Orbital frontal cortex functional connectivity during gain anticipation linking the rumination and non-suicidal self-injury in late adolescence

OBJECTIVE

Non-suicidal self-injury (NSSI) is prevalent and especially among the adolescence population. It has been argued that abnormal brain activations in reward processing could be regarded as objective biomarkers in NSSI, but the evidence is mixed. This study aims to explore the reward processing mechanism of NSSI from the perspective of functional brain circuitry and investigate the role of a cognitive factor (rumination).

METHOD

Seventy-one 17-21 years old participants performed a monetary incentive delay (MID) task during functional magnetic resonance imaging scanning. Psychophysiological interaction (PPI) analysis was used to test the inner-group differences of brain functional connectivity. In addition, a mediation model was established with the mediation effect of rumination on the relationship between functional brain circuitry and NSSI.

RESULTS

PPI analysis suggested that functional connectivity of the orbital frontal cortex (OFC) (with precuneus, SMA) was significantly enhanced in NSSI in the gain > loss contrast, but not in the loss > gain contrast. Mediation analysis revealed that rumination mediated the relationship between NSSI and the OFC- precuneus functional connectivity in the gain > loss contrast.

CONCLUSION

Our research revealed that the abnormal OFC functional connectivity in gain (not loss) anticipation can be served as the sensitive biomarkers of NSSI. And there was a chain path for NSSI, that was from functional brain circuitry to negative cognition and then to problem behavior.

Sleep and Daily Affect and Risk for Major Depression: Day-to-day and Prospective Associations in Late Adolescence and Early Adulthood

PURPOSE

Poor sleep is associated with short-term dysregulation of mood and is a risk factor for major depressive disorder (MDD). This study examines whether objectively measured sleep in late adolescence prospectively predicts major depressive episode (MDE) onset in early adulthood as well as whether daily affect mediates this association.

METHODS

The present study draws on subjective and objective sleep data, ecological momentary assessment, and diagnostic data from the longitudinal Youth Emotion Project to examine whether: a) short sleep predicts dysregulated ecological momentary assessment-measured mood the next day; b) sleep predicts depressive episodes over the subsequent 5 years; and c) dysregulated daily moods mediate the associations between short sleep and later MDD. Fixed effects, logistic regression, and formal mediation analyses were employed.

RESULTS

Our results showed that nights with less sleep are followed by days with more negative affect; short sleep predicted MDEs over the subsequent 5 years (adjusting for prior MDD); and negative affect mediates the relationship between short sleep and later MDEs.

DISCUSSION

Overall, our findings show sleep to be an important risk factor and hence a promising point of intervention for improving mood and reducing the risk of future MDEs in adolescents and early adults.

Longitudinal Associations Between Depressive Symptoms and Quality of Romantic Relationships in Late Adolescence

While youth with higher levels of depressive symptoms appear to have lower quality romantic relationships, little is known about longitudinal associations for both men and women. Therefore, this study used longitudinal dyadic design to examine both concurrent and longitudinal associations between depressive symptoms and positive as well as negative aspects of romantic relationship quality across two waves one- or two-years apart. The sample consisted of 149 Dutch stable heterosexual couples (149 females and 142 males participated at T₁) in a stable romantic relationship in late adolescence with a mean age of 20.43 years old at the first wave. Actor-Partner Interdependence models were used to examine potential bidirectional associations over time between depressive symptoms and romantic relationship quality, above and beyond potential concurrent associations and stability of the constructs over time, from the perspective of both romantic partners. Results consistently indicated that men and women who reported higher levels of depressive symptoms perceived less positive aspects (intimacy and support) and more negative aspects (conflict) in their romantic relationship over time. In addition, unexpectedly, when men and women perceived more positive relationship aspects, their partners reported higher levels of depressive symptoms over time. These findings stress that depressive symptoms can interfere with the formation of high-quality romantic relationships.

Examining Device-Assessed Physical Activity During the Transition Into Emerging Adulthood: Results From the MovingU Study

PURPOSE

The purpose of the present study was to conduct the first longitudinal investigation using accelerometers to assess physical activity behavior change during individuals' acute transition out of high school.

