Analyzing early childhood allergy prevention motivation of mothers of infants and its predictors using latent class analysis and structural equation modelling

BackgroundAllergic diseases are among the most common chronic diseases in childhood. Early childhood allergy prevention (ECAP) behaviors of those caring for the infant during pregnancy and the first months of life may influence the risk of allergy development over the life course. Motivation and intention to use appropriate primary ECAP measures are thus of critical importance.AimsTo characterize parental ECAP motivation, (a) valid indicators will be developed and (b) typical parental characteristics will be identified. (c) According to socio-cognitive models, the predictive value of parental risk perception, control belief and self-efficacy for parental ECAP motivation shall be determined.MethodA sample of N = 343 (expectant) mothers of infants completed a questionnaire on self-reported ECAP motivation, risk perception, control belief, and self-efficacy. The cross-sectional data were analyzed using latent class analysis and structural equation modelling including nominal regression models.ResultsFour typical maternal response profiles (motivated to a customary degree, 70%; motivated to use primary preventive measures, 17.8%; reluctant towards new prevention measures, 6.4%; highly motivated to apply preventive measures in case of an existing allergy, 5.8%) could be identified for the items on ECAP motivation. After splitting the model variables “risk perception” (allergy vs. allergy-associated general health problems) and “self-efficacy” (trust vs. insecurity) a satisfactory model-fit was achieved (CFI = .939; RMSEA = .064). Particularly, increased “risk perception-allergy” (OR = 1.655) and “self-efficacy-insecurity” (OR = 2.013) as well as lower “risk perception-general health” (OR = 0.555) and “control belief” (OR = 0.217), respectively, are associated with higher ECAP motivation.ConclusionThe use of ECAP-measures by parents to protect their newborns from allergies is important, but there are deficiencies in their implementation. Based on a social cognitive model approach, predictive characteristics could be identified, which are associated with increased motivation to implement ECAP-measures. For public health our findings provide a promising basis for conception of behavioral and environmental ECAP prevention measures and their motivated implementation by parents.

Death of a Parent, Racial Inequities, and Cardiovascular Disease Risk in Early to Mid-adulthood.

Black Americans experience the death of a parent much earlier in the life course than White Americans on average. However, studies have not considered whether the cardiovascular health consequences of early parental death vary by race. Using data from the National Longitudinal Study of Adolescent to Adult Health, we explore associations between early parental death and cardiovascular disease (CVD) risk in early to mid-adulthood (N = 4,193). We find that the death of a parent during childhood or adolescence (ages 0-17) or the transition to adulthood (ages 18-27) is associated with increased CVD risk for Black Americans, whereas parental death following the transition to adulthood (ages 28+) undermines cardiovascular health for both Black Americans and White Americans. These findings illustrate how a stress and life course perspective can help inform strategies aimed at addressing both the unequal burden of bereavement and high cardiovascular risk faced by Black Americans.

Posttraumatic Stress Disorder in Children: A Narrative Review

Method: This narrative review summarizes research from the years 2019-2024 on posttraumatic stress disorder (PTSD) and posttraumatic stress symptoms (PTSS) in children. Results: This research suggests that prevalence rates have been highly variable as a function of the stress experienced, for example, post-surgery (15%), following exposure to war (28%) and following head injury (34%). The negative effects have included cognitive dysfunction, aggression and other behavioral difficulties and the comorbidities include sleep disorders, somatic symptoms and depression. Predictors/risk factors have been the primary focus in this literature and have included parent risk factors including exposure to intimate partner violence, sexual and emotional abuse. Sensory modulation and cognitive processes have been implicated as, for example, negative attention bias and subjective threat. Injuries and hospitalizations have been predictors as has been exposure to explosions and earthquakes. The most frequently studied intervention has been cognitive behavioral therapy which has consistently reduced the symptoms of PTSD. Potential underlying biological mechanisms have included parent PTSD, pregnancy inflammation, and autonomic dysregulation including low cortisol and heartrate, although reduced cortical thickness (volume) in several areas of the brain has been the most frequently studied potential mechanism. Discussion: The studies in this review highlight the prevalence and severity of posttraumatic stress disorder in children. However, they have been primarily based on mixed-age child and adolescent samples and the results have varied by the type of stress experienced and the severity of the stress.

