Addiction and Suicide: A Review

Gender Differences in Gambling Disorder: Results from an Italian Multicentric Study

Objective

Although gender-specific evidence on Gambling Disorder (GD) is still limited, some studies reported specific differences, mainly in psychopathological profiles, gambling behavior patterns, and pathogenesis. In order to further examine the role of gender in GD, we conducted a multicenter investigation in a sample of Italian outpatients.

Method

One hundred-four outpatients with a diagnosis of GD based on DSM-5 criteria were consecutively recruited at two clinics based in Milan. Socio-demographic and clinical variables were collected for the whole sample and analyzed for the effect of gender. The severity of illness was assessed using the Canadian Problem Gambling Index and the Gambling Attitudes and Beliefs (GABS).

Results

Among females, a significantly higher mean age (52.23 ± 10.95 vs. 40.96 ± 15.76; p=0.005) and older age at illness onset emerged (43.5 ± 11.92 vs. 29.22 ± 14.26; p<0.001). Females showed a significantly higher rate of psychiatric comorbidities, lifetime suicide ideation, stressful events at GD onset, and positive family history for GD compared to males. A predictive effect of male gender was found for the GABS questionnaires by performing a linear regression model, with males showing a higher risk to reach higher scores compared to females (B= 11.833; t=2.177; p=0.034).

Conclusions

Our study seems to confirm the hypotheses that gender in GD may influence psychopathological profiles, course, and comorbidity. GD in female gender is frequently a comorbid condition with other specific clinical characteristics compared to males. Identifying specific clinical factors by gender may prompt more focus on the public health of women in relation to gambling, while still recognizing that males are at-risk of earlier gambling problems. These findings should be considered in therapeutic perspectives.

Prevalence of and Factors Influencing Suicide Ideation, Attempt, and Completion in Heroin Users: A Systematic Review and Meta-Analysis

BACKGROUND

Suicide is considered a fundamental problem in discussions on public and global health. Thus, the current study aimed to review the prevalence of and reasons for successful suicide attempts in heroin users.

METHODS

This study was conducted by systematically searching the electronic databases of PubMed, Scopus, Web of Science, and PsycINFO from 1960/1/1 to 2021/11/1 based on the PRISMA checklist and using MeSH keywords with no temporal or linguistic limitations. The primary and secondary impacts of suicide were identified, and all studies following an observational design (cohort, case-control, and cross-sectional studies) were included in the research. Data analysis was performed using Stata version 13. Finally, 17 studies were included in the work process for systematic review and meta-analysis.

FINDINGS

The results showed the most frequent reasons for suicide among the studied individuals were gender (being female), youngness, heroin overdose, multi-drug abuse, history of repeated suicide attempts, history of psychiatric disorder (especially depression), joblessness, homelessness, distorted family relationships, etc. Moreover, the results of synthesizing the studies revealed the prevalence of suicide attempts equaled the effect size (95% CI=0.3 [0.23-0.37]) among these individuals, and the prevalence of successful suicides approached the effect size (95% CI=0.03 [0.01-0.05]).

CONCLUSION

The results of the present study showed the high prevalence of suicidal thoughts and suicide attempts among the heroin-abusing population. Furthermore, according to the findings, the prevalence of unsuccessful suicide attempts was ten times more than that of successful ones in the target population.

Suicidal behavior in patients with gambling disorder and their response to psychological treatment: The roles of gender and gambling preference

Suicidal ideation and attempts are prevalent among patients with gambling disorder (GD). However, patients with GD and a history of lifetime suicidal events are not a homogeneous group. The main objective of this study was to compare sociodemographic, clinical, personality, and psychopathological features among different profiles of adults with GD with and without a history of suicidal behavior, taking into account two relevant variables: gender and gambling preference. The second aim was to examine how the different profiles of patients with a history of suicidal events responded to cognitive-behavioral therapy (CBT). A total of 1112 treatment-seeking adults who met the criteria for GD were assessed at a hospital specialized unit for the treatment of behavioral addictions. The participants completed self-reported questionnaires to explore GD, personality traits, and psychopathological symptomatology. The lifetime histories of suicidal ideation and attempts, and gambling preferences, were assessed during semi-structured face-to-face clinical interviews. Of the total sample, 229 patients (26.6%) reported suicidal ideation and 74 patients (6.7%), suicide attempts. The likelihood of presenting suicidal ideation was higher for women than men, but no differences were observed based on gambling preference. Regarding suicide attempts, the odds were higher among women with non-strategic forms of gambling. Suicidal ideation and attempts were associated with higher GD severity, a worse psychopathological state and higher self-transcendence levels. In terms of treatment outcomes, neither gambling preference nor past suicidal behavior had an influence on dropouts and relapses. Nevertheless, female gender and a lack of family support constitute two good predictors of a worse treatment outcome.
