Rachel Stryker in her anthropological study ""The Road to Evergreen"" argues that adoptive families of institutionalized children who have difficulties transitioning to a nuclear family are attracted to the Evergreen model despite the controversy, because it legitimises and reanimates the same ideas about family and domesticity as does the adoption process itself, offering renewed hope of "normal" family life. Institutionalized or abused children often do not conform to adopters conceptualizations of family behaviours and roles. The Evergreen model pathologizes the child's behaviour by a medical diagnosis, thus legitimising the family. As well as the promise of working where traditional therapies fail, attachment therapy also offers the idea of attachment as a negotiable social contract that can be enforced in order to convert the unsatisfactory adoptee into the "emotional asset" the family requires. By the use of confrontation the model offers the means to condition children to comply with parental expectations. Where the therapy fails to achieve this the fault is attributed to the child's conscious choice to not be a family member, or the child's inability to perform as family material.
