Role of Impulsivity and Emotion Dysregulation Dimensions on Core Characteristics of Binge Drinking among University Students.

Binge drinking refers to a pattern of alcohol consumption that leads to rapid intoxication followed by withdrawal and abstinence periods. This study aimed to investigate the potential differential contributions of impulsivity and emotion regulation difficulties to core characteristics of binge drinking (consumption speed, frequency of binge drinking episodes, and the ratio of binge drinking episodes) among a sample of non-abstainers college students. One thousand and five hundred fifty-five participants (17-25 years old) completed the UPPS-P Impulsive behavior scale, the Difficulties in Emotion Regulation Scale (DERS) and measures related to alcohol consumption patterns and affects by means of an online survey. Multiple regression analyses showed that UPPS-P sensation seeking, lack of premeditation, positive, and negative urgency dimensions were significantly associated with binge drinking core characteristics. More specifically, lack of premeditation, and sensation seeking dimensions were associated with speed of drinking, frequency of binge drinking epiosodes, and the ratio of binge drinking episodes. Positive urgency was associated with speed of drinking, and the ratio of binge drinking episodes while negative urgency was negatively associated with speed of drinking. DERS impulse dimension was associated with speed of drinking, DERS awareness dimension was negatively associated with the frequency of binge drinking episodes, and DERS goals dimension was significantly associated with the ratio of binge drinking episodes. Furthermore, patterns of drinking were independently associated with sex, depression and anxiety scores. These findings may help to plan and develop interventions aimed at addressing binge drinking in young adults by targeting impulsivity and emotion dysregulation.

Analyzing the relationship between self-efficacy and impulsivity in amateur soccer referees.

Soccer referees (SRs) are exposed to stressful situations during the competition that can affect decision-making, could be affected by impulsivity during the competition and therefore, require optimal psychological skills. The objective of this study was to ascertain and analyze the relationship between levels of impulsivity and self-efficacy of amateur SRs in the senior category. A total of 21 Spanish SRs participated in this study (age 23.57 ± 2.40 years and 7.81 ± 2.58 seasons of experience). Self-efficacy data were collected with the REFS questionnaire between 48 and 72 h before the competition. The impulsivity data were collected using the UPPS-P questionnaire 60 min before the start the competition. The results indicate that SRs with higher self-efficacy have lower levels of impulsivity, specifically in the dimensions of negative urgency (p < 0.01), positive urgency (p < 0.05), lack of premeditation (p < 0.001), and lack of perseverance (p < 0.001), as well as lower global impulsivity (p < 0.01). However, the SRs with the highest self-efficacy also obtained higher levels in the sensation seeking dimension (p < 0.05). In conclusion, the main finding of this study showed that self-efficacy is influenced by SR impulsivity prior to competition. These novel facts allow us to discover aspects related to decision-making in refereeing that can be trained to reach optimal levels.

Psychological Predictors of Homophobic Bullying Among Adolescents and Young Adults: The Role of Parental Psychological Control and Sensation Seeking

We aimed to investigate the relationship between homophobic bullying, parental psychological control and sensation seeking among adolescents and young adults and to examine the mediating role of sensation seeking. The participants included 394 adolescents and young adults aged 15 to 20 years attending the 3rd, 4th and 5th years of two public high schools in Italian cities. Participants completed the Homophobic Bullying Scale, the Dependency—oriented and Achievement—oriented Parental Psychological Control, and the Sensation—Seeking Scale. The results showed that parental psychological control predicted bullying toward gay and lesbian people. However, the two dimensions of sensation seeking (thrill and adventure seeking, and disinhibition) represented two mediators in the relationship between parental psychological control, both achievement and dependency—oriented, and homophobic bullying.

