CONSTRUCTION AND PSYCHOMETRIC EVALUATION OF THE EGO-IDENTITY STATUSES QUESTIONNAIRE SID48

Summary/Abstract: The developmental-structural model of the status of self-identity is an empirically based elaboration of Erikson’s theory of psychosocial personality development. This psychoanalytical model has inspired many studies and the development of measuring instruments, which, however, have unsatisfactory psychometric characteristics. Therefore, for the purposes of the research, the SID48 questionnaire, which measures individual differences in four self-identity statuses, was constructed and later tested on national samples. Based on theoretical assumptions and concepts, we first created an initial sample of 200 items, and then a 60-item test version of the questionnaire, with five-level scales of graded answer categories attached. The experimental version of the questionnaire consists of four scales with 15 items each, which should measure the individual differences in the statuses of achieved and assumed self-identity, confusion, and moratorium with sufficient reliability and validity. The questionnaire was applied together with other instruments of the same type on a convenient sample of 458 respondents of both genders (60% female) and aged 19 to 33 years. The data generated in this way were analyzed on two occasions in order to check the internal psychometric characteristics. The result is the SID48 questionnaire with four scales containing 12 items each. The SID48 questionnaire has very good to excellent representativeness, homogeneity, reliability, and factorial validity.
