Differences Between Synchronic and Idealized Diachronic Theory-Elements: A Reply to Martti Kuokkanen and Timo Tuomivaara

This paper deals with the connection between the Boyle-Mariotte-law and the Van der Waals-law from the perspective of the Structuralist Theory Conception as well as the Pragmatic Idealization Concept (PIC). It was inspired by an interesting paper by Martti Kuokkanen and Timo Tuomivaara, recently published in this journal.¹ One result of the Kuokkanen-Tuomivaara-paper is that the Boyle-Mariotte-law is not an idealized law and therefore not an idealized special case of the Van der Waals-law, but that its models can be expanded to the models of an idealized special case of the Van der Waals-law. From the perspective of idealized diachronic theory-elements and -nets the second part of this result shall be questioned.     

Empirically based dimensions of externalizing symptoms in children and adolescents: a multitrait-multisource approach

The present study sought to refine knowledge about the structure underlying externalizing dimensions. From a “top-down” ICD/DSM-based perspective, externalizing symptoms can be categorized into attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). From a “bottom-up” developmental theory-based perspective, disruptive behaviors can be meaningfully described as aggressive (AGG) and rule-breaking (RB) behaviors. We analyzed five large data sets comprising externalizing symptom ratings obtained with a screening instrument using different sources (parents, teachers, self-ratings) from different samples. Using confirmatory factor analyses, we evaluated several factor models (unidimensional; correlated factors; bifactor (S-1) models) derived from an ICD/DSM- and theory-based perspective. Our optimally fitting models were assessed for measurement invariance across all sources, sample settings, and sex. Following several model-based criteria (model fit indices; factor loadings; omega statistics; model parsimony), we discarded our models stepwise and concluded that both the ICD/DSM-based model with three correlated factors (ADHD, ODD, CD) and the developmental theory-based model with three correlated factors (ADHD, AGG, RB) displayed a statistically sound factor structure and allowed for straightforward interpretability. Furthermore, these two models demonstrated metric invariance across all five samples and across sample settings (community, clinical), as well as scalar invariance across sources and sex. While the dimensions AGG and RB may depict a more empirically coherent view than the categorical perspective of ODD and CD, at this point we cannot clearly determine whether one perspective really outperforms the other. Implications for model selection according to our model-based criteria and clinical research are discussed.

     

Cognitive Behavioral Therapy for Social Anxiety Disorder: Predictors of Treatment Outcome in a Quasi-Naturalistic Setting

We examined the outcomes of individual cognitive behavioral therapy (CBT) for social anxiety disorder (SAD) in a sample of 93 adults seeking treatment in a university outpatient clinic specializing in CBT for SAD. Treatment followed the structure of a manual, but number of sessions varied according to client needs. After approximately 20 weeks of therapy, patients’ social anxiety had decreased and their quality of life had increased. Patients with more severe SAD or comorbid major depressive disorder (MDD) at pretreatment demonstrated higher levels of social anxiety averaged across pre- and posttreatment. However, clinician-rated severity of SAD, comorbid MDD, or comorbid generalized anxiety disorder did not predict treatment outcome. Higher pretreatment scores on measures of safety behaviors and cognitive distortions were associated with higher social anxiety averaged across pre- and posttreatment and predicted greater decreases from pre- to posttreatment on multiple social anxiety outcome measures. We found no predictors of change in quality of life. Those with high levels of safety behaviors and distorted cognitions may benefit more from CBT, perhaps due to its emphasis on targeting avoidance through exposure and changing distorted thinking patterns through cognitive restructuring methods. Our study lends support to the body of research suggesting that manualized CBT interventions can be applied flexibly in clinical settings with promising outcomes for patients over a relatively short course of therapy.     

Differenzialdiagnose schizoaffektive Störung versus bipolare Störung

This case presentation describes a 22-year-old woman after an episode of psychotic mania. Manic-psychotic and depressive episodes, partially with psychotic symptoms, and different diagnoses have been documented for the past 5 years, raising the question of the differential diagnosis between bipolar disorder and schizoaffective disorder. Depending on the classification (ICD-10 versus DSM-5), schizoaffective disorder is defined differently. According to ICD-10, schizoaffective episodes can be diagnosed when affective and schizophrenic symptoms occur simultaneously. In a different approach, DSM-V requires psychotic symptoms in the absence of major mood episodes for at least 2 weeks in the course of the disorder.     

Postnatal Depression and Infant Health Practices Among High-Risk Women

Women’s postnatal depressive symptoms have been associated with many adverse outcomes for children. The current study examined the frequency association with relative risk between postnatal depressive symptoms and mothers’ use of preventative infant health practices. The study used the Edinburgh Postnatal Depression Scale (EPDS) and Parental Health and Depression Questionnaire (PHDQ) to identify women’s depressive symptoms in a prospective longitudinal sample of 134 high-risk non-white mothers receiving well-baby health services. Unadjusted frequency comparisons examined the effect of women’s postnatal depressive symptoms on infant outcomes. Results found that compared to 60 women without postnatal depressive symptoms, 74 women with symptoms engaged in significantly fewer well-child health-visits, were less likely to use home safety devices or place their infants in the preferred back-to-sleep position, and did not complete immunizations. Depressed women were also more likely to lack knowledge of nurturing and sensitive parenting, use corporal punishment and inappropriate foods, and to show poor parenting practices. These findings provide additional supportive evidence that more efforts are needed to identify and assess women’s depressive symptoms to promote health and safety of young children. Methodological limitations and recommendations for future research are addressed.     

Mix me a list: Context moderates the truth effect and the mere-exposure effect

When participants are repeatedly presented with an unfamiliar stimulus, this stimulus is rated as more likable (mere-exposure effect) or more valid (truth effect) as compared with a similar non-repeated stimulus. Both effects have been discussed as effects of fluency. Typical research designs on these effects involve a test phase in which ratings of both repeated and non-repeated stimuli are required. Based on research on moderators of fluency effects, we propose that the procedure of assessing the effects with mixed lists of repeated and non-repeated stimuli contributes strongly to the emergence of both effects. Two experiments found that the truth effect and the mere-exposure effect were strongly moderated by whether mixed lists or only repeated items were used at the test phase: whereas strong effects occurred in a context of repeated and non-repeated stimuli, the effects vanished with only repeated stimuli. Methodological and theoretical implications are discussed.
