RESUMO

(1) Background: Insufficient physical activity in adolescents remains an important issue for health promotion. Given the current relevance of understanding the adoption and maintenance of moderate and vigorous physical activity (MVPA), the aim of this study was to analyze, in a sample of adolescents, the role of grit personality as an antecedent of healthy eating and healthy weight (HEW) self-efficacy and its implications for the practice of MVPA. (2) Methods: Participants were 987 adolescents (597 girls, 390 boys) aged between 15 and 19 years from Mexico and Spain. The Spanish versions of the grit personality scale, the healthy eating and weight self-efficacy scale and the global physical activity questionnaire were used to measure the variables of interest. (3) Results: Mediated regression analysis showed that grit personality was not directly related to MVPA practice. However, the results indicate the significant relationship between grit personality and HEW self-efficacy, as well as the positive and significant relationship of this self-efficacy on MVPA practice. HEW self-efficacy totally mediated the relationship between grit personality and MVPA in both boys and girls. (4) Conclusions: These results suggest that having a grit personality (i.e., having interest and perseverance) is not enough for adolescents to be physically active, but that perceiving oneself as effective in having a healthy diet and healthy weight may be the key for adolescents to move more. At the intervention level, we suggest targeting an enhancement of young people's competence to eat healthily and regulate their weight as a strategy to enhance the performance of more MVPA, with a possible transfer between healthy behaviors (spill over).

RESUMO

Flexible work arrangements, such as teleworking, have gained massive and unprecedented usage for creating work environments that foster well-being and productivity. Yet empirical evidence is still scant and not much is known about the role of organizational climate(s) in this process. Accordingly, the present study was set out to investigate the mediating mechanisms linking flexible teleworking to scientific productivity by considering climate for well-being dimensions, the climates for excellence and for innovation, and eudaemonic well-being as mediating constructs. Data were collected from 358 members of 48 Spanish European Research Council (ERC) granted teams and analyses were conducted both at the individual and team level, after checking for the relevant aggregation indexes. Relevant and significant relations were found within the hypothesized statistical model both at the individual and team level of analysis. The climate dimension of team support and the climate for innovation, together with eudaimonic well-being, resulted to be linked by significant relationships suggesting a potential mediating path. Also, empirical evidence supported considering gender as a control variable for the relationship between flexible teleworking and the climate dimension of work-life balance. In conclusion, climate variables and eudaimonic well-being represent relevant variables for the explanation of the relationship between flexible teleworking and scientific productivity. Practical and theoretical implications, and limitations are further discussed in the article.

RESUMO

Dedifferentiation is the process by which terminally differentiated cells acquire the properties of stem cells. During mouse skin wound healing, the differentiated Gata6-lineage positive cells of the sebaceous duct are able to dedifferentiate. Here we have integrated lineage tracing and single-cell mRNA sequencing to uncover the underlying mechanism. Gata6-lineage positive and negative epidermal stem cells in wounds are transcriptionally indistinguishable. Furthermore, in contrast to reprogramming of induced pluripotent stem cells, the same genes are expressed in the epidermal dedifferentiation and differentiation trajectories, indicating that dedifferentiation does not involve adoption of a new cell state. We demonstrate that dedifferentiation is not only induced by wounding, but also by retinoic acid treatment or mechanical expansion of the epidermis. In all three cases, dedifferentiation is dependent on the master transcription factor c-Myc. Mechanotransduction and actin-cytoskeleton remodelling are key features of dedifferentiation. Our study elucidates the molecular basis of epidermal dedifferentiation, which may be generally applicable to adult tissues.

RESUMO

Abstract Introduction: Ethical culture stands out as an important variable in comprehending ethical norms and ethical behaviour at work. The Corporate Ethical Virtues (CEV) Scale is a widely used measure of ethical culture in organisations. This study aimed to adapt and validate the CEV Scale to a Brazilian context. Method: In Study 1 (n = 1.219), the CEV Scale was translated and adapted, the reliability and the internal structure were tested and the discriminant validity of ethical climate measures was demonstrated. In Study 2 (n = 635), measurement invariance in two groups was demonstrated, and there was evidence of validity based on the relationships with related constructs. Results: The results indicated that the Brazilian version of the CEV Scale showed reasonable psychometric properties and provided evidence of convergent and discriminant validity. Conclusion: This measure can be used by managers and consultants to diagnose ethical organisational culture.


