“I get the referral because nobody else wants to work with this person”: A critical realist analysis of social workers providing care to people living with borderline personality disorder

Borderline personality disorder (BPD) is a mental health condition characterized by unstable relationships, self-image, and emotions, as well as impulsive behaviors and high rates of morbidity and mortality. Provider-based stigmatization of individuals with BPD is associated with poor health outcomes and increased mortality risk. However, little is known about social workers' experiences in providing care to people living with BPD (PLBPD). This study explored social workers' perspectives on the impact of stigma on care for PLBPD. Between April 2020 and January 2021, qualitative semi-structured interviews were conducted with 41 social workers practicing across the continuum of care (e.g., community services and hospitals) in Ontario, Canada. Data were analyzed using Critical Realist Analysis. Four primary themes emerged: (1) stigmatization of PLBPD due to the complexity of their needs (e.g., avoidance, blame, name-calling by providers); (2) lack of BPD-specific training and education in social work curricula; (3) observed stigmatization of PLBPD by social workers and other professionals (e.g., psychologists and physicians); and (4) suggestions for improving care experiences for PLBPD. Results suggest that provider-based stigma remains a significant quality of care issue affecting PLBPD. Further research is needed to understand the scope of these issues among diverse PLBPD populations, within social work practice, and across interprofessional care settings.

Delay of Gratification in Preschoolers with Autism and Concerns for ADHD.

Self-regulation abilities in childhood are predictive of a range of challenges later in life, making it important to identify difficulties in this area as early as possible. Autistic children and those with attention-deficit/hyperactivity disorder (ADHD) often have difficulties with self-regulation, but little is known about the similarities and differences in such abilities across neurodevelopmental conditions. We examined self-regulation using a delay of gratification task in 36-month-old autistic children (n = 20), those showing clinically relevant concerns for ADHD (i.e. ADHD Concerns; n = 24), and Comparison children without these conditions (n = 130); early predictors of self-regulation were also assessed. Both the Autism and ADHD Concerns groups had greater difficulty waiting for a desired snack than the Comparison group. At the longest delay trial (30 seconds), a substantial percentage of autistic children (50%) and those with ADHD Concerns (35%) consumed the snack prematurely, in contrast to only 16% of the Comparison group. Parent-reported temperament-based impulsivity at 18 months and examiner-observed ADHD-like traits at 24 months were associated with increased self-regulation challenges at 36 months, regardless of group. Adjusting for verbal abilities attenuated some of these differences and associations, suggesting that language may be an important mechanism undergirding early self-regulatory abilities. Given possible links between preschool self-regulation and a range of critical functional outcomes, future studies may explore the efficacy of early interventions targeting impulsivity and regulatory behaviors in infants and toddlers at elevated likelihood for developing self-regulation challenges to potentially reduce the impact of these difficulties later in life.

Loss of Control Eating in Adults With Impulsive and/or Inattentive Tendencies.

Previous research has tended to consider impulsive, inattentive, and loss of control eating (LOC) tendencies as symptoms of greater pathologies in treatment-seeking samples. However, inattentive and impulsive tendencies and LOC often co-occur. Although LOC is an important diagnostic component of disordered eating (ED), it has recently been argued to be a dysregulated eating behavior in its own right. The purpose of the current self-report study was, therefore, to investigate the association between impulsive and inattentive tendencies and LOC in adults after accounting for ED. A community sample of 516 adults was surveyed online about their inattentive and impulsive tendencies, LOC, and ED behaviors. A hierarchical multiple linear regression revealed ED, inattentive, and impulsive symptoms to be independent, significant, positive predictors of LOC. These findings suggest that the levels of inattentive and, to a lesser extent, impulsive tendencies are significantly associated with LOC in adults, even after ED is accounted for. Moreover, inattentive tendencies were found to be more significantly associated with LOC than impulsive tendencies. These are novel and important findings that can be used to inform both clinicians and individuals with inattentive and impulsive tendencies alike of this association. Considering the well-documented adverse health and wellbeing outcomes associated with LOC, future feasibility trials are needed aimed at treating this co-occurrence.

