RÉSUMÉ

Students' new knowledge is gradually built up in the context of the task for which it is required and consolidated by applying it to clinical cases. As students see more and more clinical cases the knowledge emerges from an associative mesh of different levels of understanding. During tutorial clinical teaching, residents should be gradually exposed to an increasing range of real-world learning tasks and increasing levels of complexity. This exposure allows them to gradually develop shortcuts in the retrieval of their knowledge. This commentary provides a rationale for the construction of knowledge and the pivotal role that clinical tutorial teaching plays in this task.

RÉSUMÉ

The Performance Index (P-Index) is a measure for evaluating mobility-related dual-task performance in older adults. The identification of specific clinicodemographic factors predictive of P-Index scores, however, remains unclear. This cross-sectional study analyzed data from 120 community-dwelling older adults (average age 71.3 ± 11.23 years) to explore clinicodemographic variables that influence P-Index scores during the instrumented timed up and go test. Unadjusted analyses suggested several factors, including age, gender, body mass index, Mini-Mental Status Examination scores, functional reach test performance, history of falls, ethnicity, Geriatric Depression Scale scores, alcohol consumption, and educational levels, as potential predictors of P-Index. However, adjusted multinomial multiple regression analysis revealed Geriatric Depression Scale and Mini-Mental Status Examination scores as the exclusive independent predictors of P-Index classifications, segmented into high, intermediate, or low (percentiles ≤ 25, 26-74, or ≥ 75, respectively). A significant association was observed between the manifestation of depressive symptoms, lower Mini-Mental Status Examination scores, and reduced cognitive-motor performance. The findings implicate depressive symptoms and low cognitive performance as substantial impediments to optimal dual-task mobility within this cohort. Further studies are warranted to examine the efficacy of cognitive stimulation and antidepressant therapy, in augmenting mobility-related dual-task performance among older adults.

RÉSUMÉ

Background: Burnout syndrome, characterized by physical, mental, and emotional exhaustion due to continuous exposure to high-stress work conditions, has been increasingly recognized as a serious occupational phenomenon, especially amongst healthcare professionals. Recent studies indicate that illegitimate tasks-activities unrelated to one's role are a significant factor contributing to burnout. However, given the variability of work environments across regions, these findings may not apply universally. Objective: To investigate the behavior of the relationship between burnout and illegitimate tasks among healthcare professionals in Guayaquil, Ecuador. Methods: We conducted a survey of 562 healthcare professionals, including physicians, nurses, and medical/nursing interns, employing the Copenhagen Burnout Inventory and Bern Illegitimate Task Scale. Regression models were developed to predict burnout levels based on multiple factors, including demographic characteristics, professional roles, and perceptions of illegitimate tasks. Results: We revealed a statistically significant positive correlation between burnout and illegitimate tasks, with correlation coefficients ranging from 0.320 to 0.588, with higher levels of illegitimate tasks leading to increased burnout. Interestingly, we also found that age and length of service were negatively correlated with burnout, suggesting that these factors may serve as protective elements against burnout. Conclusions: Illegitimate tasks had an impact on burnout amongst healthcare professionals and emphasized the need for organizational strategies aimed at better task management to mitigate burnout risk.

RÉSUMÉ

The literature reports contradictory results regarding the influence of visual cues on speech perception tasks in children with phonological disorder (PD). This study aimed to compare the performance of children with (n = 15) and without PD (n = 15) in audiovisual perception task in voiceless fricatives. Assuming that PD could be associated with an inability to integrate phonological information from two sensory sources, we presumed that children with PD would present difficulties in integrating auditory and visual cues compared to typical children. A syllable identification task was conducted. The stimuli were presented according to four conditions: auditory-only (AO); visual-only (VO); audiovisual congruent (AV+); and audiovisual incongruent (AV-). The percentages of correct answers and the respective reaction times in the AO, VO, and AV+ conditions were considered for the analysis. The correct percentage of auditory stimuli was considered for the AV- condition, as well as the percentage of perceptual preference: auditory, visual, and/or illusion (McGurk effect), with the respective reaction time. In comparing the four conditions, children with PD presented a lower number of correct answers and longer reaction time than children with typical development, mainly for the VO. Both groups showed a preference for auditory stimuli for the AV- condition. However, children with PD showed higher percentages for visual perceptual preference and the McGurk effect than typical children. The superiority of typical children over PD children in auditory-visual speech perception depends on type of stimuli and condition of presentation.

