Mindfulness-based training effect on attention, impulsivity, and emotional regulation among children with ADHD: The role of family engagement in randomized controlled trials

BackgroundAttention Deficit Hyperactivity Disorder (ADHD) is among the most common psychiatric conditions affecting school-aged children, marked by diverse levels of inattention, hyperactivity, and impulsivity. Mindfulness-based training intervention throughout childhood enhances those symptoms, improving emotional regulation and well-being, hence improving their quality of life. AimTo investigate the effects of mindfulness-based training on attention, impulsivity, and emotional regulation among children diagnosed with ADHD. DesignA randomized controlled trial (RCT) was used to carry out this study. SettingThis study was conducted at the outpatient Medical National Institute in XXXX. The subjects were 60 children and their parents for the control and study groups (30 in each group). ToolsResearchers used three tools to collect the necessary data: Tool I, A Socio-demographic and Academic Data Questionnaire; Tool II, the Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS); and Tool III, The Emotion Regulation Questionnaire. ResultsThe difference in the level of attention, impulsivity, and emotional regulation between the study and control groups after the mindfulness-based training intervention was statistically significant. ConclusionMindfulness-based interventions are effective in improving inattention, impulsivity, and emotional regulation among children with ADHD and increasing their performance in all activities. Recommendations: Health care professionals should consider incorporating mindfulness-based techniques into standard treatment protocols for children with ADHD. Families should be educated about the benefits of mindfulness as family involvement appears to strengthen the effectiveness of these interventions. These programs should be accessible in schools, community centers, and therapeutic settings to guarantee general distribution.RCT: NCT XXXX, Date: XXXX.

Self-Assessment of Impulsivity in Patients with Paranoid Schizophrenia in Exacerbation and Remission

Background: impaired impulse control is thought to be an important hallmark of schizophrenia, which is closely related to the dysfunction of many of the neurophysiological systems of the central nervous system characteristic of the disease. The presence of increased impulsivity requires special attention in view of the risks associated with it, both for the patients themselves and for society. Aim of the study: to assess the presence of signs of a significant level of impulsivity in self-reporting on the Barratt scale in patients with paranoid schizophrenia in a state of exacerbation and remission. Patients and Methods: the study included two groups of patients suffering from paranoid schizophrenia both in a state of sustained remission with residual psychotic symptoms and patients in a state of exacerbation. Control group: consisted of healthy subjects. To assess impulsivity, the Barratt scale, adapted to the Russian population, was used. Results: it turned out that in both groups of patients, increased impulsivity was detected in half of the cases (54% and 46%, respectively). In the control group, only 22% had such cases. There were no differences between the groups of patients. When analyzing the ratio of indicators on different subscales of the Barratt scale, no differences were found both between the groups and in comparison, with the control group. Conclusion: the results of the study suggest that impulsivity as an element of the clinical picture, which is found in the patient’s self-report, may be an informative sign that should be taken into account when forming a psychopharmacological treatment regimen and rehabilitation programs. The Barratt scale can be used in patients with schizophrenia in everyday practice.

Predicting Alcohol Use in Undergraduates: Interactions Between Social Anxiety and Impulsivity

Background: Links between social anxiety and risky drinking in college are well documented, but the specifics of this relationship are mixed and likely complex. Impulsivity may play a critical role in enhancing vulnerability for risky drinking in individuals with social anxiety. Objectives: Here we examined how impulsivity moderates the relationship between social anxiety and alcohol use in college students. 515 undergraduates (18–24 years) who endorsed at least moderate levels of alcohol use were included. Participants completed self-report questionnaires to quantify social anxiety, impulsive personality traits, and alcohol use. A series of correlations and stepwise linear regressions were conducted to examine social anxiety, impulsivity, biological sex, and their interactions as predictors of amount of alcohol use. Results: We found that multiple facets of impulsivity moderated the relationship between social anxiety and amount of alcohol use. Social anxiety was associated with more alcohol use in participants with high lack of premeditation, while social anxiety was associated with less alcohol use in participants with low lack of premeditation, low negative urgency, and high sensation seeking. Sex interacted with social anxiety; low levels of impulsivity seemed to be protective. Conclusion: Our results demonstrate that social anxiety and certain facets of impulsivity (lack of premeditation, sensation seeking) interact to predict alcohol use in undergraduates. These findings highlight the complex and important relationships between social anxiety, impulsivity, and risky drinking in college students.

