Development of psychosocial scales for the assessment of adolescents involved with alcohol and drugs.

There are differences among adolescents who use alcohol and other drugs not only in the extent and pattern of their use, but also with respect to the factors that may have contributed to or accompany their involvement with drugs. The Personal Experience Scales (PES) is a new self-report inventory developed to assess psychosocial factors that may: (1) predispose or perpetuate adolescent chemical involvement, (2) complicate chemical abuse treatment, or (3) require treatment in their own right. This paper provides an overview of the development of the PES. Scale construction procedures, scale characteristics, and evidence of scale validity are reported.
