Variability in adolescent reception of parental support: Testing the domain-matching hypothesis.

The present study investigated matches and mismatches between adolescent and parent socialization domains (i.e., protection, guidance) as related to adolescent reception of parental support during a laboratory-based social evaluation challenge. Participants were 80 early adolescents (Mage = 12.36 years, SD = 1.33, 55% males, 55% Black, 42.5% White, and 2.5% other races or ethnicities) and one parent or guardian per adolescent. Observational measures of parent socialization domains assessed sensitivity to adolescents' thoughts and feelings (protection domain) and prosocial behavioral advice (guidance domain). Measures of parallel adolescent socialization domains included self-reported discomfort during a social evaluation challenge (protection domain) and desire to continue the social evaluation challenge (guidance domain). Adolescent reception of parental support was assessed using an observational measure of adolescent attentiveness and responsiveness to the parent during a parent-adolescent discussion about how to approach the social evaluation challenge. Analyses of interactions between measures of parent and adolescent socialization domains revealed: (a) higher levels of adolescent-reported discomfort during the social evaluation challenge interfered with their reception of parental prosocial behavioral advice but did not enhance their reception of parental sensitivity, and (b) higher levels of adolescent-reported desire to continue the social evaluation challenge interfered with their reception of parental sensitivity but did not enhance their reception of parental prosocial behavioral advice. This study advances socialization research by identifying conditions under which adolescents are more and less receptive to supportive communication from parents.

Intergenerational transmission and the reinforcement of the political engagement gap: Identifying how university‐educated parents enable their children to become more politically interested during early adolescence

AbstractResearch consistently shows that parents' educational attainment is associated with their children's level of political interest. The life stage when this relationship is established and grows has been identified to be between the ages of 10 and 16. This paper identifies the social class‐based practices that drive the influence of parental education on the development of political interest among early adolescents and explains why the social gap grows at this point. The paper draws on two panel surveys, the Citizenship Education Longitudinal Study and the Understanding Society Youth Survey, and applies latent growth curve modelling and path analysis. The findings show that university‐educated parents influence the change in political interest of their children in early adolescence by raising their educational aspirations, enabling their access to political activities in school, choosing the school for their children, taking their children to museums and art galleries and influencing their children's friendship groups.

A Review of Behavioral and Pharmacological Treatments for Adult Trichotillomania

Trichotillomania (TTM) is a psychiatric disorder involving chronic, recurrent urges to pull out one’s own hair, arising frequently in childhood and early adolescence. This disorder predominantly affects women and has a high co-morbidity with many other psychiatric conditions. Currently, the etiology is unknown, which makes treating TTM extremely difficult. While the epidemiology and proposed causes will be discussed briefly, the primary purpose of this review is to provide a comprehensive, updated summary of the psychological and pharmacological management options for patients diagnosed with TTM, as new clinical trial data for previously studied and novel treatments have become available within the last decade. Of the behavioral interventions, cognitive behavioral therapy (CBT) and habit reversal training (HRT) have demonstrated the greatest improvements in hair-pulling severity, with HRT showing the most efficacy for long-term maintenance of progress. Pharmacological therapies with the most success include Olanzapine, Clomipramine, and N-Acetylcysteine, though larger replication studies are needed. Selective serotonin reuptake inhibitors (SSRIs) have yielded inconsistent results in clinical trials, yet they are frequently prescribed for TTM. Naltrexone, Dronabinol, and Inositol are emerging as potential treatments, but the results suggest that additional studies are needed. Future research directions include larger placebo-controlled pharmacological trials, exploring the efficacy of combined behavioral and pharmacological approaches compared to monotherapy, and delving into the potential genetic and neurochemical contributions that may underlie TTM.

Developmental Trajectories of Mental Health in Chinese Early Adolescents: School Climate and Future Orientation as Predictors.

