The aim of this article is to examine how different ideological perspectives on Swedish disability policy, are reflected in the experiences of disabled people and their families personal assistants. Personal assistance provided within the family can be seen as a hybridization between publicly regulated and paid work performed in the private family sphere, and thus conflicting norms and practices may coexist. In Sweden, family members of the assistant user can be employed as paid personal assistants. Many users combine personal assistance from family members with non-family assistance. Approximately 20–25% of the employed personal assistants are relatives of the assistance users. The empirical data consists of qualitative interviews with seventeen adult users and twenty-three family members employed as PAs with different types of family ties; parent-child relationships, sibling relationships and partner relationships. The findings show that family assistance could entail advantages such as personalised services, to combine instrumental and emotional assistance as well as achieving a power-balance between the parties. But there were also disadvantages, such as unwanted or enforced dependency, with a risk for both parties to be ‘locked up’ in the family. In an overall analysis, we distinguished three broad approaches towards family assistance, family as a substitute, family as a supplement and family first. 相似文献

Perinatal care providers are likely to encounter adverse events such as intrapartum emergencies, traumatic births, or maternal or fetal deaths. As a result of being directly or indirectly involved in an adverse event, health care providers can be considered second victims. The experience of the second victim phenomenon can lead to significant physical, psychological, and psychosocial sequelae that can negatively impact the provider's personal and professional life for either a short or long duration of time. When health care providers experience an adverse event, they may manifest symptoms of guilt, shame, blame, flashbacks, nightmares, insomnia, isolation, helplessness, and hopelessness, thereby becoming the second victim. Following an adverse event, health care providers who experience second victim phenomenon experience stages of recovery that influence subsequent professional and personal well‐being. Persons who experience the second victim phenomenon can incorporate self‐care behaviors to assist with recovery. Health care organizations have a responsibility to implement efficacious support programs that promote the provider's recovery and a return to safe and full function in the workplace. 相似文献

AbstractPurpose: We examined underlying psychosocial processes of a behavioral treatment for urinary incontinence (UI) of prostate cancer survivors.Design: Secondary analysis of data collected from a clinical trial.Sample: Two hundred forty-four prostate cancer survivors who participated in a clinical trial of behavioral intervention to UI as intervention or control subjects.Methods: The participants had a 3-month behavioral intervention or usual care and were followed up for an additional 3?months. They were assessed at baseline, 3, and 6?months. Latent growth curve models were performed to examine trajectories of each study variable and relationships among the variables.Findings: Increasing self-efficacy and social support were significantly and independently associated with more reduction of urinary leakage frequency over time.Implications for psychosocial oncology: Providing problem-solving skills and social support, including peer support, are essential for empowering patients to reduce UI. 相似文献

结直肠癌是常见的消化道肿瘤,其营养不良发生率高且严重。化疗是结直肠癌常见治疗方式之一,并与营养不良独立相关,化疗后患营养不良风险增大且营养不良进一步加重。同时,营养不良可导致患者化疗疗效差及预后不良,并增加化疗相关不良反应、影响患者生活质量及降低生存率等。营养治疗能够有效改善患者营养状况,在肿瘤综合治疗中有重要作用,且多学科团队合作是有效的营养干预模式。目前营养治疗主要包括营养咨询、口服营养补充剂、肠内营养和肠外营养等,相关指南和研究表明在营养治疗时应首选口服营养补充剂及肠内营养,仅在采用以上治疗后仍存在营养不足或无法进行肠内营养时行肠外营养。本文主要对结直肠癌患者营养状况与化疗之间关系、营养治疗的最新研究进展及相关指南进行综述,以期引起临床上对结直肠癌化疗患者营养治疗方面重视并提供参考。 相似文献
