Dysregulation profile in children of ethnoracially diverse at-risk families: Factor structure and longitudinal correlates.

The present work sought to confirm the factor structure and examine longitudinal strengths-based and mental health correlates of the dysregulation profile (DP) in children of at-risk fragile families of diverse ethnoracial backgrounds. The data came from the Fragile Families and Child Wellbeing Study (N = 2125 families). Mothers (Mage = 25.3) were mostly unmarried (74.6%), and children (51.4% boys) were identified as Black (47.0%), Hispanic (21.4%), White (16.7%), or multiracial or other backgrounds. Childhood DP was constructed using mother reports of the Child Behavior Checklist at age 9. Mothers' in-home parent-child interactions and depressive symptoms were assessed at child age 5. At age 15, children responded about their own mental health, social skills, and other strengths-focused outcomes. A bifactor DP structure fit well to the data, with the DP factor representing difficulties in self-regulation. Using SEM, we found that mothers who were more depressed and used less warm parenting at child age 5 had children who presented with higher DP at age 9. DP was in turn associated with less social skills, perseverance, optimism, and more anxiety, depression, and impulsivity at adolescence. Childhood DP appears to be relevant and applicable for at-risk, diverse families, and may also impede on children's future positive functioning.

Using latent profile analysis to uncover the combined role of anxiety sensitivity and test anxiety in students' state anxiety.

Background: Studies report a growing tendency for students to experience state anxiety in schools. However, the combination of individual susceptibilities likely to trigger students' anxious states remains unclear. Aims: This study examined whether distinct profiles of students emerge regarding their susceptibility to anxiety sensitivity and/or test anxiety and evaluated whether students' profile predicted anxious states. We also verified whether susceptibility profiles varied across gender, school level, and school type. Sample and methods: In total, 1,404 Canadian students in Grades 5 and 10 (589 boys; M age = 15.2, SD = 2.1) from 13 public and private schools completed self-reported measures of state/trait anxiety, anxiety sensitivity, and test anxiety. Results: Latent profile analyses identified four susceptibility profiles: (1) Double-susceptibility: highest anxiety sensitivity and test anxiety scores; (2) Unique-susceptibility to test anxiety: high test anxiety score and low anxiety sensitivity score; (3) Unique-susceptibility to anxiety sensitivity: high anxiety sensitivity score and low test anxiety score; and (4) No-susceptibility: lowest anxiety sensitivity and test anxiety scores. The profiles comprised 12, 9, 6, and 73% of the sample, respectively, and their membership varied across gender and school type, but not across school levels. A linear mixed-effect model showed that state anxiety varied significantly between profiles, where the Double-susceptibility profile predicted the highest state anxiety scores, followed by the two Unique-susceptibility profiles (indifferently), and the No-susceptibility profile. Conclusion: Beyond their theoretical contribution to the state-trait anxiety literature, these findings suggest that selective interventions designed more specifically for students with the Double-susceptibility profile may be worthwhile. Results also highlight the high proportion of students with the No-susceptibility profile and shed light on the reassuring portrait regarding students' anxiety.

Anxiety in the Classroom: Only Girls' Anxiety Is Related to Same-Sex Peers' Anxiety.

Many teens report experiencing anxiety in school, which can negatively impact their well-being. Considering that adolescents tend to adopt the same behaviors as their classmates with whom they spend, on average, 923 h every year, the current exploratory study (1) assessed whether an association exists between a student's state anxiety score and his/her classmates' average trait anxiety scores and (2) examined whether this association differed between boys and girls, as well as between elementary school and high school students. During two consecutive school years, 1044 Canadian students (59% girls) from six elementary schools (aged 10−12) and seven high schools (aged 15−17) completed the State-Trait Anxiety Inventory for Children. Multilevel analyses revealed a same-sex peer effect of classmates' anxiety in girls only (ß = 0.40, p < 0.001). This effect was similar for elementary and high school girls (ß = 0.07, p = 0.27). Interestingly, no association was found for boys, same-sex peers (ß = 0.11, p = 0.25), or opposite-sex peers (ß = −0.01, p = 1.00). Our results suggest that factors related to sex may reinforce anxiety in school settings. Future studies should confirm these results and explore the mechanisms involved in this sex-specific difference.

