Suicidal behaviours in people seeking treatment for substance use disorder

Little is known about the specific characteristics of suicidal behaviour in people receiving treatment for substance use disorder (SUD). The aim of this study was to describe the number and types of suicide attempts and the methods used by 215 patients with SUD, according to sex. A face to face interview (Columbia Scale Severity Rate) was conducted. Lifetime suicidal ideation was reported by 48.8 % (n = 105) of the patients, and lifetime suicide attempts by 28.4 % (n = 61). Forty-five patients reported actual suicide attempts (20.9 %), and overdose was the most common method used (52.5 %; n = 32). Women had more aborted attempts than men did. Most of the participants who attempted suicide made only one attempt (n = 34; 55.7 %). The projection of these figures is alarming. These results justify the need to integrate suicide prevention interventions into addiction treatment programmes.
