Background The social climate of inpatient facilities is thought to be an important contributor to treatment outcome. However, little research has focused on this construct within secure forensic services for people with intellectual disabilities (ID). Therefore, the objective of this study was to investigate the social climate of two different types of secure units (‘low’ secure vs. ‘medium’ secure) contained within the same facility for offenders with ID. Two hypotheses were generated: (1) residents would rate the social climate of the whole facility in a more negative direction than staff, and (2) residents and staff would rate the social climate of the ‘low’ secure unit in a more positive direction than that of the ‘medium’ secure unit. Method Using a 2 (factor ‘Participant’ = Staff or Resident) × 2 (factor ‘Unit’ = ‘Low’ or ‘Medium’ Secure Unit) between‐subjects design, 18 residents and 37 staff members were recruited and completed the Correctional Institutions Environment Scale (CIES), a measure of social climate. Results Residents tended to rate the units in a more positive direction than staff on some sub‐scales. Participants rated the ‘low’ secure unit in a more positive direction than the ‘medium’ secure unit on two sub‐scales of the CIES. However, on selected sub‐scales there were differences. The findings of this study suggest that the CIES may be a valid instrument for use within forensic services for people with ID, and further suggests that residents and staff have different perceptions of the shared social climate, which may have implications for service development.  相似文献

When children are ill enough to require admission to paediatric intensive care, parents may become distressed about their child's medical condition and this distress may be compounded by the unfamiliar nature of the highly technological environment Parents of children who are sick enough to warrant intubation are particularly likely to be exposed to a frightening array of technological equipment Seventy-one parents of intubated and non-intubated children completed the Parental Stressor Scale Paediatnc Intensive Care Unit (PSS PICU) Overall the findings suggest that parents were most distressed (a) by the painful procedures to which their children were subjected, (b) by the sights and sounds of the intensive care unit and (c) by their children's reactions to intensive care The behaviour of staff towards parents and the way that staff communicated with them caused the least distress When the levels of stress reported by parents of intubated children were compared with those reported by parents of non-intubated children, different patterns of stress were found Painful procedures were a source of greater stress to parents of intubated children whereas the behaviour of staff and the children's reactions to the intensive care experience caused greater stress to the parents of the non-intubated children In general the findings suggest that the needs of parents of non-intubated children are being overlooked, with staff focusing more of their attention on the parents of intubated children  相似文献

Despite being constantly cited as a critical intervening variable in the recovery from alcohol problems, there is a paucity of literature on client motivation. This paper reviews the current literature which impacts on motivation and its importance in treatment and develops in a stepwise manner the revised expectancy/motivation hypothesis, tentatively explaining both motivation and denial as a natural process in behavioural change. Because of the revised expectancy/motivation hypothesis' distinctly defined stages which closely relate to the process of nursing and the qualitative and quantitative measurement it entails which the nursing process demands, it offers a particularly appropriate model for treatment within nurse practice.  相似文献

Approximately 11,550 women with epilepsy give birth annually, yet maternity nurses receive little information on how to care for these patients. Children of epileptic mothers are born with an increased incidence of birth defects, and have a higher perinatal mortality rate. Complications such as bleeding during pregnancy, and interventions such as cesarean births and labor inductions are more common among epileptic women, and seizures tend to increase during pregnancy in more than one-third of epileptic women. Informed nursing care is essential to ensure the best possible outcome of these pregnancies.  相似文献
