No seasonality in cognitive performance among adolescents at a subarctic latitude (69°N)

Seasonal changes in daylight are substantial in subarctic areas and are known to affect circadian sleep rhythms. We examined whether seasonality in cognitive performance also exists and to what extent seasonality in sleep moderates this relationship. In the city of Tromsø (Norway) at 69°N, 182 adolescents (36% male; mean age 16.8 years) participated in a prospective study. The cognitive measures included verbal and visual memory, verbal learning, psychomotor speed, and problem solving, whereas sleep and sleep‐related problems were recorded via weekly sleep diaries and questionnaires. The results indicated no effect of season on any of the cognitive tests. Seasonality in sleep timing, insomnia, and fatigue were confirmed; however, these variables did not modify the null correlation between season and cognition. The lack of seasonality in cognition is a positive finding and serves to undermine myths about the burdens of living in subarctic areas with substantial seasonal changes in daylight.     

On "risk" and reward: investigating state anhedonia in psychometrically defined schizotypy and schizophrenia

Anhedonia, defined as dysfunction in the experience of pleasant emotions, is a hallmark symptom of the schizophrenia spectrum. Of interest, it is well documented that patients with schizophrenia, at least as a group, do not show reductions in their state experience of pleasant stimuli. However, there is emerging evidence to suggest that individuals with schizotypy--defined as the personality organization reflecting the latent vulnerability for schizophrenia--do show these state deficits. This is paradoxical in that schizophrenia reflects a more pathological state in virtually every conceivable domain as compared with schizotypy. The present study examined self-reported affective reactions to neutral-, bad-, and good-valenced stimuli in individuals with psychometrically defined schizotypy and schizophrenia. Two separate control groups were also included, comprising psychometrically defined controls and stable outpatients with affective disorders. With no exceptions, the schizotypy group reported significantly less pleasant affect for each of the three conditions than each of the other groups. Conversely, the schizophrenia group did not statistically differ from the control groups for any of the conditions. Within both the schizotypy and schizophrenia groups, severity of negative symptoms/traits was associated with less pleasant report. We found that individuals with prominent negative symptoms and traits from the schizophrenia and schizotypy groups resembled each other in terms of state anhedonia. The present findings did not appear to reflect comorbid depression or anxiety. Our discussion centers on this apparent paradox in the schizophrenia spectrum--that individuals with schizotypy exhibit state anhedonia, whereas patients with schizophrenia do not.     

Identification of Individuals at Risk for Lynch Syndrome Using Targeted Evaluations and Genetic Testing: National Society of Genetic Counselors and the Collaborative Group of the Americas on Inherited Colorectal Cancer Joint Practice Guideline

Identifying individuals who have Lynch syndrome (LS) involves a complex diagnostic work up that includes taking a detailed family history and a combination of various genetic and immunohistochemical tests. The National Society of Genetic Counselors (NSGC) and the Collaborative Group of the Americas on Inherited Colorectal Cancer (CGA-ICC) have come together to publish this clinical practice testing guideline for the evaluation of LS. The purpose of this practice guideline is to provide guidance and a testing algorithm for LS as well as recommendations on when to offer testing. This guideline does not replace a consultation with a genetics professional. This guideline includes explanations in support of this and a summary of background data. While this guideline is not intended to serve as a review of LS, it includes a discussion of background information on LS, and cites a number of key publications which should be reviewed for a more in-depth understanding of LS. These guidelines are intended for genetic counselors, geneticists, gastroenterologists, surgeons, medical oncologists, obstetricians and gynecologists, nurses and other healthcare providers who evaluate patients for LS.     

Satisfaction strength and intention to purchase a new product

This study examines the role of satisfaction strength on the correspondence between reported satisfaction and intention to purchase a new product. The market testing underlying this study analyzes the market opportunities for a novel prototype. The research was conducted at a central location with 239 randomly selected consumers. Results indicate that (un)certainty, ambivalence, and importance cognitions and feelings significantly moderate the relationship between reported satisfaction and individuals' intention to purchase. For example, the association between consumers' reported satisfaction level and purchasing intention of the new product is weaker as uncertainty increases. Significant moderated‐mediation and mediated‐moderation effects were also found with Structural Equation Modelling. Judgments of ambivalence moderate the satisfaction–purchasing intention relationship through the mediating effect of importance. (Un)certainty fully mediates the moderating effect of importance on the satisfaction–purchasing intention link. The research validates the usefulness of assessing the satisfaction strength concept and illustrates its potential as a better predictor of intentions than satisfaction level alone. The study argues on the nomological validity of the satisfaction construct and reveals that assessment of satisfaction strength should support the management goal of identifying truly satisfied customers.

Are Specific Emotion Regulation Strategies Differentially Associated with Posttraumatic Growth Versus Stress?

