Abstract
The study focused on the validation of a Self-Concept Scale for Individuals with visual impairment in basic schools in North Central Nigeria. The study adopted an instrumentation and cross-sectional research design. The population for the study was comprised of 398 individuals with visual impairment in basic schools in North Central Nigeria. The instrument for data collection was the research’s developed questionnaire titled “Self-Concept Scale for Individuals with Impairment”. (SCSIVI). The instrument was validated by experts from the departments of English Language, Psychology, Research measured and evaluation and special needs education rehabilitation Kaiser-Meyer – Olkin’s (KMO) measure of sampling adequacy and Barlett’s test of sphericity was used to assess the suitability of data for factor analysis. Also, the principal component analysis (PCA) was conducted to confirm the appropriate number of factors to be extracted. Findings showed that the internal consistency reliability of SCSIVI was determined using Cronbach’s Alpha. The coefficients of .876, .887 and .797 were obtained for physical self- concepts. Emotional self-concept and ideal self-concept respectively were concluded that the instrument SCSIVI was considered valid and it covers the relevant aspects of the construct being measured. The recommendation included among others to conduct longitudinal studies to examine changes in self-concept and identify potential predictors of self-concept development as it will provide valuable insight into the dynamic’s nature of self-concept and its implications for the psychological well–being of individuals with visual impairment.
