Prospective associations of prenatal stress with child behavior: Moderation by the early childhood caregiving environment.

Fetal exposure to prenatal stress can increase risk for psychopathology but postnatal caregiving may offset risk. This study tests whether maternal sensitivity and the home environment during early childhood modify associations of prenatal stress with offspring behavior in a sample of 127 mother-child pairs (n = 127). Mothers reported on perceived stress during pregnancy. Maternal sensitivity was rated by coders during a parent-child free play task when children were 4 years old. One year later, mothers reported on the home environment, child internalizing and externalizing behaviors, and children completed an assessment of inhibitory control. As hypothesized, the early childhood caregiving environment modified associations of prenatal stress with child behavior. Specifically, prenatal stress was associated with more internalizing behaviors at lower levels of maternal sensitivity and in home environments that were lower in emotional support and cognitive stimulation, but not at mean or higher levels. Furthermore, prenatal stress was associated with lower inhibitory control only at lower levels of maternal sensitivity, but not at higher levels. Maternal sensitivity and an emotionally supportive and cognitively stimulating home environment in early childhood may be important factors that mitigate risk for mental health problems among children exposed to prenatal stress.

Trajectories of risk and resilience: The role of empathy and perceived social support in the context of early adversity

BackgroundEvidence overwhelmingly suggests that adverse childhood experiences (ACEs) is a risk factor for poor mental health outcomes. However, the specific mechanisms via which ACEs confer an increased risk of psychopathology are less well understood. ObjectiveThe study modelled the effect of empathy and perceived social support (PSS) on mental health outcomes in a mixed clinical and non-clinical population, within the context of exposure to ACEs. Participants and settingA total of 575 participants (comprising a treatment-receiving and community-based sample), aged 18 to 65 completed self-report measures assessing early adversity, PSS, empathy, and mental health outcomes. MethodsMultiple mediation analyses were used to investigate whether empathy and PSS mediated the relationship between self-reported ACEs and mental health outcomes, and whether affective and cognitive empathy affected differentially the link between emotional neglect and psychological distress. ResultsResults revealed a statistically significant indirect effect of ACEs on adult mental health through affective empathy and PSS. Emotional neglect was the only type of adversity significantly correlated with both dimensions of empathy. The indirect effect of emotional neglect on mental health outcomes via cognitive and affective empathy was also statistically significant. ConclusionsStudy results highlight the role of affective empathy and PSS as transdiagnostic mechanisms influencing the pathway between early adversity and adult mental health, and the importance of taking these into account when designing interventions aiming to promote well-being among those who have experienced childhood adversity.

Body image concerns among individuals with different levels of sporting engagement and exercise: A longitudinal study

This longitudinal study examined whether body image concerns (general; sporting) predicted eating disorder psychopathology, and whether the link differed according to nature of sport engagement. Participants were competitive sports engagers, non-competitive sports engagers, or sports non-engagers. At baseline, 510 adults completed online measures of sports demographics, eating psychopathology and body image. Eating psychopathology and body image measures were taken at follow-up (6 months later). Competitive sports engagers had better body image than the other two groups. Poorer body appreciation and better appearance-related body image predicted higher eating disorder psychopathology. Engaging in sports competitively may be beneficial for body image. However, positive appearance-related sporting body image may pose a risk for later eating psychopathology.

Influence of early childhood parental hostility and socioeconomic stress on children's internalizing symptom trajectories from childhood to adolescence.

Children and adolescents with elevated internalizing symptoms are at increased risk for depression, anxiety, and other psychopathology later in life. The present study examined the predictive links between two bioecological factors in early childhood-parental hostility and socioeconomic stress-and children's internalizing symptom class outcomes, while considering the effects of child sex assigned at birth on internalizing symptom development from childhood to adolescence. The study used a sample of 1,534 children to test the predictive effects of socioeconomic stress at ages 18 and 27 months; hostile parenting measured at child ages 4-5; and sex assigned at birth on children's internalizing symptom latent class outcomes at child ages 7-9, 10-12, 13-15, and 16-19. Analyses also tested the mediating effect of parenting on the relationship between socioeconomic stress and children's symptom classes. Other covariates included parent depressive symptoms at child ages 4-5 and child race and ethnicity. Analyses identified three distinct heterogenous internalizing symptom classes characterized by relative symptom levels and progression: low (35%); moderate and increasing (41%); and higher and increasing (24%). As anticipated, higher levels of parental hostility in early childhood predicted membership in the higher and increasing symptom class, compared with the low symptom class (odds ratio (OR) = .61, 95% confidence interval (CI) [.48,.77]). Higher levels of early childhood socioeconomic stress were also associated with the likelihood of belonging to the higher-increasing symptom class compared to the low and moderate-increasing classes (OR = .46, 95% CI [.35,.60] and OR = .56, 95% CI [.44,.72], respectively). The total (c = .61) and direct (c' = .57) effects of socioeconomic stress on children's symptom class membership in the mediation analysis were significant (p <.001). Study findings suggest that intervening on modifiable bioecological stressors-including parenting behaviors and socioeconomic stressors-may provide important protective influences on children's internalizing symptom trajectories.

