Obsessive beliefs predict cognitive behavior therapy outcome for obsessive compulsive disorder

Cognitive accounts of obsessive compulsive disorder (OCD) assert that core beliefs are crucial to the development, maintenance, and treatment of the disorder. There are a number of obsessive beliefs that are considered fundamental to OCD, including personal responsibility, threat estimation, perfectionism, need for certainty, importance of thoughts, and thought control. The present study investigated if pretreatment severity of obsessive beliefs, as well as the change in obsessive beliefs following treatment, predicted intensive, residential cognitive behavioral therapy (CBT) treatment outcome. A series of hierarchical regression analyses were carried out to investigate the relations between obsessive beliefs and treatment outcome. Results indicated that inflated pretreatment responsibility/threat estimation beliefs were significantly related to less overall obsessive compulsive (OC) symptom reduction at discharge, explaining 2% of the overall variance. Changes in obsessive beliefs broadly, and importance/control of thoughts specifically, were positively related to overall OC symptom reduction at discharge, respectively explaining 18% and 3.6% variance. Results are modestly consistent with a number of theoretical models, which argue that inflated responsibility, threat estimation, and thought control are important to the maintenance and treatment of OCD.     

Component analysis of simple span vs. complex span adaptive working memory exercises: A randomized,controlled trial

There has been growing interest in using adaptive training interventions such as Cogmed-RM to increase the capacity of working memory (WM), but this intervention may not be optimally designed. For instance, Cogmed-RM can target the primary memory (PM) component of WM capacity, but not the secondary memory (SM) component. The present study hypothesized that Cogmed-RM does not target SM capacity because the simple span exercises it uses may not cause a sufficient amount of information to be lost from PM during training. To investigate, we randomly assigned participants to either a standard (simple span; N = 31) or a modified (complex span; N = 30) training condition. The main findings showed that SM capacity did not improve, even in the modified training condition. Hence, the potency of span-based WM interventions cannot be increased simply by converting simple span exercises into complex span exercises.     

The Surveyability of Mathematical Proof: A Historical Perspective

This paper rejoins the debate surrounding Thomas Tymockzko’s paper on the surveyability of proof, first published in the Journal of Philosophy, and makes the claim that by attending to certain broad features of modern conceptions of proof we may understand ways in which the debate surrounding the surveyability of proof has heretofore remained unduly circumscribed. Motivated by these historical reflections, I suggest a distinction between local and global surveyability which I believe has the promise to open up significant new advances in the philosophy of mathematics.     

Measuring, monitoring and managing the psychological well-being of first year university students

This paper profiles the psychological well-being of students in their initial year of university. There were three aims: to measure the impact of arrival at university on the psychological well-being of first year students, to monitor (i.e. profile) the shape of psychological well-being across the first year, and to investigate how students manage their well-being in relation to the use of university counselling services. Data were collected on four occasions, with 84% of all first year students at a UK university (4,699 students) completing the questionnaire on at least one occasion. Psychological well-being was assessed using the GP-CORE, a general population form of the CORE-OM. Results show that greater strain is placed on well-being once students start university compared to levels preceding entry. This strain rises and falls across the year but does not return to pre-university levels. Items tapping depression and anxiety suggest that the first year of university is a time of heightened anxiety but not a particularly depressive time. The findings are discussed in relation to students' experience of higher education and how to match student needs with university counselling service provision.     

Sex-Dimorphic Color Preference in Children with Gender Identity Disorder: A Comparison to Clinical and Community Controls

The present study was designed to assess sex-dimorphic color preferences in children with gender identity disorder (47 boys, 18 girls), clinical controls (65 boys, 35 girls), and community controls (65 boys, 35 girls). The mean age of the children was 7.63 years (range?=?3–12 years). Children were shown a hexagon-shaped display of 144 colors extracted from PowerPoint?. Each child was asked to choose his or her three favorite colors (Trials 1–3) by pointing to them, naming them, and then to provide a justification for each choice. From the entire array, children labeled a total of 11 different colors: black, blue, brown, gray, green, orange, pink, purple, red, white, and yellow. For three of the colors (blue, pink/purple, and red), there was evidence for normative sex differences in color preference, and, for the colors blue and pink/purple, the gender-referred children showed inverted patterns of color preference. For the color blue, luminance values showed that the gender-referred boys and control girls preferred lighter shades, whereas the gender-referred girls and control boys preferred darker shades. Qualitative analysis indicated that gender-specific justifications were uncommon, even for the sex-dimorphic colors. Gender-referred children showed inverted gender-stereotyped color preferences, which are likely related to their more general pattern of cross-gender identification. Principles of gender-differentiated development derived from gender-schema theory are used to explain the group differences in color preferences.     

