Longitudinal associations between changes in peer victimization and emotion dysregulation across adolescence.

Emotion dysregulation emerges from an interaction between individual factors and environmental factors. Changes in biological, cognitive, and social systems that characterize adolescence create a complex array of environmental factors contributing to emotion dysregulation during this developmental period. In particular, peer victimization (PV) has long-term consequences for emotion dysregulation. Yet, previous research has also indicated that emotion dysregulation can be both an antecedent to and outcome of PV. The present study evaluated reciprocal associations between longitudinal changes within repeated measures of PV and emotion dysregulation across adolescence and into young adulthood. The sample included 167 adolescents (53% male, Mage = 14.07 years at Time 1) who participated in a longitudinal study across five time points, with approximately 1 year between each assessment. Latent change score modeling was used to examine reciprocal associations between PV and emotion dysregulation. Results emphasize bidirectional associations between PV and emotion dysregulation. Consistent with social information processing theory, greater emotion dysregulation predicted greater relational and overt victimization over time. Moreover, higher overt victimization predicted increases in emotion dysregulation. Our results offer insights toward developmentally informed longitudinal, transactional models linking negative social environments, and emotion dysregulation development across adolescence and into young adulthood.

Longitudinal Associations Among Socioeconomic Status, Delay Discounting, and Substance Use in Adolescence.

It is unclear how delay discounting and substance use develop across adolescence and whether contextual factors alter their trajectories. The present study used a longitudinal design to examine whether socioeconomic status is related to developmental trajectories of delay discounting and substance use across adolescence. The sample included 167 adolescents (Mage = 14 at Time 1; 53% male) and their parents who participated annually across four years. Parents reported SES at Time 1 and adolescents completed delay discounting behavioral assessments and substance use questionnaires at Times 1 to 4. Bivariate latent growth curve modeling revealed that low SES was related to steeper increases in substance use from age 14 through 17, mediated through elevated delay discounting at age 14. The findings clarify the mediating role of delay discounting in linking family economic environment to the progression of substance use.

A machine-learning approach for differentiating borderline personality disorder from community participants with brain-wide functional connectivity.

BACKGROUND: Functional connectivity has garnered interest as a potential biomarker of psychiatric disorders including borderline personality disorder (BPD). However, small sample sizes and lack of within-study replications have led to divergent findings with no clear spatial foci. AIMS: Evaluate discriminative performance and generalizability of functional connectivity markers for BPD. METHOD: Whole-brain fMRI resting state functional connectivity in matched subsamples of 116 BPD and 72 control individuals defined by three grouping strategies. We predicted BPD status using classifiers with repeated cross-validation based on multiscale functional connectivity within and between regions of interest (ROIs) covering the whole brain-global ROI-based network, seed-based ROI-connectivity, functional consistency, and voxel-to-voxel connectivity-and evaluated the generalizability of the classification in the left-out portion of non-matched data. RESULTS: Full-brain connectivity allowed classification (∼70 %) of BPD patients vs. controls in matched inner cross-validation. The classification remained significant when applied to unmatched out-of-sample data (∼61-70 %). Highest seed-based accuracies were in a similar range to global accuracies (∼70-75 %), but spatially more specific. The most discriminative seed regions included midline, temporal and somatomotor regions. Univariate connectivity values were not predictive of BPD after multiple comparison corrections, but weak local effects coincided with the most discriminative seed-ROIs. Highest accuracies were achieved with a full clinical interview while self-report results remained at chance level. LIMITATIONS: The accuracies vary considerably between random sub-samples of the population, global signal and covariates limiting the practical applicability. CONCLUSIONS: Spatially distributed functional connectivity patterns are moderately predictive of BPD despite heterogeneity of the patient population.

Family socioeconomic status and adolescent substance use: The role of parent-adolescent brain similarity and parental monitoring.

