Suicidal ideation, suicide plans and suicide attempts among Australian adults: Findings from the 2020-2022 National Study of Mental Health and Wellbeing.

OBJECTIVE: This study aimed to describe the epidemiology of suicidal ideation, suicide plans and suicide attempts, examine services received for suicide attempts, and explore the relationship between suicide attempts and self-harm without suicidal intent. METHODS: We used survey data from the 2020-2022 National Study of Mental Health and Wellbeing, which involved a nationally representative sample of Australian adults aged 16-85 (n = 15,893). Comparisons were made with the 2007 National Study of Mental Health and Wellbeing (n = 8841). RESULTS: In 2020-2022, the proportions of adults who had experienced suicidal ideation, suicide plans and suicide attempts during their lifetime were 16.6%, 7.5% and 4.9%, respectively. The proportions who had experienced these in the past 12 months were 3.3%, 1.1% and 0.3%. The odds of experiencing suicidal ideation and making a suicide plan were significantly higher in 2020-2022 than in 2007. Groups at heightened risk of suicidal ideation, suicide plans and/or suicide attempts in the previous 12 months were males, young people, people who were gay, lesbian, or bisexual or used some other term to describe their sexual identity, people outside the labour force, people from disadvantaged areas and people with mental disorders. Two-fifths of those who attempted suicide during the previous 12 months did not use health services following their attempt, and two-thirds also self-harmed without suicidal intent. CONCLUSION: The implications of these findings for the forthcoming National Suicide Prevention Strategy are discussed. Suicidal thoughts and behaviours confer risk for suicide and are significant problems in their own right. Their prevention requires a strong whole-of-government response.

Factors associated with the time to transition from suicidal ideation to suicide plans and attempts in the Australian general population.

BACKGROUND: Suicide plans and attempts rarely occur without prior suicidal ideation but are hard to predict. Early intervention efforts need to focus on subgroups of the population who are more likely to transition from ideation to suicidal plans and attempts. The current study utilised data from a large nationally representative sample to investigate the time taken to transition and the demographic and mental health correlates of transitioning to suicidal plans and attempts among those with suicidal ideation. METHODS: Data were from 1237 Australians aged 16-85 years who reported suicidal thoughts at some point in their life. Discrete time survival analysis was used to retrospectively examine the time in years and correlates of transitioning from suicidal ideation to suicide plans and suicide attempt. RESULTS: The majority of those who transitioned to suicide plans or attempts typically did so within 2 years of first experiencing suicidal ideation. Several factors were independently associated with increased speed to transition, including alcohol use disorder, drug use disorder, major depressive episode, obsessive compulsive disorder, sexual minority status, and non-urban location. Older age, being male, older age of first ideation and greater family support were associated with a slower transition. CONCLUSION: The current study suggests that pre-existing mental or substance use disorders, particularly drug use disorder, as well as sexual minority status, sex and greater family support play an important role in the transition from suicidal ideation to plans or attempts. These results highlight the potential importance of suicide prevention programs that aim to improve social connectedness.

Examination of interoception along the suicidality continuum.

OBJECTIVE: Interoception deficits have been associated with various points on the suicidality continuum. Most research, however, has focused on general, rather than specific facets of, interoception. This study compared individuals with lifetime suicidal ideation, plans, and attempts using a multidimensional assessment of interoception. METHOD: A total of 537 adults completed measures of their interoception and lifetime suicide histories. RESULTS: Individuals with lifetime suicidal ideation reported more worry about their bodily sensations. Those with lifetime suicide attempts reported a greater tendency to distract themselves from bodily sensations and less self-regulation using bodily sensations. Individuals at all points of the suicidality continuum reported less trust of their bodily sensations. CONCLUSION: These findings suggest that interoception may be impaired in those with a history of suicidal thoughts and behaviors. Longitudinal designs are needed to parse apart the interplay of these variables and directionality of these relationships.

SUBSTANCE USE AND SUICIDALITY: SPECIFICITY OF SUBSTANCE USE BY INJECTION TO SUICIDE ATTEMPTS IN A NATIONALLY REPRESENTATIVE SAMPLE OF ADULTS WITH MAJOR DEPRESSION.