Two Concepts of Intrinsic Value

Recent literature on intrinsic value contains a number of disputes about the nature of the concept. On the one hand, there are those who think states of affairs, such as states of pleasure or desire satisfaction, are the bearers of intrinsic value (“Mooreans”); on the other hand, there are those who think concrete objects, like people, are intrinsically valuable (“Kantians”). The contention of this paper is that there is not a single concept of intrinsic value about which Mooreans and Kantians have disagreed, but rather two distinct concepts. I state a number of principles about intrinsic value that have typically (though not universally) been held by Mooreans, all of which are typically denied by Kantians. I show that there are distinct theoretical roles for a concept of intrinsic value to play in a moral framework. When we notice these distinct theoretical roles, we should realize that there is room for two distinct concepts of intrinsic value within a single moral framework: one that accords with some or all of the Moorean principles, and one that does not.     

Development of the Measure of Adaptations for Pelvic Symptoms (MAPS): the Importance of Incorporating the Female Patient’s Voice

Women with pelvic floor disorders use many adaptations in an attempt to minimize symptoms and enhance the quality of their lives. Existing condition-specific measures fail to capture the extent or impact of these adaptive behaviors. The present paper seeks to extend the women’s health literature and expand the registry of available measures to assess pelvic floor disorders by: 1) documenting the steps taken in the development and initial validation of the Measure of Adaptations for Pelvic Symptoms (MAPS); and 2) describing the added value of incorporating the patient’s voice in the instrument development process through in-depth focus groups. The rigorous process used to develop the measure (i.e., literature review, clinical experts, anecdotal patient reports, telephone-administered pilot study, and focus groups with female patients) is described. Analysis of the focus group data yielded eight important adaptation themes used to further refine the MAPS: disclosure, seclusion, being prepared, planning, clothing considerations, sexuality, order and intensity, and outlook. Specifically, focus group participants confirmed the use of sanitary pads and limiting food and beverage consumption. Women did not endorse keeping a jar or commode nearby. Discussions yielded important modifications to items about restroom use, clothing preferences, “survival kits” and “informal” pessary use. Participants described social isolation and preparations for sexual relations that led to new items. This study confirmed the value of incorporating women’s voices in the questionnaire development process through in-depth focus groups. The process revealed important patient experiences and led to significant refinements of the final measure.     

Long-term memory in pigeons: I. The role of discrimination problem difficulty assessed by reacquisition measures II. The role of stimulus modality assessed by generalization slope

Pigeons learned either an easy or a difficult line angle discrimination (Experiment 1) or wavelength discrimination (Experiment 2), and then they were given a reacquisition test of retention after delays of 1 min, 1 day, or 1 week. Both percentage of responses to the S+ in the initial 10-trial block and number of blocks to criterion showed a progressive memory loss which was greater for the difficult problem. These results extend recent findings by using a free operant rather than a discrete trial task and by varying problem difficulty by altering the dimensional separation between training stimuli. In Experiment 3, pigeons were given variable interval training with either a wavelength or a line angle stimulus, and then they were tested for generalization in extinction after delays of 1 min, 1 day, and 1 week. With both dimensions, the relative gradients became progressively flatter with increasing delay intervals. This replicates earlier findings and extends them to the line angle dimension. The evidence of substantial forgetting in the first 24 h in all three experiments suggests that operant free-response procedures are more sensitive to forgetting effects than are discrete trial tasks.     

Yale Children's Inventory (YCI): An instrument to assess children with attentional deficits and learning disabilities I. Scale development and psychometric properties

The Yale Children's Inventory (YCI), a parent based rating scale, and the scales derived from it have been developed to identify and measure multiple dimensions of learning disabilities with particular emphasis on attentional deficits. Scale construction was based on factor analytic procedures. Measures of internal consistency, test retest reliability, and coefficients of congruence support the reliability and stability of the 11 scales. A discriminant function classified normal and learning disabled children with a relatively high rate of accuracy. The relationship and content of the three relevant YCI scales were compared to the DSM-III diagnostic categories for ADD. As operationalized, DSM-III criteria for hyperactivity formed a cohesive factor, while criteria for attention and impulsivity were not distinguishable from each other since they loaded together on a single factor. In contrast, the equivalent YCI scales for attention, impulsivity, and hyperactivity were found to be distinct.
