Deliberate Practice and Proposed Limits on the Effects of Practice on the Acquisition of Expert Performance: Why the Original Definition Matters and Recommendations for Future Research

Improving forensic examiner decision-making through deliberate practice

Forensic examiners make important decisions to address legal questions, yet there is now ample evidence that their decisions can be subjective and inconsistent. This commentary suggests that elements of deliberate practice may help in not only having more consistent forensic decisions but also toward expected accuracy. Specifically, four elements of deliberate practice: (1) setting a goal, (2) motivation, (3) feedback, and (4) repetition are outlined with examples for addressing issues of cognitive bias and managing stress at work. If any of these elements are missing, such as delayed or no feedback, then suboptimal or no improvement of examiners' decision-making may result. This tool for deliberately improving decision-making may be applicable to other legal professionals; thus, potentially driving policies that may help enhance the criminal justice system broadly.

Development and validation of metrics for assessment of ultrasound-guided fascial block skills☆

BACKGROUND

As few anaesthetists provide lumbar erector spinae block for disc surgery, there is a need to provide training to enable a randomised controlled trial investigating analgesia after painful spinal surgery (NIHR153170). The primary objective of the study was to develop and measure the construct validity of a checklist for assessment of skills in performing lumbar and thoracic erector spinae fascial plane injection using soft-embalmed Thiel cadavers.

METHODS

Twenty-four UK consultant regional anaesthetists completed two iterations of a Delphi questionnaire. The final checklist consisted of 11 steps conducive to best practice. Thereafter, we validated the checklist by comparing the performance of 12 experts with 12 novices, each performing lumbar and thoracic erector spinae plane injections or fascia iliaca, serrato-pectoral (PEC II) and serratus injections, randomly allocated to the left and right sides of six soft-embalmed Thiel cadavers. Six expert, trained raters blinded to operator and site of block examined 120 videos each.

RESULTS

The mean (95% confidence interval) internal consistency of the 11-item checklist for erector spinae plane injection was 0.72 (0.63-0.79) and interclass correlation was 0.88 (0.82-0.93). The checklist showed construct validity for lumbar and thoracic erector spinae injection, experts vs novices {median (interquartile range [range]) 8.0 (7.0-10.0 [1-11]) vs 7.0 (5.0-9.0 [4-11]), difference 1.5 (1.0-2.5), P<0.001}. Global rating scales showed construct validity for lumbar and thoracic erector spinae injection, 28.0 (24.0-31.0 [7-35]) vs 21.0 (17.0-24.0 [7-35]), difference 7.5 (6.0-8.5), P<0.001. The most difficult items to perform were identifying the needle tip before advancing and always visualising the needle tip. Instrument handling and flow of procedure were the areas of greatest difficulty on the global rating scale (GRS). Checklists and GRS scores correlated. There was homogeneity of regression slopes controlling for status, type of injection, and rater. Generalisability analysis showed a high reliability using the checklist and GRS for all fascial plane blocks (Rho [ρ2] 0.93-0.96: Phi [ϕ] 0.84-0.87).

CONCLUSIONS

An 11-point checklist developed through a modified Delphi process to provide best practice guidance for fascial plane injection showed construct validity in performing lumbar and thoracic erector spinae fascial plane injection in soft-embalmed Thiel cadavers.

Attaining expertise in regional anaesthesia training using a multifactorial approach incorporating deliberate practice

The most effective way of delivering regional anaesthesia training and the best means of demonstrating competency have not been established. Clinical competency, based on the Dreyfus and Dreyfus lexicon, appears unachievable using current training approaches. Lessons should be taken from the worlds of music, chess, and sports. Modern skills training programmes should be built on an explicit and detailed understanding with measurement of a variety of factors such as perception, attention, psychomotor and visuospatial function, and kinesthetics, coupled with quantitative, accurate, and reliable measurement of performance.

Teaching Clinical Reasoning in the Preclinical Period

INTRODUCTION

Developing the clinical reasoning skills necessary to becoming an astute diagnostician is essential for medical students. While some medical schools offer longitudinal opportunities for students to practice clinical reasoning during the preclinical curriculum, there remains a paucity of literature fully describing what that curriculum looks like. As a result, medical educators struggle to know what an effective clinical reasoning curriculum should look like, how it should be delivered, how it should be assessed, or what faculty development is necessary to be successful. We present our Introduction to Clinical Reasoning course that is offered throughout the preclinical curriculum of the Uniformed Services University of the Health Sciences. The course introduces clinical reasoning through interactive lectures and 28 case-based small group activities over 15 months.The curriculum is grounded in script theory with a focus on diagnostic reasoning. Specific emphasis is placed on building the student's semantic competence, constructing problem lists, comparing and contrasting similar diagnoses, constructing a summary statement, and formulating a prioritized differential diagnosis the student can defend. Several complementary methods of assessment are utilized across the curriculum. These include assessments of participation, knowledge, and application. The course leverages clinical faculty, graduate medical education trainees, and senior medical students as small group facilitators. Feedback from students and faculty consistently identifies the course as a highly effective and engaging way to teach clinical reasoning.

CONCLUSION

Our Introduction to Clinical Reasoning course offers students repeated exposure to well-selected cases to promote their development of clinical reasoning. The course is an example of how clinical reasoning can be taught across the preclinical curriculum without extensive faculty training in medical education or clinical reasoning theory. The course can be adapted into different instructional formats to cover a variety of topics to provide the early learner with sequential exposure and practice in diagnostic reasoning.

Optimizing young tennis players' development: Exploring the impact of emerging technologies on training effectiveness and technical skills acquisition

The research analyzed the effect of weekly training plans, physical training frequency, AI-powered coaching systems, virtual reality (VR) training environments, wearable sensors on developing technical tennis skills, with and personalized learning as a mediator. It adopted a quantitative survey method, using primary data from 374 young tennis players. The model fitness was evaluated using confirmatory factor analysis (CFA), while the hypotheses were evaluated using structural equation modeling (SEM). The model fitness was confirmed through CFA, demonstrating high fit indices: CFI = 0.924, TLI = 0.913, IFI = 0.924, RMSEA = 0.057, and SRMR = 0.041, indicating a robust model fit. Hypotheses testing revealed that physical training frequency (β = 0.198, p = 0.000), AI-powered coaching systems (β = 0.349, p = 0.000), virtual reality training environments (β = 0.476, p = 0.000), and wearable sensors (β = 0.171, p = 0.000) significantly influenced technical skills acquisition. In contrast, the weekly training plan (β = 0.024, p = 0.834) and personalized learning (β = -0.045, p = 0.81) did not have a significant effect. Mediation analysis revealed that personalized learning was not a significant mediator between training methods/technologies and acquiring technical abilities. The results revealed that physical training frequency, AI-powered coaching systems, virtual reality training environments, and wearable sensors significantly influenced technical skills acquisition. However, personalized learning did not have a significant mediation effect. The study recommended that young tennis players' organizations and stakeholders consider investing in emerging technologies and training methods. Effective training should be given to coaches on effectively integrating emerging technologies into coaching regimens and practices.

Clinical educator expertise: A scoping review

BACKGROUND

Allied health clinicians supervising healthcare students in workplace learning play a key role in a learner's progression to autonomous practice, yet expert educator practice is not well understood. How expert clinical educators in allied health professions are defined, enact their role, develop educational expertise and bring value to workplace learning is unclear.

METHODS

A scoping methodology was chosen to understand what is known about clinical educator expertise in allied health, focusing on definitions, characteristics, impacts and development. Searching seven databases, the authors used an iterative, systematic approach to the selection, collation and analysis of peer-reviewed and grey literature.

