Helping Practitioners Stop, Drop, and Roll: Suggestions to Help Improve Responses to Intense Clinical Events.

Community practitioners inconsistently implement evidence-based interventions. Implementation science emphasizes the importance of some practitioner characteristics, such as motivation, but factors such as practitioners' emotion regulation and cognitive processing receive less attention. Practitioners often operate in stressful environments that differ from those in which they received training. They may underestimate the impact of their emotional state on their ability to deliver evidence-based interventions. This "hot-cold state empathy gap" is not well studied in mental health care. In this Open Forum, the authors describe scenarios where this gap is affecting practitioners' ability to implement evidence-based practices. The authors provide suggestions to help practitioners plan for stressful situations.

Mobile Crisis Services: A Clinician Survey of Current Suicide Prevention Practices and Barriers to Care Delivery.

Mobile crisis teams (MCTs) deploy clinicians to assist individuals in acute crisis in the community. Little is known about the extent to which these teams provide evidence-based practices (EBPs) for suicide prevention nor the barriers they face. We surveyed 120 MCT clinicians across the United States about their: (1) use of suicide risk screening and assessment tools; (2) strategies used to address suicide risk (both EBPs and non-EBPs); and (3) perceived barriers to high-quality MCT services. Nearly all clinicians reported use of validated suicide screening tools and generic "safety planning." However, a sizeable minority also reported use of non-EBPs. Open-ended responses suggested many client/family-, clinician-, and systems-level barriers to MCT use of EBPs for suicide prevention. We identified several targets for future implementation efforts, including the need for de-implementation strategies to reduce use of ineffective and potentially harmful practices, and unique aspects of MCTs that require tailored implementation supports.

Implementation of an Adapted Fidelity Scale for Pennsylvania Coordinated Specialty Care Programs for First Episode Psychosis.

Coordinated Specialty Care (CSC) is an evidence-based model for early intervention of first episode psychosis (FEP). Monitoring fidelity to CSC models is essential for proper evaluation of program outcomes and quality improvement. To address variability across CSC programs and fidelity assessment-associated burden, an adapted fidelity scale was developed and implemented statewide in Pennsylvania. This report describes the design and preliminary performance of the adapted scale. The Pennsylvania FEP Fidelity Scale (PA-FEP-FS) assesses adherence to the CSC model by focusing on essential model components of other established fidelity scales, in tandem with program evaluation data. Initial data from fourteen PA-FEP sites from 2018 to 2021 were examined as preliminary validation. Assessment-associated burdens and costs were also estimated. PA-FEP-FS captured essential components of CSC models and proved feasible for implementation across varying program structures, while minimizing burden and cost. Programs utilized annual feedback as CSC benchmarks, evidenced by increased scores over time. PA-FEP-FS provides a model for adapting CSC fidelity scales to meet state- or local-level requirements while reducing assessment burdens and costs that may be associated with existing scales.

An exposure-based implementation strategy to decrease clinician anxiety about implementing suicide prevention evidence-based practices: protocol for development and pilot testing (Project CALMER).

BACKGROUND: Clinicians often report that their own anxiety and low self-efficacy inhibit their use of evidence-based suicide prevention practices, including gold-standard screening and brief interventions. Exposure therapy to reduce clinician maladaptive anxiety and bolster self-efficacy use is a compelling but untested approach to improving the implementation of suicide prevention evidence-based practices (EBPs). This project brings together an interdisciplinary team to leverage decades of research on behavior change from exposure theory to design and pilot test an exposure-based implementation strategy (EBIS) to target clinician anxiety to improve suicide prevention EBP implementation. METHODS: We will develop, iteratively refine, and pilot test an EBIS paired with implementation as usual (IAU; didactic training and consultation) in preparation for a larger study of the effect of this strategy on reducing clinician anxiety, improving self-efficacy, and increasing use of the Columbia Suicide Severity Rating Scale and the Safety Planning Intervention in outpatient mental health settings. Aim 1 of this study is to use participatory design methods to develop and refine the EBIS in collaboration with a stakeholder advisory board. Aim 2 is to iteratively refine the EBIS with up to 15 clinicians in a pilot field test using rapid cycle prototyping. Aim 3 is to test the refined EBIS in a pilot implementation trial. Forty community mental health clinicians will be randomized 1:1 to receive either IAU or IAU + EBIS for 12 weeks. Our primary outcomes are EBIS acceptability and feasibility, measured through questionnaires, interviews, and recruitment and retention statistics. Secondary outcomes are the engagement of target implementation mechanisms (clinician anxiety and self-efficacy related to implementation) and preliminary effectiveness of EBIS on implementation outcomes (adoption and fidelity) assessed via mixed methods (questionnaires, chart-stimulated recall, observer-coded role plays, and interviews). DISCUSSION: Outcomes from this study will yield insight into the feasibility and utility of directly targeting clinician anxiety and self-efficacy as mechanistic processes informing the implementation of suicide prevention EBPs. Results will inform a fully powered hybrid effectiveness-implementation trial to test EBIS' effect on implementation and patient outcomes.