Predicting Parental Post-Traumatic Stress Symptoms Following their Child's Stay in a Pediatric Intensive Care Unit, Prior to Discharge.

Objective: Develop an inpatient predictive model of parental post-traumatic stress (PTS) following their child's care in the Pediatric Intensive Care Unit (PICU). Design: Prospective observational cohort. Setting: Two tertiary care children's hospitals with mixed medical/surgical/cardiac PICUs. Subjects: Parents of patients admitted to the PICU. Interventions: None. Measurements and Main Results: Preadmission and admission data from 169 parents of 129 children who completed follow up screening for parental post-traumatic stress symptoms at 3-9 months post PICU discharge were utilized to develop a predictive model estimating the risk of parental PTS 3-9 months after hospital discharge. The parent cohort was predominantly female (63%), partnered (75%), and working (70%). Child median age was 3 years (IQR 0.36-9.04), and more than half had chronic illnesses (56%) or previous ICU admissions (64%). Thirty-five percent (60/169) of parents met criteria for PTS (>9 on the Post-traumatic Stress Disorder Symptom Scale-Interview). The machine learning model (XGBoost) predicted subjects with parental PTS with 76.7% accuracy, had a sensitivity of 0.83 (95% CI 0.586, 0.964), a specificity of 0.72 (95% CI 0.506, 0.879), a precision of 0.682 (95% CI 0.451, 0.861) and number needed to evaluate of 1.47 (95% CI 1.16, 1.98). The area under the receiver operating curve was 0.78 (95% CI 0.64, 0.92). The most important predictive pre-admission and admission variables were determined using the Local Interpretable Model-Agnostic Explanation, which identified seven variables used 100% of the time. Composite variables of parental history of mental illness and traumatic experiences were most important. Conclusion: A machine learning model using parent risk factors predicted subsequent PTS at 3-9 months following their child's PICU discharge with an accuracy of 76.7% and number needed to evaluate of 1.47. This performance is sufficient to identify parents who are at risk during hospitalization, making inpatient and acute post admission mitigation initiatives possible.

Differential Association of Preadolescent Risk Factors Across Developmental Patterns of Adolescent Concurrent Gambling Participation and Substance Use.

Early risk factors for gambling participation (GP) and substance use (SU) in adolescents have usually been studied separately, although these disorders were integrated into the same clinical category over a decade ago. This exploratory study aimed to investigate the early individual, parental, familial and social risk factors associated with developmental patterns of adolescent GP and SU in a population-representative cohort (N = 1594, 51.2% boys). Using a person-centered strategy and multiple assessments from age 12 to 17, six developmental patterns describing joint GP and SU courses were revealed. Non-substance users/non-gamblers served as the reference class in an integrated longitudinal-multivariate analysis framework examining 15 distinct risk factors. Results showed that a core of risk factors were common to all trajectory-classes of substance users with or without GP. For a similar level of SU, most of the risk factors associated with non-gambling users also affected their gambling peers. However, additional risk factors were specifically related to GP. Thus, substance users who also gamble were affected by a greater number of risk factors than non-gambling substance users. Findings are consistent with a developmental syndrome of addiction, which posits a shared etiology between different expressions of addiction as well as differences in risk factors that lead to distinct trajectories of addictive behaviors. They highlight the importance of considering both GP and SU for a comprehensive assessment of adolescents' level of risk with regard to addictive behaviors.

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.

Mentalized Affectivity, Helicopter Parenting, and Psychopathological Risk in Emerging Adults: A Network Analysis.

