Supervisory Alliance as a Moderator of the Effects of Behavioral Rehearsal on TF-CBT Fidelity: Results from a Randomized Trial of Supervision Strategies.

Exposure is an important element of treatment for many evidence-based treatments but can be challenging to implement. Supervision strategies to support exposure delivery may be an important tool to facilitate the use of exposure techniques; however, they must be considered and used in the context of the supervisory alliance. The present study examined relations between supervisory alliance and fidelity to the trauma narrative (TN; i.e., imaginal exposure) component of Trauma-Focused Cognitive Behavioral Therapy. We also examined how supervisory alliance moderated the effect of behavioral rehearsal use in supervision on TN fidelity. We analyzed data from a randomized controlled trial, in which forty-two supervisors and their clinicians (N = 124) from 28 Washington State community-based mental health offices participated. Clinicians were randomized to receive one of two supervision conditions-symptom and fidelity monitoring (SFM) or SFM with behavioral rehearsal (SFM + BR). Supervisory alliance alone did not predict delivery (i.e., occurrence) or extensiveness of delivery of the trauma narrative. Client-focused supervisory alliance moderated the effectiveness of behavioral rehearsal-as client-focused alliance increased, the odds of delivering the TN also increased significantly. Future research should further investigate how to appropriately match supervision techniques with supervisory dyads and explore the interplay of alliance with supervision techniques a supervisor might employ.

Effectiveness of a Brief Engagement, Problem-Solving, and Triage Strategy for High School Students: Results of a Randomized Study.

Schools offer an advantageous setting for the prevention, early identification, and treatment of mental health problems for youth. However, school mental health (SMH) services are typically not based on evidence for effectiveness, nor are they efficiently delivered, with SMH practitioners (SMHPs) able to only treat a small number of students in need. The current study evaluated the feasibility, acceptability, efficiency, and outcomes of a four-session assessment, engagement, problem-solving, and triage strategy for SMHPs that aimed to improve efficiency while being based on elements of evidence-based care. The study, conducted in 15 US school districts in three states, used stratified random assignment to assign 49 high schools and their participating SMHP(s) to either the Brief Intervention for School Clinicians (BRISC; N = 259 students) or services as usual (SAU; N = 198 students). SMHPs implemented BRISC elements with adequate to excellent fidelity and reported the strategy was feasible and well-aligned with presenting problems. Students assigned to BRISC reported significantly greater engagement in SMH at 2 months and completion of SMH treatment by 6 months. BRISC-assigned SMHPs reported significantly greater treatment completion after four sessions (53.4%) compared to SAU (15.4%). Students in the BRISC condition also reported significantly greater reduction in problem severity as evaluated by the Youth Top Problems Assessment. No differences were found for anxiety or depression symptoms or overall functioning. Results indicate that BRISC is a feasible early intervention and triage strategy that may aid in more efficient provision of SMH services with no compromise to SMH effectiveness.

Usability Issues in Evidence-Based Psychosocial Interventions and Implementation Strategies: Cross-project Analysis.

BACKGROUND: People often prefer evidence-based psychosocial interventions (EBPIs) for mental health care; however, these interventions frequently remain unavailable to people in nonspecialty or integrated settings, such as primary care and schools. Previous research has suggested that usability, a concept from human-centered design, could support an understanding of the barriers to and facilitators of the successful adoption of EBPIs and support the redesign of EBPIs and implementation strategies. OBJECTIVE: This study aimed to identify and categorize usability issues in EBPIs and their implementation strategies. METHODS: We adapted a usability issue analysis and reporting format from a human-centered design. A total of 13 projects supported by the National Institute of Mental Health-funded Accelerating the Reach and Impact of Treatments for Youth and Adults with Mental Illness Center at the University of Washington used this format to describe usability issues for EBPIs and implementation strategies with which they were working. Center researchers used iterative affinity diagramming and coding processes to identify usability issue categories. On the basis of these categories and the underlying issues, we propose heuristics for the design or redesign of EBPIs and implementation strategies. RESULTS: The 13 projects reported a total of 90 usability issues, which we categorized into 12 categories, including complex and/or cognitively overwhelming, required time exceeding available time, incompatibility with interventionist preference or practice, incompatibility with existing workflow, insufficient customization to clients/recipients, intervention buy-in (value), interventionist buy-in (trust), overreliance on technology, requires unavailable infrastructure, inadequate scaffolding for client/recipient, inadequate training and scaffolding for interventionists, and lack of support for necessary communication. These issues range from minor inconveniences that affect a few interventionists or recipients to severe issues that prevent all interventionists or recipients in a setting from completing part or all of the intervention. We propose 12 corresponding heuristics to guide EBPIs and implementation strategy designers in preventing and addressing these usability issues. CONCLUSIONS: Usability issues were prevalent in the studied EBPIs and implementation strategies. We recommend using the lens of usability evaluation to understand and address barriers to the effective use and reach of EBPIs and implementation strategies.