COVID-19 Impacts on Pennsylvania Coordinated Specialty Care for Early Psychosis Participants.

OBJECTIVES: The coronavirus disease (COVID-19) pandemic produced swift, extensive changes in daily life, including for first-episode psychosis (FEP) clients. This study examined pandemic-related psychosocial impacts to clients while engaged in Coordinated Specialty Care (CSC). We also examined FEP client vaccination rates, as vaccinations can reduce hospitalizations/deaths, and related worries. METHODS: Thirty-one clients (45% female; ages 13-39; 26% black, 61% white) from Pennsylvania (PA) CSC outpatient programs completed an online survey evaluating exposure to COVID-19, associated worries, coping, and safety strategies. Descriptive statistics characterized responses and demographic group differences. Additional program evaluation data informed vaccination rates for PA FEP clients. RESULTS: Participants reported substantial pandemic-related impacts to daily life. Many clients reported improved safety measures to protect themselves/others from COVID-19. Clients largely denied substantial worries about infection for themselves, reporting greater concern for loved ones. Multiple coping strategies were endorsed, which, with few exceptions, did not differ among demographic groups. FEP clients had a low reported rate of vaccination (28.6%) as of September 2021. CONCLUSIONS: Observed prolonged pandemic effects may alter FEP client progress in CSC. Stakeholders should be prepared to adjust FEP treatment accordingly in the event of a similar disaster. Concentrated vaccination efforts may be necessary for this population.

Implementing a resilience coach program to support first year housestaff during the COVID-19 pandemic: early pilot results and comparison with non-housestaff sessions.

BACKGROUND: In response to the COVID-19 pandemic, we launched the Penn Medicine Coping First Aid program to provide psychosocial supports to our health system community. Our approach leveraged lay health worker volunteers trained in principles of Psychological First Aid to deliver coaching services through a centralized virtual platform. METHODS: We emailed all (n = 408) first year housestaff (i.e., residents and fellows) with an invitation to schedule a session with a resilience coach. We compared the mental health concerns, symptoms, and Psychological First Aid techniques recorded in (n = 67) first year housestaff sessions with (n = 91) sessions of other employees in the health system. RESULTS: Between June and November 2020, forty-six first year housestaff attended at least one resilience coaching session. First year housestaff most commonly presented with feelings of anxiety and sadness and shared concerns related to the availability of social support. Resilience coaches most frequently provided practical assistance and ensured safety and comfort to first year housestaff. First year housestaff reported fewer physical or mental health symptoms and held shorter sessions with resilience coaches than non-housestaff. CONCLUSIONS: This work offers insights on how to address psychosocial functioning through low-intensity interventions delivered by lay personnel. More research is needed to understand the efficacy of this program and how best to engage housestaff in wellness and resilience programs throughout training, both during and beyond COVID-19.

To Proceed Via Telehealth or Not? Considerations for Pediatric Anxiety and Related Disorders Beyond COVID-19.

The COVID-19 pandemic accelerated a widespread shift to telehealth among mental health professionals to prioritize both providers' and clients' safety. Telehealth is likely here to stay; however, there is limited practical guidance for clinicians about how to make decisions regarding who should proceed with care via telehealth versus in-person. There also is virtually no data on the effectiveness of hybrid approaches to care; yet this can be an attractive option with potential clinical benefit. This paper provides practice-informed guidance to support shared clinical decision-making between clinicians and families to decide whether to engage in therapy services in-person or via telehealth. We specifically focus on decision-making guidance relevant for youth with anxiety or related disorders, given the unique implications of telehealth for these youth. Guided by the three-legged stool of evidence-based practice, we discuss how clinicians can use principles of shared decision-making to inform clinical recommendations about treatment modality.

