Diseases of despair in early adulthood: The complex role of social relationships.

"Diseases of despair," most prominently depressive and substance-related problems, diminish the prospects of many young adults, especially those with lower levels of education. Yet many young adults in that situation avoid these problems. Close relationships are thought to be a key factor underpinning risk and resilience among this group. To examine this premise, this study explored links, beyond potential confounders assessed in adolescence, between strengths and strains in the social domain and markers of despair in the early and mid-20s in a Canadian sample overrepresenting youth without postsecondary credentials (N = 543, 52% male, 23% non-White). Having a good general ability to maintain supportive relationships was associated with fewer depressive and substance-related symptoms. Furthermore, support and less strain in relationships with parents and friends were associated with fewer depressive symptoms in the early and mid-20s, while for romantic relationships, associations with depressive symptoms became more consistent and robust in the mid-20s. Therefore, support and strains in romantic relationships gradually gained prominence as a determinant of depressive symptoms as youth advanced in adulthood. For substance-related problems, significant associations emerged for strains in friendships only, in both the early and mid-20s. These results suggest that multiple aspects of relationships pose a risk for or protect from the development of diseases of despair in early adulthood and that their relative importance changes depending on outcomes and developmental timing. Thus, facilitating meaningful social connections and reducing the prevalence and impact of relationship strains might contribute to preventing diseases of despair among youth with lower educational attainment.

Student Engagement as a Mediator Process Between Peer Victimization and Achievement at the Beginning of Middle School.

BACKGROUND: Very few studies have properly identified how peer victimization is associated with lower achievement in middle or high school. In this context, this study examined how peer victimization at the beginning of middle school is linked with subsequent student achievement. Specifically, it assessed if the behavioral, affective, and cognitive dimensions of engagement in school play a mediation role in the relationship between peer victimization and student achievement. METHODS: The sample of this study included 683 seventh graders attending 3 schools in Montreal, Canada. Students self-reported peer victimization at the beginning and end of grade 7. They also reported their levels of student engagement on the 3 dimensions (behavioral, affective, and cognitive) across 3 time points in seventh and eighth grades. Student achievement in language arts across these 2 years was also obtained through school records. RESULTS: Peer victimization significantly predicted lower achievement over time (b = -.24, p ≤ .001). Peer victimization predicted lower achievement in grade 8 indirectly through affective student engagement (b = -.11, p < .05). Post hoc analyses showed that peer victimization still predicted lower achievement in grade 8 indirectly through a decrease in affective engagement (b = -.14, p < .05). However, when considered alone, a decrease in cognitive engagement also acted as a mediator (b = -.09, p < .05), suggesting a strong link with affective engagement. CONCLUSION: Our findings expose the importance to promote student engagement in school and achievement for victimized youth.

Interplay between peer experiences and classroom behavioral engagement throughout early childhood: Intraindividual and interindividual differences.

Developmental theorists emphasize the existence of reciprocal influences between children's peer experiences and their early classroom behavioral engagement. For school practitioners who must identify relevant intervention targets to design educational activities, estimating precisely how aspects of peer experiences and behavioral engagement jointly unfold over time is of key interest. In addition, it is important to differentiate between intraindividual and interindividual effects. Nevertheless, evidence of these reciprocal links or intra- and interindividual effects during the early stages of schooling is scarce. This study (N = 638 children) used a Latent Curve Model with Structured Residuals (LCM-SR) to disentangle interindividual differences (stable trait-like) from intraindividual changes (dynamic state-like) in the associations between peer experiences (social acceptance and friendship involvement) and children's classroom behavioral engagement from the beginning of kindergarten through Grade 2. Results indicated that the links between children's peer experiences and their behavioral engagement reflect their steady tendency to be well adjusted in the classroom as well as with peers, rather than highlighting reciprocal associations between these factors over time. However, results also underscored that children who showed high engagement tended to be concurrently more accepted by peers in the same school year in Grade 1 or Grade 2, beyond stable aspects of engagement and social acceptance. These findings support the need to develop educational practices to improve social acceptance as a way to foster behavioral engagement. They also indicate that behavioral engagement should be considered a concrete intervention target for school practitioners seeking to improve children's social acceptance during the school year.

A Test of the Bistrategic Control Hypothesis of Adolescent Popularity.

Resource Control Theory (Hawley, 1999) posits a group of bistrategic popular youth who attain status through coercive strategies while mitigating fallout via prosociality. This study identifies and distinguishes this bistrategic popular group from other popularity types, tracing the adjustment correlates of each. Adolescent participants (288 girls, 280 boys; Mage  = 12.50 years) completed peer nominations in the Fall and Spring of the seventh and eighth grades. Longitudinal latent profile analyses classified adolescents into groups based on physical and relational aggression, prosocial behavior, and popularity. Distinct bistrategic, aggressive, and prosocial popularity types emerged. Bistrategic popular adolescents had the highest popularity and above average aggression and prosocial behavior; they were viewed by peers as disruptive and angry but were otherwise well-adjusted.

Why We Should Still Treat by Neurosurgery Patients With Cushing Disease and a Normal or Inconclusive Pituitary MRI.

CONTEXT: In patients with Cushing disease (CD) and a typical image of adenoma at MRI, transsphenoidal surgery is consensual. However, when MRI is inconclusive or normal, some authors now advocate medical treatment instead. The implicit assumption is that modern MRI should miss only very small microadenomas that are too difficult to visualize at surgery. OBJECTIVE: To analyze the evolution with time of the performances of MRI and the outcomes of surgery in patients with CD with a typical image of adenoma vs an inconclusive or normal MRI. DESIGN AND PATIENTS: Retrospective single center study of 195 patients with CD treated by transsphenoidal surgery between 1992 and 2018, using first a translabial microscopic and then a transnasal endoscopic approach. Patients with inconclusive or normal MRI were explored by bilateral inferior petrosal sinus sampling. Four MRI groups were defined: microadenomas (n = 89), macroadenomas (n = 18), or MRI either inconclusive (n = 44) or normal (n = 44). RESULTS: The proportion of inconclusive/normal MRI decreased with time, from 60% (21/35) in 1992 to 1996 to 27% (14/51) in 2012 to 2018 (P = 0.037). In the four MRI groups, the per-operatory adenoma visualization rate was only slightly lower when MRI was normal (95%, 100%, 86%, 79%; P = 0.012) and postoperative remission rates were not different (85%, 94%, 73%, 75%; P = 0.11). CONCLUSION: The diagnostic performances of MRI have improved but remain inferior to the eye of an expert neurosurgeon, best assisted by endoscopy. We propose that patients with CD and an inconclusive/normal MRI be addressed by an expert neurosurgeon for transsphenoidal surgery rather than being treated medically.

A monozygotic twin difference study of friends' aggression and children's adjustment problems.

This study used the monozygotic (MZ) twin difference method to examine whether differences in friends' aggression increased the differences in MZ twins' aggression and depressive symptoms from kindergarten to Grade 1 and whether perceived victimization by the friend played a mediating role in this context. Participants were 223 MZ twin pairs. Results showed that differences in kindergarten friends' aggression significantly predicted an increased difference in MZ twins' aggression from kindergarten (mean age = 6.7 years) to Grade 1 (mean age = 7.5 years) for both boys and girls. Differences in perceived victimization by the friend mediated this association, albeit only in boys. Differences in perceived victimization by the friend also predicted an increase in MZ twins' differences in depressive symptoms. These results support the importance of friendship experiences during early childhood.
