![]() In this research, we leverage a very natural aspect of social settings, namely that consumers are usually part of multiple-as opposed to single-networks. With data on a sample of individuals from a network, these effects are not identified. However, the two effects are not separately identified in general in the standard linear-in-means model unless data on all members of an individual’s network are available. These models can be used to examine whether social influence is truly a result of agents affecting each other through their choices simultaneously (endogenous effect) or of having similar taste and characteristics (homophily). ![]() Among the many different empirical models applied for such investigations, the most common class of model is the linear-in-means model. There has been a considerable amount of interest in the empirical investigation of social influence in the marketing and economics literature in the last decade or so. Given the importance of attachment to parents and peers in adolescent health and development, concern about high levels of screen time among adolescents is warranted. Screen time was associated with poor attachment to parents and peers in 2 cohorts of adolescents 16 years apart. Among the DMHDS cohort, more time spent television viewing was associated with low attachment to peers. Among the YLS cohort, more time spent playing on a computer was also associated with low attachment to parents. More time spent television viewing and less time spent reading and doing homework were associated with low attachment to parents for both cohorts. ![]() Screen time and low attachment to parents and peers as measured by the Inventory of Parent and Peer Attachment. ![]() The YLS cohort (n = 3043) was aged 14 to 15 years in 2004. The DMHDS cohort (n = 976) was aged 15 years in 1987-1988. Members of the DMHDS cohort were interviewed as part of a full day of assessment, and members of the YLS cohort completed a self-report questionnaire in a supervised classroom setting. To examine associations between screen time (television, video or DVD, gaming, and computer use) and attachment to parents and peers in 2 cohorts of adolescents 16 years apart.Ĭross-sectional data regarding screen time and attachment to parents and peers were collected for 2 cohorts of adolescents, one in 1987-1988 (the Dunedin Multidisciplinary Health and Development Study cohort) and the other in 2004 (the Youth Lifestyle Study cohort). ![]()