Adaptive changes in multiple aspects of emotion regulation in the offspring of pregnant persons receiving a diet-and-exercise intervention relative to usual pregnancy care: A randomized controlled trial

BackgroundHuman studies examining the influence of prenatal diet and/or exercise interventions on offspring neurodevelopment are mixed. Interventions that include the provision of whole foods, nutritional counselling, address exercise behaviors, and that utilize multimethod assessments of offspring emotion regulation may better reveal the impact of these interventions on neurodevelopment. ObjectiveTo explore whether the Be Healthy in Pregnancy (BHIP) prenatal diet-and-exercise intervention improves emotion regulation (ER) in 22-month-old offspring. MethodsPregnant persons (>18 years, singleton pregnancy) were recruited between 12-17 weeks gestation and randomized to the intervention [high protein energy-controlled diet via the provision of cottage cheese, Greek yogurt, low-fat milk, individualized biweekly nutritional counselling, a controlled walking program, and usual pregnancy care (UPC)] or control (UPC alone) groups. ER in offspring (mage=22.2(SD=4.04); 50.9% female; intervention: n=29, control: n=28) was assessed using reports from pregnant persons and their partners on the Child Behavior Checklist, and the Behavior Rating Inventory of Executive Function-Preschool Version, laboratory observational tasks examining inhibitory control, attention, and empathy, and high frequency heart rate variability (HF-HRV). ResultsChildren exposed to the BHIP intervention exhibited medium to large effect size reductions in pregnant person and partner reported externalizing (effect size ƞ2pmother=0.08, 95% CI of the difference[0.05,7.14]; ƞ2ppartner=0.17[1.68,9.65]), internalizing ƞ2pmother=0.08[0.09,5.32]; ƞ2ppartner=0.13[0.84,8.88]) and total behavior problems ƞ2pmother=0.09[0.72,11.87];; ƞ2ppartner=0.17 [3.17,17.88]) relative to control participants’ children. Pregnant persons, but not partners, reported fewer problems with inhibitory control (ƞ2p=0.13[1.40,8.55]), cognitive flexibility (ƞ2p=0.08[0.18,4.85]), emergent metacognition (ƞ2p=0.14[2.00,11.59]), and global executive function (ƞ2p=0.14[3.37,20.12]). Intervention children displayed fewer impulsive behaviors (ƞ2p=0.11[0.16,1.77]) and a longer attention span (ƞ2p=0.08[0.30,13.34]). Finally, intervention children exhibited greater baseline HF-HRV (ƞ2p=0.10[0.16,2.01]), and adaptive HF-HRV reactivity during the impulsivity (ƞ2p=0.12[0.20,2.19]) and attention tasks (ƞ2p=0.21[0.74,2.77]). ConclusionsThis intervention was associated with medium/large effect size improvements in offspring ER. Larger trials are needed to confirm the potential of these interventions on offspring neurodevelopment. Clinical Trial RegistryNCT01689961, Sept 21, 2012

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.

How False Advertising Victims’ Experiences Define Their Online Purchase Decision in Fashion Product? - Comparison between Generations

This research aimed to analyze how the experiences of victims of false advertising in the fashion industry can influence their behavior in online purchasing decisions. This research used quantitative research, which is based on the positivism paradigm. Research data was obtained from consumers in the fashion industry in Indonesia who had experienced advertising fraud, with a sample size of 200 respondents. Research data was then analyzed using Partial Least Square-Structural Equation Modeling (PLS-SEM) with a moderation model. This research also compared the purchasing decision behavior of each generation as control variables. The results of the analysis showed that: exposure to false advertising and perceived risk do not have a significant influence on purchasingdecisions, both in model one and model two, hedonism and impulsive buying behavior have a significant influence on purchase decision, both in model one and two, hedonism and impulsive buying behavior are neither able to strengthen nor weaken the influence of exposure to false advertising and perceived risk on purchase decision, both models and all control variables consisting of age generation, gender and marital status do not havea significant influence on purchase decision.

Beyond the Off-Label: A Systematic Review of What We Know About Clozapine Use for Children.

Introduction: It is essential not to delay behavior management and control for aggression, violence, and impulsive behavior in young people. Clozapine has been widely used in adolescents and adults to manage violence and aggression in Schizophrenia. However, there are limited data on the use of clozapine in children, and no systematic review has addressed its use in this population. Objective and Methods: To better understand the conditions under which clozapine is used as a therapeutic alternative for nonschizophrenic diagnoses and to assess the current evidence supporting its prescription to children, a systematic review was conducted. The review followed PRISMA guidelines and was registered in PROSPERO under the ID CRD42024537707. Results: The review identified that all the studies used clozapine to address externalizing behavior, particularly aggressive behavior, and found positive outcomes supporting its use for treating children with treatment-resistant aggression. The studies also found that clozapine was well-tolerated in all cases. However, the studies were limited and mainly consisted of open trials without a control group. Conclusion: Further high-quality research is needed to establish precise guidelines for using clozapine in children.

Treatments with versus without medication for children with behavioural difficulties in clinical practice: an economic evaluation with observational data.

