“…In a cross-sectional survey of 4,600 Dutch 15-to 25-year-olds, Hald, Kuyper, Adam, and de Wit (2013) reported that more than 88% of male and 44% of female participants had used SEM in the past 12 months. Comparable findings were reported in a population-based Swedish study, in which 95% of the surveyed male 16-year-olds used SEM (Mattebo, Tyden, Haggstrom-Nordin, & Nilsson, 2013). In an earlier study, the 2010 retrospective assessment of early SEM use in a national probability based sample of Croatian emerging adults, a substantial minority (40% of female and 39% of male participants) reported exposure to SEM before the age of 15 (Sinković, Štulhofer, & Božić, 2013).…”
