Objective: Depressive symptoms are highly prevalent in heart failure (HF) patients, however the underlying etiology of depression in HF patients remains yet unclear. Hence, the goal is to examine the relative importance of inflammation, disease severity and personality as predictors of depression in HF patients. Design: Depressive symptoms (Hospital Anxiety and Depression Scale, depression subscale) were assessed at baseline and one-year follow-up in 268 HF patients (75.6% men; mean age?=?66.7?±?8.7). Markers of inflammation (TNFα, sTNFr1, sTNFr2, IL-6 and IL-10), disease severity (e.g. New York Heart Association (NYHA) classification) and personality (Type D personality, loneliness) were assessed at baseline. Results: At baseline, NYHA class, body mass index, educational level, Type D personality and loneliness were significantly associated with depression. Higher NYHA class (B?=?2.25; SE?=?.83), higher educational level (B?=?1.41; SE?=?.48), Type D personality (B?=?2.56; SE?=?.60) and loneliness (B?=?.19; SE?=?.05) were also independently associated with higher depression levels at one-year follow-up (all p-values?<?.005). Inflammation, brain natriuretic peptide and left ventricular ejection fraction were not related to depression over time. Conclusions: Personality factors, but not inflammation, were independent concomitants of depressive symptoms in patients with HF. Gaining more insight into the etiology of depression in HF patients is important in order to identify potential targets for novel interventions.  相似文献

According to the probability-matching account of source guessing (Spaniol & Bayen, Journal of Experimental Psychology: Learning, Memory, and Cognition 28:631–651, 2002), when people do not remember the source of an item in a source-monitoring task, they match the source-guessing probabilities to the perceived contingencies between sources and item types. In a source-monitoring experiment, half of the items presented by each of two sources were consistent with schematic expectations about this source, whereas the other half of the items were consistent with schematic expectations about the other source. Participants’ source schemas were activated either at the time of encoding or just before the source-monitoring test. After test, the participants judged the contingency of the item type and source. Individual parameter estimates of source guessing were obtained via beta-multinomial processing tree modeling (beta-MPT; Smith & Batchelder, Journal of Mathematical Psychology 54:167–183, 2010). We found a significant correlation between the perceived contingency and source guessing, as well as a correlation between the deviation of the guessing bias from the true contingency and source memory when participants did not receive the schema information until retrieval. These findings support the probability-matching account.  相似文献

This article takes a critical look at the recent history of the concept of sex addiction, an archetypal modern sexual invention. Sex addiction began as a 1980s product of late twentieth-century cultural anxieties and has remained responsive to those tensions, including its most recent iteration, “hypersexual disorder.” Its success as a concept lay with its medicalization, both as a self-help movement in terms of self-diagnosis, and as a rapidly growing industry of therapists on hand to deal with the new disease. The media has always played a role in its history, first with TV, the tabloids, and the case histories of claimed celebrity victims all helping to popularize the concept, and then with the impact of the internet. Though it is essentially mythical, creating a problem that need not exist, sex addiction has to be taken seriously as a phenomenon. Rarely has a socio-psychological discourse taken such a hold on the public imagination—and proven an influential concept in academic circles too. We argue that this strange, short history of social opportunism, diagnostic amorphism, therapeutic self-interest, and popular cultural endorsement is marked by an essential social conservatism—sex addiction has become a convenient term to describe disapproved sex. Sex addiction is a label without explanatory force.  相似文献

Being a teacher is known to be a particularly stressful occupation and as a consequence many teachers suffer from reduced well-being. Thus, it is important to know as soon as possible which individuals are likely to experience reduced well-being in their employment. Therefore, this study investigated whether it is possible to infer teachers’ future well-being from minimal nonverbal information, i.e., thin slices of behavior. Between 2003 and 2006, 50 teachers were filmed while holding a lesson. Naïve observers were shown 60-s clips of these teachers and were asked to predict the teachers’ satisfaction with job, life, and health in 5–8 years. Five to eight years later, the teachers’ satisfaction with job, life, and health was assessed. It was shown that judges highly agree in their predictions. Additionally, these predictions were shown to be accurate for life and job satisfaction. Thus, it is possible to predict a teacher’s well-being on the basis of thin slices of the nonverbal behavior they show while performing their job. These thin slices might therefore allow for a risk assessment in the context of teacher education and such approaches might contribute to teacher professionalism.  相似文献