An Assessment of Faculty Perceptions of Wellness Needs and Strategies to Optimize Engagement With Wellness Resources in Academic Medicine.

OBJECTIVE: Faculty at academic medical institutions are at increased risk for burnout. This study aimed to assess faculty perceptions of wellness needs and identify strategies to optimize engagement with individualized wellness resources. METHODS: Semistructured interviews were conducted with 37 faculty members in one US academic medical center. RESULTS: Participants identified significant barriers to achieving emotional health and wellness goals. Areas where participants identified needing the most support included interpersonal relationships, accountability for wellness goals, career support, financial resources, and mentorship. Most participants were unaware of all wellness resources available at their institution. Participants recommended regular marketing and emphasizing confidentiality of employer-sponsored programs. They also provided feedback on specific dissemination and marketing methods. CONCLUSIONS: This research underscores the need for wellness resources for faculty and the importance of intentional dissemination of these resources to optimize uptake.

Therapist perceptions of experiential training for exposure therapy.

BACKGROUND: Despite evidence for its efficacy, exposure therapy for anxiety is rarely used in routine care settings. Efforts to address one major barrier to its use - therapists' negative beliefs about exposure - have included therapist-level implementation strategies, such as training and consultation. Experiential training, in which therapists themselves undergo exposures, has recently demonstrated feasibility, acceptability and preliminary effectiveness for increasing exposure use. AIMS: This study aimed to assess: (1) therapists' perceptions of experiential training and (2) barriers and facilitators to implementing exposure following training. METHOD: Therapists who underwent experiential training (n=12) completed qualitative interviews and quantitative questionnaires. Interviews were coded using an integrated approach, combining both inductive and deductive approaches. Mixed methods analyses examined how themes varied by practice setting (community mental health versus private practice) and exposure use. RESULTS: Results highlight how therapist-level factors, such as clinician self-efficacy, interact with inner- and outer-setting factors. Participants reported positive perceptions of exposure after training; they noted that directly addressing myths about exposure and experiencing exposures themselves improved their attitudes toward exposure. Consistent with prior literature, issues such as insufficient supervisory support, organizational constraints, and client characteristics made it challenging to implement exposures. DISCUSSION: Results highlight the benefits of experiential training, while also highlighting the need to consider contextual determinants. Differences in responses across practice settings highlight areas for intervention and the importance of tailoring implementation strategies. Barriers that were specific to therapists who did not use exposure (e.g. hesitancy about its appropriateness for most clients) point to directions for future implementation efforts.

Tele-mental Health Transitions for Pennsylvania Coordinated Specialty Care Programs for Early Psychosis During the COVID-19 Pandemic.

This study examined provider and client perspectives of tele-mental health (TMH) in early psychosis care during the COVID-19 pandemic. To achieve this goal, thirty-three mental health providers and 31 clients from Pennsylvania Coordinated Specialty Care (CSC) programs completed web-based surveys assessing TMH usage, experiences, and perceptions between May and September 2020. Three additional TMH-related questions were asked two years later of PA CSC Program Directors between Feb and March 2022. Descriptive statistics characterized responses. Open-ended items were coded and grouped into themes for qualitative synthesis. As early as mid-2020, participants reported extensive use of TMH technologies, including telephone and video visits. Although most providers and clients preferred in-person care to TMH, most clients still found TMH to be comparable to or better than in-person care; 94% of clients indicated interest in future TMH services. Providers also noted more successes than challenges with TMH. Nine themes emerged regarding provider-perceived client characteristics that could benefit from TMH and were grouped into two categories: client-level (access to technology, comfort with technology, transportation, young age, symptom severity, functioning level, motivation for treatment adherence) and interpersonal-level (external support systems and engagement with program prior to the pandemic) characteristics. Two years later, program directors reported continued perceived advantages of TMH in CSCs, although some barriers persisted. Despite the unexpected shift to TMH in early psychosis programs during the COVID-19 pandemic, findings indicated a relatively positive transition to TMH and perceived promise of TMH as a sustained part of routine care.