BACKGROUND: Although several risk factors for suicidal ideation (SI) have been identified in the research literature, there is a pressing need for studies evaluating markers of risk differentiating ideators from people who have attempted. According to the interpersonal theory of suicide, habituation to painful or provocative experiences increases one's acquired capability for suicide, a necessary component for the transition from SI to attempts. This theory further posits that the acquired capability for suicide should be unrelated to risk for SI. This study tested this theory by examining injection drug use, relative to less painful means of drug use, in relation to SI, suicide plans, and suicide attempts. METHODS: Data were drawn from the National Survey on Drug Use and Health (NSDUH), a nationally representative survey conducted annually. Participants included 10,203 adults with a history of injectable drug use and major depression. RESULTS: Injection drug use was positively associated with suicide attempts (Odds Ratio [OR] = 1.66, 95% confidence interval [CI] = 1.18-2.34), but not SI or suicide plans in the full sample. Injection drug use was also associated with suicide attempts (OR = 1.64, 95% CI = 1.14-2.35), but not plans, among ideators. Lastly, injection drug use was associated with the suicide attempts among suicide planners (OR = 1.76, 95% CI = 1.01-3.06). All analyses included sex, age, race/ethnicity, family income, substance use disorder symptom severity for injectable drugs, and depressive symptom severity as covariates. CONCLUSIONS: Consistent with the interpersonal theory of suicide, injection drug use was associated with specific risk for suicide attempts but not SI or suicide plans.

Methods and associations of suicidality in Kenyan high school students: clinical and public health implications.

BACKGROUND: Most evidence on suicidal thoughts, plans and attempts comes from Western countries; prevalence rates may differ in other parts of the world. AIMS: This study determined the prevalence of suicidal thoughts, plans and attempts in high school students in three different regional settings in Kenya. METHOD: This was a cross-sectional study of 2652 high school students. We asked structured questions to determine the prevalence of various types of suicidality, the methods planned or effected, and participants' gender, age and form (grade level). We provided descriptive statistics, testing significant differences by chi-squared and Fisher's exact tests, and used logistic regression to identify relationships among different variables and their associations with suicidality. RESULTS: The prevalence rates of suicidal thoughts, plans and attempts were 26.8, 14.9 and 15.7%, respectively. These rates are higher than those reported for Western countries. Some 6.7% of suicide attempts were not associated with plans. The most common method used in suicide attempts was drinking chemicals/poison (18.8%). Rates of suicidal thoughts and plans were higher for older students and students in urban rather than rural locations, and attempts were associated with female gender and higher grade level - especially the final year of high school, when exam performance affects future education and career prospects. CONCLUSION: Suicidal thoughts, plans and attempts are prevalent in Kenyan high school students. There is a need for future studies to determine the different starting points to suicidal attempts, particularly for the significant number whose attempts are not preceded by thoughts and plans.

Covariate Health Determinants of Suicidal Ideation, Suicide Plans, and Suicide Attempts Among African American Males With and Without Major Depressive Episode.

This study aimed to examine risk of suicidal ideation, suicide plans, and suicide attempts among African American males with and without major depressive episodes while adjusting for covariates of age, education, and income. Data from the 2018 National Survey on Drug Use and Health were extracted and analyzed. We found data for 2,301 adult African American men with and without major depressive episodes, representing a population size of 13,210,069.53 in the United States. African American men with major depressive episodes were at higher risk for suicidal ideation and suicide planning than their counterparts without a major depressive episode. However, the two groups with and without major depressive episodes had equal risk chances for suicide attempts. A closer examination of suicide covariate variables among African American men with and without a major depressive episode furnishes critical distinctions between the two populations. This subtle distinction can facilitate more responsive, tailored suicide-prevention strategies for the male African American population, especially among the at-risk male adults in this group with major depressive episodes.HighlightsMajor depressive episodes significantly predicted suicidal ideation and suicide plans among African American males.After adjustment for covariates, African American males with major depressive episodes had a higher risk of suicidal ideation and suicide plans than their counterparts without a major depressive episode.After adjustment for covariates, the risk of suicide attempts remained equal among African American males.

Problem gaming and suicidality: A systematic literature review.

