Research Framework

To guide the research activities of SPARColl we are using the conceptual framework outlined by Campbell et al., 2000. The framework identifies a series of stages for research and knowledge development. Progression through the stages need not be linear but each stage should be informed by prior stages. Our long term goal of SPARColl will be to reach stages four and five in this model in relation to walking and physical activity levels. Our current three year goal is to provide good information for stages one, two and three.

Stage One

Theory and model development: relevant theory from multiple disciplines are explored and hypotheses generated (for example which theories (behavioural, health, economic, environmental) are most appropriate for promoting increasing walking?)

Stage Two

A modelling stage in which the 'active ingredients' of an intervention are identified. For example, what helps people change their walking behaviour?

Stage Three

An exploratory stage in which some aspects of the possible interventions are tested and explored to determine how feasible they might be. For example, will GPs distribute pedometers and will people use them to increase walking levels. This stage could also investigate the relationship between the environment and physical activity.

Stage Four

A definitive trial stage in which a randomised controlled trial, designed with the knowledge that has been accumulated from earlier stages and with appropriate statistical power, is undertaken. This stage could be used for example, to implement a community based trial of whether or not pedometers can increase walking behaviour.

Stage Five

A stage of implementation in which it is determined whether the findings of the trial can be disseminated and used elsewhere.