Understanding Psychological Distress and Protective Factors Amongst Older Adults During the COVID-19 Pandemic.

OBJECTIVES: This study examined the emotional distress and loneliness during COVID-19 and the roles of resiliency and activities. DESIGN: A cross-sectional national survey. SETTING: Amazon Mechanical Turk (mTurk) and Prolific Research Platforms. PARTICIPANTS: Five hundred and one U.S. dwelling English-speaking adults 60 years old and older. MEASUREMENTS: Participants completed an online survey with the PHQ-9; GAD-7; Short Health Anxiety Inventory; 3-item UCLA Loneliness scale; PROMIS measures of global health, instrumental, and emotional support; 10-item Connor-Davidson Resilience Scale; and COVID-19 needs assessment. RESULTS: Across the sample 13% reported moderate depressive symptoms, 9% reported moderate anxiety symptoms, and 26% endorsed being "lonely." The emotionally distressed group endorsed more loneliness, lower resiliency, less physical exercise, and worse physical health. The low Socio-Economic Status group endorsed less loneliness, less likely to engage in physical exercise and worse physical health.The lonely group endorsed less resilience, less physical exercise, and worse physical health. A multiple logistic regression found that resilience, socioeconomic status, and physical health were significant predictors of loneliness, whereas global health was the best predictor of emotional distress. CONCLUSIONS: Even after prolonged social distancing, older adults in this study did not report greater psychological distress compared to earlier studies of older adults during COVID-19. Older adults with lower SES, worse physical health, and less resiliency, were more likely to report more loneliness. It is this group that should be the focus of intervention.

Behavioral Activation and Depression Symptomatology: Longitudinal Assessment of Linguistic Indicators in Text-Based Therapy Sessions.

BACKGROUND: Behavioral activation (BA) is rooted in the behavioral theory of depression, which states that increased exposure to meaningful, rewarding activities is a critical factor in the treatment of depression. Assessing constructs relevant to BA currently requires the administration of standardized instruments, such as the Behavioral Activation for Depression Scale (BADS), which places a burden on patients and providers, among other potential limitations. Previous work has shown that depressed and nondepressed individuals may use language differently and that automated tools can detect these differences. The increasing use of online, chat-based mental health counseling presents an unparalleled resource for automated longitudinal linguistic analysis of patients with depression, with the potential to illuminate the role of reward exposure in recovery. OBJECTIVE: This work investigated how linguistic indicators of planning and participation in enjoyable activities identified in online, text-based counseling sessions relate to depression symptomatology over time. METHODS: Using distributional semantics methods applied to a large corpus of text-based online therapy sessions, we devised a set of novel BA-related categories for the Linguistic Inquiry and Word Count (LIWC) software package. We then analyzed the language used by 10,000 patients in online therapy chat logs for indicators of activation and other depression-related markers using LIWC. RESULTS: Despite their conceptual and operational differences, both previously established LIWC markers of depression and our novel linguistic indicators of activation were strongly associated with depression scores (Patient Health Questionnaire [PHQ]-9) and longitudinal patient trajectories. Emotional tone; pronoun rates; words related to sadness, health, and biology; and BA-related LIWC categories appear to be complementary, explaining more of the variance in the PHQ score together than they do independently. CONCLUSIONS: This study enables further work in automated diagnosis and assessment of depression, the refinement of BA psychotherapeutic strategies, and the development of predictive models for decision support.

Examining the Effects of a Brief, Group-Based Motivational Implementation Strategy on Mechanisms of Teacher Behavior Change.