Resumen Introducción: La cultura ética se destaca como una variable importante para comprender las normas y el comportamiento éticos en el trabajo.

RESUMO

Resumen Introducción: El objetivo principal de este trabajo es conocer la interrelación entre la percepción de los climas empowering y disempowering generados por los entrenadores (nivel equipo) con la satisfacción y frustración de las necesidades psicológicas básicas, y estas, a su vez, con las intenciones de continuar y abandonar la práctica deportiva (nivel individual) en jóvenes deportistas. Método: Participaron 251 deportistas mexicanos (M = 13.22, DT = 1.28) pertenecientes a 19 equipos. Se les aplicó una batería de cuestionarios para la recolección de datos y se realizó un análisis multinivel de ecuaciones estructuradas. Resultados: El modelo de ecuaciones estructurales reveló asociaciones positivas entre las percepciones de climas empowering desde una perspectiva grupal sobre la satisfacción de necesidades psicológicas básicas y de estas sobre las intenciones de continuar la práctica deportiva desde una perspectiva individual, así como entre las percepciones de un clima disempowering sobre la frustración de las necesidades psicológicas básicas y de estas sobre las intenciones de abandono. Conclusión: Los hallazgos de este estudio sugieren en un nivel aplicado que el clima empowering actúa como catalizador del bienestar psicológico y como protector de la aparición de frustración, mientras que el clima disempowering facilita el desarrollo de respuestas psicológicas desadaptativas en el deporte.


Abstract Introduction: The main objective of this work is to know the interrelation between the perception of empowering and disempowering climates generated by coaches (team level) with basic psychological needs satisfaction and frustration, and these in turn, with the intentions to continue and abandon sports practice (individual level) in young athletes. Method: 251 Mexican athletes participated (M = 13. 22, SD = 1.28) belonging to 19 teams. A battery of questionnaires was applied for data collection and a multilevel structured equation analysis was performed. Results: The structural equation model revealed positive associations between perceptions of empowering climates from a group perspective on the satisfaction of basic psychological needs and of these on intentions to continue practicing sports from an individual perspective; as well as between perceptions of a disempowering climate on the frustration of basic psychological needs and of these on intentions to drop out. Conclusion: The findings of this study suggest at an applied level that the empowering climate acts as a catalyst of psychological well-being and as a protector against the occurrence of frustration, while the disempowering climate facilitates the development of maladaptive psychological responses in sport.

RESUMO

On the basis of the spillover or transfer effect and the transtheoretical model of change, this study assessed the association between amount of physical activity, healthy and unhealthy weight control behaviors, and motivational types, as well as their variability across stages of change. A total of 1219 randomly selected Mexican adults from 18 to 65 years old, representative of the city of Monterrey (México), participated in the study. Correlation analyses, differences by gender, and multivariate analyses of variance, controlling for age, were performed. We found that in the maintenance stage, there is higher frequency of physical activity more healthy weight control behaviors, as well as higher autonomous motivation. In the contemplation stage, there is less physical activity, a higher frequency of unhealthy weight control behaviors, higher controlled motivation, and amotivation. Relationships were found between the healthy behaviors studied and the interaction dynamics observed across the stages of change, highlighting the key role of the contemplation and maintenance stages in weight control change. Physical activity as a targeted intervention objective could be a gateway to healthier weight control behavior, as well as higher autonomous motivation.

