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.

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 Publikoa
Background: 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.

Prevalence and differential profiles of people with adverse childhood experiences in treatment for substance use disorder

Adverse childhood experiences (ACEs) are prevalent in people with substance use disorder (SUD). The aims of this study were to determine the prevalence of ACEs in a specific sample of people with SUD and to analyze the specific characteristics of these patients according to gender. The studied sample consisted of 215 people seeking treatment for SUD in two clinical centers in Spain. Descriptive and comparison analyses were carried out, and a logistic regression analysis was conducted to identify the main variables related to ACEs. The prevalence of at least one ACE was 82.3%. Women reported a higher prevalence of family mental health problems (p = .045; d = 0.14) and sexual abuse (p < .001; d = 0.43) than men. The group with ≥3 ACEs showed a higher severity profile for the addiction severity and psychopathological variables than the groups with 0 ACEs and 1–2 ACEs. Logistic regression showed that problems related to the group with ≥3 ACEs in the total sample were psychiatric and legal problems and lifetime suicidal ideation (in men, family/social problems and lifetime suicidal ideation; in women, employment/support problems). This study supports the high prevalence of ACEs in people with SUD and the cumulative effect of ACEs. In addition, gender is a relevant factor. The implementation of assessments and treatment for ACEs is necessary in SUD treatment programs.

Relationship between family mental health problems and substance use disorders: a gender perspective analysis

Background: Little is known about family mental illness and substance use disorder (SUD). This casecontrol study explored the relationship between family (parents and/or siblings) mental health problems (FMHP) and lifetime substance use disorder (SUD), considering a gender perspective. Methods: A sample of 387 patients (n = 306 men, 79.1%; n = 81 women, 20.9%) was recruited from the Proyecto Hombre Navarra (Spain) addiction treatment program. Patients with (80 men; 24 women) and without (226 men; 57 women) FMHP were compared, taking sex into account. Results: The prevalence of FMHP was 26.9%, without significant differences between men (n = 80; 26.1%) and women (n = 24; 29.6%). Men with FMHP reported higher severity in family/social and psychiatric areas than those without FMHP. Women with FMHP reported a higher severity in the psychiatric area and a higher prevalence of anxiety problems, suicidal attempts, previous psychopharmacological treatments, and physical abuse than women without FMHP. Conclusions: FMHP is highly prevalent in patients with SUD. They are associated with lifetime psychopathological problems, mainly in men. Further specific research is needed to evaluate this issue to develop specific treatments tailored to the needs of patients with FMHP.

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 Publikoa
Suicidal-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.

Adverse childhood experiences (ACEs) and substance use disorder (SUD): a scoping review
(Elsevier, 2021) Leza González, Leire; Siria Mendaza, Sandra; López-Goñi, José Javier; Fernández-Montalvo, Javier; Ciencias de la Salud; Osasun Zientziak
Background: The long-term negative effects of adverse childhood experiences (ACEs) and their impact on physical and mental health has been widely studied. However, research about the relationship between ACEs and substance use disorder (SUD) diagnosis in adolescence and adulthood is still scarce. Therefore, this scoping review was conducted to collect the existing research findings to explore the relationship between the experience of ACEs and the diagnosis of SUD later in life. Methods: The PsycINFO, Medline, Scopus, Web of Science, and Cochrane Library databases were searched. After identifying the records based on eligibility and exclusion criteria, 12 studies were finally selected for inclusion. Results: Most of the studies were conducted in the USA with adult male and female participants. All studies were cross-sectional in nature and assessed ACEs retrospectively. The main conclusions of the studies were that there is a higher prevalence of ACEs in the population with SUD than in the general population, and a positive association between ACEs and the development and severity of SUD in adolescence and adulthood. Conclusions: It is difficult to make comparisons between studies and to draw solid conclusions because of the lack of standardized criteria for evaluating ACEs and due to the heterogeneity in the substance types examined. More research is needed to fully elucidate the underlying mechanism of the relationship between ACEs and SUD.