Training and consultation are core implementation strategies used to support the adoption and delivery of evidence-based prevention programs (EBPPs), but are often insufficient alone to effect teacher behavior change. Motivational interviewing (MI) and related behavior change techniques (e.g., strategic education, social influence, implementation planning) delivered in a group format offer promising supplements to training and consultation to improve EBPP implementation. Beliefs and Attitudes for Successful Implementation in Schools for Teachers (BASIS-T) is a theoretically informed, motivational implementation strategy delivered in a group format prior to and immediately after EBPP training. The purpose of this study was to examine the proximal effects of BASIS-T on hypothesized mechanisms of behavior change (e.g., attitudes, subjective norms, intentions to implement) in the context of teachers receiving training and consultation to implement the Good Behavior Game. As part of a pilot trial, 83 elementary school teachers from 9 public elementary schools were randomly assigned (at the school-level to reduce contamination across participants) to a BASIS-T (n = 44) or active comparison control (n = 39) condition, with both conditions receiving Good Behavior Game (GBG) training and consultation. A series of mixed effects models revealed meaningful effects favoring BASIS-T on a number of hypothesized mechanisms of behavior change leading to increased motivation to implement GBG. The implications, limitations, and directions for future research on the use of MI with groups of individuals and other behavior change techniques to increase the yield of training and consultation are discussed.

A Digital Feedback System to Support Implementation of Measurement-Based Care by School-Based Mental Health Clinicians.

Evidence supports the utility of measurement-based care (MBC) to improve youth mental health outcomes, but clinicians rarely engage in MBC practices. Digital measurement feedback systems (MFS) may reflect a feasible strategy to support MBC adoption and sustainment. This pilot study was initiated to evaluate the impact of a MFS and brief consultation supports to facilitate MBC uptake and sustainment among mental health clinicians in the education sector, the most common mental health service delivery setting for youth. Following an initial training in MBC, 14 clinicians were randomized to either a digital MFS and brief consultation supports or control. Baseline ratings of MBC attitudes, skill, and use were collected. In addition, daily assessment ratings tracked 2 core MBC practices (i.e., assessment tool administration, provision of feedback) over a 6-month follow-up period. Clinicians in the MFS condition demonstrated rapid increases in both MBC practices, whereas the control group did not significantly change. For clinicians in the MFS group, consultation effects were significant for feedback and approached significance for administration. Over the follow-up period, average decreases in the current study were moderate with only 1 of the 2 outcome variables (administration) decreasing significantly. Inspection of individual clinician trajectories revealed substantial within-group trend variation. MFS may represent an effective MBC implementation strategy beyond initial training, although individual clinician response is variable. Identifying feasible and impactful implementation strategies is critical given the ability of MBC to support precision health care.

Measurement Based Care in Child Welfare-Involved Children and Youth: Reliability and Validity of the PSC-17.

This study evaluates whether the psychometric properties of the Pediatric Symptoms Checklist-17 (PSC-17), a common behavioral health measure typically used as a dichotomous screening tool for mental health needs, support its use as a continuous measure for tracking behavioral health over time. A total of 6492 foster parents of children and youth aged 5.5-17 completed the PSC-17. Convergent and discriminant validity was assessed by comparing raw PSC-17 subscale scores with associated outcomes (e.g. psychiatric diagnoses). Long-term test-retest reliability was assessed over 6 months. Scores on the PSC-17 demonstrated good convergent and divergent validity. PSC-17 subscale scores were most strongly associated with analogous diagnoses. Test-retest reliability was moderate, as expected for a time window of this length. This study provides moderate support for the psychometric qualities of the PSC-17 when used with children and youth in the child welfare system as a continuous measure of psychosocial functioning over time.

Identifying Psychosocial Problems Among Children and Youth in the Child Welfare System Using the PSC-17: Exploring Convergent and Discriminant Validity with Multiple Informants.

Youth who enter foster care are at risk of mental health need, but questions arise as to the validity of their self-reported symptomatology. This study examines the screening validity of the youth-report version of the Pediatric Symptom Checklist-17 (PSC-17) in a child welfare population. Data come from 2389 youth who completed a version of the PSC-17 adapted for youth report, and their biological and foster parents who completed the parent-report version. Youth also completed a shortened version of the Screen for Child Anxiety Related Disorders (SCARED). Convergent and discriminant validity of the PSC-17 was assessed using multi-trait multi-method matrices. The PSC-17's internalizing subscale was strongly correlated, attention subscale was moderately correlated, and externalizing subscale was weakly correlated with the SCARED's anxiety and PTSD subscales. Comparing youth and foster parent scores, the PSC-17 had moderate convergent validity and weak/fair discriminant validity. Comparing youth, foster parent, and biological parent scores, the PSC-17 had moderate convergent validity and weak/fair discriminant validity. The current study provides some support for the validity of the PSC-17 for the population of youth in foster care.