Abstract

Two studies, one retrospective and the other prospective, investigated the relation of cognitive strategies (association, dissociation) with injury, motivation, and performance variables among marathon runners. Association was found to predict injury in runners at 4 month follow-up. It appears that association is favored by runners who are more competitive, participate in numerous races, and are heavily invested in running. Contrary to early theorizing, findings demonstrated that dissociation was not related to injury but was related to motivation and performance variables suggesting that dissociating runners tend to run slower, be less competitive, and be less invested in running. It is proposed that motivational and physiological factors account for the use of cognitive strategies among marathon runners.  相似文献

Type D personality, a synergy between negative affectivity and social inhibition, has established itself as a serious risk factor for morbidity and mortality in patients suffering from cardiovascular disease. In this review, we summarize studies on the validity of the assessment methods of Type D, emphasizing its role as an independent vulnerability factor in the progression of cardiovascular disease. We further present evidence on the physiological characteristics that accompany the 2 psychological traits negative affectivity and social inhibition and may mediate the relation between personality and prognosis in heart disease. Further research needs to determine the mechanisms by which Type D affects the course and outcome of cardiovascular disease as well as how Type D patients may benefit from psychosocial intervention.  相似文献

In 2 experiments, the effects of mental stress on limb stiffness were investigated. The relative contribution to arm stiffness of individual muscle activity, co-contraction, muscle reflexes, and postural adjustments were examined. In each experiment, participants (N = 24, Experiment 1; N = 16, Experiment 2) held their supinated hand under a tray that they were required to return to horizontal after it had been suddenly released. Electromyographic activity in the biceps and triceps muscles was recorded, as were elbow and wrist angles and tray displacement. In Experiment 1, mental arithmetic stress was shown to lead to decreased tray displacement (i.e., increased resistance) compared with displacements under the control, unstressed condition, as well as to increased elbow flexion before tray release. In Experiment 2, the increased resistance to perturbation caused by mental stress was found to be independent of initial elbow angle, but to vary as a function of the amount of upward force exerted before tray release. The authors conclude that stress-induced increases in limb stiffness result from changes in the initial position of the elbow, specified by its angle, together with the initial force exerted by participants to counteract the mechanical perturbations.  相似文献

We surveyed 113 college students regarding their views of certain occupational stereotypes. Our results indicated that in this population gender was related to the subjects' views of occupations as either male, female, or neutral, and that the father's primary occupation significantly affected the subjects' views of only one occupation—clinical sociologist. The mother's occupation seemed to have no effect.  相似文献

In this article I explore if and how very young children can be the educators of their early childhood educators. I describe and discuss a story constructed form a fieldwork done in one early childhood setting in Norway. The story is read with Levinas and his concepts Said and Saying. Further I discuss if and how this might be understood as education arguing that the children`s expressions are offering new beginning and change in the pedagogical thinking and praxis within the early childhood setting.  相似文献

Based on self-determination theory (SDT), this study investigated, whether the three central SDT variables (perceived autonomy support, autonomous motivation and self-care competence), were associated with engagement in physical activity (PA) among patients with type 2 diabetes when the effect of a wide variety of other important life-context factors (perceived health, medication, duration of diabetes, mental health, stress and social support) was controlled for. Patients from five municipalities in Finland with registry-based entitlement to a special reimbursement for medicines used in the treatment of type 2 diabetes (n = 2866, mean age 63 years, 56% men) participated in this mail survey in 2011. Of all measured explanatory factors, autonomous motivation was most strongly associated with engagement in PA. Autonomous motivation mediated the effect of perceived autonomy support on patients’ PA. Thus, perceived autonomy support (from one’s physician) was associated with the patient’s PA through autonomous motivation. This result is in line with SDT. Interventions for improved diabetes care should concentrate on supporting patients’ autonomous motivation for PA. Internalizing the importance of good self-care seems to give sufficient energy to maintain a physically active lifestyle.  相似文献
