervention was designed to alter some element of a social network, and changes in social network metrics were measured at two or more time points. During full-text reviews, information about the network interventions, actors, ties, and main findings was extracted. Reporting was informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). To develop our typology, we synthesized these results using an iterative team-based and consensus-building process. RESULTS: Fifty-three articles met the inclusion criteria. The interventions described were conducted in healthcare systems or behavioral health systems (34%), communities (26.4%), and schools (22.6%). The majority included records describing interventions designed to alter social support, information-sharing, or friendship networks (65%) among individual actors (84.9%), or to increase ties. Eight strategies emerged. Three strategies targeted the general context: (1) change the environment, (2) create groups, and (3) change the composition. Four strategies targeted individual actors: change (4) motivations, (5) skills for networking, (6) knowledge of one's social network, and (7) prominence/roles. One strategy (8) targeted specific ties within the network (targeting a particular pair-wise relationship or changing the nature of an existing tie). CONCLUSION: The network alteration strategies in this typology provide further operational specificity for how implementation strategies target relationships. Advancing these strategies will require greater theoretical specification, the development of strategies that target professionals and organizations, and studies that examine the impact on implementation outcomes.