Coping and empowerment preventive intervention buffers early adolescent neuroendocrine-related risk for internalizing problems

There is an absence of mechanism-driven interventions equipped to reduce the large mental health disparities that exist for preadolescent youth living in poverty. Building a Strong Identity and Coping Skills (BaSICS) is a preventive intervention designed to target multiple aspects of poverty-related stress adaptation, including altered neuroendocrine function. The purpose of the current study was to examine whether pre-post shifts in preadolescent hypothalamic-pituitary-adrenal (HPA) activation could longitudinally predict internalizing outcomes and to determine whether BaSICS could buffer such HPA-related risk for psychopathology. Low-income youth (n = 112) ages 11–12 years were randomized to the 16-session intervention or assessment-only control (53% intervention; 54% female; 40% Hispanic, 63% Black, 20% White). Youth completed questionnaires and the Trier Social Stress Test, and provided cortisol via saliva at six timepoints during the 90-minute assessment. Adjusting for pre-intervention Cortisol Area Under the Curve–Ground (CAUCg) scores and internalizing problems, post-intervention CAUCg and intervention main and interactive effects were modeled as predictors of internalizing outcomes across post-intervention, 6-month, and 12-month follow-up assessments using multilevel regression methods. A significant post-intervention CAUCg by intervention interaction emerged (B=1.198, SE=0.433, p = .006). For control youth, baseline-adjusted decreases in cortisol output were associated with increases in internalizing problems that remained stably elevated across follow-up assessments. For BaSICS youth, however, internalizing problems decreased and remained stably low following program delivery, irrespective of post-intervention increases or decreases in cortisol output. Findings illustrate how BaSICS may buffer against HPA-related risk for internalizing psychopathology and provide support for interventions targeting biological mechanisms of risk for low-income preadolescents.

Do dimensions of childhood adversity differ in their direct associations with youth psychopathology? A meta-analysis.

Growing evidence supports the unique pathways by which threat and deprivation, two core dimensions of adversity, confer risk for youth psychopathology. However, the extent to which these dimensions differ in their direct associations with youth psychopathology remains unclear. The primary aim of this preregistered meta-analysis was to synthesize the associations between threat, deprivation, internalizing, externalizing, and trauma-specific psychopathology. Because threat is proposed to be directly linked with socioemotional development, we hypothesized that the magnitude of associations between threat and psychopathology would be larger than those with deprivation. We conducted a search for peer-reviewed articles in English using PubMed and PsycINFO databases through August 2022. Studies that assessed both threat and deprivation and used previously validated measures of youth psychopathology were included. One hundred and twenty-seven articles were included in the synthesis (N = 163,767). Results of our three-level meta-analyses indicated that adversity dimension significantly moderated the associations between adversity and psychopathology, such that the magnitude of effects for threat (r's = .21-26) were consistently larger than those for deprivation (r's = .16-.19). These differences were more pronounced when accounting for the threat-deprivation correlation. Additional significant moderators included emotional abuse and youth self-report of adversity. Findings are consistent with the Dimensional Model of Adversity and Psychopathology, with clinical, research, and policy implications.

Adolescents' mental health, problematic internet use, and their parents' rules on internet use: A latent profile analysis

This study explored the connection between adolescent problematic internet use (PIU), mental health, and parents’ rules on internet use. From a person-centered approach, this study considered the coexistence of multiple mental health indicators for adolescents, including psychopathological risks (i.e., depressive symptoms, anxiety, and loneliness) and psychosocial well-being (i.e., social support, meaning, and competence). A latent profile analysis of 4592 U.S. adolescents revealed five distinct mental health profiles, with adolescents having psychopathological risks being most susceptible to PIU. Additionally, parents reported their rules on adolescent internet use. Strict parental rules on time increased PIU for adolescents of psychopathological risks, while restrictions on content viewed online reduced chances of PIU for these adolescents. These findings offer a deeper understanding of the complex mental health experiences of U.S. adolescents and underscore the significance of person-centered associations between mental health and PIU.