RESULTS

Within 21 included papers, diverse terms and definitions were used to describe expert clinical educators across 9 allied health professions and 5 countries. Expert educator characteristics included advanced skills in facilitating learning, the ability to build positive relationships with learners and a proactive attitude to developing personal supervision skills through reflection. Impacts were identified for learners and educators, and the few sources examining educator development found that expert practice grows in a dynamic, multi-mode, non-linear fashion.

CONCLUSION

A comprehensive picture of the expert clinical educator in allied health is not yet conceptualised, despite some characteristics being associated with expertise. The differences between expert and less proficient educators are unclear with little examination of the impacts, value or development of expert educator capabilities. We offer a framework for future research and advocate for focused studies that examine clinical educator expertise, to enhance approaches to professional development and recognition of excellence in clinical educator practice.

From Novice to Expert: How Expertise Shapes Motor Variability in Sports Biomechanics-a Scoping Review

With expertise, athletes develop motor strategies that enhance sports performance or reduce functional costs. Motor variability is known as a relevant way to characterize these strategies in athletes with different levels of expertise. The aim of this scoping review is to gather and discuss the latest advances in the impact of expertise on motor variability during sports-related tasks. A search encompassing three databases, Medline, SportDiscus, and Academic Search Complete, was performed. Our research methodology included three core themes: motor variability, laboratory instruments, and sports. Motor variability metrics (e.g., standard deviation and approximate entropy) and laboratory instruments (e.g., motion capture system, EMG, and force plate) were compiled. Athletes' expertise was defined by the time of deliberate practice, the performance results, or the level in which they performed. Overall, 48 of the 59 included studies determined that higher-skilled athletes had lesser motor variability than lower-skilled athletes. This difference in motor variability between skill levels was present within individual athletes (intra-individual) and between athletes (inter-individual). This result was independent of the criteria used to define expertise, the type of instrumentation used, and the metrics used to quantify motor variability.

Comparing resident operative volumes for routine general surgery cases at academic, urban community, and rural training sites

BACKGROUND

Surgical training traditionally took place at academic centres, but changed to incorporate community and rural hospitals. As little data exist comparing resident case volumes between these locations, the objective of this study was to determine variations in these volumes for routine general surgery procedures.

METHODS

We analyzed senior resident case logs from 2009 to 2019 from a general surgery residency program. We classified training centres as academic, community, and rural. Cases included appendectomy, cholecystectomy, hernia repair, bowel resection, adhesiolysis, and stoma formation or reversal. We matched procedures to blocks based on date of case and compared groups using a Poisson mixed-methods model and 95% confidence intervals (CIs).

RESULTS

We included 85 residents and 28 532 cases. Postgraduate year (PGY) 3 residents at academic sites performed 10.9 (95% CI 10.1-11.6) cases per block, which was fewer than 14.7 (95% CI 13.6-15.9) at community and 15.3 (95% CI 14.2-16.5) at rural sites. Fourth-year residents (PGY4) showed a greater difference, with academic residents performing 8.7 (95% CI 8.0-9.3) cases per block compared with 23.7 (95% CI 22.1-25.4) in the community and 25.6 (95% CI 23.6-27.9) at rural sites. This difference continued in PGY5, with academic residents performing 8.3 (95% CI 7.3-9.3) cases per block, compared with 18.9 (95% CI 16.8-21.0) in the community and 14.5 (95% CI 7.0-21.9) at rural sites.

CONCLUSION

Senior residents performed fewer routine cases at academic sites than in community and rural centres. Programs can use these data to optimize scheduling for struggling residents who require exposure to routine cases, and help residents complete the requirements of a Competence by Design curriculum.

About the Predictive Value of a 3D Multiple Object Tracking Device for Talent Identification in Elite Ice Hockey Players

Purpose: The aim of this study is to verify if a single session on the NeuroTracker has predictive value in talent identification in ice hockey. Methods: Thirty-five male ice hockey players (aged 16-20) from the highest Canadian competition level for that age group participated in the study. A battery of tests (attention, working memory, time reproduction, pattern recognition, temporal equivalence, technical ability, and decision-making) was administered to verify the relation between various cognitive abilities, on-ice performance, and the baseline score on the NeuroTracker, which is claimed to solicit multiple cognitive functions. On-ice performance indicators were game-related statistics: games played, points (mean per game), on-ice goals differential, and draft rank. Results: Results show that the baseline score on the NeuroTracker is not associated with draft ranking, nor is it able to predict which players will perform best based on game-related statistics. However, the NeuroTracker baseline score does correlate with various tests involving working memory and attention. Conclusion: Currently, NeuroTracker is not specific enough to allow talent identification among same-level elite athletes in ice hockey.

Vade Mecum in ERCP, a roadmap to success: Tips from experts for excelling in ERCP

Background and study aims Training in endoscopic retrograde cholangiopancreatography (ERCP) is operator-dependent and traditionally, the apprenticeship model, in which experts are considered to be role models, has been adopted for it. The aim of this study was to develop a practical guide compiling tips from experts to help guide trainees to succeed in ERCP. Methods A web-based survey was created to understand the professional development of ERCP experts, the investments they made, the obstacles they overcame, and the quotes that guided their professional life. ERCP experts worldwide were invited to participate. Results Fifty-three experts (of 71; 74.6%) from 24 countries answered the survey. Experts started ERCP training early (average age 31 years; range, 24-52 years) and it often was combined with training for endoscopic ultrasound. A long training period (average 21 months; range, 3-120 months) was needed to achieve competence, frequently in another department, and it was commonly complemented with research in the field (76.5%). "Time and practice" were the most worthwhile investments they made to achieve success. "Sports" were an area outside endoscopy frequently considered to be important to acquire the skills necessary to excel in ERCP. "Lack of dedicated time for training" and "peer competition" were the biggest obstacles the experts faced. Several pieces of advice were given to the experts, such as to be resilient, careful, patient, responsible, and hard-working. "Personal life" was mentioned as an undeniably crucial factor for achieving long-term success that should not be forgotten. Conclusions This survey is the first to provide insight regarding the professional trajectory of renowned ERCP experts worldwide, providing valuable recommendations to help trainees excel in ERCP.

Amick and Schrepel comment on the value of incorporating assertiveness into best practices for inter‐physician communication and conflict mitigation.

Training students to become responsive therapists: implications from a sequential mixed-methods study on situations that therapists find challenging

OBJECTIVE

To draw implications for training of therapist responsiveness from a sequential mixed-methods study on challenging clinical situations.

METHOD

Study 1: online survey mapping frequency and perceived difficulty of 15 clinical situations in a representative sample of psychologists. Study 2: online survey mapping frequency and perceived difficulty of 19 clinical situations among therapists in child and adolescent psychiatry. Study 3: focus group study exploring the situations identified through study 1 and 2.

RESULTS

Study 1 and 2 showed that ratings of each situation varied between individuals and context. Study 3 showed that the degree to which a situation was challenging was described as depending on the characteristics of the therapist and the context. Experientially, challenging situations were characterized by lacking access to necessary information, falling short, and disturbing arousal. Perceiving therapeutic opportunities despite the challenging nature of the situation, collegial support, self-knowledge, and engagement were important resources.

CONCLUSION

Six implications of the results from the three studies for training of responsiveness are discussed: (1) building self-awareness and conceptualization skills; (2) personalizing training; (3) transforming disturbing arousal into engagement; (4) being exposed to a broad range of clinical situations; (5) training on commonly encountered situations; and (6) building tolerance for uncertainty and capacity to seek support.