METHODS

Participants in the current investigation were a part of a prospective cohort study called the MovingU Study. Participants were 163 adolescents (M_age = 16.9 ± .5; n = 88 females) recruited at the beginning of their final year at high school, with follow-up at 6 and 18 months. Participants wore the ActiGraph Link for 7 days at each assessment period.

RESULTS

Results from the mixed-effects models found no significant differences in moderate-to-vigorous physical activity or total physical activity between baseline and follow-up at 6 months (Estimates = 1.91 and -2.26, p's > .05), respectively; however, significant differences in both moderate-to-vigorous physical activity and total physical activity between baseline and follow-up at 18 months after the transition out of highschool (Estimate = -123.62 and -15.38, p's < .01).

CONCLUSIONS

Current findings provide additional compelling data to show precipitous declines in physical activity as adolescents transition out of high school and into emerging adulthood. Continued efforts to maintain or increase physical activity during adolescence and the prevention of physical activity declines as they enter emerging adulthood could have important public health benefits.

Social Withdrawal and Romantic Relationships: A Longitudinal Study in Early Adulthood

Involvement in romantic relationships is a salient developmental task in late adolescence and early adulthood, and deviations from normative romantic development are linked to adverse outcomes. This study investigated to what extent social withdrawal contributed to deviations from normative romantic development, and vice versa, and the interplay between withdrawal and couples’ relationship perceptions. The sample included 1710 young adults (55–61% female) from the Tracking Adolescents’ Individual Lives Survey cohort and their romantic partners. Data were collected across 4 waves, covering romantic relationships from ages 17 to 29 years. The results showed that higher withdrawal predicted a higher likelihood of romantic non-involvement by adulthood, consistently being single at subsequent waves, and entering one’s first relationship when older. Withdrawal moderately decreased when youth entered their first relationship. Male’s withdrawal in particular affected romantic relationship qualities and dynamics. These results provide new insights into the developmental sequelae of withdrawn young adults’ romantic relationship development.

["Klar bleiben" (keep a clear head)-a competition for school classes to reduce alcohol consumption]

In Germany, alcohol is the most popular drug among adolescents. So far, school-based alcohol prevention programs have focused on elementary school children and pupils in early adolescence. The school program "Klar bleiben" ("Keep a Clear Head") was especially designed for young people in late adolescence (10th graders) with the aim of establishing non-binge drinking as a social norm.Students in the participating classes commit themselves to abstain from binge drinking for six weeks (contract management). The class gives feedback after each week. After at least five positive feedbacks, the class is rated as successful and enters a prize draw. Elaborated teaching impulses and information resources for teachers and parents are further components of the prevention program.The evaluation of the class competition by 92 teachers can be regarded as consistently positive. The results of a cluster-randomized study showed a relative risk reduction of 10.4% in binge drinking in the last month for those adolescents who had already consumed alcohol before and belong to the intervention group. After the end of the intervention, this group of adolescents consumed an average of 0.19 fewer alcoholic beverages per drinking occasion compared to adolescents from the control group. The findings presented here are encouraging, keeping in mind that the intervention is relatively inexpensive.

Searching for Autonomy before the Transition to Higher Education: How do Identity and Self-Determined Academic Motivation Co-Evolve?

Identity and academic motivation are particularly at stake before the major transition to higher education. However, few studies have explored their changes and their longitudinal bidirectional links. To fill this gap, a three-wave study from the end of the 11th grade to the end of the 12th grade was conducted to explore changes in identity processes and academic motivation and to investigate how they might be interconnected over time. 599 adolescents (mean age 17.4; 59% girls) completed questionnaires containing measures about identity processes and three types of academic motivation: autonomous, controlled, and impersonal. Throughout the study span of one year, four identity processes increased: commitment making, identification with commitment, exploration in breadth and exploration in depth, while the process of ruminative exploration decreased. Simultaneously, late adolescents encountered an increase in impersonal motivation, more salient for boys. The results also revealed unidirectional links from motivation to identity processes, with no gender or age moderator effects: exploration in breadth and exploration in depth were positively predicted by autonomous motivation, ruminative exploration was positively predicted by autonomous, controlled, and impersonal motivation. In addition, impersonal motivation negatively predicted commitment making. On the other hand, identification with commitment positively predicted autonomous motivation. Practical implications are discussed.

