Along with my colleagues Juliet Wakefield, and Fabio Sani, I have recently had a paper published in the British Journal of Developmental Psychology. Our paper, entitled ‘Greater Number of Group Identifications is Associated with Healthier Behaviour in Adolescents’, investigated the relationship between group identification (with the family, school, and friendship groups) and adolescent health behaviour (smoking, binge drinking, and cannabis use).
We found that identification with the family and school groups predicted reduced odds of substance use, whereas identification with the friend group predicted increased odds of substance use. Furthermore, the greater the number of social groups with which the participant strongly identified, the lower the odds that he/she participated in negative health behaviours. In contrast, merely having contact (rather than identifying strongly) with these groups increased the odds of participation in these behaviours.
We took our findings to suggest that group identification influences behaviour to the extent that it encourages adherence to group norms.
