However, ON\/obsessive\u2013compulsive (OC) symptom relationships are inconsistently reported. The current study aimed to investigate if the contribution of OC symptoms and beliefs explain variability in ON symptoms and determine if perfectionism, a transdiagnostic factor, moderates the ON\/OC symptom relationship.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The study comprised 190 participants (<jats:italic>M<\/jats:italic><jats:sub>age<\/jats:sub>\u2009=\u200928.63, <jats:italic>SD<\/jats:italic><jats:sub>age<\/jats:sub>\u2009=\u20099.88; 80% female) recruited via an undergraduate research programme, social media, advocacy organisations, and a participant registry.
