Emotion dysregulation and functional connectivity in children with and without a history of major depressive disorder

Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) early in development may relate to later depression. Corticolimbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting-state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS; measuring ER), Child Depression Inventory (CDI-C; measuring depressive symptoms), and two resting-state MRI scans. Rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral prefrontal cortex [dlPFC] and amygdala) and six target ROIs thought to contribute to ER were examined. Findings showed that ER in school age did not predict depressive symptoms in adolescence, but did predict preadolescent increases in dlPFC-insula and dlPFC-ventromedial PFC rs-FC across diagnosis, as well as increased dlPFC-dorsal anterior cingulate cortex (dACC) rs-FC in children with a history of depression. Of these profiles, only dlPFC-dACC rs-FC in preadolescence predicted depressive symptoms in adolescence. However, dlPFC-dACC connectivity did not mediate the relationship between ER in school age and depressive symptoms in adolescence. Despite the absence of a direct relationship between ER and depressive symptoms and no significant rs-FC mediation, the rs-FC profiles predicted by ER are consistent with the hypothesis that emotion dysregulation is associated with abnormalities in top-down control functions. The extent to which these relationships might confer greater risk for later depression, however, remains unclear.     

Political Contacts: Analyzing the Role of Similarity in Theories of Prejudice

Over the last 50 years, many theories of prejudice reduction in social psychology have embraced the premise that intergroup contact allows people to recognize similarities between themselves, and that this perceived similarity overwhelms the social distance associated with intergroup antipathy. Given the mixed empirical evidence, however, we suggest that the positive effects of perceived similarity have been overemphasized. Although similarity may be sufficient for improved intergroup relations, the relationship between similarity and intergroup relations is far more complex than the literature usually suggests. Moreover, studying difference in intergroup contexts may yield new ways to resolve intergroup conflict and address group inequalities.     

The Role of Positive Psychology Constructs in Predicting Mental Health and Academic Achievement in Children and Adolescents: A Two-Year Longitudinal Study

This longitudinal study presents the first examination of the relation between positive psychology constructs, mental health and academic achievement of students in Portugal. Using a sample of 367 middle-school students, the study revealed that crosssectional and longitudinal patterns of correlations between positive variables were consistent with expectations for the most part and suggested that hope, life satisfaction and self-worth have meaningful relations with mental health and academic achievement. In addition, no significant changes were found between the variables in study across the administrations and throughout the two cohorts, and all the variables in study demonstrate moderate to high stability across a 1- and 2-year time frame. Hope predicts students?? academic achievement, and life satisfaction was the strongest predictor of mental health, over 2-years. The implications of the findings are discussed with reference to prior studies and for future research.     

Revised Reinforcement Sensitivity Theory and Laboratory Assessment of BIS and BAS in Children

There is considerable interest in Gray’s reinforcement sensitivity theory. However, few measures of the behavioral approach (BAS) and inhibition systems (BIS) exist for children. Moreover, the theory was substantially revised a decade ago and measurement instruments are still largely based on the old theory. Our aim was to revise questionnaire and laboratory assessments of BIS and BAS for children. Performance on the Point Scoring Reaction Time Task for Children-Revised (PSRTT-CR) conformed to theoretical expectations. Caregiver reports of BIS and BAS were associated with corresponding PSRTT-CR indices, suggesting cross-method convergent and discriminant validity. There was convergence with physiological correlates of BAS, but not physiological correlates of BIS. Overall, our revised measures represent promising instruments of children’s BIS and BAS.     

The Spanish version of the Wisconsin Personality Disorders Inventory-IV (WISPI-IV): tests of validity and reliability

Personality disorders (PD) are a prevalent class of mental disorders that interfere with functioning and cause subjective distress while increasing the intensity and duration of Axis I clinical syndromes, and therefore assessing PD is important even when PDs are not the focus of treatment. The purpose of these studies was to develop and test a new Spanish version of a self-report measure of PD, the Wisconsin Personality Inventory-IV (WISPI-IV) that would be psychometrically equivalent to the English version while also maintaining the same interpersonal content, which is based on Benjamin's analysis of the PD criteria using her Structural Analysis of Social Behavior (SASB) model (1974). Study 1 participants completed the WISPI-IV twice over a two-week interval. For Study 2, participants from two sites in Spain and one site in Argentina completed Spanish versions of the WISPI-IV and other personality measures. SASB-analysis of the translated items showed high correspondence between the interpersonal content of the English version and the Spanish version demonstrating theoretical validation in relation to other PD measures. The Spanish WISPI-IV showed satisfactory reliability based on test-retest correlations and alphas for internal consistency. Study 2 showed the Spanish WISPI-IV had good convergent validity with the Spanish versions of the IIP and SCID-II and performed similarly to the English versions of these measures. Our goal in translating the WISPI-IV was to extend this measure to Spanish-speakers in language that would be understood by different Hispanic sub-groups, however research team members and subjects had a variety of suggestions for changes in item wording. This reflects the difficulty with creating a "neutral" Spanish version of any assessment given regional differences.     

