Abstract

This study examines the effects of personal resources of both heart patients and their close social partners on patients' coping and quality of life. Generalized personal resources (self-efficacy beliefs, dispositional optimism, self-regulation competence) and outcomes were assessed by questionnaire 1–3 days before surgery (n = 122) and again six months later (n= 50). Outcome variables were coping styles, social resources (social support and social integration), emotional states, and further measures of quality of life. Patients' personal resources were dominant in the prediction of most of the outcomes. Partners' resources were uniquely related to social support, social integration, and quality of life as perceived by the patients. Further, partners' personality resources predicted changes in patients' loneliness and energy levels during the six-month interval.  相似文献

Abstract

The role of coping and social support in the quality of life for Parkinson's Disease (PD) patients is not well understood. Most studies are cross-sectional and concentrate on depression as an outcome measure. The aim of the present study was to explore the role of coping and social support in quality of life for patients with PD. Self-report measures were completed by 105 sufferers of PD; 75 completed the same questionnaire a year later. Patients had the most problems with social function, followed by problems with mobility control and psychological autonomy and communication. After controlling for age, gender and illness duration, the number of PD symptoms predicted mobility control, social functioning and psychological function. Passive coping explained additional variance in most functional domains with more passive coping being related to increased problems. The quality of life was highly stable over the course of the year. Active coping was related to superior psychological functioning one year later. In fact, this was the only coping and social support variable related to functioning after one year, when controlling for previous functions. The results are discussed in terms of the importance of symptom management in PD.  相似文献

This study investigated the impact of personal resilience (a composite measure of optimism, perceived control and self-esteem) on outcome measures in 67 Chinese coronary heart disease patients in response to an 8-week rehabilitation programme. The effect of personal resilience on posttraumatic growth attributed to the onset of heart disease was also examined. Results indicated that coronary heart disease patients high in personal resilience achieved better outcomes than those low in personal resilience, as indicated by higher physical and mental summary measures in SF-36, lower cholesterol levels and better performance on the 6?min walk test. Moreover, personal resilience was demonstrated to be a significant predictor of the level of posttraumatic growth although the rehabilitation programme exerted a weak mediating effect on the link between personal resilience and posttraumatic growth. Findings were discussed in relation to clinical implications of the construct of personal resilience and the intervention programme.  相似文献

Previous studies offer contradictory evidence regarding the effects of cortisol changes on health outcomes for surgical heart patients. Increased cortisol and inflammation have been related to psychological stress while separate studies have found an inverse relation between cortisol and inflammation. Psychological preparations for surgery can reduce stress and improve outcomes and may interact with cortisol changes. Following from these relationships, we hypothesised that a preparation for surgery will interact with changes in cortisol to affect outcomes. Measures were the SF 36 General Health and Activities, medical visits and satisfaction. Eighty-five patients were randomly assigned to standard care plus a psychological preparation or standard care alone using a single-blind methodology. Data on psychological and biological functioning were collected at admission, 1 day prior and 5 days post-surgery, and 12-months after hospital discharge. General health and activities, and medical visits were related to the interaction of cortisol change and psychological preparation in support of the hypothesis. Patients were more satisfied in the preparation group than controls. Based on these findings, some outcomes from psychological preparations may be affected by changes in levels of cortisol. These results caution against a one-size-fits-all approach to psychological preparations.  相似文献

Objective: Acute changes in social belonging are important triggers for alterations in health and well-being, yet research has emphasised the negative effects of ‘exclusion’ at the expense of evaluating the potentially positive effects of ‘inclusion’. This study examined the impact of acute belonging on physiological and psychological outcomes.

Design and main outcome measures: A healthy population (N?=?138) were randomly allocated to ‘included’ or ‘excluded’ conditions. Condition-dependent differences in pre/during-task heart rate and pre/post-task self-reports of negative/positive mood, and social self-esteem, were assessed.

Results: Included participants showed decreased heart rate and negative mood, and increased social self-esteem. No inclusion-related change in positive mood was shown. An increase in heart rate was observed in excluded participants though no changes in negative/positive mood or social self-esteem were shown. Shifts in social self-esteem acted as a mechanism through which inclusion/exclusion impacted upon negative and positive mood alterations. Results remained significant in presence of covariates (sex, global self-esteem, rumination and social anxiety).

Conclusion: Findings suggest that acting to enhance belonging through ‘inclusion’ resulted in adaptive physiological and psychological outcomes. Neutral and potentially protective responses were observed in the immediate aftermath of ‘exclusion’. Self-esteem served as one route through which these effects were transmitted.  相似文献

Objectives: Despite improvements in many domains of functioning, sexual quality of life often remains impaired following coronary artery bypass graft (CABG) surgery. This study examined associations among sexual quality of life, fear of sexual activity and receiving information from providers about sexual activity in CABG patients.

