This article provides a critical analysis of the Calgary Family Assessment Model using Jacques Donzelot’s work. According to Donzelot, the family is exploited by (para)medical power, and becomes a fertile ground for practices of governmentality. Thus, the family is invited (and “trained”) to play a health provider role in addition to the role of natural caregiver. The (para)medical apparatus imposes itself on the family’s intimacy, alters its functioning, and tenuously governs its conduct. Our analysis shows that Donzelot’s theoretical perspective conflicts with nursing theories.
