“…This study performed with 839 students shares similar features with the research carried out by Morente-Sánchez, Mateo-March & Zabala 2013, Yager & O'Dea (2014) and Morente-Sánchez & Zabala (2015). Just like in other studies that predate ours (Backhouse et al, 2013;Chan et al, 2015;Ruiz-Rico, Cachón, Valdivia & Zagalaz, 2014;Whitaker, Backhouse & Long, 2014), we found that attitudes are extremely important when taking the decision to use performance-enhancing drugs.…”