RÉSUMÉ

Successive Negative Contrast (SNC) occurs when there is a reduction in the quantity or quality of a reward that is expected according to the presence of contextual cues. This induces an emotional response of frustration that is similar to stress. While this phenomenon has been observed in several mammal species, findings in domestic dogs have been inconsistent, although this issue has strong relevance in dog training. The aim of this study was to assess the effects of Successive Negative Contrast in two responses that had already been studied in this species, but with an increase in the methodological rigor and variations in the experimental conditions to examine the generalizability of the phenomenon. To this end, experimental dogs experienced a pre-shift phase in which they received a high-value reward (liver), followed by a post-shift phase in which they obtained a low-value reward (dry dog food), and then a re-shift phase in which the high-value reward was available again. Control dogs received dry food in all phases. The results show a contrast effect on the behavior of following human pointing to obtain food (Study 1). On the contrary, there were no differences in problem solving behavior after the de- and re-evaluation of the reward during a non-social task (Study 2). The results support that Successive Negative Contrast is not a consistent phenomenon in pet dogs. It is possible that certain characteristics of dogs such as the great availability of high-value rewards in their daily lives could attenuate the effects of a reduction in incentive value.

RÉSUMÉ

This study aimed to compare procedural learning skills between Spanish-speaking preschool children (ages 4 years to 4 years, 11 months) with developmental language disorder (DLD) and their chronologically matched typically developing (TD) peers. Using the serial reaction time (SRT) task, participants (30 children with DLD and 30 TD children) responded to visual stimuli in a sequenced manner over four blocks, followed by a random order block. The task assessed reaction time (RT) and accuracy. The results showed a significant interaction between group and block for RT and accuracy, with children with DLD exhibiting longer RTs and accuracy deficits across blocks. In contrast, the TD group showed higher RT efficiency and accuracy in the sequential blocks and, as expected, decreased performance in the random block according to the experimental manipulation. Overall, the results of this investigation suggest that there was no implicit learning in the DLD group, as indicated by the SRT task paradigms of procedural memory. These findings align with some aspects of the procedural deficit hypothesis (PDH), which suggests that linguistic deficits in the DLD population may derive from a deficit in sequential learning from the procedural memory system domain in the Spanish context.

RÉSUMÉ

Mate Marote is an open-access cognitive training software aimed at children between 4 and 8 years old. It consists of a set of computerized games specifically tailored to train and evaluate Executive Functions (EF), a class of processes critical for purposeful, goal-directed behavior, including working memory, planning, flexibility, and inhibitory control. Since 2008, several studies were performed with this software at children's own schools in interventions supervised in-person by cognitive scientists. After 2015, we incorporated naturalistic, yet controlled, interventions with children's own teachers' help. The platform includes a battery of standardized tests, disguised as games, to assess children's EF. The main question that emerges is whether the results, obtained with these traditional tasks but conducted without the presence of researchers, are comparable to those widely reported in the literature, that were obtained in more supervised settings. In this study, we were able to replicate the expected difficulty and age effects in at least one of the analyzed dependent variables of each employed test. We also report important discrepancies between the expected and the observed response time patterns, specifically for time-constrained tasks. We hereby discuss the benefits and setbacks of a new possible strategy for this type of assessment in naturalistic settings. We conclude that this battery of established EF tasks adapted for its remote usage is appropriate to measure the expected mental processes in naturalistic settings, enriching opportunities to upscale cognitive training interventions at schools. These types of tools can constitute a concerted strategy to bring together educational neuroscience research and real-life practice.

