Using self-concept instruments with high ability college students: Reliability and validity evidence

Abstract: This study investigated the reliability and validity of the academic subscales of Marsh’s Self-Description Questionnaire III and Neeman and Harter’s Self-Perception Profile for College Students for use with high-ability college students. Participants included 100 high-ability college students and 196 average-ability college students enrolled in a com-prehensive university in the South. Data analysis estimates of internal consistency were moderate, and estimates of rela-tionships with external validity criteria, namely, academic achievement, aspirations, and year in school, moderately supported the validity of each subscale. Results indicate some support for the use of each subscale with high-ability college students. Putting the Research to Use: Academic self-concept is a construct that likely affects multiple other academic areas, including academic achievement, educational aspirations, career aspirations, and retention. Among high-ability college students, academic self-concept may be related to participation in an honors program and living in an honors residence hall, which may further the academic, social, and emotional collegiate experience. Having a psychometrically sound measure of academic self-concept that is appropriate for use with high-ability college students will enable researchers to effectively study the academic self-concepts of high-ability college students. Traditional measures of academic self-concept are often validated on younger samples of high-ability students, but the research is lacking on validity research related to samples of college students
