Perceived Versus Predicted Risks of Colorectal Cancer and Self-Reported Colonoscopies by Members of Mismatch Repair Gene Mutation-Carrying Families Who Have Declined Genetic Testing

People carrying germline mutations in mismatch repair genes are at high risk of colorectal cancer (CRC), yet about half of people from mutation-carrying families decline genetic counselling and/or testing to identify mutation status. We studied the association of quantitative measures of risk perception, risk prediction and self-reported screening colonoscopy in this elusive yet high-risk group. The sample of 26 participants (mean age 43.1 years, 14 women) in the Australasian Colorectal Cancer Family Registry were relatives of mutation carriers; had not been diagnosed with any cancer at the time of recruitment and had declined an invitation to attend genetic counselling and/or testing. A structured elicitation protocol captured perceived CRC risk over the next 10 years. Self-reported colonoscopy screening was elicited during a 45-minute semi-structured interview. Predicted 10-year CRC risk based on age, gender, known mutation status and family history was calculated using “MMRpro.” Mean perceived 10-year risk of CRC was 31 % [95 % CI 21, 40], compared with mean predicted risk of 4 % [2, 7] (p?<?0.001); this was independent of age and sex (p?=?0.9). Among those reporting any medical advice and any screening colonoscopy (n?=?18), those with higher risk perception had less frequent colonoscopy (Pearson’s r?=?0.49 [0.02, 0.79]). People who decline genetic testing for CRC susceptibility mutations perceive themselves to be at substantially higher risk than they really are. Those with high perceived risk do not undertake screening colonoscopy more often than those who perceive themselves to be at average risk.     

“Clean and Fresh”: Understanding Women’s use of Vaginal Hygiene Products

We explore Canadian women’s use of vaginal hygiene products including feminine washes, douches, sprays, deodorants, wipes, and powders. Vaginal hygiene products in North America are part of a two billion dollar industry, which focuses on cleanliness and freshness in their advertising toward women. In interviewing women who were currently using or had previously used vaginal hygiene products, we found that vaginal cleanliness and freshness were also frequently brought up as reasons for using these products. Using an inductive thematic analysis informed by Braun and Clarke (2013) we explore how attaining a clean-and-fresh vagina has become a subjective physical need for the participants in our study. In a society where female genitalia are constructed as unclean, we argue the marketing of vaginal hygiene products contributes to the problematization of women’s genitalia by suggesting women need to use these products to attain an ideal (i.e., clean and fresh) vagina. The reliance on vaginal hygiene products reported by participants in attaining sensations of vaginal cleanliness and freshness raises concerns in the context of medical literature suggesting adverse health risks that may result from using some of these products. Potential risks include bacterial vaginosis, pelvic inflammatory disease, and a higher susceptibility to sexually transmitted infections, among others. We believe that companies that advertise these products as beneficial for vaginal health and hygiene can be perceived as not just misinforming women but also profiting from products that are harmful.     

Recency and suffix effects with immediate recall of olfactory stimuli

In contrast to our understanding of the immediate recall of auditory and visual material, little is known about the corresponding characteristics of short-term olfactory memory. The current study investigated the pattern of immediate serial recall and the associated suffix effect using olfactory stimuli. Subjects were trained initially to identify and name correctly nine different odours. Experiment 1 established an immediate correct recall span of approximately six items. In Experiment 2 participants recalled serially span equivalent lists which were followed by a visual, auditory, or olfactory suffix. Primacy was evident in the recall curves for all three suffix conditions. Recency, in contrast, was evident in the auditory and visual suffix conditions only; there was a strong suffix effect in the olfactory suffix condition. Experiment 3 replicated this pattern of effects using seven-item lists, and demonstrated that the magnitude of the recency and suffix effects obtained in the olfactory modality can equate to that obtained in the auditory modality. It is concluded that the pattern of recency and suffix effects in the olfactory modality is reliable, and poses difficulties for those theories that rely on the presence of a primary linguistic code, sound, or changing state as determinants of these effects in serial recall.     

Gender,sexual orientation,and disordered eating

Abstract

While most patients with bulimia nervosa are heterosexual women, a significant number of men with bulimia nervosa are gay males, suggesting that gay men, more than heterosexual men, may be at risk for developing eating disorders. This study compared the food-related attitudes and behaviors of heterosexual men and women in contrast with those of lesbians and gay men, attempting to find whether one's sexual orientation may contribute to differential risk. Two thousand employees were randomly selected from a large health care corporation, of whom 805 returned a completed questionnaire including Stunkard and Messick's (1985) Dietary Restraint and Disinhibition Scales. A stratified random sample was drawn to include demographically comparable groups of 25 lesbians, 50 gay men, 75 heterosexual women, and 75 heterosexual men. Women were less satisfied with their appearance at their present weight and expressed more restraint and more negative feelings after bingeing than did men. Heterosexual women were most dissatisfied with their weight, although heterosexual men were more objectively overweight. Gay men and heterosexual women were similar in disordered eating patterns and disinhibition, contrasting with lesbians and heterosexual men.     