Background: No studies have so far synthesised the current evidence concerning a possible relationship between problem gaming and suicidality. We therefore conducted a systematic review of the literature. Our objective was to investigate the relationship between problem gaming and suicidality. The review was funded by the Norwegian Competence Center for Gambling and Gaming Research. Methods: The review was pre-registered in PROSPERO International prospective register of systematic reviews (CRD42021279774). Searches were conducted in Web of Science, PsycINFO, EMBASE, PubMed and Google Scholar, September 2021. Studies that reported data on the relationship between problem gaming and suicidality, published between 2000 and 2021, and written in any European language were included. Studies investigating internet addiction/problematic internet use and not problem gaming, specifically, and studies investigating mental health in general or mental health outcomes other than suicidality, were excluded. Data from the included studies were extracted independently by two coders who also evaluated for risk of bias using the Newcastle-Ottawa Quality Assessment Scale. The results from each included study were presented in a table. Results: A total of 12 cross-sectional studies, with in total 88,732 participants, were included in the review. In total 10 studies investigated the association between problem gaming and suicidal ideation. One of these also investigated the association between problem gaming and suicide attempts. Two studies combined suicidal ideation and suicide attempts into one variable and investigated the association between that variable and problem gaming. In total 11 of the 12 included studies found positive, crude associations between problem gaming and suicidal ideation/attempts. Five studies adjusted for possible confounding variables. Three of these still found significant associations between problem gaming and suicidal ideation, one found a positive but not statistically significant association, and the fifth found an inverse, non-significant association. Discussion: The current findings indicate that there is an association between problem gaming and suicidal ideation, and likely between problem gaming and suicide attempts. The most important limitation of the included studies is the lack of longitudinal designs. Future studies should aim to investigate the causality and mechanisms in the relationships using more stringent designs.

Premenstrual dysphoric symptoms and lifetime suicide experiences in patients with mood disorder.

BACKGROUND: Premenstrual dysphoric symptoms (PMDS) commonly co-occurred with mood disorders and correlated with suicide experiences in women. This study aims to examine the associations between PMDS and lifetime suicide experiences in patients with mood disorders. METHODS: Participants were recruited from outpatient settings of two medical centers and one psychiatric hospital in Taiwan. Women aged 18-65 in non-acute state of major depressive disorder or bipolar affective disorder were recruited. PMDS and lifetime suicide experiences were defined by the Schedule for Affective Disorder and Schizophrenia-Lifetime. Lifetime suicide experiences were defined as no suicide experience, suicide plans only and suicide attempts. RESULTS: A total of 383 women participated in this study (54.8% of them were diagnosed with major depressive disorder), and 13.8% were diagnosed with PMDS. The prevalence of patients with lifetime suicide plans only and lifetime suicide attempts were 15.9% and 39.7%, respectively. In the univariate analysis, PMDS was correlated with lifetime suicide experience. After controlling for covariates, PMDS was a risk indicator for lifetime suicide attempts (OR: 3.46, 95% CI: 1.43-8.38) but not for suicide plans only (OR: 0.93, 95% CI: 0.28-3.11). CONCLUSIONS: PMDS correlated with lifetime suicide experiences in women with non-acute mood disorders. In particular, PMDS exhibited as an independent correlate for lifetime suicide attempts.

Social media use and self-injurious thoughts and behaviors: A systematic review and meta-analysis.

Despite considerable public and scholarly debate about the role of social media in self-injurious thoughts and behaviors (SITBs), no comprehensive, quantitative synthesis of this literature has previously been undertaken. The current systematic review and meta-analysis examines associations between social media use and SITBs, including suicidal ideation, suicide plans, suicide attempts, and nonsuicidal self-injury (NSSI). A range of social media behaviors and experiences were identified, including cybervictimization and perpetration, exposure to and generation of SITB-related content, problematic use, sexting, social media importance, and frequency of use. A systematic search of PsycINFO, Medline, CINAHL, and the references of prior reviews yielded 61 eligible studies. Results largely suggested medium effect sizes for associations between specific social media constructs (cybervictimization, SITB-related social media use, problematic social media use) and SITBs. There was no association between frequency of social media use and SITBs; however, studies on this topic were limited. The majority of studies identified focused on cybervictimization, and results suggested positive associations with all SITBs, with the association between cybervictimization and suicidal ideation stronger for adolescents than adults. Overall, findings highlight the utility of examining specific social media behaviors and experiences, and point to the need for more research in this area.

Cumulative Exposure to Adverse Childhood Experience: Depressive Symptoms, Suicide Intensions and Suicide Plans among Senior High School Students in Nanchang City of China.