RESUMO

Based on the conceptual model of multidimensional and hierarchical motivational climate the objective of this study was to test two models. One model (M1) of total mediation, testing the mediating mechanisms that explain why the motivational climate affects intention of continuity or dropout. Specifically, we test the mediating role of satisfaction/frustration of basic psychological needs and self-determined motivation, in the relationship between the players' perception of the empowering and disempowering climate created by the coach, and the intention of young soccer players to continue/dropout the sport practice. The second model (M2) of partial mediation, contributes to knowing the mechanisms that link the antecedent variables included in the model (perceived empowering and disempowering motivational climate) and the outcomes (intention of continuity or dropout in sport). A total of 381 young male soccer players between 12 and 14 years of age (M = 12.41, SD = 0.89), completed a questionnaire package tapping into the variables of interest: players' perception of the motivational climate created by the coach (empowering and disempowering), satisfaction/thwarting of basic psychological needs, self-determined motivation and the intention to continue/dropout sports participation. The hypothesized model was tested using a structural equation model technique with latent variables. The results of the partial mediation model were satisfactory (χ2= 120.92; df = 68; RMSEA = 0.045; CFI = 0.968; TLI = 0.957) and showed that need satisfaction and self-determined motivation partially mediated the relationship between the perception of the empowering climate and the intention to continue. Moreover, need satisfaction showed a positive and significant relationship with the intention to continue sports participation. Additionally, need thwarting and self-determined motivation totally mediated the relationship between the perception of the disempowering climate and the intention to dropout. Furthermore, needs thwarting was positively and significantly related to the intention to dropout of sports participation. Findings point to the importance of fostering empowering climates and preventing the creation of disempowering climates in the grassroots football.

RESUMO

OBJECTIVE: To understand the psychological antecedents or personal factors that lead to weight control behaviours that can help to develop more effective prevention strategies. DESIGN: The present correlational study has a non-experimental, quantitative, cross-sectional design. A model was tested considering types of motivation (autonomous motivation, controlled motivation and amotivation) as mediators in the relationship between the Grit personality and healthy and unhealthy weight control behaviours, with self-control as a moderator in the aforementioned indirect effects. SETTING: Monterrey (Nuevo León, México). PARTICIPANTS: A representative sample of 1219 adults (men = 599; women = 620) aged 18-65 years (M = 29·37, sd = 11·83). RESULTS: Findings supported the mediator role of the types of motivation. Specifically, Grit showed a positive indirect effect on healthy weight control behaviours through autonomous motivation. Conversely, Grit showed a negative indirect effect on unhealthy weight control behaviours through autonomous motivation. Furthermore, findings supported the moderator role of self-control in the relationship between amotivation and healthy and unhealthy weight control behaviours. CONCLUSIONS: This study provides evidence for the key role of Grit in the adoption of healthy or unhealthy control behaviours, as well as the role of autonomous motivation in the development of healthy behaviours.

RESUMO

The teacher's instructions in physical education class have important implications for the psychological well-being of their students. The aim of this study was to analyze, under the postulates of the Self-Determination Theory (SDT), a model with the following sequence: the perception of the quality of the instructions (task presentation, amount of corrective feedback, and its legitimate perception) generated by the physical education teacher, the satisfaction of the three basic psychological needs and the subjective vitality in young students. The participants were 890 students (462 males and 428 females) of primary level from the metropolitan area of Monterrey, Mexico, between ages 11 and 13 (M = 11.36; SD = 0.49). The structural equation modeling showed positive and significant associations in all model interrelations, that is, task presentation and the amount of corrective feedback (B = 0.88, p < 0.001), and this in turn with legitimate perception (B = 0.81, p < 0.001); the legitimate perception of feedback and the satisfaction of the need for autonomy, competence, and relatedness (B = 0.63, p < 0.001; B = 0.90, p < 0.001; B = 1.01, p < 0.001, respectively); finally, the satisfaction of the three psychological needs and the subjective vitality (B = 0.12, p < 0.01; B = 0.43, p < 0.001; B = 0.24, p < 0.001, respectively). Therefore, the importance of a quality task presentation, as well as providing corrective feedback based on support for autonomy, is evident, so that students perceive it legitimately and thus facilitate the satisfaction of their basic psychological needs and in consequence, indicators of psychological well-being such as subjective vitality.