Crowd Effects in Unfamiliar Face Matching

Psychological research shows that humans can not reliably match unfamiliar faces. This presents a practical problem, because identity verification processes in a variety of occupational settings depend on people to perform these tasks reliably. In this context, it is surprising that very few studies have attempted to improve human performance. Here, we investigate whether distributing face matching tasks across groups of individuals might help to solve this problem. Across four studies, we measure the accuracy of the ‘crowd’ on a standard test of face matching ability and find that aggregating individual responses produces substantial gains in matching accuracy. We discuss the practical implications of this result and also suggest ways in which this approach might be used to improve our understanding of face perception more generally.

Memory and Executive Functions in Pediatric Chronic Kidney Disease

This study examined the memory and executive functioning of children and adolescents with chronic kidney disease (CKD). The sample included 20 children and adolescents with CKD ranging in age from 7.50 to 19.04 years (M = 13.41, SD = 3.20). Intellectual function for the group was within the low average to average range (M = 89.32, SD = 14.80). Of the participants with CKD, 12 were receiving maintenance dialysis therapy at the time of testing and 8 were managed with conservative therapy. Healthy controls were used as a comparison group (n = 18). This group ranged in age from 7.47 to 18.37 years (M = 12.93, SD = 2.90). Intellectual function was within the average range (M = 112.18, SD = 13.14). All subjects received a comprehensive battery of memory and executive function tasks as part of a larger neuropsychological evaluation. Preliminary examinations of the data revealed a significant difference between the groups in IQ, with the typical group being significantly higher than the CKD group. A multivariate analysis controlling for chronological age revealed significant group differences, with specific differences being noted in all of the memory functions, and the Initiation and Sustaining executive function domains. In all instances the CKD group performed lower than the typical group. The CKD group was particularly deficient in their initiation behaviors within the executive function domain. The groups did not differ on Set-Shifting or Inhibition. These findings remained present even when IQ and chronological age were controlled in the analyses, suggesting the possibility of specific encroachment of renal disease on memory and executive functions beyond the generalized effects of lower IQ. This study represents one of the most extensive examinations of memory and executive functions that has been conducted to date on children and adolescents with CKD. While pervasive dysfunction was not apparent in the children with CKD, they clearly appeared to be at risk for lower IQ as well as inefficiencies in key neurocognitive domains.     

Analyzing Components of Reading On Performance Assessments: An Expanded Simple View

This research examined the validity of the theoretical model of reading outlined by the Simple View of Reading when measuring reading ability with a performance-based reading test. Participants were 95 fourth-grade, students randomly sampled from four schools in an urban district. The test we studied employed a mixture of traditional (multiple-choice) and performance assessment approaches (constructed-response items that required written responses). Our findings indicated that writing ability emerged as an important source of individual differences in explaining overall reading ability, even when we deconstructed the test into a multiple-choice-only score.     

The Moderating Effect of Anxiety on Development in Atypically Developing Toddlers

In typically developing children, researchers have found that anxiety disorders are associated with poorer intellectual abilities (Davis et al. Journal of Psychopathology and Behavioral Assessment 30:43–51, 2008). The aim of the current study was to examine the impact anxiety symptoms had on the developmental quotients of toddlers. A total of 170 toddlers ranging in age from 17 to 37 months were selected for inclusion in this study, all of whom were at risk for or had a developmental delay. Two factors indicative of behavioral symptoms of anxiety from the Baby and Infant Screen for Children with aUtIsm Traits-Part2 were utilized as the independent variables and the total developmental quotient from the Battelle Developmental Inventory, 2nd Edition was utilized for the dependent variable. Examination of results revealed that atypically developing toddlers with symptoms of anxiety had significantly lower developmental quotients when compared to toddlers without any anxiety symptoms. A discussion of the implications and limitations of this study are included.     

More Research Questions: Rebuttal to Bornstein, Langer, and Stickney

Stickney (2010), Bornstein (2010), and Langer (2010) expand the research recommendations for experimental writing research that Range and Jenkins (2010) generated from gender schema, gender role, and socialization theory. Stickney derives research questions from communication and emotion theory. Bornstein and Langer focus on assessment in this paradigm. Bornstein’s multimodal assessment strategy might improve understanding of apparently inconsistent findings, indicate unstudied processes of interest, and show how changing instructions might maximize writing benefits. Langer’s recommendations to examine gender differences in pre/post/and follow-up emotional outcomes, and in subjective, expressive, and physiological indicators of emotion, identify potential new outcome measures in this research. All three commentaries show promise of advancing our understanding of how writing about trauma might help women and men.
