Measures of family members' experiences of integrating chronic conditions (CC) or chronic illnesses (CI) into family life are needed to optimize family care. This article reports development and psychometric testing of the Family Integration Experience Scale: Chronic Illness (FIES:CI), a measure of family member perceptions of integrating CC or CI into evolving family life. Family Systems Nursing (FSN), the Reintegration Within Families in the Context of Chronic Illness Model, and measurement theory guided the study.