Predicting hazardous drinking in late adolescence/young adulthood from early and excessive adolescent drinking - a longitudinal cross-national study of Norwegian and Australian adolescents

Background

Research has consistently shown that early onset of drinking (EOD) is associated with alcohol-related problems in adulthood. However, recent reviews have identified several limitations in the early onset literature, including the use of retrospective reports, insufficient control for potential confounders, ambiguous definitions of the concept, and an assumption that early onset is independent of cultural norms and national alcohol policies. This study addresses these limitations by examining whether EOD, independent of early onset of excessive drinking (EOE), prospectively predicts hazardous drinking in late adolescence/young adulthood in Norway and Australia, two countries with different drinking cultures.

Methods

Data were drawn from two population-based longitudinal studies; the Norwegian Tracking Opportunities and Problems Study (n = 329) and the Australian International Youth Development Study (n = 786). Data were collected prospectively from mid adolescence (14–16 years) to late adolescence/young adulthood (18–25 years) and a modified Poisson regression approach was used to estimate prevalence ratios. Adolescent self-reports included measures of EOD and EOE. Young adults completed the Alcohol Use Disorders Identification Test (AUDIT). The results were adjusted for adolescent factors; age, gender, impulsivity, hyperactivity, conduct problems, smoking, early sexual intercourse and friends’ substance use, and family factors; alcohol and drug use in the family, maternal education, family management and monitoring.

Results

Hazardous drinking was identified in 46.8 and 38.9% of young adults in Norway and Australia, respectively. Both EOD and EOE in adolescence were significantly related to an increased risk of alcohol-related problems in late adolescence/young adulthood in both studies, even when adjusting for possible confounders.

Conclusion

Our findings indicate that adolescent drinking behaviour is an indicator of alcohol-related problems in late adolescence/young adulthood, even when controlling for a variety of covariates. This finding is in contrast to previous research on older adults, where no association between adolescent drinking and later alcohol-related problems were found when controlling for covariates. The divergence in findings may suggest that the impact of EOD/EOE is limited to the late adolescent and young adult period. Preventing drinking in early adolescence may thus have some impact on the drinking patterns in late adolescence/young adulthood.

Revisiting the Link Between Depression Symptoms and High School Dropout: Timing of Exposure Matters

PURPOSE

Recent reviews concluded that past depression symptoms are not independently associated with high school dropout, a conclusion that could induce schools with high dropout rates and limited resources to consider depression screening, prevention, and treatment as low-priority. Even if past symptoms are not associated with dropout, however, it is possible that recent symptoms are. The goal of this study was to examine this hypothesis.

METHODS

In 12 disadvantaged high schools in Montreal (Canada), all students at least 14 years of age were first screened between 2012 and 2015 (N_screened = 6,773). Students who dropped out of school afterward (according to school records) were then invited for interviews about their mental health in the past year. Also interviewed were matched controls with similar risk profiles but who remained in school, along with average not at-risk schoolmates (N_interviewed = 545). Interviews were conducted by trained graduate students.

RESULTS

Almost one dropout out of four had clinically significant depressive symptoms in the 3 months before leaving school. Adolescents with recent symptoms had an odd of dropping out more than twice as high as their peers without such symptoms (adjusted odds ratio = 2.17; 95% confidence interval = 1.14-4.12). In line with previous findings, adolescents who had recovered from earlier symptoms were not particularly at risk.

CONCLUSIONS

These findings suggest that to improve disadvantaged youths' educational outcomes, investments in comprehensive mental health services are needed in schools struggling with high dropout rates, the very places where adolescents with unmet mental health needs tend to concentrate.