Exploring the impact of probiotics on adult ADHD management through a double-blind RCT.

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric condition often persisting into adulthood, characterized by inattention, impulsivity, and hyperactivity. Emerging research suggests a connection between ADHD and gut microbiota, highlighting probiotics as potential therapeutic agents. This study involved a double-blind, randomized controlled trial where college students with ADHD received either a multi-strain probiotic supplement or a placebo daily for three months. ADHD symptoms were evaluated using a computerized performance test (MOXO) and the MATAL questionnaire. Academic records provided performance data. Additionally, eating and sleeping habits, gastrointestinal symptoms, and anthropometrics were assessed through questionnaires before and after the intervention. Fingernail cortisol concentrations (FCC) measured the long-term activity of the hypothalamic-pituitary-adrenal axis. The findings indicated that the probiotic significantly decreased hyperactivity, improved gastrointestinal symptoms, and enhanced academic performance. A multivariate analysis identified age as a significant predictor, with younger participants experiencing greater overall benefits from the intervention. There was also a negative correlation between FCC and symptoms of attention and impulsivity. Furthermore, higher academic grades were associated with lower levels of hyperactivity and impulsivity. These results suggest a beneficial impact of probiotics on ADHD symptoms and lay the groundwork for further studies to evaluate the effects of various probiotic strains on clinical outcomes in ADHD.

Relationship between bullying victimization and murderous behaviors and impulsivity's mediating role: Evidence from Chinese early adolescents.

Evidence suggests a robust relationship between experiencing bullying victimization (BV) and engaging in murderous behaviors among adolescents. However, the potential mediating effect of impulsivity on the relationship between BV and murderous behaviors in early adolescents remains underexplored. A total of 5724 adolescents, with a mean age of 13.5years, were enrolled from three middle schools in Anhui Province, China. Participants completed self-report questionnaires detailing their experiences with bullying, impulsiveness, and murderous behaviors. To assess the relationship between BV and murderous behaviors, multivariate logistic regression and Poisson regression analyses were conducted. Mediation analysis was performed using structural equation modeling. After controlling for confounding factors, a positive association was found between experiencing BV and engaging in murderous behaviors (p<0.05). Mediation analysis revealed a significant indirect effect of BV on the occurrence of murderous behaviors through impulsivity (indirect effect=0.027, 95% CI: 0.021, 0.033). BV appears to heighten levels of impulsivity, which in turn increases the likelihood of murderous behaviors. Additionally, sex-specific analysis indicated that impulsivity played a greater mediating role in the link between verbal and relational BV and murderous behaviors in females, while physical and cyber BV were more significant in males. Our findings underscore the necessity of early targeted interventions for adolescents experiencing BV and exhibiting high levels of impulsivity to mitigate their risk of engaging in murderous behaviors.

Eating disorder debut cases during COVID-19 lockdown in adults. Exploring differences in treatment outcome contrasting with pre-pandemic onset cases.

Despite an increase in eating disorder (ED) cases during the COVID-19 pandemic, there are limited longitudinal studies exploring treatment outcomes. The aims of the present study were: (1) to compare the clinical features of patients with EDs whose onset was during the COVID-19 lockdown (pandemic cohort) against patients with EDs whose onset was prior to the pandemic (pre-pandemic cohort) and, (2) to compare therapy responses between the cohorts. The sample consisted of 115 adult women with an ED. N=37 new ED cases (pandemic cohort) were diagnosed and included in the study during the pandemic (May 2020-May 2021); these patients did not have any previous history of an ED. We also included N=78 ED cases (pre-pandemic cohort) diagnosed prior to the COVID-19 pandemic breakout (prior to March 2020). All ED subtypes were considered in both groups and several clinical variables were assessed. At baseline, pandemic cohort reported lower levels of impulsivity and higher emotional regulation capacities than the pre-pandemic cohort; however, no differences were found in aspects of general psychopathology and ED related severity. Following treatment, the pandemic cohort showed higher rates of good outcome and lower rates of dropouts than the pre-pandemic cohort. Although both cohorts showed similar ED-related symptoms and general psychopathology scores, treatment outcomes were more favourable in the pandemic cohort.

Influence of parental mediation and social skills on adolescents' use of online video games for escapism: A cross-sectional study.

