“…Research also suggests that adopted children are more likely to manifest various forms of acting-out behavior and/or conduct disorders than their nonadopted counterparts, especially aggressiveness, oppositional behavior, impulsivity, hyperactivity, and running away (Austad & Simmons, 1978;Brodzinsky, Radice, Huffman, & Merkler, 1987;Dalby, Fox, & Haslam, 1982;Fullerton, Goodrich, & Berman, 1986;Kotsopoulos et al, 1988;Lindholm & Touliatos, 1980;Menlove, 1965;Weiss, 1985). Furthermore, adoptees have been reported to manifest a higher incidence of personality disorders (Lindholm & Touliatos, 1980;Schechter, Carlson, Simmons, & Work, 1964;Simon & Senturia, 1966), but either no difference in or a lower incidence of psychotic disorders (Brinich & Brinich, 1982;Fullerton et al, 1986;Lindholm & Touliatos, 1980;Schechter et al, 1964;Weiss, 1985).…”
