Truth and Tension in Science and Religion

While evolution deserves theological support and inclusion in schools, the consensus views, Darwinian or neo-Darwinian evolution, present problems. Darwin presented two arguments: 1) that evolution, descent with modification, has occurred, and 2) that its “cause” is natural selection, the focus of neo-Darwinism. However, the products of natural selection, adaptations, are often not congruent with the lineages produced by evolution and its demonstrated effects are within species. The difficulty of using natural selection to explain evolution is used by proponents of Intelligent Design (ID) to denigrate evolution and to argue for the inclusion of ID in biology classes. However, the force of the arguments in favor of ID disappear when evolution is viewed as an informational phenomenon. Evolution, like development, is a system of increasing complexity, and emergence the inevitable outcome of the transformation of matter whereby the information in DNA is expressed that accompanies energy dynamics. Evolution is witnessed by studies in comparative biology that reveal groups of related organisms and homologies, both the result of descent with modification.     

The enemy within An exploration of the concept of boundaries in a GP's surgery

Abstract

This paper looks at two GPs' surgeries and the way that they deal with the anxieties aroused when trying to meet patients' needs in primary health care. The practice counsellor is both an observer and a participant in this. The physical surroundings seem to influence the way these anxieties are acted out. Each surgery has to create an enemy in order to live with their anxiety.     

Assessing the Relationship Between Differentiation and Infidelity

SUMMARY

Differentiation and infidelity have been theoretically related. However, few studies have tested whether the concepts in differentiation are statistically related to infidelity. One hundred nineteen participants in the present study completed two inventories assessing their level of differentiation and engaging in infidelity. Two-step structural equation modeling is used to determine the degree to which differentiation relates to infidelity. Results indicated that, though differentiation may be part of a plausible model of infidelity behavior, there are potentially other models that may be relevant in engaging in infidelity. The findings and implications are discussed.     

A Preliminary Investigation of the Effects of Reading Fluency Interventions on Comprehension

Abstract

Brief experimental analyses were conducted using two dependent variables to evaluate the effectiveness of reading interventions. Specifically reading rate (words read correctly per minute) and mean reading comprehension levels for six students with reading difficulties were obtained using six different reading intervention/intervention combinations. These interventions included contingent reinforcement, listening passage preview, repeated reading, listening passage preview with contingent reinforcement, repeated reading with contingent reinforcement, and repeated reading with listening passage preview. Results suggested that no one intervention was best for all students. In addition, it was found that interventions that increased reading rate for half of the students also increased reading comprehension for the same students. Discussion focuses on student-treatment interactions, measuring student reading performance, matching treatments to students, and directions for future research.     

Cognitive Behavioural Therapy and Applied Relaxation for Generalized Anxiety Disorder: A Time Series Analysis of Change in Worry and Somatic Anxiety

The present study examined symptom change profiles in patients with generalized anxiety disorder (GAD) receiving either cognitive behavioural therapy (CBT) or applied relaxation (AR). It was hypothesized that (a) changes in worry would uniquely predict changes in somatic anxiety for most participants receiving CBT and (b) changes in somatic anxiety would uniquely predict changes in worry for most participants in the AR condition. Twenty participants (CBT n = 10; AR n = 10) completed daily ratings of worry and somatic anxiety during therapy, and multivariate time series analysis was used to assess the causal impact of each variable on the other. The hypotheses were not supported because we found no evidence of a match between individual symptom change profiles and treatment condition. Rather, a bidirectional relationship between worry and somatic anxiety was observed in 80% of participants receiving CBT and 70% of participants receiving AR. When only treatment responders were considered, 83% of participants receiving CBT and 86% of those receiving AR had such a bidirectional effect. The findings are discussed in terms of models of psychopathology that posit dynamic interactions between symptom clusters and in terms of the value of examining treatment mechanisms at the individual level.     

Assessing the Relationship Between Cold Pressor Pain Responses and Dimensions of the Anxiety Sensitivity Profile in Healthy Men and Women

Anxiety sensitivity (AS) has been shown previously to be an important factor in the perception and experience of experimentally induced pain within healthy adults. The aim of the current study was to extend this research by: (i) using the Anxiety Sensitivity Profile (ASP) as an alternative measure of AS; (ii) examining whether different coping instructions affect pain reports; and (iii) investigating potential differences between men and women. Participants were 50 healthy adults (23 males, 27 females) who were required to complete 2 versions of the cold pressor pain task; one version required the use of control instructions, whereas the other made use of acceptance‐based instructions. Although the coping instructions were found to affect pain thresholds (acceptance resulted in lower thresholds), a similar pattern of correlations were found between the pain indexes and AS under both conditions. Of the ASP subscales, the gastrointestinal and cognitive concerns components were found to be the most strongly related to pain experiences. When the analysis was conducted separately for each sex, the ASP scales were related to the self‐report measures of pain in women, whereas they were related to the behavioural measures of pain in men. These results not only confirm that AS is associated with experimental pain, but that there may be sex differences in this relationship.     

