“…Previous research has identified numerous factors related to helmet use among adolescents, including past helmet use behavior (Quine, Rutter, & Arnold, 1998;Seijts, Kok, Bouter, & Klip, 1995), role modeling, parental encouragement, (Cryer et al, 1998;Lajunen & Rasanen, 2001), attitudes (Berg & Westerling, 2001;Cryer et al, 1998;Rodgers, 2000), and having friends who use helmets (Cryer et al, 1998;Lajunen & Rasanen, 2001). Furthermore, safety considerations (Berg & Westerling, 2001;Finch, 1996), compulsory helmet wearing by law (Sutton, 1994), and educational campaigns (Ashby, Routley, & Stathakis, 1998;Brewer et al, 1995) have been associated with increased use of helmets.…”