Latent classes of trait affect and cognitive affective regulation strategies are associated with depression, non-suicidal self-injury, and well-being

BACKGROUND

The present study sought to better understand the unique profiles of late adolescents' affective functioning by exploring patterns of trait affect and cognitive affective regulation strategies. The study also examined whether these unique profiles significantly predicted depressive symptoms, non-suicidal self-injury (NSSI), and well-being outcomes.

METHODS

Data from a sample of 590 late adolescents were examined (M = 19.14 years, SD = 1.41, 63% Female, 62% Caucasian, 38% African American/Biracial). Participants were followed for an average of 14 months (SD = 2.53) and completed measures of trait affect, cognitive affective regulation, depression, NSSI, and well-being. Data were examined using latent class analysis.

RESULTS

Five subgroups with unique patterns of affective functioning were identified. Late adolescents who reported above average levels of negative affect, dampening of positive affect, brooding, and reflection, coupled with below average levels of positive affect and positive rumination, were more likely to report having higher levels of depressive symptoms and greater engagement in NSSI during the one-year period prior to baseline. Similarly, the late adolescents fitting this profile also reported lower levels of well-being and were more likely to report engaging in NSSI at the follow-up.

LIMITATIONS

Limitations include a narrow exploration of affective regulation strategies and the addition of key variables after the initiation of the larger study.

CONCLUSIONS

These findings shed light on affective regulation factors relevant to the experience of depressive symptoms and NSSI, and the promotion of well-being.

When is Meaning in Life Most Beneficial to Young People? Styles of Meaning in Life and Well-Being Among Late Adolescents

The purpose of this article was to investigate the relationships between different dimensions of meaning in life and subjective and psychological well-being (PWB) among late adolescents. Three hundred and eighty four Polish participants completed The Personal Meaning Profile scale, The Satisfaction With Life Scale, The Positive and Negative Affect Schedule, The PWB scale, and the Meaning in Life Questionnaire. Two studies were conducted. In Study 1, the findings revealed that personal meaning had strong relations with subjective well-being (SWB) and PWB. In addition, the dimensions of personal meaning were more strongly associated with the cognitive dimension of SWB than with PWB. In Study 2, search for meaning had positive associations with SWB and PWB among those late adolescents who already had substantial meaning in life. Individuals who were in presence and search style had higher levels of SWB and PWB than those in only search style or presence style. The results demonstrate that purpose embedded in the concept of meaning in life appears central to the formation of adolescent well-being as young people come to establish overarching aims.

Boys vs. girls: Gender differences in the neural development of trust and reciprocity depend on social context

Trust and cooperation increase from adolescence to adulthood, but studies on gender differences in this development are rare. We investigated gender and age-related differences in trust and reciprocity and associated neural mechanisms in 43 individuals (16-27 years, 22 male). Participants played two multi-round trust games with a cooperative and an unfair partner. Males showed more basic trust towards unknown others than females. Both genders increased trust during cooperative interactions, with no differences in average trust. Age was unrelated to trust during cooperation. During unfair interactions males decreased their trust more with age than females. ROI analysis showed age-related increases in activation in the temporo-parietal junction (TPJ) and dorsolateral prefrontal cortex (dlPFC) during cooperative investments, and increased age-related caudate activation during both cooperative and unfair repayments. Gender differences in brain activation were only observed during cooperative repayments, with males activating the TPJ more than females, and females activating the caudate more. The findings suggest relatively mature processes of trust and reciprocity in the investigated age range. Gender differences only occur in unfair contexts, becoming more pronounced with age. Largely similar neural activation in males and females and few age effects suggest that similar, mature cognitive strategies are employed.