Does pregnancy make women more cautious and calm? The impact of pregnancy on risk decision-making

AbstractDuring pregnancy, a variety of psychological and physical changes occur in women, which may have different impacts on risk decision-making involving different processes systems. Based on the dual-process theories of decision-making, using the Columbia Card Task (CCT) as the experimental paradigm, which can trigger deliberative versus affective decision-makings respectively, this study recruited 240 pregnant women and non-pregnant women aged 20-40 as the experimental group and control group respectively, investigated how pregnancy impacted on women’s risk decision-making, as well as the possible roles played by a series of psychological factors (impulsivity; sensation seeking; emotional state) and physiological factors (gestational age; human Chorionic Gonadotropin, hCG; progesterone) in the above process. The results were as follows: (a) Compared with non-pregnant women, pregnant women tended to choose fewer cards, indicating a higher risk aversion consistent with a more conservative strategy, both in cold and hot CCTs; in both cold and hot CCTs, compared with pregnant women in the second trimester of pregnancy, pregnant women in the first and the third trimesters of pregnancy had a higher risk aversion tendency. (b) Pregnant women had lower levels of all dimensions of sensation seeking than did non-pregnant women, pregnant women in the third trimester of pregnancy had lower levels of Disinhibition (DIS) and Boredom Susceptibility (BS) of sensation seeking than pregnant women in the first and the second trimesters of pregnancy, but there was no significant difference in levels of emotional state or impulsivity between pregnant woman and non-pregnant women. (c) DIS of sensation seeking played a fully mediating role in the impact of pregnancy on hot CCT performance. (d) Both hCG and progesterone levels were negatively correlated with pregnant women’s hot CCT performances. (e) Positive emotion played a partial mediating role in the effect of progesterone on hot CCT performance of pregnant women.

Conceptualizing the UPPS-P model of impulsive personality through network analysis: Key dimensions and general robustness across young adulthood.

Within the UPPS-P model of impulsive personality, negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking dimensions have been linked to unique etiological mechanisms and outcomes. Yet, additional research is needed exploring direct relations among dimensions to determine how these relations may contribute to the nature of impulsive personality and its correlates. The current study used network analysis to clarify relations among UPPS-P dimensions and assess global robustness of these relations across young adulthood. Participants included a longitudinal sample of 525 college students (48% male, 18-26years) who completed the UPPS-P once per year for three consecutive years. Network structure was globally robust with particularly strong relations emerging between positive and negative urgency, as well as between lack of premeditation and lack of perseverance, across waves. Lack of premeditation consistently emerged as a central dimension. Additional analyses suggested lack of premeditation and sensation seeking as most robustly related with retrospectively reported frequency of alcohol use. Results suggested general robustness in the relations among impulsive personality dimensions, with relations involving lack of premeditation being particularly important for characterizing impulsive personality's nature. Sensation seeking and lack of premeditation may warrant particular focus when linking impulsive personality with frequency of alcohol use.

Sensation Seeking's Differential Role in Face-to-Face and Cyberbullying: Taking Perceived Contextual Properties Into Account.

Several studies have demonstrated a relationship between sensation seeking and aggression. However, few studies have examined the relationships between sensation seeking and face-to-face and cyberbullying. The few existing studies assessed sensation seeking with items partly referring to antisocial behavior. This could have led to tautological findings. Moreover, contextual properties that could account for differences between bullying contexts (face-to-face, cyberspace) were neglected. Therefore, the first goal of this study was to investigate the relationships between sensation seeking and face-to-face and cyberbullying in a way that avoids tautological findings. Thus, sensation seeking was operationalized as a motivational disposition encompassing the dimensions “need for stimulation” and “avoidance of rest.” Furthermore, students’ perceptions of the contextual properties of the face-to-face and cyber context and their relevance for the relationships between the dimensions of sensation seeking and face-to-face and cyberbullying were examined. A total of 523 students (Mage = 17.83; SD = 2.13; ♀ = 37.4%) from four vocational schools answered online questionnaires on face-to-face and cyberbullying involvement, perceived contextual properties, and the two dimensions of sensation seeking during regular school hours. Structural equation modeling revealed positive associations between need for stimulation and both forms of bullying. Avoidance of rest, however, was positively related to cyberbullying only. The differences in all regression slopes between contexts were statistically significant. That is, the positive associations with the two dimensions of sensation seeking were stronger for cyberbullying than for face-to-face bullying. Dependent t-tests revealed differences in students’ perceptions of contextual properties between contexts (face-to-face, cyberspace). Nevertheless, no significant relationships between either dimension of sensation seeking and either form of bullying were moderated by any perceived contextual property. Our results demonstrate sensation seeking’s greater role in cyberbullying and confirm differences in perceived contextual properties between the face-to-face and cyber context. Furthermore, the fact that no perceived contextual property moderated the significant relationships between the dimensions of sensation seeking and face-to-face or cyberbullying shows the relatively greater role of a single person factor compared to single contextual properties.

