Risk Factors for Suicidal Ideation of the General Population

Abstract

The aim of this study was to investigate risk factors of suicide ideation in general population. A total of 1,116 adults were sampled with randomization in an urban area. After excluding 116 participants due to incomplete answer, 1,000 participants (500 males; mean age 39.6 ± 11.6) completed self-report questionnaire including the Center for Epidemiologic Study Depression Scale (CES-D), the Beck Scale for Suicide Ideation (BSI), the Spielberger State-Trait Anger Expression Inventory (STAXI), the Barratt Impulsiveness Scale (BIS), and questions on weekday sleep duration. Results showed higher scores on the BSI were related with higher scores on the STAXI, CES-D, a family history of psychiatric illness, and short or long sleep duration (≤ 5 or ≥ 10 hr) (adjusted R2 = 0.151, P < 0.001, P < 0.001, P = 0.001, and P = 0.008, respectively). The predictive power of the STAXI scores, the presence of psychiatric family history and short or long sleep duration was stronger in the high CES-D group with scores of 16 or higher (adjusted R2 = 0.275, P < 0.001, P < 0.001, and P < 0.001, respectively). These findings suggest that suicide idea in general population may be related with the presence of family history for psychiatric illness, depressive mood, high anger and short or long sleep duration.

Gender-Specific Factors Associated with Suicide Attempts among the Community-Dwelling General Population with Suicidal Ideation: the 2013 Korean Community Health Survey

“…In a path analysis of elderly subjects, depressive symptoms had the strongest influence on suicidal ideation and suicide attempts (27). In addition, both major and minor depression disorders are significant predictors of suicide in the old elderly (28) and depressive mood is independently associated with suicidal ideation in the general population (29).…”

Suicidal Ideation and Distress in Family Members Bereaved by Suicide in Portugal

“…In the general population, suicidal ideation is related with psychiatric illness and depressive mood (Bae, Lee, Cho, Kim, Im, & Cho, 2013) and several empirical studies linked depression, anxiety, and hostility with suicidal ideation (e.g., Campos, Besser, & Blatt, 2012, 2013Goldblatt, 2008;Lamis et al, 2010;Nepon, Belik, Bolton, & Sareen, 2010;Youssef et al, 2004).…”

Short Sleep Duration and Circadian Rhythms: Association with Suicidal Behaviour

“…There seems to be a nadir around 8-9 hours of sleep per night, depending on the population under study. Some studies suggest that above a certain number of hours of sleep (>8 hours [21], ≥9 hours [17], or ≥10 hours [41]) the risk for suicidal behaviour is also increased, although to a lesser extent than with short sleep duration or becoming non-significant after adjustment for some factors. The study conducted by Winsler et al [28], which evaluated sleep duration continuously, further suggests that even within a range of sleep time usually considered normal, having just 1 hour less of sleep (e.g.…”

“…Bae et al [41] considered shorter and longer than normal sleep duration in the same category, named "abnormal sleep duration" (≤5 or ≥10 hours of sleep). In a linear regression analysis, suicidal ideation was significantly related to abnormal sleep duration, although after controlling for age and gender the correlation was not significant.…”

“…[18,[29][30][31]), or even being in the same category as long sleep duration [41]. Furthermore, the number of categories of sleep duration considered in the analyses varied from 2 to 7, and some studies considered sleep duration as a continuous variable [28,54,55].…”
