La clarté du concept de soi : validation d’une échelle de mesure en langue française

Introduction The self-concept clarity scale (SCC, Campbell et al., 1996) measures the extent to which self-beliefs are perceived as clearly defined, internally consistent and temporally stable. Objective The study aimed at testing the reliability and validity of a French version of the SCC scale and its relevance to predict the relationship between self-concept and vocational preference. Method Three studies have been conducted on a total sample of 1114 participants (691 women) aged 15 and 62. Results Results revealed that the French version of the SCC had a unidimensional factor structure and high levels of internal consistency and temporal stability (study 1). As predicted, high SCC scores were independently associated with high self-esteem, high conscientiousness, high agreeability, low neuroticism and low social comparison orientation (study 2). Finally, a criterion validity argument was provided by demonstrating that high SCC scores predicted high matching degree between self-concept and occupational preference prototype (study 3). Conclusion The psychometric properties of the French version of SCC are satisfactory and comparable to those of the English original scale. The use of the SCC scale in academic guidance and career counseling is therefore discussed.