Agreement and Discrepancy Between Supervisor and Clinician Alliance: Associations with Clinicians' Perceptions of Psychological Climate and Emotional Exhaustion.

Despite increasing interest in supervision as a leverage point for bolstering public mental health services, the potential influence of supervisory alliance on organizations and direct service providers remains understudied, particularly in the context of supporting evidence-based treatment (EBT) use. This study examined agreement and discrepancy between supervisor and clinician ratings of alliance associated with clinicians' perceptions of psychological climate and emotional exhaustion. Results indicated that discrepancies in alliance ratings were common and associated with clinicians' perceptions of psychological climate. These findings have important implications for collaboration among supervisors and clinicians within a community mental health organizational context and the provision of EBTs.

Community Engagement Strategies for Implementation of a Policy Supporting Evidence-Based Practices: A Case Study of Washington State.

After nearly two decades of cultivating an evidence based practice milieu in Washington State, the 2012 legislature passed House Bill 2536 (HB 2536) to promote the increased uptake and use of evidence based practices in the child welfare, juvenile justice and child behavioral health systems. The current paper examines stakeholder participation and engagement in HB 2536 during the first year of its implementation. The current paper describes the community response, influence, and engagement during the drafting of the bill language. It then describes initial policy implementation and community engagement efforts within a framework of implementation strategies (Powell et al. in Medical Care Research and Review 69:123-57, 2012). Analysis includes common concerns, statements of support, and suggestions from diverse stakeholder groups. Discussion reviews the lessons learned and future directions, including opportunities for additional collaborations with community stakeholders in the subsequent years of HB 2536 implementation.

Behavioral Rehearsal for Analogue Fidelity: Feasibility in a State-Funded Children's Mental Health Initiative.

A substantial number of evidence-based treatments (EBTs) are available, but are delivered infrequently in public mental health. To improve the quality of care, some states and systems have focused on EBT training; however, these efforts have rarely included objective measurement of clinician fidelity because of feasibility issues. The primary goal of the current study was evaluating the feasibility of the behavioral rehearsal (BR) method to assess "analogue fidelity" in a children's mental health quality improvement initiative. Results indicated low-but representative-clinician participation. Participants demonstrated greatest improvement at post-training with maintenance or decreases at 6-months (post-consultation). Implications for future use of BR are discussed.

Community-Sourced Intervention Programs: Review of Submissions in Response to a Statewide Call for "Promising Practices".

This study was initiated to add to the nascent literature on locally-grown intervention programs in the youth mental health, child welfare, and juvenile justice service sectors, many of which demonstrate practice-based or community-defined evidence, but may not have been subjected to empirical evaluation. Characteristics of applications submitted in response to three public calls for additions to an inventory of research-supported intervention programs were reviewed on evidence for effectiveness, the use of key quality assurance (QA) elements (e.g., clearly specified training or integrity monitoring procedures), and cultural specificity. Findings indicate that four QA processes were identified in approximately half of all submissions: a specific initial training process, the existence of intervention integrity measures, routine outcome monitoring, and ongoing support post-training. An initial training process and integrity measurement were more commonly described among programs determined to have greater research evidence for their effectiveness. Overall, cultural elements were described relatively infrequently and most often reflected surface-level program delivery characteristics (e.g., offering services in languages other than English). Discussion is focused on the alignment of submitted programs with the larger literatures focused on implementation science and cultural competence.

The Juggling Act of Supervision in Community Mental Health: Implications for Supporting Evidence-Based Treatment.

Supervisors are an underutilized resource for supporting evidence-based treatments (EBTs) in community mental health. Little is known about how EBT-trained supervisors use supervision time. Primary aims were to describe supervision (e.g., modality, frequency), examine functions of individual supervision, and examine factors associated with time allocation to supervision functions. Results from 56 supervisors and 207 clinicians from 25 organizations indicate high prevalence of individual supervision, often alongside group and informal supervision. Individual supervision serves a wide range of functions, with substantial variation at the supervisor-level. Implementation climate was the strongest predictor of time allocation to clinical and EBT-relevant functions.

A Research Framework for Understanding the Practical Impact of Family Involvement in the Juvenile Justice System: The Juvenile Justice Family Involvement Model.

