High scores for the behaviour change taxonomy teams

Classificationsau

This week our undergraduate health psychology students have been looking at taxonomies of health behaviour change techniques – what they are, why we need them, and how to use them. A taxonomy (in the general sense) is a system for classifying things according to their distinguishing features.  Such classification systems have been used for everything from Catholic saints to Australian motion pictures.

To the health psychologist, a good taxonomy is a list which classifies the active ingredients that might form part of a behaviour change intervention. This might include, for example:

  • Providing people with information on the link between behaviour and health (e.g. telling people that smoking causes lung disease, that vaccination can protect from childhood illness, etc.)
  • Encouraging people to identify as a role model for others (e.g. encouraging parents to eat well and avoid smoking in order to set a good example for their children)
  • Giving people rewards contingent on their performing the desired behaviour (e.g. giving people a shopping voucher every time they pass a breath test that shows they’ve not smoked recently)

We need taxonomies to help us work out what the individual ingredients are in any programme or intervention. Knowing what the different parts are that make up the whole programme can help us test each part separately. Then we can focus on providing those active ingredients (programme components) that really work, and save money by leaving out components that don’t make any difference to the outcome.

There are lots of different lists and taxonomies available. For the undergraduate coursework we have chosen the taxonomy of 26 behaviour change techniques published by Abraham & Michie (2008). In today’s seminars we had a gentle competition to see which team (s) performed best at recognising the 26 techniques on the taxonomy. Scores were very impressive so this bodes well for students’ performance in the upcoming assignment.