RÉSUMÉ

This descriptive study aimed to investigate the current practices of Portuguese and Brazilian soccer coaches in the design and implementation of small-sided games (SSGs) in soccer. A total of 187 male coaches participated in the online survey, consisting of 82 Portuguese and 105 Brazilian individuals. These coaches held various positions within the technical staff, with 63 serving as head coaches, 38 as assistant coaches, 38 as physical trainers, and 48 in other roles related to the technical staff. Additionally, the participants represented both youth (n = 102) and adult competitive levels (n = 59), along with some who were not currently associated with a specific group. The survey consisted of 32 questions divided into three main sections: (i) the timing of SSG application, (ii) the methods used for applying SSGs, and (iii) the reasons for applying SSGs. The Chi-square test revealed a statistically significant association between nationality and the frequency of SSGs used in training sessions during the pre-season (p = 0.039) and in-season (p < 0.001). Moreover, significant association between nationality and the time allocated to employing SSGs for targeting aerobic training (p < 0.001) was found. There was a significant association between nationality and the weekly frequency of SSGs use for targeting sprint training (p = 0.019). The Chi-square test identified significant associations between nationality and the use of SSGs for targeting technical training (p = 0.002), as well as for tactical training (p = 0.002). In summary, this study underscores that SSGs are primarily employed to enhance aerobic fitness, change of direction, technical skills, and tactical behaviors. Coaches generally favor employing SSGs two to three times a week, with typical sessions lasting between 16 to 30 minutes. Notably, the major discrepancies between nationalities lie in the importance assigned to the use of SSGs. However, in practice, the formats and objectives for implementing SSGs remain relatively similar.

RÉSUMÉ

Partner preferences are an important differential in relationship formation and evolutionary fitness, and vary according to individual, ecological, and social factors. In this study, we evaluated the variation in preference for intelligence, kindness, physical attractiveness, health, and socioeconomic level among individuals of different sexes and sexual orientations in a Brazilian sample. We analyzed the preference scores of 778 heterosexual, bisexual, and homosexual men and women in three budgeted mate design tasks (low vs. medium vs. high budget) and their association with sociosexuality, attachment styles, homogamy, and willingness to engage in short- and long-term relationships. Results indicated a global trait preference order, with intelligence ranking first, followed by kindness, physical attractiveness, health, and lastly by socioeconomic status. Typical sex differences were observed mostly within the heterosexual group, and specific combinations of sex and sexual orientation were linked to variation in preference for physical attractiveness, kindness, and socioeconomic status. We also found unique associations of the other variables with partner preferences and with willingness to engage in short- or long-term relationships. By exploring the partner preferences of non-heterosexual individuals from a Latin American country, an underrepresented group in evolutionary psychology research, our results help understand the universal and specific factors that guide partner preferences and human sexual behavior.

RÉSUMÉ

Transfer learning is a machine learning technique that works well with chemical endpoints, with several papers confirming its efficiency. Although effective, because the choice of source/assistant tasks is non-trivial, the application of this technique is severely limited by the domain knowledge of the modeller. Considering this limitation, we developed a purely data-driven approach for source task selection that abstracts the need for domain knowledge. To achieve this, we created a supervised learning setting in which transfer outcome (positive/negative) is the variable to be predicted, and a set of six transferability metrics, calculated based on information from target and source datasets, are the features for prediction. We used the ChEMBL database to generate 100,000 transfers using random pairing, and with these transfers, we trained and evaluated our transferability prediction model (TP-Model). Our TP-Model achieved a 135-fold increase in precision while achieving a sensitivity of 92%, demonstrating a clear superiority against random search. In addition, we observed that transfer learning could provide considerable performance increases when applicable, with an average Matthews Correlation Coefficient (MCC) increase of 0.19 when using a single source and an average MCC increase of 0.44 when using multiple sources.

