Certain common conditions were noted in a study of nine hospitalized female schizophrenics who demonstrated obvious symbiotic attachments to their mothers. 1. The mother was domineering, castrating, and overprotective, not permitting the daughter any autonomy. 2. The father was passive, ineffectual, and virtually nonexistent as a personality-determining force in the daughter's childhood. 3. Because of reality factors the mother was left more or less isolated with this daughter early in the latter's life. 4. The patient's breakdown occurred during an attempted adaptation to separation from the mother. 5. The maternal grandmother was reported to be a domineering and overprotective person, and the maternal grandfather passive.
