Professor Marika Tiggemann is a leading academic at Flinders University specializing in body image, social media impacts, and eating disorder research. Her work examines how societal expectations and digital platforms like Instagram and TikTok influence body dissatisfaction, particularly among women and increasingly men. She has pioneered studies on 'fitspiration' trends, revealing their dual effects of motivating health behaviors while exacerbating negative self-comparisons. Her research spans over four decades, addressing cultural shifts in appearance ideals and advocating for systemic changes to improve body positivity.
Key areas of focus include:
- Media literacy interventions to counteract harmful beauty standards
- Evaluating food labeling strategies in campus environments
- Analyzing celebrity and social media influencers' effects on mental health
- Exploring maternal feeding practices and childhood food preferences
Her recent work emphasizes policy recommendations for regulating social media platforms and promoting healthier body image narratives. Notable contributions include longitudinal studies on adolescent social media use and experimental investigations into disclaimer labels for digitally altered images.
Research collaborations involve interdisciplinary teams addressing public health challenges through behavioral nudges, cognitive bias modification, and media literacy education.
