The aim of this study was to better understand the relationship between parents' experience of caregiving and expressed emotion during the early stage of their child's eating disorder. Fifty mothers and 38 fathers of adolescents suffering from anorexia nervosa and hospitalized for the first time participated in this study. They completed the Experience of Caregiving Inventory, a measure of the negative and positive aspects of the caregiving experience, and the Family Questionnaire, which measured the different dimensions of expressed emotion, namely emotional over-involvement and critical comments. Results showed that caregiving experience is significantly and positively correlated to expressed emotion. Among the negative aspects of caregiving, sense of loss contributed most to emotional over-involvement, while difficult behaviours contributed most to critical comments. The results suggest that parents' perceptions of their child and child's future are strongly related to their tendency to be over-involved. The perception of disruptive behaviours in their child could be one of the principal triggers or exacerbating factors of parents' critical attitudes.