RÉSUMÉ

PURPOSE: Wheelchair users and people with disabilities have limited access to physical exercise due to various factors, including medical follow-up and training facilities. Although tele-exercise guided by experts has become a viable option, there is limited knowledge about the acute performance decrement (APD) resulting from remote training methods. The current cross-sectional study aimed to: (1) assess the APD of muscle resistance strength after three synchronous tele-exercise training methods in wheelchair users and (2) compare the training loads associated with each training method. MATERIALS AND METHODS: Eighteen male and female wheelchair users who participated in tele-exercise strength practices were recruited. The participants performed a maximum resistance strength test by synchronous tele-assessment (push-up test, PUT) at baseline and immediately after three training methods: high-intensity interval training (HIIT), moderate-intensity continuous training (MICT) and sprint interval training (SIT). The primary outcome was the APD, which was measured by the percentage decrease in the number of repetitions of the PUT immediately after the training methods. RESULTS: APD was observed for all three training methods, with no significant differences between them (-34.8%, -29.9% and -38.0% for MICT, SIT and HII, respectively), and presented a non-significant correlation with the training loads. HIIT had a significantly higher training load than MICT and SIT. CONCLUSIONS: APD occurred in all training sessions, but did not correlate with training load, indicating that it is not an appropriate metric for comparison. Findings provide insight into APD response and highlight the need to consider multiple metrics when comparing training protocols.


Synchronous moderate-intensity continuous training (MICT), sprint interval training (SIT) and high-intensity interval training tele-exercises provided similar acute performance decrement in wheelchair users and people with disabilities.High-intensity interval training showed a higher training load compared to MICT and SIT performed remotely.Acute performance decrement did not correlate with the training load.

RÉSUMÉ

OBJECTIVE: The aim of this study was to explore differences in brain activity and connectivity using simultaneous electroencephalography and near-infrared spectroscopy in patients with focal dystonia during handwriting and finger-tapping tasks. METHODS: Patients with idiopathic right upper limb focal dystonia and controls were assessed by simultaneous near-infrared spectroscopy and electroencephalography during the writing and finger-tapping tasks in terms of the mu-alpha, mu-beta, beta and low gamma power and effective connectivity, as well as relative changes in oxyhemoglobin (oxy-Hb) and deoxyhemoglobin using a channel-wise approach with a mixed-effect model. RESULTS: Patients exhibited higher oxy-Hb levels in the right and left motor cortex and supplementary motor area during writing, but lower oxy-Hb levels in the left sensorimotor and bilateral somatosensory area during finger-tapping compared to controls. During writing, patients showed increased low gamma power in the bilateral sensorimotor cortex and less mu-beta and beta attenuation compared to controls. Additionally, patients had reduced connectivity between the supplementary motor area and the left sensorimotor cortex during writing. No differences were observed in terms of effective connectivity in either task. Finally, patients failed to attenuate the mu-alpha, mu-beta, and beta rhythms during the finger-tapping task. CONCLUSIONS: Cortical blood flow and EEG spectral power differ between controls and dystonia patients, depending on the task. Writing increased blood flow and altered connectivity in dystonia patients, and it also decreased slow-band attenuation. Finger-tapping decreased blood flow and slow-band attenuation. SIGNIFICANCE: Simultaneous fNIRS and EEG may show relevant information regarding brain dynamics in movement disorders patients in unconstrained environments.

RÉSUMÉ

PURPOSE: To link the concepts measured by the Grocery Shelving Task Test (GST) to the codes and qualifiers of the activity and participation component of the International Classification of Functioning, Disability and Health (ICF). METHODS: The linkage was performed by two professionals who applied the 10 standardized binding rules. The linking process was performed through the model of extraction and identification of the concepts that were found in each item of the GST Test. RESULTS: The GST test includes 1 domain of the activity and participation component (d4 mobility). The link with the qualifiers allowed quantifying the impairment of the limitations of activities in the postoperative period, being observed that 21.27% of the sample did not present any problem, 61.70% presented the qualifier "0.1" (mild problem), 8.50% had a moderate problem (qualifier '0.2') and 8.50% had a severe problem (qualifier '0.3'). No complete impairment was observed in any study participant. DISCUSSION: The linking of the GST to the ICF codes and qualifiers allowed quantifying the functional impairment in the postoperative period of breast cancer, allowing a comprehensive and standardized view, and being a guiding tool for treatment plans.

