A series of "world view" questions was utilized in generating scale scores that sharply differentiated representative samples of Chicanos (280), Blacks (280), and Anglos (413) in a longitudinal study with a 1960 baseline. Seventy-five percent of the original respondents were reinterviewed in 1971, indicating both Chicano and Blacks held views more comparable to Anglo views than they did in 1960. (JC)