Greater neural similarity between parents and adolescents may reduce adolescent substance use. Among 70 parent-adolescent dyads, we tested a longitudinal path model in which family economic environment is related to adolescent substance use, directly and indirectly through parent-adolescent neural similarity and parental monitoring. Neural similarity was measured as parent-adolescent pattern similarity in functional brain connectivity at Time 1. Parents reported socioeconomic status and parental monitoring at Time 1. Adolescents reported parental monitoring at Time 1 and substance use at Time 2. Higher family socioeconomic status was associated with greater neural similarity. Greater neural similarity was associated with lower adolescent substance use, mediated through greater adolescent-perceived parental monitoring. Parent-adolescent neural similarity may attenuate adolescent substance use by bolstering parental monitoring. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Psychopathology as long-term sequelae of maltreatment and socioeconomic disadvantage: Neurocognitive development perspectives.

Neuroscience research underscores the critical impact of adverse experiences on brain development. Yet, there is limited understanding of the specific pathways linking adverse experiences to accelerated or delayed brain development and their ultimate contributions to psychopathology. Here, we present new longitudinal data demonstrating that neurocognitive functioning during adolescence, as affected by adverse experiences, predicts psychopathology during young adulthood. The sample included 167 participants (52% male) assessed in adolescence and young adulthood. Adverse experiences were measured by early maltreatment experiences and low family socioeconomic status. Cognitive control was assessed by neural activation and behavioral performance during the Multi-Source Interference Task. Psychopathology was measured by self-reported internalizing and externalizing symptomatology. Results indicated that higher maltreatment predicted heightened frontoparietal activation during cognitive control, indicating delayed neurodevelopment, which, in turn predicted higher internalizing and externalizing symptomatology. Furthermore, higher maltreatment predicted a steeper decline in frontoparietal activation across adolescence, indicating neural plasticity in cognitive control-related brain development, which was associated with lower internalizing symptomatology. Our results elucidate the crucial role of neurocognitive development in the processes linking adverse experiences and psychopathology. Implications of the findings and directions for future research on the effects of adverse experiences on brain development are discussed.

Longitudinal associations between dimensions of maltreatment and internalizing symptoms in late adolescence: The role of inflammation during the COVID-19 pandemic.

Childhood adversity and depression have been linked with heightened inflammation. However, few longitudinal studies examine how dimensions of maltreatment (i.e., abuse and neglect) differentially impact pathways to heightened inflammation and internalizing symptoms. The present study examined effects of abuse and neglect on (1) internalizing symptoms through inflammation, and (2) on inflammation through internalizing symptoms across 3 years of adolescence in the context of the COVID-19 pandemic. In a sample of 78 adolescents, significant indirect effects revealed that childhood abuse, not neglect, significantly predicted future internalizing symptoms, which predicted future heighted C-reactive protein (CRP). Using prospective longitudinal data, these findings emphasize the importance of examining distinct forms of maltreatment in understanding the developmental pathways connecting early adversity, internalizing symptoms, and inflammation.

Brain Similarity as a Protective Factor in the Longitudinal Pathway Linking Household Chaos, Parenting, and Substance Use.

BACKGROUND: Socioecological factors such as family environment and parenting behaviors contribute to the development of substance use. While biobehavioral synchrony has been suggested as the foundation for resilience that can modulate environmental effects on development, the role of brain similarity that attenuates deleterious effects of environmental contexts has not been clearly understood. We tested whether parent-adolescent neural similarity-the level of pattern similarity between parent-adolescent functional brain connectivity representing the level of attunement within each dyad-moderates the longitudinal pathways in which household chaos (a stressor) predicts adolescent substance use directly and indirectly via parental monitoring. METHODS: In a sample of 70 parent-adolescent dyads, similarity in resting-state brain activity was identified using multipattern connectivity similarity estimation. Adolescents and parents reported on household chaos and parental monitoring, and adolescent substance use was assessed at a 1-year follow-up. RESULTS: The moderated mediation model indicated that for adolescents with low neural similarity, but not high neural similarity, greater household chaos predicted higher substance use over time directly and indirectly via lower parental monitoring. Our data also indicated differential susceptibility in the overall association between household chaos and substance use: Adolescents with low neural similarity exhibited high substance use under high household chaos but low substance use under low household chaos. CONCLUSIONS: Neural similarity acts as a protective factor such that the detrimental effects of suboptimal family environment and parenting behaviors on the development of adolescent health risk behaviors may be attenuated by neural similarity within parent-adolescent bonds.

