This study examined the utility of motivation as advanced by self-determination theory (Deci & Ryan, 2000) in predicting objectively assessed bouts of moderate-intensity exercise behavior. Participants provided data pertaining to their exercise motivation. One week later, participants wore a combined accelerometer and heart rate monitor (Actiheart; Cambridge Neurotechnology Ltd) and 24-hr energy expenditure was estimated for 7 days. After controlling for gender and a combined marker of BMI and waist circumference, results showed autonomous motivation to positively predict moderate-intensity exercise bouts of ≥10 min, ≥20 min, and an accumulation needed to meet public health recommendations for moderate-intensity activity (i.e., ACSM/AHA guidelines). The present findings add bouts of objectively assessed exercise behavior to the growing body of literature that documents the adaptive consequences of engaging in exercise for autonomous reasons. Implications for practice and future work are discussed.

Sport And Exercise

The present study investigated exercise behavior and its motives among Sultan Qaboos University students. Self-determination theory was used to investigate the relationship between these motives and the actual exercise behavior. The study sample consisted of 263 students from the Faculty of Education at Sultan Qaboos University (129 male and 134 female). The participants completed two questionnaires: an exercise behavior questionnaire which was developed specifically for this study; and an Arabic version of the Exercise Motivation Inventory (EMI-2), which was developed by Markland and Ingledew. Descriptive statistics showed that 20% of male students and 77% of female students didn’t participate at all in any sport and exercise activities; 45% of male students and 21% of female students participated moderately in sport and exercise activities (2-3 times a week); while 35% of the male students and 2% of the female students participated intensively in sport and exercise activities (almost on daily basis). Results indicated that intrinsic motives for exercise behavior (challenge, revitalization, health, affiliation and enjoyment) were common among the male participants. However, physically active females, extrinsic motivations (ill-health avoidance, positive health, revitalization, weight management, and appearance) were the major driving forces for their exercise behavior. Results of the current study provide support for the application of the self-determination theory within the Arab context.

Before And After

Abstract. This study tests two competing hypotheses, one based on the general aggression model (GAM), the other on the self-determination theory (SDT). GAM suggests that the crucial factor in video games leading to increased aggressiveness is their violent content; SDT contends that gaming is associated with aggression because of the frustration of basic psychological needs. We used a 2×2 between-subject experimental design with a sample of 128 undergraduates. We assigned each participant randomly to one experimental condition defined by a particular video game, using four mobile video games differing in the degree of violence and in the level of their frustration-invoking gameplay. Aggressiveness was measured using the implicit association test (IAT), administered before and after the playing of a video game. We found no evidence of an association between implicit aggressiveness and violent content or frustrating gameplay.

Abstract. Self-determination theory (SDT) suggests that the degree of autonomous behavior regulation is a characteristic of distinct motivation types which thus can be ordered on the so-called Autonomy-Control Continuum (ACC). The present study employs an item response theory (IRT) model under the ideal point response/unfolding paradigm in order to model the response process to SDT motivation items in theoretical accordance with the ACC. Using data from two independent student samples (measuring SDT motivation for the academic subjects of Mathematics and German as a native language), it was found that an unfolding model exhibited a relatively better fit compared to a dominance model. The item location parameters under the unfolding paradigm showed clusters of items representing the different regulation types on the ACC to be (almost perfectly) empirically separable, as suggested by SDT. Besides theoretical implications, perspectives for the application of ideal point response/unfolding models in the development of measures for non-cognitive constructs are addressed.
