Influence of mental retardation severity and respondent characteristics on self-reported attitudes toward mental retardation and eugenics.

Eugenics refers to the investigation of means of social control to improve the mental or physical qualities of future generations. The present study investigated whether the self-reported attitudes toward mental retardation and eugenics of a sample of 572 respondents would vary as a function of (I) severity of the mental retardation attitude referent; and (2) respondent sociodemographic characteristics. Among the respondents, 380 were health and human service providers (66% upper division undergraduate students and 34% graduate level professionals) and 192 were upper division undergraduate students majoring in fields other than health and human services. The results supported these conclusions: (1) psychometric characteristics of the scales used to measure attitudes were adequate; (2) increasing mental retardation severity was related to increasing endorsement of eugenic principles, independent of global attitudes toward people with mental retardation; and (3) respondent education was related to the expression of eugenic attitudes toward mild mental retardation, while familiarity with people with mental retardation was related to the expression of eugenic attitudes toward moderate and profound mental retardation.
