Understanding behaviour across time and context: The example of Weight Loss Maintenance

There is a growing body of evidence for the effectiveness of interventions to modify health related behaviour such as physical activity and diet and related outcomes such as overweight/obesity. However, effect sizes remain modest, responses to interventions are variable and sustainability of effects remain limited. Focusing on the example of weight loss maintenance, we will focus on three challenges for behavioural science: 
  1. Variability of behaviour and its determinants across time and context. The development of quantitative n-of-1 methods in health psychology allow to model trends, predictors and responses to interventions within individuals based on high resolution individual data. Rather than applying between-subject level evidence, behavioural outcomes can be modelled within individuals to gain insights into the temporal/contextual structure of intra-individual variability in outcomes and modifiable correlates allowing for personalised intervention tailoring. Examples from physical activity and weight management research will be presented.
  2. Multiple Goal Pursuit. Traditional psychological approaches often focus on a single goal or outcome at the time. Understanding features of individual goal systems, e.g., goal facilitation, goal conflict and prioritisation, allows for a novel theoretical way of understanding behaviour and identifies new hypotheses for behavioural research and an evidence base is currently emerging.
  3. Maintenance of Behaviour Change. The overwhelming challenge of behaviour change is maintaining initial changes. Taking the example of weight loss, 250 million adults in the European Union will make a weight loss attempt every year and there is now a good understanding what makes interventions effective. However, most individuals will regain weight. The state of the current evidence and emerging theorising on maintenance will be reviewed and the application of this science to patient care is illustrated based on the example of behavioural diabetes remission