Family involvement is recognized as a critical element of service planning for children's mental health, welfare and education. For the juvenile justice system, however, parents' roles in this system are complex due to youths' legal rights, public safety, a process which can legally position parents as plaintiffs, and a historical legacy of blaming parents for youth indiscretions. Three recent national surveys of juvenile justice-involved parents reveal that the current paradigm elicits feelings of stress, shame and distrust among parents and is likely leading to worse outcomes for youth, families and communities. While research on the impact of family involvement in the justice system is starting to emerge, the field currently has no organizing framework to guide a research agenda, interpret outcomes or translate findings for practitioners. We propose a research framework for family involvement that is informed by a comprehensive review and content analysis of current, published arguments for family involvement in juvenile justice along with a synthesis of family involvement efforts in other child-serving systems. In this model, family involvement is presented as an ascending, ordinal concept beginning with (1) exclusion, and moving toward climates characterized by (2) information-giving, (3) information-eliciting and (4) full, decision-making partnerships. Specific examples of how courts and facilities might align with these levels are described. Further, the model makes predictions for how involvement will impact outcomes at multiple levels with applications for other child-serving systems.

Effectiveness of wraparound versus case management for children and adolescents: results of a randomized study.

In this study, we compared service experiences and outcomes for youths with serious emotional disorder (SED) randomly assigned to care coordination via a defined wraparound process (n = 47) versus more traditional intensive case management (ICM; n = 46) The wraparound group received more mean hours of care management and services; however, there ultimately were no group differences in restrictiveness of residential placement, emotional and behavioral symptoms, or functioning. Wraparound implementation fidelity was found to be poor. Organizational culture and climate, and worker morale, were poorer for the wraparound providers than the ICM group. Results suggest that, for less-impaired youths with SED, less intensive options such as ICM may be equally effective to poor-quality wraparound delivered in the absence of wraparound implementation supports and favorable system conditions.

Family voice with informed choice: coordinating wraparound with research-based treatment for children and adolescents.

The wraparound process is a type of individualized, team-based care coordination that has become central to many state and system efforts to reform children's mental health service delivery for youths with the most complex needs and their families. Although the emerging wraparound research base is generally positive regarding placements and costs, effect sizes are smaller for clinical and functional outcomes. This article presents a review of literature on care coordination and wraparound models, with a focus on theory and research that indicates the need to better connect wraparound-enrolled children and adolescents to evidence-based treatment (EBT). The article goes on to describe how recently developed applications of EBT that are based on quality improvement and flexible application of "common elements" of research-based care may provide a more individualized approach that better aligns with the philosophy and procedures of the wraparound process. Finally, this article presents preliminary studies that show the feasibility and potential effectiveness of coordinating wraparound with the Managing and Adapting Practice system, and discusses intervention development and research options that are currently under way.

Getting cozy with causality: Advances to the causal pathway diagramming method to enhance implementation precision.

Background: Implementation strategies are theorized to work well when carefully matched to implementation determinants and when factors-preconditions, moderators, etc.-that influence strategy effectiveness are prospectively identified and addressed. Existing methods for strategy selection are either imprecise or require significant technical expertise and resources, undermining their utility. This article outlines refinements to causal pathway diagrams (CPDs), a method for articulating the causal process through which implementation strategies work and offers illustrations of their use. Method: CPDs are a visualization tool to represent an implementation strategy, its mechanism(s) (i.e., the processes through which a strategy is thought to operate), determinants it is intended to address, factors that may impede or facilitate its effectiveness, and the series of outcomes that should be expected if the strategy is operating as intended. We offer principles for constructing CPDs and describe their key functions. Results: Applications of the CPD method by study teams from two National Institute of Health-funded Implementation Science Centers and a research grant are presented. These include the use of CPDs to (a) match implementation strategies to determinants, (b) understand the conditions under which an implementation strategy works, and (c) develop causal theories of implementation strategies. Conclusions: CPDs offer a novel method for implementers to select, understand, and improve the effectiveness of implementation strategies. They make explicit theoretical assumptions about strategy operation while supporting practical planning. Early applications have led to method refinements and guidance for the field.

Advances to the Causal Pathway Diagramming Method to Enhance Implementation Precision Plain Language Summary Implementation strategies often fail to produce meaningful improvements in the outcomes we hope to impact. Better tools for choosing, designing, and evaluating implementation strategies may improve their performance. We developed a tool, causal pathway diagrams (CPD), to visualize and describe how implementation strategies are expected to work. In this article, we describe refinements to the CPD tool and accompanying approach. We use real illustrations to show how CPDs can be used to improve how to match strategies to barriers, understand the conditions in which those strategies work best, and develop generalizable theories describing how implementation strategies work. CPDs can serve as both a practical and scientific tool to improve the planning, deployment, and evaluation of implementation strategies. We demonstrate the range of ways that CPDs are being used, from a highly practical tool to improve implementation practice to a scientific approach to advance testing and theorizing about implementation strategies.