There is growing support for the dual-continua model of mental health, which emphasizes psychopathology and well-being as related but distinct dimensions. Yet, little is known about how these dimensions co-develop from childhood to early adolescence and what factors predict their different trajectories. The current study aimed to identify distinct patterns of mental health in Chinese early adolescents, focusing on both psychopathological symptoms (i.e., depressive symptoms and self-harm behaviors) and subjective well-being (i.e., life satisfaction and affect balance). This study also examined the contributions of school climate and future orientation to these trajectories. A total of 1,057 students (Mage = 11.88, SDage = 1.67; 62.1% boys) completed four assessments over two years, with six-month intervals. Using parallel-process latent class growth modeling, we identified four groups: Flourishing (32.5%), Languishing (43.8%), Troubled with Stable Depressive Symptoms (16.1%), and Troubled with Increasing Self-Harm Risk (7.6%). Furthermore, school climate and future orientation contributed to adolescents' membership in these trajectories, either independently or jointly. Specifically, higher levels of future orientation combined with higher school climate were associated with a lower likelihood of belonging to the Troubled with Increasing Self-Harm Risk trajectory, compared to the Flourishing group. Our findings identified four distinct mental health trajectories consistent with the dual-continua model, and demonstrated that the development of psychopathology and well-being were not always inversely related (e.g., the Languishing group). Adolescents with unique developmental profiles may benefit from tailored intervention strategies that build on the personal and environmental assets of the adolescent.

The prevalence and predictors of metabolic dysfunction-associated steatotic liver disease and fibrosis/cirrhosis among adolescents/young adults.

We investigated the current prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and fibrosis/cirrhosis and identified at-risk populations for MASLD and MASLD-related fibrosis among US adolescents and young adults in the United States. Utilizing the National Health and Nutrition Examination Survey 2017-2020, the prevalence of MASLD and fibrosis/cirrhosis was assessed via controlled attenuation parameter (CAP) score and liver stiffness measurements by transient elastography in participants aged 12-29 years with at least one cardiometabolic criteria and absence of other chronic liver disease. Multivariable logistic regression was performed to determine predictors of MASLD and MASLD-related fibrosis. The overall prevalence of MASLD was 23.9% (95% CI: 21.3-26.5 for CAP ≥ 263 dB/m) and 17.3% (95% CI: 14.7-20.0 for ≥285 dB/m), respectively. The prevalence of fibrosis and cirrhosis in MASLD was 11.0% and 3.1%, respectively. When categorized by age, the prevalence of MASLD varied from 16.8% (of which 6.2% [fibrosis], 1.8% [cirrhosis]) in early and middle adolescents (12-17 years), to 25.5% (11.8% [fibrosis], 4.8% [cirrhosis]) in late adolescents and young adults (18-24 years), and to 30.4% (of which 13.2% [fibrosis] and 2.1% [cirrhosis]) in older young adults (25-29 years). The independent predictors for MASLD included male sex, Hispanic, non-Hispanic Asian, body mass index, and low HDL-cholesterol. In contrast, diabetes and body mass index were associated with an increased risk of fibrosis in individuals with MASLD. The prevalence of MASLD and related fibrosis in adolescents and young adults in the United States has reached a significant level, with a substantial proportion of cirrhosis.

Examining compulsive exercise as a risk factor for eating disorder symptoms in first-year college students using a latent change score modeling approach.

Research suggests that both compulsive exercise and eating disordered behaviors increase during college. Despite strong cross-sectional associations between compulsive exercise and eating disorders, it is unknown if compulsive exercise is a variable risk factor for eating disorders or simply a correlate. It was hypothesized that increases in compulsive exercise would significantly and prospectively predict increases in overall number of eating disorder symptoms over the study period. A total of 265 first year college students who did not meet criteria for a full or subthreshold eating disorder diagnosis at Time 1 (age M = 18.15; SD = 0.42; 122 female [46%] at Time 1) completed reports of compulsive exercise and eating disorder symptoms via online questionnaires at four timepoints over the 9-month 2021-2022 academic year (76% retention rate). Hypotheses were tested using a bivariate latent change score model. Hypotheses were not supported. Change in compulsive exercise did not predict change in number of eating disorder symptoms. Change in number of eating disorder symptoms also did not predict change in compulsive exercise. Compulsive exercise did not emerge as a variable risk factor for the development of eating disorder symptoms among first year college students. The relationship between these behaviors should be investigated at different developmental timepoints, such as early adolescence, and potential third variables that may explain the observed co-occurrence should be explored. This study investigated whether increases in compulsive exercise predicted increases in number of eating disorder symptoms among first year college students. Compulsive exercise did not significantly predict number of eating disorder symptoms. Additional research is warranted to clarify the relationship between compulsive exercise and eating disorder symptoms.

