Coach autonomy support and quality of sport engagement in young soccer players

Based on the self-determination theory (Ryan & Deci, 2000), this study tested a model of the assumed sequential relationships between perceived autonomy support, psychological need satisfaction, self-determined motivation, and enjoyment/boredom. The hypothesized mediational roles of psychological need satisfaction and self-determined motivation were also studied. In a sample of 370 young male soccer players, path analysis results offered support for the proposed model. Total mediation was supported in the case of the psychological need satisfaction in the relationship between autonomy support and self-determined motivation, and partial mediation for self-determined motivation in the links between psychological need satisfaction and enjoyment (positive) and boredom (negative). Implications of autonomy-supportive behaviors provided by coaches for the quality of sport involvement among young athletes are discussed.Alvarez, Maria Soledad; [email protected]; [email protected]

Oral lichenoid lesions related to contact with dental materials: A literature review

Oral lichenoid lesions related to contact are defined as oral-cavity eruptions with an identifiable etiology, and are clinically and histologically similar to oral lichen planus. Within this group are found oral lichenoid lesions related to contact with dental materials (OLLC), the most common being those related to silver amalgam. Currently, it remains difficult to diagnose these lesions due to the clinical and histopathological similarity with oral lichen planus and other oral mucosa lesions of lichenoid characteristics. In the present paper, we carry out an updated review of the tests for, and the different characteristics of OLLC, which may aid the diagnosis. For this review, we made searches in the Pubmed® and Cochrane® databases. Among the literature we found several published papers, from which we have used review papers, case papers, cohort studies, case and control studies, and a meta-analysis study. After carrying out this review, we can conclude that the diagnosis of these lesions is still difficult and controversial. However, there are different aspects in the clinical presentation, pathological study and results obtained when replacing suspect materials, which, when taken together, may be useful when establishing the final diagnosis of OLLC

Physical activity, healthy behaviors and its motivational correlates: exploring the spillover effect through stages of change

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 motivatio

Determinants of leisure-time physical activity and future intention to practice in Spanish college students

Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and women. The practice of physical activity has also a direct effect on future intention to practice. Likewise, the participation in sport competitions predicts practice of physical activity and future intention in men, whereas being a member of a sports club predicts practice and future intention in [email protected]; [email protected]

Examining the mediating role of motivation in the relationship between multidimensional perfectionism and well- and ill-being in vocational dancers.

: Perfectionism is considered to be an important personality factor within the dance context given the high number of dancers whose psychological health is influenced by its consequences. The relationship between perfectionism and dancers' well- and ill-being can be mediated by a range of variables. The present study explores the role of forms of motivation (i.e., autonomous motivation, controlled motivation and amotivation) as mediators in the relationship between perfectionism (i.e., self-oriented and socially prescribed) and an indicator of well-being (i.e., subjective vitality) and ill-being (i.e., burnout). Participants of the study were 146 male and female Spanish vocational dancers aged between 12 and 26 years old (Mean age = 15.40 ± 2.96) who completed questionnaires measuring the variables of interest. Results of multiple mediator regression analyses showed that amotivation mediated the relationships between self-oriented and socially prescribed perfectionism with burnout and subjective vitality. Self-oriented perfectionism was negatively correlated, and socially prescribed perfectionism positively associated with amotivation. Amotivation of dancers was a positive predictor of burnout and a negative predictor of subjective vitality. Overall, the findings corroborate the importance of amotivation in the relationship between perfectionism dimensions and well-being and ill-being in dancers

Romantic myths and cyber dating violence victimization in Spanish adolescents: A moderated mediation model.

Adolescents' beliefs in romantic myths of love have been related to cyber dating violence victimization. However, these relationships could be mediated by adolescents' tolerant attitudes toward dating abuse and be different for adolescent boys and girls. A better understanding of these relationships is important for developing more effective prevention programs. Thus, the current study aimed to examine the relationships between beliefs in romantic myths and cyber dating violence victimization in adolescents, analyzing the possible mediating role of tolerant attitudes toward abuse and the possible moderator role of gender. Participants were 467 Spanish adolescents who had a romantic relationship (54.4% girls; M age = 15.09). Results showed positive significant direct and indirect relationships, through tolerant attitudes toward abuse, between beliefs in romantic myths and cyber dating violence victimization. Gender was not a moderator variable in the direct relationships, but its moderator role was supported in the indirect relationships. Stronger positive links between romantic myths and tolerant attitudes toward abuse, and between tolerant attitudes and cybercontrol victimization, were found in adolescent girls. These findings highlight the need to consider tolerant attitudes toward abuse in intervention programs designed to prevent cyber dating violence victimization in adolescents and continue to analyze gender differences in variables related to cyber dating violence victimization

