The Stepparent Relationship Index: Development,validation, and associations with stepchildren’s perceptions of stepparent communication competence and closeness

There is a growing consensus among family researchers that many of the challenges facing members of stepfamilies revolve around the role of the stepparent. Using schema theory, this study extends recent research on the stepparent role by developing an empirically reliable measure for the primary dimensions that stepchildren identify as part of their stepparent relationship schemas. Participants included 522 young adult stepchildren from 4 different states who completed an inventory assessing key dimensions of the stepparent‐stepchild relationship, as well as stepchildren’s perceptions of stepparents’ communication competence and closeness. The results produced a new multidimensional measure, the Stepparent Relationship Index, as three dimensions of the stepparent‐stepchild relationship emerged from factor analytic techniques: positive regard, (step)parental authority, and affective certainty. Each subscale produced acceptable reliability estimates, and initial evidence of concurrent validity was obtained.
