BACKGROUND: In this clinical study, attachment theory was applied to research in the field of coping with chronic disease. The approach was to integrate concepts of coping within a framework of attachment theory. It was hypothesised that attachment concepts have an influence on coping strategies, and that they may predict the subjective emotional and physical health status during the course of medical treatment. METHOD: One hundred fifty patients were investigated with an adult attachment interview (AAPR coding system) and a coping interview (Bernese Coping Modes). Self-reported coping modes, social support, the subjective health status and quality of life were also assessed by self-report measures at two or more sampling points of measurement. Three subsamples of patients, suffering from (a) breast cancer, (b) chronic leg ulcers and (c) alopecia, were studied in order to include a broad range of subjective impairment caused by a disease. RESULTS: Findings indicate a moderate statistical effect of attachment patterns on coping strategies when controlling the influence of confounding variables. Insecure attachment was related to less flexible coping. Coping strategies also differed between the different types of insecure attachment; however, there were differences depending on the perspective of the coping behaviour (self- vs. observer ratings) as well. From the observer perspective, ambivalently attached individuals showed more negative emotional coping while avoidantly attached individuals showed more diverting strategies. In the self-report, ambivalently attached patients revealed hyperactivating tendencies in their coping behaviour while avoidantly attached individuals revealed deactivating tendencies. CONCLUSION: As a conclusion, two levels of coping should be differentiated. One level strongly corresponds with affect regulation, in particular the regulation of attachment-related emotions and concerns, while the other level shows a stronger tendency to outwardly oriented coping. A more secure attachment might be considered to be an important inner resource in the emotional adaptation to chronic diseases. 相似文献

Objective: A significant proportion of breast cancer patients experiences psychiatric morbidity in the first year after a breast cancer diagnosis and/or beginning of treatment. This study attempted to identify and understand the risk factors for developing such problems. Methods: A consecutive series of 87 patients, aged 40-75 years, was assessed prior to diagnosis of breast cancer and followed-up approximately 8 weeks after beginning of cancer treatment and again 9 months after first follow-up. Assessments included measures of psychiatric morbidity using the General Health Questionnaire (GHQ-12), coping style using the Mental Adjustment to Cancer (MAC) Scale, symptom attribution, beliefs about breast cancer, social support, socio-demographic and clinical variables. Results: A total of 85.1% of patients completed both follow-ups. Pre-diagnostically, 32.2% of breast cancer patients scored as a GHQ-12 ‘case.’ GHQ scores fell significantly between pre-diagnostic and both post-diagnostic assessments, especially in women who had thought they had cancer. Predictors of psychological morbidity at first follow-up included pre-diagnostic GHQ-12 score, lack of social support and feelings of ‘personal responsibility/avoidance.’ GHQ-12 ‘caseness’ at second follow-up was predicted by lack of social support alone. Conclusions: Overall, psychiatric morbidity is higher prior to, than following, a definitive diagnosis of breast cancer. Early reactions of this kind are predictive of post-treatment adjustment. However, only the presence of social support in this study seems to be associated with successful adjustment in the first year following a breast cancer diagnosis. Women at increased risk of psychological morbidity after a breast cancer diagnosis may be thus identifiable and targeted therapeutically. 相似文献

The question addressed in this paper is whether different coping styles mediate the relationship between psychopathology and related distress and the quality of life (QOL) among patients with schizophrenia. In a cross-sectional design, 161 schizophrenia inpatients were comprehensively evaluated with standardized measures of QOL, psychopathology, psychological distress and coping styles. Correlations and regression analyses were performed to examine the relationship among parameters and to estimate the mediating effect of coping styles on QOL in the framework of a distress/protection model. Life quality correlated positively with task- and avoidance-oriented coping styles and slightly negatively with emotion-oriented coping. Emotion-oriented coping mediated the relationship between the severity of activation, anxiety/depression symptoms, and QOL, while avoidance-oriented (distraction) coping was mediated between QOL and paranoid symptoms. Coping styles accounted for 25% of the variance in subjective QOL scores compared with 15% for psychological distress, and only 3% for clinical variables. The ability to cope with symptoms and associated distress substantially contributes to QOL appraisal in schizophrenia. Thus, different coping strategies may reduce the negative influence of specific symptoms and related distress on the subjective QOL of schizophrenia patients. 相似文献

