The Relationship

Background: Despite several benefits, research has found that problematic smartphone use is positively associated with behavioral problems. However, the internal mechanisms underlying this relationship need further investigation. So, the current study aimed to investigate the mediating role of sleep disturbance in the relationship between problematic smartphone use and aggression. Methods: The research design was descriptive-correlational. Also, the study population included the male university students of the Islamic Azad University of South Tehran Branch in the academic year of 2019-2020. Using the convenience sampling method, a total number of 213 participants from two faculties (Faculty of Human Sciences and Faculty of Law and Political Sciences) were selected and tested by Buss-Perry Aggression Questionnaire, Smartphone Addiction Scale-Short Version, and Pittsburgh Sleep Quality Index. Then, the Pearson correlation and path analysis were conducted to analyze the data. Results: The results revealed the significant and direct effects of problematic smartphone use on aggression (β=0.12, P<0.05), sleep quality on aggression (β=0.37, P<0.001), and problematic smartphone use on sleep disturbance (β=0.42, P<0.001). Also, sleep quality significantly mediated in the relationship between problematic smartphone use and aggression (β=0.15, P<0.01). Conclusion: According to the present findings, problematic smartphone use and sleep disturbance are two important factors affecting aggressive behavior among university students. These findings highlight the critical role of early intervention for aggression with a focus on those with problematic smartphone use and more specifically those with sleep disturbance.

Hedonic Benefits

We examined consumers' perceptions of, and responses to, variety in product bundles in 3 studies with Chinese university students aged between 17 and 29 years. In Study 1 (117 participants) we found that variety (vs. nonvariety) bundles were more attractive and more likely to be purchased, and this effect was robust across different variety formats. In Study 2 (89 participants) the mediating role of perceived hedonic benefits was supported, that is, participants responded to the level of variety in product bundles as they tried to maximize their hedonic benefit from the consumption. In Study 3 (74 participants) we further explored the moderating role of consumption goal and found that participants were willing to forgo an additional quantity to have variety, especially when their consumption goal was hedonic rather than utilitarian. Theoretical implications and practical implications for marketers are discussed.