How is trauma a transdiagnostic risk factor? A biopsychosocial model of risk and protective mechanisms following childhood trauma

Abstract Traumatic exposure is a common global problem across nations. It is currently well established that childhood trauma is associated with increased risk for psychopathology transdiagnostically, with children having experienced trauma being twice as likely to develop a mental health condition compared to those who have never experienced trauma. According to population-based studies, this heightened risk for the emergence of mental health disorders persists throughout adolescence and adulthood. The risk for psychopathology seems to be most marked in children exposed to interpersonal violence (child emotional and physical abuse, neglect, sexual violence). In this presentation, we will summarize the results of an increasing number of published studies that have examined the mechanisms underlying vulnerability to psychopathology following childhood trauma and protective factors that buffer this risk. Specifically, we will highlight the role of emotion dysregulation and interpersonal difficulties, related to disrupted threat processing following trauma exposure, in mediating the impact of trauma on internalizing and externalizing symptoms. Research studies have also identified protective factors accross the lifespan that might mitigate these outcomes, including social support and emotional skills building. Based on this review, we will suggest a conceptual transdiagnostic and biopsychosocial model of risk and resilience, which can provide opportunities and targets for early interventions and treatment, at the primary and secondary healthcare levels, as well as the social, public health and community levels. Our model is based on a socioecological and multisystemic paradigm of risk and resilience, where resilience is conceptualized as an interaction between individuals and resourceful environments and communities.Disclosure of InterestNone Declared

Positive life changes during the COVID-19 pandemic moderate the association between mothers’ COVID-related stressors and psychopathology

BackgroundAmple research has documented the potential of both negative and positive impacts secondary to the COVID-19 pandemic on global mental health in adults and families, but less work has focused on mothers who experience economic marginalization. This longitudinal study aims to assess the impact of positive changes from the pandemic on the association between COVID-related stressors and psychopathology before and after the start of the pandemic. MethodsSeventy-five mothers from low income, economically marginalized backgrounds (mean age=30 years, 80 % Black) completed a pre-pandemic visit (T1;2015-2019) and an online survey (T2;2020-2021) mid-pandemic. The study assessed mother's depressive and posttraumatic stress symptoms and lifetime adversity, COVID-19 related stressors, and positive changes associated with the pandemic. ResultsControlling for pre-pandemic psychopathology symptoms, lifetime adversity and educational attainment, there was a significant, positive association between exposure to COVID-19 related stressors and risk for T2 psychopathology. Positive life changes buffered this association, however, such that exposure to COVID-19 related stressors and psychopathology were unrelated for mothers who reported a moderate to high level of positive changes associated with the pandemic. LimitationsThe sample was small and generalizability of results is limited. ConclusionsThe pandemic was associated with an increase in mental health problems and unique stressors, especially among caregivers who are low-income. These findings shine light on how both material and psychological access to positive experiences (e.g., more time with family) can buffer the impact of stressors on mental health symptoms.

Effect of (R)-2-Amino-6-(1R,2S)-1,2-Dihydroxypropyl)-5,6,7,8-Tetrahydropterin-4(3H)-One and Its Structural Analogues on the Temperature Stability of Tryptophan Hydroxylase 2 with the P447R Mutation.

The enzyme tryptophan hydroxylase 2 (TPH2) catalyzes the hydroxylation of L-tryptophan to L-5-hydroxytryptophan (5-HTP), the first and the key step in 5-HT synthesis in the mammalian brain. Mutations in the human Tph2 gene reducing enzyme activity increase the risk of psychopathology. Pharmacological chaperones are small molecules that can specifically bind to mutant protein molecules, restore their disturbed 3D structure to the native state, and increase their stability and functional activity. The chaperone activity of (R)-2-amino-6-(1R,2S)-1,2-dihydroxypropyl)-5,6,7,8-tetrahydropterin-4(3H)-one (BH4) is expressed by increasing the in vitro thermal stability of mutant tyrosine hydroxylase and phenylalanine hydroxylase molecules which are similar to TPH2 in their structure and characteristics. The P447R substitution in the mouse TPH2 molecule results in a 2-fold decrease in enzyme activity in their brains. We studied the effect of this mutation on the TPH2 thermal stability, as well as on the ability of BH4 and its 8 structural analogues to increase the thermal stability of the mutant TPH2 from midbrain extracts of BALB/C mice. Temperature stability was studied by the decrease in enzyme activity during its heating for 2 min at increasing temperatures and was evaluated by the T50 value that is the temperature at which the enzyme activity decreased by half. For the mutant TPH2, the T50 value was decreased compared to the wild type enzyme. BH4 and its closest structural analogue, 6-methyl-5,6,7,8-tetrahydropterin, increased the T50 value, i.e., exhibited chaperone activity. Other close BH4 analogs, 6,7-dimethyl-5,6,7,8-tetrahydropterin and folic acid, were not effective. It can be assumed that BH4 can be effective in the treatment of mental disorders caused by mutations in the Tph2 gene.