Attracting and developing STEMM talent toward excellence and innovation

This article provides an overview of science, technology, engineering, mathematics, and medical sciences (STEMM) talent development from first exposure to a STEMM domain to achieving eminence and innovation. To this end, a resource-oriented model of STEMM talent development is proposed as a framework. It includes a three-stage phase model based on Bloom (1985), with the main focus on interest development in the first stage, skill acquisition toward expertise and excellence in the second stage, and style formation toward eminence and innovation in the final stage. A literature review shows that from an educational perspective, each phase is mainly characterized by the focus that Bloom postulated. However, it is important that all three stages (i.e., interest development, skill acquisition, and style formation) occur in a stage-typical manner. To explain how these primary objectives of STEMM development can be supported through STEMM talent education, Ziegler and Stoeger's (2011) educational and learning capital framework is used in the proposed resource-based model. A literature review shows that consistent provisioning of the resources specified in the model is necessary for individuals to complete a learning pathway to STEMM eminence and innovation.

Variation vs. specialization: the dose-time-effect of technical and physiological variety in the development of elite swimmers

OBJECTIVE

It is heavily discussed whether larger variety or specialization benefit elite performance at peak age. Therefore, this study aimed to determine technical (number of different swimming strokes) and physiological (number of different race distances) variety required to become an international-class swimmer (> 750 swimming points) based on 1'522'803 race results.

RESULTS

Correlation analyses showed lower technical variety in higher ranked swimmers (P < 0.001), yet with small effects (0.11-0.30). However, Poisson distribution revealed dose-time-effects and specified number of swimming strokes required during each age group. Specifically, freestyle swimmers showed highest chances when starting to compete in three to four swimming strokes but reduced their variety to three swimming strokes at the ages of 12/13yrs with another transition to two swimming strokes at the ages of 19/21yrs (female/male swimmers, respectively). Although both sexes showed similar specialization pattern throughout their career, earlier specialization was generally evident in female compared to male swimmers. At peak performance age, freestyle was most frequently combined with butterfly. Swimmers who either kept competing in all five swimming strokes or focused on only one at the beginning of their careers showed lowest probability of becoming an international-class swimmer. Physiological variety increased during junior age but declined again to three race distances towards elite age.

Assessing clinical reasoning skills following a virtual patient dizziness curriculum

OBJECTIVES

Dizziness is a common medical symptom that is frequently misdiagnosed. While virtual patient (VP) education has been shown to improve diagnostic accuracy for dizziness as assessed by VPs, trainee performance has not been assessed on human subjects. The study aimed to assess whether internal medicine (IM) interns after training on a VP-based dizziness curriculum using a deliberate practice framework would demonstrate improved clinical reasoning when assessed in an objective structured clinical examination (OSCE).

METHODS

All available interns volunteered and were randomized 2:1 to intervention (VP education) vs. control (standard clinical teaching) groups. This quasi-experimental study was conducted at one academic medical center from January to May 2021. Both groups completed pre-posttest VP case assessments (scored as correct diagnosis across six VP cases) and participated in an OSCE done 6 weeks later. The OSCEs were recorded and assessed using a rubric that was systematically developed and validated.

RESULTS

Out of 21 available interns, 20 participated. Between intervention (n=13) and control (n=7), mean pretest VP diagnostic accuracy scores did not differ; the posttest VP scores improved for the intervention group (3.5 [SD 1.3] vs. 1.6 [SD 0.8], p=0.007). On the OSCE, the means scores were higher in the intervention (n=11) compared to control group (n=4) for physical exam (8.4 [SD 4.6] vs. 3.9 [SD 4.0], p=0.003) and total rubric score (43.4 [SD 12.2] vs. 32.6 [SD 11.3], p=0.04).

CONCLUSIONS

The VP-based dizziness curriculum resulted in improved diagnostic accuracy among IM interns with enhanced physical exam skills retained at 6 weeks post-intervention.

Postgraduate Operating Room Nursing Students' Experiences with Blended Learning Combining Digital Learning Paths and Basic Skills Training as Preparation for Internship: A Qualitative Study

Introduction

Numerous pedagogical practices ought to be contemplated for the acquisition of practical aptitudes imperative to postgraduate operating room nursing education. The employment of digital technologies has emerged as a strategic focus in higher education and learning paths exhibit potential as a digital approach in nursing education.

Objective

This study aimed to investigate the experiences of postgraduate OR nursing students who underwent a blended learning approach, which combines digital learning paths with skills training, and to explore how this approach prepares students to attain specific learning outcomes during their internship period.

Methods

This qualitative study employed a descriptive, exploratory design and utilized focus group interviews facilitated by an interview guide to gather qualitative data. A purposive sampling strategy was employed, and the collected data were analyzed using a systematic text condensation approach.

Results

The analysis of the data revealed two main categories and five subgroups. The first category, "Blended learning serves as adequate preparation for internship," includes subgroups that highlight the advantages of diverse learning activities that aid in the development of a strong foundation in practical skills. The positive influence of peer collaboration fosters improved learning through social interaction, while the organization of the curriculum has a significant impact on students' learning experiences. The second category, "The importance of skills training and behaving in an operating theater context," consists of subgroups that emphasize the necessity of progressing from basic technical skills training to simulation pedagogy to ensure appropriate behavior in the operating room. Small group sizes, close monitoring, and assessment by educators contribute to effective learning.

Conclusion

The integration of digital learning paths with skills training fosters a problem-solving approach and encourages active and collaborative learning. Skills training in small groups, timely feedback, and coordination among subject managers to handle the students' workload can create an optimal learning environment.

An Update Summary on the Learning Sciences Within an Ophthalmic Context

Clinical reasoning, specifically diagnostic decision-making, has been a subject of fragmented literature since the 1970s, marked by diverse theories and conflicting perspectives. This article reviews the latest evidence in medical education, drawing from scientific literature, to offer ophthalmologists insights into optimal strategies for personal learning and the education of others. It explores the historical development of clinical reasoning theories, emphasising the challenges in understanding how doctors formulate diagnoses. The importance of clinical reasoning is underscored by its role in making accurate diagnoses and preventing diagnostic errors. The article delves into the dual process theory, distinguishing between type 1 and type 2 thinking and their implications for clinical decision-making. Cognitive load theory is introduced as a crucial aspect, highlighting the limited capacity of working memory and its impact on the diagnostic process. The zone of proximal development (ZPD) is explored as a framework for optimal learning environments, emphasising the importance of scaffolding and deliberate practice in skill development. The article discusses semantic competence, mental representation, and the interplay of different memory stores-semantic, episodic, and procedural-in enhancing diagnostic proficiency. Self-regulated learning (SRL) is introduced as a student-centric approach, emphasising goal setting, metacognition, and continuous improvement. Practical advice is provided for minimising cognitive errors in clinical reasoning, applying dual process theory, and considering cognitive load theory in teaching. The relevance of deliberate practice in ophthalmology, especially in a rapidly evolving field, is emphasised for continuous learning and staying updated with advancements. The article concludes by highlighting the importance of clinical supervisors in recognising and supporting trainees' self-regulated learning and understanding the principles of various teaching and learning theories. Ultimately, a profound comprehension of the science behind clinical reasoning is deemed fundamental for ophthalmologists to deliver high-quality, evidence-based care and foster critical thinking skills in the dynamic landscape of ophthalmology.

A digital exercise and augmented reality training system improved mobility among stroke patients: A randomized control trial

BACKGROUND

The Selfit system was developed to improve the mobility and gait-related functions of stroke patients by providing digital exercises and augmented reality training system.

OBJECTIVE

To evaluate the effects of a digital exercise and augmented reality training system on mobility, gait-related functions and self-efficacy outcomes in stroke patients.