Flow Experience in Paragliding: Effects on Experience and Life Satisfaction

Although individuals' life satisfaction have been studied in a tourism setting, there has been limited research suggesting the flow experience as a predictor of life satisfaction. Studies investigating the antecedents of flow experience in an adventure setting are also scarce. Therefore, this study was aimed to explore the interrelationships among these constructs using a quantitative design. A sample drawn from 296 paragliding participants in Turkey was used. Structural equation modeling approach was utilized to test the research model. The results strongly supported six of seven hypotheses; the sense of control dimension was not supported. Sensation seeking dimension was first time supported as an antecedent of flow experience in paragliding activity. Challenge–skill balance and concentration were also found as strong antecedents of flow state. The direct and indirect relationships through experience satisfaction between flow experience and life satisfaction was also demonstrated in this setting. Results are discussed and recommendations are identified for adventure tourism managers.

Alexithymia, impulsivity and sensation seeking in Buprenorphine addiction: A comparative study

ABSTRACTBackground: Addiction to Subutex® can be conceptualized as a consequence of the interaction between individual, environmental and substance-related risk factors. Impulsivity, alexithymia and sensation seeking form part of the personality traits that have been implicated in the development of addiction.Methods: We conducted a cross-sectional comparative study including 50 patients with addiction to Subutex® (PSA) and 50 witnesses. We estimated alexithymia with the Toronto Alexithymia Scale(TAS-20), impulsiveness with the BARRATT Impulsiveness Scale and we assessed seeking sensation with the Brief Seeking Sensation Scale.Results: Alexithymia (total TAS-20 score superior to 56) was significantly more frequent in the PSA group (54%) compared to the control group (24%) (p < 0.05). A high level of impulsivity, was found in 60% of the PSA group participants. That rate was significantly higher than in the control group.PSA scored significantly higher in three of the four dimensions of sensation seeking as well as in the BSSS-8 total score, compared to the control group.Conclusion: Such personality traits may alter the therapeutic course and promote poly-addiction as well as riskier addictive behaviors such as using injections. Therapeutic interventions should include reducing the consequences of alexithymia, impulsivity and sensation seeking.

Relations between facets and personality domains with impulsivity: New evidence using the DSM-5 Section III framework in patients with substance use disorders.

Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition proposes an alternative diagnostic model for personality disorders based on the identification of pathological personality facets. Despite the existing evidence for the relationship between personality disorders and impulsivity in patients with substance use disorders, no study has yet been conducted within this framework. Thus, using a sample of 110 patients with substance use disorders, the present work aims to (a) analyze the relationship between the different personality facets and domains evaluated by the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PID-5) and impulsivity and (b) explore the relationships between severity of dependency and personality facets and dimensions of impulsivity. With respect to PID-5 domains, except for sensation-seeking, antagonism and disinhibition showed correlations higher than .30 with the following dimensions: urgency, premeditation, perseverance, sensation-seeking, and positive urgency (UPPS-P). The domains of detachment and psychoticism showed weaker correlations with different UPPS-P dimensions. The risk-taking PID-5 facet explains 49% variability of the sensation-seeking dimension of UPPS-P, whereas the impulsivity facet was significant on regression models computed with lack of premeditation, positive urgency, and negative urgency dimensions. Heroin and cocaine severity of dependence were moderately related to different personality facets. Lower relationships between alcohol and cannabis severity of dependence, impulsivity, and PID-5 facets were found. As a conclusion, the relationships between personality domains and impulsivity behave similarly to their five-factor equivalents for some dimensions but not for negative urgency, which might indicate the lack of specificity of this dimension of impulsivity on this type of patients.

Concordance between the original and short version of the Impulsive Behaviour Scale UPPS-P using an IRT model.