Assessing Temperament Risk Factors in Late Childhood and Early Adolescence: Development and Validation of the Integrative Late Childhood Temperament Inventory.

Childhood temperament has a well-documented influence on later life outcomes, notably behavior problems, quality of interpersonal relationships, and academic achievement. However, there is at present a lack of brief measures that assess temperament characteristics which are represented across models of temperament in the late childhood and early adolescence period. To redress this gap, the aim of the current study was to develop and validate a short questionnaire that extends an earlier integrative measure of temperament, the Integrative Child Temperament Inventory (ICTI) to the late childhood period. The new measure (named Integrative Late Childhood Temperament Inventory, ILCTI) includes all five components of the ICTI (frustration, behavioral inhibition, attention/persistence, activity level, sensory sensitivity), plus affiliation. German- or English-speaking parents rated a total of 525 children, aged 8 to 14years. Confirmatory factor analyses supported the predicted structure of the new measure. Examination of fit indices and psychometric analyses showed that 24 items are sufficient to capture all six dimensions reliably. Next to convergent validity with established measures of temperament and personality, we also present analyses of associations with measures of externalizing problems, internalizing problems, and school failure all of which support the instrument's clinical utility. Thus, despite its brevity, the ILCTI is a reliable and valid measure of late childhood temperament that can be helpful in assessing risk of developing behavior problems or school failure.

Age and sex Differences in Pediatric Neuropathic Pain and Complex Regional Pain Syndrome: A Scoping Review.

Age and sex differences may exist in the frequency (incidence, prevalence) or symptoms of neuropathic pain (NP) and complex regional pain syndrome (CRPS) due to biopsychosocial factors (e.g., neurodevelopment, physiological and hormonal changes, psychosocial differences) that evolve through childhood and adolescence.2 Age and sex differences may have implications for evaluating screening and diagnostic tools and treatment interventions. To map the existing literature on pediatric NP and CRPS with respect to age and sex distributions, and age and sex differences in symptomology and frequency. A scoping literature review was conducted. Databases were searched from inception to January 2023. Data were collected on study design, setting, demographics, and age and sex differences in frequency and symptoms. Eighty-seven studies were included. Distribution of participants with CRPS (n=37 studies) was predominantly early adolescence (10-14 years) and female sex, while NP (n=42 studies) was most commonly reported throughout adolescence (10-19 years) in both sexes. Forty-one studies examined age and sex differences in frequency; 6 studies reported higher frequency in adolescence. Very few studies (n=11) examined differences in symptomology. Large epidemiological studies are required to further understand age and sex differences in frequency of pediatric NP and CRPS. Age and sex differences must be considered when evaluating screening and diagnostic tools and treatment interventions to ensure relevance and validity to both sexes and across ages. Validated tools will improve understanding of age- and sex-dependent differences in symptoms, pathophysiology, and psychosocial impact of pediatric NP and CRPS.