BACKGROUND: Videotapes presenting information concerning children's anaesthesia are often based on what the makers of the videotape believe the parents want to know rather than what parents actually want to know. They frequently do not take into account the parent's coping style. Two common parental coping styles are information-seeking (monitoring) and information-avoiding (blunting). METHODS: We wished to take parent needs into account when making our local videotape and accordingly constructed a questionnaire designed to elicit these needs. RESULTS: Of the parents questioned, 55% wanted more extensive preoperative information and 41% of parents wanted a videotape as part of this preparation. Information about premedication, induction of anaesthesia, side-effects of anaesthesia and postoperative pain management were sought by more than 70% of parents. Parents had concerns about induction of anaesthesia, emergence from anaesthesia and postoperative pain and nausea. When asked a question concerning preference about being present at the induction of anaesthesia, 90% of parents wanted to be present at the induction and 75% of parents thought that their child should receive a premedicant. The number of parents requesting to be present at the induction decreased to 72% after an explanation about the purpose and effects of premedication. There was no correlation between the coping style of the parent and the responses given to the questions. There was no correlation between the level of education and the coping style of the parent. CONCLUSIONS: The use of a questionnaire of parental attitudes towards information and anaesthesia provided a useful tool in the production of a video as part of our preoperative preparation. Our videotape has proved a success with staff and parents and children and enhances the quality of our service. Its popularity stems from the fact that it addresses what the parents want to know and also conveys what the staff of this hospital would like the parents to know. 相似文献

Objective
Childhood traumatic experiences,
rearing styles, familial mental disorders and birth
risk factors have been associated with the development
of social anxiety disorder.
Method
Patients with social
anxiety disorder (n = 50) and healthy controls (n = 120)
were investigated using a retrospective interview with
203 questions.
Results
The frequency of reports of traumatic
childhood experiences was significantly higher in
patients than in controls, including separation from parents,
parents marital discord, sexual abuse, familial violence,
childhood illness, and other factors. On a 0–10
point severe trauma scale patients had significantly
higher mean scores (2.0; SD 1.28) than control subjects
(0.82; SD 1.1; p < 0.0001).Only 6 (12 %) of the social phobic
patients, but 63 (52.5%) of the controls did not report
any severe traumatic events at all (2= 24.0; p <
0.0001). Compared to controls, patients described their
parents rearing styles as significantly more unfavourable.
Patients reported higher rates of psychiatric
disorders in their families in general, in particular anxiety
disorders, depression, and suicidality. Birth risk factors
did not differ between patients and controls. In a logistic
regression model, the highest contribution was
noted for familial anxiety disorders. Separation from
parents also had a significant, but smaller influence.
There was only a trend towards a significant contribution
of childhood sexual abuse. Violence in the family,
parental rearing styles and birth risk factors did not
contribute significantly.
Conclusions
The present data
suggest that the aetiology of social anxiety disorder is
multifactorial and that familial mental disorders and
separation experiences are the most important contributing
factors. 相似文献

Examining students learning styles can yield information useful to the design of learning activities, courses, and curricula. A variety of measures have been used to characterize learning styles, but the literature contains little information specific to biomedical engineering (BMEN) students. We, therefore, utilized Felders Index of Learning Styles to investigate the learning style preferences of BMEN students at Tulane University. Tulane BMEN students preferred to receive information visually (preferred by 88% of the student sample) rather than verbally, focus on sensory information (55%) instead of intuitive information, process information actively (66%) instead of reflectively, and understand information globally (59%) rather than sequentially. These preferences varied between cohorts (freshman, sophomore, etc.) and a significantly higher percentage of female students preferred active and sensing learning styles. Compared to other engineering student populations, our sample of Tulane BMEN students contained the highest percentage of students preferring the global learning style. Whether this is a general trend for all BMEN students or a trait specific to Tulane engineers requires further investigation. Regardless, this study confirms the existence of a range of learning styles within biomedical engineering students, and provides motivation for instructors to consider how well their teaching style engages multiple learning styles. © 2002 Biomedical Engineering Society.