Methods: Participants completed a survey assessing sexual activity, mental health and physical health at baseline (3–5-day post-surgery; n?=?60) and 2-month post-surgery (n?=?42).

Results: Sexual quality of life showed moderate difficulties at baseline and did not improve by follow-up (p values ≥0.09). At follow-up, greater patient fear was associated with lower sexual quality of life in some domains; receiving information was related to lower fear (p values ≤0.03) and greater sexual satisfaction and interest (p values ≤0.04). Suggestive of mediation, there was a significant indirect effect of information on patient fear and of patient fear on sexual interest (p?=?0.05).

Conclusions: Though data were cross-sectional, findings suggest that fears of sexual activity may play a role in lowering CABG patients’ motivation for sexual activity and that receiving information from a medical provider may assist in hastening sexual rehabilitation. Prospective and intervention studies are needed to support findings.  相似文献

Objective: The diagnosis of a life-threatening illness can trigger end-of-life fears. Early studies show that end-of-life fears play an important role in chronic obstructive pulmonary disease (COPD). However, predictors of these fears have not yet been identified. This study investigated the relevance of socio-demographic variables, illness severity, psychological distress and disease-specific anxieties as predictors of end-of-life fears in COPD.

Design: A total of 131 COPD patients participated at two time points. Regression and mediation analyses, as well as cross-lagged panel analyses were conducted.

Main outcome measures: The participants completed questionnaires assessing end-of-life fears (Multidimensional Orientation toward Dying and Death Inventory), psychological distress (Hospital Anxiety and Depression Scale), and disease-specific anxieties (COPD Anxiety Questionnaire). Pulmonary function and a 6-min walk test served as measures of illness severity.

Results: Illness severity was not predictive of end-of-life fears. However, gender and psychological distress explained incremental variance. When disease-specific anxieties were included as additional predictors, psychological distress was no longer significant. Cross-lagged panel analyses mostly supported these results. Moreover, disease-specific anxieties mediated the association between psychological distress and end-of-life fears.

Conclusion: Administration and intensity of end-of-life care (especially concerning end-of-life fears) in COPD patients should be based not only on illness severity, but rather on psychological distress and disease-specific anxieties.  相似文献

Given the effectiveness of putative escape extinction as treatment for feeding problems, it is surprising that little is known about the effects of escape as reinforcement for appropriate eating during treatment. In the current investigation, we examined the effectiveness of escape as reinforcement for mouth clean (a product measure of swallowing), escape as reinforcement for mouth clean plus escape extinction (EE), and EE alone as treatment for the food refusal of 5 children. Results were similar to those of previous studies, in that reinforcement alone did not result in increases in mouth clean or decreases in inappropriate behavior (e.g., Piazza, Patel, Gulotta, Sevin, & Layer, 2003). Increases in mouth clean and decreases in inappropriate behavior occurred when the therapist implemented EE independent of the presence or absence of reinforcement. Results are discussed in terms of the role of negative reinforcement in the etiology and treatment of feeding problems.  相似文献

Abstract

The aim of the present study was to investigate the relationship between resting heart rate variability (HRV) and cognitive functions during threat of shock. A Continuous Performance Task and a Working Memory Task were used to measure cognitive functions. Sixty-five male participants from the Royal Norwegian Navy participated. HRV was measured during baseline, test conditions and recovery. Participants were randomly assigned into non-threat and threat groups. Based on the median split of the high frequency (HF) spectral power, groups were divided into two additional groups. Overall, the high HRV participants showed superior performance on cognitive tasks independent of non-threat or threat conditions. During threat condition the low HRV group showed improved performance. Thus, individuals with high HRV were more stress tolerant and resilient in the face of environmental changes. The results from the study might have implications with regard to performance in operational settings, but also for other fields of psychological research such as individual differences, anxiety and coping.  相似文献

Complications involving the central nervous system are among the most devastating manifestations of sickle cell disease. Although overt stroke occurs in 1 in 10 children with Hemoglobin SS, “silent cerebral infarcts” are even more frequent. Both are associated with significant neuropsychological deficits. The end result of these effects on the CNS often is diminished school performance. The use of transcranial Doppler ultrasonography screening allows the identification of patients at high risk for clinical stroke as well as stroke prevention by chronic transfusion. However, definitive prophylaxis and treatment for most CNS complications of sickle cell disease have yet to be determined.  相似文献