The widespread use of video games among adolescents has raised concerns about their impact on psychological and social development. This study aimed to assess the effects of different types of parental mediation on adolescents' tendency to use video games to avoid negative emotions and determine the relationship between adolescents' interpersonal skills and their reliance on online video games for escapism. Participants were 452 adolescents from 15 middle and high schools. Data on sociodemographic information, gaming habits, parental control of online gaming, interpersonal skills, and reasons for playing online games were also collected. Hierarchical multiple regression was used to analyze the data, with online video game escapism as the dependent variable. Results supported the study's hypothesis that both parental mediation and adolescent interpersonal skills significantly predict the use of online video games for escapism. Higher levels of parental monitoring were associated with a lower tendency of adolescents to use video games to escape negative emotions, while parental mediation supporting autonomy showed a similar but weaker protective effect. At the same time, parental monitoring was also found to be associated with lower interpersonal skills, notably higher impulsivity, narcissism, and stress in social situations. In addition, adolescents with higher levels of impulsivity were more likely to use video games for escapism. These findings highlight the importance of balanced parental involvement and the development of adolescents' social skills to mitigate the risks of problematic online gaming. Interventions should promote effective parental mediation strategies and enhance adolescents' interpersonal skills to reduce their tendency to use video games as a coping mechanism for real-life challenges. Effective parental mediation and improved interpersonal skills are critical for promoting healthier gaming habits and reducing adolescent escapism.

Characterizing impulsivity in individuals with methamphetamine and methcathinone use disorders.

Individuals with substance use disorder (SUD) are characterized by loss of control in drug use, such as increased impulsivity. Methamphetamine and methcathinone are psychostimulants, the use of which is accompanied by a high level of impulsivity. Whether individuals with methamphetamine use disorder (MUD) and methcathinone use disorder (MCUD) differ in different aspects of impulsivity is unclear. We investigated impulsivity traits and behaviors in individuals with MUD and MCUD. The Barratt Impulsiveness Scale (BIS), Sensation Seeking Scale (SSS), and delay discounting task (DDT) were assessed in individuals with MUD and MCUD and in healthy controls (HCs); then, we performed network-based analysis and computational modeling to understand the potential differences among the three groups. MUD subjects scored higher than MCUD subjects in terms of motor impulsivity, nonplanning impulsivity, and total BIS scores. The network analysis revealed that there were no significant differences between MUD and MCUD subjects in any centrality indices. The discount rate of MUD and MCUD subjects was significantly greater than that of HCs, whereas there was no difference in the discount rate between the two addiction groups. These findings suggest that MUD and MCUD participants differ in impulsivity traits but not in impulsive behaviors, implying that impulsive traits and behaviors represent different aspects of impulsivity.

Functional Brain Network of Trait Impulsivity: Whole-Brain Functional Connectivity Predicts Self-Reported Impulsivity.

Given impulsivity's multidimensional nature and its implications across various aspects of human behavior, a comprehensive understanding of functional brain circuits associated with this trait is warranted. In the current study, we utilized whole-brain resting-state functional connectivity data of healthy males (n = 156) to identify a network of connections predictive of an individual's impulsivity, as assessed by the Barratt Impulsiveness Scale (BIS)-11. Our participants were selected, in part, based on their self-reported BIS-11 impulsivity scores. Specifically, individuals who reported high or low trait impulsivity scores during screening were selected first, followed by those with intermediate impulsivity levels. This enabled us to include participants with rare, extreme scores and to cover the entire BIS-11 impulsivity spectrum. We employed repeated K-fold cross-validation for feature-selection and used stratified 10-fold cross-validation to train and test our models. Our findings revealed a widespread neural network associated with trait impulsivity and a notable correlation between predicted and observed scores. Feature importance and node degree were assessed to highlight specific nodes and edges within the impulsivity network, revealing previously overlooked key brain regions, such as the cerebellum, brainstem, and temporal lobe, while supporting previous findings on the basal ganglia-thalamo-prefrontal network and the prefrontal-motor strip network in relation to impulsiveness. This deepened understanding establishes a foundation for identifying alterations in functional brain networks associated with dysfunctional impulsivity.

Engagement in New Gambling Practices and its Association with Gambling Disorder, Impulsivity, and Cognitive Distortions: Findings from a Nationally Representative Sample of Spanish Gamblers.

