According to the strength model, self-control is a finite resource that determines capacity for effortful control over dominant responses and, once expended, leads to impaired self-control task performance, known as ego depletion. A meta-analysis of 83 studies tested the effect of ego depletion on task performance and related outcomes, alternative(More)
Public health practitioners and researchers in behavioral medicine recognize the need to find effective physical activity interventions and prescriptions to curb the growth in inactivity and prevent chronic For example, researchers in exercise physiology have focused on the minimal dose of exercise needed to gain favorable physiological adaptations to(More)
PURPOSE A meta-analysis of studies integrating the theory of planned behaviour (TPB) and self-determination theory (SDT) in health contexts is presented. The analysis aimed to provide cumulative empirical support for a motivational sequence in which self-determined motivation from SDT predicts the proximal predictors of intentions and behaviour from the(More)
The present study tested a motivational sequence in which global-level psychological need satisfaction from self-determination theory influenced intentions and behavior directly and indirectly through contextual-level motivation and situational-level decision-making constructs from the theory of planned behavior. Two samples of university students (N = 511)(More)

The current research tested the hypothesis that individuals engaged in long-term efforts to limit food intake (e.g., individuals with high eating restraint) would have reduced capacity to regulate eating when self-control resources are limited. In the current research, body mass index (BMI) was used as a proxy for eating restraint based on the assumption(More)
It is premature to regard the ego-depletion effect as " Too Incredible " The " strength " model conceptualizes self-control as a limited resource (Baumeister et al., 1998). Individuals are able to exert self-control, but only for a limited period after which capacity declines leading to reduced self-control capacity ; a state known as ego-depletion. The(More)
We examined a theoretical model of global self-esteem that incorporated constructs from achievement goal and self-determination theories. The model hypothesized that self-determined or autonomous motives would mediate the influence of achievement goal orientation on global self-esteem. The adapted version of the Behavioural Regulation in Exercise(More)
The present study examined the validity of an augmented version of Ajzen's (1991) theory of planned behaviour (TPB), adopting second-order latent factors to explain relationships between the differentiated components of the theory constructs. This model was tested on data from two independent samples, for exercise and dieting behaviours, respectively. The(More)
The distinction between intrinsic and extrinsic goals, and between goal pursuit for intrinsically and extrinsically motivated reasons, is a central premise of self-determination theory. Proponents of the theory have proposed that the pursuit of intrinsic goals and intrinsically motivated goal striving each predict adaptive psychological and behavioral(More)
