The main aim of the current study is to examine the changes in the components of subjective well-being (SWB) over time in patients with osteoarthritis who have undergone total hip or knee replacement surgery (arthroplasty). We are also interested in determining whether pre-operative ratings of self-reported health (SRH) status, as well as change in health status, can serve as predictors for postoperative levels of SWB. To this end, 50 participants who had been admitted to a hospital for arthroplasty completed the measures twice—first at the clinic one day before the surgery, and then at home approximately 4.5 months after the surgery. Despite the fact that there were substantial improvements in participants’ health and physical functioning after the arthroplasty, there were no changes in their ratings of general SRH, life satisfaction (LS), or negative affect (NA). The only change in SWB scores was in the level of positive affect (PA), which was significantly higher after surgery compared with the pre-operative measurement. LS, NA, and PA scores after arthroplasty were differentially predicted by health ratings, showing that, it is the cognitive-evaluative component of SWB (i.e., LS) that is mostly responsible for the association between general SRH and SWB while affective components (i.e., NA and PA) are primarily related to more specific health indicators. Our findings can assist physicians in their efforts to provide more realistic expectations for their patients undergoing surgery in terms of the physical and psychological outcome. 相似文献

Natural images can be classified so rapidly that it has been suggested that their analysis is based on a first single pass of processing activity through the visuomotor system. We tested this theory in a visuomotor priming task in which speeded pointing responses were performed toward one of two target images containing a prespecified stimulus (e.g., animal vs. nonanimal, ellipse vs. rectangle). Target pictures were preceded by prime pictures of the same or an opposite category, linked to either the same or an opposite pointing response. We found that pointing trajectories were initially controlled by the primes alone, but independently of information in the actual targets. Our data indicate that prime and target signals remained strictly sequential throughout all processing stages, meeting unprecedentedly stringent behavioral criteria for feedforward processing (rapid-chase criteria). Our findings suggest that visuomotor priming effects capture the output of the very first pass of information through the visuomotor system, before output is affected by recurrent information. 相似文献

Obesity and visceral fat accumulation are key features of the metabolic syndrome that represents one of the main health problems in western societies due to its neurovascular and cardiovascular complications. Epidemiological studies have identified chronic stress exposure as an important risk factor for the development of obesity and metabolic syndrome, but also psychiatric diseases, especially affective disorders. However, it is still unclear if chronic stress has merely transient or potentially lasting effects on body composition. Here, we investigated the effects of chronic social stress during the adolescent period on body fat composition in mice one year after the cessation of the stressor. We found that stress exposure during the adolescent period decreases subcutaneous fat content, without change in visceral fat, and consequently increases the visceral fat/subcutaneous fat ratio in adulthood. Further, we demonstrated that treatment with a selective serotonin reuptake inhibitor (paroxetine) during stress exposure prevented later effects on body fat distribution. These results from a recently validated chronic stress paradigm in mice provide evidence that stressful experiences during adolescence can alter body fat distribution in adulthood, thereby possibly contributing to an increased risk for metabolic diseases. Antidepressant treatment disrupted this effect underlining the link between the stress hormone system, metabolic homeostasis and affective disorders. 相似文献

It is a long way to the formal recognition of a so-called non-verbal mode of therapy that was long considered only as an additional intervention in complex forms of treatment. A historical overview of the development of music therapy in German psychosomatic medicine is followed by a detailed report of the diversities of present techniques in music therapy. Outcome research shows music therapy to be a richer and more diversified method than one would suppose. On this basis specific indications for the implementation of music therapy in medical settings are identifiable. 相似文献

The construct meaning of assessment center evaluations is an important unresolved issue in I/O psychology. This study hypothesized that Cognitive Ability and personality traits are primary correlates of evaluators’ overall assessment ratings (OARs). Meta–analysis results based on 65 correlations indicate the following mean construct–level correlations with OARs: .67 for Cognitive Ability, .50 for Extraversion, .35 for Emotional Stability, .25 for Openness, and .17 for Agreeableness; yielding a multiple R of .84. These findings support our hypothesis and cast light on the construct meaning of assessment center evaluations. 相似文献

We examined the relationship between being bullied during childhood and activity of the hypothalamic-pituitary-adrenal (HPA) axis as assessed through repeated measures of salivary cortisol. A non-clinical sample of 154 (74 boys) predominantly Caucasian middle-class 12-year-olds each provided detailed information about their experiences with bullying and six saliva samples were standardized across time and day. Children with a history of child maltreatment, diagnosed psychiatric illness, foster care placement, medication use (psychotropic and oral contraception) and aggression directed toward peers and/or family members were excluded. Using multilevel regression and applying orthogonal polynomial contrasts to model the observed circadian pattern in the data, we found that occasional and frequent verbal peer victimization was associated with hyposecretion of cortisol when controlling for sex, pubertal status, age, depression and anxiety. This relation, however, was moderated by sex. For boys, occasional exposure was associated with higher cortisol levels, whereas for girls exposure was associated with lower cortisol levels. The present study highlights the need to consider the plight of peer-victimized children seriously, as it is associated with alterations to the HPA axis that affect males and females differently, and likely diminishes a person's ability to cope with stress, possibly placing them at risk for psychopathology and ill health. 相似文献

Theoretical models of the antecedents and outcomes of work-home interference (WHI) suggest that work characteristics (e.g., job stressors, working hours) increase the probability that an individual experiences work-home interference. Since work-home interference is considered as a role stressor, these experiences should be detrimental for long-term well-being. In this 2-wave panel study, the authors compared this suggested pathway with competing models that propose reverse causation and reciprocal effects in a sample of 365 employees (N at T2 = 130) from the German workforce using structural equation modeling. In particular, a model with two proposed antecedents (job stressors, working hours) of WHI and two proposed consequences (depression, turnover motivation) was analyzed in alternative configurations. The results support a cyclical model with a job stressors → depression → WHI → job stressors pathway. Furthermore, working hours affected WHI, and turnover motivation emerged as an outcome of WHI. 相似文献