Most epidemiological surveys focus on adult gambling behaviors related to traditional gambling forms, while studies on novel forms often focus on loot boxes and cryptocurrency trading individually. This study examines the co-ocurrence of emergent gambling and gambling-like practices, analyzing the demographic and psychological characteristics of involved gamblers. A cross-sectional study surveyed 1429 Spanish individuals aged 18-65, using a web-based questionnaire. The survey assessed participation in 19 gambling (e.g., lotteries, sports betting) and gambling-like activities (e.g., trading of cryptocurrencies and other assets, buying loot-boxes), along with sociodemographic and substance use. Problem gambling (PGSI), Impulsivity (UPPS-P), and cognitive distortions (Labrador's cognitive distortions scale) were also assessed. Participants who gambled over the past year (n = 921) were classified into four groups: traditional gambling (TG) only (64.5%, n = 594), TG with trading activities (27.5%, n = 253), TG with gambling withing video games or streaming platforms (2.5%, n = 23), and TG with both trading and video gambling (5.5%, n = 51). Most gamblers engaged exclusively in traditional formats, but 35.5% also participated in novel gambling forms. Those involved in both trading and video gambling were generally younger, male, with higher levels of impulsivity and gambling-related cognitive distortions compared to TG-only gamblers (p < 0.001). This group also exhibited higher rates of problem gambling and substance use (p < 0.001). This study emphasize the importance of including emerging gambling activities, which are particularly prevalent among high-risk gamblers, in epidemiological surveys. Identifying new gambling patterns and associated risk factors could help optimize public policies and develop more effective regulatory and prevention strategies.

Glycated hemoglobin, type 2 diabetes, and poor diabetes control are positively associated with impulsivity changes in aged individuals with overweight or obesity and metabolic syndrome.

Impulsivity has been proposed to have an impact on glycemic dysregulation. However, it remains uncertain whether an unfavorable glycemic status could also contribute to an increase in impulsivity levels. This study aims to analyze associations of baseline and time-varying glycemic status with 3-year time-varying impulsivity in older adults at high risk of cardiovascular disease. A 3-year prospective cohort design was conducted within the PREDIMED-Plus-Cognition substudy. The total population includes 487 participants (mean age = 65.2 years; female = 50.5%) with overweight or obesity and metabolic syndrome. Insulin resistance (HOMA-IR), glycated hemoglobin (HbA1c), presence of type 2 diabetes mellitus, and type 2 diabetes control were evaluated. Impulsivity was measured using the Impulsive Behavior Scale questionnaire and various cognitive measurements. Impulsivity z-scores were generated to obtain Global, Trait, and Behavioral Impulsivity domains. Linear mixed models were used to study the longitudinal associations across baseline, 1-year, and 3-year follow-up visits. HOMA-IR was not significantly related to impulsivity. Participants with higher HbA1c levels, type 2 diabetes, and poor control of diabetes showed positive associations with the Global Impulsivity domain over time, and those with higher HbA1c levels were further related to increases in the Trait and Behavioral Impulsivity domains over the follow-up visits. These results suggest a potential positive feedback loop between impulsivity and glycemic-related dysregulation.

Compulsive buying disorder: Conceptualization based on addictive, impulsive, and obsessive-compulsive features and comorbidity

BackgroundThis study sought to examine the conceptualization of compulsive buying disorder in a sample of adults drawn from the community and its associated mental health correlates. MethodsAn online survey of “Personality, Mental Health, and Well-Being” was distributed to 300 adults aged 18–75 years. The survey measured a range of behaviors, such as buying behavior, alcohol and drug use, impulse control disorders, and dimensional constructs of impulsivity and obsessive-compulsiveness. ResultsA total of 294 participants (54.7% female) completed the survey and were included in the analysis. The overall frequency of probable compulsive buying disorder was 5.4% (n = 16). Compared to adults without compulsive buying disorder, those with probable compulsive buying disorder were significantly less likely to identify as heterosexual and were significantly more likely to endorse attention-deficit hyperactivity disorder, drug use problems, symptoms of borderline personality disorder, binge eating disorder, and had higher levels of compulsivity plus impulsivity. ConclusionCompulsive buying disorder appears to be fairly common in adults and appears to have symptom or diagnostic overlap with obsessive-compulsive problems, addictive disorders, and impulse control disorders. Findings highlight the need for careful clinical screening to identify often overlooked comorbidities and treat them on an individual patient basis, as well as the need to conduct high-quality clinical trials for compulsive buying disorder itself and to explore its presentation longitudinally at large scale.

