Stepparent role strain refers to the fragile position of these family members in stepfamilies due to the lack of clear social expectations about their roles. This ambiguity facilitates family conflict and a lack of stepparents' integration into the family system. The aim of this paper is to adapt a pioneer measure of stepparent role strain—the Stepparent Role Strain Index of Whitsett and Land (1992)—in a Spanish sample and to analyze its construct validity. The final instrument is made up of 26 items which have good internal consistency (α = .89) and an underlying six-factor structure, explaining 64.50% of the total variance.

The changing nature of family life has become a major issue in contemporary Britain. Concerns that change will bring moral decline and social fragmentation are countered by a more optimistic view which focuses on a future of more equitable and flexible family ties. Research drawing on area-based data in Luton amongst older, middle-aged and younger people with experience of family change suggests that so far as inter-generational relations, caring, and transfers of family wealth are concerned, traditional attitudes towards blood ties, household independence and care and support survive alongside new step relationships. The research also suggests that although several respondents had more than one generation of experience of family change, the language of step relationships is still one which is not yet completely accepted, or one with which people feel completely at ease.
