Development and evaluation of a presurgical preparation program   总被引:2,自引:1,他引:1  
Three presurgical preparation programs were developed and evaluated in an Australian hospital utilizing an additive component design. The component basic to all three preparation programs was modeling. This technique was compared with the additional components of teaching child coping skills and parent coping skills via videotape. Subjects were 28 children between the ages of 4 and 13 years who were scheduled for elective surgery. Anxiety of both the children and parents was assessed by self-report and behavior observation. Results indicated that there was no further anxiety reduction by the addition of child and parent coping skills. Results are discussed in terms of the viability of teaching coping skills via videotape particularly to parents. Methodological difficulties associated with research in this area are examined.  相似文献

李泽平 《中国医院》2002,6(12):10-12
21世纪的医院是文化的医院,21世纪医院的竞争是文化的竞争,谁能构建出具有特色的医院文化,谁就能赢得竞争主动权。构建特色医院文化,核心是形成共同的理想和精神支柱;关键是打造“学习型”医院组织;根本是树立以人为本、诚信求实的服务理念;目标是树立良好的医院形象;基础是加快医院信息化建设。  相似文献

This study investigates the efficacy of an intensive, integrated approach to stress reduction and coping enhancement directed towards an educated, upper level management population. Ninety‐five US governmental senior managers participated in a 35‐h stress management retreat held over a 3.5‐day period. The retreat combined didactic and experiential activities that were designed to increase participants' knowledge of stress liabilities and coping skills. Participants were encouraged to make positive lifestyle changes and to create specific action plans for the year following the workshop. Evaluations of participant satisfaction were completed at the close of the workshop. Eighty‐three participants completed baseline and follow‐up Stress and Coping Inventory (SCI) assessments in order to identify durable changes in these measures. Across 10 months, participants showed significant improvements in their overall Global Balance scores, psychological symptoms, depression symptoms, and all major coping scales, including Health Habits, Social Support, Responses to Stress and Life Satisfactions. Therefore, an intensive, multifaceted approach to stress intervention is a viable option for encouraging sustained behavioural change. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

目的 探讨强迫症患者的防御机制、父母教养方式及其个性特征。方法 采用防御方式问卷 (DSQ)、父母养育方式评价量表 (EMBU)及艾森克个性问卷 (EPQ)对 36例强迫症患者进行了问卷调查 ,并与 36例正常受试者加以比较。结果 ①强迫症组中间型和不成熟防御机制因子分均明显高于正常对照组 (P <0 0 1) ,而成熟防御机制因子分则明显低于正常对照组 (P <0 0 5 ) ;②强迫症组父母的情感温暖因子分低 ,而父母的惩罚、拒绝因子分和母亲的偏爱被试因子分高 ,同正常对照组比较 ,差别均具有显著性或非常显著性意义 (P <0 0 1或P <0 0 5 ) ;③强迫症组EPQ的N因子分明显高于正常对照组 ,而E因子分则明显低于正常对照组 (P <0 0 1)。结论 强迫症患者的防御机制、父母教养方式及个性特征与正常人有着明显的不同 ,它为今后开展分析性心理治疗 ,实施心理干预措施提供了依据。  相似文献

A limited number of studies have paid attention to the psychosocial well-being of patients affected with vitiligo. We review the psychosocial effects of vitiligo, how patients deal with them and the psychiatric morbidity in vitiligo patients. Given the appreciable comorbidity, it is important to consider these observations in the management of patients, for example in patient-physician interaction but also in treatment strategies and evaluation of treatments. The effects of the psychological state on the disease itself together with the potential therapeutic implications are reviewed. Based on these data, we suggest how to further improve patient's management.  相似文献

Objective

To document perceived adherence to treatment (taking medications and performing exercises) in patients with juvenile idiopathic arthritis (JIA) over a 1‐year period and to identify related factors.

Methods

We surveyed parents of patients with JIA at the Montreal Children's Hospital and British Columbia's Children's Hospital in Vancouver. Parents were asked to respond to a series of questionnaires every 3 months over a 12‐month period. Perceived adherence was evaluated on a 100‐mm visual analog scale (VAS) in the Parent Adherence Report Questionnaire (PARQ). Parental coping, distress, child function, disease severity and duration, perceived helpfulness of treatment, problems encountered, and sociodemographic data were also assessed.

Results

The mean age of our sample of 175 children was 10.2 years; mean age at diagnosis was 6.1 years and mean disease duration was 4.1 years. Perceived adherence to medications was consistently high, with average adherence at baseline, 3, 6, 9, and 12 months being 86.1, 91.7, 90.4, 92.0, and 88.8, respectively, on the PARQ VAS. Perceived adherence to exercise was lower but remained steady, with corresponding means of 54.5, 64.1, 61.2, 63.0, and 54.3, respectively. Using generalized estimating equation analysis, factors associated with higher perceived adherence to medications included perceived helpfulness of medications and lower disease severity; those associated with higher perceived adherence to exercise were younger age of the child, child involvement in responsibility for treatment, and higher perceived helpfulness of the treatment.

Conclusion

Belief in helpfulness of treatment is associated with higher parental perceived adherence to treatment.  相似文献

The PK and PS scales of the MMPI‐2 were developed to index the degree of post‐traumatic stress disorder (PTSD). These scales were applied to a sample of 254 mostly male sworn and civilian law enforcement employees from four police agencies. Participants also completed surveys measuring their perceived levels of job stress, their use of a set of coping strategies, and their performance on measures of five global personality domains. The two PTSD scales appeared to have good internal structures and relatively high reliabilities. Employees at greater risk for PTSD reported higher levels of work‐related stress, seemed to use more maladaptive coping strategies, were more neurotic, and tended to be less extraverted, agreeable, and conscientious.
