Testing a workplace physical activity intervention: a cluster randomized controlled trial.

Background: Increased physical activity levels benefit both an individuals' health and productivity at work. The purpose of the current study was to explore the impact and cost-effectiveness of a workplace physical activity intervention designed to increase physical activity levels.

Methods: A total of 1260 participants from 44 UK worksites (based within 5 organizations) were recruited to a cluster randomized controlled trial with worksites randomly allocated to an intervention or control condition.

Mediation of personality influences on physical activity within the theory of planned behaviour.

This study estimated the effect of extraversion, conscientiousness and variables from a modified two-component Theory of Planned Behaviour (TPB) on prospective self-reported physical activity (N = 397). Mediation analysis using structural equation modelling with bootstrapping suggested that only conscientiousness had significant effects on intention and behaviour. Affective attitude and perceived behavioural control partially mediated the effect on intention.

Classifying health-related behaviours: exploring similarities and differences amongst behaviours.

Objectives: The classification of health behaviours may provide a useful framework for understanding their characteristics and therefore the ways in which they are similar and different. However, to date, little research has attempted to identify these characteristics and explore the dimensions along which behaviours differ. This paper uses an inductive approach to explore this issue.
