Further, whether differences best reflect categorical distinctions or correlations with symptom severity is unknown. This study examined whether trait and behavioural reward indicators differentiate BN, OSFED\u2010BN, and controls, predict diagnostic status, and correlate with bulimic symptom severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Participants were 349 women (153 BN, 118 OSFED\u2010BN, 78 controls).

SPSRQ\u2010Reward predicted higher odds of BN or OSFED\u2010BN versus controls, whereas BAS\u2010Drive predicted lower odds.
