Among psychological factors, disturbances of "object-relations" and "separationindividuation" are proposed as causes of a narcissistic fixation upon the body, and other manifestations of "self" disturbance, like driven perfectionism and self-regulation problems (e.g., Goodsitt, 1983;Schwartz, 1988). Consistent with the notion of "self" disturbance, empirical data indicate very high prevalences of personality disorders in EDd groups (e.g., Gartner, Marcus, Halmi, & Loranger 1989; Wonderlich, Swift, Slotnick, & Goodman, 1990), and theoretically related problems, like immature defenses (Steiger, Van der Feen, Goldstein, & Leichner, 1989;Steiger et al, 1990) and instability of "object-relations" (Humphrey, 1986; Steiger et al, 1990).…”