Impulsivity mediates the relationship between sleep quality and interpersonal functioning: a cross-sectional study in a sample of university students

BackgroundAmid the current mental health pandemic, research continues to investigate potential contributors associated with increasing levels of negative mental health. Among such contributors is sleep, which is vital for physiological and psychological functioning with potential downstream behavioral consequences, including in relation to impulsivity and social functioning. Given the significant rates of disordered sleep behaviors reported in the literature, our study sought to investigate the relationship between sleep quality, impulsivity and interpersonal functioning among university students.MethodsAn anonymous online survey was administered to university students (Ages 18 + ; N = 526; 33% male, 67% female) addressing demographics, sleep quality, impulsivity, and interpersonal functioning.ResultsOur findings indicate a substantial proportion of students reporting poor sleep quality and impulsivity. Moreover, higher levels of impulsivity and lower interpersonal functioning were associated with poor sleep quality. Mediation analysis revealed a significant mediating role of attentional impulsivity in the relationship between sleep quality and interpersonal functioning.ConclusionsRepeated reports of significant levels of impulsivity underlying numerous psychiatric disorders, its prevalence socially, and the fundamental issue that impulsivity reflects (i.e., lack of self-control/self-discipline/self-regulation), suggests a necessity to reorient therapeutic efforts towards the root of the problem. Thus, efforts should seek to maximize preventative behaviors that strengthen the individual (e.g., improving sleep-related behaviors), and contribute to the building of character/virtue, through self-discipline, perseverance and consistency, in order to reduce negative outcomes (e.g., impulsivity, dysfunctional interpersonal functioning).

Prevalence and Influencing Factors of Body-focused Repetitive Behaviors in Turkish Medical Students

Background/Aims: Body-focused repetitive behaviors (BFRBs) such as skin-picking, trichotillomania, nail-picking, nail-biting, lip-biting and skin-biting have adverse physical and psychological effects. This study aimed to investigate the prevalence and associated factors of BFRBs in a sample of Turkish medical students. Methods: An online survey was used to investigate the prevalence of six BFRBs —skin-picking, trichotillomania, nail-biting, nail-picking, lip-biting and skin-biting-- and psychological factors such as anxiety, depression, stress levels, impulsivity and difficulties in emotional regulation (DER) in a sample of 200 medical students. Skin Picking Scale-Revised (SPS-R), Massachusetts General Hospital Hairpulling Scale (MGH-HPS), Depression Anxiety Stress Scales-21 (DASS-21), Barratt Impulsiveness Scale–Short Form and Difficulty in Emotion Regulation Scale—Brief Form and specific questions for four BFRBs (nail-picking, nail-biting, lip biting and skin biting) were administered. Results: The prevalence of at least one BFRB disorder was 28.0% (n=56). The most common diagnoses were skin-picking (17.0%) and trichotillomania (10.5%), followed by skin-picking (9.0%), lip biting (8.5%), nail-picking (7%) and nail-biting (5.0%). The gender difference was found only in skin-picking disorders (females=22.9%; males=8.5%). Students with BFRB disorder (n=56) were found to have higher levels of anxiety, depression, stress, impulsivity and DER. Students in 2nd, 3rd and 5th grade are more likely to have BFRB disorders than interns. DER was a partial mediating variable between impulsivity and the presence of BFRB disorder. Conclusions: The findings of the study suggest that BFRBs are common among medical students and that these behaviors are associated with psychological factors such as depression, anxiety, stress levels, impulsivity and difficulties in emotion regulation. Screening programs and intervention strategies for BFRBs in medical students should be developed, and it is recommended that psychological factors should be considered in these interventions, emotion regulation and stress management skills should be significantly improved, and comorbid depression and anxiety should be treated.

Negative and positive urgency as pathways in the intergenerational transmission of suicide risk in childhood.

