In the context of the greying society and limited availability of public-health facilities, long term care for the elderly often takes place in an informal family context, by means of filial responsibility. Previous research shows that attachment bonds between older parents and their adult children can predict adult childrens willingness to provide care for the elderly parents as well as the parent's filial solidarity seeking. The construct of filial maturity has recently been proposed as a predictor of filial elderly care. It describes offsprings ability to perceive parents in a developmental context, as individuals with their limitations, resulting in their ability of comprehending as well as distancing themselves from parents. The aim of this study was to investigate how the attachment orientations of adult children (N = 237) and older parents (N = 143) predict future parent caregiving. The effects of filial maturity dimensions (comprehending and distancing) on future caregiving expectations were explored on the adult children sample. Finally, the correlation between caregiving expectations and the evaluation of life and adult child-relationship satisfaction has been tested. For the purpose of this study, the Filial maturity measure was translated and the Caregiving expectations scale was developed. Therefore, one of the aims of this study was to examine their factor structure and psychometric characteristics. In both samples, the attachment dimensions were connected to caregiving expectations: for the parents, the attachment anxiety was a positive, and the attachment avoidance a negative predictor of caregiving expectations. On the other hand, for the adult children, the dimensions of filial maturity had a significant contribution in predicting caregiving expectations, after controlling for attachment dimensions. A partial mediation effect of the comprehending dimension on the negative effects of attachment avoidance on caregiving expectations was found. Life satisfaction was not connected with future caregiving expectations unlike the adult child-relationship satisfaction.
