The initial standardization of the Adolescent Behavioral Classification Project Instrument

Area of Science:

• Psychology
• Psychiatry
• Behavioral Science

Background:

• Adolescent mental health assessment requires reliable and valid instruments.
• Existing tools may not fully capture the spectrum of adolescent behavioral issues.
• A comprehensive taxonomy of behaviors is crucial for diagnosis and treatment.

Purpose of the Study:

• To develop and standardize an instrument for assessing adolescent behavioral problems.
• To establish a taxonomy of behaviors and persons within an adolescent population.
• To provide a tool for both professional and nonprofessional observation of adolescent behaviors.

Main Methods:

• Collected 482 problem behavior and 30 positive behavior statements.
• Administered statements to institutionalized and non-institutionalized adolescents and their parents.
• Conducted principal components analyses with Varimax and Promax rotations on behavioral and demographic items.

Main Results:

• Developed 25 factors scored on 410 items.
• Internal consistency coefficients ranged from .47 to .86.
• Test-retest reliabilities averaged .71, with a range of .24 to .94.

Conclusions:

• The developed instrument provides a structured approach to adolescent behavioral assessment.
• The resulting factors offer a potential taxonomy for adolescent behaviors.
• The instrument demonstrates adequate reliability and consistency across respondent groups.
