RESUMEN

Salivary gland adenoid cystic carcinoma (ACC) is a rare malignancy with limited treatment options. The development of novel therapies is hindered by a lack of preclinical models. We have generated ACC patient-derived xenograft (PDX) lines that retain the physical and genetic properties of the original tumours, including the presence of the common MYB::NFIB or MYBL1::NFIB translocations. We have developed the conditions for the generation of both 2D and 3D tumour organoid patient-derived ACC models that retain MYB expression and can be used for drug studies. Using these models, we show in vitro and in vivo sensitivity of ACC cells to the bromodomain degrader, dBET6. Molecular studies show a decrease in BRD4 and MYB protein levels and target gene expression with treatment. The most prominent effect of dBET6 on tumours in vivo was a change in the relative composition of ACC cell types expressing either myoepithelial or ductal markers. We show that dBET6 inhibits the progenitor function of ACC cells, particularly in the myoepithelial marker-expressing population, revealing a cell-type-specific sensitivity. These studies uncover a novel mechanistic effect of bromodomain inhibitors on tumours and highlight the need to impact both cell-type populations for more effective treatments in ACC patients. © 2023 The Authors.

RESUMEN

ABSTRACT: Many techniques exist to reapproximate a cleft lip but can leave unsatisfactory results with nonanatomic scars and a short upper lip, creating a need for revision. Many revisions focus on adjacent tissue transfers and realignment of landmarks, but in the senior authors' experience, recreating the defect and utilizing the Fisher repair for revision have led to aesthetically pleasing results and less noticeable scars. A database was collected that included all cleft lip revisions performed at a large, comprehensive children's hospital from October 2018 to July 2021. Inclusion criteria included any cleft patient with a cleft lip revision performed by two craniofacial surgeons. Data collected included sex, characteristics of the cleft lip, age at initial and index repair, type of initial repair, previous revisions, type of revision with any additional tissue rearrangement, and any nose repair. Sixty-five patients were included in the study for analysis. The type of initial repair was known in sixty-four cases (98%), and fifty-four were Millard repairs (83%). Twenty-two patients (33%) had a previous revision prior to their index revision. Sixty patients (92%) underwent the Fisher repair technique for their index revision and forty-six patients (70%) underwent nasal revision. In follow-up, all patients demonstrated an improvement in lip aesthetics. This study demonstrates a large subset of patients that have undergone cleft lip revision using the Fisher technique. In the senior surgeons' experience, the Fisher repair technique in the setting of cleft lip revision is an ideal way to address the shortcomings of historical repair techniques.

RESUMEN

Implementation outcomes, which focus on the barriers to, and facilitators and processes of healthcare delivery, are critical to translating research evidence to health planning and practice and to improving healthcare delivery. This article summarises key quality issues in reporting of implementation science outcomes within global health and describes the ways in which this presents a challenge for shifting health planning and practice across low-resource health systems. This article also suggests that the wider use of reporting guidelines for implementation outcomes could help address this issue.

RESUMEN

AIM: A systematic review to identify which mood and depression measures are valid for use with people with severe cognitive and communication impairments following severe acquired brain injury. METHOD: A systematic search of Cochrane, Web of Science, Ovid, and EBSCOhost was performed in March 2020, July 2021, and September 2022. The search focused on self-report and observer-rated assessment tools used to assess mood, depression, and/or distress in those described as having a severe acquired brain injury. Psychometric properties were extracted using the Consensus-based standards for the selection of health measurement instruments (COSMIN) risk of bias checklist. Qualitative synthesis was performed on extracted patient data. RESULTS: Nineteen papers detailing the psychometric properties of 25 measures were included, involving 2,914 participants. Nine papers provided details confirming the severity of participants' cognitive and communication impairments. The remaining papers described including severely injured participants but provided limited details so that precise level of severity could not be confirmed. Only one paper showed evidence of adequate psychometric properties and included those with severe cognitive impairments in a study of two observer-rated measures, the Stroke Aphasia Depression Questionnaire (10 items) and the Aphasia Depression Rating Scale. CONCLUSIONS: Due to the exclusion of individuals with severe cognitive and communication consequences following brain injury, no studies using self-report measures showed adequate validity evidence to recommend their use in this population. A small study using two observer-rated scales included those with severe cognitive impairments and showed satisfactory evidence that these measures can be validly used with this population.