Emerging adulthood represents a critical stage characterized by heightened risks for anxiety, depression, and somatization symptoms development. Research has shown that difficulties in emotional identification, expression, and processing, as well as dysfunctional parenting styles, may exacerbate symptoms in emerging adults. The present study aimed at examining the interplay between mentalized affectivity (i.e., emotional identification, processing, and expression), helicopter parenting, and psychopathological risk in 913 Italian cisgender emerging adults (M = 24.34, SD = 2.81; 71.20% assigned female at birth), using network analysis. The results indicated moderate to strong associations between psychopathological symptoms, with emotional processing difficulties significantly associated with general anxiety, depression, and, to a lesser extent, somatization. Additionally, increased degrees of helicopter parenting from mothers were linked to increased psychopathology and higher emotional processing difficulties. These findings emphasize the importance of addressing the interconnection between symptoms and emotional processing to prevent and treat psychopathological risks in emerging adults. Moreover, interventions targeting intrusive and overprotecting parenting behaviors may promote well-being among emerging adults.

Cultivating parental virtuosi: therapeutic grammar and neuro-claims in Danish parenting courses

This article analyses how universal parenting courses for first-time parents in Danish municipalities represent measures to cultivate parents’ skills in ‘how to parent’. The aim of such courses is to support all new parents in the transition to parenthood, to teach parents about early child development, and to guide parents in managing their emotions. Drawing on ethnographic fieldwork and interviews, we address how the courses end up addressing a particular form of parenting (risk attuned, educated, science based) as well as a particular kind of parental self (reflective, responsible, sensible). We discuss how a therapeutic grammar imposes a new conformity on parents, and how neuro-claims form the basis for recommendations about child development and parent-child interactions. We also critically assess how mothers, in particular, are encouraged to work on and manage their maternal selves.

Protocol for a randomized controlled trial of an internet-based prevention intervention for young children at-risk for functional abdominal pain

BackgroundChronic pain often clusters in families, where parents and their offspring both experience chronic pain conditions. Young children of parents with irritable bowel syndrome (IBS) represent an at-risk group for the development of abdominal pain, disability, and excess health care visits in later childhood. Parental solicitous responses to children’s expressions of discomfort and maternal modeling of their own illness behavior contribute to a greater focus on somatic sensations, leading to illness behaviors in children. This randomized controlled trial will test the effectiveness of an early preventive web-based psychosocial intervention (REACH)[TM] vs. an educational web-based safety comparison condition delivered to parents with IBS to alter parental responses and lead to improved child health and decreased health care costs.MethodsParents with IBS who have children ages 4–7 years are recruited via community-based approaches (e.g., social media advertisements, school electronic distribution, research networks) and health care providers. The target sample is 460 parents randomized to REACH, a web-based social learning and cognitive behavior therapy (SLCBT) intervention or an educational web-based safety comparison condition (EC). Participants will be assessed at baseline, 6-week (immediate post-intervention), 6-month, 12-month, and 18-month follow-up periods (months post-completion of intervention). The primary outcome is change in parental solicitous/protective behaviors. Secondary outcomes include parent risk and protective factors, child health and symptom outcomes, and health care utilization and cost savings.DiscussionThis study adapts a validated, parent-delivered intervention to treat chronic pain in children to a web-based application designed to prevent the development of chronic pain in very young, high-risk children. If successful, this strategy can both prevent adverse sequelae of this condition from developing as well as be widely accessible. Furthermore, the availability of a prevention model for parent training could result in significant short- and long-term health benefits across a broad spectrum of conditions.Trial registrationClinicalTrials.gov NCT05730491.

Early Childhood Risk-Taking Behaviors in Chinese Parenting Environment: The Mediating Role of Parental Supervision

ABSTRACT Research Findings: Parental supervision, parental risk perception, and parental risk attitudes constitute an important parenting environment for the development of young children. To examine the mechanisms of Chinese parenting environment on young children’s risk-taking behaviors, this study first established a four-factor model and surveyed 497 parents of preschoolers. The results indicated that: (1) Chinese young children’s risk-taking was at moderately low level, and parental risk perceptions, parental attitudes and parental supervision were at moderately high level; (2) parental supervision completely mediated the relationship from parental risk perception to children’s risk-taking behavior (β = -0.139,95%CI [−0.267, −0.062], p < .001); (3) parental supervision partially mediated the relationship from parental risk attitudes to children’s risk-taking behavior (β = -0.068, 95%CI [−0.162, −0.027], p < .001); (4) this mediation model remained stable cross genders of children (∆χ 2 = 12.022, p = .799). Practice or Policy: The findings indicated that sufficient support and guidance for parenting should be provided to improve parental risk perceptions, attitudes and supervision which in turn create an environment safe and appropriate for risk-taking of Chinese young children.

