Social media platforms emerged with the promise to increase social connections and conversation, both of which are presumably conducive to mental health and happiness. However, early research appeared to suggest that social media use, particularly for adolescents, may have the opposite effect, with studies showing negative effects of social media use on well-being, prompting calls for greater scrutiny and regulation of social media platforms. In contrast, the more recent large-scale meta-analytic and longitudinal studies suggest that the effects may be minimal to the point of being inconsequential. In this research, we review the latest findings on the effects of social media use on adolescent psychological well-being, with the aim of making sense of these conflicting findings. In doing so, we discuss methodological issues that hamper the interpretation and generalizability of previous findings and provide a research agenda for consumer researchers interested in studying the effects of adolescent social media use.

A brand name's linguistic characteristics convey brand qualities independent of the name's denotative meaning. For instance, name length, sounds, and stress can signal masculine or feminine associations. This research examines the effects of such gender associations on three important brand outcomes: attitudes, choice, and performance. Across six studies, using both observational analyses of real brands and experimental manipulations of invented brands, the authors show that linguistically feminine names increase perceived warmth, which improves brand outcomes. Feminine brand names enhance attitudes and choice share—both hypothetically and consequentially—and are associated with better brand performance. The authors establish boundary conditions, showing that the feminine brand name advantage is attenuated when the typical user is male and when products are utilitarian. [ABSTRACT FROM AUTHOR]

As global material wealth rises and young people are heavily exposed to advertising across a range of channels, including rapidly developing social media where material goods are flaunted as symbols of a happy and successful lifestyle, materialism levels across the world seem likely to rise. Given consistent research showing the correlation between materialism and low well-being, this gives cause for concern. However, no studies have so far tested whether current measures of youth materialism are generalizable across different countries and cultures. Our article fills this gap by exploring through a range of internal and external validity tests whether the popular Youth Materialism Scale (YMS) can be used with confidence across China, France, Belgium, Poland, the United Kingdom, and the United States. We show that a 5-item version of YMS is invariant across the countries (internal validity) and that it broadly correlates in expected ways with six different theoretically related constructs: Self-Esteem, Life Satisfaction, Attitude to Advertising, Parental Support, TV Use, and Internet Use (external validity). We believe that researchers and policy makers can confidently use this 5-item version of the scale in international contexts. [ABSTRACT FROM AUTHOR]