The UPPS Impulsive Behaviour Scale (with five dimensions of impulsive behaviour) is being widely used. One of the handicaps of this instrument is its relatively long administration time. This has led to the development of a short version: SUPPS-P. There are no studies comparing the relationship between the SUPPS-P scores and the original UPPS-P scores. The objectives of this study, therefore, were to analyse the psychometric properties, concordance of person measures, and efficiency of the SUPPS-P compared to those on UPPS-P, applying an Item Response Theory Model. The UPPS-P and SUPPS-P were administered to 455 undergraduate students. Confirmatory factorial analysis replicated structures reported in previous studies: the five correlated factors structure and the model with two second-order factors (Urgency and Lack of Awareness) with Sensation Seeking dimension as a different factor. Rasch analysis show that both of the instruments presented adequate model-data fit. The results show the measurement for each dimension of UPPS-P offered more precision than SUPPS-P. The structure of items location was maintained in each dimension of SUPPS-P compared to the UPPS-P, but with better person and item separation indices of the UPPS-P dimensions. The concordance analysis reveals high correlations values between scores on both versions. From the standpoint of reducing items, it can be considered that the reduced version is more efficient. This study does not support the equivalence of items on the dimensions of Sensation Seeking and Lack of perseverance.

The sensation seeking dimesion Zuckerman defined as intentional part- taking and seeking of different, new and complex situations regardless of possible physical and/or social risks, only because of the sensation itself.The investigation of the biochemical correlates of this dmiension have caused the change of the aminergic hypothesis. A new hypothesis was put forward which explains individual differences in the sensation seeking dimension on the basis of individual differences in the tonus level and the catecholamne system activity.

Correlation of Sensation Seeking with Entrepreneurship: Study on Fresh Graduate Universitas Syiah Kuala

Nowadays, getting a job is very difficult, there is no guarantee for a graduate to get a job. One of the alternatives is to become an entrepreneur. To become an entrepreneur needs self-confidence, responsibility, decision making skill, perseverance and risk taking which are in accordance with the dimensions of sensation seeking i.e. thrill and adventure seeking, experience seeking, disinhibition, and boredom susceptibility. This study aimed to understand the sensation seeking and entrepreneurship of the fresh graduates in The University of Syiah Kuala. The samples were 120 fresh graduates who were selected with quota sampling technique. There were two instruments used, Brief Sensation Seeking adaptation Scale (BSSS-8) by Hoyle et al (2002) consisting of 8 items and an Entrepreneurship Scale based on Koh’s theory (1996) consisting of 24 items. Data analysis result using Pearson correlation technique showed a correlation coefficient of (r) 0,714 with p value = 0,000 (p &lt; 0,05). The proposed hypothesis was confirmed therefore it can be concluded that there was a positive and significant correlation between sensation seeking and entrepreneurship of the fresh graduates in The Universitas Syiah Kuala.

Individual differences in the reinforcing and subjective effects of d-amphetamine: Dimensions of impulsivity.

Previous research has shown a relationship between impulsive personality and the subjective and reinforcing effects of d-amphetamine. Impulsive personality, however, is comprised of multiple dimensions. The association between different dimensions of impulsive personality and the subjective and reinforcing effects of d-amphetamine is unknown. The objective of this study was to assess the independent contributions of the "sensation-seeking" and "impulsivity" dimensions of the impulsive sensation-seeking subscale of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) to the subjective and reinforcing effects of d-amphetamine. Forty healthy emerging adults varying in scores on the sensation-seeking and impulsivity dimensions of the ZKPQ participated in a double-blind, placebo-controlled, randomized study comprised of 4 2-day blocks. Each 2-day block consisted of a sample day and self-administration day. Subjective effects and physiological measurements were taken prior to, and hourly for 3 hr following, dose administration. On sample days participants were given 8 capsules containing 0, 1, or 2 mg d-amphetamine. On self-administration days participants were able to earn capsules containing the same dose of d-amphetamine that was administered on the previous sample day by responding on a Modified Progressive Ratio Task. The "sensation-seeking" dimension was positively associated with drug taking on the Modified Progressive Ratio Task, subjective effects (e.g., "good effect"), and heart rate. However, no clear relationship between the "impulsivity" dimension and outcome measures was observed. In conclusion, these data suggest that the narrow sensation-seeking dimension of impulsive sensation-seeking is associated with initial drug liking and drug taking behavior and may be a key predictor of drug use initiation.