RESUMO

Peer victimization and dating violence victimization have serious negative effects on adolescents' health, and they seem to be related. However, the mediating processes in this relationship have not been sufficiently analyzed. The purpose of this study was to analyze the direct and indirect relationships between peer victimization and dating violence victimization, considering the possible mediator role of loneliness, depressed mood, and life satisfaction. These relationships are analyzed in boys and girls, and in early and middle adolescence. From an initial sample of 1,038 Spanish adolescents, those who had or had had in the past 12 months a dating relationship (647 adolescents; 49.1% boys, M = 14.38, SD = 1.43) were included in this study. Multigroup structural equation modeling was used to test a double mediation model simultaneously for boys and girls, testing the invariance of the relationships among variables across genders. The same technique was used to test the model simultaneously for early and middle adolescence, testing the invariance of the relationships among variables across age groups. Results revealed a positive direct relationship between peer victimization and dating violence victimization, as well as the partial mediating role of loneliness and life satisfaction in this relationship. The mediator role of depressed mood was not supported. The same mediational model was confirmed in boys and girls, and in early and middle adolescence. These results highlight the important role of loneliness and life satisfaction to explain the link between peer victimization and dating violence victimization in adolescence. These findings may be useful for developing intervention programs aimed at preventing situations of multiple victimization during adolescence.

RESUMO

Athletes have to face several challenges during the sport season, and one of them could involve dealing with unattainable goals. In these situations, being able to reengage in other goals as a form of goal adjustment and in response to contextual demands is adaptive. According to previous literature, some aspects of the athletes' social context, such as coach-created motivational climates, could encourage more adaptive responses in athletes, and so it is possible that these climates would also promote athletes' goal regulation and goal reengagement. The purpose of this study was twofold: to analyze whether athletes' perception of empowering and disempowering climates were related to their goal reengagement through the mediation of goal motives; and to examine the interaction between the two climates when they predict reengagement through athletes' goal motives. Participants were 414 Spanish university athletes (49.5% male, 50.5% female) who belonged to different university teams, with ages ranging from 17 to 33 years old (M = 20.61, SD = 2.58). In the sport facilities, all of them completed questionnaires that evaluated their perception of empowering and disempowering climates, their goal motives, and their goal reengagement. Structural equation modeling (SEM) results showed that perceived empowering climate positively predicted autonomous goal motives, which in turn had a positive relationship with goal reengagement. Conversely, perceived disempowering climate positively predicted controlled goal motives, which were not related to goal reengagement. Thus, we only found support for the indirect relationship between perceived empowering climate and goal reengagement through autonomous goal motives. Moderated mediation analyses revealed that interaction effects between perceived empowering and disempowering climates were not significant in the prediction of goal reengagement through goal motives. Findings revealed that the perception of empowering climates promotes athletes' goal reengagement when goals become unattainable via the increase in their autonomous goal motives. Conversely, when athletes perceive disempowering climates, they have more controlled goal motives, which are not related to goal reengagement. In addition, the study supports the need to educate coaches to create more empowering and less disempowering climates.

RESUMO

Job quality is critical for policy makers, but little is known about the factors that shape perceived job quality among employees. This study aimed to explore the importance of several traditional job quality indicators: employment characteristics (type of contract, employment relationship, schedule predictability) and educational misfit (horizontal, vertical) in predicting perceived job quality. Additionally, the moderating roles of preferred employment characteristics and gender were tested. A hierarchical multiple regression analysis was conducted in a sample of 562 Spanish employees. The results demonstrated that all the indicators, except schedule predictability, were related (and contributed equally) to perceived job quality. Gender moderated the interaction effect between the current and preferred employment relationship. For women, the full-time preference boosted the effect of full-time jobs on perceived job quality, whereas for men, the part-time preference boosted this effect. The findings indicate the importance of adopting a contextual approach to perceived job quality, considering individuals’ preferred employment characteristics and gender.


