There are an estimated 56 million orphans and vulnerable children across sub-Saharan Africa. Communities typically care for orphan children through informal caring arrangements – either within or outside of kinship networks. Within Kenya, an estimated 250,000 children live on the streets. There is less research related to fostering attitudes of this special population than orphans and vulnerable children generally. Important research over the past decade has illuminated multiple ways in which children are made more vulnerable because of HIV, including parental death and street-migration from HIV-affected households. As HIV transitions from a terminal illness to a chronic, manageable one, research is also required to establish how parents living with HIV can be an asset to children. In this study, we assess whether mothers living with HIV were very willing to foster biologically-related children, and street-involved children, how these fostering attitudes differed from mothers not living with HIV, and whether differences in fostering attitudes by reported HIV status were mediated by social support, family functioning and general self-rated health. Approximately 40% of mothers living with HIV were very willing to provide long-term foster care to biologically-related or street-involved children. This was less than the percentage of mothers not living with HIV, who were very willing to foster biologically-related children (61%) or street-involved children (58%). Significant portions of these differences were explained by social support, family functioning and general self-rated health. Multi-sectoral approaches are suggested by these findings in order to improve the child-fostering capacity of mothers living with HIV. Improving social support, family functioning and general self-rated health among HIV-infected mothers may not only provide protective benefits for the mothers and their children, but also expand the community’s capacity to care for orphan and vulnerable children. 相似文献

BackgroundThe positive effect of a father’s involvement in children’s upbringing is now recognised. However, research on fathers raising children with autism spectrum disorder (ASD) are still few. This study examines the relationship between the perception, fathers of children with ASD have of the importance of their role in the development of their children and the feelings (self-efficacy, caregiving burden, satisfaction) they express about their parenting experience.MethodSixty-three Swiss Italian fathers of children with ASD completed The Role of the Father Questionnaire (ROFQ), three sub-scales of the Caregiver Survey, a subtest of the Child Adjustment and Parent Efficacy Scale and a home-made questionnaire measuring Perceived Social Support.ResultsThe results from hierarchical multiple regression analyses show that the importance that fathers attach to the paternal role predicts positively their caregiving satisfaction and their feeling of self-efficacy. The children’s challenging behaviours predict positively the caregiving burden whereas the assessment of social support predicts it negatively.ConclusionsThe perception of the importance of the paternal role needs to be considered in the support offered to families with a child with ASD. A better understanding of the fathers’ feelings could be of value for the programmes. 相似文献

ObjectiveAlthough the psychological factors of the work environment affect the quality of employees’ performance more than physical factors, they have not been broadly explained yet. This study is conducted to explore nurses’ perceptions of the co-worker support as psychological resource in the workplace.MethodThe present study is a qualitative research. Fourteen staff nurses who were working in hospitals affiliated to the Khoy University of Medical Sciences, Iran were selected based on purposeful sampling and interviewed using un-structured in-depth interviews. All interviews were recorded, transcribed, and analyzed using conventional content analysis approach through constant comparative method.ResultsData analysis revealed four major themes with 11 sub themes. The four major themes include ‘emotional support’, ‘effective working relationship and collaboration’, ‘suitable social relationships’, and ‘guidance and teaching’.ConclusionThe results showed that, nurses had a positive perception of their colleagues’ support in the workplace. Co-worker support is a multidimensional phenomenon and is influenced by various factors. Perceiving support from the colleague and having a sense of support can promote the quality of care and increase dealing with stressful situations in nursing. Therefore, communication and flexibility skills should be taught to both staff and managers in this regard. 相似文献
