This study examined similarities and differences between blacks' and whites' responses to rarely endorsed Minnesota Multiphasic Personality Inventory (MMPI) items, as well as those items responded to most differently by the ethnic groups. Our subjects, 882 normal black middle-class adults from Alabama, Michigan and North Carolina, were compared to the Minnesota normative sample. White endorsement patterns agreed with items rarely endorsed by blacks, but black endorsement patterns agreed with only one-third of the items rarely endorsed by whites. This new race-sensitive F scale may be a better measure of deviant responding for blacks than the standard scale. Race-discriminating items suggested that blacks (in comparison with whites) emphasized feelings of self-importance, were relatively cynical about motives controlling behavior, and tended to be alienated and unhappy. Whether this characterization is accurate or an artifact of the item content of the MMPI cannot be answered by data currently available. (Author/GDC)