A qualidade do trabalho é crítica para os formuladores de políticas, mas pouco se sabe sobre os fatores que moldam a percepção da qualidade do trabalho entre os funcionários. Este estudo teve como objetivo explorar a importância de vários indicadores tradicionais de qualidade do emprego: características do emprego (tipo de contrato, relação de trabalho, previsibilidade de horário) e desajuste educacional (horizontal, vertical) na previsão da qualidade percebida do emprego. Além disso, os papéis moderadores de características de emprego preferenciais e gênero foram testados. Uma análise de regressão múltipla hierárquica foi realizada em uma amostra de 562 funcionários espanhóis. Os resultados demonstraram que todos os indicadores, exceto a previsibilidade do cronograma, estavam relacionados (e contribuíam igualmente) para a qualidade percebida do trabalho. O gênero moderou o efeito da interação entre a relação de trabalho atual e a preferencial. Para as mulheres, a preferência de tempo integral impulsionou o efeito dos empregos de tempo integral na percepção da qualidade do trabalho, enquanto para os homens, a preferência de meio período aumentou esse efeito. Os resultados indicam a importância de adotar uma abordagem contextual para a percepção da qualidade do trabalho, considerando as características de emprego preferidas dos indivíduos e gênero.

Para las mujeres, la preferencia a tiempo completo impulsó el efecto de los trabajos a tiempo completo sobre la calidad percibida del trabajo, mientras que para los hombres, la preferencia a tiempo parcial aumentó este efecto. Los hallazgos indican la importancia de adoptar un enfoque contextual de la calidad del trabajo percibida, considerando las características laborales preferidas de las personas y el género.

RESUMO

The way students perceive corrective feedback has repercussions on what they learn and think. Based on the self-determination theory, the aim of this study is to test a model of multilevel mediation that examines the relationships between the perception of corrective feedback with its degree of acceptance (perceived legitimacy) at the team level and the subjective vitality of students at the individual level, mediated by the satisfaction of the three psychological needs, in the context of physical education. The participants were 742 students aged between 10 and 13 years old (52.6% men, 47.4% women) in 29 physical education groups. The results of the multilevel structural equation modeling analysis found at the group (between) level a positive and significant relationship between corrective feedback and perceived legitimacy (B between = 0.49, p < 0.01), as well as a positive and significant relationship between perceived legitimacy and the needs of competence (B between = 0.66, p < 0.05) and relatedness (B between = 0.95, p < 0.01). In addition, there was a positive and significant association between competence and subjective vitality (B between = 2.06, p < 0.01), and a negative and significant association between relatedness and subjective vitality (B between = -0.85, p < 0.01). Also, on an individual (within) level, the needs of autonomy (B within = 0.09, p < 0.05), competence (B within = 0.27, p < 0.01), and relatedness (B within = 0.17, p < 0.01) were positively and significantly associated with subjective vitality. Finally, corrective feedback showed a positive indirect effect on subjective vitality through perceived legitimacy and competence, while the indirect effect was negative through perceived legitimacy and relatedness. In conclusion, on an individual level, students who perceive their basic psychological needs to be met in turn, increase their subjective vitality. At the group level, the results are discussed. These findings suggest that teachers might be best advised to ensure that their students accept corrective feedback, by having it couched in a manner that suggests that learning and improvement can follow, and communicated in an autonomy-supporting way.

RESUMO

To establish whether 4-nitroquinoline N-oxide-induced carcinogenesis mirrors the heterogeneity of human oral squamous cell carcinoma (OSCC), we have performed genomic analysis of mouse tongue lesions. The mutational signatures of human and mouse OSCC overlap extensively. Mutational burden is higher in moderate dysplasias and invasive SCCs than in hyperplasias and mild dysplasias, although mutations in p53, Notch1 and Fat1 occur in early lesions. Laminin-α3 mutations are associated with tumour invasiveness and Notch1 mutant tumours have an increased immune infiltrate. Computational modelling of clonal dynamics indicates that high genetic heterogeneity may be a feature of those mild dysplasias that are likely to progress to more aggressive tumours. These studies provide a foundation for exploring OSCC evolution, heterogeneity and progression.