Parental suicide attempts and suicide death increase suicide risk in their offspring. High levels of impulsivity have been observed in families at high risk for suicide. Impulsivity, a highly heritable trait that is especially elevated in childhood, is frequently measured with the UPPS-P Impulsive Behavior Scale, which includes negative urgency, positive urgency, sensation seeking, premeditation, and perseverance. Our study examined the association between the UPPS-P facets and suicide ideation (without suicide attempts) and suicide attempts at baseline and first-time endorsement within the next two years in childhood. We also examined how the UPPS-P facets mediated the association between parental suicide attempts and suicide death and offspring first-time suicide ideation and attempts at follow-up. The sample was 9,194 children (48.4% female; 9-10 years old) from the Adolescent Brain Cognitive Development (ABCD) study, assessed yearly three times. At Time 1 (T1), caregivers reported on suicide attempts and suicide deaths (combined) of the biological parents. Caregivers and children reported on suicide ideation and attempts in the KSADS-PL DSM-5 at each time point, T1 and follow-up (T2 and/or T3). The Short UPPS-P Scale (child-report) assessed the impulsivity facets at T1, which were computed as latent variables. At T1, 6.7% of children had a parent who had attempted or died by suicide. Most UPPS-P facets were associated with suicide ideation and attempts at T1 and T2/T3. In adjusted models, parental suicide attempts and suicide death were associated with offspring negative and positive urgency. In mediation models, parental suicide attempts and suicide death had an indirect effect on offspring first-time suicide ideation at T2/T3 through negative urgency (OR = 1.04; 95% CI, 1.01-1.08) and positive urgency (OR = 1.03, 95% CI, 1.01-1.05). Similar results were found for first-time suicide attempts at T2/T3. Our findings support an impulsive pathway in the familial transmission of suicide risk. For all youth, interventions that target multiple UPPS-P facets may help prevent or reduce suicide risk. For offspring whose parents have attempted or died by suicide, clinicians should pay particular attention to children who impulsively act on extreme emotions, as they may be at higher suicide risk.

Gender and trait rumination moderates the link between trait impulsivity and gambling problems severity in young adults

AimsTrait impulsivity and trait rumination appear to uniquely contribute to problem gambling. However, only a limited number of studies have investigated their relationship with each other, and no study has tested whether their interplay could explain problem gambling. In this study, we aimed to examine these associations, especially focusing on the putative moderator role of gender. MethodsThe present study utilized data from the first wave of the Budapest Longitudinal Study, representatively surveying young adults. The final, weighted sample consisted of N = 1202 (649 men; mean age = 28.04 years; SD = 4.31) participants who reported gambling in the past year. Gambling severity was assessed by the Problem Gambling Severity Index (PGSI), trait impulsivity was measured by Barratt Impulsiveness Scale short form (BIS-R-10), while rumination was assessed by the short version of Ruminative Response Scale (RRS). ResultsMultiple linear regression analysis showed significant positive association between impulsivity and problematic gambling, and we found that both trait rumination and gender moderated this association, even after controlling for depressed mood, age, level of education, and subjective relative wealth. For men, when the level of trait rumination was high, higher levels of trait impulsivity were associated with an increase in gambling problems. However, these associations were not found among women. ConclusionsOur results suggested that the interplay of trait rumination and trait impulsivity might contribute to problem gambling, potentially by the impulsive desire to alleviate negative mood states. Our results also revealed that these associations could be stronger among men than in women.

Generation Z Impulse Buying Analysis on Shopee in Special Region of Jakarta

The rise of e-commerce has made online shopping increasingly convenient, leading consumers to often make purchases driven by emotional factors rather than careful planning. This behavior is characterized as impulsive buying, where decisions are made spontaneously. Understanding the various categories of impulsive buying is essential for companies, as it enables them to tailor marketing strategies effectively. This study focuses on assessing the impulsive buying tendencies of Generation Z consumers in Jakarta's Special Capital Region while identifying their specific impulsive buying type categories. The research evaluates dimensions such as Pure Impulse Buying, Reminder Impulse Buying, Suggestion Impulse Buying, and Planned Impulse Buying, alongside Cognitive and Affective Aspects. Data was collected through an online questionnaire distributed via Google Forms, targeting 126 Generation Z Shopee users in Jakarta. A quantitative approach was employed, utilizing descriptive analysis, simple tabulation, and mean score calculations. Findings reveal that Generation Z's impulsive buying level on Shopee is rated as "Agree" and "High." Most respondents fall into the Suggestion Impulse Buying and Planned Impulse Buying categories, with their impulsive purchasing behavior significantly influenced by Affective Aspects. These insights are valuable for Shopee, as they highlight opportunities for developing targeted marketing strategies that can stimulate impulsive buying behavior and ultimately boost sales within this demographic. Understanding these dynamics is crucial for businesses aiming to enhance their engagement with young consumers in the competitive online marketplace.