Emotion socialization as a predictor of physiological and psychological responses to stress

Reactivity patterns to acute stress are important indicators of physical and mental health. However, the relationships between emotion socialization and stress responses are not well understood. This study aimed to examine whether parental responses to negative emotions predicted physiological and psychological responses to acute stress in late adolescence and emerging adulthood, and whether these relationships varied by gender and ethnicity. Participants were 973 individuals (mean age=19.20years; 50% male; 63% African American, 34% European American) who reported on parental emotion socialization. Participants completed a standardized social stress test (the Trier Social Stress Test; TSST). Heart rate, blood pressure and salivary samples were assessed from baseline throughout the task and during recovery period. Psychological responses to stress were measured immediately after the TSST. Unsupportive parental responses to children's negative emotions were associated with blunted cortisol reactivity and greater negative emotions to a psychosocial stress task in females and African American youth, whereas supportive parental responses predicted greater cortisol reactivity and lower negative emotions to stress in European American youth, as well as less negative emotions in males. However, parental responses to negative emotions did not predict heart rate or SBP reactivity to the TSST. Findings suggest that parental emotion socialization may be an important factor influencing HPA axis reactivity and psychological responses to stress, with important differences across gender and ethnic youth subgroups.

Traumatic experiences, alexithymia, and Internet addiction symptoms among late adolescents: A moderated mediation analysis

The association between traumatic experiences, alexithymia, and substance abuse is well established. Less is known about the role of traumatic experiences and alexithymia in the onset and maintenance of Internet-related disorders. In the present study, self-report measures on traumatic experiences, alexithymia, and problematic Internet use were administered to 358 high school students (57% females) aged 18-19years old, to test whether alexithymic traits mediated the relationship between traumatic experiences and Internet addiction symptoms, and whether gender moderated the proposed mediation in the sample. While partial mediation occurred in the entire sample, gender directly affected the relationship between the investigated constructs: Internet addiction symptoms were independently related to traumatic experiences among males, and to alexithymic traits among females. Therefore, the results of this study suggest that trauma memories among males, and problems with affect regulation among females, may increase the risk of problematic Internet use during late adolescence. Such findings might have relevant implications to inform any treatment plan for late adolescent students who are overinvolved with online activities, pointing out that tailored approaches to their problems and difficulties are particularly needed in clinical practice.

Friendship networks and psychological well-being from late adolescence to young adulthood: a gender-specific structural equation modeling approach

BACKGROUND

The importance of supportive social relationships for psychological well-being has been previously recognized, but the direction of associations between both dimensions and how they evolve when adolescents enter adulthood have scarcely been addressed. The present study aims to examine the gender-specific associations between self-reported friendship network quality and psychological well-being of young people during the transition from late adolescence to young adulthood by taking into account the direction of association.

METHODS

A random sample of Swedes born in 1990 were surveyed at age 19 and again at age 23 regarding their own health and their relationships with a maximum of five self-nominated friends. The response rate was 55.3 % at baseline and 43.7 % at follow-up, resulting in 772 cases eligible for analysis. Gender-specific structural equation modeling was conducted to explore the associations between network quality and well-being. The measurement part included a latent measure of well-being, whereas the structural part accounted for autocorrelation for network quality and for well-being over time and further examined the cross-lagged associations.

RESULTS

The results show that network quality increased while well-being decreased from age 19 to age 23. Females reported worse well-being at both time points, whereas no gender differences were found for network quality. Network quality at age 19 predicted network quality at age 23, and well-being at age 19 predicted well-being at age 23. The results further show positive correlations between network quality and well-being for males and females alike. The strength of the correlations diminished over time but remained significant at age 23. Simultaneously testing social causation and social selection in a series of competing models indicates that while there were no cross-lagged associations among males, there was a weak reverse association between well-being at age 19 and network quality at age 23 among females.

CONCLUSIONS

The study contributes to the understanding of the direction of associations between friendship networks and psychological well-being from late adolescence to young adulthood by showing that while these dimensions are closely intertwined among males and females alike, females' social relationships seem to be more vulnerable to changes in health status.