Pretreatment characteristics associated with symptom reduction during group cognitive processing therapy versus exposure therapy for PTSD: an exploratory study of Veterans.

Exposure and cognitive-based therapies are both effective for PTSD, but knowledge of which intervention is best for which patient is lacking. This lack of knowledge is particularly noticeable for group treatments, as no study has examined whether responses to different group therapies are associated with different pretreatment characteristics. Here, we explored whether pretreatment levels of three types of psychological characteristics-PTSD symptom clusters, posttraumatic cognitions, and emotion regulation difficulties-were associated with symptom reduction during group-delivered cognitive versus exposure-based PTSD treatment. Participants were Veterans with PTSD drawn from two previous clinical trials: one of group CPT (GCPT; n = 32) and the other of group-based exposure therapy (GBET; n = 21). Growth curve modeling was used to identify pretreatment variables that predicted weekly PTSD symptom changes during each therapy. Higher posttraumatic cognitions at pretreatment predicted steeper PTSD symptom reduction during GCPT but not GBET. Additionally, symptom reduction during each therapy was associated with different pretreatment emotion regulation difficulties: difficulties with goal-directed behavior for GBET and lack of emotional clarity and limited access to emotion regulation strategies for GCPT. These findings suggest that assigning Veterans to a group PTSD therapy that better matches their pretreatment psychological profile might facilitate a better therapeutic response.

Noradrenaline tracks emotional modulation of attention in human amygdala.

The noradrenaline (NA) system is one of the brain's major neuromodulatory systems; it originates in a small midbrain nucleus, the locus coeruleus (LC), and projects widely throughout the brain.1,2 The LC-NA system is believed to regulate arousal and attention3,4 and is a pharmacological target in multiple clinical conditions.5,6,7 Yet our understanding of its role in health and disease has been impeded by a lack of direct recordings in humans. Here, we address this problem by showing that electrochemical estimates of sub-second NA dynamics can be obtained using clinical depth electrodes implanted for epilepsy monitoring. We made these recordings in the amygdala, an evolutionarily ancient structure that supports emotional processing8,9 and receives dense LC-NA projections,10 while patients (n = 3) performed a visual affective oddball task. The task was designed to induce different cognitive states, with the oddball stimuli involving emotionally evocative images,11 which varied in terms of arousal (low versus high) and valence (negative versus positive). Consistent with theory, the NA estimates tracked the emotional modulation of attention, with a stronger oddball response in a high-arousal state. Parallel estimates of pupil dilation, a common behavioral proxy for LC-NA activity,12 supported a hypothesis that pupil-NA coupling changes with cognitive state,13,14 with the pupil and NA estimates being positively correlated for oddball stimuli in a high-arousal but not a low-arousal state. Our study provides proof of concept that neuromodulator monitoring is now possible using depth electrodes in standard clinical use.

Risk-related brain activation is linked to longitudinal changes in adolescent health risk behaviors.

Middle adolescence is the period of development during which youth begin to engage in health risk behaviors such as delinquent behavior and substance use. A promising mechanism for guiding adolescents away from risky choices is the extent to which adolescents are sensitive to the likelihood of receiving valued outcomes. Few studies have examined longitudinal change in adolescent risky decision making and its neural correlates. To this end, the present longitudinal three-wave study (Nw1 = 157, Mw1= 13.50 years; Nw2 = 148, Mw2= 14.52 years; Nw3 = 143, Mw3= 15.55 years) investigated the ontogeny of mid-adolescent behavioral and neural risk sensitivity, and their baseline relations to longitudinal self-reported health risk behaviors. Results showed that adolescents became more sensitive to risk both in behavior and the brain during middle adolescence. Across three years, we observed lower risk-taking and greater risk-related activation in the bilateral insular cortex. When examining how baseline levels of risk sensitivity were related to longitudinal changes in real-life health risk behaviors, we found that Wave 1 insular activity was related to increases in self-reported health risk behaviors over the three years. This research highlights the normative maturation of risk-related processes at the behavioral and neural levels during mid-adolescence.