METHODS

A randomized control trial was conducted on 25 men and women diagnosed with an early sub-acute stroke. Patients were randomly assigned to either the intervention (N= 11) or the control groups (N= 14). Patients in the intervention group received a digital exercise and augmented reality training using the Selfit system in addition to the standard physical therapy treatment. Patients in the control group were treated with a conventional physical therapy program. Timed Up and Go (TUG) test, 10-meter walk test, the Dynamic Gait Index (DGI), and the Activity-specific Balance Confidence (ABC) scale were completed before and after the intervention. Feasibility and satisfaction among patients and therapists were also assessed after the completion of the study.

RESULTS

The intervention group practiced proportionally more time per session than the control group with a mean change of 19.7% following 6 sessions (p= 0.002). The intervention group showed better improvement in post-TUG score compared to the control group (p= 0.04). ABC, DGI, and the 10-meter walk test scores were not significantly different between the groups. Both therapists and participants demonstrated high satisfaction with the Selfit system.

CONCLUSION

The findings suggest that Selfit holds promise as an effective intervention for improving mobility and gait-related functions among patients with an early sub-acute stroke as compared to conventional physical therapy treatments.

Pathologists aren't pigeons: exploring the neural basis of visual recognition and perceptual expertise in pathology

Visual (perceptual) reasoning is a critical skill in many medical specialties, including pathology, diagnostic imaging, and dermatology. However, in an ever-compressed medical curriculum, learning and practicing this skill can be challenging. Previous studies (including work with pigeons) have suggested that using reward-feedback-based activities, novices can gain expert levels of visual diagnostic accuracy in shortened training times. But is this level of diagnostic accuracy a result of image recognition (categorization) or is it the acquisition of diagnostic expertise? To answer this, the authors measured electroencephalographic data (EEG) and two components of the human event-related brain potential (reward positivity and N170) to explore the nature of visual expertise in a novice-expert study in pathology visual diagnosis. It was found that the amplitude of the reward positivity decreased with learning in novices (suggesting a decrease in reliance on feedback, as in other studies). However, this signal remained significantly different from the experts whose reward positivity signal did not change over the course of the experiment. There were no changes in the amplitude of the N170 (a reported neural marker of visual expertise) in novices over time. Novice N170 signals remained statistically and significantly lower in amplitude compared to experts throughout task performance. These data suggest that, while novices gained the ability to recognize (categorize) pathologies through reinforcement learning as quantified by the change in reward positivity, increased accuracy, and decreased time for responses, there was little change in the neural marker associated with visual expertise (N170). This is consistent with the multi-dimensional and complex nature of visual expertise and provides insight into future training programs for novices to bridge the expertise gap.

Examining the Talent Selection Determinants of Ultimate Frisbee Players Selected Into a National Youth Team

PURPOSE

The purpose of the study was to examine whether various athletic performances, anthropometric measures, and playing experience differentiate selected and nonselected ultimate Frisbee players trialing to compete in the world championship.

METHODS

Forty-three Australian male ultimate Frisbee players (age = 21.2 [1.2] y; height = 1.7 [6.8] m; body mass = 69.7 [8.2] kg; playing experience = 3.5 [1.5] y) participated in a 30-m sprint test, single-leg run-up jump approach (both left [JumpLL], and right leg [JumpRL]) and a stationary bilateral vertical jump (JumpBIL), and change-of-direction speed test. Following a selection camp, players were subdivided according to their selection or nonselection into the team.

RESULTS

A multivariate analysis of variance revealed that height, 10-m sprint time, acceleration, JumpLL, JumpRL, and JumpBIL were significantly greater for selected players than nonselected players (P < .05). Area under the curve (AUC) was greatest for JumpRL (AUC = 79%; optimal cutoff value of 37.5 cm, sensitivity and specificity values of 77% and 71%, respectively), JumpLL (AUC = 74%; optimal cutoff 38.5 cm, sensitivity and specificity values 77% and 77%, respectively), and JumpBIL (AUC = 78%; optimal cutoff value of 40.5 cm, sensitivity and specificity values 71% and 79%, respectively). The largest AUC (AUC = 81%; 95% CI 0.66-0.97; P = .001) was found when combining the explanatory variables that demonstrated moderate to large effect sizes (ie, height, playing experience, 10-m sprint, acceleration, JumpLL, JumpRL, and JumpBIL), with sensitivity of 93% and specificity of 71%.

CONCLUSION

These athletic performance and anthropometric characteristics differentiating selected and nonselected players may help inform targeted training and player-development strategies.

How Green Transformational Leadership Affects Employee Individual Green Performance-A Multilevel Moderated Mediation Model

Rapid economic growth puts the natural environment under tremendous pressure. As a traditional chemical company, it is important to reconsider outdated business development models, develop innovative green initiatives for long-term growth, and choose approaches to address environmental issues. Determining how to encourage employees' green performance while balancing environmental issues is crucial for chemical companies in the current social and economic environment. This study investigates the green transformational leadership style to enhance green performance of chemical company employees. It expands the field of environmental protection by employing two novel constructs: creative process engagement and green creativity. We collected 623 valid questionnaires from 98 teams (98 leaders and 525 employees) and used SPSS 26.0, HLM 6.0, and MPlus 8.3 to test the hypothesis. The findings revealed that (1) green transformational leadership positively influences individual green performance, (2) creative process engagement and green creativity mediate the relationship between green transformational leadership and individual green performance, and (3) individual environmental awareness positively moderates the relationship between green transformational leadership and green creativity. These novel findings contribute to the environmental literature and help chemical company managers in enhancing employee innovation and performance.

Investigating How Preregistrant Pharmacists Respond in Job Interviews

OBJECTIVE

To investigate what competencies and attributes preregistrant pharmacists draw upon in job interviews.

METHODS

We used a virtual mock job interview assessment asking preregistrant pharmacists to apply for an entry-level pharmacist position. Data were analyzed using a team-based framework analysis using an inductive and deductive approach and mapping responses to the National Competency Standards.

RESULTS

A total of 143 interview transcripts were included in the analysis. The top skills mentioned were leadership of self (98.6%) and communication and collaboration (96.5%). Despite graduating from a course with an integrated research curriculum, participants rarely reflected on research skills (31.5%) and no participant discussed any expertise in clinical topics or knowledge of specific professional services. Responses generally lacked specific skills and skills were spoken about broadly without relating to evidence/experience and were often not targeted to the job description. A proposal for educators aligned with competency standards was also developed based on the findings.

CONCLUSION

Preregistrant pharmacists perceive experience within the workforce and communication and collaboration as the most desired by employers for entry-level pharmacy positions. Education and research competencies were seen as least useful to the job. There was a disconnect between skills gained in university and translation to practice. Academics could enhance the better preregistrant pharmacists' reflection of the skills and competencies they have developed employability by (1) providing portfolio management from the beginning of the course that collects evidence and maps to competencies; (2) integrating learning opportunities across all competencies; and (3) regular skills coaching/mentoring from practicing pharmacists to ensure students are aware of current needs in the job market.

Coaching and talent development in esports: a theoretical framework and suggestions for future research

Esports is a growing phenomenon that is capturing the attention of individuals worldwide, and has grown to provide professional and lucrative careers for those who reach the upper echelons. One question that arises, is how esports athletes develop the necessary skills required to improve and compete. This perspective piece opens the door to skill acquisition within esports and how research through an ecological approach can benefit researchers and practitioners as they understand the various perception-action couplings and decision-making challenges faced by esports athletes. We will identify and discuss what constraints look like in esports, the role of affordances, and theorize the implementation of a constraints-led approach in contrasting esports genres. As esports is technology-heavy in nature and generally sedentary, the use of eye-tracking technology is argued to represent an effective method to better understand perceptual attunement between individuals and teams. Future research into skill acquisition in esports is needed to develop a clearer picture of what makes the greatest esports player so great, and how newer players can be developed effectively.