Los entrenadores como promotores de la cohesión del equipo

Resumen: El objetivo del presente trabajo fue triple: 1) Estudiar las relaciones entre el clima motivacional percibido creado por el entrenador y la cohesión, 2) Poner a prueba un modelo con la siguiente secuencia: dimensiones del clima motivacional percibido motivación autodeterminada dimensiones de la cohesión, y 3) Estudiar el papel mediador de la motivación autodeterminada entre el clima motivacional percibido y la cohesión. Ochocientos nueve jóvenes jugadores de fútbol (798 chicos y 11 chicas; M = 11.49, DT = 1.16) completaron un paquete de cuestionarios en los que se evaluaban las variables de interés al principio de la temporada. Las correlaciones bivariadas informaron de relaciones positivas entre la percepción del clima de implicación en la tarea y ambas dimensiones de cohesión (tarea y social), mientras que el clima de implicación en el ego presentó correlaciones negativas con la cohesión de tarea. Los resultados del modelo de ecuaciones estructurales informaron que el clima-tarea se asoció positivamente con la motivación autodeterminada, mientras que el clima-ego lo hizo en sentido negativo. La motivación autodeterminada se relacionó de forma positiva tanto con la cohesión de tarea como con la cohesión social. Finalmente, la motivación autodeterminada actuó como mediador parcial entre el clima de implicación en la tarea y ambas dimensiones de la cohesión, y de mediador total entre el clima de implicación en el ego y la cohesión (tarea y social). Se enfatizan las implicaciones de las conductas de los entrenadores para la construcción de la cohesión en los equipos y para el desarrollo de la calidad de la motivación

Do active commuters feel more competent and vital? A self-organizing maps analysis in university students

University students represent a population that faces high risks regarding physical inactivity. Research suggests that a regular engagement in physical activity (PA) may be more likely established when it leads to the experience of subjective vitality. Subjective vitality, in turn, is more likely achieved through physical activities that individuals feel competent in, and that take place in natural outdoor environments. An activity that may fulfill these conditions is active commuting to and from university (ACU). To examine whether and in which form ACU can combine this promising pattern of aspects, a person-oriented analysis was conducted. The sample contained 484 university students (59.3% females). Leisure-time PA, ACU by walking, ACU by cycling, subjective vitality, PA-related competence and body mass index were included as input variables in a self-organizing maps analysis. For both female and male university students, the identified clusters indicated that students who intensively engaged in ACU did not exhibit subjective vitality levels above average. Consistently, they did not show elevated levels of PA-related competence, which suggests that ACU does not support the perception of their physical abilities. Considerations regarding urban university environments lacking sufficient natural elements finally add to the conclusion that engaging in ACU does not suffice to establish a vitality-supportive and thus sustainable PA behavior. Additionally, the identified clusters illustrate a large heterogeneity regarding the interaction between leisure-time PA, body mass index and subjective vitality

La aceptación familiar y la conducta prosocial: el rol de los factores de personalidad en menores con medidas de internamiento judicial

En la presente investigación se analiza la relación entre el sentimiento de aceptación familiar y las distintas dimensiones de la conducta prosocial en menores infractores en régimen de internamiento. El interés está también en determinar el rol mediador y moderador que tienen los factores de personalidad (modelo de los “cinco grandes”) en la relación entre el sentimiento de aceptación familiar y la conducta prosocial. La muestra está formada por 162 menores infractores con edades entre los 14 y los 22 años (M = 17.10, DT = 1.41), con medida judicial de internamiento en centros de la Comunidad Autónoma de Madrid (España). Los resultados obtenidos indican que no hay una relación directa entre el sentimiento de aceptación familiar y las distintas dimensiones de la conducta prosocial, pero sí efectos indirectos a través de los factores de personalidad de estabilidad emocional y responsabilidad (conciencia). Así, los datos sugieren que la estabilidad emocional tiene un rol mediador en la relación entre el sentimiento de aceptación familiar y la conducta prosocial en sus dimensiones de altruismo y conducta anónima y la responsabilidad (conciencia) un rol moderador. Este trabajo pone de manifiesto la importancia de la familia en el desarrollo positivo de los rasgos de responsabilidad y estabilidad emocional de los hijos, siendo estos rasgos de personalidad las variables con efecto directo en las conductas de prosocialidad en menores con medidas judiciales de internamiento.This research analyses the existing relationship between feeling of familiar acceptance and dimensions of prosocial behaviour in underaged offenders under a detention regime. Attention must be also paid to determining the mediator and moderator role played by personality factors (Big Five model) in the relationship between family acceptance and prosocial behaviour. The sample consisted of 162 underaged offenders aged between 14 and 22 (M = 17.10, SD = 1.41), who are serving a judicial measure of detention in centres located in Madrid Region, Spain. The results show that although there is no direct relation between feeling of family acceptance and different dimensions of prosocial behaviour, indirect effects showed through personality factors of emotional stability and responsibility (conscience) can be found. This suggests that emotional stability plays a mediator role within the existing linkage between feeling of family acceptance and prosocial behaviour in its altruism and anonymous conduct dimensions; responsibility (conscience) also plays a moderator role. To sum up, this research reflects family significance in the positive development of responsibility and emotional stability characteristics in children, these personality attributes being the variables with direct effect on prosocial behaviour of underaged offenders sentenced to a judicial measure of detention