Early Infant Prefrontal Cortical Microstructure Predicts Present and Future Emotionality

BackgroundHigh levels of infant negative emotionality (NE) and low positive emotionality (PE) predict future emotional and behavioral problems. The prefrontal cortex (PFC) supports emotional regulation, with each PFC subregion specializing in specific emotional processes. Neurite orientation dispersion and density imaging estimates microstructural integrity and myelination via the neurite density index (NDI) and dispersion via the orientation dispersion index (ODI), with potential to more accurately evaluate microstructural alterations in the developing brain. Yet, no study has used these indices to examine associations between PFC microstructure and concurrent or developing infant emotionality. MethodsWe modeled PFC subregional NDI and ODI at 3 months with caregiver-reported infant NE and PE at 3 months (n = 61) and at 9 months (n = 50), using multivariable and subsequent bivariate regression models. ResultsThe most robust statistically significant findings were positive associations among 3-month rostral anterior cingulate cortex (ACC) ODI and caudal ACC NDI and concurrent NE, a positive association between 3-month lateral orbitofrontal cortex ODI and prospective NE, and a negative association between 3-month dorsolateral PFC ODI and concurrent PE. Multivariate models also revealed that other PFC subregional microstructure measures, as well as infant and caregiver sociodemographic and clinical factors, predicted infant 3- and 9-month NE and PE. ConclusionsGreater NDI and ODI, reflecting greater microstructural complexity, in PFC regions supporting salience perception (rostral ACC), decision making (lateral orbitofrontal cortex), action selection (caudal ACC), and attentional processes (dorsolateral PFC) might result in greater integration of these subregions with other neural networks and greater attention to salient negative external cues, thus higher NE and/or lower PE. These findings provide potential infant cortical markers of future psychopathology risk.

Family Talk versus usual services in improving child and family psychosocial functioning in families with parental mental illness: a randomised controlled trial and cost analysis.

Parental mental illness (PMI) is common and places children at high risk of developing psychological disorders. Family Talk (FT) is a well-known, whole-family, 7-session intervention designed to reduce the risk of transgenerational psychopathology. However, very few larger-scale evaluations of FT (across only a limited number of settings) have been conducted to date while there have been no cost analyses. This study aimed to assess the effectiveness and costs of delivering FT in improving child and family psychosocial functioning in families with PMI within routine mental health settings. A total of 83 families with PMI, with children aged 5-18 years, were randomly assigned on a 2:1 ratio to receive either the FT intervention (n=55 families) or usual services (n=28 families) across 10 adult, child and primary care mental health sites in Ireland. Parental disorders included anxiety/depression (57%), Bipolar Disorder (20%), Borderline Personality Disorder (12%), Post-Traumatic Stress Disorder (8%) and psychosis (2%). Detailed assessments with parents were conducted at baseline and 6-month follow up. FT led to significant improvements in family functioning and child behaviour at 6-month follow up when compared to usual services, with medium effect sizes indicated. Parent participants with lower mental health literacy at baseline also showed significant post-intervention improvements. Those parents with less severe mental illness at baseline, and families with more partner and economic supports, reported additional significant post-intervention improvements in child depression/anxiety and parental mental health symptoms. The cost of FT amounted to €761.50 per family, although this decreased to €415.31 when recurring costs only were included. The findings from this study, which was conducted within the context of a national programme to introduce family-focused practice in Ireland, demonstrate that FT is a low-cost intervention that improved child and family psychosocial functioning across different mental health disorders within routine adult, child and primary care mental health services. The findings contribute to the growing evidence base for FT, and provide a robust basis to inform practice and policy development for families with parental mental illness both in Ireland and elsewhere. https://www.isrctn.com/ISRCTN13365858, identifier ISRCTN13365858.

The influence of friendships on the mental health of maltreated youth: A pre-registered systematic review using a developmental psychopathology perspective.