How maternal and paternal parenting behaviors predict developmental changes in self-control and deviance during early adolescence

PurposeThe present study tested the pattern of developmental changes in self-control during early adolescence, and whether maternal and paternal closeness, support, monitoring, and disciplinary inconsistency were associated with developmental changes in deviance, indirectly through developmental changes in self-control. MethodsFive assessments part of the Brno Longitudinal Study of Youth on 582 early adolescents (58.4% female; Mage = 12.34 years, SD = 0.89 at baseline) were used for the study. A latent growth model tested the growth of self-control over two years in early adolescence. Associations between parenting and developmental changes in self-control as well as deviance were tested using structural equation modeling with latent constructs. ResultsSelf-control declined over time; individuals varied both in initial levels and rates of change. Full mediation through developmental changes in self-control were found; more specifically, more maternal monitoring at age 12 was associated with increases in self-control at age 13, which, in turn, was associated with less deviance at age 14. Results also provided evidence of direct effects, where more maternal closeness at age 12 was associated with less deviance at age 14. ConclusionsSelf-control decreased during early adolescence, thus supporting continued malleability. Both maternal closeness and monitoring were associated with less deviance, where the effect of monitoring was mediated through self-control.

The relationship between type, timing and duration of exposure to adverse childhood experiences and adolescent self-harm and depression: findings from three UK prospective population-based cohorts.

Adverse childhood experiences (ACEs) are well-established risk factors for self-harm and depression. However, despite their high comorbidity, there has been little focus on the impact of developmental timing and the duration of exposure to ACEs on co-occurring self-harm and depression. Data were utilised from over 22,000 children and adolescents participating in three UK cohorts, followed up longitudinally for 14-18 years: the Avon Longitudinal Study of Parents and Children (ALSPAC), the Millennium Cohort Study (MCS) and the Environmental Risk (E-Risk) Longitudinal Twin Study. Multinomial logistic regression models estimated associations between each ACE type and a four-category outcome: no self-harm or depression, self-harm alone, depression alone and self-harm with co-occurring depression. A structured life course modelling approach was used to examine whether the accumulation (duration) of exposure to each ACE, or a critical period (timing of ACEs) had the strongest effects on self-harm and depression in adolescence. The majority of ACEs were associated with co-occurring self-harm and depression, with consistent findings across cohorts. The importance of timing and duration of ACEs differed across ACEs and across cohorts. For parental mental health problems, longer duration of exposure was strongly associated with co-occurring self-harm and depression in both ALSPAC (adjusted OR: 1.18, 95% CI: 1.10-1.25) and MCS (1.18, 1.11-1.26) cohorts. For other ACEs in ALSPAC, exposure in middle childhood was most strongly associated with co-occurring self-harm and depression, and ACE occurrence in early childhood and adolescence was more important in the MCS. Efforts to mitigate the impact of ACEs should start in early life with continued support throughout childhood, to prevent long-term exposure to ACEs contributing to risk of self-harm and depression in adolescence.

Childhood obesity's influence on socioeconomic disparities in young adolescents’ mental health

PurposeWe investigated whether socioeconomic inequalities in young adolescents’ mental health are partially due to the unequal distribution of childhood obesity across socioeconomic positions (SEP), i.e. differential exposure, or due to the effect of obesity on mental health being more detrimental among certain SEPs, i.e. differential impact. MethodsWe studied 4660 participants of the Generation R study, a population-based study in the Netherlands. SEP was estimated by mother’s education and household income at age five of the child. We estimated the contribution of the mediating and moderating effects of high body fat percentage to the disparity in mental health. This was done through a four-way decomposition using marginal structural models with inverse probability of treatment weighting. ResultsComparing children with the least to most educated mothers and the lowest to highest household income, the total disparity in emotional problems was 0.98 points (95%CI:0.35–1.63) and 1.68 points (95%CI:1.13–2.19), respectively. Of these total disparities in emotional problems, 0.50 points (95%CI:0.15–0.85) and 0.24 points (95%CI:0.09–0.46) were due to the differential exposure to obesity. Obesity did not contribute to disparities in behavioural problems. ConclusionAddressing the heightened obesity prevalence among children in low SEP families may reduce inequalities in emotional problems in early adolescence.

