Interpersonal behaviors in sports context: Spanish adaptation and measurement invariance.

Introduction: The interpersonal behavior questionnaire (IBQ) is an instrument that measures support and thwarting interpersonal behaviors based on the self-determination theory (SDT). The aim of this work was to adapt the IBQ to the Spanish spoken in Mexico and to examine its psychometric properties (structural validity, discriminant validity, composite reliability, factorial invariance, and nomological validity) in a sample of athletes.

Methods: For this purpose, 472 athletes (average age 17.

Adaptive Social Factors and Precompetitive Anxiety in Elite Sport.

Grounded in achievement goal theory and self-determination theory, the aim of this study was to analyze the motivational determinants of precompetitive anxiety in the sports context, considering the horizontal motivational sequence: adaptive social factors (task-involving climate, autonomy support style), competence need, types of motivation (autonomous motivation, controlled motivation, amotivation), and consequences (precompetitive anxiety and self-confidence). This study was also conducted in order to analyze the mediating role of the need for competition and motivational regulations on social factors and consequences. The sample consisted of 217 athletes of both sexes engaged in elite sport, who answered a series of questionnaires to measure study variables to develop an analysis of the structural equation model.

Mexican Validation of the Engagement and Disaffection in Physical Education Scale.

To date, no instrument adapted and validated that measures engagement and disaffection in the physical education class has been found, which limits the generation of knowledge of this area in Mexico. The aims of this study were to translate and adapt the engagement and disaffection scale to the context of physical education in Mexico and to examine its reliability, structure (two and four factors), and factorial invariance by gender in Mexican fifth- and sixth-grade elementary school students. A total of 1470 students participated (50.

Psychometric Properties of a Spanish Version of the Basic Needs Satisfaction in Sports Scale.

The Basic Needs Satisfaction in Sport Scale (BNSSS) is an instrument designed to measure the level of satisfaction of the three basic psychological needs (BPN) in sports, according to The Self-Determination Theory (SDT). The purpose of this research was to adapt BNSSS to Mexican Spanish and analyze its psychometric properties (factorial validity, factorial invariance, internal consistency, convergent validity, and nomological validity). Thus, 542 athletes (average age: 12.
