The purpose of this research was to isolate and study 2 separate alienation dimensions in relation to other personality characteristics associated with psychopathology. Social alienation and self alienation are conceived as psychological constructs here and distinguished conceptually in the following manner: social alienation is taken here as an individual's sense of detachment from and distrust of his social environment. Self alienation is conceived as an individual's sense of detachment from his own feelings, thoughts, and identity. Personality characteristics, especially those associated with psychopathology, were defined by elevations on the clinical scales of the MMPI. The hypothesis that social alienation would be related to indices of "psychoticism" was partially born out in the significant association between the social alienation scale and the related scales on the MMPI. Results also suggested a relationship between self alienation and "neuroticism;" however, there was a great deal of overlapping of the alienation measures. (RK)