Assessing causal links between age at menarche and adolescent mental health: a Mendelian randomisation study

BackgroundThe timing of puberty may have an important impact on adolescent mental health. In particular, earlier age at menarche has been associated with elevated rates of depression in adolescents. Previous research suggests that this relationship may be causal, but replication and an investigation of whether this effect extends to other mental health domains is warranted.MethodsIn this Registered Report, we triangulated evidence from different causal inference methods using a new wave of data (N = 13,398) from the Norwegian Mother, Father, and Child Cohort Study. We combined multiple regression, one- and two-sample Mendelian randomisation (MR), and negative control analyses (using pre-pubertal symptoms as outcomes) to assess the causal links between age at menarche and different domains of adolescent mental health.ResultsOur results supported the hypothesis that earlier age at menarche is associated with elevated depressive symptoms in early adolescence based on multiple regression (β = − 0.11, 95% CI [− 0.12, − 0.09], pone-tailed < 0.01). One-sample MR analyses suggested that this relationship may be causal (β = − 0.07, 95% CI [− 0.13, 0.00], pone-tailed = 0.03), but the effect was small, corresponding to just a 0.06 standard deviation increase in depressive symptoms with each earlier year of menarche. There was also some evidence of a causal relationship with depression diagnoses during adolescence based on one-sample MR (OR = 0.74, 95% CI [0.54, 1.01], pone-tailed = 0.03), corresponding to a 29% increase in the odds of receiving a depression diagnosis with each earlier year of menarche. Negative control and two-sample MR sensitivity analyses were broadly consistent with this pattern of results. Multivariable MR analyses accounting for the genetic overlap between age at menarche and childhood body size provided some evidence of confounding. Meanwhile, we found little consistent evidence of effects on other domains of mental health after accounting for co-occurring depression and other confounding.ConclusionsWe found evidence that age at menarche affected diagnoses of adolescent depression, but not other domains of mental health. Our findings suggest that earlier age at menarche is linked to problems in specific domains rather than adolescent mental health in general.

Exploring Features That Play a Role in Adolescents’ Science Identity Development

AbstractMany studies done in the last three decades show that, beginning with adolescence and sometimes even earlier, many adolescents undergo a process of distancing themselves from science as they age. This longitudinal study attempts to deepen our knowledge and understanding of factors that play a role in early adolescents’ science identity development. For 3 years, we followed nine early adolescents at school, at home, and at their after-school activities, interviewing them 162 times. A thematic analysis of the interviews led to the identification of 32 themes. When comparing these themes across different participants, we identified three motifs that distinguished between the participants. Our findings suggest that (A) having a clear area of interest, not necessarily in science, positively affected the participants’ self-efficacy in science and self-assessment of their ability in science studies; (B) being or not being the eldest child in a family with multiple siblings played a role in the participants’ identity development in relation to science; and (C) the participants who were wholly dependent on their grades as an indication of their ability in science rejected the possibility of a future in science and studied science out of compliance rather than out of any internal motive. The implications of our findings are discussed and offer insights into ways that may nurture the positive science identity development of early adolescents.

Family obligation moderates longitudinal associations between parental psychological control and adjustment of urban adolescents

This study investigated child-reported family obligation values (FOVs) in early adolescence as a moderator for associations between mother-, father-, and child-reported parental psychological control (PC) in early adolescence and child-reported internalizing and externalizing symptoms in middle and late adolescents in the Philippines. Data were drawn from three waves of a larger longitudinal study, when the Filipino youth were in late elementary grades (age M = 12.04, SD = 0.58; N = 91), in junior high school (age M = 15.03, SD = 0.59; N = 80), and in senior high school (age M = 17.00, SD = 0.59, N = 75). Results revealed that high levels of FOV buffered the positive associations between mother-reported PC and internalizing symptoms in late adolescence, and between child-reported PC and internalizing symptoms in middle and late adolescence, as well as externalizing symptoms in late adolescence. Conversely, low levels of FOV exacerbated the associations between mother- and child-reported PC on externalizing symptoms in late adolescence. Findings suggest that FOV may shape the meaning and influence of PC for children and adolescents in contexts where familial obligations are normative and important.

