The role of explicit and implicit self-esteem in peer modeling of palatable food intake: A study on social media interaction among youngsters

Contains fulltext : 116712.pdf (publisher's version ) (Open Access)Objective: This experimental study investigated the impact of peers on palatable food intake of youngsters within a social media setting. To determine whether this effect was moderated by self-esteem, the present study examined the roles of global explicit self-esteem (ESE), body esteem (BE) and implicit self-esteem (ISE). Methods: Participants (N = 118; 38.1% boys; M age 11.14 +/-.79) were asked to play a computer game while they believed to interact online with a same-sex normal-weight remote confederate (i.e., instructed peer) who ate either nothing, a small or large amount of candy. Results: Participants modeled the candy intake of peers via a social media interaction, but this was qualified by their self-esteem. Participants with higher ISE adjusted their candy intake to that of a peer more closely than those with lower ISE when the confederate ate nothing compared to when eating a modest (beta = .26, p = .05) or considerable amount of candy (kcal) (beta = .32, p = .001). In contrast, participants with lower BE modeled peer intake more than those with higher BE when eating nothing compared to a considerable amount of candy (kcal) (beta = .21, p = .02); ESE did not moderate social modeling behavior. In addition, participants with higher discrepant or "damaged" self-esteem (i.e., high ISE and low ESE) modeled peer intake more when the peer ate nothing or a modest amount compared to a substantial amount of candy (kcal) (beta = -.24, p = .004; beta= -.26, p < .0001, respectively). Conclusion: Youngsters conform to the amount of palatable food eaten by peers through social media interaction. Those with lower body esteem or damaged self-esteem may be more at risk to peer influences on food intake.11 p

The effect of an intervention on schoolchildren's susceptibility to a peer's candy intake

Contains fulltext : 116715.pdf (publisher's version ) (Closed access)BACKGROUND/OBJECTIVES: The aim of the study was to pilot test two interventions designed to reduce children's susceptibility to peers' candy intake and to determine if interventions had different effects on boys and girls. SUBJECTS/METHODS: In the standard intervention, peer modeling was explained while communicating the importance of not following other's food intake by means of photos, video clips and interactive tasks. A second animated intervention was similar but added a monkey puppet as a (cue) reminder. A social modeling component was conducted 1 day after the intervention to test whether the interventions affected the extent to which children model their peers' eating. During the modeling session, the participants' (N = 141; 78% boys, mean age = 7.84+/-0.72 years) solved a puzzle with a same-sex 'confederate' who was instructed to eat chocolate candy when he/she was covertly signaled. The monkey puppet was put in sight to test whether the monkey served as a cue reminder in the animated intervention. Candy intake was compared across control and intervention conditions. RESULTS: The standard intervention reduced candy intake in boys but not girls. Nevertheless, children still remained susceptible to a peer's eating. There was no significant effect of the animated intervention on consumption. CONCLUSIONS: There are gender differences when children are exposed to an (over) eating peer. Although interventions are effective, social norms can be powerful. Social networks should be leveraged when possible. The study is registered at the Dutch Trial Register: NTR3459
