Gambling disorder (GD) is a behavioral addiction associated with significant psychosocial consequences and high psychiatric comorbidity, including anxiety, depression, and impulsivity; however, the role of physical activity (PA) as a potential modulator of these alterations remains unclear. The aim of this study was to examine the relationship between PA levels and symptoms of anxiety, depression, and impulsivity in patients with GD. An observational study was conducted with 62 adults diagnosed according to DSM-5 criteria, recruited from AJUPAREVA (Valladolid, Spain). PA was assessed using the International Physical Activity Questionnaire (IPAQ), Personality trails where evaluated with CEPER III, impulsivity with the Barratt Impulsiveness Scale (BIS-11) and the Plutchik Impulsivity Scale, and anxiety and depression with the Hamilton Anxiety (HAM-A) and Depression (HAM-D) scales. Participants were predominantly male (91.5%) and reported moderate-to-high PA levels. No significant differences were found in total impulsivity across PA levels; however, motor impulsivity was higher in highly active individuals, while non-planning impulsivity was greater in those with low PA. Anxiety and depression were highly prevalent (~65%) with no significant associations with PA. In conclusion, PA was not significantly associated with psychiatric outcomes in this clinical sample, highlighting the need for larger, longitudinal studies to clarify its potential role within multidisciplinary interventions for GD.

Impulsivity is a core transdiagnostic construct in adolescent psychiatry, associated with emotional dysregulation, behavioral disorders, and increased vulnerability to mental health problems. Adolescents engaged in performing arts education may experience heightened psychosocial stressors that challenge self-regulatory capacities during a critical neurodevelopmental period. Methods: This mixed-methods study examined psychosocial and family-related factors associated with impulsivity in adolescent students enrolled in drama programs. Two focus groups with 28 upper-grade students (grades 11–12) explored subjective experiences of stress, emotional overload, and family communication. Based on these findings, a 77-item questionnaire was developed and administered to 90 ninth-grade students. Impulsivity was assessed using the Barratt Impulsiveness Scale (BIS). Results: An exploratory stepwise multiple linear regression analysis identified perceived school-related stress (β = 0.370, p < 0.001), conflictual parental communication (β = 0.273, p = 0.013), and discomfort during school discussions at home (β = 0.331, p < 0.001) as significant predictors of higher impulsivity scores. Conclusions: The findings highlight the interaction between neurodevelopmental vulnerability and environmental stressors in shaping impulsivity during adolescence. These results are clinically relevant for child and adolescent psychiatry, emphasizing the importance of early psychosocial interventions targeting stress regulation and family communication to prevent the escalation of impulsivity-related psychopathology.

Background and Objectives: The aim of this study is to evaluate impulsivity in childhood anxiety disorders and to examine its relationship with anxiety sensitivity and emotion regulation. Materials and Methods: The study group consisted of a total of 60 children aged 8–12 years diagnosed with generalized anxiety disorder (GAD, n = 30) and other anxiety disorders (n = 30). The control group consisted of 40 healthy children of similar age without a psychiatric diagnosis. Data collection forms included the Barratt Impulsiveness Scale Short Form (BIS-S), the Children’s Anxiety Sensitivity Index (ASI-3), the Emotion Regulation Checklist (ERC), and The Screen for Child Anxiety Related Emotional Disorders (SCARED). Results: Our study found no significant differences in BIS-S scores between GAD, other anxiety disorders, and the control group. The total/physical and ERC subscales of the ASI-3 were higher in the generalized anxiety disorder and other anxiety disorder group than in the control group. However, there were no significant differences in the social dimension and cognitive dimension scores of the ASI-3. It has been determined that anxiety sensitivity does not significantly mediate the relationship between emotion regulation and impulsivity, and that emotional variability/negativity is directly and completely related to impulsivity. Conclusions: Our study suggests that children with anxiety disorders experience greater difficulties in regulating their emotions compared to healthy children, and that emotional variability is directly related to impulsivity. In this context, enhancing emotion regulation skills in anxiety disorders may prove to be a pivotal factor in the efficacy of treatment and the maintenance of behavioral control. Full article

