People with learning disabilities are increasingly living in community settings with support from care staff who have a large influence on their lives, including diet. The Theory of Planned Behaviour (TPB) is a model that has been used to examine many health behaviours with reference to underlying beliefs. This model has only recently been applied to proxy populations, i.e. with one group about the health behaviours of another. The purpose of the current project was to determine if the TPB was a useful predictor of care staff’s intentions to encourage a healthy diet in their clients with a learning disability. Method: 112 care staff from five voluntary or charitable organisations that provide support to people with learning disabilities were involved in the study and care staff from each completed a TPB questionnaire regarding their intention to encourage healthy eating over the next year for their clients. Results: The results indicate that the Theory of Planned Behaviour is indeed applicable to this population. The variables which make up the original model of Theory of Planned Behaviour: attitudes, subjective norm and perceived behavioural control, were found to be statistically significant predictors of carers’ intentions to encourage healthy diet in their client. Additional variables (self-efficacy and self identity) were not found to improve the model. Subjective norm was found to be the most predictive variable within the model. The results are discussed with a view to how Theory of Planned Behaviour could be a useful model in guiding healthy eating interventions within this population.
