This study examined differences in minor hockey athletes' experiences according to the year their league implemented the Respect in Sport Parent Program (RiSPP). Athletes (N = 68) completed online measures of spectators' behaviours (Omli & LaVoi, 2009), prosocial and antisocial behaviours (Kavussanu & Boardley, 2009), and parental support and pressure (Anderson et al., 2003). One way ANOVAs revealed significant differences in athletes' perceptions of parental support (F (2, 60) = 3.34, p < .05, ?2 = .07), prosocial behaviours towards teammates (F (2, 61) = 4.60, p < .05, ?2 = .10), and antisocial behaviours towards opponents (F (2, 61) = 3.88, p < .05, ?2 = .08). Athletes in leagues that had adopted the RiSPP in 2011 reported significantly higher parental support (M = 3.88, SD = .16) compared to athletes in leagues which did not have the program (M = 3.53, SD = .43; p < .05), higher prosocial behaviours towards teammates (M = 4.58, SD = .55) than athletes in leagues that had adopted th