Genetic and Clinical Factors Influencing Congenital Anomalies of the Kidney and Urinary Tract in Children: Insights from Prenatal and Postnatal Assessments.

Congenital anomalies of the kidney and urinary tract (CAKUT) significantly contribute to pediatric morbidity, often necessitating ureterorenal surgery. This study explored the relationship between genetic mutations, renal surgery requirements, and prenatal, postnatal, and parental risk factors in children with CAKUT. A retrospective analysis of 651 children diagnosed with CAKUT included patient demographics, parental risk factors, ultrasound findings, genetic mutations, and surgical incidence. Antenatal ultrasounds showed normal findings in 32.1%, hydronephrosis in 46.9%, and other abnormalities in 21% of cases. Surgical intervention correlated with higher hydronephrosis reduction than non-intervention. Genetic mutations were identified in 5.4% of cases, with 24.6% requiring surgery. Low neonatal birth weight (odds ratio [OR] = 0.98, p < 0.001), advanced maternal age (OR = 1.06, p < 0.001), and postnatal abnormal ultrasound findings (OR = 2.62, p < 0.001) were associated with increased genetic mutation risks. Antenatal hydronephrosis (OR = 3.85, p < 0.001) and postnatal urinary tract infections (OR = 4.85, p < 0.001) increased the likelihood of surgical intervention. Neonatal birth weight, maternal age, and postnatal ultrasound findings were identified as independent risk factors for genetic mutations, while no significant link was found between these genetic factors and the need for surgery. Surgical needs were associated with urinary tract infections and antenatal hydronephrosis, indicating that timely surgical intervention may benefit these patients.

Borderline personality disorder and parenting capacity: Understanding child protection population characteristics

Objective This paper describes an audit of borderline symptoms, risk factors for maltreatment and types of abuse among parents who completed a parenting capacity assessment at a South Australian health-based child protection service. Method A retrospective case note audit within a 28-month period was conducted and included parents ( n = 107) who had completed a Mclean’s screening instrument for borderline personality disorder and/or had a psychiatric review with a formal diagnosis. Parents who had a borderline personality disorder diagnosis or endorsed five or more symptoms were categorised into the ‘high’ borderline symptom group. Rates of parental risk factors for maltreatment and type of abuse were compared between parents with low or high borderline symptoms. Results Forty percent of parents endorsed at least five borderline symptoms on the screening tool. On average, parents high in borderline symptoms had a greater number of parental risk factors. Conclusions These findings highlight the importance of screening for personality pathology among parents presenting to child protection services. Foundational training for staff and making evidence-based interventions available should be considered in such settings.

Assessment of Parental Risk Factors Involved in Orofacial Clefts in Hail, Saudi Arabia: A Retrospective Cohort Study.

