Abstract
Many people would like to reduce their smartphone or social media usage in the hope of improving productivity and well-being but fail to do so due to the habitual nature of smartphone and social media use. Understanding how to encourage consumers to change this habit is important for policy makers. We investigate strategies to manage this consumption with a meta-analysis examining what types of strategy work best. We also address the critical question of consumer heterogeneity, i.e., whether certain people benefit from interventions than others. This study aspires to guide future research of digital addiction interventions, and provide actionable recommendations for policymakers, advocacy groups, and consumers to initiate cost-effective and lasting behavioural change in the domain of smartphone and social media use.
About presenter
Dr. Pham Quang Duc is assistant professor at CUNEF Universidad (Madrid, Spain). He obtained his PhD in Business Studies from IE Business School. His research primarily focuses on consumption habit formation, consumer’s heuristics, and how to apply empirical findings to consumer behavior, especially in the contexts of moderate, sustainable consumption, and interaction between humans and technology. His most recent research used field experiments to explore how to help people reduce social media and mobile phone over-usage. He has presented his works at several international conferences such as Association of Consumer Research, European Marketing Academy, American Marketing Association, and Subjective Probability, Utility, and Decision Making.
