Abstract
Background: Deficits in problem-solving may be related to vulnerability to suicidal behavior. We aimed to identify the electroencephalographic (EEG) power spectrum associated with the performance of the Raven as a reasoning/problem-solving task among individuals with recent suicide attempts. Methods: This study with the case-control method, consisted of 61 participants who were assigned to three groups: Suicide attempt + Major Depressive Disorder (SA + MDD), Major Depressive Disorder (MDD), and Healthy Control (HC). All participants underwent clinical evaluations and problem-solving abilities. Subsequently, EEG signals were recorded while performing the Raven task. Results: The SA + MDD and MDD groups were significantly different from the HC group in terms of anxiety, reasons for life, and hopelessness. Regarding brain oscillations in performing the raven task, increased theta, gamma, and betha power extending over the frontal areas, including anterior prefrontal cortex, dlPFC, pre-SMA, inferior frontal cortex, and medial prefrontal cortex, was significant in SA + MDD compared with other groups. The alpha wave was more prominent in the left frontal, particularly in dlPFC in SA + MDD. Compared to the MDD group, the SA + MDD group had a shorter reaction time, while their response accuracy did not differ significantly. Conclusions: Suicidal patients have more frontal activity in planning and executive function than the two other groups. Nevertheless, it seems that reduced activity in the left frontal region, which plays a crucial role in managing emotional distress, can contribute to suicidal tendencies among vulnerable individuals. Limitation The small sample size and chosen difficult trials for the Raven task were the most limitations of the study.

Gender commonalities and differences in risk and protective factors of suicidal thoughts and behaviors: A cross-sectional study of Spanish university students. Depress Anxiety 2019; 36:1102-1114. [PMID: 31609064 DOI: 10.1002/da.22960] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 08/12/2019] [Accepted: 09/07/2019] [Indexed: 11/07/2022] Open
Abstract
AIM To assess gender differences in the association between risk/protective factors and suicidal thoughts and behaviors (STB); and whether there is any gender-interaction with those factors and STB; among Spanish university students. METHODS Data from baseline online survey of UNIVERSAL project, a multicenter, observational study of first-year Spanish university students (18-24 years). We assessed STB; lifetime and 12-month negative life-events and family adversities; mental disorders; personal and community factors. Gender-specific regression models and gender-interactions were also analyzed. RESULTS We included 2,105 students, 55.4% women. Twelve-month prevalence of suicidal ideation (SI) was 10%, plans 5.7%, attempts 0.6%. Statistically significant gender-interactions were found for lifetime anxiety disorder, hopelessness, violence between parents, chronic health conditions and family support. Lifetime mood disorder was a common risk factor of SI for both genders (Females: OR= 5.5; 95%CI 3.3-9.3; Males: OR= 4.4; 95%CI 2.0-9.7). For females, exposure to violence between parents (OR= 3.5; 95%CI 1.7-7.2), anxiety disorder (OR= 2.7; 95%CI 1.6-4.6), and alcohol/substance disorder (OR= 2.1; 95%CI 1.1-4.3); and for males, physical childhood maltreatment (OR= 3.6; 95%CI 1.4-9.2), deceased parents (OR= 4.6; 95%CI 1.2-17.7), and hopelessness (OR= 7.7; 95%CI 2.8-21.2), increased SI risk. Family support (OR= 0.5; 95%CI 0.2-0.9) and peers/others support (OR= 0.4; 95%CI 0.2-0.8) were associated to a lower SI risk only among females. CONCLUSIONS Only mood disorder was a common risk factor of SI for both genders, whereas important gender-differences were observed regarding the other factors assessed. The protective effect from family and peers/others support was observed only among females. Further research assessing underlying mechanisms and pathways of gender-differences is needed.

Zhang J, Liu Y, Sun L. Psychological strain and suicidal ideation: A comparison between Chinese and US college students. Psychiatry Res 2017; 255:256-262. [PMID: 28595148 DOI: 10.1016/j.psychres.2017.05.046] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Revised: 02/19/2017] [Accepted: 05/30/2017] [Indexed: 10/19/2022]
Abstract
OBJECTIVE This study was to explore the relation between psychological strains and suicidal ideation among Chinese and American college students. Another secondary purpose of the study was to examine the reliability of the psychological strains scales (PPS: Ref) one more time in China and the United States in college populations. METHOD Samples of college students were randomly recruited from China and United States. All of 529 college students (aged 17-27, 68.9% female) completed self-report assessments of psychological strains (Psychological Strain Scale), suicidal ideation (Beck Scale for Suicide Ideation), and indicators of psychological well-being (e.g., depression, anxiety, and stress). RESULTS Empirical results show that Psychological Strain Scales (PSS) has a good reliability. Chinese college students reported higher suicide ideation scores than American students whereas there was no statistical difference in psychological strains. Psychological strains and, depression, anxiety, and stress, were positively related to suicidal ideation in both countries. Stepwise multiple regression analysis indicated that psychological strain can significantly predict suicidal ideation. CONCLUSIONS These findings provide support for the Strain Theory of Suicide for both Chinese and American college students and some measures can be taken to reduce psychological strains in students. However, future work could extend these findings by utilizing a longitudinal design to determine whether psychological strains are in fact antecedents, and not simply correlates, of suicide ideation.
