The role of negative affectivity and detachment in the relationship between dark triad personality and suicidal behavior: A chain-mediated model analysis

Background-Community attitudes about suicide and their relationship to suicidal behavior have not been adequately investigated in low-and middle-income countries.

The association between psychological strain and suicidal behaviors among college students: A mental health survey in Jilin Province, Northeast China

Background: The high burden of suicide among young adults is a matter of grave concern worldwide. Yet only a few studies from India have attempted to explore the region-specific prevalence and determinants of suicidal behavior. Considering this research gap, the present study was undertaken to capture the prevalence and sociodemographic determinants of suicidal behavior among college-going young adults residing in Delhi. Materials and Methods: This cross-sectional study was carried out among 272 (59.20% females) college-going young adults (aged 18–30 years) of Delhi. Data on sociodemographic variables were captured through a pretested and modified interview schedule. Screening for suicidal behavior was done using the Suicide Behavior Questionnaire-Revised. Statistical analysis was performed using SPSS version 22. Results: Suicidal behavior was present in 18.01% of the studied participants. The prevalence of suicidal behavior was significantly higher among females (21.73%) than among males (12.61%) (P < 0.05), suggesting females are at a higher risk than males. Other sociodemographic variables (age, education level, state of origin, social category, religion, and family income) were not found to be associated with suicidal behavior except for the social category, where participants belonging to reserved castes were found to be at relatively lower risk of having suicidal behavior than those belonging to the unreserved category. Conclusions: The prevalence of suicidal behavior among the participants is quite high. Region-specific data on suicide-related behavior is important for averting completed suicides and preventing devastating outcomes among young adults.

This study aimed to further investigate the perceived attractiveness of the Dark Triad (DT) personality in different types of relationships (i.e. friendship, short-term and long-term relationship) controlling for basic personality traits from the HEXACO model. The participants were 167 female students (M = 20.82 years, SD = 1.54) who rated personality and attractiveness of a man with highly expressed DT characteristics (n = 91) or a low-scoring DT character (n = 76) presented in a vignette. In line with recent findings, we observed a high negative correlation between the Honesty-Humility factor and DT personality (r = -.88, p < .001). As hypothesized, there was a significant difference in attractiveness ratings for the two characters in the context of different interpersonal relationships, with high DT character rated as significantly more attractive than the low DT character in the context of short-term mating. Furthermore, the hierarchical regression analysis showed that DT personality had a unique contribution in predicting attractiveness in the context of short-term relationship, after controlling for the basic personality traits.

Gender identity represents a topic of growing interest in mental health research. People with non-conforming gender identity are prone to suffer from stigmatization and bullying and often present psychiatric issues, which may in turn lead to a high prevalence of suicidal ideation and behaviors. The present meta-analysis aimed to estimate the prevalence of suicidal ideation and suicidal behaviors in gender non-conforming children, adolescents and young adults. A systematic search was performed in Web of Science and PsycINFO from inception to December 2018. We selected cross-sectional and cohort studies including youths (up to 25years) with a diagnosis confirmed by a clinician according to international classifications, or after a direct interview with a peer. A random-effects meta-analysis was computed for the following outcomes: non-suicidal self-injury (NSSI), suicidal ideation and suicide attempts. Overall, we found a mean prevalence of NSSI of 28.2% (9 studies, 3057 participants, 95% CI 14.8-47.1). A similar prevalence (28%) was found for suicidal ideation (6 studies, 2249 participants, 95% CI 15-46.3), while the prevalence of suicide attempts was 14.8% (5 studies, 1039 participants, 95% CI 7.8-26.3). Subgroup analyses revealed no significant differences according to biological sex. Given the prevalence of suicidal behaviors in gender non-conforming youths, it appears desirable to implement therapeutic and support strategies for this population. Moreover, educational interventions directed to parents, teachers, mental health professionals and general community should be promoted to struggle against stigma and social isolation, factors that may contribute to increasing the risk of suicidal behaviors.

BackgroundSuicide remains a major risk factor for individuals suffering from schizophrenia and its prodromal state (i.e., Ultra-High Risk for Psychosis). However, less is known about the prevalence of suicidal behaviour among the adolescent and youth UHR population, a demographic vulnerable to the psychosocial and environmental risk factors of suicide. This review aims to synthesise existing literature on the prevalence of suicidal ideation and behaviour in the adolescent and youth at Ultra-High Risk for Psychosis (UHR), and the associations between suicidal behaviour and its correlates.MethodsThe databases PsycINFO, PubMed, Embase, Cochrane Library, Web of Science, and Scopus were accessed up to July 2024. A meta-analysis of prevalence was subsequently performed for lifetime suicidal ideation, lifetime non-suicidal self-injury, lifetime suicidal attempt, and current suicidal ideation. A narrative review was also carried out for the correlates of suicidal behaviour amongst adolescents and youth in the UHR population.ResultsStudies were included in this meta-analysis. Meta-analysis revealed a high prevalence of lifetime suicidal ideation (58%), lifetime non-suicidal self-injury (37%), lifetime suicidal attempt (25%), and current (2 week) suicidal ideation (56%). The narrative review revealed that a personal transition to psychosis and a positive family history of psychosis were associated with suicidal attempts, while depression was associated with both suicidal attempts and suicidal ideation.ConclusionThe prevalence of suicidal ideation and behaviour among UHR adolescents and youth is high and comparable to that of the general UHR population. Existing measures that mitigate suicide risk in the general UHR population should be adopted for the youth context.