Incidental learning in music reading: The music contingency learning task

The present report investigated whether nonmusicians can incidentally learn musical skills needed for sight-reading. On each trial, participants identified a note name written inside of a note on the musical staff. In Experiment 1, each note was presented frequently with the congruent note name (e.g., "do" with the note for "do") and rarely with the incongruent names (e.g., "do" with the note for "fa"). With or without deliberate learning instructions, a robust contingency learning effect was observed: faster responses for congruent trials compared with incongruent trials. Participants also explicitly identified the meaning of the note positions more accurately than chance. Experiment 2 ruled out the potential influence of preexisting knowledge on the contingency learning effect by presenting notes most often with an incongruent note name. Robust learning was again observed, suggesting that participants acquired sufficient knowledge of musical notation to produce automatic influences on behaviour (e.g., akin to the interference effect previously found in skilled musicians). A congruency effect was additionally observed in Experiment 2, however. Experiment 3 further explored to what extent this congruency effect might be due to prior music knowledge and/or spatial stimulus-response compatibility between note and response locations (analogous to the SMARC effect). Overall, our results open up new avenues for investigating the incidental learning of complex material, musical or otherwise, and for reinforcing learning even further.

Advanced neonatal procedural skills: a simulation-based workshop: impact and skill decay

BACKGROUND

Trainees aiming to specialize in Neonatal Perinatal Medicine (NPM), must be competent in a wide range of procedural skills as per the Royal College of Canada. While common neonatal procedures are frequent in daily clinical practice with opportunity to acquire competence, there are substantial gaps in the acquisition of advanced neonatal procedural skills. With the advent of competency by design into NPM training, simulation offers a unique opportunity to acquire, practice and teach potentially life-saving procedural skills. Little is known on the effect of simulation training on different areas of competence, and on skill decay.

METHODS

We designed a unique simulation-based 4-h workshop covering 6 advanced procedures chosen because of their rarity yet life-saving effect: chest tube insertion, defibrillation, exchange transfusion, intra-osseus (IO) access, ultrasound-guided paracentesis and pericardiocentesis. Direct observation of procedural skills (DOPS), self-perceived competence, comfort level and cognitive knowledge were measured before (1), directly after (2), for the same participants after 9-12 months (skill decay, 3), and directly after a second workshop (4) in a group of NPM and senior general pediatric volunteers.

RESULTS

The DOPS for all six procedures combined for 23 participants increased from 3.83 to 4.59. Steepest DOPS increase pre versus post first workshop were seen for Defibrillation and chest tube insertion. Skill decay was evident for all procedures with largest decrease for Exchange Transfusion, followed by Pericardiocentesis, Defibrillation and Chest Tube. Self-perceived competence, comfort and cognitive knowledge increased for all six procedures over the four time points. Exchange Transfusion stood out without DOPS increase, largest skill decay and minimal impact on self-assessed competence and comfort. All skills were judged as better by the preceptor, compared to self-assessments.

CONCLUSIONS

The simulation-based intervention advanced procedural skills day increased preceptor-assessed directly observed procedural skills for all skills examined, except exchange transfusion. Skill decay affected these skills after 9-12 months. Chest tube insertions and Defibrillations may benefit from reminder sessions, Pericardiocentesis may suffice by teaching once. Trainees' observed skills were better than their own assessment. The effect of a booster session was less than the first intervention, but the final scores were higher than pre-intervention.

TRIAL REGISTRATION

Not applicable, not a health care intervention.

Improving old tricks as new: Young adults learn from repeating everyday activities

The notion that young healthy adults can substantially improve in activities that are part of their daily routine is often overlooked because it is assumed that such activities have come to be fully mastered. We followed, in young healthy adults, the effects of repeated executions of the Timed-Up-and-Go (TUG) task, a clinical test that assesses the ability to execute motor activities relevant to daily function-rising from a seated position, walking, turning and returning to a seated position. The participants (N = 15) performed 18 consecutive trials of the TUG in one session, and were retested on the following day and a week later. The participants were video recorded and wore inertial measurement units. Task execution times improved robustly; performance was well fitted by a power function, with large gains at the beginning of the session and nearing plateau in later trials, as one would expect in the learning of a novel task. Moreover, these gains were well retained overnight and a week later, with further gains accruing in the subsequent test-sessions. Significant intra-session and inter-session changes occurred in step kinematics as well; some aspects underwent inter-sessions recalibrations, but other aspects showed delayed inter-session changes, suggesting post-practice memory consolidation processes. Even common everyday tasks can be improved upon by practice; a small number of consecutive task repetitions can trigger lasting gains in young healthy individuals performing highly practiced routine tasks. This new learning in highly familiar tasks proceeded in a time-course characteristic of the acquisition of novel 'how to' (procedural) knowledge.

Gritting One's way to success - Grit explains skill in elite youth soccer players beyond (deliberate) practice

Practice is one of the most important predictors of skill. To become an expert, performers must engage in practice for a prolonged time to develop the psychological characteristics necessary for outstanding performance. Deliberate practice (DP), that is focused repetitive activities with corrective feedback, is particularly beneficial for skill development. The amount of accumulated DP differentiates experts and novices. However, the predictive strength of DP weakens considerably when it comes to differentiating between differently skilled experts, leaving a way clear for other non-practice related factors to exercise their influence. In this paper, we demonstrate using a large sample (388) of elite youth soccer players that one such factor, the personality trait of grit, predicts expertise level both directly and indirectly. Grittier players accumulated more time in coach-led team practice, the activity, which is arguably closest to DP in team sports, which in turn predicted the skill level. Other practice activities, such as self-led training or playing with peers, were not predictive of skill level, neither were they influenced by grit. Grit, however, continued to exert a direct positive influence on the skill level of players even after accounting for the hours of DP accumulated. Overall, a standard deviation of change in the grit score resulted in at least a third of standard deviation improvement in skill. Our findings highlight the need for the inclusion of additional factors in theoretical frameworks in situations where the predictive power of traditional expertise factors, such as practice, is limited.

Motor Memory Consolidation Deficits in Parkinson's Disease: A Systematic Review with Meta-Analysis

BACKGROUND

The ability to encode and consolidate motor memories is essential for persons with Parkinson's disease (PD), who usually experience a progressive loss of motor function. Deficits in memory encoding, usually expressed as poorer rates of skill improvement during motor practice, have been reported in these patients. Whether motor memory consolidation (i.e., motor skill retention) is also impaired is unknown.

OBJECTIVE

To determine whether motor memory consolidation is impaired in PD compared to neurologically intact individuals.

METHODS

We conducted a pre-registered systematic review (PROSPERO: CRD42020222433) following PRISMA guidelines that included 46 studies.

RESULTS

Meta-analyses revealed that persons with PD have deficits in retaining motor skills (SMD = -0.17; 95% CI = -0.32, -0.02; p = 0.0225). However, these deficits are task-specific, affecting sensory motor (SMD = -0.31; 95% CI -0.47, -0.15; p = 0.0002) and visuomotor adaptation (SMD = -1.55; 95% CI = -2.32, -0.79; p = 0.0001) tasks, but not sequential fine motor (SMD = 0.17; 95% CI = -0.05, 0.39; p = 0.1292) and gross motor tasks (SMD = 0.04; 95% CI = -0.25, 0.33; p = 0.7771). Importantly, deficits became non-significant when augmented feedback during practice was provided, and additional motor practice sessions reduced deficits in sensory motor tasks. Meta-regression analyses confirmed that deficits were independent of performance during encoding, as well as disease duration and severity.

