Attachment: the mediating role of hope, religiosity, and life satisfaction in older adults.

<bold>Background: </bold>Attachment and support from family and friends are core to the experiences of ageing for older adults. The purpose of this study is to examine the relationships between attachment styles and hope, religiosity, and life satisfaction and provide new knowledge that may assist future planning for a rapidly ageing global population.<bold>Methods: </bold>In this cross-sectional study, 504 Iranian older adult participants from Qazvin province were recruited between December 2015 and April 2016. They completed a questionnaire that included the Revised Adult Attachment Scale, the Life Satisfaction Index-Z, and the Herth Hope Index.<bold>Results: </bold>Participants in the study had a mean age of 66.20 years (SD: 5.76) and most of them were women (57.5%). A mediation model testing the direct relationships between attachment, hope, religiosity, and life satisfaction showed a positive relationship between close attachment and religiosity (β = .226, p < .001) and a negative relationship between anxiety attachment and religiosity (β =  - .229, p < .001). Religiosity was positively related to hope (β = .384, p < .01) and hope was related to life satisfaction (β = .448, p < .001). Religiosity and hope mediated the relationship between close attachment (β = .119, p < .001) and anxiety attachment (β =  - .056, p < .01) with life satisfaction. More specifically, while religiosity and hope fully mediated the relationship between close attachment and life satisfaction, they partially mediated the attachment anxiety-life satisfaction link.<bold>Conclusions: </bold>Findings of the study provide insight into only a narrow perspective of life satisfaction and attachment given the many and varied variables that influence these constructs. Future research is needed whereby other related variables are introduced into the model to be examined further. [ABSTRACT FROM AUTHOR]
