The Age Group Evaluation and Description (AGED) Inventory: a new instrument for assessing stereotypes of and attitudes toward age groups.

The AGED Inventory was designed to overcome shortcomings identified in the Aging Semantic Differential, a frequently used measure of how age groups are perceived. The new instrument was developed to allow assessment both of age stereotypes and of attitudes toward age-specified targets. The Inventory was developed with data from 300 male and 300 female respondents. Two seven-item evaluative factors (the Goodness and Positiveness dimensions) resulted from a series of factor analyses used to reduce an initial set of thirty-five evaluative adjective pairs. Two seven-item descriptive factors (the Vitality and Maturity dimensions) resulted from a separate series of factor analyses used to reduce an initial set of fifty adjective pairs judged to differentiate age groups. Using confirmatory factor analyses and coefficients of congruence on data from an additional 800 respondents, the factor structures of the two evaluative factors and of the two descriptive factors were found to be replicable for young, middle-aged, and old targets assessed in either between or within subject designs. Its ease of administration, multidimensionality, flexibility of targets specification, and capability for assessing attitude and/or stereotype in a manner congruent with current conceptualizations of these constructs make the AGED Inventory useful in a variety of contexts.