Endoscopic sleeve gastroplasty (ESG) does not produce homogeneous results, with some patients showing little weight loss after the procedure. The aim of the present study was to evaluate the ability of pre-procedural psychometric questionnaires to predict insufficient weight loss after ESG in patients with obesity. Patient candidates for ESG were requested to complete the following psychometric questionnaires: Short Form-36 (SF-36), Symptom Checklist-90 Revised (SCL-90-R), Binge Eating Scale (BES), Yale Food Addiction Questionnaire (Y-FAS), Eating Attitude Test-26 (EAT-26), and Barratt Impulsiveness Scale-11 (BIS-11). The results of the psychometric scores were then compared with the ESG outcome, which was considered a therapeutic failure if the %EWL was less than 30% at 12 months after the follow-up. Thirty-five patients (8 males and 27 females, mean age 49 years, range 21–75 years) were included in this study. At the one-year follow-up, the mean %EWL was 40 ± 43%. Male sex and higher preoperative BMI were identified as risk factors for poor weight loss. A logistic regression analysis adjusted for sex and preoperative BMI showed that low scores on the SF-36 (Subscale Mental Health), high scores on the SCL_90-R, and an elevated BES score were predictors of therapeutic failure. The results of the present study seem to confirm the usefulness of the SF-36, SCL-90R, and BES questionnaires in the selection of patients eligible for ESG. Full article

Polymathy relates to the exceptional learning abilities, in which individuals cultivate and coordinate Breadth, Depth, and integrative capability across multiple domains. It builds on mechanisms typically associated with intelligence, including abstraction, problem solving, and the transfer and integration of information. Because polymathic disposition has partial biological underpinnings, it may intersect with other biologically based individual differences, such as temperament. Biographical accounts also indicate that many polymaths did not achieve exceptional school grades, raising questions about whether the multiplicity of interests in polymaths is associated with distractibility and impulsivity, or whether there is a deeper institutional mismatch between polymaths and educational systems. Our study examined these issues using estimated high school grades across three subject areas, documented university grades, a neurochemistry-validated temperament assessment (Structure of Temperament Questionnaire; STQ-77), the Trait Polymathy Scale (TPS), the Barratt Impulsivity Scales (BIS-11), and information about aptitudes and interests from 296 participants (M/F = 152/144). Contrary to speculation that polymathy reflects distractibility, the TPS correlated negatively with the BIS-11 Lack of Attention scale and positively with the STQ-77 scales of Intellectual Endurance and Probabilistic Processing, confirming high sustained attention in polymaths. TPSs also had selective negative correlations with the STQ-77 Neuroticism scale and positive correlations with the STQ-77 Plasticity, Social Endurance, Sensation Seeking, dispositional Satisfaction scales, as well as several specific and general aptitudes and interests. These findings refine the dispositional profile linked to polymathy, highlighting the differential nature of the three components of polymathy. Full article

Background/Objectives: Suicide is a leading cause of death among adolescents. Emotion dysregulation, impulsivity, and childhood trauma are key factors underlying Self-Injurious Thoughts and Behaviors (SITB), yet reliable short-term predictors are limited, especially in at-risk clinical populations. This study prospectively examined the association between SITB and clinical (psychological pain, impulsivity, childhood trauma) and cognitive measures (Implicit Association Tests, IATs). Methods: A prospective, observational study was conducted in adolescents (12–17) admitted to a university hospital psychiatry unit following recent SITB. Participants completed the Death/Suicide IAT (D/S-IAT), Self-Injury IAT (SI-IAT), and standardized instruments including the Columbia Suicide Severity Rating Scale (C-SSRS), Difficulties in Emotion Regulation Scale (DERS), Barratt Impulsiveness Scale (BIS-11), and Childhood Trauma Questionnaire (CTQ-SF). SITB recurrence was assessed at six months. Results: Within six months, 28.9% of 38 participants reported suicidal thoughts, 15.8% engaged in self-injury, and 2.6% attempted suicide. The SI-IAT showed a small but significant correlation with C-SSRS, whereas D/S-IAT showed none. Neither IAT predicted SITB recurrence. Higher levels of emotion dysregulation and impulsivity were significantly associated with SITB. Specific DERS dimensions—emotional rejection, interference, and confusion—predicted future SITB, highlighting emotional dysregulation as a vulnerability factor. Conclusions: In high-risk adolescents, psychological pain and impulsivity predicted SITB more reliably than IATs. Unlike adult populations, explicit measures outperform implicit ones in suicide risk prediction. These findings emphasize emotion dysregulation as a key clinical construct that may intensify psychological pain and contribute to suicidal vulnerability. Full article