Economic evaluations of treatments for children with behavioural difficulties (i.e., characteristics of attention-deficit/hyperactivity disorder (ADHD) and/or oppositional defiant disorder (ODD)) usually rely on data of randomised controlled trials or are model-based. Findings of such studies may not be representative of cost-effectiveness and cost-utility in clinical practice. The current longitudinal study aimed to perform an economic evaluation of treatments for children with hyperactivity, impulsive behaviours, inattention, and/or behavioural difficulties using observational data that were obtained in clinical practice. Parents of 209 children (aged 5-12) who were referred to 1 of 10 Dutch youth mental healthcare institutions and who received treatment with (n = 108) or without (n = 101) the use of medication, filled out questionnaires at three timepoints (baseline, and ~ 6 and ~12 months later). Propensity score matching was used to make both groups comparable. Outcomes included quality-adjusted life years (QALYs), ADHD and ODD symptom severity, and impairment. Costs were measured from a societal perspective. Incremental cost-effectiveness ratios (ICERs) were estimated, and cost-effectiveness acceptability curves (CEACs) were derived to show uncertainty around the ICER. Results did not show statistically significant differences in costs and effects between children who were treated with medication (alone or in combination with non-medication treatment) and those who were treated without medication. CEAC suggested that medication treatment has a 55% probability of being cost-effective at the €80,000 threshold and 36% at the €20,000 threshold compared with treatment without medication. Using observational data, our study did not provide clear evidence of the cost-effectiveness and cost-utility of treatment with medication compared with treatment without medication in clinical practice.

Cyberbullying and Internet Gaming Disorders in Pakistan: Strategies for Mitigation

Dear Editor,Cyberbullying and internet gaming disorders (IGDs) have emerged as significant concerns in Pakistan, particularly among adolescents. This editorial explores the prevalence, impacts, and potential interventions for these issues, drawing on recentresearch and literature. The need for a multifaceted approach involving parents, educators, communities, and government is emphasized to protect vulnerable populations and promote a healthier digital environment. The advent of widespread internet access in Pakistan has brought numerous benefits, yet it has also introduced challenges such as cyberbullying andinternet gaming disorders (IGDs). These phenomena have serious implications for the mental health and well-being of adolescents. Given the relative novelty of these issues in the local context and the paucity of research, it is crucial to develop a comprehensive understanding and effective strategies for mitigation. According to a met analysis of earlier research, Asianyouth have a high IGD prevalence 1 Defining Cyberbullying and IGDs Cyberbullying lacks a universally accepted definitiondue to its complexity. Alipan and Skues provide a useful framework, describing it as behavior that intentionally harms victims using information and communication technology, perceived as harmful by victims, and witnessed by bystanders as negative2 . IGDs are recognized in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a condition warranting further study. Vulnerability of Adolescents Adolescents are particularly susceptible to cyberbullying and IGDs due to the developmental changes they experience. The American Academy of Pediatrics recommends against providing personal mobile phones to children under 13 years old, highlighting their vulnerability to risky behaviors3. The prefrontal cortex, responsible for decision making and impulse control, is not fully developed in adolescents, making them prone to impulsive and risky behaviors, including cyberbullying and excessive gaming.

Relationship between Social Media Addiction and Urgency in Young Adults

This study intended to inspect the relationship of urgency (positive and negative) and social media addiction (SMA) in young adults. The study also explored the gender differences on SMA and urgency. Two of the proposed hypotheses were put into testing, i.e., i) There is a relationship between SMA and urgency among young adults, and ii) There are gender differences in SMA and urgency. This research used a correlational research design and convenience sampling strategy. A sample of 300 university students was collected that included 150 males and 150 females age ranging between 18-25 years (M= 19.03, SD= 3.29). The data was collected in person through a self-constructed demographic questionnaire, Social Networking Addiction Scale (SNAS), and Urgency, Premeditation, Perseverance, Sensation Seeking, and Positive Urgency (UPPS-P) Impulsive Behavior Scale. The data was analyzed through SPSS software and Pearson correlation along with independent sample t-test were employed to test the hypotheses. The findings revealed that there is a positive relationship between urgency and SMA among young adults, however, no significant gender differences were found in urgency, social media addiction, and their subscales. This study urges young adults to limit social media use to prevent psychological dependence that can harm both productivity and mental well-being. It highlights the tendency of individuals to turn to social media as an escape when overwhelmed by emotional states, often sharing more than they would in a more balanced state of mind. This emotional oversharing can lead to unintended consequences, impacting personal and professional lives.

