Using self-determination theory to explain sport persistence and dropout in adolescent athletes

Motivational characteristics are influential in shaping adolescents' desire to persist in sport or to discontinue their sport participation. Self-determination theory (Deci & Ryan, 2000) was utilized as the theoretical framework for this study. This theory examines whether sustained participatory involvement, defined as continued participation in the sport through the next year, was influenced by individuals' self-determined motivation and by the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness. Four hundred ninety two soccer players between the ages of 13 and 17 years comprised the sample. Results indicated sport dropout was explained by higher levels of amotivation, external regulation, and introjected regulation and by lower satisfaction of relatedness and autonomy needs. The findings of this study contribute to the knowledge base on sport dropout as they supported many of self-determination theory.     

Psychometric properties of the Psychosocial Risk Evaluation Battery for medium and small companies

The assessment of the presence and intensity of psychosocial risks is constant in research into Work Psychopathology. Many questionnaires and diagnosis systems are partial or else there is no standardization process or reliability and validity study. The main purpose of this work is to present the psychometric data of a multidimensional system to assess psychosocial risks, elaborated conjointly by the Universitat of Barcelona and the MC Mutual. This battery assesses companies, using information from the prevention technicians, the directive staff and the workers. With the diverse types of information, a triangulation proposal is established to offer a psychosocial risk profile linked to the evaluation needs.     

Analysis of effects of distribution of practice in learning and retention of a continuous and a discrete skill presented on a computer

This investigation examined the effects of distributed and massed practice on the learning and retention of a discrete computerized skill (Exp. 1) and a continuous computerized skill (Exp. 2). 40 men were randomly assigned to one of four groups, of which two groups took part in Exp. 1 and two groups in Exp. 2. Performance was assessed at various points during acquisition and then on 8 retention tests conducted at varying times after acquisition. Learning curves for practice were highly similar for the two conditions. Participants in the distributed-practice group performed significantly better than those in the massed-practice group at the end of practice on both the discrete and continuous skills. However, participants in the distributed-practice group performed significantly more poorly on retention during 24 hr. and after acquisition. Participants in the massed-practice condition performed significantly better on retention tests than did those who learned in the distributed-practice condition.     

The job involvement modulating role in the relationship between stress and job satisfaction

This paper analyzes the modulator role of job involvement in the relationship between stress and job satisfaction, using the OSI (Occupational Stress Indicator) model. For this purpose, we analyzed: six sources of stress, the OSI job satisfaction results, and a job involvement scale. The sample consisted of 779 professional soldiers from the Spanish Army. The results show that when the levels of the two dimensions job involvement (psychological identification and job-related feelings of duty-obligation are high, stress due to achievements and career development and social relationships will have no influence on job satisfaction. However, we found higher job satisfaction, even when stress is high, in those situations where psychological identification is low and job-related feelings of duty-obligation are high.     

Youth sport dropout from the achievement goal theory

This study examined dropout behavior, using the conceptual framework of achievement goal theory. We hypothesized that dropout could be predicted by a high ego-oriented goal disposition in combination with a low perception of personal skill and the perception that the coach and sport peers maintained ego-oriented sport success criteria. The participants were 134 adolescent athletes involved in high-level competitive sports participation. The results of structural equation modeling (SEM) supported these hypotheses. Furthermore, the variables that directly predicted sport dropout were the participant's ego orientation (positively) and perception of skill (negatively). These findings and the research prospects are discussed.     

The consequences of a nurse's negative evaluation of a blood pressure reading. Implications for the etiology of white-coat hypertension

The aim of this study was to show how a nurses negative evaluation of a blood pressure (BP) reading can cause an increase in BP in the following reading. Twenty-five subjects with normal pressure who had been informed that they were to participate in an epidemiological BP study took part and they were divided into two groups. After taking the first BP reading, participants from the experimental group were informed that their pressure was normal but high for their age, whereas those in the control group were told that their pressure was normal for their age. The results showed that this comment caused a significant increase in the diastolic BP of the experimental group. The theoretical and clinical implications of this reaction are discussed in relation to the phenomenon known as White-Coat Hypertension from the perspective of the theory of incubation.     

Job demands, job resources and individual innovation at work: going beyond Karasek's model?

The job demands-control model is one of the most recognized models in occupational stress research. It has, however, provided contradictory results, and the active learning hypothesis derived from this model has been under-researched in comparison with research on the stress hypothesis. The main aim of this study is to test the Job Demands Resources Model in the prediction of individual innovation at work as an active coping strategy. Results with hierarchical multiple regression analyses provide empirical support for this model. We found a positive relationship between job demands and individual innovation in situations characterized by high job resources. Finally, we discuss the limitations and practical implications of this study.     

Effect of manipulating positive and negative feedback on goal orientations, perceived motivational climate, satisfaction, task choice, perception of ability, and attitude toward physical education lessons

This study examined the effect of different types of feedback on goal orientation, perception of motivational climate, satisfaction, and boredom in physical education (PE) classes, pupils' preferences for challenging versus easy tasks, pupils' attitudes towards PE lessons, and perception of gymnastic ability. 95 subjects in three treatment conditions (positive feedback, negative feedback, and both feedback types) participated in 14 lessons and completed pre- and postintervention measures. Results showed that subjects in the positive feedback group had significantly higher scores on learning-oriented motivational climate and enjoyment than the subjects of the negative feedback group. The negative feedback group reported higher scores on performance-oriented motivational climate than the positive feedback group. Results also showed that subjects in the group receiving both types of feedback had lower scores on learning-oriented motivational climate, higher scores on enjoyment than the negative feedback group, and lower scores on boredom than the positive feedback group. The effects of feedback on physical education students' motivation are discussed.     

Expert-novice differences in cognitive and execution skills during tennis competition

This study deals with decision and execution behavior of tennis players during competition. The study is based on the expert-novice paradigm and aims to identify differences between both groups in the decision-making and execution variables in serve and shot actions in tennis. Six expert players (elite Spanish tennis players) and six novice players (grade school tennis players) took part in this study. To carry out this study, the observation protocol defined by McPherson and Thomas in 1989, in which control, decision-making and execution variables were included, was used, where it was applied to the performance of the tennis player in a real match situation. In the analysis, significant differences between experts and novices in decision-making and execution variables are found wherein it can be observed that experts display a greater ability to make the appropriate decisions, selecting the most tactical responses to put pressure on the opponent. Expert tennis players were also able to carry out forceful executions to their opponent with greater efficiency, making the opponent's response to a large extent more difficult. These findings are in accordance with those of McPherson and colleagues.     

Beyond perception: Testing for implicit conceptual traces in high-load tasks

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. (2009). Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.