Background: Impulsivity is a multidimensional trait associated with the development and maintenance of behavioral and substance addictions. Genetic polymorphisms, particularly within the dopaminergic system, are thought to modulate individual differences in impulsivity. The COMT rs4680 (Val158Met) polymorphism influences enzymatic activity of catechol-O-methyltransferase and may alter dopaminergic tone in the prefrontal cortex. This study investigated whether COMT rs4680 genotype interacts with addiction status (behavioral and substance addictions) to influence trait impulsivity. Methods: The study included 309 Polish men: 128 with mixed behavioral and substance addictions and 181 healthy controls. All participants completed the Barratt Impulsiveness Scale (BIS-11) and were genotyped for COMT rs4680. A two-way ANOVA was used to assess main and interaction effects of genotype and group on total and subscale BIS-11 scores. Results: Individuals with mixed addictions scored significantly higher on all BIS-11 subscales (p < 0.01). A significant interaction effect was observed for the Non-Planning (F_2,303 = 4.40, p = 0.0131, η² = 0.028) and Total BIS-11 scale (F_2,303 = 5.77, p = 0.0035, η² = 0.037), with the A/A genotype associated with increased impulsivity, especially among the clinical group. Conclusions: These findings support a gene-by-environment interaction in impulsivity, where COMT rs4680 Met/Met homozygotes may be more susceptible to heightened impulsivity in addiction contexts. The results highlight the potential utility of COMT genotyping in personalizing therapeutic strategies for impulse-related disorders such as addictive disorders. This study extends evidence on dopaminergic modulation of impulsivity to behavioral and substance addictions. Full article

Background: Dopaminergic signaling is a key mechanism in behavioral regulation and impulse control. While DAT1 promoter methylation has been linked to behavioral dysregulation in clinical groups, its role in high-functioning populations such as elite athletes remains unclear. Objectives: To compare DAT1 promoter methylation, DAT1 VNTR genotype, and impulsivity between elite combat sport athletes and matched controls, and to assess potential gene–environment interactions. Methods: The study included 209 male participants (100 elite combat athletes, 109 controls). Methylation of 33 CpG sites within the DAT1 promoter was quantified from peripheral blood DNA. DAT1 VNTR genotypes were determined via PCR and gel electrophoresis. Impulsivity was assessed using the Barratt Impulsiveness Scale (BIS-11). Group differences and interactions were analyzed using analysis of variance (ANOVA), non-parametric tests, and post hoc comparisons. Results: Athletes displayed significantly higher overall DAT1 promoter methylation and lower impulsivity scores across all BIS-11 subscales compared with controls. A significant group × genotype interaction for methylation indicated genotype-specific epigenetic differences by athletic status. No differences in VNTR genotype or allele frequencies were observed. Conclusions: Elevated DAT1 promoter methylation in elite athletes may be associated with enhanced behavioral control, potentially reflecting neurobiological adaptations to high-intensity training. These results highlight the need to integrate genetic and epigenetic perspectives in sports science. Longitudinal and multi-omics studies are warranted to determine causal links and evaluate the potential of epigenetic markers as indicators of performance-related traits. Full article

Background and Objectives: The dopamine D2 receptor (DRD2) plays a central role in fronto-striatal circuits regulating cognitive control and reward processing. The rs1076560 polymorphism alters receptor isoform expression, potentially modifying impulsivity and vulnerability to stimulant use disorders. We examined gene–environment interactions between rs1076560 and stimulant dependence in relation to impulsivity, ADHD traits, and hedonic capacity. Methods: A total of 517 men (235 stimulant-dependent, 282 controls) completed the Barratt Impulsiveness Scale (BIS-11), Adult ADHD Self-Report Scale (ASRS v1.1), and Snaith–Hamilton Pleasure Scale (SHAPS). Genotyping for rs1076560 was performed using real-time PCR, and two-way ANOVAs tested genotype-by-group effects. Results: Significant genotype-by-group interactions were observed across all BIS-11 subscales and ASRS scores. In the stimulant-dependent group, C/C homozygotes showed the highest levels of attentional impulsivity and attentional dysregulation compared to both A/C and C/C controls. In contrast, within the control group, A/A homozygotes demonstrated higher motor impulsivity, non-planning impulsivity, and BIS-11 total scores than C/C controls. No significant main effects or interactions were found for SHAPS scores. Conclusions: DRD2 rs1076560 moderates impulsivity-related traits through dopaminergic pathways relevant to executive dysfunction in stimulant use disorders. These findings highlight a neurobiological mechanism of addiction vulnerability and may inform precision approaches in neurology and psychiatry. Full article

