Reliability/Validity

The JBC was developed to fill the need for an instrument that could be easily completed by nonprofessionals and measure behaviors of delinquent youths. It has been proven to be accurate, dependable, and of high quality. The majority of studies using the JBC have proven the instrument to be reliable and valid, with good inter-observer and predictive validity.

The normative sample for the JBC consists of 2,114 youths from 13 to 21 years old. Most of the youth were male delinquents in two California Youth Authority institutions. The 235 females in the normative group were on probation.