RÉSUMÉ

To study linguistically coded concepts, researchers often resort to the Property Listing Task (PLT). In a PLT, participants are asked to list properties that describe a concept (e.g., for DOG, subjects may list "is a pet", "has four legs", etc.). When PLT data is collected for many concepts, researchers obtain Conceptual Properties Norms (CPNs), which are used to study semantic content and as a source of control variables. Though the PLT and CPNs are widely used across psychology, only recently a model that describes the listing course of a PLT has been developed and validated. That original model describes the listing course using order of production of properties. Here we go a step beyond and validate the model using response times (RT), i.e., the time from cue onset to property listing. Our results show that RT data exhibits the same regularities observed in the previous model, but now we can also analyze the time course, i.e., dynamics of the PLT. As such, the RT validated model may be applied to study several similar memory retrieval tasks, such as the Free Listing Task, Verbal Fluidity Task, and to research related cognitive processes. To illustrate those kinds of analyses, we present a brief example of the difference in PLT's dynamics between listing properties for abstract versus concrete concepts, which shows that the model may be fruitfully applied to study concepts.

RÉSUMÉ

This study aimed to identify the most important, frequently performed, and physically demanding tasks performed by Brazilian firefighters and to identify tasks that could be used to assess physical fitness. A subjective task analysis was conducted. Five hundred twenty-four firefighters (84% male; 16% females) responded to an online survey and rated 37 tasks across three domains (most important, most frequent, and most physically demanding). A dichotomous decision analysis was used to inform the proposed physical fitness tests. Wildland firefighting tasks presented the highest overall mean rate. Traffic control was considered the most important and frequently performed task. Lifeguard rescue was considered the most physically demanding task. The dichotomous analysis identified 14 essential tasks (seven structural firefighting and seven automobile accidents). The tasks identified may be helpful in developing criterion physical fitness tests and training programs related to firefighters' demands.Practitioner summary: The unpredictability, variability, and dangerousness of firefighting make it challenging to observe the physical demands imposed on firefighters. A subjective task analysis was conducted to identify essential tasks performed by Brazilian firefighters. Wildland firefighting, lifeguard rescue, automobile accidents, and structural firefighting tasks were the most important, frequent, and physically demanding.

RÉSUMÉ

Abstract Introduction: Gait is the motor task most impacted by amputation, requiring several physical and cognitive adaptations. The interaction between cognition and movement can be validly assessed through dual-tasks analysis. Objective: To analyze the kinematics of single and dual-motor tasks of participants with transfemoral amputation and compare it with healthy participants. Methods: This is a comparative cross-sectional study in which 14 participants in the transfemoral amputee group and 14 non-amputee participants attended the Gait Laboratory of the Clinical Center of the Universidade de Caxias do Sul to perform cognitive and motor activities tests. Speed, cadence, stride width, stride length, step length and step time were analyzed. Results: Participants in the transfemoral amputee group presented impaired gait kinematic parameters when compared to non-amputates during single and dual-tasks. Both groups showed a similar percentage decrease in performance on the dual-task compared to the single task. Conclusion: There is a distinction observed in the gait patterns and parameters of both groups, as evidenced in both the simple gait assessment and the dual-task evaluation. The primary finding of our study suggests that changes in gait kinematics appear to be exacerbated by dual-tasking rather than solely by amputation.