Interoceptive Exposure Therapy Combined with Trauma‐related Exposure Therapy for Post‐traumatic Stress Disorder: a Case Report

Trauma‐related exposure therapy is a useful but not universally effective treatment for post‐traumatic stress disorder. Anxiety sensitivity may play an important role in this disorder, as it does in panic disorder. Studies have shown that interoceptive exposure therapy reduces anxiety sensitivity in panic disorder. The present case study was a preliminary investigation of the merits of including interoceptive exposure therapy in the treatment of post‐traumatic stress disorder, in order to improve treatment outcome for a patient who had no history of panic disorder or panic attacks. Interoceptive exposure therapy (4 sessions) was one component of treatment, combined with trauma‐related exposure therapy (4 sessions of imaginal exposure followed by 4 sessions of in vivo exposure). Treatment outcome was assessed with the Clinician‐Administered Post‐traumatic Stress Disorder Scale, a self‐report measure of post‐traumatic stress disorder symptoms, and measures of symptoms and cognitions commonly associated with post‐traumatic stress disorder. Scores on all outcome measures decreased over the course of treatment, with gains maintained at 1‐ and 3‐month follow‐up. Symptoms of anxiety sensitivity and post‐traumatic stress disorder decreased during interoceptive exposure therapy. The results indicate that interoceptive exposure therapy is a promising adjunctive intervention for post‐traumatic stress disorder. Further research is needed into the merits of combining interoceptive exposure therapy and trauma‐related exposure therapy as a means of boosting treatment efficacy.     

Cognitive Factors that Maintain Social Anxiety Disorder: a Comprehensive Model and its Treatment Implications

Social anxiety disorder (SAD) is a common, distressing and persistent mental illness. Recent studies have identified a number of psychological factors that could explain the maintenance of the disorder. These factors are presented here as part of a comprehensive psychological maintenance model of SAD. This model assumes that social apprehension is associated with unrealistic social standards and a deficiency in selecting attainable social goals. When confronted with challenging social situations, individuals with SAD shift their attention toward their anxiety, view themselves negatively as a social object, overestimate the negative consequences of a social encounter, believe that they have little control over their emotional response, and view their social skills as inadequate to effectively cope with the social situation. In order to avoid social mishaps, individuals with SAD revert to maladaptive coping strategies, including avoidance and safety behaviors, followed by post‐event rumination, which leads to further social apprehension in the future. Possible disorder‐specific intervention strategies are discussed.     

Anxiety Sensitivity Taxonicity: a Concurrent Test of Cognitive Vulnerability for Post‐Traumatic Stress Symptomatology Among Young Adults

This study evaluated the anxiety sensitivity taxon using the 16‐item Anxiety Sensitivity Index in relation to 2 criteria relevant to post‐traumatic stress disorder; post‐traumatic stress disorder symptom severity as indexed by the Post‐Traumatic Diagnostic Scale, and post‐traumatic cognitions as indexed by the Post‐Traumatic Cognitions Inventory. Taxometric analyses of data collected from 331 young adults indicated that the latent structure of anxiety sensitivity was taxonic with an estimated base‐rate range of 11–12%. As predicted, an 8‐item Anxiety Sensitivity Index Taxon Scale accounted for significant variance above and beyond that accounted for by negative affectivity and the full‐scale Anxiety Sensitivity Index total score in terms of both criteria. Moreover, after accounting for variance explained by the full‐scale Anxiety Sensitivity Index total score and negative affectivity, the sum score for the 8 Anxiety Sensitivity Index items not included in the Anxiety Sensitivity Index Taxon Scale was associated with significant variance in these same dependent measures, but the relation was in the opposite direction to that predicted by theory. These findings are discussed in terms of theoretical and clinical implications for the study of anxiety sensitivity and post‐traumatic stress disorder vulnerability.     

Distress and Avoidance in Generalized Anxiety Disorder: Exploring the Relationships with Intolerance of Uncertainty and Worry

Theory and research suggest that treatments targeting experiential avoidance may enhance outcomes for patients with generalized anxiety disorder (GAD). The present study examined the role of experiential avoidance and distress about emotions in a treatment-seeking sample with a principal diagnosis of GAD compared with demographically matched nonanxious controls and sought to explore their shared relationship with two putative psychopathological processes in GAD: intolerance of uncertainty and worry. Patients with GAD reported significantly higher levels of experiential avoidance and distress about emotions compared with nonclinical controls while controlling for depressive symptoms, and measures of these constructs significantly predicted GAD status. Additionally, experiential avoidance and distress about anxious, positive, and angry emotions shared unique variance with intolerance of uncertainty when negative affect was partialed out, whereas only experiential avoidance and distress about anxious emotions shared unique variance with worry. Discussion focuses on implications for treatment as well as future directions for research.