Staying informed without a cost: No effect of positive news media on stress reactivity, memory and affect in young adults.

INTRODUCTION: We read, see and hear news from various media sources every day. A large majority of the news is negative. A previous study from our laboratory showed that reading negative news is associated with both increased stress reactivity (measured via the stress hormone cortisol) and recall of the negative news segments in women. OBJECTIVES: The present study investigated the effects of positive news on cortisol stress reactivity, memory and affect using a methodology highly similar to the study on negative news that was previously used by our team. METHODS: Sixty-two healthy participants aged between 18 and 35 years (81% women) were randomly exposed to either positive or neutral news segments, followed by a laboratory stressor. We assessed participants' affect three times during the procedure and measured cortisol in saliva eight times (at 10-minute intervals). Twenty-four hours later, participants were contacted by phone to assess their recall of the news segments. RESULTS: Results showed that exposure to positive news, relative to neutral news, did not modulate participants' cortisol levels in response to the laboratory stressor. Positive news had no impact on memory recall of the news and did not change participants' positive or negative affect. Bayes factors suggested that these nonsignificant results are not attributable to low statistical power. CONCLUSION: Contrary to negative news, positive and neutral news do not modulate stress reactivity, memory and affect. These results suggest that people can stay informed without physiological and psychological costs when the news to which they are exposed adopt a positive or neutral approach.

Adult Women First Exposed to Early Adversity After 8 Years Old Show Attentional Bias to Threat.

Exposure to early adversity (EA) is associated with long-lasting dysregulations in cognitive processes sustained by brain regions that are sensitive to stress hormones: the hippocampus, the amygdala, and the prefrontal cortex. The Life Cycle Model of Stress highlights the importance of considering the timing at which EA began, as these brain regions follow distinct developmental trajectories. We aimed to test this hypothesis by assessing whether adults exposed to EA exhibit different cognitive patterns as a function of the age at which they were first exposed to EA. Eighty-five healthy men and women aged 21-40 years old (y/o) exposed to EA, as assessed by the Adverse Childhood Experience Questionnaire, were grouped based on the age of first exposure to EA: 0-2 y/o ("Infancy": hippocampal development), 3-7 y/o ("Early childhood": amygdala development) and after the age of 8 ("Childhood/Adolescence": frontoamygdala connectivity development). Declarative memory, attentional bias to threat and emotion regulation were measured. Results revealed increased attentional bias to threat in women first exposed to EA after 8 years. This result is in line with the Life Cycle Model of Stress and highlights the importance of considering the age at exposure to EA when investigating the effects of EA on cognitive processes.

Early childhood adversity and HPA axis activity in adulthood:The importance of considering minimal age at exposure.

Early adversity (EA) modulates stress hormone secretion in mixed directions. The Accumulation Model suggests that the number of EA predicts patterns of cortisol dysregulations, while the Life Cycle Model of Stress highlights the importance of considering the timing at which EA began, given that brain regions sensitive to stress hormones follow distinct developmental trajectories. We aimed to test these two models in 85 healthy men and women, aged 21-40 years old who reported having been exposed to EA during childhood. Participants were grouped based on the number of EA events to which they were exposed during their lifespan (Accumulation Model) and the age of first exposure to EA (Life Cycle Model). Diurnal and stress-induced reactive cortisol secretion were measured in all participants. Results showed that although the number of EA was not associated with patterns of basal or reactive cortisol secretion, adults first exposed to EA between the ages of 3 and 7 - an important time window for amygdala development - showed greater cortisol awakening response and lower cortisol reactivity relative to those first exposed to EA before 3 or after 7. These results provide support for the Life Cycle Model of Stress and highlight the importance of considering minimal age at exposure to EA when assessing the effects of early adversity on patterns of cortisol secretion.
