Interpretation and Expectation in Childhood Anxiety Disorders: Age Effects and Social Specificity

Theory and treatment for childhood anxiety disorders typically implicates children’s negative cognitions, yet little is known about the characteristics of thinking styles of clinically anxious children. In particular, it is unclear whether differences in thinking styles between children with anxiety disorders and non-anxious children vary as a function of child age, whether particular cognitive distortions are associated with childhood anxiety disorders at different child ages, and whether cognitive content is disorder-specific. The current study addressed these questions among 120 7–12 year old children (53% female) who met diagnostic criteria for social anxiety disorder, other anxiety disorder, or who were not currently anxious. Contrary to expectations, threat interpretation was not inflated amongst anxious compared to non-anxious children at any age, although older (10–12 year old) anxious children did differ from non-anxious children on measures of perceived coping. The notion of cognitive-content specificity was not supported across the age-range. The findings challenge current treatment models of childhood anxiety, and suggest that a focus on changing anxious children’s cognitions is not warranted in mid-childhood, and in late childhood cognitive approaches may be better focussed on promoting children’s perceptions of control rather than challenging threat interpretations.     

Eveningness and Seasonality are Associated with the Bipolar Disorder Vulnerability Trait

Trait theories of vulnerability to bipolar disorder (BD) are increasingly common in the literature, yet poorly understood. The aim of the current study was to complement existing knowledge of trait theories by investigating two biological rhythm features often associated with BD – eveningness and seasonality – in a sample assessed as vulnerable to the disorder. Two hundred and thirteen participants completed an online survey consisting of the General Behavior Inventory, Seasonal Pattern Assessment Questionnaire, and Morningness-Eveningness Questionnaire. Hierarchical regressions controlling for sex and age showed that greater levels of seasonality and a tendency towards an eveningness chronotype were weak, but significant predictors of the BD vulnerability trait. When the traits of vulnerability to depression and mania were investigated separately, seasonality and eveningness were significant predictors of the former, but only seasonality was a significant predictor of the latter. The Autumn/Winter pattern of seasonality was a weak predictor of trait vulnerability to mania but not depression. The current findings advance understanding of the BD vulnerability trait, and may have consequences for the behavioural management of those who are considered to be ‘at risk’ of the disorder.     

Frontotemporal neural systems supporting semantic processing in Alzheimer’s disease

We hypothesized that semantic memory for object concepts involves both representations of visual feature knowledge in modality-specific association cortex and heteromodal regions that are important for integrating and organizing this semantic knowledge so that it can be used in a flexible, contextually appropriate manner. We examined this hypothesis in an fMRI study of mild Alzheimer’s disease (AD). Participants were presented with pairs of printed words and asked whether the words matched on a given visual–perceptual feature (e.g., guitar, violin: SHAPE). The stimuli probed natural kinds and manufactured objects, and the judgments involved shape or color. We found activation of bilateral ventral temporal cortex and left dorsolateral prefrontal cortex during semantic judgments, with AD patients showing less activation of these regions than healthy seniors. Moreover, AD patients showed less ventral temporal activation than did healthy seniors for manufactured objects, but not for natural kinds. We also used diffusion-weighted MRI of white matter to examine fractional anisotropy (FA). Patients with AD showed significantly reduced FA in the superior longitudinal fasciculus and inferior frontal-occipital fasciculus, which carry projections linking temporal and frontal regions of this semantic network. Our results are consistent with the hypothesis that semantic memory is supported in part by a large-scale neural network involving modality-specific association cortex, heteromodal association cortex, and projections between these regions. The semantic deficit in AD thus arises from gray matter disease that affects the representation of feature knowledge and processing its content, as well as white matter disease that interrupts the integrated functioning of this large-scale network.     

