Measuring adolescents' use of social media: A systematic review

Objective. - The purpose of this review was to provide an overview of the methods used to measure social network site use among adolescents. Such a review is important given the number and diversity of sites and the prevalence of their use among adolescents. Methods. - A systematic review of the literature was conducted in line with PRISMA guidelines to arrive at an analysis of 58 peer-reviewed studies indexed in PubMed, PsychInfo, or Scopus. To be included in the review, articles had to be peer-reviewed, available in full text, and published in French or English. For inclusion, studies were required to pertain to adolescents aged between 11 and 18 years; to focus on social network site use and indicate how their use was estimated. Studies that simultaneously examined social network sites and general internet use or video games and only provided a combined analysis were excluded. The keywords for the search were: social media use, social media usage, social media misuse, measure, teen, and adolescents. Results. - In the literature, different methods were used to operationalize the use of social network sites: quantitative methods with the measurement of frequency and duration of use of social network sites, and qualitative methods to measure the different activities adolescents engage in on such sites. In this review, 28 articles investigated the use of social media through a measurement of frequency and 22 articles through a measurement of the duration of use. Most of the studies focused on social network sites in general, without specifying which sites in particular were considered by the respondents when answering the question. However, some articles provided cross measures of quantitative and qualitative measurements resulting in the examination of both the frequency of use and the time spent on specific activities on social network sites. Conclusions. - The present review highlights the great diversity in the methods used to measure the use of social network sites among adolescents. The reliance on frequency-based measurements without taking into account the specificities of the activities or sites involved limits the investigation of their impact on adolescent functioning and behaviors. Given the observed discrepancies in the literature concerning the measurement of social network site use among adolescents and their associated biases, the development of specific instruments is needed to advance in this important field of research.
