A model‐based intervention for depressed mothers and their infants

Many studies have reported on the adverse effects of maternal depression on offspring. Infants of depressed mothers are found to be more likely at risk to develop mental and socioemotional problems. In this study, an early intervention program is presented that aims to improve the interaction between depressed mothers and their infants to prevent developmental problems in the children. The program has recently been introduced in the Dutch Community Mental Health Centers as part of a national multicomponent program to reduce the risk of psychiatric and social problems in the offspring of parents with a mental disorder. The intervention for depressed mothers with babies is based on a transactional model in which the mother–child interaction plays a key role in explaining the development of socioemotional problems in the children. The model as discussed in the first part of this article addresses a range of evidenced‐based parental, child, and contextual risk factors that effect the quality of the interactions between depressed mothers and their infants and that contribute to both vulnerability and resilience of the children during later childhood and adolescence. ©2005 Michigan Association for Infant Mental Health.     

What Does the DAP:IQ Measure?: Drawing Comparisons between Drawing Performance and Developmental Assessments

Human figure drawing tasks such as the Draw-a-Person test have long been used to assess intelligence (F. Goodenough, 1926). The authors investigate the skills tapped by drawing and the risk factors associated with poor drawing. Self-portraits of 345 preschool children were scored by raters trained in using the Draw-a-Person Intellectual Ability test (DAP:IQ) rubric (C. R. Reynolds & J. A. Hickman, 2004). Analyses of children's fine motor, gross motor, social, cognitive, and language skills revealed that only fine motor skill was an independent predictor of DAP:IQ scores. Being a boy and having a low birth weight were associated with lower DAP:IQ scores. These findings suggest that although the DAP:IQ may not be a valid measure of cognitive ability, it may be a useful screening tool for fine motor disturbances in at-risk children, such as boys who were born at low birth weights. Furthermore, researchers who use human figure drawing tasks to measure intelligence should measure fine motor skill in addition to intelligence.     

Using a Videogame Intervention to Reduce Anxiety and Externalizing Problems among Youths in Residential Care: an Initial Randomized Controlled Trial

Residential care is among the most intensive forms of treatment in youth care. It serves youths with severe behavioral problems and is primarily focused on targeting externalizing problems. Despite best efforts, effect sizes remain moderate, which may be due to the disregarding of internalizing symptoms – in particular anxiety - and to limitations regarding the delivery model of interventions. This initial randomized controlled trial (n?=?37) aimed to examine the effectiveness of a biofeedback videogame intervention (Dojo) as an addition to treatment as usual for youths with and without intellectual disability (ID) in residential care with clinical levels of anxiety and externalizing problems. Dojo targets both anxiety and externalizing problems, and incorporates the principles of conventional treatment, while addressing its limitations. Youths were randomly assigned to play Dojo (eight 30-min gameplay sessions) or to treatment as usual (TAU). Measurements of anxiety and externalizing problems were conducted at baseline, posttreatment, and 4-months follow-up through youths’ self-report and mentor-report. Completers-only analyses revealed decreases in self-reported anxiety and externalizing problems, and mentor-reported anxiety at posttreatment for participants in the Dojo condition compared to the control condition. Only mentor-reported anxiety was maintained at follow-up. No effect was found for mentor-reported externalizing problems. These findings provided preliminary evidence that Dojo is a promising, innovative intervention that engages high-risk youths. Practical implications are discussed.     

Stigma modifies the association between social support and mental health among sexual violence survivors in the Democratic Republic of Congo: implications for practice

Background and Objectives: The aim of this study was to further understanding of the relationship between social support, internalized and perceived stigma, and mental health among women who experienced sexual violence in the eastern Democratic Republic of Congo (DRC).

Methods: Drawing from baseline survey data collected in eastern DRC, researchers conducted a secondary cross-sectional analysis using data from 744 participants. Regression and moderation analyses were conducted to examine associations between social support variables, felt stigma, and depression, anxiety and posttraumatic stress disorder (PTSD).