CONCLUSION

Our results align with the neurodegenerative models of PD progression and motor learning frameworks and emphasize the importance of developing targeted interventions to enhance motor memory consolidation in PD.

Parallel, component training in robotic total mesorectal excision

There has been widespread adoption of robotic total mesorectal excision (TME) for rectal cancer in recent years. There is now increasing interest in training robotic novice surgeons in robotic TME surgery using the principles of component-based learning. The aims of our study were to assess the feasibility of delivering a structured, parallel, component-based, training curriculum to surgical trainees and fellows. A prospective pilot study was undertaken between January 2021 and May 2021. A dedicated robotic training pathway was designed with two trainees trained in parallel per each robotic case based on prior experience, training grade and skill set. Component parts of each operation were allocated by the robotic trainer prior to the start of each case. Robotic proficiency was assessed using the Global Evaluative Assessment of Robotic Skills (GEARS) and the EARCS Global Assessment Score (GAS). Three trainees participated in this pilot study, performing a combined number of 52 TME resections. Key components of all 52 TME operations were performed by the trainees. GEARS scores improved throughout the study, with a mean overall baseline score of 17.3 (95% CI 15.1-1.4) compared to an overall final assessment mean score of 23.8 (95% CI 21.6-25.9), p = 0.003. The GAS component improved incrementally for all trainees at each candidate assessment (p < 0.001). Employing a parallel, component-based approach to training in robotic TME surgery is safe and feasible and can be used to train multiple trainees of differing grades simultaneously, whilst maintaining high-quality clinical outcomes.

Domesticating the condition: Design lessons gained from a marathon on how to cope with barriers imposed by type 1 diabetes

Through analytical autoethnographic analysis of marathon preparation, this study examines challenges faced by people with Type 1 Diabetes (T1D) who engage in high-performance sports. Autoethnographer and second-person perspectives (T1D runners, family members, and health providers) were collected through introspective activities (autoethnographic diary and in-depth interviews) to understand the T1D runner's coping experience. Six insights involved in T1D self-management were identified and analyzed with reference to related design tools (prototyping, archetyping and journey mapping). Finally, we conclude with a discussion of how endurance physical activity (PA) such as running helps to "domesticate" T1D, a term coined to reflect the difficulties that T1D presents for PA accomplishment and how T1D runners' experiences give them an opportunity to overcome PA barriers promoting physical culture and enriching further health psychology studies.

What are clinically relevant performance metrics in robotic surgery? A systematic review of the literature

A crucial element of any surgical training program is the ability to provide procedure-specific, objective, and reliable measures of performance. During robotic surgery, objective clinically relevant performance metrics (CRPMs) can provide tailored contextual feedback and correlate with clinical outcomes. This review aims to define CRPMs, assess their validity in robotic surgical training and compare CRPMs to existing measures of robotic performance. A systematic search of Medline and Embase databases was conducted in May 2022 following the PRISMA guidelines. The search terms included Clinically Relevant Performance Metrics (CRPMs) OR Clinically Relevant Outcome Measures (CROMs) AND robotic surgery. The study settings, speciality, operative context, study design, metric details, and validation status were extracted and analysed. The initial search yielded 116 citations, of which 6 were included. Citation searching identified 3 additional studies, resulting in 9 studies included in this review. Metrics were defined as CRPMs, CROMs, proficiency-based performance metrics and reference-procedure metrics which were developed using a modified Delphi methodology. All metrics underwent both contents and construct validation. Two studies found a strong correlation with GEARS but none correlated their metrics with patient outcome data. CRPMs are a validated and objective approach for assessing trainee proficiency. Evaluating CRPMs with other robotic-assessment tools will facilitate a multimodal metric evaluation approach to robotic surgery training. Further studies should assess the correlation with clinical outcomes. This review highlights there is significant scope for the development and validation of CRPMs to establish proficiency-based progression curricula that can be translated from a simulation setting into clinical practice.

An app-enhanced cognitive fitness training program for athletes: The rationale and validation protocol

The core dimensions of cognitive fitness, such as attention and cognitive control, are emerging through a transdisciplinary expert consensus on what has been termed the Cognitive Fitness Framework (CF2). These dimensions represent key drivers of cognitive performance under pressure across many occupations, from first responders to sport, performing arts and the military. The constructs forming the building blocks of CF2 come from the RDoC framework, an initiative of the US National Institute of Mental Health (NIMH) aimed at identifying the cognitive processes underlying normal and abnormal behavior. Similar to physical conditioning, cognitive fitness can be improved with deliberate practice. This paper reports the development of a prototype cognitive fitness training program for competitive athletes and the protocol for its evaluation. The program is focused on primary cognitive capacities and subtending skills for adjusting training rhythms and enhancing readiness for competition. The project is driven by the Australian Psychological Society's College of Sport & Exercise Psychology and includes the development of a Cognitive Gym program for a smartphone app-enhanced implementation. Its key building blocks are training protocols (drills) connected by a periodized training plan. A website with background supporting resources has also been developed as part of the project. National-level training squads will participate in a three-week pilot evaluation protocol, assessing the program's efficacy and usability through gamified cognitive assessment of participants' training gains and coaching staff evaluations, respectively. Both near and far transfer of training effects will be examined.

Typing expertise in a large student population

Typing has become a pervasive mode of language production worldwide, with keyboards fully integrated in a large part of many daily activities. The bulk of the literature on typing expertise concerns highly trained professional touch-typists, but contemporary typing skills mostly result from unconstrained sustained practice. We measured the typing performance of a large cohort of 1301 university students through an online platform and followed a preregistered plan to analyse performance distributions, practice factors, and cognitive variables. The results suggest that the standard model with a sharp distinction between novice and expert typists may be inaccurate to account for the performance of the current generation of young typists. More generally, this study shows how the mere frequent use of a new tool can lead to the incidental development of high expertise.

Factors affecting expert performance in bid evaluation: An integrated approach

Experts play a crucial role in underpinning decision-making in most management situations. While recent studies have disclosed the impacts of individuals’ inherent cognition and the external environment on expert performance, these two-dimensional mechanisms remain poorly understood. In this study, we identified 14 factors that influence expert performance in a bid evaluation and applied cross-impact matrix multiplication to examine the interdependence of the factors. The results indicate that the two dimension-related factors affect each other within a person–environment system, and a poor situation perception gives rise to the deviation of expert performance. Expert performance can be improved if external supervision and expertise are strengthened through deliberate practices. The study proposes a new expert performance research tool, elucidates its mechanism in bid evaluation from a cognitive psychology perspective, and provides guidelines for its improvement in workplace contexts.

Neurosurgery resident training using blended learning concepts: course development and participant evaluation

OBJECTIVE

Restrictions on working time and healthcare expenditures, as well as increasing subspecialization with caseload requirements per surgeon and increased quality-of-care expectations, provide limited opportunities for surgical residents to be trained in the operating room. Yet, surgical training requires goal-oriented and focused practice. As a result, training simulators are increasingly utilized. The authors designed a two-step blended course consisting of a personalized adaptive electronic learning (e-learning) module followed by simulator training. This paper reports on course development and the evaluation by the first participants.

METHODS

Adaptive e-learning was curated by learning engineers based on theoretical information provided by clinicians (subject matter experts). A lumbar spine model for image-guided spinal injections was used for the simulator training. Residents were assigned to the e-learning module first; after its completion, they participated in the simulator training. Performance data were recorded for each participant’s e-learning module, which was necessary to personalize the learning experience to each individual’s knowledge and needs. Simulator training was organized in small groups with a 1-to-4 instructor-to-participant ratio. Structured assessments were undertaken, adapted from the Student Evaluation of Educational Quality.

