Publication Open Access Substance use disorder and lifetime suicidal behaviour: a scoping review(Elsevier, 2024) Leza González, Leire; Haro Escribano, Begoña; López-Goñi, José Javier; Fernández-Montalvo, Javier; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaBackground: Suicidal behaviours are prevalent in substance use disorder (SUD) patients. These behaviours have a negative impact on the psychopathological profile of these patients. However, few studies have evaluated suicide as a continuum (i.e. starting with ideation, followed by attempts and ending with death) and its evolution during treatment. The aim of this scoping review was to explore what is known about suicidal behaviour in individuals undergoing clinical treatment for SUD. Methods: The PsycINFO, Web of Science (Core Collection and MEDLINE), Scopus, and Cochrane Library databases were searched. After screening the records based on eligibility and exclusion criteria, 30 studies were ultimately selected for inclusion. Results: Most of the studies were conducted in the USA and Europe. Only three studies evaluated suicidal behaviour with a specific instrument. The prevalence of suicidal ideation (SI) in people being treated for SUD ranged from 20 % to 62.2 %, and the prevalence of suicide attempts (SA) ranged from 15.8 % to 52.1 %. Only one study reported death by suicide. Conclusions: Despite the high prevalence of suicidal behaviours and their harmful consequences, the assessment of this phenomenon is scarce and heterogeneous. There is a need to assess suicidal behaviour with standardized criteria in order to develop tailored SUD treatment.Publication Open Access Suicidal behaviours in people seeking treatment for substance use disorder(Elsevier, 2025-03-13) Leza González, Leire; López-Goñi, José Javier; Arteaga Olleta, Alfonso; Sánchez Torres, Ana María; Fernández-Montalvo, Javier; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako GobernuaLittle 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.Publication Open Access Lifetime suicidal-related behaviour among patients in treatment for substance use disorder: a cross-sectional study(Elsevier, 2022) Siria Mendaza, Sandra; Leza González, Leire; López-Goñi, José Javier; Fernández-Montalvo, Javier; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaSuicidal-related behaviours are an important concern in individuals who present with substance use disorders (SUDs). The distinction among the specific characteristics of the different patients might help to improve prevention strategies. We describe and compare the sociodemographic characteristics, severity of addiction, and psychopathology of the participants depending on the severity of their lifetime suicidal behaviour. In addition, we examine whether the number of suicide attempts can be estimated based on the variables that differentiate the groups. A sample of 318 men and 86 women who sought treatment for addiction were assessed. The sample was divided into: no ideation or attempts, suicidal ideation, one suicide attempt, and two or more suicide attempts. The group with two or more suicide attempts exhibited a greater severity in the addiction profile. The group with one suicide attempt presented a higher psychopathological symptomatology at the time of the assessment. The severity of the Psychiatric area was related to the group with two or more attempts and to the number of suicide attempts. The presence of any number of attempts is associated with greater severity of addiction. Providing specific intervention strategies for SUD patients depending on their suicidal behaviours is promising for clinical application.