RESUMO

Currently, cyber dating violence (CDV) is a serious health problem among adolescents due to their frequent use of communication technologies in their romantic relationships including the use of these technologies to perpetrate dating violence. However, research on this topic is recent and more studies about victims' psychosocial adjustment are needed. The objectives of this study were to analyze the prevalence of CDV victimization according to frequency (occasional and frequent) and type (cyber control and cyber-aggression) and to explore their relations with loneliness, depressive mood and cyberbullying victimization. A total of 604 adolescents (M age = 14.32, SD = 1.67) who had a dating relationship at the time or in the past 12 months, participated in this study. The results showed a higher prevalence for cyber-control than cyber-aggression victimization, and positive correlations of CDV victimization with depressive mood and cyberbullying victimization in boys and girls. Positive correlations with loneliness were also observed for girls. The average effect size of the aforementioned correlations was large for girls and medium for boys. Both boys and girls who were frequent victims of CDV also suffered more cyberbullying by peers than those who were never, and occasionally, cyber victimized by their partners. Girls who were frequent victims of CDV also reported higher scores for loneliness and depressive mood, with a small average effect size. All these results highlight close relations between cyberbullying and CDV in adolescents, being necessary to pay greater attention to possible experiences of poly-victimization, and a worse psychosocial adjustment in frequently victimized girls than boys. These findings may be useful for developing more effective intervention programs.

RESUMO

To achieve their goals, organizations for individuals with intellectual disability have to stimulate high-quality relationships between professionals and family members. Therefore, achieving professionals' trust in family members has become a challenge. One relevant factor in explaining professional's trust in families is the degree to which family members use the "problem-solving" conflict management strategy (high concern for oneself but also for the other party) in their disputes-disagreements with professionals. It is reasonable to argue that when family members use problem-solving conflict management, professionals' trust increases. Professionals' trust, in turn, stimulates the use of problem-solving strategies by family members. However, it is also plausible that professionals are the initiators of this positive spiral (professionals' trust-problem-solving conflict management by family members-professionals' trust). To examine this relationship between problem solving and trust over time, we conducted a longitudinal survey study in which 329 professionals reported on these two constructs three times (with 4 weeks between the measurements). Using structural equation modeling, we compared four nested models: (a) stability, (b) causality (where the problem-solving strategy by familiar members is the initiator of the spiral), (c) reversed causation (where the professional's trust is the initiator of the spiral), and (d) reciprocal (where problem-solving conflict management and trust reinforce each other). The results of the χ2 difference tests, regarding the comparison of the models, showed that the reciprocal model was significantly superior to the alternative proposals. Our findings supported a complex view of the relationships between problem-solving conflict management and trust, based on dynamic reciprocal relationships over time.

RESUMO

The lockdown resulting from coronavirus disease 2019 (COVID-19) has had a huge impact on peoples' health. In sport specifically, athletes have had to deal with frustration of their objectives and changes in their usual training routines. The challenging and disruptive situation could hold implications for their well-being. This study examined the effect of the COVID-19 lockdown on changes in athletes' reported eudaimonic well-being (subjective vitality) and goal motives (autonomous and controlled) over time (i.e., pre-lockdown and during lockdown). The relationship of resilience to changes in subjective vitality was also determined, and changes in athletes' goal motives were examined as potential mediators. Participants were 127 Spanish university athletes aged between 18 and 34 years (M = 21.14; SD = 2.77). Approximately 4 months before the start of the lockdown in Spain (T1), athletes responded to a questionnaire assessing their resilience, goal motives, and subjective vitality. Around 6 months later into the lockdown period (T2), athletes' goal motives and subjective vitality were assessed again. Growth modeling using hierarchical linear models revealed a significant decrease of autonomous goal motives and subjective vitality during the lockdown, but athletes did not show change over time in controlled goal motives. Path analysis, adjusting T2 measures for their corresponding T1 measures, showed that resilience significantly predicted changes in athletes' autonomous goal motives, which then accounted for changes in subjective vitality. The indirect effect was significant. Resilience did not predict changes in athletes' controlled goal motives. However, changes in controlled goal motives negatively predicted changes in subjective vitality during lockdown. The findings suggest negative impacts of the COVID-19 lockdown on athletes' goal motives and eudaimonic well-being. Results also support the hypothesized mediational role of autonomous goal motives in the relationship between resilience and subjective vitality during the lockdown. As such, findings confirm the relevance of resilience to a key feature of athletes' eudaimonic well-being and the importance of enhancing their autonomous goal striving.