RESULTS

The adaptive e-learning module was curated, reviewed, and approved within 10 weeks. Eight participants have taken the course to date. The overall rating of the course is very good (4.8/5). Adaptive e-learning is well received compared with other e-learning types (8/10), but scores lower regarding usefulness, efficiency, and fun compared with the simulator training, despite improved conscious competency (32.6% ± 15.1%) and decreased subconscious incompetency (22.8% ± 10.2%). The subjective skill level improved by 20%. Asked about the estimated impact of the course, participants indicated that they had either learned something new that they plan to use in their practice (71.4%) or felt reassured in their practice (28.6%).

CONCLUSIONS

The development of a blended training course combining adaptive e-learning and simulator training in a rapid manner is feasible and leads to improved skills. Simulator training is rated more valuable by surgical trainees than theoretical e-learning; the impact of this type of training on patient care needs to be further investigated.

Perspectives of Hybrid Performing Arts Education in the Post-Pandemic Era: An Empirical Study in Hong Kong

While the COVID-19 pandemic has been raging across the continents, performing arts educators have unlearned and adjusted their pedagogies in course delivery to surmount the challenges caused by the COVID-19 pandemic. Subject to the COVID-19 pandemic situation easing in Hong Kong and around the world, the whole education sector seems to be bouncing back to normal gradually. Meanwhile, there are effective lessons and insights to be learned from the hybrid pedagogy during the pandemic, which could further benefit the new normal period (post-pandemic) of performing arts education. To examine the current practice of digital learning among students and faculty (attitudes towards hybrid, online, and face-to-face learning and preferences about learning mode for professional development/training workshops), this empirical study looks at 408 students and 17 faculty members at a leading performing arts institute in Hong Kong. This study locates the key issues for performing arts educators regarding online/hybrid teaching and learning. It presents lessons and insights for quality insurance and improvement. Findings can inform the future development of digital teaching and learning for the performing arts as well as for other practice-based subjects.

When (deliberate) practice is not enough – the role of intelligence, practice, and knowledge in academic performance

It is well established that academic performance (AP) depends on a number of factors, such as intellectual capacities, practice, and previous knowledge. We know little about how these factors interact as they are rarely measured simultaneously. Here we present mediated-Factors of Academic Performance (m-FAP) model, which simultaneously assesses direct and indirect, mediated, effects on AP. In a semester-long study with 118 first-year college students, we show that intelligence and working memory only indirectly influenced AP on a familiar, less challenging college course (Introduction to Psychology). Their influence was mediated through previous knowledge and self-regulated learning activities akin to deliberate practice. In a novel and more challenging course (Statistics in Psychology), intellectual capacities influenced performance both directly and indirectly through previous knowledge. The influence of deliberate practice, however, was considerably weaker in the novel course. The amount of time and effort that the students spent on the more difficult course could not offset the advantage of their more intelligent and more knowledgeable peers. The m–FAP model explains previous contradictory results by providing a framework for understanding the extent and limitations of individual factors in AP, which depend not only on each other, but also on the learning context.

A resident robotic curriculum utilizing self-selection and a web-based feedback tool

To describe an obstetrics and gynecology residency robotic curriculum, facilitated by a web-based feedback and case-tracking tool, allowing for self-selection into advanced training. Phase I (Basic) was required for all residents and included online training modules, online assessment, and robotic bedside assistant dry lab. Phase II (Advanced) was elective console training. Before live surgery, 10 simulation drills completed to proficiency were required. A web-based tool was used for surgical feedback and case-tracking. Online assessments, drill reports, objective GEARS assessments, subjective feedback, and case-logs were reviewed (7/2018-6/2019). A satisfaction survey was reviewed. Twenty four residents completed Phase I training and 10 completed Phase II. To reach simulation proficiency, residents spent a median of 4.1 h performing required simulation drills (median of 10 (3, 26) attempts per drill) before live surgery. 128 post-surgical feedback entries were completed after performance as bedside assistant (75%, n = 96) and console surgeon (5.5%, n = 7). The most common procedure was hysterectomy 111/193 (58%). Resident console surgeons performed portions of 32 cases with a mean console time of 34.6 ± 19.5 min. Mean GEARS score 20.6 ± 3.7 (n = 28). Mean non-technical feedback results: communication (4.2 ± 0.8, n = 61), workload management (3.9 ± 0.9, n = 54), team skills (4.3 ± 0.8, n = 60). Residents completing > 50% of case assessed as "apprentice" 38.5% or "competent" 23% (n = 13). After curriculum change, 100% of surveyed attendings considered residents prepared for live surgical training, vs 17% (n = 6) prior to curriculum change [survey response rate 27/44 (61%)]. Attendings and residents were satisfied with curriculum; 95% and recommended continued use 90% (n = 19).This two-phase robotic curriculum allows residents to self-select into advanced training, alleviating many challenges of graduated robotic training.

Effect of Attentional Focus on Sprint Performance: A Meta-Analysis

Sprinting is often seen in a variety of sports. Focusing one's attention externally before sprinting has been demonstrated to boost sprint performance. The present study aimed to systematically review previous findings on the impact of external focus (EF), in comparison to internal focus (IF), on sprint performance. A literature search was conducted in five electronic databases (APA PsycINFO, PubMed, Scopus, SPORTDiscus, and Web of Science). A random-effects model was used to pool Hedge's g with 95% confidence intervals (CIs). The meta-analysis included six studies with a total of 10 effect sizes and 166 participants. In general, the EF condition outperformed the IF condition in sprint performance (g = 0.279, 95% CI [0.088, 0.470], p = 0.004). The subgroup analysis, which should be viewed with caution, suggested that the benefits associated with the EF strategy were significant in low-skill sprinters (g = 0.337, 95% CI [0.032, 0.642], p = 0.030) but not significant in high-skill sprinters (g = 0.246, 95% CI [-0.042, 0.533], p = 0.094), although no significant difference was seen between these subgroups (p = 0.670). The reported gain in sprint performance due to attentional focus has practical implications for coaches and athletes, as making tiny adjustments in verbal instructions can lead to significant behavioral effects of great importance in competitive sports.

Quality-assured training in the evaluation of cochlear implant electrode position: a prospective experimental study

BACKGROUND

The objective of this study was to demonstrate the utility of an approach in training predoctoral medical students, to enable them to measure electrode-to-modiolus distances (EMDs) and insertion-depth angles (aDOIs) in cochlear implant (CI) imaging at the performance level of a single senior rater.

METHODS

This prospective experimental study was conducted on a clinical training dataset comprising patients undergoing cochlear implantation with a Nucleus® CI532 Slim Modiolar electrode (N = 20) or a CI512 Contour Advance electrode (N = 10). To assess the learning curves of a single medical student in measuring EMD and aDOI, interrater differences (senior-student) were compared with the intrarater differences of a single senior rater (test-retest). The interrater and intrarater range were both calculated as the distance between the 0.1th and 99.9th percentiles. A "deliberate practice" training approach was used to teach knowledge and skills, while correctives were applied to minimize faulty data-gathering and data synthesis.

RESULTS

Intrarater differences of the senior rater ranged from - 0.5 to 0.5 mm for EMD and - 14° to 16° for aDOI (respective medians: 0 mm and 0°). Use of the training approach led to interrater differences that matched this after the 4th (EMD) and 3rd (aDOI) feedback/measurement series had been provided to the student.

CONCLUSIONS

The training approach enabled the student to evaluate the CI electrode position at the performance level of a senior rater. This finding may offer a basis for ongoing clinical quality assurance for the assessment of CI electrode position.