RESUMEN

Animals respond to sudden challenges with a coordinated set of physiological and behavioral responses that enhance the ability to cope with stressors. While general characteristics of the vertebrate stress response are well described, it is not as clear how individual components covary between or within individuals. A rapid increase in glucocorticoids coordinates the stress response and one of the primary downstream results is an increase in glucose availability via reduced glucose utilization. Here, we asked whether between- and within-individual variation in corticosterone directly predict variation in glucose. We collected 2673 paired glucose and corticosterone measures from 776 tree swallows (Tachycineta bicolor) from four populations spanning the species range. In adults, glucose and corticosterone both increased during a standardized restraint protocol in all four populations. Moreover, in one population experimentally increasing a precursor that stimulates corticosterone release resulted in a further increase in both measures. In contrast, nestlings did not show a robust glucose response to handling or manipulation. Despite this group-level variation, there was very little evidence in any population that between-individual variation in corticosterone predicted between-individual variation in glucose regulation. Glucose was moderately repeatable within individuals, but within-individual variation in glucose and corticosterone were unrelated. Our results highlight the fact that a strong response in one aspect of the coordinated acute stress response (corticosterone) does not necessarily indicate that specific downstream components, such as glucose, will show similarly strong responses. These results have implications for understanding the evolution of integrated stress response systems.

RESUMEN

Harmful alcohol consumption can significantly compromise adherence to antiretroviral therapy (ART). Prior research has identified aggregate relationships between alcohol use and ART non-adherence, largely relying on concurrent assessment of these domains. There is relatively limited evidence on more nuanced day-level associations between alcohol use and ART non-adherence, despite potentially important clinical implications. We recruited adults with HIV treatment adherence challenges and harmful alcohol use (n = 53) from HIV care in South Africa. We examined relationships between alcohol use and same and next day ART adherence, accounting for the role of weekends/holidays and participant demographics, including gender. Results demonstrated that ART adherence was significantly worse on weekend/holiday days. Next day adherence was significantly worse in the context of weekend alcohol use and among men. These results suggest the importance of tailoring intervention strategies to support ART adherence during weekend drinking and for men engaged in heavy episodic drinking.

RESUMEN

Little is known about gender effects of alcohol and drug use (AOD) among people living with HIV (PLWH) in resource-limited settings. Using multilevel models, we tested whether gender moderated the effect of Khanya, a cognitive-behavioral therapy-based intervention addressing antiretroviral (ART) adherence and AOD reduction. We enrolled 61 participants from HIV care and examined outcomes at 3- and 6-months compared to enhanced treatment as usual (ETAU). Gender significantly moderated the effect of Khanya on ART adherence (measured using electronically-monitored and biomarker-confirmed adherence), such that women in Khanya had significantly lower ART adherence compared to men in Khanya; no gender differences were found for AOD outcomes. Exploratory trajectory analyses showed men in Khanya and both genders in ETAU had significant reductions in at least one AOD outcome; women in Khanya did not. More research is needed to understand whether a gender lens can support behavioral interventions for PLWH with AOD.Trial registry ClinicalTrials.gov identifier: NCT03529409. Trial registered on May 18, 2018.

RESUMEN

OBJECTIVE: Effective "task shared," or nonspecialist delivered, psychological interventions for children and adolescents have been developed or adapted in low- and middle-income countries with the aim of closing the global treatment gap for youth mental health care. Yet, delivery remains limited, in part due to the lack of knowledge of associated implementation, or process, outcomes. This scoping review aims to describe, examine the quality of, and synthesize findings on implementation outcomes of child and adolescent psychological interventions in low-and middle-income countries. METHODS: PubMed, Web of Science, and PsycInfo were searched for studies on child and adolescent psychological interventions in low- and middle-income countries reporting on implementation outcomes. After abstract and full-text review, data were extracted and summarized on implementation outcomes and quality of implementation outcomes reporting. Implementation barriers and recommendations for addressing barriers were also charted and narratively synthesized. RESULTS: Out of 5,207 manuscripts, 86 met inclusion criteria. Younger children were underrepresented. Studies largely reported feasibility and acceptability and did not state hypotheses or use conceptual models. Barriers primarily related to interventions being too complex, not an acceptable fit with participant cultures, and facilitators lacking time for or experiencing distress delivering interventions. Recommendations focused on increasing intervention fit and flexibility, training and support for facilitators, and linkages with existing systems. CONCLUSIONS: Rigorous, broader implementation outcomes research is needed within child and adolescent psychological intervention research in low-and middle-income countries. Current evidence suggests the importance of the further developing strategies to increase acceptability to participants and better support facilitators.