Distinct impulsivity profiles in subtypes of violence among community-dwelling patients with severe mental disorders: a longitudinal study

BackgroundAlthough only a few patients with severe mental disorders (SMD) can commit violent behaviour in the community, violent behaviour aggravates the stigma towards patients with SMD. Understanding the subtypes of violent behaviour may be beneficial for preventing violent behaviour among patients with SMD, but it has rarely been studied.MethodsThis longitudinal study investigated 1914 patients with SMD in the community at baseline, and the follow-up period ranged from February 2021 to August 2021. The Barratt Impulsiveness Scale Version-11, the Buss-Perry Aggression Questionnaire, the Impulsive/Premeditated Aggression Scale, the Personality Diagnostic Questionnaire and the MacArthur Community Violence Instrument were used at baseline. The Modified Overt Aggression Scale was used to assess the occurrence of violent behaviour (outcome) during the follow-up period. Cox regression models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Latent class analysis was used to characterise the subtypes of patients with SMD who engaged in violent behaviour at follow-up.ResultsWe found that 7.2% of patients with SMD presented violent behaviour within six months in the community. Younger age (OR = 0.98, 95% CI = 0.96-1.00, p = 0.016) and no economic source (OR = 1.60, 95% CI = 1.10–2.33, p = 0.014) were risk factors for violent behaviour. Patients with SMD who engaged in violent behaviour could be classified into three subtypes: one class characterised by a history of violence and impulsivity, another class characterised by high levels of aggression and motor impulsivity, and the last class characterised by median cognitive impulsivity.ConclusionsSocio-demographic factors were risk factors for violent behaviour among patients with SMD, which could eliminate the discrimination toward this group. Impulsivity played a vital role in identifying the three subtypes of patients with SMD who engaged in violent behaviour. These findings may be helpful for the development of a personalised violence risk management plan for patients with SMD who commit violent behaviour in the community.

The computational and neural substrates of individual differences in impulsivity under loss framework.

Numerous neuroimaging studies have identified significant individual variability in intertemporal choice, often attributed to three neural mechanisms: (1) increased reward circuit activity, (2) decreased cognitive control, and (3) prospection ability. These mechanisms that explain impulsivity, however, have been primarily studied in the gain domain. This study extends this investigation to the loss domain. We employed a hierarchical Bayesian drift-diffusion model (DDM) and the inter-subject representational similarity approach (IS-RSA) to investigate the potential computational neural substrates underlying impulsivity in loss domain across two experiments (n = 155). These experiments utilized a revised intertemporal task that independently manipulated the amounts of immediate and delayed-loss options. Behavioral results demonstrated positive correlations between the drift rate, measured by the DDM, and the impulsivity index K in Exp. 1 (n = 97) and were replicated in Exp. 2 (n = 58). Imaging analyses further revealed that the drift rate significantly mediated the relations between brain properties (e.g., prefrontal cortex activations and gray matter volume in the orbitofrontal cortex and precuneus) and K in Exp. 1. IS-RSA analyses indicated that variability in the drift rate also mediated the associations between inter-subject variations in activation patterns and individual differences in K. These findings suggest that individuals with similar impulsivity levels are likely to exhibit similar value processing patterns, providing a potential explanation for individual differences in impulsivity within a loss framework.

Statistical predictors of the co-occurrence between gambling disorder and problematic pornography use

Co-occurrence between gambling disorder (GD) and other mental disorders is common, but its association with problematic pornography use (PPU) remains unexplored. This study aimed to investigate relationships between sociodemographic variables, personality measures, psychopathology, emotional regulation, and impulsivity and the co-occurrence of GD and PPU using structural equation modeling (SEM). The sample consisted of 359 adults seeking treatment for GD. The short version of the Problematic Pornography Consumption Scale (PPCS-6) identified patients with GD + PPU. Psychopathology, impulsivity, emotional regulation, and personality were also assessed. Higher impulsivity levels statistically predicted co-occurrence between GD and PPU. Impulsivity mediated the relationship between younger age, maladaptive personality features, and emotional dysregulation and co-occurrence. Psychopathological distress did not directly associate with GD + PPU co-occurrence. Impulsivity relates importantly to the co-occurrence of GD and PPU. Younger age, maladaptive personality, and emotional dysregulation contribute to increased impulsivity levels and co-occurrence. The findings highlight the importance of addressing impulsivity in understanding and treating co-occurring GD and PPU.