Longitudinal Associations Between Peer Victimization and Positive and Negative Social Risk Taking in Adolescence and Young Adulthood.

Adolescence is characterized by heightened risk taking, along with salient peer relationships. This study leveraged data from 167 adolescents across five years (M(SD)age = 15.05 (0.54) years at Time 1; 47% female) to examine how risk perception and peer victimization in adolescence interrelate and predict risk likelihood in young adulthood. Bivariate growth curve modeling revealed that higher initial levels of positive social risk perception predicted a slower decrease in relational victimization throughout adolescence. Higher initial levels of relational victimization in adolescence predicted higher negative social risk likelihood in young adulthood. Adolescents with heightened risk sensitivity to positive social risks may be vulnerable to relational victimization, and prevention efforts to reduce relational victimization may protect adolescents from future negative risk taking.

Parenting, emotion regulation, and externalizing symptomatology as adolescent antecedents to young adult health risk behaviors.

This study used longitudinal data to elucidate how trajectories of negative parenting across adolescence are associated with young adult health risk behaviors (HRBs) by testing difficulties with emotion regulation and externalizing symptomatology as sequential underlying mediators. The sample included 167 adolescents (53% males, Mage  = 14 at Time 1 and Mage  = 18 at Time 5) who were assessed five times. Adolescents self-reported on negative parenting, emotion regulation, externalizing symptomatology, and engagement in HRBs. Results suggest that increasingly negative parenting across adolescence has adverse consequences for emotion regulation development and in turn, externalizing symptomatology, which confers risk for young adult HRBs. Results offer insights towards mechanisms for prevention and intervention and public health policy aimed at reducing the prevalence and consequences of engagement in HRBs.

Differential Associations of Adversity Profiles with Adolescent Cognitive Control and Psychopathology.

Adverse childhood experiences are common and have long-term consequences for biological and psychosocial adjustment. We used a person-centered approach to characterize distinct profiles of adversity in early adolescence and examined associations with later cognitive control and psychopathology. The sample included 167 adolescents (47% female) and their primary caregivers who participated in a longitudinal study across four time points (approximately one year between assessments). At Time 1 (Mage = 14 years), we measured seven indicators of adversity: socioeconomic disadvantage, abuse, neglect, household chaos, parent substance use, parent depression, and negative life events. At Times 2-4, adolescents' behavioral performance and functional activation during a cognitive control task were measured. At Time 5, adolescents and their caregiver reported on adolescent internalizing and externalizing symptomatology. Using latent profile analysis, we identified four distinct adversity subgroups: a low exposure group, a neglect group, a household instability group, and a poly-adversity group. These groups significantly differed on subsequent levels of psychopathology, but not cognitive control. Specifically, the poly-adversity group reported significantly higher levels of both internalizing and externalizing symptomatology relative to the low exposure group, and the household instability group demonstrated elevated risk for externalizing symptomatology. When using a cumulative risk approach, higher levels of adversity exposure were associated with significantly worse cognitive control performance (but not neural activation). These results suggest that psychopathology outcomes may be differentially predicted by distinct patterns of risk, and that cognitive control impairment may be more strongly predicted by cumulative risk.

Development of cognitive control during adolescence: The integrative effects of family socioeconomic status and parenting behaviors.