RESUMEN

Human immunodeficiency virus (HIV) and problematic alcohol use are two ongoing and interconnected epidemics in South Africa, with untreated problematic alcohol use associated with poorer HIV treatment outcomes and disease progression. A lack of trained mental health providers is a primary barrier to increasing access to evidence-based treatment in this setting. To address this gap, we integrated evidence-based intervention components for problematic alcohol use and antiretroviral therapy (ART) adherence, adapted for lay provider delivery in an HIV primary care setting in Cape Town, South Africa. The intervention, locally termed "Khanya" in isiXhosa, which means glow, direction, or light, comprises Life Steps adherence counseling, motivational interviewing, behavioral activation, and relapse prevention, including mindfulness-based relapse prevention components. In this case series, we present a detailed description of the intervention and provide three clinical cases of individuals who received the Khanya intervention to showcase necessary clinical adaptations and the supervision needed for optimal treatment delivery, flexibility in intervention delivery, and overall successes and challenges. We present descriptive data on alcohol use and ART adherence outcomes for the cases to supplement the narrative discussion. Successes of intervention delivery included participant uptake of mindfulness skills, reductions in alcohol use despite varying levels of motivation, and interventionist mastery over various clinical skills. Challenges included delivering the intervention within the allotted time and the strong influence of substance-using social networks. Overall, a pragmatic approach to intervention delivery was necessary, as was ongoing support for the interventionist to promote fidelity to both treatment components and therapeutic skills.

RESUMEN

Self-criticism is a transdiagnostic process associated with a range of psychological problems. This uncontrolled pilot study evaluated the feasibility and acceptability of a six-session intervention using methods from compassion-focused therapy to reduce self-criticism, as well as investigating changes in a range of outcome measures. Twenty-three university student participants with significant impaired functioning associated with high levels of self-criticism received six individual weekly treatment sessions and a 2-month follow-up appointment. Acceptability was assessed through participant feedback. The intervention appeared to be feasible in terms of recruitment and retention of participants, and participant feedback indicated that overall the intervention seemed acceptable. There were statistically significant improvements between pre- and post-intervention for self-criticism, functional impairment, mood, self-esteem and maladaptive perfectionism with medium to large effect sizes at both post-intervention and follow-up. Gains were maintained or increased between post-treatment and 2-month follow-up. The study showed preliminary evidence of effectiveness of a compassion-focused intervention for self-critical students which appeared to be a feasible and acceptable treatment approach. This intervention now requires investigation in a randomized controlled trial.

RESUMEN

While the ecological effects of climate change have been widely observed, most efforts to document these impacts in terrestrial systems have concentrated on the impacts of temperature. We used tree swallow (Tachycineta bicolor) nest observations from two widely separated sites in central Alaska to examine the aspects of climate affecting breeding phenology at the northern extent of this species' range. We found that two measures of breeding phenology, annual lay and hatch dates, are more strongly predicted by windiness and precipitation than by temperature. At our longest-monitored site, breeding phenology has advanced at nearly twice the rate seen in more southern populations, and these changes correspond to long-term declines in windiness. Overall, adverse spring climate conditions known to negatively impact foraging success of swallows (wet, windy weather) appear to influence breeding phenology more than variation in temperature. Separate analyses show that short windy periods significantly delay initiation of individual clutches within years. While past reviews have emphasized that increasing variability in climate conditions may create physiological and ecological challenges for natural populations, we find that long-term reductions in inclement weather corresponded to earlier reproduction in one of our study populations. To better predict climate change impacts, ecologists need to more carefully test effects of multiple climate variables, including some, like windiness, that may be of paramount importance to some species, but have rarely been considered as strong drivers of ecological responses to climate alteration.

