The influence of group identification on the adoption of peer group smoking norms

According to self-categorisation theory, referent informational influence is a process whereby individuals conform to the norms of social groups with which they identify. This paper investigates whether smoking is a stereotypical attribute of particular social groups and how the group normative influence with regard to smoking may affect group members' personal smoking involvement. A sample of young adults (initial W = 3300) was surveyed at 3 six-month intervals after leaving their final year of school. Results showed that particular labels (such as rebels, using illegal drugs and riding motor bikes) were associated with extensive smoking widiin peer groups. An individual's smoking status was found to be strongly related to a favourable smoking norm in the peer group. This relationship was found to be stronger amongst those who strongly identified with their peer group compared with those who were weakly identified. Individuals whose behaviour was discordant with the group norm tended to express weak identification with the group and, over time, to alter their main friendship group to one with norms that are more compatible with their own behaviour