INVESTIGATING THE RELATIONSHIP BETWEEN ADULT ATTENTION DEFICIT AND HYPERACTIVITY DISORDER (AADHD) AND PERSONALITY CORRELATES RELATED TO SENSATION SEEKING

The scientific literature is proliferated with discussions regarding childhood ADHD and there is great awareness for it in the population. In the last 20 years, however, increasing evidence has emerged to suggest the rising and unremitting persistence of ADHD well into adulthood. Due to its chronic nature, researchers are interested in the possible personality correlates that may underlie the way in which the disorder manifests. The current research examined whether the personality trait of Sensation Seeking, and its accompanying sub-dimensions of: (i) Boredom Susceptibility; (ii) Disinhibition; (iii) Experience Seeking; (iv) Thrill and Adventure Seeking; (v) Novelty; and (vi) Intensity of stimuli can explain a statistically significant amount of adult ADHD variance. In addition to the Sensation Seeking Scale form V (SSS-V), participants were also required to complete the adult ADHD Self-Report Scale (ASRS). Significant positive correlations with adult ADHD were found for the Sensation Seeking sub-dimensions of Disinhibition and Experience Seeking. Thrill and Adventure Seeking on the other hand was found to be unrelated to ADHD in adults. Furthermore, a multiple regression analysis revealed that sensation seeking dimensions can explain a small, yet statistically significant amount of adult ADHD variance. Despite these findings, additional research is necessary to identify other possible factors that could explain adult ADHD variance. The empirical evidence regarding the role of it is scarce and inconsistent. These gaps in our understanding of the relationship between adult ADHD and personality may benefit from the identification of a moderator variable on which these relationships are contingent and that help to predict and understand when these relationships are positive and negative.

The Drug Abuse Screening Test preserves its excellent psychometric properties in psychiatric patients evaluated in an emergency setting

BackgroundSubstance use disorders (SUDs) are significant risk factors for psychiatric relapses and hospitalizations in psychiatric populations. Unfortunately, no instrument has been validated for the screening of SUDs in psychiatric emergency settings. The Drug Abuse Screening Test (DAST) is widely used in the addiction field, but is has not been validated in that particular context. The objective of the current study is to examine the psychometric properties of the DAST administered to psychiatric populations evaluated in an emergency setting. MethodsThe DAST was administered to 912 psychiatric patients in an emergency setting, of which 119 had a SUD (excluding those misusing alcohol only). The internal consistency, the construct validity, the test-retest reliability and the predictive validity (using SUD diagnoses) of the DAST were examined. The convergent validity was also examined, using a validated impulsivity scale. ResultsRegarding the internal consistency of the DAST, the Cronbach's alpha was 0.88. The confirmatory factor analysis showed that the DAST has one underlying factor. The test-retest reliability analysis produced a correlation coefficient of 0.86. ROC curve analyses produced an area under the curve of 0.799. Interestingly, a sex effect was observed. Finally, the convergent validity analysis showed that the DAST total score is specifically correlated with the sensation seeking dimension of impulsivity. DiscussionThe results of this validation study shows that the DAST preserves its excellent psychometric properties in psychiatric populations evaluated in an emergency setting. These results should encourage the use of the DAST in this unstable clinical situation.

A multidimensional approach of impulsivity in adult attention deficit hyperactivity disorder

We aimed to compare adult patients with attention deficit hyperactivity disorder (ADHD) and matched controls on four dimensions of impulsivity (urgency, lack of premeditation, lack of perseverance, and sensation seeking) and to examine the association between impulsivity and ADHD symptoms. The study was conducted on 219 participants: 72 adult ADHD patients and 147 aged and gender matched controls. All participants completed questionnaires measuring the various facets of impulsivity (UPPS Impulsive Behavior Scale), ADHD and depressive symptoms severity. Patients were also assessed for ADHD subtypes, mood disorders, and addictive behaviors. ADHD patients exhibited higher urgency, lower premeditation and lower perseverance in comparison to controls. Lack of perseverance showed the strongest association with ADHD (area under curve=0.95). Patients with combined inattentive and hyperactive/impulsive subtypes reported more frequently substance abuse problems and had higher scores on urgency and sensation seeking dimensions of impulsivity than those with predominantly inattentive subtype. We report for the first time a multidimensional evaluation of impulsivity in adult ADHD patients. The UPPS Impulsive Behavior Scale may constitute a useful screening tool for ADHD in adults and may help to further understanding the psychological mechanisms underlying the differences between the ADHD subgroups.