Cognitive control is of great interest to researchers and practitioners. The concurrent association between family socioeconomic status (SES) and adolescent cognitive control is well-documented. However, little is known about whether and how SES relates to individual differences in the development of adolescent cognitive control. The current four-year longitudinal investigation (N = 167, 13-14 years at Wave 1) used multi-source interference task performance (reaction time in interference correct trials minus neutral correct trials) and corresponding neural activities (blood oxygen level dependent contrast of interference versus neutral conditions) as measures of cognitive control. SES and parenting behaviors (warmth, monitoring) were measured through surveys. We examined direct and indirect effects of earlier SES on the development of cognitive control via parenting behaviors; the moderating effect of parenting also was explored. Results of latent growth modeling (LGM) revealed significant interactive effects between SES and parenting predicting behavioral and neural measures of cognitive control. Lower family SES was associated with poorer cognitive performance when coupled with low parental warmth. In contrast, higher family SES was associated with greater improvement in performance, as well as a higher intercept and steeper decrease in frontoparietal activation over time, when coupled with high parental monitoring. These findings extend prior cross-sectional evidence to show the moderating effect of the parenting environment on the potential effects of SES on developmental changes in adolescent cognitive control.

Longitudinal Associations between Social Relationships and Alcohol Use from Adolescence into Young Adulthood: The Role of Religiousness.

As adolescence is a time characterized by rapid changes in social relationships as well as an increase in risk-taking behaviors, this prospective longitudinal study examined whether social involvement and social alienation are associated with changes in alcohol use from adolescence into young adulthood moderated by organizational and personal religiousness. Participants were 167 adolescents (53% male) assessed five times between ages 14 and 18 years old. Latent change score modeling analyses indicated that social alienation was positively associated with greater increases in alcohol use among those with low organizational religiousness and those with low personal religiousness in early adolescence and during the transition into young adulthood. The findings demonstrate the detrimental effects of social relationship risk factors that promote alcohol use during adolescence into young adulthood. The results further highlight the protective roles of organizational and personal religiousness acting as additional sources of social engagement experiences to modulate the effects of social alienation predicting alcohol use progression and provide evidence for the positive impact religiousness has on healthy adolescent development.

Neural cognitive control moderates the longitudinal link between hedonia and substance use across adolescence.

Hedonic dysregulation is evident in addiction and substance use disorders, but it is not clearly understood how hedonic processes may interact with brain development related to cognitive control to influence risky decision making and substance use during adolescence. The present study used prospective longitudinal data to clarify the role of cognitive control in the link between hedonic experiences and the development of substance use during adolescence. Participants included 167 adolescents (53% male) assessed at four time points, annually. Adolescents participated in a functional magnetic resonance imaging (fMRI) session where blood-oxygen level dependent (BOLD) response was monitored during the Multi-Source- Interference Task to assess cognitive control. Substance use and hedonia were assessed using self-report. A two-group growth curve model of substance use with hedonia as a time-varying covariate indicated that higher levels of hedonia predicted higher substance use, but only in adolescents with higher activation in the frontoparietal regions and in the rostral anterior cingulate cortex during cognitive control. Results elucidate the moderating effects of neural cognitive control on associations between hedonia and adolescent substance use, suggesting that lower cognitive control functioning in the brain may exacerbate risk for substance use promoted by hedonia.

The mediating role of attachment and mentalising in the relationship between childhood maltreatment, self-harm and suicidality.

BACKGROUND: Although the relationship between childhood maltreatment, self-harm and suicidality is well-established, less is known about the mediating mechanisms explaining it. Based on a developmental mentalisation-based theoretical framework, childhood adversity compromises mentalising ability and attachment security, which in turn increase vulnerability to later stressors in adulthood. OBJECTIVE: This study aimed to investigate the role of attachment and mentalising as potential mechanisms in the relationship between childhood maltreatment, self-harm and suicidality. PARTICIPANTS AND SETTING: We recruited 907 adults from clinical and community settings in Greater London. METHODS: The study design was cross-sectional. Participants completed self-report questionnaires on retrospectively rated childhood trauma, and current attachment to the romantic partner, mentalising, self-harm, suicidal ideation and attempt. We used structural equation modelling to examine the data and conceptualized childhood maltreatment as a general factor in a confirmatory bifactor model. RESULTS: The results showed that childhood maltreatment was both directly associated with self-harm and suicidality and indirectly via the pathways of attachment and mentalising. CONCLUSIONS: These findings indicate that insecure attachment and impaired mentalising partially explain the association between childhood maltreatment, self-harm and suicidality. Clinically, they provide support for the potential of mentalisation-based therapy or other psychosocial interventions that aim to mitigate the risk of self-harm and suicidality among individuals who have experienced childhood maltreatment via increasing understanding of self and other mental states.