UNDERSTANDING THE ROLE OF FOMO (FEAR OF MISSING OUT) IN IMPULSE PURCHASE FOR SMES

This study examines the influence of price discounts on impulse buying through live streaming among e-commerce users in Indonesia. The research adopts a quantitative approach, utilizing a survey methodology with questionnaires distributed to a purposive sample of 152 consumers from the Dolee Branded Store. Data were analyzed using SmartPLS 4.0 software, employing the PLS-SEM analysis method. The findings reveal that price discounts significantly directly impact impulse buying behavior. Furthermore, price discounts also significantly affect live streaming, which, in turn, substantially influences impulse buying. The results indicate that live streaming acts as a mediating variable, enhancing the effect of price discounts on impulse purchases. This study underscores the importance of integrating price discount strategies with live streaming to drive impulse buying behavior in the e-commerce sector effectively. By leveraging live streaming as a promotional tool, businesses can maximize the impact of their discount offers, leading to increased consumer engagement and sales. These insights provide valuable implications for marketers and e-commerce platforms aiming to enhance their promotional effectiveness and customer acquisition strategies.

Exploring Emotion Control and Alexithymia in Autistic Adults: An Ecological Momentary Assessment Study.

Difficulties in controlling emotions - a proxy for emotion dysregulation (ED)-and difficulties in expressing feelings in words-'absence of emotion labelling' or alexithymia-co-exist in autism and contribute to elevated levels of impulsive and suicidal behaviour. To date, studies linking the two phenomena have relied on retrospective self-reported measures, lacking support for generalizability to real-life situations. The present study investigated in vivo emotion labelling and its impact on emotion control in 29 autistic adults without intellectual disability (ASC) and 28 neurotypical (NT) individuals of similar age, sex, and educational level. Participants were trained in an Ecological Momentary Assessment (EMA) to label their emotions, the arousal dimension, and their emotion control via smartphone over a one-week period. Findings showed that the ASC group experienced more instances of 'having an emotion that I cannot name' and, when they were able to label their emotions, they reported higher rates of negative and conflicting (simultaneously positive and negative) emotions. In both groups, the absence of emotion labelling, and intense negative emotions were associated with impaired emotion control. However, the association between lack of emotional awareness-'I have no emotion'-and impaired emotion control was only evident in ASC individuals. Our study highlights a nuanced facet of emotional processing in the ASC population. Further research is needed to gain a deeper understanding of the complex relationship between ED and alexithymia in autism.

The Cumulative Impact of Recurrent Experiences of Intimate Partner Violence on Emotion Dysregulation: A Longitudinal Investigation.

Intimate partner violence (IPV) disproportionately affects women and has been linked to a range of negative psychological outcomes, including emotion dysregulation. Although IPV is often recurrent and tends to escalate in severity over time, few studies have examined the potential effects of recurrent experiences of IPV on emotion dysregulation. The current study employed a longitudinal design to examine the cumulative impact of recurrent experiences of IPV on emotion dysregulation. Participants were 491 young adult community women (Mage = 21.74; 61.3% White, 35% African American/Black) who completed self-report measures of IPV and emotion dysregulation every 4 months for 28 months. Multilevel structural equation modeling techniques revealed that, at the within-person level, increases in cumulative IPV were associated with increases in global emotion dysregulation across the 28 months. In particular, the accumulation of IPV experiences over time was associated with increases in difficulties controlling impulsive behaviors when distressed and accessing effective emotion regulation strategies. At the between-person level, greater average cumulative IPV was associated with greater mean levels of global emotion dysregulation, as well as four specific dimensions of emotion dysregulation, including difficulties accepting emotional responses, accessing effective emotion regulation strategies, and both engaging in goal-directed behaviors and controlling impulsive behaviors when distressed. These findings suggest the potential cumulative impact of IPV on both global and more specific dimensions of emotion dysregulation. Results also highlight emotion dysregulation as a potentially important construct to assess and target in interventions for women experiencing recurrent IPV.

The result shows the variable that influences impulsive buying behavior of Jambi province buyers is arousal. SMEs in Jambi can develop more strategies to encourage the arousal of online customer such creating a periodical sales discount with the aim of the program to gain impulsive buying behavior from customer arousal and increasing sales from that behavior.

