Ego depletion and the strength model of self-control: a meta-analysis.
TLDR
Support for motivation and fatigue as alternative explanations for ego depletion indicate a need to integrate the strength model with other theories and provide preliminary support for the ego-depletion effect and strength model hypotheses. Expand
A Meta-Analytic Review of the Common-Sense Model of Illness Representations
A meta-analysis of empirical studies ( N = 45) adopting Leventhal, Meyer and Nerenz's (1980) Common Sense Model (CSM) of illness representations is presented. The average corrected intercorrelationExpand
A Meta-Analytic Review of the Theories of Reasoned Action and Planned Behavior in Physical Activity: Predictive Validity and the Contribution of Additional Variables
The aim of the present study was to examine relations between behavior, intentions, attitudes, subjective norms, perceived behavioral control, self-efficacy, and past behavior across studies usingExpand
A Multilab Preregistered Replication of the Ego-Depletion Effect
TLDR
The size of the ego-depletion effect was small with 95% confidence intervals (CIs) that encompassed zero (d = 0.04, 95% CI [−0.07, 0.15]), and implications of the findings for the psyche depletion effect and the resource depletion model of self-control are discussed. Expand
Effects of an intervention based on self-determination theory on self-reported leisure-time physical activity participation
TLDR
It is concluded that self-determination theory provides a useful framework for the development of school-based interventions that ultimately affect leisure-time physical activity participation. Expand

The Processes by Which Perceived Autonomy Support in Physical Education Promotes Leisure-Time Physical Activity Intentions and Behavior: A Trans-Contextual Model
The trans-contextual model proposes that young people's perceived autonomy support in physical education will affect their perceived locus of causality, intentions, and physical activity behavior inExpand
Integrating the theory of planned behaviour and self-determination theory in health behaviour: a meta-analysis.
TLDR
A meta-analysis of studies integrating the theory of planned behaviour and self-determination theory in health contexts provided cumulative empirical support for a motivational sequence in which self-determined motivation from SDT predicts the proximal predictors of intentions and behaviour from the TPB. Expand
Teacher, peer and parent autonomy support in physical education and leisure-time physical activity: A trans-contextual model of motivation in four nations
TLDR
An extended trans-contextual model of motivation for health-related physical activity was tested in samples from four nations, which provides an explanation of the processes by which perceived autonomy support from different sources affects health- related physical activity motivation across these contexts. Expand
Implementation intention and action planning interventions in health contexts: state of the research and proposals for the way forward.
TLDR
Evidence supports the effectiveness of planning interventions in health behaviour with advantages including low cost and response burden, but there is considerable heterogeneity in the effects across studies and relatively few registered randomised trials that include objective behavioural measures.
