Generalized Worry in Patients With Chronic Fatigue Syndrome Following Cognitive Behavioral Therapy: A Prospective Cohort Study in Secondary Care

Research has shown that generalized anxiety disorder is commonly associated with Chronic Fatigue Syndrome (CFS). This prospective cohort study aimed to investigate the prevalence of generalized worry in CFS patients and its relationship with fatigue, anxiety and social functioning, before and after Cognitive Behavioral Therapy (CBT). Our cohort consisted of 470 patients diagnosed with CFS who received CBT at a secondary care, specialist clinic. Patients completed self-report measures investigating levels of generalized worry, fatigue, work and social adjustment, anxiety and depression at baseline (pretreatment), discharge from treatment, 3-month and 6-month follow up (posttreatment). Analysis indicated a high prevalence of generalized worry (72.4%) at assessment. A significant reduction in worry following CBT (M = −3.42, p < .001, 95% CIs: 2.26, 4.57) was observed at discharge, which remained stable at follow-up. Severe baseline worriers had greater overall fatigue score (M = 3.74, p = .026, 95% CIs: .33, 7.15) and worse overall work and social adjustment than mild worriers across time-points (M = 5.42, p = .035 95% CIs: .27, 10.58). Avoidance behavior mediated the association between generalized worry and work and social adjustment (95% bootstrap CIs: 013, .080). The majority of patients with CFS had comorbid generalized worry and severe worriers reported greater fatigue, anxiety, and worse work and social adjustment. This suggests that CFS patients may benefit from targeting generalized worry during CBT.     

An Irish Cohort Study of Risk and Protective Factors for Infant Language Development at 9 Months

This nationally representative study of Irish infants explores whether the set of child and environmental factors established as predicting language outcomes aged 3 years would also predict language and communication development as early as age 9 months. Associations between infant and environmental characteristics and infant language outcomes at 9 months, as measured on the ASQ 10‐month communication questionnaire, were explored in a series of bivariate logistic regression models and in a fully adjusted multivariable logistic regression model. Infant gender, health, birthweight and temperament were significantly associated with passing the ASQ communication measure at 9 months. Being an only child and having some experience of relative childcare predicted positive communication outcomes. Infants of older mothers and mothers who spoke less to the child while doing other things were significantly less likely to pass. Infants of mothers with the lowest educational level were more likely than their peers to pass at 9 months. Unlike language outcomes at 3 years, low maternal education does not appear to be a risk factor for poorer outcomes at 9 months. This study adds significantly to the infant language development literature by focussing on communication outcomes in early infancy and identifying protective and risk factors at such an early stage.

Divine Omniscience: Is God's Foreknowledge at Risk in the Context of Contemporary Science?

Abstract

Does quantum indeterminacy threaten the classical theological doctrine of divine omniscience? Certain popular interpretations of quantum physics have challenged conventional ways of thinking about time and space, being and becoming. Consequently, the traditional doctrine that God knows all things, including future contingent events, has recently come under debate. This paper explores how the way we think about time affects the way we think about God's relation to time. Theologians need to be careful when appropriating scientific theories in their theological reflections because interpretations of those theories often bring along unnecessary metaphysical presuppositions. Using an interpretation of special relativity that focuses on the Lorentz transformation, this paper shows that modern physics does not truly challenge the doctrine of divine foreknowledge. In fact, modern physical theories can actually deepen theological reflection on the classical doctrine of divine omniscience.     

African-American Partisanship and the Legacy of the Civil Rights Movement: Generational, Regional, and Economic Influences on Democratic Identification, 1973–1994

We explore the importance of generational effects and the changing economic circumstances of Blacks to explain variations over time in the partisan attachments of African Americans. More specifically, we explore whether generational differences have caused the cohorts that came of political age following the Civil Rights movement to be less Democratic than generations that lived through the Civil Rights movement and its aftermath. We find that while life-cycle effects explain a portion of the movement away from the two major parties, generational effects account for the small but significant increase in Republican party identification in the youngest generation. Additionally, living in the South accounts for the steepest gains in political independence. Finally, changing economic influences over time appear to have led poorer Blacks to change from the most likely to the least likely to identify with a major party.     

Decreased load on general motor preparation and visual-working memory while preparing familiar as compared to unfamiliar movement sequences

Learning movement sequences is thought to develop from an initial controlled attentive phase to a more automatic inattentive phase. Furthermore, execution of sequences becomes faster with practice, which may result from changes at a general motor processing level rather than at an effector specific motor processing level. In the current study, we examined whether these changes are already present during preparation. Fixed series of six keypresses, either familiar or unfamiliar, had to be prepared and executed/withheld after a go/nogo signal. Reaction time results confirmed that familiar sequences were executed faster than unfamiliar sequences. Results derived from the electroencephalogram showed a decreased demand on general motor preparation and visual-working memory before familiar sequences as compared to unfamiliar sequences. We propose that with familiar sequences the presetting segments of responses is less demanding than with unfamiliar sequences, as familiar sequences can be regarded as less complex than unfamiliar sequences. Finally, the decreasing demand on visual-working memory before familiar sequences suggests that sequence learning indeed develops from an attentive to an automatic phase.     

