The role of depression symptoms in dialysis withdrawal.   总被引:3,自引:0,他引:3  
Among end-stage renal disease (ESRD) patients on hemodialysis, death from withdrawal from life-sustaining dialysis is increasingly common. The present study's objective was to examine depression as a potential risk factor for hemodialysis withdrawal. Two hundred forty ESRD hemodialysis (133 male and 107 female) patients were followed for an average of 4 years after depression symptom assessment. Of these, 18% withdrew from dialysis. Using multivariate survival analysis and after controlling for the effects of age (p < .001) and clinical variables, the authors found that level of depression symptoms was a unique and significant predictive risk factor for the subsequent decision to withdraw from dialysis (p < .05). The potential impact that depression may have on the decision to withdraw from hemodialysis should be considered by health care providers, patient families, and patients.  相似文献

The increasing occurrence of suicide bombing attacks highlights a question that has received little direct empirical attention in social psychology. Why are people willing to sacrifice their lives to advance an ideological agenda? The current research suggests that willingness to self‐sacrifice reflects efforts to manage death awareness by investing in a symbolic identity that provides some form of immortality. If willingness to self‐sacrifice is a response to death awareness then increasing the salience of death thoughts should lead to an increase in willingness to self‐sacrifice for a death‐transcending symbolic identity (e.g. one's nation). Further, if self‐sacrifice after mortality salience (MS) is a striving for symbolic immortality then having participants imagine an alternative way to transcend death should moderate this effect. Support for these hypotheses was found as MS increased willingness of British participants to self‐sacrifice for England, but only when an alternative route to symbolic immortality was not provided. Implications are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

This study integrates research linking academic performance with individual differences and class attendance. Whereas individual differences (ability, traits) are not controllable by students, students can control their attendance, study and work. Thus we sought to determine the extent to which “control” and “no control” variables predict academic performance. With N = 338, measures of verbal ability, the five-factor model, GPA, academic goals, and study behavior were used to predict exams, attendance, and independent projects completed. Uncontrollable factors accounted for 37% of the variance in exam scores; controllable factors accounted for an additional 6–10%. We also found an interaction such that, relative to low-ability peers, high-ability students’ attendance most enhanced their exam performance. Attendance was best accounted for by GPA, study and work. Projects were best predicted by low verbal ability and by personality traits.  相似文献

It has been suggested that individuals with synaesthesia may show heightened creativity as a result of being able to form meaningful associations between disparate stimuli (e.g. colour, sound). In this study, a large sample (N=82) of people with various kinds of synaesthesia were given two psychometric tests of creativity (Remote Associates Test, Alternate Uses Test) and were also asked about the amount of time engaged in creative arts (visual art, music). There was a significant tendency for synaesthetes to spend more time engaged in creative arts and this was, at least in part, dependent upon the type of synaesthesia experienced. For example, synaesthetes experiencing vision from music were far more likely to play an instrument than their other synaesthetic counterparts. There was no relationship between this tendency and the psychometric measures of creativity, but synaesthetes did outperform controls on one of the two psychometric measures (Remote Associates). We conclude that the tendency for synaesthetes to be more engaged in art is likely to have a different mechanism to psychometric measures of creativity, and that there is no direct link between them. Although synaesthetes may well perform better on some measures of creativity, we suggest that synaesthetes have better bottom‐up access to certain associations, but are not necessarily better able to use them flexibly (in divergent thinking).  相似文献

In the sociological tradition, status characteristics and patterns of interpersonal relations within a social network are considered important in explaining organizational behaviour (e.g. influence, cooperation). In the social identity tradition, perceptions of shared psychological group membership and group prototypicality are considered important in explaining many of the same organizational behaviours. The present paper explores core variables within each of these perspectives as predictors of advice seeking among supervisors in a manufacturing facility. Dyadic measures of group assignment are found to better predict advice seeking than measures taken at the individual level. Identification with work groups predicted advice seeking from those perceived to be in the same group, and also from structural equivalents. Implications for theory and further research are discussed.  相似文献

