Abstract:Introduction
Methamphetamine (MA) users report higher levels of impulsivity relative to healthy controls, which may either result from, or precede, their substance use. Further, there is evidence that female MA users may be more impulsive than male MA users prior to MA use. Thus, the goal of the current study was to determine whether different subtraits of self-reported impulsivity are significantly related to age at first MA use, controlling for total years of MA use.

“…Impulsivity can be conceptualized as rapid decision making with little or no forethought, a lack of planning, and no consideration of the consequences (Petry, 2001). Reportedly, impulsivity increases susceptibility to develop stimulant use disorders (Cservenka & Ray, 2017), and stimulant use increases the likelihood of impulsivity in return (Uhlmann et al, 2016). For example, adults who are currently using methamphetamine present with increased impulsivity (Jones, Dean, Price, & London, 2016).…”
Section: The Role Of Impulsivity On the Association Between Boredom Pmentioning
Boredom proneness has been linked to aggressive behaviors; however, the relationship between them is not well understood. To better understand the mechanism underlying the relationship between boredom proneness and aggression, a serial multiple mediator model was built, where boredom proneness impacted aggression simultaneously through (a) impulsivity, (b) trait anger, and (c) impulsivity to trait anger. Using data collected among Chinese substance users, a battery of interview questionnaires was completed. Results from this study indicate a positive relationship between boredom proneness, impulsivity, trait anger, and aggression. Moreover, the mediating role of impulsivity, trait anger, and both impulsivity and trait anger in serial were found. This study reflects that the link from boredom proneness to aggression among substances users could be partially explained via impulsivity and anger.

“…In turn, low VS D 2/3 R expression in rodents has been associated with more pronounced drug use and drug liking (Dalley et al ., ; Michaelides et al ., ). In humans, several lines of evidence point to increased impulsivity as an endophenotype, or vulnerability factor, for drug use and addiction (de Wit, ; Cservenka & Ray, ; Trifilieff et al ., ).…”
Impulsivity is considered a vulnerability trait for addiction. Recently, we found trait non-planning impulsiveness measured with the Karolinska Scales of Personality was negatively correlated with dopamine D receptor availability in the ventral striatum of healthy humans. While also observed in rodents, human studies have failed to find this association with other measures of trait impulsivity. We explored whether another rodent finding, reduced ventral striatum volume with greater impulsivity, could also be observed in humans using this scale. Non-planning impulsiveness was measured in 52 healthy subjects (21 female; mean age: 33.06 ± 9.69) using the Karolinska Scales of Personality. Striatal subregion volumes, including the globus pallidus, were acquired using the Multiple Automatically Generated Templates (MAGeT-Brain) algorithm. Although failing to support our a priori hypothesis, there was a significant sex interaction in the post-commissural putamen with impulsiveness. Exploratory analyses revealed impulsiveness was negatively correlated with post-commissural putamen volumes in males, but positively correlated in females. We replicated this finding in males in an increased sample (including all 52 previous subjects) who provided impulsiveness measured by the Temperament and Character Inventory (n = 73; 32 female; mean age: 33.48 ± 9.75). These correlations by sex were statistically different from one another, the main finding with the Kasolinksa Scales of Personality surviving correction for multiple comparisons. While impulsivity may be related to reduced ventral striatal D receptors across sexes, males but not females may show significant reductions in post-commissural putamen volume. These findings have important implications for understanding biological markers underlying sex differences in drug addiction vulnerability.
“…Dikkatsizlik, sabırsızlık, yenilik arama, risk alma, heyecan arama, zarar görme ihtimalini olduğundan daha düşük hesaplama ve dışa dönüklük gibi özellikler ile kendini gösterir (3,4). Dürtüsellik, içsel ya da dışsal bir uyarana, kendisi ya da başkaları için sonucun olumlu ya da olumsuz olabileceğini düşünmeden, hızlıca ve plan yapmadan yanıt verme eğilimidir (4,5,6,7). Vuchinich ve Tucker (1988) psikoaktif madde kullanımının dürtüselliği yüksek olan bireylerde beklenen bir davranış olduğunu ifade eder (8).…”

“…Bazı psikiyatrik bozuklukların çekirdek tezahürlerinden biri olan dürtüsellik (7) üç boyutlu bir yapıda ele alınabilmektedir. Dikkatle ilişkili dürtüsellik, "odaklanma eksikliği veya konsantre olamama" olarak tanımlanırken, motor dürtüsellik, "düşünmeden davranma" ve tasarlanmamış dürtüsellik "geleceğe ilişkin tahmin eksikliği veya öngörü yetersizliği" olarak kavramlaştırılmıştır (6,18). Madde bağımlılığı aşamalı bir süreçtir ve her aşamada dürtüselliğin farklı şekillerde ele alınması gerekmektedir.…”
Objective: The use of addictive substances is usually related with many problems physical, mental and social aspects. The present study aims to examine levels of impulsiveness and aggression and the relationships between impulsiveness and aggression in substance abuse. Method: This cross-sectional study was conducted in an alcohol and addiction treatment center of a psychiatric hospital in Istanbul. In order to conduct this study, ethical committee permission was obtained from the Ethics Committee of Marmara University and official permission was obtained from hospital. The sample size was calculated using a statistical formula and the study was conducted with 126 patients. Data was collected by Demographic Information Form, Barrat Impulsivity Scale (BIS-11) and Buss Pery Aggression Scale (BPAS). The data was analyzed using descriptive statistical analysis Shapiro-Wilk test, Student's t test, Mann-Whitney U, One-way ANOVA, Kruskal Wallis and Pearson correlation analysis. Results: 92.9 % male of patients, 58.7 % were single, 40.5% high school graduates and mean age was 29.53±8.20. BIS-11 total score of the patients was 63.86 ±8:47. BPAS total score of the patients was 50.70± 20.77. Statistically significant positive peer relationships were found between averages of BIS-11 total scores, BPAS total scores and all sub-scale scores (between BIS-11 total scores and BPAS total scores r=0.299, p=0.001; physical aggression r=0.225; p=0.012; verbal aggression r=0.212, p=0.018; anger r=0.191, p=0.033; hostility r=0.373, p=0.001). Discussion: In this study, the majority of participants was male. Of substance abuse, it is seen that increased impulsivity, aggression increases overall score.
