Question 1

How eating-related social media postings influence healthy eating in senders and network members: Two field experiments with intensive longitudinal data
Kilb et al., 2023

Answer 1

• 2 longitudinal field experiments
  
  • Self reports and social media data
  • Posting behaviour of young adults was manipulated
  • posting led to a stronger increase of senders’ and network members’ intake, but this increase was not statistically significant.
  • Posting led to higher perceived social support and injunctive norms of senders
  • Posting supported EB change; the effect size was comparable to picture-based self-monitoring of intake .
  • Intraindividual variations in senders’ daily eating-related social media activities were associated with daily eating behavior and perceived social support, daily self-efficacy, experiential and instrumental attitudes, and goal commitment.
  • social media environments should be considered in research and interventions targeting eating behavior of young adults.