Fifty mothers and 48 fathers of soon-to-be-independent children were interviewed to determine how agentic and communal generative themes would be reflected in parenting, occupation, volunteer work, and leisure activities. Mothers reported more communal themes (F5, 83 = 2.32, p <.05). Correlations between generativity and well-being resulted in a negative relationship for mothers in parenting communal generative acts (r = –.41, p = .007) and total generative acts (r = –.3, p = .05) as assessed by the interview. Negative correlations also emerged between mothers' well-being and communal generative acts from the Generative Behavior Checklist, (r = –.33, p = .02).  相似文献

Students, faculty, and researchers have become increasingly comfortable with the Internet, and many of them are interestedin using the Web to collectdata. Few published studies have investigated the differences between Web-based data and data collected with more traditional methods. In order to investigate these potential differences, two important factors were crossed in this study: whether the data were collected on line or not and whether the data were collected in a group setting at a fixed time or individually at a time of the respondent’s choosing. The Visions of Morality scale (Shelton & McAdams, 1990) was used, and the participants were assigned to one of four conditions: in-class Web survey, in-class paper-and-pencil survey; take-home Web survey, and take-home paper-and-pencil survey. No significant differences in scores were found for any condition; however, response rates were affected by the type of survey administered, with the take-home Web-based instrument having the lowest response rate. Therefore, researchers need to be aware that different modes of administration may affect subject attrition and may, therefore, confound investigations of other independent variables.  相似文献

Sense of Coherence (SOC) is conceptualized as a disposition to experience life as meaningful and manageable. Research suggests a protective effect of SOC on psychological health in stressful circumstances. This study assessed the capacity of SOC to buffer the effect of illness symptoms on psychological distress among patients with fibromyalgia. Self-reported changes in SOC after participation in a Mindfulness-Based Stress Reduction (MBSR) program were also examined. Ninety-one women with fibromyalgia provided baseline data pertaining to illness symptoms, perceived stress, and depression prior to participation in a randomized trial of MBSR. SOC and fibromyalgia symptoms were independently related to perceived stress and depression at baseline. SOC was not a statistically significant moderator of symptom effects on psychological distress. In comparison with wait-listed controls, program participants reported a significant increase in SOC after MBSR participation. These results provide the first demonstration from a randomized trial that SOC may be enhanced via intervention.  相似文献

Implantable cardioverter-defibrillators (ICDs) are the treatment of choice for patients at risk for potentially life threatening arrhythmias. The associated stress of living with an implanted device and receiving ICD shock therapy has been noted to exert a psychological toll on the individual patient and family. Anxious and depressive symptomatology is frequently reported by these patients, thus creating a demand for tailored psychological interventions for this population. The current case report describes the components, delivery, and effectiveness of a targeted treatment approach for anxiety and depression in an individual with an ICD. Test results and interview data revealed significant improvements in multiple domains of cognitive, emotional, and behavioral functioning. Improvements in marital relations were also achieved. These treatment effects were maintained at follow-up and in the context of acute, medical stressors. Future clinical and research directions are also discussed.  相似文献

The identical elements (IE) theory of fact representation (Rickard, 2005) proposes that memorized facts that are composed of identical elements (e.g., 6 × 8 = 48 and 8 × 6 = 48) share a common representation in memory, whereas facts with nonidentical elements (e.g., 6 × 8 = 48 and 48 ÷ 8 = 6) are represented separately in memory. The IE model has been successfully applied to the transfer of practice in simple multiplication and division, in transition from procedure-based to retrieval-based performance, and in cued episodic recall. In the present article, we examined the effects of practicing simple addition problems (e.g., 3 + 6 = 9) on the performance of corresponding subtraction problems (9 − 6 = 3), and vice versa. According to IE theory, there should be no transfer of retrieval savings between addition and subtraction facts if performance is based on discrete IE fact representations. Cross-operation response time savings were observed, however, for both small, well-memorized problems (e.g., practice 3 + 2, test 5 − 2) and larger problems (6 + 8, 14 − 6), and they were statistically robust when trials that were self-reported as direct retrieval were analyzed. The transfer of retrieval practice savings between facts with nonidentical elements challenges IE theory as a comprehensive model of transfer in memory retrieval.  相似文献
