The Fraboni Scale of Ageism (FSA) is introduced in this study with reports of its factor structure, internal consistency reliability, and its relationship to The Acceptance of Others Scale, The Facts on Aging Quiz, and The Marlowe-Crowne Social Desirability Scale (N = 231). The FSA construct is derived from Butler's (1978) definition of ageism, and is intended to measure the affective component of attitude to supplement the cognitive aspect measured by other instruments. The FSA was found to have adequate construct validity and high internal reliability. Relationships to the other constructs measured supported the uniqueness of the FSA and revealed a lack of influence from social desirability. Sex was found to account for some variance in FSA scores.
