Dr Inge Kersbergen
Inge Kersbergen is a post-doctoral researcher at the department of Psychological Sciences at the University of Liverpool. She is interested in social and environmental influences on health behaviour. Inge holds a master’s degree in behavioural science from the Radboud University, Nijmegen, and a PhD in Psychology from the University of Liverpool. During her post-doc, she examined how serving size reductions can be used to decrease alcohol consumption. She will develop this line of work further as an SSA academic fellow at the University of Sheffield, where she will investigate whether systematic serving size reductions may reduce off-trade alcohol consumption.

Reducing the standard serving size of alcoholic drinks in pubs and bars may reduce alcohol consumption, but it is unclear how these findings would generalise to drinking in the home. Alcohol is served differently at home than in licensed premises, which is likely to influence the effectiveness of serving size interventions. In particular, alcohol served by the glass in the on-trade implies that the serving provided constitutes a single drink, but the number of individual servings in shop-bought, packaged alcohol is ambiguous, and alcohol consumers may perceive a wide range of container sizes as containing a single serving. Therefore, it is possible that serving size interventions in shops would only influence consumption when reducing the size of packaging that contains a single serving, but not when reducing the size of packaging that contains multiple servings (e.g., large bottles of wine or spirits). In this talk, I will discuss my ongoing research that investigates how the packaging size of shop-bought alcohol is associated with alcohol consumption and which range of packaging sizes is the optimum target for size interventions.