Persuasi Rute Periferal Exo Sebagai Brand Ambassador Scarlett Whitening Terhadap Impulsive Buying

The popularity of K-Wave amongst Indonesian creates a competition for brands, resulting them competing to use Korean artists as brand ambassadors. This practice is widely adopted in business, particularly in the beauty industry, which is rapidly growing in Indonesia. This research aims to determine the effect of EXO's peripheral route persuasion as the brand ambassador of Scarlett Whitening on impulsive buying behavior. The study uses a quantitative approach to provide detailed statistical analysis on the influence of brand ambassadors on consumer impulsive buying. Data collected through an online questionnaire, distributed to 385 respondents who met the requirements of sample criteria. The results of the study indicate a significant positive influence of peripheral route persuasion on impulsive buying behavior. This means that the presence of EXO as a brand ambassador is effective in delivering marketing messages through the peripheral route, which includes elements such as likability and attractiveness, driving consumers to make impulsive purchases.

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.

Evaluation of Recovery Rate in Poison Patients with or Without Standard Antidote Treatment

Aim: To evaluate the recovery rate of poisoning with regards to the availability and administration of standard antidote. Introduction: Poison consumption is one of the most common causes of death across the world. The reason is its easy availability and impulsive behaviour associated with suicidal thoughts. Antidotes are the agents which counteract the harmful effects of poison. Poisoning can be treated with antidotes but not all poisons have antidotes, this study helps to analyze the effectiveness of antidotes in early recovery from poisoning accompanied by stabilization techniques implemented. Methodology: A prospective observational study was conducted in the inpatient department of General Medicine, Gandhi Hospital, Secunderabad from October 2021 to March 2022. Results: Poison consumption was more predominant among males, and young adults are the most affected age group. Suicide was identified as the primary reason for poison intake, while accidental poison ingestion was mostly seen in children. Pesticides were the most commonly consumed poisons. The antidote was administered in approximately 33% of cases, while it was not provided in 15%. For the remaining cases, an antidote was not available. The overall recovery rate was 77%, with females showing higher recovery rates than males. Adolescents had the highest recovery rate, followed by middle-aged adults. Conclusion: Our study concludes that the recovery was rapid in cases where a standard antidote was available and administered. Performing decontamination techniques within a few hours of poison consumption was also efficient.

The Influence of Discount Cuts and Buzz Marketing Strategies on Live Sales Through E-commerce on Impulsive Buying Behavior

The level of internet usage in Indonesia is considered very high, encouraging the community to continuously adapt to using technology as a medium for business creation. The utilization of technology in the business field requires business actors to enhance creativity and strategies to influence and attract consumer purchasing interest. This research will explain the influence of discounts and buzz marketing strategies on live sales through e-commerce on impulsive buying behavior, with respondents aged 15-29 who reside in Jakarta. The technique used in the research for sample selection is non-probability sampling with purposive sampling. Data collection in this research was conducted by distributing questionnaires. The research analysis technique used is Smart PLS. Ultimately, the results of this study show that discounts on live sales through e-commerce have a positive but insignificant effect on impulsive buying behavior. Meanwhile, buzz marketing in live sales through e-commerce has a significant positive effect on impulsive buying behavior.

Serotonin drives aggression and social behaviors of laboratory male mice in a semi-natural environment.

Aggression is an adaptive social behavior crucial for the stability and prosperity of social groups. When uncontrolled, aggression leads to pathological violence that disrupts group structure and individual wellbeing. The comorbidity of uncontrolled aggression across different psychopathologies makes it a potential endophenotype of mental disorders with the same neurobiological substrates. Serotonin plays a critical role in regulating impulsive and aggressive behaviors. Mice lacking in brain serotonin, due to the ablation of tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme in serotonin synthesis, could serve as a potential model for studying pathological aggression. Home cage monitoring allows for the continuous observation and quantification of social and non-social behaviors in group-housed, freely-moving mice. Using an ethological approach, we investigated the impact of central serotonin ablation on the everyday expression of social and non-social behaviors and their correlations in undisturbed, group-living Tph2-deficient and wildtype mice. By training a machine learning algorithm on behavioral time series, "allogrooming", "struggling at feeder", and "eating" emerged as key behaviors dissociating one genotype from the other. Although Tph2-deficient mice exhibited characteristics of pathological aggression and reduced communication compared to wildtype animals, they still demonstrated affiliative huddle behaviors to normal levels. Altogether, such a distinct and dynamic phenotype of Tph2-deficient mice influenced the group's structure and the subsequent development of its hierarchical organization. These aspects were analyzed using social network analysis and the Glicko rating methods. This study demonstrates the importance of the ethological approach for understanding the global impact of pathological aggression on various aspects of life, both at the individual and group levels. Home cage monitoring allows the observation of the natural behaviors of mice in a semi-natural habitat, providing an accurate representation of real-world phenomena and pathological mechanisms. The results of this study provide insights into the neurobiological substrate of pathological aggression and its potential role in complex brain disorders.
