Self-discrepancies: Measurement and relation to various negative affective states

This study examined the validity of two methods for assessing self-discrepancies: an idiographic method (The Selves Questionnaire, SQ) and a nomothetic method (Adjective Rating List, ARL). It also tested several major hypotheses of self-discrepancy theory regarding the relations between self-discrepancies and emotional discomfort. SQ and ARL scores from 220 participants demonstrated moderate correlations between instruments and high intercorrelations between discrepancy scores within instruments. Self-discrepancy scores were related to negative emotional states, but the specificity of these relations was not demonstrated, nor did they make a substantial contribution to the prediction of negative emotional states after controlling for negative self-concept. Overall, these findings raise significant concerns about the relevance of self-discrepancies as measured by the SQ and ARL and fail to support the main contentions of self-discrepancy theory.
