An Ecological Analysis of the Effects of Deviant Peer Clustering on Sexual Promiscuity, Problem Behavior, and Childbearing from Early Adolescence to Adulthood: An Enhancement of the Life History Framework

The authors propose that peer relationships should be included in a life history perspective on adolescent problem behavior. Longitudinal analyses were used to examine deviant peer clustering as the mediating link between attenuated family ties, peer marginalization, and social disadvantage in early adolescence and sexual promiscuity in middle adolescence and childbearing by early adulthood. Specifically, 998 youths, along with their families, were assessed at age 11 years and periodically through age 24 years. Structural equation modeling revealed that the peer-enhanced life history model provided a good fit to the longitudinal data, with deviant peer clustering strongly predicting adolescent sexual promiscuity and other correlated problem behaviors. Sexual promiscuity, as expected, also strongly predicted the number of children by ages 22-24 years. Consistent with a life history perspective, family social disadvantage directly predicted deviant peer clustering and number of children in early adulthood, controlling for all other variables in the model. These data suggest that deviant peer clustering is a core dimension of a fast life history strategy, with strong links to sexual activity and childbearing. The implications of these findings are discussed with respect to the need to integrate an evolutionary-based model of self-organized peer groups in developmental and intervention science.

Parent-child relationships, partner relationships, and emotional adjustment: a birth-to-maturity prospective study.

This study examined whether detrimental childhood relationships with parents were related to partner relationship quality and emotional adjustment in adulthood. The authors tested a theoretical model in which (a) low-quality parent-child relationships were related to conflict and low-quality communication with parents in adolescence, (b) parent-adolescent conflict and low-quality communication were linked to low-quality partner relationships in young adulthood, and (c) low-quality partner relationships in young adulthood were predictive of low-quality partner relationships as well as depression, anxiety, and dissatisfaction with life at midlife. Multi-informant data were used from 212 Swedish individuals who were followed from birth into adulthood. Results demonstrated that, as hypothesized, negative parent-child bonds were indirectly related to low-quality partner relationships and dissatisfaction with life in adulthood (but not anxiety and depression) through conflictual parent-adolescent communication and low-quality partner relationships in young adulthood.

Emotion Regulation in Adolescence: A Prospective Study of Expressive Suppression and Depressive Symptoms

Cross-sectional studies have shown a positive association between expressive suppression and depressive symptoms. These results have been interpreted as reflecting the impact of emotion regulation efforts on depression. However, it is also possible that depression may alter emotion regulation tendencies. The goal of the present study was to prospectively examine the bidirectional association between habitual use of suppression and depressive symptoms in young adolescents. Participants were 1,753 adolescents (mean age = 13.8 years) who reported their use of suppression and depressive symptoms at two time points with a 1-year interval. Suppression and depressive symptoms were correlated within each time point. Depressive symptoms preceded increased use of suppression 1 year later, but suppression did not precede future depressive symptoms. Overall, the findings suggest depressive symptoms may be a potential precursor of habitual use of suppression during adolescence.

Effects of attractiveness and social status on dating desire in heterosexual adolescents: an experimental study.

The present study examined to what extent adolescent dating desire is based on attractiveness and social status of a potential short-term partner. Further, we tested whether self-perceived mate value moderated the relationship between dating desire and attractiveness of a potential partner. Data were used from a sample of 1,913 adolescents aged 13–18. Participants rated the importance of various characteristics of a potential partner and also participated in an experimental vignette study in which dating desire was measured with either low or high attractive potential partners having either a high or low social status. The results showed that boys rated attractiveness as more important than girls, while social status was rated as relatively unimportant by both sexes. In addition, in the experimental vignette study, it was found that attractiveness was the primary factor for boys’ dating desire. Only when a potential partner was attractive, social status became important for boys’ dating desire. For girls, on the other hand, it appeared that both attractiveness and social status of a potential partner were important for their dating desire. Finally, boys and girls who perceived themselves as having a high mate value showed more dating desire toward an attractive potential partner compared to adolescents who perceived themselves as having a low mate value. The present results extend previous research by showing that attractiveness of a potential partner is important to both adolescent boys and girls, but social status does not strongly affect dating desire during this particular age period.