Network Position Affects Social Status in Early Adolescence

ABSTRACT Does position in the friendship network affect social status in early adolescence? Previous research shows that friendship relations are not equivalent to popularity hierarchies, but favorable positions in the friendship network should allow students to gain status. We use four waves of longitudinal network data and dynamic panel models with fixed effects to estimate the impact of network position on social status. Degree centrality and brokerage opportunity both exert large impacts on status, even compared against the effect of prior status. The results suggest future research on friendship across social identities, as well as network structure and hierarchy in adolescent social systems.

Examining neural responses to anticipating or receiving monetary rewards and the development of binge eating in youth. A registered report using data from the Adolescent Brain Cognitive Development (ABCD) study

Binge eating is characterized as eating a large amount of food and feeling a loss of control while eating. However, the neurobiological mechanisms associated with the onset and maintenance of binge eating are largely unknown. Recent neuroimaging work has suggested that increased responsivity within reward regions of the brain to the anticipation or receipt of rewards is related to binge eating; however, limited longitudinal data has precluded understanding of the role of reward responsivity in the development of binge eating. The current study used data from the Adolescent Brain and Cognitive Development® (ABCD) longitudinal study dataset to assess whether heightened neural responses to different phases of reward processing (reward anticipation and receipt) (1) differentiated individuals with binge eating from matched controls, and (2) predicted the onset of binge eating in an "at risk" sample. Consistent with hypotheses, heightened neural responsivity in the right caudate and bilateral VS during reward anticipation differentiated youth with and without binge eating. Moreover, greater VS response to reward anticipation predicted binge eating two years later. Neural responses to reward receipt also were consistent with hypotheses, such that heightened VS and OFC responses differentiated youth with and without binge eating and predicted the presence of binge eating two years later. Findings from the current study suggest that hypersensitivity to rewards may contribute to the development of binge eating during early adolescence.

Longitudinal Associations between Metacognition and Spontaneous and Deliberate Mind Wandering During Early Adolescence.

Although metacognition plays a pivotal role in theoretical accounts of mind wandering, their longitudinal relationships have not yet been investigated during the important developmental period of early adolescence. This study aimed to examine the developmental trajectories of spontaneous and deliberate mind wandering and the dynamic associations between metacognition and two types of mind wandering in early adolescence. A sample of 4302 Chinese students beginning in Grade 4 (47.4% female; initial Mage = 9.84, SDage = 0.47) completed questionnaires on five occasions over 2.5 years. The results showed that deliberate mind wandering, but not spontaneous mind wandering, gradually increased from Grade 4 to Grade 6. Metacognition was negatively related to spontaneous mind wandering but positively related to deliberate mind wandering. These findings provide empirical evidence for theoretical viewpoints from both individual differences and developmental perspectives.

A case study in developmental discontinuity: PROSPER Interventions and adolescent substance use trajectories shape young adult substance use and mental health problems.

The loss of John Schulenberg reverberates across the developmental and prevention sciences. In honor of his many contributions, this paper applies his ideas of developmental continuity and discontinuity to understand the process by which PROSPER delivered universal prevention programs (delivered in Grades 6 and 7) affect young adult outcomes. Guided by these developmental models, we deconstructed adolescent substance use initiation trajectories into two discrete phases-early and late adolescence, demarcated by substance use initiation levels at the end of 9th grade. We evaluated the effects of PROSPER interventions on these phases, and in turn, the effects of adolescent substance use initiation on young adult antisocial behavior, alcohol and drug use consequences, and depression symptoms. This sample included 1,984 young adults who participated in the PROSPER intervention trial in Grade 6 (two cohorts, 2002 and 2003), followed over 8 adolescent measurement occasions (Fall and Spring of Grade 6; Spring of Grades 7-12). Young adult outcomes were averaged across three waves (collected at ages 20, 23, and 25). PROSPER interventions were associated with reduced substance use initiation in early adolescence, but not escalation during late adolescence. In turn, substance use in both early and late adolescence was uniquely associated with young adult antisocial behavior, depression symptoms, and substance use consequences. PROSPER interventions were associated with young adult antisocial behavior and problematic substance use via reduced risk for early initiation status. Findings are discussed in terms of developmental continuity and discontinuity.
