Abstract

The construct of maturity is often discussed in the realm of adolescent development; however, relatively little research has been devoted to developing a comprehensive, reliable, and valid measure with which to assess it. The purpose of this study was to investigate the concurrent validity of the Montana Adolescent Maturity Assessment - III (MAMA-III), a proxy measure completed by clinicians regarding an adolescent's functioning, with the immaturity scale (IMM) of the MMPI-A. To provide more specified results, a factor analysis of the IMM was undertaken. Results yielded a low but significant correlation between the MAMA-III and the IMM, as well as significant convergent correlations between individual factors of the MAMA and IMM scales. Correlations among the MAMA-III factors, the IMM factors, and the ten clinical scales of the MMPI-A were also analyzed with the goal of better understanding what each measures. Implications are discussed regarding the clinical distinctions between the two measures, and the prospect of a more comprehensive understanding of the construct of maturity.
