Interpersonal Perfectionism and Perceived Control's Influence on the Continuity of Sports Practice in Adolescents.

Based on the theory of planned behavior, the objective was to test a theoretical model that explains the intention to continue practicing sports among adolescents currently involved in sports practice in Mexicali based on factors that generate perceived social pressure to be perfect (perceived descriptive norm) and that lead to internal factors of perceived control (perceived competence, general self-concept, and enjoyment). A battery of questionnaires that measured the study variables was applied to 195 adolescent athletes of both sexes. The causal model with observed variables rejected part of the hypothesis since the athletes' perception that their parents impose high performance expectations on them and that they criticize them when these expectations are not achieved was not associated with the athletes' perceived competence.

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.

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.

Situational and Dispositional Factors that Predict Motivation: a Multilevel Study.

This study aimed to test a multilevel mediation model which examined the relationship between the perceived motivational climate created by coaches at team level and motivational regulations towards sport at individual level, as mediated by individual goal orientations. 211 university athletes from 20 teams training in different types of sport completed a battery of instruments that measured the variables included in the model. The statistics significance level was .
