“…By virtue of its widespread use, relative anonymity, cost-effectiveness and acceptability, FB is increasingly being used as a strategy of recruitment for research (e.g., Batterham, 2014 , Berry and Bass, 2012 , Eysenbach et al, 2012 , Harris et al, 2015 , Koenings et al, 2015 , Nelson et al, 2014 , Wen-Cheng et al, 2011 , Young et al, 2014 ) replacing traditional recruitment strategies ( Harris et al, 2014 , van Voorst et al, 2015 ). More recently, FB has also been successfully used to facilitate recruitment of populations who might not respond to traditional recruitment strategies, including adolescents ( Amon et al, 2014 , Amon et al, 2015 ), young adults aged 18–23 ( Loxton et al, 2015 ) and ethnic minorities ( Ünlü Ince et al, 2014 ).…”