Preliminary Implementation Outcomes of a Free Online Toolkit to Support Exposure Therapy Implementation for Youth.

Background: Exposure therapy ("exposure") for youth anxiety is highly underutilized in clinical practice. Asynchronous, online implementation strategies such as online toolkits hold promise as pragmatic approaches for extending the sustainability of evidence-based interventions, but their long-term usage, perceived utility, and impact are rarely studied. Objective: This study presents three-year preliminary implementation outcomes for a free, online toolkit to support exposure therapy use with youth: the Resource for Exposure for Anxiety Disordered Youth (READY; www.bravepracticeforkids.com). Implementation outcomes of interest included READY usage statistics, adoption, perceived utility, and clinician exposure use. Methods: Web analytics characterized usage patterns. A survey of READY users (N = 49; M age = 34.2, 82.9% female, 71% White) assessed adoption, perceived utility, clinician exposure use, and persistent barriers to exposure use. Results: In its first three years, READY had 13,543 page views across 1,731 unique users; 442 (25.6%) registered as a site user to access specialized content. Survey data suggested variability in usage and perceived utility across toolkit components. Qualitative analyses highlighted persistent exposure barriers that pointed to potential READY refinements. Conculsions: Overall, READY has been accessed by hundreds of clinicians, but its impact was limited by low return to the site. This study highlights strengths and limitations of standalone online implementation supports and identifies additional steps needed to optimally support clinicians to deliver exposure to youth in need.

Identifying Common and Unique Barriers and Facilitators to Implementing Evidence-Based Practices for Suicide Prevention across Primary Care and Specialty Mental Health Settings.

OBJECTIVE: We identified common and unique barriers and facilitators of evidence-based suicide prevention practices across primary care practices with integrated behavioral health services and specialty mental health settings to identify generalizable strategies for enhancing future implementation efforts. METHOD: Twenty-six clinicians and practice leaders from behavioral health (n = 2 programs) and primary care (n = 4 clinics) settings participated. Participation included a semi-structured qualitative interview on barriers and facilitators to implementing evidence-based suicide prevention practices. Within that interview, clinicians participated in a chart-stimulated recall exercise to gather additional information about decision making regarding suicide screening. Interview guides and qualitative coding were informed by leading frameworks in implementation science and behavioral science, and an integrated approach to interpreting qualitative results was used. RESULTS: There were a number of similar themes associated with implementation of suicide prevention practices across settings and clinician types, such as the benefits of inter-professional collaboration and uncertainties about managing suicidality once risk was disclosed. Clinicians also highlighted barriers unique to their settings. For primary care settings, time constraints and competing demands were consistently described as barriers. For specialty mental health settings, difficulties coordinating care with schools and other providers in the community made implementation of suicide prevention practices challenging. CONCLUSION: Findings can inform the development and testing of implementation strategies that are generalizable across primary care and specialty mental health settings, as well as those tailored for unique site needs, to enhance use of evidence-based suicide prevention practices in settings where individuals at risk for suicide are especially likely to present.HIGHLIGHTSWe examined barriers and facilitators to suicide prevention across health settings.Common and unique barriers and facilitators across health-care settings emerged.Findings can enhance suicide prevention implementation across health-care settings.

The Relationship Between Trauma Exposure and Obsessive-Compulsive Disorder in Youth: A Systematic Review.

Extant literature suggests a possible relationship between childhood trauma exposure and the development and trajectory of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD); however, this relationship is poorly understood. We conducted a systematic review that examined trauma exposure and OCS/OCD in youth. Primary inclusion criteria were English-language articles that addressed a sample with participants under 18 years of age. 46 articles met criteria for review, and were categorized into three groups of overlap: Post-traumatic Stress Disorder (PTSD) and OCS or OCD (n = 3), clearly defined Criterion A event trauma exposure and OCS or OCD (n = 30), and less well-defined potential trauma exposure and OCS or OCD (n = 13). There was mixed evidence linking trauma exposure and the development of OCS or OCD in youth. Major methodological limitations preclude formal conclusions. More research on co-occurring trauma exposure and OCD/OCS in youth is needed to advance research and improve treatment.

A case example of community-based supervision to overcome barriers and support the implementation of exposure therapy.

