Primary Care Medical Provider Attitudes Regarding Mental Health and Behavioral Medicine in Integrated and Non-integrated Primary Care Practice Settings

Primary care medical providers (PCPs) have become de facto providers of services for the management of both mental and chronic illnesses. Although some reports suggest that PCPs favor having Behavioral Health colleagues provide behavioral health services in primary care, others demonstrate this view is necessarily not universal. We examined attitudes regarding behavioral health services among PCPs in practices that offer such services via onsite behavioral health providers (n = 31) and those that do not (n = 62). We compared referral rates and perceived need for and helpfulness of behavioral health colleagues in treating mental health/behavioral medicine issues. In both samples, perceived need was variable (5?C100%), as were PCPs?? views of their own competence in mental health/behavioral medicine diagnosis and treatment. Interestingly, neither sample rated perceived access to behavioral health providers exceptionally high. Referral rates and views about the helpfulness of behavioral health services, except in relation to depression and anxiety, were lower than expected. These results suggest a need for increased collaboration with and education of PCPs about the roles and skills of behavioral health professionals.     

Recognition memory for social and non-social odors: differential effects of neurotoxic lesions to the hippocampus and perirhinal cortex

The contributions of the hippocampus (HC) and perirhinal cortex (PER) to recognition memory are currently topics of debate in neuroscience. Here we used a rapidly-learned (seconds) spontaneous novel odor recognition paradigm to assess the effects of pre-training N-methyl-D-aspartate lesions to the HC or PER on odor recognition memory. We tested memory for both social and non-social odor stimuli. Social odors were acquired from conspecifics, while non-social odors were household spices. Conspecific odor stimuli are ethologically-relevant and have a high degree of overlapping features compared to non-social household spices. Various retention intervals (5 min, 20 min, 1h, 24h, or 48 h) were used between study and test phases, each with a unique odor pair, to assess changes in novelty preference over time. Consistent with findings in other paradigms, modalities, and species, we found that HC lesions yielded no significant recognition memory deficits. In contrast, PER lesions caused significant deficits for social odor recognition memory at long retention intervals, demonstrating a critical role for PER in long-term memory for social odors. PER lesions had no effect on memory for non-social odors. The results are consistent with a general role for PER in long-term recognition memory for stimuli that have a high degree of overlapping features, which must be distinguished by conjunctive representations.     

Evidence for long-term spatial memory in a parid

Many animals use spatial memory. Although much work has examined the accuracy of spatial memory, few studies have explicitly focused on its longevity. The importance of long-term spatial memory for foraging has been demonstrated in several cases. However, the importance of such long-term memory for all animals is unclear. In this study, we present the first evidence that a parid species (the black-capped chickadee, Poecile atricapillus) can remember the location of a single food item for at least 6 months under an associative-learning spatial memory paradigm with multiple reinforcements. We did not detect a significant difference in memory longevity between two populations of chickadees shown previously to differ in short-term spatial memory and hippocampal morphology, an area of the brain involved in spatial memory. Our study showed that small birds such as parids can maintain spatial memories for long periods, a feat shown previously only in corvids. Moreover, we were able to demonstrate this longevity within the context of only 16 repeated trials. We speculate that this ability may potentially be useful in relocating caches if reinforced by repeated visits. Future studies are necessary to test whether our results were specifically due to multiple reinforcements of the food-containing location and whether parids may have similar memory longevity during food-caching experiences in the wild.     

Factors that affect action possibility judgements: recent experience with the action and the current body state

It has been suggested that action possibility judgements are formed through a covert simulation of the to-be-executed action. We sought to determine whether the motor system (via a common coding mechanism) influences this simulation, by investigating whether action possibility judgements are influenced by experience with the movement task (Experiments 1 and 2) and current body states (Experiment 3). The judgement task in each experiment involved judging whether it was possible for a person's hand to accurately move between two targets at presented speeds. In Experiment 1, participants completed the action judgements before and after executing the movement they were required to judge. Results were that judged movement times after execution were closer to the actual execution time than those prior to execution. The results of Experiment 2 suggest that the effects of execution on judgements were not due to motor activation or perceptual task experience-alternative explanations of the execution-mediated judgement effects. Experiment 3 examined how judged movement times were influenced by participants wearing weights. Results revealed that wearing weights increased judged movement times. These results suggest that the simulation underlying the judgement process is connected to the motor system, and that simulations are dynamically generated, taking into account recent experience and current body state.     

Genetic influences on core self-evaluations,job satisfaction,and work stress: A behavioral genetics mediated model

In this study we investigated the mediated influence of core self-evaluations (CSE) on employee health problems via job satisfaction and work stress, and the degree to which genetic factors explain these mediated relationships. Based on data obtained from a sample of 594 Swedish twins (114 monozygotic twin pairs and 183 dizygotic twin pairs), conventional path analysis results supported the mediated effects of CSE on employee health via job satisfaction and work stress, after controlling for conscientiousness and extraversion. Behavioral genetic analyses showed significant heritability of all four variables. Moreover, we found that the mediated relationships via job satisfaction and work stress are explained by genetic factors, such that the genetic source of job satisfaction and work stress mediates the genetic influence of CSE on health problems. These results highlight the role played by genetic factors in better understanding the relationships between CSE, work attitudes, and health outcomes.     

Comparability of Self‐Reported Conscientiousness Across 21 Countries

In cross‐national studies, mean levels of self‐reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self‐report judgements in relation to culture‐specific standards (often called the reference group effect), thereby undermining the cross‐cultural comparability of the judgements. We employed a simple method called anchoring vignettes in order to test whether people from 21 different countries have varying standards for Conscientiousness, a Big Five personality trait that has repeatedly shown unexpected nation‐level relationships with external criteria. Participants rated their own Conscientiousness and that of 30 hypothetical persons portrayed in short vignettes. The latter type of ratings was expected to reveal individual differences in standards of Conscientiousness. The vignettes were rated relatively similarly in all countries, suggesting no substantial culture‐related differences in standards for Conscientiousness. Controlling for the small differences in standards did not substantially change the rankings of countries on mean self‐ratings or the predictive validities of these rankings for objective criteria. These findings are not consistent with mean self‐rated Conscientiousness scores being influenced by culture‐specific standards. The technique of anchoring vignettes can be used in various types of studies to assess the potentially confounding effects of reference levels. Copyright © 2011 John Wiley & Sons, Ltd.     

Procrastination and Self-Regulatory Failure: An Introduction to the Special Issue

As a preface to the papers in this special issue on the role of procrastination in maladjustment, we provide an overview of the topics covered. To our knowledge, this is the first special issue that focuses specifically on the role of this form of self-regulatory failure in understanding maladjustment. We begin with a discussion of the complex array of motivational, affective, cognitive, and behavioural factors that operate in chronic procrastination. These complexities are illustrated with case studies that highlight the role of negative self-views and associated deficits in self-regulation. Themes explored in the papers include the role of cognitive factors in dysfunctional beliefs and automatic thoughts in procrastination, as well as the role of procrastination and deficits in self-regulation related to stress, psychological distress, and physical illness. Another key theme addressed is the usefulness of REBT and cognitive techniques such as mindfulness training in reducing the tendency to procrastinate.