RESUMEN

Stress is a challenge among non-specialist health workers worldwide, particularly in low-resource settings. Understanding and targeting stress is critical for supporting non-specialists and their patients, as stress negatively affects patient care. Further, stigma toward mental health and substance use conditions also impacts patient care. However, there is little information on the intersection of these factors. This sub-analysis aims to explore how substance use and mental health stigma intersect with provider stress and resource constraints to influence the care of people with HIV/TB. We conducted semi-structured interviews (N=30) with patients (n=15) and providers (n=15, non-specialist health workers) within a low-resource community in Cape Town, South Africa. Data were analyzed using thematic analysis. Three key themes were identified: (1) resource constraints negatively affect patient care and contribute to non-specialist stress; (2) in the context of stress, non-specialists are hesitant to work with patients with mental health or substance use concerns, who they view as more demanding and (3) stress contributes to provider stigma, which negatively impacts patient care. Findings highlight the need for multilevel interventions targeting both provider stress and stigma toward people with mental health and substance use concerns, especially within the context of non-specialist-delivered mental health services in low-resource settings.

RESUMEN

Intimate partners play an important role in chronic diseases. Despite the chronic disease burden increase in sub-Saharan Africa, very few culturally-relevant quantitative measures of intimate relationship functioning are available. We conducted an empirical investigation evaluating the psychometric properties of the South African Relationship Functioning Assessment (SARFA) assessing healthy relationship functioning in N = 150 community members (50% women; M age = 27.2 years) living in the Vulindlela area of KwaZulu-Natal, South Africa. Item development was based on prior qualitative research from two South African communities. All assessments were conducted in isiZulu, participants' primary language. An exploratory factor analysis was conducted on the initial 39-item measure. The best-fitting model consisted of one factor with 22 items. The SARFA's internal consistency was α = .94. Convergent validity was observed via significant positive associations (all rs ≥ .38, p < .001) between the SARFA's total score and measures of trust, emotional intimacy, constructive communication, sexual satisfaction, and relationship control (women only). Divergent validity was observed for women only. Encouraging initial psychometric properties of a culturally-relevant measure of relationship functioning in KwaZulu-Natal may have relevance to other communities and potential to be used in research involving couples and health in chronic disease-burdened communities.

RESUMEN

Global health reciprocal innovation emphasizes the movement of technologies or interventions between high- and low-income countries to address a shared public health problem, in contrast to unidirectional models of "development aid" or "reverse innovation". Evidence-based interventions are frequently adapted from the setting in which they were developed and applied in a new setting, presenting an opportunity for learning and partnership across high- and low-income contexts. However, few clear procedures exist to guide researchers and implementers on how to incorporate equitable and learning-oriented approaches into intervention adaptation across settings. We integrated theories from pedagogy, implementation science, and public health with examples from experience adapting behavioral health interventions across diverse settings to develop a procedure for a bidirectional, equitable process of intervention adaptation across high- and low-income contexts. The Mutual capacity building model for adaptation (MCB-MA) is made up of seven steps: 1) Exploring: A dialogue about the scope of the proposed adaptation and situational appraisal in the new setting; 2) Developing a shared vision: Agreeing on common goals for the adaptation; 3) Formalizing: Developing agreements around resource and data sharing; 4) Sharing complementary expertise: Group originating the intervention supporting the adapting group to learn about the intervention and develop adaptations, while gleaning new strategies for intervention implementation from the adapting group; 5) Reciprocal training: Originating and adapting groups collaborate to train the individuals who will be implementing the adapted intervention; 6) Mutual feedback: Originating and adapting groups share data and feedback on the outcomes of the adapted intervention and lessons learned; and 7) Consideration of next steps: Discuss future collaborations. This evidence-informed procedure may provide researchers with specific actions to approach the often ambiguous and challenging task of equitable partnership building. These steps can be used alongside existing intervention adaptation models, which guide the adaptation of the intervention itself.

