Number of recorded comorbidities¹ in the cohort of patients with obsessive–compulsive disorder (OCD) who died by suicide (left) or attempted suicide (right) during the study period. Note that although most suicide attempters had at least one psychiatric comorbidity, over 40% of patients with OCD who completed suicide did not have any recorded psychiatric comorbidity.¹ Six groups of comorbidities are considered: namely, affective disorders, psychotic disorders, personality disorders, substance use disorders, anxiety disorders and ‘other disorders’ (including reaction to severe stress, adjustment, dissociative, somatoform and other neurotic disorders).
