Public Trust in Genomic Risk Assessment for Type 2 Diabetes Mellitus

Patient trust in personal medical information is critical to increasing adherence to physician recommendations and medications. One of the anticipated benefits of learning of one’s genomic risk for common diseases is the increased adoption of screening, preventive care and lifestyle changes. However, the equivocal results thus far reported of the positive impact of knowledge of genomic risk on behavior change may be due to lack of patients’ trust in the results. As part of a clinical study to compare two methods of communication of genomic risk results for Type 2 diabetes mellitus (T2DM), we assessed patients’ trust and preferred methods of delivery of genomic risk information. A total of 300 participants recruited from the general public in Durham, NC were randomized to receive their genomic risk for T2DM in-person from a genetic counselor or online through the testing company’s web-site. Participants completed a baseline survey and three follow-up surveys after receiving results. Overall, participants reported high levels of trust in the test results. Participants who received their results in-person from the genetic counselor were significantly more likely to trust their results than those who reviewed their results on-line (p?=?0.005). There was not a statistically significant difference in levels of trust among participants with increased genetic risk, as compared to other those with decreased or same as population risk (p?=?0.1154). In the event they undergo genomic risk testing again, 55 % of participants overall indicated they would prefer to receive their results online compared to 28 % that would prefer to receive future results in-person. Of those participants preferring to receive results online, 77 % indicated they would prefer to have the option to speak to someone if they had questions with the online results (compared to accessing results online without the option of professional consultation). This is the first study to assess satisfaction with genomic risk testing by the method of delivery of the test result. The higher rate of trust in results delivered in-person suggests that online access reports may not result in serious consideration of results and lack of adoption of recommended preventive recommendations.     

Aging and the segmentation of narrative film

The perception of event structure in continuous activity is important for everyday comprehension. Although the segmentation of experience into events is a normal concomitant of perceptual processing, previous research has shown age differences in the ability to perceive structure in naturalistic activity, such as a movie of someone washing a car. However, past research has also shown that older adults have a preserved ability to comprehend events in narrative text, which suggests that narrative may improve the event processing of older adults. This study tested whether there are age differences in event segmentation at the intersection of continuous activity and narrative: narrative film. Younger and older adults watched and segmented a narrative film, The Red Balloon, into coarse and fine events. Changes in situational features, such as changes in characters, goals, and objects predicted segmentation. Analyses revealed little age-difference in segmentation behavior. This suggests the possibility that narrative structure supports event understanding for older adults.

Visual similarity effects on masked priming

We investigated the role of the visual similarity of masked primes to targets in a lexical decision experiment. In the primes, some letters in the target (e.g., A in ABANDON) had either visually similar letters (e.g., H), dissimilar letters (D), visually similar digits (4), or dissimilar digits (6) substituted for them. The similarities of the digits and letters to the base letter were equated and verified in a two-alternative forced choice (2AFC) perceptual identification task. Using targets presented in lowercase (e.g., abandon) and primes presented in uppercase, visually similar digit primes (e.g., 484NDON) produced more priming than did visually dissimilar digit primes (676NDON), but little difference was found between the visually similar and dissimilar letter primes (HRHNDON vs. DWDNDON). These results were explained in terms of task-driven competition between the target letter and the visually similar letter.     

Advancing an Understanding of the Anxiety Control Questionnaire for Children (ACQ-C) in Clinically Anxious and Non-Anxious Youth: Psychometric Properties,Incremental Prediction and Developmental Differences

A lack of perceived control over anxiety-related situations is theorized to be characteristic of anxiety disorders in children and adolescents. In the current study we tested several theoretical predictions and developmental variation with the Dutch translation of the Anxiety Control Questionnaire for Children (ACQ-C). The theoretical factor structure of anxiety control was tested using Confirmatory Factor Analysis (CFA) in 548 non-referred children (8–18 years old, M?=?12.5 years; 50.7 % girls). The incremental predictive validity of perceived control for anxiety status was assessed using logistic regression in 141 clinically anxious children (age M?=?12.6 years; 56.7 % girls) and 298 non-referred non-anxious children (age M?=?12.6 years; 52.7 % girls). CFA showed that both a one-factor model and two-factor model (perceived control over internal reactions and external events) fit well. The one-factor model proved invariant across age and gender. Internal consistency was excellent (Cronbach’s α?=?.93). Two-month test-retest reliability was adequate. The ACQ-C was able to incrementally predict diagnostic status, even after controlling for age, gender and self-reported anxiety symptoms. Finally, both younger children and girls reported less perceived control, independent of anxiety level. Findings advance the understanding of the psychometric properties of the ACQ-C, the role of control in childhood anxiety and point to the potential utility of the ACQ-C in both clinical and community samples. The Dutch translation of the ACQ-C demonstrated sound psychometric properties.     

The Choice Architect’s Trilemma

Critics have long dismissed paternalistic choice architecture as conceptually muddled at best and oxymoronic at worst. In this article, I argue that this criticism remains true despite recent replies to the contrary. Further, I suggest that a similar conceptual criticism also applies to non-paternalistic choice architecture. This is due to a three-way tension between the effectiveness, avoidability, and distinctiveness of each nudge. To illustrate this tension, I provide a novel explanation of the mechanics of nudging and a taxonomy of these interventions. I then argue that choice architects who defend the distinctiveness of nudging according to how it guides our behaviour via our unreflective intuitive reasoning encounter a trilemma because the distinctiveness of nudging hinges on interventions being both avoidable and effective. Choice architects cannot achieve this aim without harnessing both our automatic and reflective systems of thought in tandem. However, this diminishes the distinctive character of nudging by bringing it closer to other traditional policy interventions. This establishes the choice architect’s trilemma: a nudge is likely to be either ineffective, effective via some morally unacceptable means, or effective in a manner that is conceptually indistinct from other evidence-based policy interventions.     

Insufficient evidence: mindset intervention in developmental college math

It is generally accepted by educators and social psychologists that non-cognitive factors influence learning. Students who have a fixed view of intelligence believe that abilities are permanent. They view set-backs and the need for effort as evidence of lack of ability. Students with a growth mindset believe that intelligence and abilities are malleable. Intelligence grows with challenge. The objective of this study was to consider if teaching growth mindset to a group of college students in remedial math classes would increase the likelihood of passing the course and remaining in school. Results found a near statistically significant correlation between growth mindset and passing the course but no evidence to support growth mindset and retention. An intervention to teach growth mindset led to statistically small positive results as measured by Pearson’s product-moment correlation and independent sample t tests. Results suggest that combining a variety of interventions with weak academic students is required.
