Background: Emotional intelligence (EI) is increasingly discussed as having a potential role in medicine, nursing, and other healthcare disciplines, both for personal mental health and professional practice. Stress has been identified as being high for students in healthcare courses. This study investigated whether EI and stress differed among students in four health professions (dental, nursing, graduate mental health workers, medical) and whether there was evidence that EI might serve as a buffer for stress., Method: The Schutte Emotional Intelligence and the Perceived Stress scale instruments were administered to four groups of healthcare students in their first year of study in both the autumn and summer terms of the 2005-6 academic year. The groups were undergraduate dental, nursing and medical students, and postgraduate mental health workers., Results: No significant differences were found between males and females nor among professional groups for the EI measure. Dental students reported significantly higher stress than medical students. EI was found to be only moderately stable in test-retest scores. Some evidence was found for EI as a possible factor in mediating stress. Students in different health profession courses did not show significant differences in Emotional Intelligence., Conclusion: While stress and EI showed a moderate relationship, results of this study do not allow the direction of relationship to be determined. The limitations and further research questions raised in this study are discussed along with the need for refinement of the EI construct and measures, particularly if Emotional Intelligence were to be considered as a possible selection criterion, as has been suggested by some authors.

Background: Dementia is an important health and social care problem and is one of the main causes of disability in later life. The number of families affected by dementia will dramatically increase over the next five decades. Despite the implications for health and social care services in the future, the overwhelming majority of care for people with dementia takes place away from health care settings. Providing informal care for someone with dementia can be psychologically, physically and financially expensive and a range of health service interventions aimed at supporting and providing information to these carers has developed to help carers meet these demands. This review examines whether information and support interventions improve the quality of life of people caring for someone with dementia., Methods: A systematic review examining evidence from randomised controlled trials in which technology, individualised or group-based interventions built around the provision of support and/or information were evaluated., Results: Forty-four studies were included in the review. Controlling for the quality of the evidence, we found statistically significant evidence that group-based supportive interventions impact positively on psychological morbidity. However, whilst the improvement was unlikely to be due to chance, the clinical significance of this finding should be interpreted tentatively, due to the difficulties in interpreting the standardised mean difference as a measure of effect and the complex aetiology of depression. No evidence was found for the effectiveness of any other form of intervention on a range of physical and psychological health outcomes., Conclusion: There is little evidence that interventions aimed at supporting and/or providing information to carers of people with dementia are uniformly effective. There is a pressing need to ensure that supportive interventions at the development stage are accompanied by good quality randomised evaluations in which outcomes that are important to clinicians and carers are measured.