Self-deception's adaptive value: effects of positive thinking and the winner effect

There is a puzzle about why self-deception, a process that obscures the truth, is so pervasive in human behavior given that tracking the truth seems important for our survival and reproduction. William von Hippel and Robert Trivers argue that, despite appearances, there is good reason to think that self-deception is an adaptation by arguing: (1) self-deception leads to a positive self-perception and (2) a positive self-perception increases an individual's fitness. D.S. Neil Van Leeuwen, however, gives persuasive arguments against both steps. In response, we will defend both propositions, thereby supporting the conclusion that self-deception indeed has adaptive value. The first premise will be bolstered by a survey of the philosophical literature and empirical work on self-deception, whereas the second will be strengthened by empirical research on a behavioral phenomenon known as the winner effect.     

Ethnicity differences in child and parental outcomes following involvement the PACE program

This study investigated ethnic differences in the extent to which engagement (i.e., attendance and quality of participation) in the PACE (Parenting our Children to Excellence) program predicted positive child and parent outcomes. PACE is an 8-week preventive intervention aimed at parents of preschool children. The study investigated the relation of engagement to outcomes in an ethnically diverse sample of 298 African American and 280 European American parents. Overall results demonstrated that engagement in PACE significantly improved child and parent outcomes for both African American and European American participants. Some improvements were evident at post-assessment already and were maintained or became stronger at a one-year follow-up assessment, whereas others only became evident at follow-up. Specifically, results revealed that attendance in PACE significantly improved child coping competence and parenting stress for both the African American and European American samples. PACE attendance also significantly improved child behavior problems, parental satisfaction and parental efficacy for the European American sample. Findings indicate that PACE is a promising intervention for parents of African American and Caucasian preschoolers; although further research and program refinement is necessary in order to understand the mechanisms with the PACE intervention that seem to vary for African American compared to Caucasian families.     

Effects of sleep deprivation on cognitive performance by United States Air Force pilots

This study examined the effects of 35 h of continuous sleep deprivation on performance in a variety of cognitive tasks as well as simulated flight. Ten United States Air Force pilots completed the Multi-Attribute Task Battery (MATB), Psychomotor Vigilance Task (PVT), and Operation Span Task (OSPAN), as well as simulated flight at 3 h intervals over a 35 h sleep deprivation period. Performance declined on all tests after about 18–20 h of continuous sleep deprivation, although the degree to which performance degraded varied. During the second half of the sleep deprivation period, performance on the simulated flight was predicted by PVT and OSPAN reasonably well but much less so by the MATB. Variance from optimal flight performance was predicted by both PVT and OSPAN but each measure added incremental validity to the prediction. The two measures together accounted for 58% of the variance in flight performance in the second half of the sleep deprivation period.     

Parenting stress and depressive symptoms in postpartum mothers: Bidirectional or unidirectional effects?

Despite the consistent link between parenting stress and postpartum depressive symptoms, few studies have explored the relationships longitudinally. The purpose of this study was to test bidirectional and unidirectional models of depressive symptoms and parenting stress. Uniquely, three specific domains of parenting stress were examined: parental distress, difficult child stress, and parent–child dysfunctional interaction (PCDI). One hundred and five women completed the Beck Depression Inventory and the Parenting Stress Index – Short Form at 3, 7, and 14 months after giving birth. Structural equation modeling revealed that total parenting stress predicted later depressive symptoms, however, there were different patterns between postpartum depressive symptoms and different types of parenting stress. A unidirectional model of parental distress predicting depressive symptoms best fit the data, with significant stability paths but non-significant cross-lagged paths. A unidirectional model of depressive symptoms predicted significant later difficult child stress. No model fit well with PCDI. Future research should continue to explore the specific nature of the associations of postpartum depression and different types of parenting stress on infant development and the infant–mother relationship.     

Children's action-control behaviors (coping): A longitudinal validation of the behavioral inventory of strategic control

Abstract

Integrating multi-axial models with an action-theory perspective, we propose that children's coping strategies vary along four dimensions of strategic behavioral control: Direct Action, Indirect Action, Prosocial Action, and Antisocial Action. The Behavioral Inventory of Strategic Control (BISC) assesses these four general dimensions of strategic control. We contrast these four axial dimensions with six specific strategic combinations: Avoidance (Indirect-Antisocial), Emotional Support Seeking (Indirect-Prosocial), Social Exploitation (Indirect-Antisocial), Social Cooperation (Direct-Prosocial), Aggressive Individualism (Direct-Antisocial) and Hostility (Indirect-Antisocial). In a short-term longitudinal study (three occasions over four months) of 318 children (grades 2–6), we examined the validity of the BISC, showing that the hypothesized dimensional structure of children's strategic control behavior was strongly supported.