Exploration of a novel object in late adolescence predicts novelty-seeking behavior in adulthood: Associations among behavioral responses in four novelty-seeking tests

The sensation/novelty seeking behavioral trait refers to the exploration/preference for a novel environment. Novelty seeking increases during late adolescence and it has been associated with several neurobehavioral disorders. In this experiment, we asked whether inbred Roman high- and low-avoidance (RHA-I, RLA-I) rats (1) differ in novelty seeking in late adolescence and (2) whether late adolescent novelty seeking predicts this trait in adulthood. Thirty six male RHA-I and 36 RLA-I rats were exposed to a novel object exploration (NOE) test during late adolescence (pnd: 52-59;

DEPENDENT VARIABLES

contact latency, contact time, contact frequency). Head-dipping (hole-board, HB), time and visits to a novel-arm (Y-maze), and latency-in and emergence latency (emergence test) were registered in adulthood (pnd: 83-105). The results showed strain differences in all these tests (RHA-I>RLA-I). Factor analysis (RHA-I+RLA-I) revealed two clusters. The first one grouped HB and emergence test measures. The second one grouped NOE and Y-maze variables. Time exploring a novel object (NOE) was a significant predictor of novel arm time (RHA-I+RLA, RHA-I); contact latency was a significant predictor of novel arm frequency (RLA-I). Present results show consistent behavioral associations across four novelty-seeking tests and suggest that late adolescent novelty seeking predicts this genetically-influenced temperamental trait in adult Roman rats.

Perspective Taking Explains Gender Differences in Late Adolescents' Attitudes Toward Disadvantaged Groups

Adolescents' attitudes toward disadvantaged groups are surprisingly understudied. What we know from these few studies is that adolescents' attitudes tend to become more favorable over time and that adolescent girls display more favorable attitudes than do adolescent boys. However, researchers have not offered explanations for why these effects occur. We proposed that changes in social-cognitive abilities that accompany adolescent development increase perspective taking and that the increased perspective taking facilitates more favorable attitudes toward disadvantaged groups. Because girls develop social-cognitive abilities earlier than boys, girls should show greater perspective taking and thus more positive attitudes toward disadvantaged groups than should boys. Importantly, we propose that these more positive attitudes are explained better by perspective taking than by gender. Participants were late adolescents (n = 803, 53.3 % female, ages 15-19) from high schools in north-central Florida (United States) participating in an ongoing, multi-wave study. Participants completed a measure of perspective-taking and reported their attitudes toward three disadvantaged groups (Black, gay, and poor people) during their third year of high school and, again, 6 months later during their fourth year of high school. Our findings provided strong support for our theorizing. Girls generally reported warmer attitudes than did boys toward disadvantaged groups, with the gender differences in warmth tending to diminish across time. Similarly, girls were higher than boys in perspective-taking abilities at both time points, although boys increased over time whereas girls did not. Crucially, perspective taking mediated observed gender differences in attitudes, suggesting that perspective taking is a mechanism for improving attitudes toward disadvantaged groups during late adolescence.

Alcohol use severity and depressive symptoms among late adolescent Hispanics: Testing associations of acculturation and enculturation in a bicultural transaction model

Research has indicated that Hispanics have high rates of heavy drinking and depressive symptoms during late adolescence. The purpose of this study was to test a bicultural transaction model composed of two enthnocultural orientations (acculturation and enculturation); and stressful cultural transactions with both the U.S. culture (perceived ethnic discrimination) and Hispanic culture (perceived intragroup marginalization) to predict alcohol use severity and depressive symptoms among a sample of 129 (men=39, women=90) late adolescent Hispanics (ages 18-21) enrolled in college. Results from a path analysis indicated that the model accounted for 18.2% of the variance in alcohol use severity and 24.3% of the variance in depressive symptoms. None of the acculturation or enculturation domains had statistically significant direct effects with alcohol use severity or depressive symptoms. However, higher reports of ethnic discrimination were associated with higher reports of alcohol use severity and depressive symptoms. Similarly, higher reports of intragroup marginalization were associated with higher depressive symptoms. Further, both ethnic discrimination and intragroup marginalization functioned as mediators of multiple domains of acculturation and enculturation. These findings highlight the need to consider the indirect effects of enthnocultural orientations in relation to health-related outcomes.