Resumo Introdução: A marcha é a tarefa motora mais impactada pela amputação, exigindo várias adaptações físicas e cognitivas. A interação entre cognição e movimento pode ser validamente avaliada por meio da análise de duplas tarefas. Objetivo: Analisar a cinemática de tarefas motoras simples e duplas de participantes com amputação transfemoral e compará-las com participantes saudáveis. Métodos: Estudo transversal comparativo no qual 14 participantes do grupo de amputados trans-femorais e 14 participantes não amputados compareceram ao Laboratório de Marcha do Centro Clínico da Universidade de Caxias do Sul para realizar testes de atividades cognitivas e motoras. Foram analisados a velocidade, cadência, largura do passo, comprimento do passo, comprimento da passada e tempo de passo. Resultados: Os participantes do grupo de amputados transfemorais apresentaram parâmetros cine-máticos da marcha prejudicados em comparação com os não amputados durante as tarefas simples e duplas. Ambos os grupos mostraram uma diminuição percentual semelhante no desempenho na tarefa dupla em comparação com a tarefa simples. Conclusão: Uma distinção pode ser vista nos padrões e parâmetros da marcha de ambos os grupos, e não apenas na avaliação simples da marcha, mas especialmente na avaliação da dupla tarefa. A principal descoberta do nosso estudo sugere que as mudanças nos parâmetros da cinemática da marcha pa-recem ser exacerbadas não só pela amputação, mas também pela realização de duplas tarefas.

RÉSUMÉ

Estímulos afetivos influenciam o comportamento devido a facilitações/inibições que ocorrem no sistema sensóriomotor. Para estímulos positivos, respostas ipsilaterais tendem a ser facilitadas e as contralaterais inibidas. Para estímulos negativos, o padrão é invertido. Atualmente, 34 voluntários foram submetidos à Tarefa de Compatibilidade Espacial Afetiva, cujos estímulos de valência inata foram as palavras "viver" e "morrer". No mapeamento 1, executaram-se respostas ipsilaterais para a palavra "viver" e respostas contralaterais para a palavra "morrer". No mapeamento 2, ocorreu o inverso. Através da análise temporal, investigamos se e como palavras que desencadeiam emoções inatas modulam a resposta motora. No mapeamento 1, constatamos respostas ipsilaterais mais lentas à palavra "viver" do que contralaterais à palavra "morrer" (a partir do 3º quintil). Porém, no mapeamento 2, houve diferença apenas no 3º quintil. Os efeitos facilitadores da resposta contralateral ao estímulo negativo estão possivelmente associados a mecanismos automáticos de vigilância para detectar/evitar estímulos de ameaça


Affective stimuli influence behavior due to facilitations/inhibitions that occur in the sensory-motor system. For positive stimuli, ipsilateral responses tend to be facilitated and contralateral inhibited. For negative stimuli, the pattern is reversed. Currently, 34 volunteers were submitted to the Affective Spatial Compatibility Task, whose innate valence stimuli were the words "living" and "dying". In mapping 1, ipsilateral responses were executed for the word "living" and contralateral for the word "dying". In mapping 2, the reverse occurred. Using temporal analysis, we investigated whether and how words that trigger innate emotions modulate the motor response. In mapping 1, we found slower ipsilateral responses to the word "living" than contralateral responses to the word "dying" (from the 3rd quintile). However, mapping 2 revealed a difference only in the 3rd quintile. The facilitating effects of the contralateral response to the negative stimulus are possibly associated with automatic vigilance mechanisms to detect/avoid threatening stimuli


Los estímulos afectivos influyen en el comportamiento debido a las facilitaciones/inhibiciones que se producen en el sistema sensoriomotor. Para los estímulos positivos, las respuestas ipsilaterales tienden a ser facilitadas y las contralaterales inhibidas. Para los estímulos negativos, el patrón se invierte. Actualmente, 34 voluntarios fueron sometidos a la Tarea de Compatibilidad Espacial Afectiva, cuyos estímulos de valencia innata fueron las palabras "vivir" y "morir". En el mapeo 1, se ejecutaron respuestas ipsilaterales para la palabra "vivir" y contralaterales para la palabra "morir". En el mapeo 2, ocurrió lo contrario. Mediante un análisis temporal, investigamos si las palabras que desencadenan emociones innatas modulan la respuesta motora y cómo lo hacen. En el mapeo 1, encontramos respuestas ipsilaterales más lentas a la palabra "vivir" que respuestas contralaterales a la palabra "morir" (del tercer quintil). Sin embargo, el mapeo 2 reveló una diferencia sólo en el 3er quintil. Los efectos facilitadores de la respuesta contralateral al estímulo negativo están posiblemente asociados a mecanismos automáticos de vigilancia para detectar/evitar estímulos amenazantes

