Overgeneral autobiographical memory predicts diagnostic status in depression

Major depressive disorder (MDD) is characterised by difficulties in retrieving specific autobiographical memories, with a significant propensity towards categoric memories (i.e. memories of a summary type). Previous studies have demonstrated that this overgeneral memory is a valid predictor of the course of depression, with reduced specificity being associated with worse outcome. Most of these studies have employed continuous measures of depression to assess the course of the symptoms. This study investigated whether overgeneral memory also predicts clinical status at follow-up (i.e. whether patients still meet criteria for depression). Patients who fulfilled criteria for major depressive disorder were tested shortly after admission to the hospital and were retested some weeks later. It was found that lower levels of specificity or a higher number of categoric memories were associated with a higher probability of still being diagnosed with MDD. These memory variables outperformed other relevant indices, such as depression severity, rumination, level of self-esteem and dysfunctional attitudes.     

Sudden gains in group cognitive-behavioral therapy for panic disorder

The current study investigates sudden gains (rapid symptom reduction) in group cognitive-behavioral therapy for panic disorder. Sudden gains occurring after session 2 of treatment predicted overall symptom reduction at treatment termination and some changes in cognitive biases. Meanwhile, sudden gains occurring immediately following session 1 were not associated with symptom reduction or cognitive change. Together, this research points to the importance of examining sudden gains across the entire span of treatment, as well as the potential role of sudden gains in recovery from panic disorder.     

Gay,Lesbian, and Queer Theologies: Origins,Contributions, and Challenges

Abstract : Theologians and biblical scholars have been writing about Christianity and homosexuality for over three decades, but lesbian/gay and queer theologies are still unfamiliar. Since questions about lesbian, gay, and queer Christians are confronting many denominations, it is important to study these proposals. This essay argues that lesbian/gay theologies trace their histories to theologies of liberation, while queer theology is indebted to postmodern and queer theories. Recent Christological and anthropological proposals are presented, and the essay concludes by exploring the distinct political implications of these theological proposals.     

Are autistic traits autistic?

According to the extreme male brain theory of autism ( Baron‐Cohen, 2002 ), autistic traits would be extreme manifestations of typical male behaviours. The Auyeung et al. (2009) paper establishes a link between autistic traits and higher fetal testosterone (fT) levels in typically developing children. We argue that the construct behind this relationship needs further investigation. First, the link between fT levels and sexually dimorphic traits, that are for example, associated with empathizing and systemizing, is controversial. Likewise, describing autistic behaviours as being extreme male‐like is debatable. The cerebral hemisphere laterality pattern of individuals with autism also seems to differ from the pattern typically observed in males. Moreover, the parallel that should exist, according to the fT theory, between individuals with autism and individuals with congenital adrenal hyperplasia (CAH), because of their high fT levels, is unclear. The theory implying fT levels in autism fails to account for a big part of autism, and the link between fT and normal ‘autistic traits’ hardly demonstrates the causal link between fT and autism.     

Stress assignment in aphasia: word and non-word reading and non-word repetition

This paper investigates stress assignment in Dutch aphasic patients in non-word repetition, as well as in real-word and non-word reading. Performance on the non-word reading task was similar for the aphasic patients and the control group, as mainly regular stress was assigned to the targets. However, there were group differences on the real-word reading and non-word repetition tasks. Unlike the non-brain-damaged group, the patients showed a strong regularization tendency in their repetition of irregular patterns. The patients' stress error patterns suggest an impairment in retention or retrieval of targets with irregular stress patterns. Limited verbal short-term memory is proposed as a possible underlying cause for the stress difficulties.     

Meta‐CART: A tool to identify interactions between moderators in meta‐analysis

In the framework of meta‐analysis, moderator analysis is usually performed only univariately. When several study characteristics are available that may account for treatment effect, standard meta‐regression has difficulties in identifying interactions between them. To overcome this problem, meta‐CART has been proposed: an approach that applies classification and regression trees (CART) to identify interactions, and then subgroup meta‐analysis to test the significance of moderator effects. The previous version of meta‐CART has its shortcomings: when applying CART, the sample sizes of studies are not taken into account, and the effect sizes are dichotomized around the median value. Therefore, this article proposes new meta‐CART extensions, weighting study effect sizes by their accuracy, and using a regression tree to avoid dichotomization. In addition, new pruning rules are proposed. The performance of all versions of meta‐CART was evaluated via a Monte Carlo simulation study. The simulation results revealed that meta‐regression trees with random‐effects weights and a 0.5‐standard‐error pruning rule perform best. The required sample size for meta‐CART to achieve satisfactory performance depends on the number of study characteristics, the magnitude of the interactions, and the residual heterogeneity.     

Exploring the Impact of Engaged Teachers on Implementation Fidelity and Reading Skill Gains in a Blended Learning Reading Program

The number of K–12 classrooms adopting blended learning models is rapidly increasing and represents a cultural shift in teaching and learning; however, fidelity of implementation of these new blended learning programs varies widely. This study aimed to examine the role of teacher engagement in student motivation and achievement in a blended learning environment. Reading skill data were analyzed from 19,366 students across 624 schools led by teachers defined as engaged users of a blended learning reading program (Lexia Reading Core5 [Core5]). Results showed significant improvements in reading skills during the analyzed period for the students of the engaged teachers in comparison to neighboring classrooms (171,850 students in the same 624 schools) of less engaged teachers.     

Cigarette smoking and depressive symptoms: a longitudinal study of adolescents and young adults

Cigarette smoking and depressive symptoms have been shown to be related in previous research. This paper examined the relationship between cigarette smoking and depressive symptoms in a longitudinal sample of 688 adolescents and young adults through surveys conducted over 13 yr. The results indicate that a history of earlier cigarette smoking in adolescence predicts later depressive symptoms in the late twenties. The study also suggests that depressive symptoms during adolescence predict cigarette smoking in the late twenties but not above and beyond prior smoking. These results help clarify and expand current knowledge on the links between cigarette smoking and depression. The results point to several clinical implications for treatment of both cigarette smoking and depressive symptoms among both adolescents and young adults.     

The regression trunk approach to discover treatment covariate interaction

The regression trunk approach (RTA) is an integration of regression trees and multiple linear regression analysis. In this paper RTA is used to discover treatment covariate interactions, in the regression of one continuous variable on a treatment variable withmultiple covariates. The performance of RTA is compared to the classical method of forward stepwise regression. The results of two simulation studies, in which the true interactions are modeled as threshold interactions, show that RTA detects the interactions in a higher number of cases (82.3% in the first simulation study, and 52.3% in the second) than stepwise regression (56.5% and 20.5%). In a real data example the final RTA model has a higher cross-validated variance-accounted-for (29.8%) than the stepwise regression model (12.5%). All of these results indicate that RTA is a promising alternative method for demonstrating differential effectiveness of treatments.

Reliability and validity of the Revised Children's Manifest Anxiety Scale in a French-Canadian sample

The aim of this study was to examine the reliability and validity of a French version of the Revised Children's Manifest Anxiety Scale (RCMAS). A sample of 2,666 school-age French-Canadian children completed the questionnaire. With regard to factor structure, the 5-factor model found in U.S. normative samples was confirmed. The internal consistency of the 5 scales and of the 2 global scales was good to excellent. Test-retest reliabilities after a 6-month period were also similar to those of the original version. Finally, the concurrent validity, assessed by a correlation with the State-Trait Anxiety Inventory for Children, was also found to be good. Results of the present study show that the French version of the RCMAS is a good instrument to assess anxiety in children.