Results: Emotional support seeking and felt stigma were positively associated with increased symptom severity across all three mental health variables. Stigma modified associations between emotional support seeking and depression (t?=??2.49, p?=?.013), anxiety (t?=??3.08, p?=?.002), and PTSD (t?=??2.94, p?=?.003). Increased frequency of emotional support seeking was associated with higher mental health symptoms of anxiety and PTSD among women experiencing all levels of stigma.

Conclusions: Enhancing understanding of social support and stigma may inform research and intervention among Congolese forced migrant populations across circumstances and geographic locations. Implications for practice and research are discussed.     

Dorsal stream function in the young child: an fMRI investigation of visually guided action

Visually guided action is a ubiquitous component of human behavior, but the neural substrates that support the development of this behavior are unknown. Here we take an initial step in documenting visual‐motor system development in the young (4‐ to 7‐year‐old) child. Through functional MRI and by using a new technique to measure the mechanisms underlying real‐time visually guided action in the MRI environment, we demonstrate that children rely primarily on the IPS and cerebellum for this complex behavior. This pattern is consistent across three different visually guided actions, suggesting generalizability of these neural substrates across such tasks. However, minor differences in neural processing across tasks were also demonstrated. Overall, results are interpreted as demonstrating that the functions of the dorsal stream can be viewed as fairly mature in the young child. These results provide a benchmark for future studies that aim to understand the development of the neural circuitry for visually guided action.     

Meta-analysis of the efficacy and acceptability of cognitive-behavioural therapy for Arab adult populations experiencing anxiety,depression or post-traumatic stress disorder

A meta-analysis of the literature of cognitive behaviour therapy (CBT) with Arab adult populations experiencing anxiety, depression or post-traumatic stress disorder (PTSD) was conducted. Nine studies (n = 536) met the eligibility criteria. Three of the nine studies (33%) were randomised control trials using waitlist control groups. All studies (100%) reported a statistically significant reduction in psychological symptoms at post-treatment with large effect sizes for anxiety (effect size, 95% confidence interval) (1.44 [1.29, 1.59]), depression (1.26 [1.16, 1.35]) and PTSD (2.08 [1.94, 2.23]). Six out of the nine studies (67%) collated follow-up data and reported that reductions of psychological symptoms were maintained at follow-up. An average dropout rate of 26% indicated good overall acceptability. Five out of nine (55%) of the trials reported diagnostic remission rates and of those trials the mean remission rate was 31%). Five of the nine eligible studies (55%) delivered remotely via Internet or telephone were found to have similar effect sizes as face-to-face CBT. The current meta-analysis indicates the potential of CBT, delivered either face-to-face or via internet, as efficacious and acceptable interventions for the treatment of anxiety, depression and PTSD for Arab adult populations.     

On the interplay of visuospatial and audiotemporal dominance: Evidence from a multimodal kappa effect

When participants judge multimodal audiovisual stimuli, the auditory information strongly dominates temporal judgments, whereas the visual information dominates spatial judgments. However, temporal judgments are not independent of spatial features. For example, in the kappa effect, the time interval between two marker stimuli appears longer when they originate from spatially distant sources rather than from the same source. We investigated the kappa effect for auditory markers presented with accompanying irrelevant visual stimuli. The spatial sources of the markers were varied such that they were either congruent or incongruent across modalities. In two experiments, we demonstrated that the spatial layout of the visual stimuli affected perceived auditory interval duration. This effect occurred although the visual stimuli were designated to be task-irrelevant for the duration reproduction task in Experiment 1, and even when the visual stimuli did not contain sufficient temporal information to perform a two-interval comparison task in Experiment 2. We conclude that the visual and auditory marker stimuli were integrated into a combined multisensory percept containing temporal as well as task-irrelevant spatial aspects of the stimulation. Through this multisensory integration process, visuospatial information affected even temporal judgments, which are typically dominated by the auditory modality.     

Unpacking Social Avoidance and Substance Use in Social Anxiety: Does Extraversion Explain Behavior Variability?