Background Orofacial clefts are congenital anomalies affecting the development of the oral and facial structures, influenced by genetic and environmental factors. The prevalence of orofacial clefts varies globally, necessitating region-specific studies to understand contributing factors.Orofacial clefts are among the most common congenital defects affecting the head and neck, underscoring the importance of investigating paternal and maternal influences on their development to enhance awareness and understanding of potential contributing factors.Therefore, this research aimed to investigate parental risk factors contributing to the development of orofacial clefts. Methods A retrospective cohort study was conducted at the Oral and Maxillofacial Department of King Khaled Hospital,Hail, Saudi Arabia, involving 40 parents of children born between 2019 and 2023 with orofacial clefts. Data collection included interviewer-administered questionnaires with parents addressing demographic information, pregnancy details, parental medical history, and postoperative outcomes. Statistical analysis utilized descriptive statistics, chi-square tests, Fisher's exact test, and linear regression, with significance defined as p<0.05. Results The study had a gender distribution of 19 males (47.5%) and 21 females (52.5%) among orofacial cleft cases (p<0.75), with cleft palate (13 cases, 32.5%) and cleft lip (11 cases, 27.5%) being the most prevalent anomalies (p<0.05). Maternal supplementation rates were high, with 34 mothers (85%, p<0.05) taking folic acid and 36 mothers (90%, p<0.05) taking iron, yet orofacial clefts incidence persisted. Paternal risk factors such as tobacco use were reported by 19 fathers (47.5%, p<0.05), and familial history of orofacial clefts was noted in nine cases (22.5%, p<0.05). Postoperative outcomes indicated varying levels of functional recovery and satisfaction. Conclusion This study explored the complex origins of orofacial clefts, emphasizing genetic and environmental influences. The findings suggest a potential paternal risk factor. The study highlights the need for further investigation into genetic mechanisms and the development of effective prevention strategies.

Parental incarceration and health risks in a population-based study of U.S. early adolescents: Results among racialized groups

Parental incarceration is an adverse childhood experience that inequitably burdens families of color and affects millions of U.S. children and adolescents. Although racialized disparities in exposure to parental incarceration are often acknowledged, researchers have yet to examine whether manifestations of racism may affect the link between parental incarceration and youth outcomes. This study provides a first look at how parental incarceration relates to health vulnerabilities in the Adolescent Brain Cognitive Development (ABCD) study, an ongoing, population-based study of U.S. children born between 2006 and 2008. We start by describing exposure to parental incarceration and then examine how parental incarceration, state-level racial prejudice, and discrimination relate to health risks among 9191 White (66%), Black (19%), or Hispanic (15%) youth. Consistent with what we know about pervasive racialized disparities in the U.S. criminal legal system, we find that 19.3% of Black children in our sample have experienced parental incarceration, followed by 7.8% of Hispanic children, and 4.8% of White children. Results of multilevel mixed models further indicate that parental incarceration was associated with increased health risks among White children whereas family economic hardship and discrimination experiences were more robustly associated with health vulnerabilities among Black and Hispanic children. Additional analyses explored whether parental incarceration was associated with other outcomes among Black and Hispanic children, revealing increased risk for behavior problems contingent upon parental incarceration and discrimination for Black children and Hispanic boys. Among Hispanic girls, parental incarceration was associated with increased risk of behavior problems in states with higher levels of racism. Results suggest that parental incarceration contributes to risk among early adolescents across racialized groups, but that the specific toll it takes depends on outcomes assessed and the context in which it occurs.

Paediatric Post-Traumatic Stress Risk for Young People and Parents following Acute Admission for Paediatric Multisystem Inflammatory Syndrome: Retrospective Analysis of Psychological Screening and Support.

Paediatric Multisystem Inflammatory Syndrome (PIMS-TS) is a novel condition that was identified for the first time during the COVID-19 pandemic. Limited research exists that describes the psychological needs of children and young people (CYP) following an acute hospital admission for PIMS-TS. A retrospective cohort study was conducted to explore both psychological need and access to psychology services for CYP and their families who were admitted to a paediatric tertiary hospital in London, UK, for PIMS-TS between April 2020 and May 2021. We included 121 CYP and a parent/caregiver for each. In total, 23.3% of the CYP were at risk of developing a traumatic stress response and 11.6% were at risk of experiencing emotional disturbance. Of the parents screened, 40.5% also scored above clinical cut-off for a trauma response. There was a significant relationship observed between CYP and parents identified as having a trauma risk. The importance of proactive screening for both trauma and emotional distress in CYP and their parents/caregivers following acute hospital admission is highlighted. In addition, there is a need to think about a CYP as part of a system of care and to ensure that clinicians pay attention to parental wellbeing and mental health when understanding the psychological impact on a child.

