Race and alienation

An alienation score was calculated for MIDUS repondents based on the following items: feels betrayed, deceived; feels exploited; feels mistreated; believes others wish him/her to fail; sees self as target of false rumors; and feels unlucky. Here are the means by race/ethnicity (N = 3,988):

Mean alienation score

White 5.08
Black 6.03*
Amerindian 5.70*
Asian 5.79
Mexican 5.26 

* significantly higher than whites