IntroductionBefore the pandemic, suicide was already considered a global public health problem. The outbreak of COVID-19, a coronavirus-related infectious disease, began to impact people's physical and mental health. The factors that either contribute to or mitigate this risk need to be better understood, and this can only be accomplished through research. Therefore, this study aimed to study the prevalence of suicidal ideation and behavior in Tamaulipas, Mexico, during the COVID-19 pandemic.MethodsA quantitative, descriptive, and cross-sectional study was conducted. The sample consisted of 659 participants, of whom 194 (29.5%) were men and 465 (70.5%) participants were oldwomen, ranging in age between 16 and 68 years (M = 22.56, SD = 7.26). An adapted version of the Spanish version of the Columbia Suicidal Severity Rating Scale was used to assess the seriousness of suicidal ideation and behavior.ResultsThe higher rates of suicidal indicators were suicidal ideation with “wish to dead” (39.9%), while the lower was suicidal ideation with a specific plan (8.2%). A total of 18.2% of participants reported “suicidal attempts before COVID-19,” of whom 40% reported “suicidal attempts in the last 3 months.” Suicidal behavior rates were lower: 13.7% of participants reported “non-specific preparatory behavior” and 13.3% reported “actual suicide attempts.” Women were more likely than men to exhibit almost all indicators of suicidal ideation and behavior (OR = 1.63–2.54; 95% CI = 1.11–2.41, 1.76–3.68), as well as confinement (OR = 2.60; 95% CI = 1.73–3.91). Confinement for more than 40 days (OR = 0.55–0.66; 95% CI = 0.40–0.75, 0.47–0.93) and knowing a person infected with COVID-19 (OR = 1.57–2.01; 95% CI = 1.02–2.42, 1.20–3.34) were associated with a higher risk of exhibiting several suicidal indicators and having previously attempted suicide.ConclusionBeing a woman, knowing a person infected with COVID-19, and being confined, especially for longer than 40 days, are all risk factors for suicidal ideation. Therefore, intervention programs are needed to reduce the suicide risk prevalence, especially these days because of the influence of the pandemic, and should be primarily focused on those who present the risk factors associated with suicidal behavior identified in this study.

Background and aimsDespite indications that the dark triad of personality might be associated with Internet-use disorder (IUD), research about these associations is lacking.MethodsTwo studies were performed to grasp the links between these variables. In the first study, a sample consisting of N = 468 participants (n = 130 males) filled in the Short Dark Triad Questionnaire to assess scores in the dark triad of personality and the short Internet Addiction Test to assess tendencies toward unspecified IUD. In the second study, another independent sample of N = 472 participants (n = 143 males) filled in the same questionnaires plus items about specific forms of IUD.ResultsTraits Machiavellianism and psychopathy were positively linked to tendencies toward unspecified IUD in both samples and males and females. Regarding the associations between tendencies toward specific IUDs and the dark triad of personality, no significant associations were found in males (at least not passing correction procedures for multiple testing). In females, trait Machiavellianism/psychopathy and tendencies toward Internet-shopping disorder, trait psychopathy, and tendencies toward Internet-pornography-use disorder as well as trait Machiavellianism and tendencies toward Internet-communication disorder were significantly positively correlated [at least one of the (sub)scales assessing the respective specific IUD was significantly associated with the respective dark triad trait even after correction procedures for multiple testing]. No robust pattern of associations between trait narcissism and unspecified/specific forms of IUD could be observed across (sub)samples.Discussion and conclusionsThese results indicate positive associations of the traits Machiavellianism and psychopathy (on a subclinical level) with tendencies toward IUD, especially unspecified IUD. The associations with tendencies toward specific forms of IUD seem more complex with differential personality correlates for each specific IUD. These associations need to be replicated.