Background/Objectives: Suicide is the leading cause of death among South Korean military soldiers, accounting for more than 70% of all deaths. This issue is particularly relevant in the military context due to the nature of living in groups in a controlled environment. This study was conducted active-duty south Korean male soldiers aged 18 to 28 who were performing mandatory military service for one year and six months. Additionally, it compares and analyzes the differences in suicidal ideation and risk factors between military soldiers and a comparison group consisting of males in their 20s without military experience. Methods: This study included 248 Korean soldiers and 292 general controls, totaling 540 participants. The research instruments used for evaluation included the Beck Scale of Suicide Ideation (BSI), the Childhood Trauma Questionnaire (CTQ-SF), the Perceived Stress Scale (PSS), the Difficulties in Emotion Regulation Scale (DERS-16), the Barratt Impulsiveness Scale Version 11 (BIS-11), the Rosenberg Self-Esteem Scale (RSES), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder 7-item scale (GAD-7), the UCLA Loneliness Scale (UCLAS), and the State-Beck Hopelessness Scale (S-BHS). Results: The results of this study showed that suicidal ideation, depression, anxiety, impulsivity, and self-esteem were significantly higher in the military group compared to the comparison group. Conversely, emotional dysregulation was considerably lower in the soldiers than in the comparison group. No significant differences were found in childhood trauma, stress, loneliness, and hopelessness between the two groups. Multiple regression analysis within the military group revealed that childhood trauma, hopelessness, and depression were major factors influencing suicidal ideation. Conclusions: These findings will help identify risk factors for suicide among soldiers and develop effective intervention strategies to prevent it. Full article

Background/Objectives: Impulsivity is a key psychological construct implicated in the onset and maintenance of behavioural addictions. Dysregulation of impulsivity is central to behavioural addictions, yet its genetic basis remains unclear. This study examined the association between the DAT1 variable number tandem repeat polymorphism and impulsivity in individuals with behavioural addictions. Methods: A total of 328 males (128 with behavioural addictions and 200 controls) completed the Barratt Impulsiveness Scale. DAT1 genotyping was performed via PCR and gel electrophoresis. Statistical analyses included chi-square tests, Mann–Whitney U-tests, and two-way ANOVA. Results: No differences in DAT1 genotype frequencies were found between groups. However, a significant interaction emerged for attentional impulsivity: individuals with behavioural addictions and the 9/9 genotype had the highest BIS-AI scores (F_{2, 322} = 5.48; p = 0.0046). Conclusions: The DAT1 9/9 genotype may increase vulnerability to attentional impulsivity, but only in the context of behavioural addictions. These findings highlight a gene–environment interaction and support the role of dopaminergic mechanisms in cognitive dysregulation. Future studies should validate these findings using longitudinal designs and neurobiological methods. Full article

Major Depressive Disorder (MDD) is a chronic mental disorder characterized by anhedonia, loss of desire, guilt, suicidal thoughts, and appetite changes. It is reported that individuals with MDD resort to binge eating to escape from negative feelings. In this study, we aimed to determine the relationship between binge eating behavior and the concept of psychological pain associated with emotions such as shame, guilt, and anger in individuals with MDD. We conducted the study in the Psychiatry Outpatient Clinics of Balcalı Hospital, Çukurova University Faculty of Medicine. The sample consisted of 147 individuals with MDD without psychotic symptoms and 128 healthy controls with sociodemographic characteristics similar to the MDD group. We administered a sociodemographic data form, the Hamilton Depression Rating Scale (HDRS), Psychache Scale (PS), Tolerance for Mental Pain Scale-10 (TMPS-10), Barratt Impulsiveness Scale (BIS-11), and Eating Disorder Examination Questionnaire (EDE-Q-13). Eighty-two (55.7%) of the patients with MDD were diagnosed with binge eating disorder (BED). In the group of MDD patients with BED comorbidity, the EDE-Q-13 total, binging subscale, and HDRS scores were significantly higher than those of the other groups (p < 0.05 for each group), with large to very large effect sizes (e.g., EDE-Q-13 binging d = 1.04; HDRS d = 1.91; PS d = 1.22). There was no significant difference between the MDD groups (with and without BED) regarding the BIS and BIS subscales’ subscores, PS, and TMPS scores. For participants with MDD, there was a significant same-directional correlation between EDE-Q-13 binging, HDRS, BIS, and PS scores (p < 0.05 for each), with moderate to strong effect sizes (EDE-Q-13 binging and HDRS: r = 0.398, p < 0.001; binging and PS: r = 0.273, p < 0.001; binging and BIS: r = 0.233, p = 0.005; binging and TMPS-10: r = –0.257, p = 0.002). Additionally, a negative correlation was observed between TMPS and the scores for EDE-Q-13 binging, HDRS, BIS, and PS. A linear regression analysis indicated that depression severity and BMI were the strongest predictors of binge eating behavior (R² = 0.243; f² = 0.32). Based on our results, we concluded that the presence of binge eating behavior in patients with MDD is associated with more severe depressive symptoms, psychological pain, impulsivity, and lower tolerance to psychological pain. The finding that binge eating behavior was most strongly associated with depression severity and body mass index (BMI) supports the notion that binge eating behavior is a maladaptive attitude. Longitudinal studies comparing individuals with different BMIs in different clinical samples are needed to confirm our results. Full article

