Implication for health policy/practice/research/medical education: For risky behaviors and mental disorders. The construct of impulsivity is significantly important in research and clinical fields concerning risky behaviors and some mental disorders. Although, according to DSM and ICD, impulsivity is recognized as a diagnostic criterion for several disorders (1), but the way it influences menta...

OBJECTIVE We investigated relationships among gender, impulsivity and disordered eating in healthy college students. METHOD Participants (N=1223) were healthy, undergraduate men (28.5%) and women (71.5%), who completed the Barratt Impulsiveness Scale - Version 11 (BIS-11) and a four-factor version of the Eating Attitudes Test (EAT-16). RESULTS As predicted, mean scores on all four EAT-16 fa...

Sidama people occupy a subsistence niche partitioned between traditional enset agropastoralism and transitional maize farming. Enset production is low risk and requires multiple years for cultivation and processing. Maize farming is high risk and high yield, requiring one growing season from planting to harvest. Contrasting enset and maize farming, we examine effects of crop loss and social sho...

Barrat Impulsiveness Scale 11 (BIS-11). The BIS-11 is a widely used measure of self-reported impulsivity, with higher scores reflecting greater impulsivity. In addition to an overall measure, the BIS provides three factors assessing different forms of impulsivity. Attentional Impulsivity reflects the difficulty focusing on the task at hand and experiencing racing or intrusive thoughts. Motor Im...

The loudness dependence of the auditory evoked potential [LDAEP] is a measure of brain sensitivity and a potential biological marker of central serotonergic activity. Serotonin was also known to be related with impulsivity. Hence, LDAEP may be useful to evaluate a relationship between sensory sensitivity and impulsivity. As has been reported, LDAEP is related to depression, anxiety and mood lab...

This study examined clinical characteristics and laboratory-measured impulsive behavior of adolescents engaging in either non-suicidal self-injury with (NSSI+SA; n=25) or without (NSSI-Only; n=31) suicide attempts. We hypothesized that adolescent with NSSI+SI would exhibit more severe clinical symptoms and higher levels of behavioral impulsivity compared to adolescents with NSSI-Only. Adolescen...

INTRODUCTION Internet gaming disorder (IGD) is usually defined as the inability of an individual to control internet gaming resulting in serious negative consequences, and trait impulsivity has been viewed as a hallmark feature of IGD. Recent studies have suggested that the structural integrity of the white matter (WM) plays an important role in the neuromediation of an individual's impulsivity...

Mounting evidence indicates that physical activity and alcohol consumption are positively associated, but potential moderators of this relationship remain unclear. Both physical activity and alcohol drinking are potentially reinforcing and may be more strongly associated among individuals who tend to be higher in reward seeking and related processes governed by the prefrontal cortex. Thus, beha...

BACKGROUND Theories of personality have posited an increased arousal response to external stimulation in impulsive individuals. However, there is a dearth of studies addressing the neural basis of this association. METHODS We recorded skin conductance in 26 individuals who were assessed with Barratt Impulsivity Scale (BIS-11) and performed a stop signal task during functional magnetic resonan...