Development of a method for Making Optimal Decisions for Intervention Flexibility during Implementation (MODIFI): a modified Delphi study.

BACKGROUND: Intervention adaptation is often necessary to improve the fit between evidence-based practices/programs and implementation contexts. Existing frameworks describe intervention adaptation processes but do not provide detailed steps for prospectively designing adaptations, are designed for researchers, and require substantial time and resources to complete. A pragmatic approach to guide implementers through developing and assessing adaptations in local contexts is needed. The goal of this project was to develop Making Optimal Decisions for Intervention Flexibility during Implementation (MODIFI), a method for intervention adaptation that leverages human centered design methods and is tailored to the needs of intervention implementers working in applied settings with limited time and resources. METHOD: MODIFI was iteratively developed via a mixed-methods modified Delphi process. Feedback was collected from 43 implementation research and practice experts. Two rounds of data collection gathered quantitative ratings of acceptability and inclusion (Round 1) and feasibility (Round 2), as well as qualitative feedback regarding MODIFI revisions analyzed using conventional content analysis. RESULTS: In Round 1, most participants rated all proposed components as essential but identified important avenues for revision which were incorporated into MODIFI prior to Round 2. Round 2 emphasized feasibility, where ratings were generally high and fewer substantive revisions were recommended. Round 2 changes largely surrounded operationalization of terms/processes and sequencing of content. Results include a detailed presentation of the final version of the three-step MODIFI method (Step 1: Learn about the users, local context, and intervention; Step 2: Adapt the intervention; Step 3: Evaluate the adaptation) along with a case example of its application. DISCUSSION: MODIFI is a pragmatic method that was developed to extend the contributions of other research-based adaptation theories, models, and frameworks while integrating methods that are tailored to the needs of intervention implementers. Guiding teams to tailor evidence-based interventions to their local context may extend for whom, where, and under what conditions an intervention can be effective.

Protocol for a hybrid type 3 effectiveness-implementation trial of a pragmatic individual-level implementation strategy for supporting school-based prevention programming.

BACKGROUND: For approximately one in five children who have social, emotional, and behavioral (SEB) challenges, accessible evidence-based prevention practices (EBPPs) are critical. In the USA, schools are the primary setting for children's SEB service delivery. Still, EBPPs are rarely adopted and implemented by front-line educators (e.g., teachers) with sufficient fidelity to see effects. Given that individual behavior change is ultimately required for successful implementation, focusing on individual-level processes holds promise as a parsimonious approach to enhance impact. Beliefs and Attitudes for Successful Implementation in Schools for Teachers (BASIS-T) is a pragmatic, multifaceted pre-implementation strategy targeting volitional and motivational mechanisms of educators' behavior change to enhance implementation and student SEB outcomes. This study protocol describes a hybrid type 3 effectiveness-implementation trial designed to evaluate the main effects, mediators, and moderators of the BASIS-T implementation strategy as applied to Positive Greetings at the Door, a universal school-based EBPP previously demonstrated to reduce student disruptive behavior and increase academic engagement. METHODS: This project uses a blocked randomized cohort design with an active comparison control (ACC) condition. We will recruit and include approximately 276 teachers from 46 schools randomly assigned to BASIS-T or ACC conditions. Aim 1 will evaluate the main effects of BASIS-T on proximal implementation mechanisms (attitudes, subjective norms, self-efficacy, intentions to implement, and maintenance self-efficacy), implementation outcomes (adoption, reach, fidelity, and sustainment), and child outcomes (SEB, attendance, discipline, achievement). Aim 2 will examine how, for whom, under what conditions, and how efficiently BASIS-T works, specifically by testing whether the effects of BASIS-T on child outcomes are (a) mediated via its putative mechanisms of behavior change, (b) moderated by teacher factors or school contextual factors, and (c) cost-effective. DISCUSSION: This study will provide a rigorous test of BASIS-T-a pragmatic, theory-driven, and generalizable implementation strategy designed to target theoretically-derived motivational mechanisms-to increase the yield of standard EBPP training and support strategies.