RESUMEN

BACKGROUND: South Africa has deployed community health workers (CHWs) to support individuals to enter and stay in HIV/TB care. Although CHWs routinely encounter patients with mental health (particularly depression) and substance use (SU) conditions that impact their engagement in HIV/TB care, CHWs are rarely trained in how to work with these patients. This contributes to mental health and SU stigma among CHWs, a known barrier to patient engagement in care. Mental health and SU training interventions could reduce CHW stigma and potentially improve patient engagement in care, but evidence of the feasibility, acceptability, and preliminary effectiveness of these interventions is scarce. Therefore, we designed a hybrid type 2 effectiveness-implementation pilot trial to evaluate the implementation and preliminary effectiveness of a CHW training intervention for reducing depression and SU stigma in the Western Cape, South Africa. METHODS: This stepped wedge pilot trial will engage CHWs from six primary care clinics offering HIV/TB care. Clinics will be block randomized into three-step cohorts that receive the intervention at varying time points. The Siyakhana intervention involves 3 days of training in depression and SU focused on psychoeducation, evidence-based skills for working with patients, and self-care strategies for promoting CHW wellness. The implementation strategy involves social contact with people with lived experience of depression/SU during training (via patient videos and a peer trainer) and clinical supervision to support CHWs to practice new skills. Both implementation outcomes (acceptability, feasibility, fidelity) and preliminary effectiveness of the intervention on CHW stigma will be assessed using mixed methods at 3- and 6-month follow-up assessments. DISCUSSION: This trial will advance knowledge of the feasibility, acceptability, and preliminary effectiveness of a CHW training for reducing depression and SU stigma towards patients with HIV and/or TB. Study findings will inform a larger implementation trial to evaluate the longer-term implementation and effectiveness of this intervention for reducing CHW stigma towards patients with depression and SU and improving patient engagement in HIV/TB care.

RESUMEN

South Africa has one of the highest rates of HIV/tuberculosis (TB) co-infection, and poor engagement in HIV/TB care contributes to morbidity and mortality. In South Africa, community health workers (CHWs) are tasked with re-engaging patients who have dropped out of HIV/TB care. CHWs have described substantial challenges with substance use (SU) and depression among their patients, while patients have described CHW stigma towards SU and depression as barriers to re-engagement in care. Yet, CHWs receive little-to-no training on SU or depression. Therefore, we piloted Siyakhana, a brief CHW training to reduce stigma related to SU and depression while improving skills for re-engaging these patients in HIV and/or TB care. This study evaluated the preliminary effectiveness (stigma towards SU and depression; clinical competence assessed via roleplay) and implementation (quantitative ratings of feasibility, acceptability, appropriateness, adoption; semi-structured written qualitative feedback) of Siyakhana among CHWs and supervisors (N = 17) at pre- and post-training assessments. SU stigma significantly decreased (F(1,16) = 18.94, p < 0.001, ηp2 = 0.54). Depression stigma was lower than SU stigma at both timepoints and did not significantly decrease after training. CHW clinical competency towards patients with SU/depression significantly improved (t(11) = -3.35, p = 0.007, d = 1.00). The training was rated as feasible, acceptable, appropriate, and likely to be adopted by CHWs and their supervisors. Nonjudgmental communication was commonly described as the most useful training component. Based on this pilot, the training is being refined and evaluated in a larger randomized stepped-wedge clinical trial.

RESUMEN

Introduction: In South Africa (SA), community-oriented primary care (COPC) teams work to re-engage out-of-care people with HIV (PWH) in treatment, many of whom have substance use (SU) concerns. SU stigma is high among these teams, limiting care engagement efforts. Integrating peer recovery coaches (PRCs) into COPC teams could shift SU stigma and improve patients' engagement in care. The PRC role does not exist in SA and represents a workforce innovation. To enhance acceptability, feasibility, and appropriateness for the local context, we engaged multiple stakeholder groups to co-design a PRC role for COPC team integration. Methods: We used a five-step human-centered design process: (i) semi-structured interviews with healthcare worker (HCW, n = 25) and patient (n = 15) stakeholders to identify priorities for the role; (ii) development of an initial role overview; (iii) six ideation workshops with HCW (n = 12) and patient (n = 12) stakeholders to adapt this overview; (iv) refinement of the role prototype via four co-design workshops with HCW (n = 7) and patient (n = 9) stakeholders; and (v) consultation with HIV and SU service leaders to assess the acceptability and feasibility of integrating this prototype into COPC teams. Results: Although all stakeholders viewed the PRC role as acceptable, patients and HCWs identified different priorities. Patients prioritized the care experience through sharing of lived experience and confidential SU support. HCWs prioritized clarification of the PRC role, working conditions, and processes to limit any impact on the COPC team. A personal history of SU, minimum 1 year in SU recovery, and strong community knowledge were considered role prerequisites by all stakeholders. Through the iterative process, stakeholders clarified their preferences for PRC session structure, location, and content and expanded proposed components of PRC training to include therapeutic and professional work practice competencies. Service leaders endorsed the prototype after the addition of PRC integration training for COPCs and PRC mentoring to address community and COPC dynamics. Conclusion: Stakeholder engagement in an iterative HCD process has been integral to co-designing a PRC role that multiple stakeholder groups consider acceptable and that COPC teams are willing to implement. This offers a methodological framework for other teams designing SU workforce innovations.