Do early responders and treatment non-responders offer guidance to make CPT group a more effective treatment?

BACKGROUND: Treatment dropout has been problematic with evidence-based treatments for posttraumatic stress disorder (PTSD), including cognitive processing therapy (CPT). This study sought to evaluate whether CPT group contributed to symptom improvement among treatment completers and non-completers. METHODS: Sixty-one Iraq and Afghanistan combat Veterans self-selected CPT group or treatment as usual (TAU) forming a convenience sample. Defining treatment completion as attending at least nine sessions: 18 completed treatment, 20 dropped-out (DOs); 20 completed TAU, 3 lost to TAU follow-up. RESULTS: Multiple Regression revealed significant pre-post-treatment improvement, the Clinician-Administered PTSD Scale (CAPS-IV, F(5, 40.1) = 2.53, p = 0.0436). Reviewing DOs' last available PTSD Checklist-Military Version scores before leaving treatment, six achieved clinically significant improvement of >10 points; seven a clinically reliable change of 5-10 points. CONCLUSION: These findings highlight that CPT group may be effective at reducing trauma-related symptoms among treatment completers and dropouts and point to the utility of a clinical definition of good treatment end-state.

Transactional relations between developmental trajectories of executive functioning and internalizing and externalizing symptomatology in adolescence.

Adolescence is a period of social, physical, and neurobiological transitions that may leave individuals more vulnerable to the development of internalizing and externalizing symptomatology. Extant research demonstrates that executive functioning (EF) is associated with psychopathology outcomes in adolescence; however, it has yet to be examined how EF and psychopathology develop transactionally over time. Data were collected from 167 adolescents (47% female, 13-14 years old at Time 1) and their primary caregiver over 4 years. At each time point, adolescents completed three behavioral tasks that capture the underlying dimensions of EF, and both adolescents and their primary caregiver completed measures of adolescent psychopathology. Latent growth curve modeling was used to test the associations between initial levels and trajectories of EF and psychopathology. Results indicated that higher initial levels of internalizing and externalizing symptomatology were associated with lower EF at Time 4 (controlling for Time 1 EF). Initial levels of EF did not predict changes in internalizing and externalizing symptomatology. These findings suggest that early psychopathology may be a risk factor for maladaptive EF development in adolescence.

Associations between developmental patterns of negative parenting and emotion regulation development across adolescence.

Research has documented changes in parenting practices and in emotion regulation (ER) during adolescence. However, developmental trajectories of these constructs and how they may be linked are not clearly known. The present study examined longitudinal associations between developmental trajectories of negative parenting and developmental trajectories of ER (e.g., abilities and strategy use, including cognitive reappraisal and suppression). The sample included 167 adolescents (53% males) who were first recruited at age 13 or 14 years and assessed annually four times. Adolescents self-reported on the perceived degree of their parent's negative parenting and ER. Growth mixture modeling revealed two distinct trajectories of negative parenting across adolescence: Class 1 contained the majority of adolescents (84%), with moderate initial levels of negative parenting that decreased across adolescence; Class 2 contained a smaller group of adolescents (16%), reporting moderate initial levels of negative parenting that increased across adolescence. Though growth curve modeling did not reveal significant growth in ER across time in the sample as a whole, results from a two-group model demonstrated that ER development significantly differs depending on adolescents' experiences of negative parenting trajectories. Adolescents experiencing decreases in negative parenting showed significant increases in ER abilities and no significant changes in suppression. Adolescents experiencing increases in negative parenting exhibited significant decreases in ER abilities. Adolescent's cognitive reappraisal was unaffected by negative parenting. The findings underscore the significant role of differential parenting environments in the development of ER abilities during adolescence. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