What medical students think about measurement of their well-being: cross-sectional survey and qualitative interviews

OBJECTIVES

To find out how medical students think well-being should be measured.

DESIGN

A mixed-methods study comprising a cross-sectional online survey (November 2020-March 2021) and semi-structured online interviews. Views on the frequency of availability for measurement, the format, type and purpose of measurement, and with whom well-being should be discussed were measured. When an outcome was scored 7-9 on a 9-point Likert scale of agreement by ≥75% of participants it was considered critical. Inductive thematic analysis was undertaken on the interview transcripts.

SETTING

All medicine programmes at University of Southampton.

PARTICIPANTS

Medical students from all years took part in the survey (n=118) and interviews (n=16).

RESULTS

Most participants (94%) felt able to give 5 min to measure their well-being at least once per month. Research, governance and individual feedback were all considered critically important. Only subjective assessments undertaken by the individual in real-time were rated critically important (78.1%) measurement tools. Students selected that they would discuss their well-being with other medical students (n=87) nearly as often as they selected a member of the faculty (n=104). Five interview themes further explained these findings: (1) well-being is mental well-being; (2) exercise and support from friends and family are most important; (3) isolation and the design of the medicine programme are detrimental to well-being; (4) there are advantages to surveys, and conversations; (5) personal academic tutors and medical students in later years are the best to discuss well-being with.

CONCLUSIONS

Medical students thought that measurement of their well-being was critically important for governance showing their support for quality assurance of well-being and peer support. They wanted to be able to choose surveys, or conversations, to measure their well-being, as well as the person they discussed well-being with. Four recommendations are discussed in light of these findings.

Using machine learning to identify quality-of-care predictors for emergency caesarean sections: a retrospective cohort study

OBJECTIVES

Emergency caesarean sections (ECS) are time-sensitive procedures. Multiple factors may affect team efficiency but their relative importance remains unknown. This study aimed to identify the most important predictors contributing to quality of care during ECS in terms of the arrival-to-delivery interval.

DESIGN

A retrospective cohort study. ECS were classified by urgency using emergency categories one/two and three (delivery within 30 and 60 min). In total, 92 predictor variables were included in the analysis and grouped as follows: 'Maternal objective', 'Maternal psychological', 'Fetal factors', 'ECS Indication', 'Emergency category', 'Type of anaesthesia', 'Team member qualifications and experience' and 'Procedural'. Data was analysed with a linear regression model using elastic net regularisation and jackknife technique to improve generalisability. The relative influence of the predictors, percentage significant predictor weight (PSPW) was calculated for each predictor to visualise the main determinants of arrival-to-delivery interval.

SETTING AND PARTICIPANTS

Patient records for mothers undergoing ECS between 2010 and 2017, Nordsjællands Hospital, Capital Region of Denmark.

PRIMARY OUTCOME MEASURES

Arrival-to-delivery interval during ECS.

RESULTS

Data was obtained from 2409 patient records for women undergoing ECS. The group of predictors representing 'Team member qualifications and experience' was the most important predictor of arrival-to-delivery interval in all ECS emergency categories (PSPW 25.9% for ECS category one/two; PSPW 35.5% for ECS category three). In ECS category one/two the 'Indication for ECS' was the second most important predictor group (PSPW 24.9%). In ECS category three, the second most important predictor group was 'Maternal objective predictors' (PSPW 24.2%).

CONCLUSION

This study provides empirical evidence for the importance of team member qualifications and experience relative to other predictors of arrival-to-delivery during ECS. Machine learning provides a promising method for expanding our current knowledge about the relative importance of different factors in predicting outcomes of complex obstetric events.

Competition age: does it matter for swimmers?

OBJECTIVE

To establish reference data on required competition age regarding performance levels for both sexes, all swimming strokes, and race distances and to determine the effect of competition age on swimming performance in the context of other common age metrics. In total, 36,687,573 race times of 588,938 swimmers (age 14.2 ± 6.3 years) were analyzed. FINA (Fédération Internationale de Natation) points were calculated to compare race times between swimming strokes and race distances. The sum of all years of race participation determined competition age.

RESULTS

Across all events, swimmers reach top-elite level, i.e. > 900 FINA points, after approximately 8 years of competition participation. Multiple-linear regression analysis explained up to 40% of variance in the performance level and competition age showed a stable effect on all race distances for both sexes (β = 0.19 to 0.33). Increased race distance from 50 to 1500 m, decreased effects of chronological age (β = 0.48 to - 0.13) and increased relative age effects (β = 0.02 to 0.11). Reference data from the present study should be used to establish guidelines and set realistic goals for years of competition participation required to reach certain performance levels. Future studies need to analyze effects of transitions between various swimming strokes and race distances on peak performance.

Diabetes Capabilities for the Healthcare Workforce Identified via a 3-Staged Modified Delphi Technique

Consumers access health professionals with varying levels of diabetes-specific knowledge and training, often resulting in conflicting advice. Conflicting health messages lead to consumer disengagement. The study aimed to identify capabilities required by health professionals to deliver diabetes education and care to develop a national consensus capability-based framework to guide their training. A 3-staged modified Delphi technique was used to gain agreement from a purposefully recruited panel of Australian diabetes experts from various disciplines and work settings. The Delphi technique consisted of (Stage I) a semi-structured consultation group and pre-Delphi pilot, (Stage II) a 2-phased online Delphi survey, and (Stage III) a semi-structured focus group and appraisal by health professional regulatory and training organisations. Descriptive statistics and central tendency measures calculated determined quantitative data characteristics and consensus. Content analysis using emergent coding was used for qualitative content. Eighty-four diabetes experts were recruited from nursing and midwifery (n = 60 [71%]), allied health (n = 17 [20%]), and pharmacy (n = 7 [9%]) disciplines. Participant responses identified 7 health professional practice levels requiring differences in diabetes training, 9 capability areas to support care, and 2 to 16 statements attained consensus for each capability-259 in total. Additionally, workforce solutions were identified to expand capacity for diabetes care. The rigorous consultation process led to the design and validation of a Capability Framework for Diabetes Care that addresses workforce enablers identified by the Australian National Diabetes Strategy. It recognises diversity, creating shared understandings of diabetes across health professional disciplines. The findings will inform diabetes policy, practice, education, and research.

Deliberate Practice and Motor Learning Principles to Underpin the Design of Training Interventions for Improving Lifting Movement in the Occupational Sector: A Perspective and a Pilot Study on the Role of Augmented Feedback

Spine posture during repetitive lifting is one of the main risk factors for low-back injuries in the occupational sector. It is thus critical to design appropriate intervention strategies for training workers to improve their posture, reducing load on the spine during lifting. The main approach to train safe lifting to workers has been educational; however, systematic reviews and meta-analyses have shown that this approach does not improve lifting movement nor reduces the risk of low back injury. One of the main limitations of this approach lies in the amount, quality and context of practice of the lifting movement. In this article, first we argue for integrating psychologically-grounded perspectives of practice design in the development of training interventions for safe lifting. Principles from deliberate practice and motor learning are combined and integrated. Given the complexity of lifting, a training intervention should occur in the workplace and invite workers to repeatedly practice/perform the lifting movement with the clear goal of improving their lifting-related body posture. Augmented feedback has a central role in creating the suitable condition for achieving such intervention. Second, we focus on spine bending as risk factor and present a pilot study examining the benefits and boundary conditions of different feedback modalities for reducing bending during lifting. The results showed how feedback modalities meet differently key requirements of deliberate practice conditions, i.e., feedback has to be informative, individualized and actionable. Following the proposed approach, psychology will gain an active role in the development of training interventions, contributing to finding solutions for a reduction of risk factors for workers.
