Examining the relationship between academic stress and motivation toward physical education within a semester: A two-wave study with Chinese secondary school students.

The present study aimed to investigate the relationship between academic stress and motivation toward physical education (PE) through a longitudinal design with cross-lagged panel analyses. A sample of 556 Chinese secondary school students participated in the research and completed Perceived Locus of Causality Scale and Educational Stress Scale for Adolescents at the beginning of the semester and 3 months later. The results demonstrated that academic stress factors were positively related to less self-determined motivations except that worry about grades was positively related to more self-determined motivations within each time point.

Can Multi-Item Measures and Single-Item Measures be Trusted to Assess Self-Determination Theory Constructs in the Elderly?

Background: Measuring complex constructs, such as those from self-determination theory models, is challenging in the elderly due to the response process, particularly in collective data gathering. In order to examine this construct in physical activity settings we aimed at determining whether single-item measures were as good as pre-existing multi-item measures. For that reason, we developed seven single-item measures targeting perceived interpersonal styles, basic needs satisfaction, and well-being.

Initial psychometric testing of the coach-adapted version of the empowering and disempowering motivational climate questionnaire: A Bayesian approach.

The present study examined the psychometric properties of the coach-adapted version of the Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ) using Bayesian structural equation modelling (BSEM). The sample included 780 ( = 36.4; = 10.

The Effect of Coaches' Controlling Style on the Competitive Anxiety of Young Athletes.

Framed on a Self-Determination Theory perspective, the purpose of this study was to explore the predictive capacity of coaches' interpersonal controlling style on the competitive anxiety of young athletes, considering the mediating effect of the athletes' controlled motivation on this relationship. The sample consisted of 1166 athletes, aged between 9 and 18, who ranked their perceptions of coaches' controlling style, as well as the reasons for participating in sport and their competitive anxiety before or during competition. The structural models assessing both the direct effect of the controlling style on the anxiety and the complete mediated effect of the controlled motivation on this relationship revealed good fit indices.

Acceptance of gamesmanship and cheating in young competitive athletes in relation to the motivational climate generated by parents and coaches.

The goal was to assess the relation between the acceptance of using gamesmanship and cheating in sports and the type of motivational climate created by coaches and parents. The sample consisted of 110 soccer, basketball, and handball players from the Balearic Islands competition (70 boys, 40 girls; M age = 14.7 yr.

[Psychometric quality supporting the Spanish adaptation of the Behavioral Regulation in Sport Questionnaire].

The goal of this study is to present the Spanish adaptation of the Behavioral Regulation in Sport Questionnaire made up of 24 items that measure the 6 behavioral regulation factors expected by the self-determination theory developed by Deci and Ryan. Supporting evidence of conceptual equivalence and quality of the cultural and linguistic adaptation derive from the conciliation of different terms (experts and target population). Cognitive interviews and the fact that 94% of respondents provided complete answers and without aberrant response patterns support the feasibility of the questionnaire.

[Adaptation and validation of the Spanish version of the Sport Anxiety Scale SAS-2 for young athletes].

The aim of this study is to design a Spanish version of the Sport Anxiety Scale (SAS-2). The questionnaire, originally developed by the Washington University research group in sport psychology to evaluate anxiety in young athletes, was translated and adapted following the APA protocol and its psychometric properties were assessed through internal consistency analysis, confirmatory factor analysis and validity evidence. The Spanish version of the Sport Anxiety Scale has revealed good internal consistency indexes in each subscale and its factor structure has faithfully replicated the one obtained in the original measure.

Commitment, enjoyment and motivation in young soccer competitive players.

Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season.

The effect of achievement goals on moral attitudes in young athletes.

The purpose of the study is to assess the hypothesis that achievement goal orientations will predict sportpersonship attitudes among young athletes, namely that task orientation will predict socially positive attitudes and ego orientation will predict socially negative attitudes. For hundred and eighty two athletes, aged 13 to 16 years completed the Portuguese versions of the Task and Ego Orientation in Sport Questionnaire (TEOSQp) and of the Sports Attitudes Questionnaire (SAQp). Bivariate correlations were used to examine the relationships between TEOSQp and SAQp.

[Motivational climate and coaches' communication style predict young soccer players' commitment].

The purpose of this research was to study the role of coaches' communication style and coach-created motivational climate in young soccer players' enjoyment and commitment. Four hundred and fifteen young soccer players of high competitive level in the age range from 14 to 16 completed the following questionnaires: a) coach-induced perceived motivational climate (PMCSQ-2), b) coaches' behaviour perception (CBAS-PBS), and c) sport commitment (SCQ). Results showed that coach-created motivational climate correlated highly with the perception of coaches' communication style.

The commitment of young soccer players.

The main purpose of this study was to test the Sport Commitment Model in young soccer players. Participants' ( N = 437) age ranged from 14 to 16 years. Based on the sport commitment model proposed by Scanlan and colleagues, 6 scales and 28-items constitute the Sport Commitment Questionnaire (SCQ).