Friendships are a potential factor that influence maltreated children's risk for psychopathology. This systematic review examined (1) how friendships influence the association between child maltreatment and psychopathology and (2) developmental differences in how friendships influence this association. Four databases were searched. Inclusion criteria were primary study, quantitative, measures of maltreatment and friendship up to the age of 18 years, measures of psychopathology up to the age of 24 years, and a non-maltreated sample. Exclusion criteria were qualitative, reviews or meta-analyses, no distinction between maltreatment and other trauma, and no differentiation between friendships and other support. Risk of bias was assessed. Data were narratively synthesized. Two hundred thirty-five articles were retrieved for full review. Fourteen met inclusion criteria (N = 98,676 participants). Eleven of the fourteen studies found that some aspect of friendships influenced the association between maltreatment and psychopathology, with positive qualities generally decreasing risk and negative qualities increasing risk for psychopathology. However, peer support exacerbated maltreated children's risk for psychopathology in two studies. Only three studies assessed friendship prior to adolescence, which precluded conclusions regarding developmental differences. Future research should consider developmental differences and use findings and validated measures from the peer relations literature to better understand how friendships influence maltreated youth's vulnerability to psychopathology.

Age-dependent associations between RSA reactivity, affective and cognitive regulation, and psychopathology risk in young children exposed to varying levels of socioeconomic disadvantage.

This study examined autonomic nervous system activity (respiratory sinus arrhythmia [RSA]) as a biomarker of psychopathology in an ethnically and socioeconomically diverse sample (N=57) of young children ages 4-7years. RSA was measured at baseline and across four standardized tasks designed to assess self-regulation in both affective (i.e., "hot") and cognitive (i.e., "cool") contexts during early childhood. Our findings reveal that age moderated RSA activity, such that reduced RSA suppression was associated with a heightened risk of externalizing problems among older children during "cool" and "hot" contexts; for younger children, only RSA suppression during "hot" contexts predicted externalizing risk. The influence of socioeconomic disadvantage did not moderate the relationship between RSA and the risk of psychopathology, and there were minimal associations between RSA suppression and internalizing symptoms at this age range. These results suggest that autonomic variability may be a more effective predictor of psychopathology risk in older children, perhaps as they transition into formal schooling and face increasingly complex cognitive and social demands. Findings have implications for the identification of psychopathology in early developmental periods when regulation over emotions becomes essential for academic and social success.

Neighborhood disadvantage and parenting predict longitudinal clustering of uncinate fasciculus microstructural integrity and clinical symptomatology in adolescents

Parenting behaviors and neighborhood environment influence the development of adolescents’ brains and behaviors. Simultaneous trajectories of brain and behavior, however, are understudied, especially in these environmental contexts. In this four-wave study spanning 9–18 years of age (N=224 at baseline, N=138 at final assessment) we used longitudinal k-means clustering to identify clusters of participants with distinct trajectories of uncinate fasciculus (UF) fractional anisotropy (FA) and anxiety symptoms; we examined behavioral outcomes and identified environmental factors that predicted cluster membership. We identified three clusters of participants: 1) high UF FA and low symptoms (“low-risk”); 2) low UF FA and high symptoms (“high-risk”); and 3) low UF FA and low symptoms (“resilient”). Adolescents in disadvantaged neighborhoods were more likely to be in the resilient than high-risk cluster if they also experienced maternal warmth. Thus, neighborhood disadvantage may confer neural risk for psychopathology that can be buffered by maternal warmth, highlighting the importance of considering multiple environmental influences in understanding emotional and neural development in youth.

Relations Between Neighborhood Disadvantage and Electrocortical Reward Processing in Youth at High and Low Risk for Depression.

Neighborhood-level disadvantage during childhood is a determinant of health that is hypothesized to confer risk for psychopathology via alterations in neuro-affective processing, including reward responsiveness. However, little research has examined the impact of socioeconomic disadvantage assessed at the community-level on reward processing, which may have important implications for targeted dissemination efforts. Furthermore, not all youth exposed to neighborhood disadvantage may exhibit alterations in reward reactivity, highlighting the need to consider factors that may exacerbate risk for blunted reward reactivity. The current study examined associations between geocoded indices of neighborhood disadvantage and electrocortical reward responsivity in youth and tested whether findings were moderated by maternal history of depression. The sample included 137 youth recruited for studies on the intergenerational transmission of depression. Neighborhood disadvantage was assessed using the Area Deprivation Index (ADI) while the reward positivity (RewP), an event-related potential, indexed reward response. Results revealed a significant interaction between ADI and maternal history of depression on youth RewP, such that greater neighborhood disadvantage was significantly associated with lower reward responsiveness, but only for youth with a maternal history of depression. Results were maintained controlling for youth internalizing symptoms and individual-level socioeconomic factors. Findings suggest that neighborhood disadvantage may impact youth neural reward processing, at least partially independently of individual risk factors, for youth with a maternal history of depression. If replicated, results suggest intervention efforts may be implemented at the community level to enhance reward responsiveness, specifically for youth living in low-resourced neighborhoods with a maternal history of depression.