Supervision in community mental health (CMH) settings is critically important for supporting clinical competency and optimizing clinical outcomes. However, CMH supervision is hindered by numerous administrative and fiscal challenges, which makes aligning supervision practices with gold-standard recommendations notoriously difficult. This article describes a case example of one multicomponent supervision approach within a CMH clinic used to support the delivery of exposure therapy ("exposure") to youth with publicly funded insurance. We first review current recommendations for supervision and highlight the primary barriers to the use of these supervisory practices in CMH settings. We then present three low-burden supervisory approaches used to supplement traditional individual supervision. Each strategy presented aims to mitigate known barriers and maximize alignment with gold-standard supervision practices for exposure while being sustainable within a community setting. Finally, we review the strengths and limitations of each supervision strategy. The multicomponent strategies presented represent a creative approach to CMH supervision that maximizes the limited resources and infrastructure in CMH settings to support the delivery of gold-standard supervision. We conclude by offering insights into how these strategies could support supervision for a broader range of evidence-based practices (EBPs) and make recommendations for future research.

Youth Trauma Histories are Associated with Under-diagnosis and Under-treatment of Co-occurring Youth Psychiatric Symptoms.

OBJECTIVE: We examined whether in the presence of trauma exposure, non-traumatic stress-related symptoms are interpreted by mental health clinicians as less salient than the trauma exposure and are de-emphasized as a treatment target, consistent with a diagnostic overshadowing bias. METHODS: Using an adapted version of a diagnostic overshadowing bias experimental paradigm, mental health clinicians (N = 266, M age = 34.4 years, 82% female) were randomly assigned to receive two of six clinical vignette variations. Vignette 1 described an adolescent with obsessive-compulsive disorder (OCD). Vignette 2 described a pre-adolescent with oppositional defiant disorder (ODD). Vignettes were identical except for whether the youth reported exposure to a potentially traumatic event (PTE; no PTE, sexual PTE, or physical PTE). Clinicians received one vignette with a PTE and one without, counterbalancing order. Clinicians rated the likelihood the youth met criteria for various diagnoses and the appropriateness of various treatments on 7-point scales. RESULTS: Across both vignettes, clinicians rated the target diagnosis (OCD in Vignette 1, ODD in Vignette 2) as less likely for vignettes with a PTE than for the same vignettes without a PTE. Clinicians also rated evidence-based treatment modalities for target diagnoses as less appropriate in the presence of a PTE than when a PTE was present. CONCLUSIONS: Consistent with possible bias, clinicians may under-recognize and under-treat non-traumatic stress-related mental health symptoms in youth with a co-occurring trauma history. Future work to validate this bias in real-world practice is indicated.

A systematic review of brief, freely accessible, and valid self-report measures for substance use disorders and treatment.

BACKGROUND: Self-report measures can improve evidence-based assessment practices in substance use disorder treatment, but many measures are burdensome and costly, limiting their utility in community practice and non-specialty healthcare settings. This systematic review identified and evaluated the psychometric properties of brief, free, and readily accessible self-report measures of substance use and related factors. METHODS: We searched two electronic databases (PsycINFO and PubMed) in May 2021 for published literature on scales, measures, or instruments related to substance use, substance use treatment, and recovery, and extracted the names of all measures. Measures were included if they were: (1) brief (25 items or fewer), (2) freely accessible in a ready-to-use format, and (3) had published psychometric data. RESULTS: An initial search returned 411 measures, of which 73 (18%) met criteria for inclusion. Included measures assessed a variety of substances (e.g., alcohol, nicotine, opioids, cannabinoids, cocaine) and measurement domains (e.g., use, severity, expectancies, withdrawal). Among these measures, 14 (19%) were classified as psychometrically "excellent," 27 (37%) were rated as "good," 32 (44%) were "adequate." CONCLUSIONS: Despite the shift toward evidence-based assessment in substance use disorder treatment in the last twenty years, key areas of public health concern are lacking pragmatic, psychometrically valid measures. Among the brief measures we reviewed, less than a fifth met criteria for psychometric "excellence" and most of these instruments fell into one measurement domain: screening for problematic substance use. Future research should focus both on improving the evidence base for existing brief self-report measures and creating new low-burden measures for specific substances and treatment constructs.