The role of sensation seeking and motivations for eating in female and male adolescents who binge eat

ObjectivesAlthough different personality traits have been associated with the onset and maintenance of binge eating, the role of sensation seeking is still not well documented. The aim of the present study was to investigate the role of sensation seeking and motivations for eating in male and female adolescents who binge eat. Methods336 adolescents (196 boys and 140 girls, mean age 17.48) completed a survey composed of Binge Eating Scale, Motivation for Eating Scale, and Brief Sensation Seeking Scale. ResultsOur results showed that for female adolescents, binge eating was significantly correlated with age, body mass index (BMI), Environmental and Emotional Eating. Hierarchical multiple regression analysis indicated that BMI was a significant positive predictor of binge eating; Emotional and Physical Eating accounted for 34% of the variance. For male adolescents, binge eating was significantly correlated with age, BMI, Boredom susceptibility, Experience seeking, environmental, Social and Emotional Eating. The most significant variables that contribute to binge symptoms, were age and BMI (that accounted for 16% of the variance), Experience seeking and Boredom susceptibility (11%) and emotional eating (18%). ConclusionsOur results provided support for emotional motivations as significant triggers for binge eating behavior in both male and female adolescents. Although two sensation seeking dimensions were significant predictors of binge eating in males, sensation seeking was not associated to binge eating in the female subsample.

Impulsivity moderates the association between physical activity and alcohol consumption

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, behaviors linked to the prefrontal cortex, such as impulsivity, may influence the association between physical activity and alcohol intake. The present study therefore evaluated dimensions of impulsivity as moderators of the association between physical activity and alcohol consumption. We surveyed 198 undergraduate students and obtained self-reports of their drinking habits, physical activity, and dimensions of impulsivity. We found that moderate but not vigorous physical activity was positively associated with drinking. Linear regression analyses were used to evaluate dimensions of impulsivity as moderators of the association between physical activity (vigorous or moderate) and drinks per week. Results revealed a consistent pattern of interactions between the positive urgency and sensation seeking dimensions of impulsivity and moderate physical activity on number of drinks per week. For both interactions, there was a significant positive association between moderate physical activity and drinking at higher but not lower levels of impulsivity. We conclude that impulsivity moderates the positive association between physical activity and alcohol consumption. These results have significant implications for the development of prevention and treatment programs for alcohol use disorders.

The Association Between Sensation Seeking and Well-Being Among College-Attending Emerging Adults.

Sensation seeking is a known risk factor for unsafe and reckless behavior among college students, but its association with well-being is unknown. Given that exploration plays an important psychosocial role during the transition to adulthood, we examined the possibility that sensation seeking is also associated with psychological well-being. In a large multisite US college sample (N = 8,020), scores on the Arnett Inventory of Sensation Seeking were positively associated with risk behavior, psychological well-being, and eudaimonic well-being. When sensation seeking dimensions were examined separately, well-being was found to be associated with high novelty seeking but with low intensity seeking.

Interaction effects between COMT and BDNF polymorphisms on boredom susceptibility of sensation seeking traits

Sensation seeking is a temperament associated with willingness to take risks to obtain arousal. We investigated the relationship between the polymorphisms of the COMT Val158Met and BDNF Val66Met and sensation seeking traits. The Sensation Seeking Scale (SSS) and genotyping were performed in 277 Korean healthy volunteers (165 males, 112 females). Multivariate analysis of covariance was used to test the association between the COMT and BDNF functional polymorphisms and dimensions of sensation seeking, namely, disinhibition, boredom susceptibility, experience seeking and thrill/adventure seeking. No main and interaction effects of the COMT and BDNF on SSS were observed for total subjects. However, in females, a significant gene–gene interaction effect on the boredom susceptibility of SSS was shown. Among females with COMT Met present genotype (Val/Met + Met/Met), subjects with BDNF Met absent genotype (Val/Val) had significantly higher boredom susceptibility than subjects with BDNF Met. The effects of BDNF Val66Met polymorphism on boredom susceptibility of sensation seeking traits could be modulated by COMT Val158Met polymorphism in female.