The importance of relationships with parents and best friends for adolescents’ romantic relationship quality: Differences between indigenous and ethnic Dutch adolescents:

This study examined how the quality of relationships with parents and friends were related to intimacy, commitment, and passion in adolescents’ romantic relationships for indigenous Dutch and ethnic Dutch adolescents. Self-report survey data were used from 444 (88.9%) indigenous Dutch and 55 (11.1%) ethnic Dutch adolescents between 12 and 18 years of age (M = 15.34, SD = 1.14), all of whom were involved in a romantic relationship. About 61.6% (n = 307) were girls. For both indigenous and ethnic Dutch youths, the quality of the parent—adolescent relationship was positively associated with romantic relationship intimacy, whereas the quality of one’s best friendship was related to higher commitment to one’s romantic partner. Significant interactions in hierarchical regression analyses revealed that only ethnic Dutch adolescents who experienced low-quality parent—adolescent relationships showed more commitment to their romantic relationships. Additionally, ethnic Dutch adolescents who experienced low-quality best friendships showed more passion in their romantic relationships as compared to indigenous Dutch adolescents. These findings are indicative of ethnic differences in the roles that parents and friends play in the romantic lives of Dutch adolescents.

Do Conflict Resolution and Recovery Predict the Survival of Adolescents' Romantic Relationships?

Numerous studies have shown that being able to resolve and recover from conflicts is of key importance for relationship satisfaction and stability in adults. Less is known about the importance of these relationship dynamics in adolescent romantic relationships. Therefore, this study investigated whether conflict resolution and recovery predict breakups in middle adolescent couples. Couples who are able to resolve and recover from conflict were expected to demonstrate a lower probability of breaking up. In total, 80 adolescent couples (M age = 15.48, SD = 1.16) participated in a 4-wave prospective questionnaire and observational study, with one year between measurements. In addition to self-report measures, adolescents were observed in real-time during conflicts with their partners. Multilevel Proportional Hazard analyses revealed that, contrary to the hypothesis, conflict resolution and conflict recovery did not predict the likelihood of breakup. Survival differences were not attributable to conflict resolution or conflict recovery. More research is needed to consider the unique relationship factors of adolescent romantic relationships to determine why some relationships survive while others do not.

Loneliness in the daily lives of young adults : Testing a socio-cognitive model

A socio–cognitive model of loneliness states that lonely people are characterized by two characteristics, hypersensitivity to social threat and hyposensitivity to social reward. However, these characteristics have not yet been examined in the daily lives of young adults. Therefore, the main aim of the present study was to examine these two characteristics in young adults and whether relationship status, living situation, and type of company moderated the relationship between sensitivity to threat and reward and feelings of loneliness. The Experience Sampling Method was used, and data were collected among 219 first–year college students (M age = 19.60, 91% female). Participants filled out questionnaires on their smartphone at five random time points per day, on 11 consecutive days. Multilevel analyses showed support for hypersensitivity to social threat, in that students high in loneliness were more negatively affected by negative perceptions of company. Results for hyposensitivity to social reward were in the opposite direction; students high in loneliness were more positively affected by positive perceptions of company than students low in loneliness. These relations were not moderated by relationship status or living situation. Our findings may indicate that loneliness serves as a motivational state that increases susceptibility to the environment in order to restore social relationships. Copyright

Adiponectin: Serum-saliva associations and relations with oral and systemic markers of inflammation

