This study is meant to explore the psychometric properties of The Self-Advocacy Skills Inventory Beta. The Beta is a measurement of self-advocacy skills for individuals with different disabilities. This dissertation presents the results of a confirmatory factor analysis, as well as an examination of reliability of the Beta as well as its scales. The results of the confirmatory factor analysis indicated that the theorized factor structure of The Self-Advocacy Skills Beta did not fit the data. However, the Self-Advocacy Skills Inventory Beta is measuring self-advocacy skills reliably. Implications for counseling education and future development of The Self-Advocacy Skills Beta are discussed.
