The Association of Intrapersonal Trait Emotional Intelligence and Resilience with Suicidal Ideation in University Students.

BACKGROUND: Suicidal ideation is not restricted to psychiatric patients. To the contrary, it is not uncommon in the general population and constitutes a precursor for suicide attempts and completed suicides. While risk factors for suicidality have extensively been described, much less attention has been devoted to the investigation of protective factors. In the current study we investigated two of such potential protective factors in combination, namely trait emotional intelligence (EI) and resilience in a sample of university students. SUBJECTS AND METHODS: We recruited 277 university students without an active physical or mental disorder requiring medical attention via an online questionnaire and assessed lifetime and four-week suicidal ideation. Resilience was measured with the Connor-Davidson Resilience Scale, EI with the Self-report Emotional Ability Scale and stressful life events with the Social Readjustment Rating Scale. Logistic regression was used to investigate the effect of EI and resilience on lifetime and four-week suicidal ideation. RESULTS: Resilience as well as intrapersonal trait EI factors were significantly lower in individuals who reported lifetime suicidal ideation. The regression analysis revealed the EI facet "Regulation of one's own emotions" and the resilience factor "Control" to be significant predictors of lifetime and/or four-week suicidal ideation. Neither trait EI nor resilience had a moderating effect on the relationship between life events and suicidality. CONCLUSIONS: Low intrapersonal EI and low resilience are associated with lifetime and, in part, four-week suicidal ideation.

Neural efficiency as a function of task demands.

The neural efficiency hypothesis describes the phenomenon that brighter individuals show lower brain activation than less bright individuals when working on the same cognitive tasks. The present study investigated whether the brain activation-intelligence relationship still applies when more versus less intelligent individuals perform tasks with a comparable person-specific task difficulty. In an fMRI-study, 58 persons with lower (n = 28) or respectively higher (n = 30) intelligence worked on simple and difficult inductive reasoning tasks having the same person-specific task difficulty. Consequently, less bright individuals received sample-based easy and medium tasks, whereas bright subjects received sample-based medium and difficult tasks. This design also allowed a comparison of lower versus higher intelligent individuals when working on the same tasks (i.e. sample-based medium task difficulty). In line with expectations, differences in task performance and in brain activation were only found for the subset of tasks with the same sample-based task difficulty, but not when comparing tasks with the same person-specific task difficulty. These results suggest that neural efficiency reflects an (ability-dependent) adaption of brain activation to the respective task demands.