RESUMO

INTRODUCTION: Mindful organizing (also known as collective mindfulness) is a team level construct that is said to underpin the principles of high-reliability organizations (HROs), as it has shown to lead to almost error-free performance. While mindful organizing research has proliferated in recent years, studies on how to measure mindful organizing are scarce. Vogus and Sutcliffe (2007) originally validated a nine-item "Mindful Organizing Scale" but few subsequent validation studies of this scale exist. The present study aimed to validate a Spanish version of the Mindful Organizing Scale. METHOD: The sample included 47 teams (comprising of a total of 573 workers with an average team size of 12.19) from a Spanish nuclear power plant. A confirmatory factor analysis (CFA), reliability analysis, and an analysis of aggregation indices were carried out. A correlation analysis and CFA were used to further validate the scale in terms of its distinctiveness from, and relationship with, other team-related variables such as safety culture, team safety climate, and team learning. Finally, evidence of criterion-related validity was collected by testing the incremental validity of the mindful organizing scale in the association with various workplace safety outcomes (safety compliance and safety participation). RESULTS: The results confirmed a unidimensional structure of the scale and indicated satisfactory internal consistency. Aggregation of the scores to the team level was justified while significant positive correlations between mindful organizing and other team-related variables (safety culture, team safety climate, team learning) were found. Moreover, mindful organizing showed distinctiveness from safety culture, team safety climate and team learning. Finally, incremental validity of the scale was supported, as it shows to be associated with safety compliance and safety participation above and beyond other related constructs. CONCLUSIONS: The Spanish version of the Mindful Organizing Scale has shown to be a valid and reliable scale that can be used to measure mindful organizing. CONTRIBUTIONS: The validation of the unidimensional Spanish version of Vogus and Sutcliffe's (2007) Mindful Organizing Scale provides researchers and practitioners with a reliable and valid tool to use in Spanish speaking organizations to measure mindful organizing, which has been shown to result in more reliable performance. Theoretically, this study offers four contributions. Firstly, it validates a scale that operationalizes the 'mindful organizing' construct in a traditional high-reliability organization (nuclear power plant) which has never been done before. Secondly, it offers evidence that a mindful organizing scale can be validated in a new cultural context and language (Spanish) to any of the previous studies done before it. Thirdly, it adds to our understanding of mindful organizing's nomological network by distinguishing it from other team and safety-related variables. Lastly, it builds on current research showing sound psychometric properties of a one-dimensional, quantitative measure of mindful organizing.

RESUMO

Despite the well-known positive consequences of transformational coaches in sport, there is still little research exploring the mechanisms through which coaches' transformational leadership exerts its impact on athletes. Multilevel SEM was used to examine the relationship between coaches' transformational leadership style, a task-involving climate, and leadership effectiveness outcome criteria (i.e., players' extra effort, coach effectiveness, and satisfaction with their coach), separately estimating between and within effects. A representative sample of 625 Spanish male soccer players ranging from 16 to 18 years old and nested in 50 teams completed a questionnaire package tapping the variables of interest. Results confirmed that at the team level, team perceptions of transformational leadership positively predicted teams' perceptions of task climate, which in turn positively predicted the three outcome criteria. At the individual level, players' perceptions of transformational leadership positively predicted teams' perceptions of task climate, which in turn positively predicted teams' extra effort and coach effectiveness. Mediation effects appeared at the team level for all the outcome criteria, and at the individual only for extra effort. Transformational leadership is recommended to enhance task climate, in order to increase players' extra effort, their perceptions of the effectiveness of their coach, and their satisfaction with his/her leadership style.
