Objectives: This study examined interrelationships of the Adolescent Self-Determination Assessment-Short Form (ASDA-S) from the following: (a) the ASDA-S and the AIR Self-Determination Scale and (b) the ASDA-S and the Adolescent Self-Determination Scale (ASDA; the original form of the ASDA-S). Methods: To identify the underlying relationship between latent constructs of measures of self-determination, structural equation modeling (SEM) techniques tested the proposed measurement model investigating the ASDA-S as distinct or similar constructs measured in the AIR-S and the ASDA, including 1786 adolescents and young adults with and without disabilities. Results: The development of higher-order constructs of the ASDA-S and the AIR represented that domains statistically supported the theoretical perspectives in each measurement. In addition, the interrelationship between the ASDA-S and the ASDA reported a strong relationship. Conclusions: The magnitude of interrelationships between the ASDA-S with the AIR-S established concurrent criterion-related validity. By confirming the validity of the ASDA-S with youth with and without disabilities, the measurement ensured a potential usage for schoolwide and inclusive settings.