What is the Status of Multi-Informant Treatment Fidelity Research?

OBJECTIVE: The precise measurement of treatment fidelity (quantity and quality in the delivery of treatment strategies in an intervention) is essential for intervention development, evaluation, and implementation. Various informants are used in fidelity assessment (e.g., observers, practitioners [clinicians, teachers], clients), but these informants often do not agree on ratings. This scoping review aims to ascertain the state of science around multi-informant assessment of treatment fidelity. METHOD: A literature search of articles published through December 2021 identified 673 articles. Screening reduced the number of articles to 44, and the final study set included 35 articles. RESULTS: There was substantial variability across studies regarding study design, how fidelity was operationalized, and how reliability was defined and assessed. Most studies evaluated the agreement between independent observers and practitioner-report, though several other informant pairs were assessed. Overall, findings suggest that concordance across fidelity informants was low to moderate, with a few key exceptions. CONCLUSIONS: It is difficult to draw clear conclusions about the degree to which single versus multiple informant assessment is needed to produce an accurate and complete picture of treatment fidelity. The field needs to take steps to determine how to leverage multi-informant assessment to accurately assess treatment fidelity.

Clinician Maladaptive Anxious Avoidance in the Context of Implementation of Evidence-Based Interventions: A Commentary.

This paper posits that a clinician's own anxious reaction to delivering specific evidence-based interventions (EBIs) should be better accounted for within implementation science frameworks. A key next step for implementation science is to delineate the causal processes most likely to influence successful implementation of evidence-based interventions (EBIs). This is critical for being able to develop tailored implementation strategies that specifically target mechanisms by which implementation succeeds or fails. First, we review the literature on specific EBIs that may act as negatively valenced stimuli for clinicians, leading to a process of clinician maladaptive anxious avoidance that can negatively impact EBI delivery. In the following sections, we argue that there are certain EBIs that can cause emotional distress or discomfort in a clinician, related to either: (1) a clinicians' fear of the real or predicted short-term distress the EBI can cause patients, or (2) fears that the clinician will inadvertently cause the patient harm and/or face liability. This distress experienced by the clinician can perpetuate a cycle of maladaptive anxious avoidance by the clinician, contributing to lack of or suboptimal EBI implementation. We illustrate how this cycle of maladaptive anxious avoidance can influence implementation by providing several examples from leading EBIs in the psychosocial literature. To conclude, we discuss how leveraging decades of treatment literature aimed at mitigating maladaptive anxious avoidance can inform the design of more tailored and effective implementation strategies for EBIs that are negatively valenced.

A Randomized Trial to Identify Accurate Measurement Methods for Adherence to Cognitive-Behavioral Therapy.

Clinician fidelity to cognitive behavioral therapy (CBT) is an important mechanism by which desired clinical outcomes are achieved and is an indicator of care quality. Despite its importance, there are few fidelity measurement methods that are efficient and have demonstrated reliability and validity. Using a randomized trial design, we compared three methods of assessing CBT adherence-a core component of fidelity-to direct observation, the gold standard. Clinicians recruited from 27 community mental health agencies (n = 126; M age = 37.69 years, SD = 12.84; 75.7% female) were randomized 1:1:1 to one of three fidelity conditions: self-report (n = 41), chart-stimulated recall (semistructured interviews with the chart available; n = 42), or behavioral rehearsal (simulated role-plays; n = 43). All participating clinicians completed fidelity assessments for up to three sessions with three different clients that were recruited from clinicians' caseloads (n = 288; M age = 13.39 years SD = 3.89; 41.7% female); sessions were also audio-recorded and coded for comparison to determine the most accurate method. All fidelity measures had parallel scales that yielded an adherence maximum score (i.e., the highest-rated intervention in a session), a mean of techniques observed, and a count total of observed techniques. Results of three-level mixed effects regression models indicated that behavioral rehearsal produced comparable scores to observation for all adherence scores (all ps > .01), indicating no difference between behavioral rehearsal and observation. Self-report and chart-stimulated recall overestimated adherence compared to observation (ps < .01). Overall, findings suggested that behavioral rehearsal indexed CBT adherence comparably to direct observation, the gold-standard, in pediatric populations. Behavioral rehearsal may at times be able to replace the need for resource-intensive direct observation in implementation research and practice.
