目的 考察个体的宗教信仰与完美主义心理之间的关系。方法 采用质的研究方法,对两位受访者(分别为功能障碍型完美主义与健康的完美主义)追行个案研究。结果 两名受访者的基督教(新教)信仰封其完关主义的负面倾向有所矫正,受访者的人际关系和自我认知因为宗教信仰而有所改善。结论 基督教(新教)信仰有利于修正受访者自体表象与权威客体表象的关系。在象征意义上,“上帝”的概念可以理解为“较好的”权威客体表象。 相似文献

Background: Previous studies into leisure have employed methodologies that may understate the significance of experiential components. This exploratory study investigated the leisure experiences of retired Australians over 65 years of age.
Methods: Five semistructured interviews were used to explore the leisure experience of older people from metropolitan Adelaide. Data were coded and analysed thematically.
Results: Relaxation and engrossment emerged as commonly expressed experiences, yet were found to emerge as a result of engagement in occupations predefined as leisure. Experiences of freedom from both necessary duties and a sense of obligation were discussed as potential determinants of leisure consciousness.
Practice implications: This study highlights a need for therapists to actively access clients' subjective leisure experiences to enable engagement in personally meaningful leisure occupations. 相似文献

Clinical decisions are often made with incomplete information, yet patient care decisions are made every day. Patients vary clinically, uncertainty exists in diagnostic and prognostic information, and many preventive and treatment alternatives have not been formally assessed for their effectiveness. Because scientific information will never answer all clinical questions, clinical decisions are partially based on probabilistic information.
This paper describes how to apply clinical decision making to diagnosing and managing dental caries and periodontal diseases. By using explicit information to quantify probabilities and outcomes, clinical decision making analyzes decisions made under uncertain conditions and the uncertain impact of clinical information.
Clinical decision making incorporates concepts for preventing, diagnosing and treating dental caries and periodontal diseases: risk assessment, evidence-based dentistry, and multiple oral health outcomes. This information can serve as a tool for clinicians to augment clinical judgment and expertise. 相似文献

OBJECTIVE: To evaluate variations in prenatal care quality by public and private clinical settings and by household wealth. DESIGN: The study uses 2003 data detailing retrospective reports of 12 prenatal care procedures received that correspond to clinical guidelines. The 12 procedures are summed up, and prenatal care quality is described as the average procedures received by clinical setting, provider qualifications, and household wealth. SETTING: Low-income communities in 17 states in urban Mexico. PARTICIPANTS: A total of 1253 women of reproductive age who received prenatal care within 1 year of the survey. MAIN OUTCOME MEASURE: The mean of the 12 prenatal care procedures received, reported as unadjusted and adjusted for individual, household, and community characteristics. RESULTS: Women received significantly more procedures in public clinical settings [80.7, 95% confidence interval (CI) = 79.3-82.1; P < or = 0.05] compared with private (60.2, 95% CI = 57.8-62.7; P < or = 0.05). Within private clinical settings, an increase in household wealth is associated with an increase in procedures received. Care from medical doctors is associated with significantly more procedures (78.8, 95% CI = 77.5-80.1; P < or = 0.05) compared with non-medical doctors (50.3, 95% CI = 46.7-53.9; P < or = 0.05). These differences are independent of individual, household, and community characteristics that affect health-seeking behavior. CONCLUSIONS: Significant differences in prenatal care quality exist across clinical settings, provider qualifications, and household wealth in urban Mexico. Strategies to improve quality include quality reporting, training, accreditation, regulation, and franchising. 相似文献

This paper is concerned with mothers’ understandings of child health in their young babies. To explore how child health is depicted, explained and contextualised by mothers, altogether 29 mothers in Stockholm and London were interviewed through the baby's first months about day-to-day experiences of the baby's health and well-being. The analysis of the mothers’ accounts reveals how the mothers, in the process of assessing health, try to ‘read’ the bodily signs and reactions in their babies. Some major themes emerge on how the mothers identify and characterise threats to the health of the baby; here described as threats of abnormalities, threats to the survival of the baby, threats to the thriving of the baby and threats from illnesses. Notions of child health are discussed in relation to the ‘bodily’ and the ‘social’, and how the embodied images of child health are intertwined with the mothers’ presentations of themselves as responsible for the health of their children and as ‘worthy’ parents. 相似文献

<正> 中国的计划生育工作和人口控制的进程取得了举世瞩目的成就,中国妇女在这方面做出了巨大的贡献。在目前的生育调节工作中,妇女承担了几乎全部的生育调节和养育子女的责任及义务。社会、家庭甚至妇女本身都默认和接受了这种程式化的规范。 相似文献

The region is characterized by diversity in cultural, political, economic and health conditions. Blindness in the region varies from 6.4% to 0.2% with cataract ranking highly as an underlying cause. There is a need to develop national policies to deliver affordable, technically suitable, and cost effective management plans to reduce cataract. Economic, demographic, health, and manpower statistics are essential information to be considered in formulating such policies. 相似文献