RESUMEN

Explaining latitudinal patterns in life history traits remains a challenge for ecologists and evolutionary biologists. One such prominent pattern is the latitudinal gradient in clutch size in birds: the number of eggs laid in a reproductive bout increases with latitude in many species. One intuitive hypothesis proposes that the longer days at high latitudes during the breeding season allow parents to spend more time foraging each day, which results in greater total food delivery to the brood each day, and hence more offspring produced. This day length hypothesis is virtually untested, although it was proposed nearly 100 years ago. We developed a conceptual framework for distinguishing between the day length hypothesis and the widely accepted alternative hypothesis that attributes the latitudinal gradient in clutch size to increased per capita food resources at higher latitudes. Using this framework to contrast components of reproductive effort and life history patterns in a mid- and high-latitude Tree Swallow (Tachycineta bicolor) population provided clear evidence for the day length hypothesis, but little evidence for the alternative. Our findings suggest that the length of an animal's workday may be an important, but unappreciated, component of reproductive effort.

RESUMEN

OBJECTIVE: Task-shared delivery of mental health care, which includes training people who are not mental health specialists to deliver components of care, has been identified as a core strategy for increasing access to mental health care globally. However, after standard training, nonspecialists attain variable and sometimes poor competence in task-shared mental health care. This study examined whether pretraining interpersonal skills (nonverbal communication, verbal communication, rapport building, and empathy-warmth) are related to posttraining competence in task-shared mental health care among nonspecialists in Nepal. METHODS: Nonspecialists (e.g., auxiliary health workers and health assistants) (N=185) were assessed at pretraining and posttraining (4 months after training and supervision) in a task-shared mental health care program in Nepal. This study employed both a classification algorithm and a logistic regression model to examine the relationship between pretraining interpersonal skills and posttraining competence. RESULTS: The classification model predicted posttraining competence at above-chance levels on the basis of pretraining interpersonal skills. In particular, pretraining nonverbal communication skill distinguished participants whose posttraining competence was rated as acceptable from those whose rating was not acceptable. Nonverbal communication was also a significant predictor in the regression model. No other interpersonal skills were significantly related to posttraining competence outcomes in the regression model. CONCLUSIONS: Some pretraining interpersonal skills of nonspecialists may predict overall competence outcomes in task-shared mental health care. Future studies confirming the relationship between pretraining interpersonal skills and posttraining competence in care delivery could improve staff selection and training strategies in task-shared mental health care programs.

RESUMEN

BACKGROUND: The peer recovery specialist (PRS) workforce has rapidly expanded to increase access to substance-use disorder services for underserved communities. PRSs are not typically trained in evidence-based interventions (EBIs) outside of motivational interviewing, although evidence demonstrates the feasibility of PRS delivery of certain EBIs, such as a brief behavioral intervention, behavioral activation. However, characteristics that predict PRS competency in delivering EBIs such as behavioral activation remain unknown, and are critical for PRS selection, training, and supervision if the PRS role is expanded. This study aimed to explore the outcomes of a brief PRS training period in behavioral activation and identify predictors of competence. METHOD: Twenty PRSs in the United States completed a two-hour training on PRS-delivered behavioral activation. Participants completed baseline and post-training assessments, including roleplay and assessments of PRS characteristics, attitudes towards EBIs, and theoretically relevant personality constructs. Roleplays were coded for competence (behavioral activation specific and PRS skills more broadly, i.e., PRS competence) and changes were assessed from baseline to post-training. Linear regression models tested factors predicting post-training competence, controlling for baseline competence. RESULTS: There was a significant pre-post increase in behavioral activation competence (t = -7.02, p < 0.001). Years working as a PRS significantly predicted post-training behavioral activation skills (B = 0.16, p = 0.005). No variables predicted post-training PRS competence. CONCLUSIONS: This study provides preliminary evidence that behavioral activation may be appropriate for dissemination to PRSs through brief trainings, particularly for PRSs with more work experience. However, additional research is needed to examine predictors of competence among PRSs.