Substance Use Disorders (SUDs) are frequently associated with impairments in emotional regulation and behavioural control. Among the most prevalent substances of abuse, alcohol and cocaine are known to exert distinct effects on neuropsychological functioning. This study aimed to compare individuals with Alcohol Use Disorder (AUD) and Cocaine Use Disorder (CUD) in terms of impulsivity and alexithymia, and to examine the clinical implications of poly-substance use involving both alcohol and cocaine. Participants completed standardized psychometric assessments, including the Barratt Impulsiveness Scale (BIS-11), the Brief Psychiatric Rating Scale (BPRS), and the Toronto Alexithymia Scale (TAS-20). Group comparisons were conducted using non-parametric tests, and logistic regression models were applied to control for demographic covariates. The findings showed that impulsivity levels were comparable across groups, whereas alexithymia scores were significantly higher in individuals with AUD and in those with poly-substance use, relative to CUD-only participants. These findings underscore the relevance of targeting emotional regulation difficulties, particularly alexithymia, in the assessment and treatment of SUDs. Integrating emotion-focused interventions may enhance treatment outcomes, especially for individuals with co-occurring substance use patterns. Future research is needed to clarify the underlying neuropsychological mechanisms contributing to these differences and to inform more personalized approaches to addiction care. Full article

(1) Background: Self-control is an essential capacity in educating young generations for the good management of personal resources and a healthy life adapted to the constantly changing demands of technological society. Artificial intelligence is an economical and efficient solution for designing medical education programs aimed at optimizing this capacity, which can be personalized according to each personal needs and characteristics. (2) Methodology: This research is a sequential intervention study that aims to investigate if the level of impulsivity decreases and consequently the self-control in adolescents studying drama can be improved by using an online program designed for this purpose. The program’s effectiveness is evaluated by analyzing its impact on vocational performance and the reduction in unhealthy lifestyle habits. A sample of 90 subjects aged between 14 and 17 years, enrolled in the compulsory vocational education system was included in this study. The study was conducted over a five-month period and was organized in three stages: 1. The preparatory stage in which the Barratt Impulsiveness Scale was initially applied (pre-test scores); 2. Selecting the tasks for the online self-control education program and uploading the artificial intelligence network; the application of the program lasted for three months; 3. Applying Barratt Impulsiveness Scale (post-test scores). (3) Results: The results indicated both a statistically significant decrease in self-reported impulsivity and an improvement in the self-control of the sample of adolescents after three months of training on the online platform, compared to the pretest scores of impulsivity. (4) Conclusion: A comparative analysis between the initial and the final BIS scores showed a statistically significant decrease in teens‘ impulsivity, suggesting that the program was effective for this sample of adolescents. Consequently, the study findings indicate significant improvements in adolescents’ self-control after completing the three-month training program, which included cognitive-behavioral games.

Background: The present study aimed to investigate the clinical correlates of treatment response to mood stabilizers in patients with bipolar disorder (BD), with a specific focus on trait-related characteristics such as impulsivity and affective temperaments. Methods: In- and outpatients diagnosed with BD were recruited at the Section of Psychiatry of the General Hospital/University of Perugia. Socio-demographic, clinical, and current psychopathological characteristics were collected. The treatment response was retrospectively assessed using the Alda Scale. Trait characteristics were evaluated through the Barratt Impulsiveness Scale (BIS-11) and the Brief Temperament Evaluation of Memphis, Pisa, and San Diego—Münster version (briefTEMPS-M). Bivariate analyses and a general linear model were employed to analyze the correlates of treatment response to mood stabilizers. Results: Among the investigated variables, trait impulsivity showed a significant negative association with treatment response. A similar effect was observed for depressive temperament, while other affective temperaments were not significantly associated with treatment outcomes. Patients with good treatment responses exhibited higher illness duration and lower severity of BD, higher prevalence of comorbid anxiety disorders, lower diurnal variation in depressive symptoms, and lower functional impairment in autonomy and occupational domains. The main limitations of this study were represented by the small sample size, the retrospective assessment of treatment response, and the inclusion of patients from a single center. Conclusions: The present findings suggest that impulsivity and depressive temperament should be investigated as potential predictors of poor response to mood stabilizers in BD. These trait dimensions, together with other clinical markers, may serve as useful targets for patient stratification and the development of personalized treatment strategies. Full article