The Effects of Social and Physical Functioning and Self-Management Abilities on Well-Being Among Patients with Cardiovascular Diseases,Chronic Obstructive Pulmonary Disease,and Diabetes

To increase our understanding of relationships between well-being and social/physical functioning and self-management abilities (SMAs) among chronically ill patients. The cross-sectional questionnaire-based study included 1,254 patients with cardiovascular diseases, 725 with chronic obstructive pulmonary disease, and 253 with diabetes (total, 2232/4200; 53 % response rate). Social and physical functioning correlated significantly with SMAs and well-being (all p?≤?0.001). After controlling for background characteristics, multiple regression showed that social and physical functioning were still related to SMAs (β?=?0.32–0.12; both p?≤?0.001) and well-being (β?=?0.39–0.14; both p?≤?0.001). The strengths of relationships between well-being and social (β?=?0.39 vs. 0.20) and physical (β?=?0.14 vs. 0.07) functioning declined significantly (both p?≤?0.001) when the SMA mediator was included in the equation. SMAs of chronically ill are related to their social and physical functioning. We found indications that chronically ill patients reporting lower levels of social and physical functioning are worse self-managers than are those with higher levels of functioning. Furthermore, SMAs may mediate the relationships between social and physical functioning and well-being. Self-management interventions aiming to enhance SMAs more broadly than traditional interventions aiming only to prevent functional decline are expected to improve SMAs and enhance well-being among chronically ill patients.     

Repetition blindness reveals differences between the representations of manipulable and nonmanipulable objects

We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.

THE BIG FIVE PERSONALITY TRAITS, GENERAL MENTAL ABILITY, AND CAREER SUCCESS ACROSS THE LIFE SPAN

The present study investigated the relationship of traits from the 5-factor model of personality (often termed the "Big Five") and general mental ability with career success. Career success was argued to be comprised of intrinsic success (job satisfaction) and extrinsic success (income and occupational status) dimensions. Data were obtained from the Intergenerational Studies, a set of 3 studies that followed participants from early childhood to retirement. The most general findings were that conscientiousness positively predicted intrinsic and extrinsic career success, neuroticism negatively predicted extrinsic success, and general mental ability positively predicted extrinsic career success. Personality was related to career success controlling for general mental ability and, though adulthood measures of the Big Five traits were more strongly related to career success than were childhood measures, both contributed unique variance in explaining career success.     

Neurocognitive Function and Suicide in U.S. Army Soldiers

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk.     

Factors related to life satisfaction among urban African American adults receiving care at a publicly-funded sexual health clinic

Life satisfaction is linked to premature morbidity and mortality and it may be compromised for individuals living in economically-disadvantaged, urban neighborhoods. The present study explores how behavioral and social-environmental health factors are associated with life satisfaction among a sample of African American young adults. Participants (N = 307, M_age = 26.6 years, 53% male) were recruited from a publicly-funded clinic for a randomized controlled trial (RCT). Data from the baseline assessment of the RCT, which included measures of sleep, depression, anxiety, social support, alcohol and drug use problems, city stress, and life satisfaction, were used for the current study. Correlation analyses assessed bivariate associations between life satisfaction and the demographic and health-related factors. Linear regression using backward elimination determined the best fitting model of factors associated with life satisfaction. Backward elimination resulted in the following variables remaining as significantly associated with life satisfaction: age (b = ?2.40, p = .017), anxiety (b = ?5.32, p < .001), and social support (b = 2.89, p = .004). Feeling rested upon waking also remained in the best fitting model, although this association did not achieve statistical significance (p = .099). The results suggest that African American adults who are younger, less anxious, and report adequate social support are more likely to report satisfaction with life. These findings add to the literature aimed at examining health and social factors impacting the well-being of African Americans living in low-income, urban communities.     

Positive Mental Health as a Predictor of Problematic Internet and Facebook Use in Adolescents and Young Adults

Recent research on Problematic Internet Use and Problematic Facebook Use (PIU and PFU) has focused on the idea that people who engage in PIU or PFU are more likely to present with mental health problems. The goal of the present study was to examine the contribution of positive mental health (PMH) to PIU and PFU among adolescents and young adults. A total of 1927 Italian adolescents and young adults participated in the study. Structural equation modeling showed that PMH is negatively linked to both PIU and PFU, indicating that PMH may be an important antecedent for both PIU and PFU among adolescents and young adults. In conclusion, dimensions of PMH may be taken into account by researchers and educational practitioners in preventing both PIU and PFU.