Suicide risk may be increased in patients with Parkinson disease (PD), a common neurodegenerative condition. Mood disorders, especially depression, are prevalent in patients with PD who report suicidality. To address inconsistent results from studies of suicidal ideation and behavior in patients with PD. The study team searched MEDLINE and Embase from inception to June 14, 2023, and further screened the bibliographies of relevant studies to ensure a comprehensive search. Original studies, published in English, discussing either suicidal ideation, behavior, or both in adults with PD were included. Accepted study designs included cross-sectional, case-control, and cohort studies. Studies that only included patients with PD after deep brain stimulation were excluded. This meta-analysis was conducted in line with the PRISMA guidelines. Two authors reviewed each study and extracted the data independently, with discrepancies referred to a third independent author. Outcomes included the prevalence of suicidal ideation and behavior, measured as proportions, and the risk of suicidal behavior in patients with PD relative to controls, measured in both odds ratio (OR) and hazards ratio (HR). A total of 28 studies comprising 505 950 PD patients were included in the final analysis. The prevalence of suicidal ideation was evaluated in 14 studies (22.2%; 95% CI, 14.6-32.3) and suicidal behavior in 21 studies (1.25%; 95% CI, 0.64-2.41). Excluding 4 outliers, prevalence of suicidal behavior was significantly higher in prospective studies (1.75%; 95% CI, 1.03-2.95) than retrospective studies (0.50%; 95% CI, 0.24-1.01). Excluding 1 outlier, OR of suicidal behavior was pooled across 10 studies and significant (OR, 2.15; 95% CI, 1.22-3.78; P = .01). HR of suicidal behavior was assessed in 9 studies (HR, 1.73; 95% CI, 1.40-2.14; P < .001). This meta-analysis involving more than 500 000 patients with PD found 22.2% and 1.25% of patients with PD to have suicidal ideation and behavior, respectively. Patients with PD had 2 times the risk of suicidal behavior than controls. Early recognition and management of suicidality in PD can help reduce mortality.

The main purpose of this study aims to compare the scale level average scores of Dark Triad personality in China and the USA, as well as the correlation differences between three subscales of dark personality. The present study examined Dark Triad personality perceptions, and three big adult samples are selected in China and the USA separately (N1 = 507, N2 = 925, N3 = 1251). They all finished the Short Dark Triad (SD3) personality scale in paper-pencil or online format. Descriptive statistics of two comparison samples are presented. We took classical NHST and Bayesian method to test the cultural differences on scale scores. In Bayesian statistics, the results are relatively reliable. There are significant differences between China and the USA samples on narcissism and psychopathy, East get higher scores. China participants get lower scores than the USA on Machiavellianism. For the intercorrelations of subscales, some values and patterns are different significantly. Moreover, the results should be replicated in more research. The limitations and future directions of the present study also be discussed at the end of the study.

A Suicide-Specific Diagnosis – The Case Against

Language is a powerful indicator of psychological processes. This study analysed the language features on online social networks to understand individuals’ Dark Triad personality and need for power. Results based on data from 130 individuals using the Linguistic Inquiry and Word Count (LIWC) dictionary showed that language features such as I-words, negative emotion, and clout were positively related to Machiavellianism, which was positively associated with the need for power. We also found indirect effects of Analytic, I-words, and Social words on the need for power through Narcissism and indirect effects of Analytic and Authenticity on the need for power through Psychopathy. In addition, gender moderated the relationship between I-words and Machiavellianism, in that the relationship was stronger for men than for women. Finally, we built a regression model using language features to predict individuals’ Dark Triad and the need for power. Based on the findings, we put forward some suggestions for managers to recruit and promote appropriate employees.

The Dark Triad personality: Attractiveness to women

AimsThe aims of this systematic review are to summarise data on the prevalence of suicidal behaviours and self-harm in under 18s with Autism Spectrum Disorder (ASD) and consider the impact of Intellectual Disability (ID). It was hypothesised that the prevalence of these behaviours may be higher in under 18s with ASD than in the general population.BackgroundIn the general population, rates of self-harm and suicide in under 18s are of increasing concern. Whilst there is an emerging evidence base considering suicidality in autistic adults, less in known about the experience of under 18s. There has been very little research focused on how self-harm seen within the general population presents in the context of ASD and whether it continues to be a predictor of future suicidal behaviour. This may be partly due to self-harm being considered alongside Self-Injurious Behaviours (SIB), which have long been recognised as part of the clinical presentation of ASD and may have other functions (e.g. fulfilling sensory stimulation needs).MethodA systematic literature search was conducted in line with PRISMA guidelines. For this review, all papers that included data on prevalence of self-harm and/or suicidal behaviours in under 18s with ASD were included. Studies that only reported on the prevalence of the broader entity of SIB (characterised as stereotypic or habitual) were excluded.Result338 papers were initially identified and 9 met eligibility criteria. There was considerable variation in how different aspects of self-harm and suicidal behaviours were addressed between groups and also between population samples, making it difficult to generalise the findings. The prevalence of self-harming and suicidal behaviours ranged from 7% to 73%, indicating that this is a clinically significant problem for this patient group. The only study that considered the impact of co-existing ID did not identify significant differences between groups (ID vs no ID).ConclusionThere was variation in the reported prevalence rates but results suggested that rates of both self-harm and suicidal behaviour may be elevated in under 18s with ASD compared to the general population. This is in keeping with literature relating to autistic adults but in contrast to conclusions of a previous systematic review. This review highlights the need for further research to explore the experience of self-harm and suicidal behaviour in autistic children and young people.
