摘要：background Self-concept clarity is one of the features describing the structural aspect of the self.It refers to the extent to which the contents of an individual’s self-concept are clearly and confidently defined,internally consistent,and temporally stable.The aim of the study was to translate and evaluate the psychometric properties of the Polish version of the Self-Concept Clarity Scale (SCCS).participants and procedure A total of 2507 graduates and undergraduates participated in the study.Their ages ranged from 18 to 70 years (M = 24.74,SD = 23.00);66% of them were female.The Polish version of the SCCS was developed using the back-translation method.The SCCS was administered along with measures of sense of self (Sense of Self Scale),self-esteem (Rosenberg Self-Esteem Scale),psychological distress (Goldberg General Health Questionnaire),personality (NEO-Five Factor Inventory),and social desirability (Marlowe-Crowne Social Desirability Scale).results The factor structure,reliability,and validity of the scale was investigated.Results from exploratory and confirma_tory factor analysis showed a one-factor solution.Internal reliability and test–retest reliability was high.Significant relations between SCCS and weak sense of self,self-es_teem,psychological distress,personality,and social desir?ability supported its convergent validity.conclusions This study demonstrated that the Polish version of the SCCS is a reliable and valid self-report measure for the self-concept clarity.
