Stress,coping, executive function,and brain activation in adolescent offspring of depressed and nondepressed mothers

This study examined the associations among chronic stress, activation in the prefrontal cortex (PFC), executive function, and coping with stress in at-risk and a comparison sample of adolescents. Adolescents (N = 16; age 12–15) of mothers with (n = 8) and without (n = 8) a history of depression completed questionnaires, neurocognitive testing, and functional neuroimaging in response to a working memory task (N-back). Children of depressed mothers demonstrated less activation in the anterior PFC (APFC) and both greater and less activation than controls in distinct areas within the dorsal anterior cingulate cortex (dACC) in response to the N-back task. Across both groups, activation of the dorsolateral PFC (DLPFC; Brodmann area [BA9]) and APFC (BA10) was positively correlated with greater exposure to stress and negatively correlated with secondary control coping. Similarly, activation of the dACC (BA32) was negatively correlated with secondary control coping. Regression analyses revealed that DLPFC, dACC, and APFC activation were significant predictors of adolescents’ reports of their use of secondary control coping and accounted for the effects of stress exposure on adolescents’ coping. This study provides evidence that chronic stress may impact coping through its effects on the brain regions responsible for executive functions foundational to adaptive coping skills.     

Preliminary Evidence for the Effectiveness of Dialectical Behavior Therapy for Adolescents

This meta‐analysis evaluated the effectiveness of dialectical behavior therapy for adolescents in reducing symptoms of depression, anxiety, self‐injury, and suicide risk. Twelve between‐group studies (N = 834) were chosen that met the inclusion criteria. Results revealed small‐to‐medium Hedges's g effect sizes for all 4 symptoms compared with control and alternative treatment groups. However, the small number of effect sizes available for each analysis limited the generalizability of the findings. Implications and suggestions for future research are discussed.     

Verbal Working Memory as a Longitudinal Mechanism of Vocabulary Problems in Preschoolers with ADHD

Elucidation of early potential risk factors of Attention-Deficit/Hyperactivity Disorder (ADHD) is important to allow for early identification of ADHD and targeted early intervention for children with ADHD. Delayed language skills, particularly poor vocabulary, is an early-developing potential risk factor that is thought to be involved in developmental pathways to ADHD; however, mechanisms explaining the relationship between poor vocabulary skills and ADHD symptoms are unclear and warrant investigation. The present study examines the relationship between poor vocabulary skills and ADHD symptoms by testing cognitive mechanisms, namely verbal working memory (WM), that might account for this link. Participants were 109 young children between the ages of three and six and their primary caregivers. Diagnostic information on ADHD symptoms was available from parents and teachers/daycare providers via standardized rating forms. Vocabulary skills and WM were measured through child performance on laboratory tasks. Mediation analyses found poor verbal working memory significantly partially explained the vocabulary-ADHD association for both parent and teacher-rated ADHD symptoms. Further, effects of verbal WM on the association between poor vocabulary and increased ADHD symptoms largely held at one-year follow-up. Development of early interventions targeting verbal WM may be a promising new direction for early ADHD intervention work.

National Valuing of Character Strengths and Indicators of National Development: A Pilot Study

Character strengths are personal qualities that have communal value and have been linked to personal happiness and well-being. Little research has investigated the degree to which strengths are valued across nations. Similarly, while certain strengths have been associated with indicators of well-being on an individual level, it is yet to be explored which strengths are associated with indicators of national development and well-being. The present study examined the relationship between perceived national valuing of character strengths and key national indicators. A sample of 2119 adults from 84 countries were asked to rate the extent to which each of 24 character strengths is valued by their country. Strength ratings were then compared to indices of national functioning: happiness, freedom, corruption, and gross domestic product per capita measured at purchasing power parity (GDP). The strengths the participants perceived as valued by their countries differed from their self-evaluations of their character strengths. Bravery was the most valued strength across all geographic regions and countries, and humility was the least. Valuing of humor was most consistently and strongly related to happiness. GDP was associated with less prudence, kindness, fairness, and honesty, and more bravery, perseverance, and spirituality. Greater honesty was reflective of less corruption. Freedom was inconsistently related to valuations of strengths. This study should be considered a pilot given its limitations, but it suggests the degree to which a society values certain socially important person variables does not appear to affect individual expression of character strengths, but may be related to national functioning.

     

A review of existing measures of attentional biases in body image and eating disorders research

Cognitive theories emphasise the important role of attentional biases in the development and maintenance of body image issues and eating pathology. A wealth of research has been conducted to examine attentional biases toward body‐related information among individuals with eating pathology. However, there is considerable variability in the methods that have been used to measure attention and, importantly, these methods tap into different attentional processes. Given the multifaceted nature of attention, it is important for researchers to select the right tools to test their hypotheses. This review critically evaluates the attentional measures that have been used in previous research, primarily the modified Stroop task, dot probe task, visual search task, and eyetracking. The strengths and limitations of each measure will be discussed in order to provide a guide for researchers to further investigate the attentional mechanisms underlying body image issues and eating disorders. Overall, we recommend that researchers use a combination of eyetracking technology and specific reaction‐time measures that target the specific attentional mechanism of interest.     

Does preference rank predict substitution for the reinforcer for problem behavior? a behavioral economic analysis

Predictions made under low response requirements inherent in most preference assessments (PAs) do not guarantee the utility of stimuli in treatments. We examined whether PA rank would predict how well stimuli supported compliance for children with escape‐maintained problem behavior by examining the relation between PA rank and demand elasticity across five fixed‐ratio values. Three patterns were observed: All stimuli were selected equally across values, higher ranked stimuli were selected more at higher values, and something other than the highest ranked stimulus was selected more at higher values (i.e., mixed correspondence).
