Self-esteem of ten children with phenylketonuria was compared with that of seven unaffected siblings of children with PKU in a total of 11 families. Ages of the nine girls and eight boys ranged from 8 to 15 years. The study examined several variables that might affect self-esteem. From this study, it appears that PKU status and lowered IQ together contribute to lowered self-concept and that PKU status alone (i.e. with the effects of IQ removed) has a strong tendency to influence self-esteem.
在总共11个家庭中，对10名苯丙酮尿症患儿的自尊与7名苯丙酮尿症患儿的未患病同胞的自尊进行了比较。9名女孩和8名男孩的年龄在8至15岁之间。该研究考察了几个可能影响自尊的变量。从这项研究来看，苯丙酮尿症状态和智商降低共同导致自我概念降低，而且仅苯丙酮尿症状态（即去除智商的影响）就有强烈的倾向影响自尊。
