An exploratory experimental study examining the short-term effects of a public service announcement on parents' perceptions of the descriptive norm for children's outdoor play: A cautionary tale.

Abstract

Public service announcements (PSA) targeting physical activity are not always effective at enacting behaviour change. One factor that may impact message effectiveness is whether the message matches its intent (ie, what norm is being portrayed and received). The current study explored the effects of two PSAs on parents' perceptions of outdoor play. Parents (N=333) completed a pre/postexperimental online survey to examine the acute impact of a PSA on their perception of how often children play outdoors (ie, descriptive norms). Participants provided their descriptive norm perceptions and then were randomised to view one of two PSAs: (a) the Mr. Lonely PSA, which portrayed outdoor activity as not normative, and (b) a control message, which portrayed outdoor activity as the norm (VERB PSA). After viewing their PSA, descriptive norm perceptions were reported again. A two-way mixed ANOVA indicated that participants who viewed the Mr.Lonely PSA (where outdoor play was not normative) perceived that children and youth played outdoors less frequently immediately after watching the PSA compared to before viewing it (P<0.05). No significant change occurred in the control condition. PSAs can alter individuals' perceptions of whether they perceive outdoor play as normative among children and youth. SO WHAT?: As individuals align their behaviour with what is typical, PSA developers should be wary of what message is being conveyed. In terms of activity, portraying that outdoor play is not normative may not have the intended outcome.