This study tested relationships between different types of adverse childhood experiences (ACE) and depressive symptoms, suicide intensions, suicide plans and examines the cumulative effects of adverse childhood experience on depressive, suicide intentions and suicide plans among senior high school students. We conducted a survey among five senior high schools in Nanchang city, which were selected through stratified random cluster sampling. Among the 884 respondents, 409 were male (46.27%), and 475 were female (53.73%); the age ranged from 14 to 18. During the past 12 months, 199 (22.51%) students presented to depressive symptoms, 125 (14.14%) students had suicide intensions, 55 (6.22%) students had suicide plans. As ACE scores increased, there was an increase in the odds of (1) depressive symptoms-one ACE (adjusted odds ratio, AOR = 2.096, p < 0.001), two ACEs (AOR = 3.155, p < 0.001) and three to five ACEs (AOR = 9.707, p < 0.001); suicide intensions-1 ACE (AOR = 1.831, p = 0.011), two ACEs (AOR = 2.632, p = 0.002) and three to five ACEs (AOR = 10.836, p < 0.001); and (2) suicide plans-one ACE (AOR = 2.599, p < 0.001), two ACEs (AOR = 4.748, p < 0.001) and three to five ACEs (AOR = 22.660, p < 0.001). We should increase the awareness of adolescents who have had adverse childhood experience, especially those with multiple ACEs to prevent depression and suicide among senior high school students.

Association of aggression and suicide behaviors: A school-based sample of rural Chinese adolescents.

BACKGROUND: To determine the prevalence of suicide behaviors and the associations between aggression and suicide behaviors among a nationwide school-based sample of adolescents in rural China. METHODS: A total of 16,271 students from 24 junior and 23 senior high schools in five provinces of China participated in a self-administered anonymous survey to report suicide ideation, plans, attempts, aggression and other related information. Multivariable logistic regression models were used to investigate the associations between aggression and the risks of suicide behaviors while controlling for potential confounders. RESULTS: The prevalence of suicide ideation, plans, and attempts during the past one year was 15.1%, 7.2%, and 3.5% respectively. In the fully adjusted model, participants with high level of total aggression had 4.31 times (95% CI, 3.69-5.05), 4.10 times (95% CI, 3.26-5.11), and 3.29 times (95% CI, 2.62-4.93), higher risk of suicide ideation, plans, and attempts, respectively, compared with subjects who had low level of total aggression. Moreover, high levels of all the five dimensions of total aggression also had positive associations with suicide behaviors. LIMITATIONS: This study was cross-sectional. Hence, the causal link between aggression and suicide behaviors should be verified in the future studies. CONCLUSIONS: This study suggests that aggression may be a risk factor for suicide behaviors among rural Chinese adolescents. Our findings highlight the importance of aggression treatment in suicide prevention programs. Further longitudinal studies are needed to confirm these associations.

Impulsivity and Suicidality in Adolescent Inpatients.

Suicide is the second leading cause of death among adolescents, and impulsivity has emerged as a promising marker of risk. The present study tested whether distinct domains of impulsivity are differentially associated with suicide ideation, plans, and attempts. Adolescents (n = 381; boys = 106, girls = 275) aged 13-19 years (M = 15.62, SD = 1.41) were recruited from an acute, residential treatment program. Within 48 h of admission to the hospital, participants were administered structured clinical interviews assessing mental health disorders and suicidality. Following these interviews, participants completed self-report questionnaires assessing symptom severity and impulsivity. Consistent with past research, an exploratory factor analysis of our 90-item impulsivity instrument resulted in a three-factor solution: Pervasive Influence of Feelings, Feelings Trigger Action, and Lack of Follow-Through. Concurrent analysis of these factors confirmed hypotheses of unique associations with suicide ideation and attempts in the past month. Specifically, whereas Pervasive Influence of Feelings (i.e., tendency for emotions to shape thoughts about the self and the future) is uniquely associated with greater suicidal ideation, Feelings Trigger Action (i.e., impulsive behavioral reactivity to emotions) is uniquely associated with the occurrence of suicide attempts, even after controlling for current psychiatric diagnoses and symptoms. Exploratory gender analyses revealed that these effects were significant in female but not male adolescents. These findings provide new insight about how specific domains of impulsivity differentially increase risk for suicide ideation and attempts. Implications for early identification and prevention of youth suicide are discussed.