RÉSUMÉ

We investigated postural stability through the margin of stability (MoS) while reaching and grasping an object with increasing difficulty levels in younger, fallers and non-fallers. Forty-five individuals distributed into three groups participated in this study: younger adults (YA), non-fallers (OA), and fallers (FOA). They stood upright and reached and grasped a dowel. Six conditions combining the stability of the dowel's base and obstacles close to the dowel were manipulated to characterize different difficulty levels. We computed the MoS in both anterior-posterior (AP) and medial-lateral (ML) directions in the interval between reaching onset and dowel contact. From the MoS time series, we analyzed the minimum and maximum, including the time of occurrence of these events. The MoS was smaller for OA than for YA in both directions. In the ML direction, the minimum MoS was smaller for FOA than for YA. The minimum MoS took place earlier for FOA than YA in the AP direction. FOA and OA exhibited similar behavior with reduced MoS, suggesting impaired postural control during reaching-to-grasping in a standing posture. FOA used a more cautious strategy by reverting the MoS earlier than YA, allowing them to increase their MoS before YA when preparing to grasp the dowel.

RÉSUMÉ

Introducción: Los intensivistas son gerentes asistenciales que toman decisiones en situaciones de estrés, por lo que su desempeño no solo depende del conocimiento técnico, sino también de las competencias gerenciales que alcancen. Objetivo: Identificar las competencias profesionales gerenciales para el desempeño de los intensivistas cubanos en la actualidad. Métodos: Se realizó una investigación de desarrollo con enfoque mixto, desde junio hasta octubre del 2021. Se emplean métodos teóricos y empíricos, entre los que se encuentran sujetos clave y un cuestionario en el que se pone a consideración de expertos, por método Delphi, las dieciséis competencias gerenciales del modelo por competencias profesionales del especialista en MIE, se utilizó Alfa de Cronbach y análisis de desligamiento multidimensional. Resultados: El Alfa de Cronbach global y por ítems del cuestionario resultó ser alto. En el análisis de desligamiento multidimensional resultó que, de las 16 competencias analizadas, diez se correlacionan entre sí y seis se disgregan del resto. Conclusión: Fueron identificadas tres competencias profesionales gerenciales con diez elementos de competencias imprescindibles para el desempeño de los especialistas en MIE y se evidencia que el desarrollo de la esfera gerencial es esencial en el desempeño de los intensivistas en la actualidad(AU)


Introduction: Intensivists are care managers who make decisions in stressful situations, so their performance not only depends on technical knowledge, but also on the managerial skills they accomplish. Objective: To identify the managerial professional proficiencies for the performance of Cuban intensivists nowadays. Methods: A development research was carried out with a mixed approach, from June to October 2021. Theoretical and empirical methods are used, among which are key individuals are considered beside a questionnaire assessed by experts, by Delphi method, sixteen managerial capabilities of the model by professional capabilities of a MIE specialist. Cronbach's Alpha and multidimensional disengagement analysis were used. Results: The global Cronbach's Alpha and by items of the questionnaire turned out to be high. In the multidimensional decoupling analysis, it turned out that, out of the 16 competencies analyzed, 10 are correlated with each other and six are disaggregated from the rest. Conclusion: Three managerial professional proficiencies were identified with 10 elements of essential proficiencies for the performance of MIE specialists and it is evident that the development of the managerial sphere is essential in the performance of intensivists these days(AU)