Exploring Parental Attitudes and Perceptions Regarding Childhood Vaccinations in Greece: A Study Within the Framework of the National Health Examination Survey (EMENO).

Vaccinations have reduced illnesses and mortality rates globally, yet negative attitudes and uncertainty about them hinder their acceptability and efficacy. The study aims to document Greek parents' immunization perceptions and risk factors. Spanning 2014-2017, 447 parents (68% mothers) who participated in the Greek Health Examination Survey EMENO (National Survey of Morbidity and Risk Factors) completed an interview-delivered questionnaire. Attitudes were categorized into three groups: absolutely positive, positive, and negative. Absolutely positive attitudes included positive responses to all five statements in favor of vaccination and negative responses to the two statements against vaccination. Negative attitudes included positive responses to either one or both statements against vaccination and negative responses to all five statements in favor of vaccination.. All other participants were categorized as having a positive attitude. Skepticism towards vaccinations was classified into skeptical and non-skeptical groups based on responses to five statements implying uncertainty or skepticism. Participants were considered skeptical if they provided positive responses to at least three of these statements, and non-skeptical if they had none or up to two positive responses.The statistical analysis accounted for the study design whereas inverse probability weighting was used to adjust for non-response and multiple imputations were employed to impute missing values. The components of parental attitude and vaccine skepticism were identified using weighted multinomial logistic regression and logistic regression, respectively. In total, 16.6% were classified as having absolutely positive attitudes towards vaccinations whereas 42.1% were skeptical of vaccines. Of all participants, 96.0% agreed that vaccinations are essential for their child's well-being and adhere to scientific recommendations. However, concerns were also mentioned, with 26.2% worrying about potential adverse effects, and 21.6% believing it is better to acquire immunity through illness rather than vaccination. Positive participants, compared to absolutely positive ones, were more likely to be of Greek origin (adjusted relative rate ratio (aRRR): 3.35; 95% CI: 1.53-7.30) and living in semi-urban areas (aRRR: 4.84; 95% CI: 1.77-13.29). Negative participants, in contrast, were more likely to have higher education (aRRR: 2.98; 95% CI: 1.05-8.44) but also to live in semi-urban areas (aRRR: 6.43; 95% CI: 1.69-24.56). Furthermore, parents of Greek origin had significantly higher odds of being skeptical towards vaccination (adjusted Odds Ratio (aOR): 2.86; 95% CI: 1.36-5.98), while married or cohabiting parents had lower odds of being skeptical compared to single parents (aOR: 0.60; 95% CI: 0.35-1.06). While parents in this study recognize the importance of childhood immunizations, there is a widespread presence of negative attitudes and skepticism that can have a detrimental impact on vaccination rates.

The role of threat sensitivity, social affiliation, and left-behind experience in shaping adolescent callous-unemotional and borderline personality traits

Exploring callous-unemotional (CU) and borderline personality disorder (BPD) traits during adolescence is crucial due to its role in the emergence of personality pathologies. Recent research highlights threat sensitivity and social affiliation as fundamental factors in the etiology of broader interpersonal dysfunctions in personality disorders. Further studies are needed to explore the contributions of these factors to CU and BPD traits, while considering specific parental risk factors within distinct cultural contexts. This study examines the effects of threat sensitivity, social affiliation, and left-behind experience (LBE) on CU and BPD traits in 563 Chinese adolescents. We found that the interaction between threat sensitivity and social affiliation significantly predicts CU traits in adolescents without LBE, where reduced social affiliation amplifies the association between low threat sensitivity and CU traits. Conversely, LBE and a strong need for social affiliation intensify the association between increased threat sensitivity and BPD traits. These findings highlight the specific contributions of dispositional factors to CU and BPD traits, offering insights into their divergent pathways. By elucidating the nuanced interplay of dispositional and parental risk factors, this study enhances our understanding of the predictors of adolescent personality disorders and emphasizes the need for targeted interventions tailored to these dynamics.