&NA; This study addresses gaps in our understanding about the validity and utility of using salivary adiponectin to index serum adiponectin levels. Matched blood and saliva samples were collected on a single occasion from healthy adults (n = 99; age 18–36 years, 53% male). Serum and saliva was assayed for adiponectin and inflammatory cytokines (IL‐1&bgr;, IL‐6, IL‐8, TNF&agr;), and saliva was also assayed for markers of blood contamination (transferrin), total protein (salivary flow rate) and matrix metalloproteinase‐8 (MMP‐8). We examined the extent to which salivary adiponectin was associated with serum adiponectin, and the influence of potential confounders on the serum‐saliva correlation, including age, sex, body mass index, and markers of inflammation, oral health, salivary blood contamination, and flow rate. Findings revealed a modest serum‐saliva association for adiponectin, and strong positive associations between salivary adiponectin and salivary levels of inflammatory cytokines, MMP‐8, transferrin, and total protein. By contrast, salivary adiponectin was not related to serum levels of inflammatory activity. The magnitude of the serum‐saliva association was strengthened when controlling for total protein in saliva, blood leakage into oral fluid, salivary inflammatory cytokines, and MMP‐8. The pattern of findings extends our understanding of salivary adiponectin and its potential use as an index of circulating adiponectin levels. HighlightsSalivary adiponectin was positively correlated with salivary inflammatory activity.Salivary and serum adiponectin were not related to serum inflammatory activity.Serum and salivary adiponectin were moderately positively correlated.Adjusting for oral inflammation improved the adiponectin serum‐saliva correlation.

Observed Family and Friendship Dynamics in Adolescence: a Latent Profile Approach to Identifying “Mesosystem” Adaptation for Intervention Tailoring

Nuanced understanding of adolescents’ interpersonal relationships with family and peers is important for developing more personalized interventions that prevent problem behaviors and adjustment issues. We used latent profile analysis (LPA) to classify a community sample of 784 adolescents with respect to their observed relationship dynamics with friends and family using videotaped observations and five-minute audiotaped speech samples collected at ages 16–17. The resulting latent classes served to predict behavioral and emotional health in early adulthood. The LPA of the video- and audio-coded observational variables revealed a three-class model: (1) the healthy relationship group (n = 587), representing low levels of deviant and drug use talk with friends and positive, noncoercive relationship with parents; (2) the disaffected group (n = 90), representing high levels of drug use talk with friends and negativity about their parent(s) in the five-minute speech sample; and (3) the antisocial group (n = 107), representing high levels of deviant talk, drug use talk, coercive joining with friends, and coerciveness in family interactions. In contrast to the healthy relationship group, the disaffected group showed elevated risk for substance use problems and depression and the antisocial group showed higher risk for substance use problems and committing violent crimes in early adulthood. Outcome differences between disaffected and antisocial groups were mostly nonsignificant. We discuss the viability of applying these findings to tailoring and personalizing family-based interventions with adolescents to address key dynamics in the family and friendship relationships to prevent adult substance use problems, depression, and violence.

Dynamic responses in brain networks to social feedback: A dual EEG acquisition study in adolescent couples

Adolescence is a sensitive period for the development of romantic relationships. During this period the maturation of frontolimbic networks is particularly important for the capacity to regulate emotional experiences. In previous research, both functional magnetic resonance imaging (fMRI) and dense array electroencephalography (dEEG) measures have suggested that responses in limbic regions are enhanced in adolescents experiencing social rejection. In the present research, we examined social acceptance and rejection from romantic partners as they engaged in a Chatroom Interact Task. Dual 128-channel dEEG systems were used to record neural responses to acceptance and rejection from both adolescent romantic partners and unfamiliar peers (N = 75). We employed a two-step temporal principal component analysis (PCA) and spatial independent component analysis (ICA) approach to statistically identify the neural components related to social feedback. Results revealed that the early (288 ms) discrimination between acceptance and rejection reflected by the P3a component was significant for the romantic partner but not the unfamiliar peer. In contrast, the later (364 ms) P3b component discriminated between acceptance and rejection for both partners and peers. The two-step approach (PCA then ICA) was better able than either PCA or ICA alone in separating these components of the brains electrical activity that reflected both temporal and spatial phases of the brains processing of social feedback.
