“…Impulsivity, like suicidality, is a complicated construct consisting of many factors, rather than a unidimensional measure. 40 Thus, the subscale analysis was warranted. Sensation seekers (ie, high factor 3) have been shown to pursue novelty even at the cost of self-harm, 41 and this may explain our findings that factor 3 was correlated with DSH in both genders.…”

ObjectivesThe aim of this study was to investigate differences and similarities in risk factors for deliberate self-harm (DSH) and suicidal attempt (SA), and the role of impulsivity among a group of community adolescents.SettingThis is a cross-sectional study conducted at high schools in Northern Taiwan.Data and participantsWe recruited grade 1 students from 14 high schools. A total of 5879 participants (mean age 16.02 years, female adolescents: 57.7%) completed the online assessment.Outcome measuresParticipants completed online questionnaires about sociodemographic data, suicidality, history of DSH and SA, depressed mood, self-esteem, social support, family discord, impulsivity (Barratt Impulsiveness Scale Version 11 (BIS-11)) and the use of alcohol, tobacco and illicit drugs. A subsample was interviewed about lifetime SA, and the results were compared with those from the online questionnaires.ResultsIn our sample, 25% of the students had lifetime DSH and 3.5% had lifetime SA. Two hundred and seventy-two students received face-to-face interviews. The concordance between the online questionnaires and interviews in terms of ascertaining cases of SA was moderate (concordance rate 82.76%; kappa value 0.59). Similar risk factors for DSH/SA among the whole sample included female gender, lower academic performance, depression, substance use (tobacco and alcohol) and low self-esteem. The BIS-11 score was correlated with DSH. Factor 3 score of the BIS-11 (novelty seeking) was correlated with DSH in both boys and girls, whereas factor 2 score (lack of self-control) was correlated with SA in boys. Social support was a protective factor against SA among the female adolescents. Gender modulated the association of impulsivity and DSH/SA. Associations between impulsivity and DSH and SA were particularly strong among boys.ConclusionsRisk factors for DSH and SA were similar, but not identical. Early identification of those at risk and appropriate interventions may be helpful.

“…Many risk factors of suicide are reported previously , but variables that can differentiate attempt from ideation is less studied. One study in Chinese college students found that high motor impulsivity distinguish attempters from ideators ( P = 0.01) . As the best of our knowledge, so far there are no relevant factors to identify attempters in mood disorder patients, the known high‐risk group for suicide.…”

Risk profiles of personality traits for suicidality among mood disorder patients and community controls Objective: To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. Method: We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups. Results: All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients. Conclusion: Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt. Significant outcomes• Higher scores of neuroticism or harm avoidance were associated with increased risk of suicidal ideation and attempt, and the effect of personality traits was independent of mood disorder diagnosis.• 'High neuroticism low extraversion' or 'high novelty seeking high harm avoidance' was the risk personality profiles for suicidal behaviours.• Higher neuroticism score further distinguishes attempters from ideators among mood disorder patients. Limitations• The sample size in our study was only moderate. It is underpowered to do stratified analysis, such as identifying gender-specific effects.• Personality traits were measured after diagnosis of mood disorders. The stability of personality traits cannot be evaluated. 30

Pregnant women in general are at an increased risk of experiencing symptoms of mental illness, and those living in a developing country are even more vulnerable. Research points towards a causal relationship between unplanned pregnancy and perinatal mental illness and suggests that pregnancy planning can aid in reducing the negative impact of mental illness on a woman, her unborn baby, and the rest of the family. In this quantitative, descriptive study, we investigated both socio-demographic factors and variables relating to mental illness itself that may place women at an increased risk of experiencing unplanned pregnancy. Data was gathered at two maternal mental health clinics in Cape Town by means of semi-structured interviews. Univariate analyses of the data revealed five independent key risk factors for unplanned pregnancy: lower levels of education, unmarried status, belonging to the Colored ethnic population, substance use, and having a history of two or more suicide attempts. Some of these factors overlap with findings of similar studies, but others are unique to the specific population (women with mental illness within a developing country). Screening of women based on these risk predictors may pave the way for early interventions and reduce the incidence of unplanned pregnancy and the negative consequences thereof in the South African population.
