AIM Phenomenological researchers argue that schizophrenia spectrum disorders are primarily disorders of the basic self. To test this argument, we compared self-report and lexical measures of basic self-disturbance between schizophrenia spectrum (high-schizotypy) and non-spectrum groups (low-schizotypy). METHODS From an initial sample (n = 310) screened with the (SPQ), n = 39 were classified as high schizotypy (z > 1.28 on at least one SPQ factor scale) and were compared to a randomly selected low-schizotypy group (z < 1 on all three SPQ factor scales; n = 41). Participants wrote four narratives about personal and fictional experiences and completed the Ego Strength Questionnaire and a self-report version of the Schizophrenia Proneness Instrument. The written narratives were subjected to linguistic inquiry to examine pronoun usage (lexical measures). RESULTS The high-schizotypy group reported higher levels of basic symptoms, lower ego strength, and used third-person and personal pronouns more frequently than the low-schizotypy group. Self-report measures correlated significantly with lexical measures. Self-report and lexical measures were useful tools in predicting high schizotypy, correctly classifying 68% and 69% of schizotypy and non-schizotypy, respectively. CONCLUSION In line with phenomenologists' arguments, high schizotypy was associated, to some extent, with basic self-disturbance.