Extremely few studies have examined emotion regulation strategies as predictors of posttraumatic growth (PTG). This study aimed to examine several specific emotion regulation strategies, along with meaning making, as predictors of PTG, as opposed to posttraumatic distress. Participants were 107 adult women who had experienced a very stressful or traumatic event within the past 3 years and completed questionnaires measuring emotion regulation, meaning making, distress, and PTG. Emotion suppression positively predicted distress, but not PTG. Meaning making positively predicted PTG and negatively predicted distress. Bootstrapped mediation models showed that emotional processing has a significant indirect effect on PTG and distress through its effect on meaning making. Results indicate that researchers should pay closer attention to emotional processes involved in etiological models of PTG. It might also be helpful to examine specific emotion regulation strategies, as these can point to ways to help people navigate recovery from trauma.     

Affect Is Greater Than,Not Equal to,Condition: Condition and Person Effects in Affective Priming Paradigms

Affective primes may impact ensuing behavior through condition and person effects. However, previous research has not experimentally disentangled these two sources of influence in affective priming paradigms. In the current research, we simultaneously examine the influence of condition factors, in terms of prime valence, and person factors, in terms of affect reactivity and personality. In both studies, undergraduate participants (total N = 174) were primed with either positive or negative affective stimuli (words, Study 1; pictures, Study 2) prior to judging the likability of a neutral target (Arabic characters, Study 1; inkblots, Study 2). Although we did observe between‐condition differences for positive and negative primes, person‐level effects were more consistent predictors of target ratings. Affect reactivity (affect Time 2, controlling Time 1) to the primes predicted evaluative judgments, even in the absence of condition effects. In addition, the personality traits of Neuroticism (Study 1) and behavioral inhibition system sensitivity (Study 2) predicted evaluative judgments of neutral targets following negative affective primes. With effects for condition, affect reactivity, and personality, our results suggest that affective primes influence ensuing behaviors through both informational and affective means. Research using affective priming methodologies should take into account both condition and person‐level effects.     

Mental health among people with psoriasis undergoing patient education in climate therapy

This study investigated the mental health of people with psoriasis undergoing patient education in climate therapy. A prospective design included a baseline assessment and two follow‐ups after a 3‐week patient education program. Participants were 254 adults. Positive mental health was measured by the mental health continuum short form (0–70), and negative mental health by the emotional distress subscale (1–4) of the health education impact questionnaire. Paired‐samples t‐tests were used to evaluate changes in mental health from baseline to follow‐up. Multiple linear regression was used to analyse the ability of socio‐demographic and clinical variables and emotional distress to predict changes in positive mental health. To predict change in negative mental health we repeated the same analysis but with a change in negative mental health as a dependent variable and positive mental health as an independent variable. The results show that positive mental health and health‐related emotional distress improved significantly from before to after the intervention by 7.1 points, p < 0.001 and 0.21 points, p < 0.001) respectively. At the second follow‐up, health‐related emotional distress remained significantly improved compared with baseline levels by 0.11 points, p = 0.004. The longer participants had lived with psoriasis ( β = 146, p = 0.027), and the presence of co‐morbid health problems (β  =  111, p = 0.051) the greater the improvement in the positive mental health immediately after the intervention. No predictors were identified for negative mental health. This study indicates that the promotion of positive mental health needs to be integrated into the climate therapy program, and sustained in their home context.     

Exploring the Valence‐Framing Effect: Negative Framing Enhances Attitude Strength

In his now‐classic research on inoculation theory, McGuire (1964 ) demonstrated that exposing people to an initial weak counterattitudinal message could lead to enhanced resistance to a subsequent stronger counterattitudinal message. More recently, research on the valence‐framing effect ( Bizer & Petty, 2005 ) demonstrated an alternative way to make attitudes more resistant. Simply framing a person's attitude negatively (i.e., in terms of a rejected position such as anti‐Democrat) led to more resistance to an attack on that attitude than did framing the same attitude positively (i.e., in terms of a preferred position such as pro‐Republican). Using an election context, the current research tested whether valence framing influences attitude resistance specifically or attitude strength more generally, providing insight into the effect's mechanism and generalizability. In two experiments, attitude valence was manipulated by framing a position either negatively or positively. Experiment 1 showed that negatively framed attitudes were held with more certainty than were positively framed attitudes. In Experiment 2, conducted among a representative sample of residents of two U.S. states during political campaigns, negatively framed attitudes demonstrated higher levels of attitude certainty and attitude‐consistent behavioral intentions than did attitudes that were framed positively. Furthermore, the effect of valence framing on behavioral intentions was mediated by attitude certainty. Valence framing thus appears to be a relatively low‐effort way to impact multiple features associated with strong attitudes.