Correlation and explaining variance: To square or not to square?

Despite previous articles dating back 80 years, the questions of whether and when to square correlations continue to puzzle and confuse researchers. In this editorial, I point out that correlations can serve two independent purposes: they can be measures of effect size in themselves and their function as regression coefficients can be used to estimate proportion of variance in one measure for which another measure accounts. Using examples relevant to intelligence researchers, I show that the answer to the question of whether or not to square a correlation is ‘it depends.’ It depends on the purpose and it depends on the underlying theoretical model of the causal association between the variables.     

Are you a “bad driver” all the time? Insights from a weekly diary study on personality and dangerous driving behavior

Research concerning dangerous driving behavior has often favored studying inter-individual differences at the expense of intra-individual ones (especially when verifying its associations with personality factors). Using a 7 weeks diary approach, we aimed at exploring the intra-individual variation of dangerous driving behavior (Errors, Violations and Aggressive driving). Also, we verified if our outcomes could be predicted by both situational variables (weekly km, felt traffic pressure and traffic mood) and dispositional ones (Big-Five personality factors, age and gender). Our findings revealed that Violations, Verbal & Physical aggression and Vehicle aggression had similar intra- to inter-individual variation ratios, with approximately 45% of variance at the intra-individual level. In contrast, Errors had only about 30% of variance at the intra-individual level. Traffic mood was the only significant intra-individual predictor, negatively correlating with all outcomes. Excepting Agreeableness, all personality factors were related to at least one dangerous driving behavior (especially consistent for the association between Extraversion and Aggressive driving). Also, women reported lower levels than men on all outcomes but Errors. Overall, this study raises some questions about the assumed stability of driving behavior, while at the same time confirming several relational patterns between personality factors and dangerous driving.     

Mapping from Sound to Meaning: Reduced Lexical Activation in Broca''s Aphasics

Recent studies of lexical access in Broca's aphasics suggest that lexical activation levels are reduced in these patients. The present study compared the performance of Broca's aphasics with that of normal subjects in an auditory semantic priming paradigm. Lexical decision times were measured in response to word targets preceded by an intact semantically related prime word ("cat"-"dog"), by a related prime in which one segment was acoustically altered to produce a poorer phonetic exemplar ("c*at"-"dog"), and by a semantically unrelated prime ("ring"-"dog"). The effects of the locus of the acoustic distortion within the prime word (initial or final position) and the presence of potential lexical competitors ("cat" --> /gaet/versus "coat" --> "goat") were examined. In normal subjects, the acoustic manipulations produce a small, short-lived reduction in semantic facilitation irrespective of the position of the distortion in the prime word or the presence of a voiced lexical competitor. In contrast, Broca's aphasics showed a large and lasting reduction in priming in response to word-initial acoustic distortions, but only a weak effect of word-final distortions on priming. In both phonetic positions, the effect of distortion was greater for prime words with a lexical competitor. These findings are compatible with the claim that Broca's aphasics have reduced lexical activation levels, which may result in a disruption of the bottom-up access of words on the basis of acoustic input as well as increased vulnerability to competition between acoustically similar lexical items.     

When is search for meaning in life beneficial for well-being? A cross-national study

Previous research has found cross-national variations in the association between search for meaning in life (SMIL) and well-being (i.e. SMIL–WB link). This study extended and tested a “self-improvement hypothesis” that accounts for such cross-national variations based on an international database—the sixth wave of World Values Survey. SMIL represents a self-improvement effort which is more demanded in contexts with stronger external constraints. Thus, we expected a stronger positive SMIL–WB link in such contexts. A series of multilevel analyses was used to verify this hypothesis. The results showed that the SMIL–WB link varied across different societies, with well-being indexed by happiness, life satisfaction and subjective health. Moreover, external constraints from cultural, social-institutional, economic and ecological contexts (collectivism, peace threats, economic scarcity and environmental threats) moderated the SMIL–WB links. We thus call for advancing SMIL theory by considering person–context interaction.     

One country,two cultures: Implicit space–time mappings in Southern and Northern Vietnamese

What determines how people implicitly associate the “past” and “future” with “front” and “back”? According to the Temporal Focus Hypothesis (TFH), people's cultural attitudes toward time influence their implicit space–time mappings. However, previous research mainly used cross‐cultural comparison in which the cultures compared differ not only in attentional focus on temporal events, but may also differ in other cultural values. Thus, the specific role of cultural attitudes toward time has not been tested. In the current study, we compared Southern and Northern Vietnamese who have many aspects in common but demonstrate cultural differences in attitudes toward the past and future. The results showed that the two groups of participants tended to think about time according to their temporal focus. Taken together, this pattern of results showed that within‐cultural differences in temporal focus can also predict variation in space–time mappings, which provides further supporting evidence for the TFH.
