Despite advances in methodology and instrumentation, the assessment of adol
escent drug and alcohol involvement remains a complex clinical and practica
l process. It requires the careful and skillful implementation of procedure
s across a wide range of service systems and providers. While the literatur
e identifies and provides information on singular aspects of the assessment
of adolescents, few sources furnish an integrated overview of the key issu
es necessary for appropriate and accountable assessment. Consequently, this
paper synthesizes theoretical, research, and clinical issues into a practi
cal framework that can be used by clinical and research staff making assess
ment decisions. Issues discussed have been informed by the literature and b
y our collective experience during the 8-year development and testing of th
e Comprehensive Adolescent Severity Inventory (CASI). (C) 1999 Published by
