The document reports results of a study which integrated two models of political alienation--the social deprivation and the political reality models. The social deprivation model was originally conceived to measure feelings of social inefficacy and political distrust among black preadults. It is argued that the model is equally pertinent to white and adult populations. The political reality model predicts a direct association between critical-threatening perceptions of the sociopolitical system and feelings of political inefficacy, discontent, cynicism, and estrangement. A random sample of 460 white and black senior high schools students in Evansville, Indiana, responded to a self-administered questionnaire. A majority of the sample was female (52%) and white(91%). Three major findings resulted. First, predicted differences between white and black adolescents regarding levels of perceived social deprivation, perceived self-competence, critical-threatening perceptions of sociopolitical reality, and feelings of political alienation do not occur. Second, predicted correlations between variables in the model received little empirical support for either racial group. Third, in predicting levels of perceived political alienation, the social deprivation-political reality model seems more applicable to white than to black adolescents. (Author/KC)
