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.     

Career Preparation: A Longitudinal, Process-Oriented Examination

Preparing for an adult career through careful planning, choosing a career, and gaining confidence to achieve career goals is a primary task during adolescence and early adulthood. The current study bridged identity process literature and career construction theory (Savickas, 2005) by examining the commitment component of career adaptability, career preparation (i.e., career planning, career decision-making, and career confidence), from an identity process perspective (Luyckx, Goossens, & Soenens, 2006). Research has suggested that career preparation dimensions are interrelated during adolescence and early adulthood; however, what remains to be known is how each dimension changes over time and the interrelationships among the dimensions during the transition from high school. Drawing parallels between career preparation and identity development dimensions, the current study addressed these questions by examining the patterns of change in each career preparation dimension and parallel process models that tested associations among the slopes and intercepts of the career preparation dimensions. Results showed that the career preparation dimensions were not developing similarly over time, although each dimension was associated cross-sectionally and longitudinally with the other dimensions. Results also suggested that career planning and decision-making preceded career confidence. The results of the current study supported career construction theory and showed similarities between the processes of career preparation and identity development.     

Best Unifiers in Transitive Modal Logics

This paper offers a brief analysis of the unification problem in modal transitive logics related to the logic S4: S4 itself, K4, Grz and Gödel-Löb provability logic GL. As a result, new, but not the first, algorithms for the construction of ??best?? unifiers in these logics are being proposed. The proposed algorithms are based on our earlier approach to solve in an algorithmic way the admissibility problem of inference rules for S4 and Grz. The first algorithms for the construction of ??best?? unifiers in the above mentioned logics have been given by S. Ghilardi in [16]. Both the algorithms in [16] and ours are not much computationally efficient. They have, however, an obvious significant theoretical value a portion of which seems to be the fact that they stem from two different methodological approaches.     

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.     

Changes in EEG cross-frequency coupling during cognitive behavioral therapy for social anxiety disorder

Coupling between EEG delta and beta oscillations is enhanced among anxious and healthy individuals during anticipatory anxiety. EEG coupling patterns associated with psychotherapy have not yet been quantified in socially anxious individuals. In this study, we used a double baseline, repeated measures design, in which 25 adults with a principal diagnosis of social anxiety disorder completed 12 weekly sessions of standardized group cognitive behavioral therapy and four EEG assessments: two at pretreatment, one at midtreatment, and one at posttreatment. Treatment was associated with reductions in symptom severity across multiple measures and informants, as well as reductions in delta-beta coupling at rest and during speech anticipation. Moreover, the clinical group exhibited greater coupling at pretreatment than did post hoc control participants with low social anxiety. The EEG cross-frequency profiles in the clinical group normalized by the posttreatment assessment. These findings provide evidence of concomitant improvement in neural and behavioral functioning among socially anxious adults undergoing psychotherapy.     

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.     

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.     

A New Perspective on Temperamental Shyness: Differential Susceptibility to Endoenvironmental Influences

In this review, we adapt and extend a model recently used to account for differences in risk and resiliency outcomes to explain individual differences in temperamental shyness. The differential susceptibility to environmental influences model posits that heightened biological sensitivity and reactivity in the individual can predict different outcomes for better or for worse, depending on environmental influences outside (i.e., exogenous) of the individual. In this article, we extend this existing model and argue that the environment can also be conceptualized as a unique set of dynamic conditions and influences operating within (i.e., endogenous) the individual that are orthogonal to some biological sensitivity factors. In this new model, continuous brain electrical activity at rest constitutes one endogenous environmental condition that can vary (leftward to rightward) and influence gene expression to confer different outcomes, for better (sociability) or for worse (shyness). We then discuss how this model can be tested, as well as its potential implications for theory, development, and practice.
