Perseverative thought: a robust predictor of response to emotional challenge in generalized anxiety disorder and major depressive disorder

Generalized anxiety disorder (GAD) and major depressive disorder (MDD) frequently co-occur, yet the reasons for their comorbidity remain poorly understood. In the present experiment, we tested whether a tendency to engage in negative, repetitive thinking constitutes a common risk process for the two disorders. A mixed sample of adults with comorbid GAD–MDD (n = 50), GAD only (n = 35), MDD only (n = 34), or no lifetime psychopathology (n = 35) was administered noncontingent failure and success feedback on consecutive performance tasks. Perseverative thought (PT), measured by negative thought intrusions during a baseline period of focused breathing, emerged as a powerful prospective predictor of responses to this experimental challenge. Participants reporting more frequent negative thought intrusions at baseline, irrespective of thought content or diagnostic status, exhibited a stronger negative response to failure that persisted even after subsequent success. Higher PT over the course of the experiment was associated with later behavioral avoidance, with negative affect and other traits closely linked to anxiety and depression, and with the presence and severity of GAD and MDD. These findings provide evidence for a broadly-defined PT trait that is shared by GAD and MDD and contributes to adverse outcomes in these disorders.     

A meta-analysis of the effect of cognitive bias modification on anxiety and depression

Cognitive biases have been theorized to play a critical role in the onset and maintenance of anxiety and depression. Cognitive bias modification (CBM), an experimental paradigm that uses training to induce maladaptive or adaptive cognitive biases, was developed to test these causal models. Although CBM has generated considerable interest in the past decade, both as an experimental paradigm and as a form of treatment, there have been no quantitative reviews of the effect of CBM on anxiety and depression. This meta-analysis of 45 studies (2,591 participants) assessed the effect of CBM on cognitive biases and on anxiety and depression. CBM had a medium effect on biases (g = 0.49) that was stronger for interpretation (g = 0.81) than for attention (g = 0.29) biases. CBM further had a small effect on anxiety and depression (g = 0.13), although this effect was reliable only when symptoms were assessed after participants experienced a stressor (g = 0.23). When anxiety and depression were examined separately, CBM significantly modified anxiety but not depression. There was a nonsignificant trend toward a larger effect for studies including multiple training sessions. These findings are broadly consistent with cognitive theories of anxiety and depression that propose an interactive effect of cognitive biases and stressors on these symptoms. However, the small effect sizes observed here suggest that this effect may be more modest than previously believed.     

The end justifies the means, but only in the middle

Achieving goals often requires the completion of sequential actions, such as finishing a series of assignments to pass a class. In the course of pursuing such goals, people can decide how closely to follow their personal standards for each action. We propose that actions at the beginning and end of a sequence appear more diagnostic of the pursuer's personal standards than do actions in the middle. Therefore, people are more likely to adhere to their standards at the beginning and end of goal pursuit-and slack in the middle. We demonstrate this pattern of judgment and behavior in adherence to ethical standards (e.g., cheating), religious traditions (e.g., skipping religious rituals), and performance standards (e.g., "cutting corners" on a task). We also show that the motivation to adhere to standards by using proper means is independent and follows a different pattern from the motivation to reach the end state of goal pursuit.     

What we talked about at the pediatrician's office: Exploring differences between healthy steps and traditional pediatric primary care visits

Healthy Steps for Young Children (HS) is a program designed to enhance pediatric primary care experiences for children birth to 3 years and their families by pairing a developmental specialist with a pediatric provider during well‐child visits. This study examined the impact of HS on content discussed during well‐child visits by providers, HS Specialists, and families. The impact of HS on pediatric outcomes, including timeliness of well‐child visits and immunizations, also was examined. Using retrospective medical review, records of 40 children enrolled in HS were compared with records of 36 demographically matched controls. A developmental topics checklist was used to analyze content of well‐child visits. Attendance at well‐child visits, receipt of immunizations, and healthcare utilization also was evaluated. Important developmental topics were discussed more often during well‐child visits of children enrolled in HS than for children who were not enrolled. Children enrolled in HS received timelier well‐child visits and immunizations. No differences between groups were found in the number of sick or emergency room visits. Integrating HS Specialists into pediatric primary care well‐child visits allows for discussion of important developmental topics while also impacting pediatric health outcomes.     

Age-related changes in cognitive processing of moral and social conventional violations

Moral and conventional violations are usually judged differently: Only moral violations are treated as independent of social rules. To investigate the cognitive processing involved in the development of this distinction, undergraduates (N = 34), adolescents (N = 34), and children (N = 14) read scenarios presented on a computer that had 1 of 3 endings: moral violations, conventional violations, or neutral acts. Participants judged whether the act was acceptable or unacceptable in a condition in which social rules were assumed, or in a condition in which they imagined the absence of rules (rule-removed condition). At all ages reaction times (RTs) were faster for moral than conventional violations when a rule was assumed. RTs in the rule-removed condition were longer than in the rule-assumed condition, only for adults’ moral judgments. In addition to this age difference, adolescents made more normative judgments than children. These findings extend previous work by showing different time courses of processing conventional versus moral violations and revealing age-related differences in the tendency to make normative judgments.     

An extension of construct validity for personality scales using twin-based criteria

A twin-based analysis of personality inventory scales yields information relevant to construct validity. If scales validly measure dimensions influenced developmentally either by environmental factors common to cotwins or by genetic similarities, these influences should be apparent in patterns of intraclass correlations and within-pair variance ratios for monozygotic and dizygotic pairs. Criteria for construct validity derived from adolescent twin statistics are illustrated with Wiggins' MMPI Content Scales. A type of discriminant validity indicates that some scales are not distinct in terms of the influences of familial similarity. Sex differences are examined.     

Together or apart: when goals and temptations complement versus compete

This research examined how the presentation of items related to goals and temptations influences the dynamic of self-regulation, as reflected in evaluation and choice. The authors found that when items, such as healthy and unhealthy foods or academic and leisure activities, are presented together in a unified choice set (e.g., in 1 image) and seem to complement each other, people express a positive evaluation of and a preference for tempting items. Conversely, when the items are presented apart from each other in 2 choice sets (e.g., 2 images) and seem to compete with each other, people express a positive evaluation of and preference for goal items.     

Gender differences in unilateral spatial neglect within 24 hours of ischemic stroke

Hemispatial neglect is a common and disabling consequence of stroke. Previous reports examining the relationship between gender and the incidence of unilateral spatial neglect (USN) have included either a large numbers of patients with few neglect tests or small numbers of patients with multiple tests. To determine if USN was more common and/or severe in men or women, we examined a large group of patients (312 right-handed) within 24 hours of acute right hemisphere ischemic stroke. Multiple spatial neglect tasks were used to increase the sensitivity of neglect detection. No differences based upon gender were observed for the prevalence, severity, or a combined task measure of USN.