How a general vulnerability for psychopathology during adolescence manifests in young adults' daily lives.

There is widespread interest in the general factor of psychopathology or 'p factor', which has been proposed to reflect vulnerability to psychopathology. We examined to what extent this 'vulnerability' is associated with dysregulations in affect and behavior that occur in daily life. As such we hoped to provide an account of how this vulnerability may be maintained. We used data from the Tracking Adolescents' Individual Lives Survey (TRAILS; N = 2,772) collected at ages 11, 14, 16, 19, and 22 years to fit a bifactor model with a general psychopathology factor, alongside internalizing, externalizing (EXT), attention-deficit/hyperactivity, and autism spectrum problem domains. Following the fifth TRAILS assessment, a subsample of participants (n = 133, age = 22.6, 43% women) with heightened risk for psychopathology completed a 6-month daily diary protocol with one assessment each day. Using a dynamic structural equation approach, we examined to what extent mean intensity, variability, inertia, and within-day co-occurrence of EXT, anxious-tense, and depressed-withdrawn affects and behaviors were associated with general factor scores. Unexpectedly, higher general factor scores were not associated with higher mean intensity of any of the three types of daily negative affects and behaviors, but were associated with higher variability and less carryover (inertia) EXT affects and behaviors. We showed that individual differences in general factor scores do not manifest as differences in average levels of daily affects and behaviors, but instead were related to a type of EXT reactivity to the environment. Future research is necessary to investigate whether reactive irritable moods may be involved in or signal vulnerability sustained psychopathology.

The neurobiological effects of childhood maltreatment on brain structure, function, and attachment.

Childhood maltreatment is a risk factor for psychopathologies, and influences brain development at specific periods, particularly during early childhood and adolescence. This narrative review addresses phenotypic alterations in sensory systems associated with specific types of childhood maltreatment exposure, periods of vulnerability to the neurobiological effects of maltreatment, and the relationships between childhood maltreatment and brain structure, function, connectivity, and network architecture; psychopathology; and resilience. It also addresses neurobiological alterations associated with maternal communication and attachment disturbances, and uses laboratory-based measures during infancy and case-control studies to elucidate neurobiological alterations in reactive attachment disorders in children with maltreatment histories. Moreover, we review studies on the acute effects of oxytocin on reactive attachment disorder and maltreatment and methylation of oxytocin regulatory genes. Epigenetic changes may play a critical role in initiating or producing the atypical structural and functional brain alterations associated with childhood maltreatment. However, these changes could be reversed through psychological and pharmacological interventions, and by anticipating or preventing the emergence of brain alterations and subsequent psychopathological risks.

Stability of and Change in Psychopathological Risk Levels in Pre-Early Adolescents before, during, and after Their Study Sojourns: A Descriptive Study.

Adolescents can benefit from studying abroad in terms of personal development, cross-cultural encounters, and academic enrichment. This article digs into the psychological challenges that students may face before and during their study abroad, focusing on the emotional components of their experiences. The current descriptive study sought to assess the stability or change in levels of psychopathological risk in a sample of N = 195 adolescents before and during a study abroad sojourn. To examine psychological symptoms in pre-adolescents, teachers were asked to complete a report-form questionnaire. The findings of this study revealed that students' psychological functioning changed significantly after their study abroad experience. Anxious/depressed and withdrawn ratings specifically increased from the pre-sojourn assessment (T1) to the evaluation during the stay (T2), then remained consistent (T3). In addition, the scores for rule-breaking and aggressive conduct changed, increasing from T1 to T2 and then decreasing from T2 to T3. This trend implies that teenagers may struggle with behavioral challenges early in their study abroad experience, but subsequently adjust and improve their conduct as they grow more used to the new environment. this research offers insight into the emotional and behavioral issues that adolescents face when studying abroad, underlining the significance of treating psychopathological risk factors in this demographic.