Social anxiety is characterized by heightened fear and anxiety associated with social situations, resulting in the use of avoidance behaviors. Contemporary models suggest that some individuals with social anxiety may choose to completely avoid social situations, while others may seek social connections and interactions and utilize avoidance behaviors such as substance use as a means of distress tolerance, while engaging in these situations. Our aim is to test a theoretical model whereby extraversion could help to explain the heterogenous nature of social anxiety in relation to these behaviors. Lower levels of extraversion have been commonly associated with withdrawal behaviors and higher levels of extraversion have been associated with behaviors commonly enacted in social situations. Understanding factors which predict the use of one behavior over another is imperative to the conceptualization and successful treatment of patients with social anxiety. A sample of 195 college students completed self-report measures and a 10-day experience sampling diary with five diary signals each day. Participants were asked to rate their current negative emotions and behaviors during each diary signal. Using a multilevel modeling approach, we tested the association between social anxiety symptoms and negative affect predicting engagement in substance use or social avoidance and tested whether extraversion moderated this association. Negative affect was included as a covariate given the established associations between elevations in negative affect predicting both behaviors. Results indicated that higher levels of social anxiety symptoms and negative affectivity increased the probability of social avoidance and substance use, and extraversion was a significant predictor for only substance use. Moderation analysis indicated that extraversion moderated the relationship between social anxiety and substance use, suggesting a stronger positive relationship between substance use and social anxiety for individuals higher in extraversion. However, extraversion was not a significant moderator between social anxiety and social avoidance. Overall, the findings suggest that extraversion could be a key factor predicting the use of substances amongst individuals with social anxiety and may need further consideration in treatment.

     

Late‐ but not early‐onset blindness impairs the development of audio‐haptic multisensory integration

Integrating different senses to reduce sensory uncertainty and increase perceptual precision can have an important compensatory function for individuals with visual impairment and blindness. However, how visual impairment and blindness impact the development of optimal multisensory integration in the remaining senses is currently unknown. Here we first examined how audio‐haptic integration develops and changes across the life span in 92 sighted (blindfolded) individuals between 7 and 70 years of age. We used a child‐friendly task in which participants had to discriminate different object sizes by touching them and/or listening to them. We assessed whether audio‐haptic performance resulted in a reduction of perceptual uncertainty compared to auditory‐only and haptic‐only performance as predicted by maximum‐likelihood estimation model. We then compared how this ability develops in 28 children and adults with different levels of visual experience, focussing on low‐vision individuals and blind individuals that lost their sight at different ages during development. Our results show that in sighted individuals, adult‐like audio‐haptic integration develops around 13–15 years of age, and remains stable until late adulthood. While early‐blind individuals, even at the youngest ages, integrate audio‐haptic information in an optimal fashion, late‐blind individuals do not. Optimal integration in low‐vision individuals follows a similar developmental trajectory as that of sighted individuals. These findings demonstrate that visual experience is not necessary for optimal audio‐haptic integration to emerge, but that consistency of sensory information across development is key for the functional outcome of optimal multisensory integration.     

Scientific Facts and Methods in Public Reason

Should scientific facts and methods have an epistemically privileged status in public reason? In Rawls’s public reason account he asserts what we will label the Scientific Standard Stricture: citizens engaged in public reason must be guided by non-controversial scientific methods, and public reason must be in line with non-controversial scientific conclusions. The Scientific Standard Stricture is meant to fulfill important tasks such as enabling the determinateness and publicity of the public reason framework. However, Rawls leaves us without elucidation with regard to when science is and is not ‘non-controversial’ and more importantly, we are left without a justification for a stricture which excludes certain controversial beliefs and methods of inquiry from the realm of political justification. In this article, we offer what we deem to be the most plausible interpretation of Rawls’s Scientific Standards Stricture. We then use Rawls’s general theoretical framework to examine various potential justifications for privileging these ‘non-controversial’ scientific methods and conclusions. We conclude that no viable justification is available to Rawls.
