One hundred twenty-four participants (20.7%) met the diagnostic threshold for ODD on the WRAADDS. Using these case assignments to estimate indicator validity, the eight SR-WRAADDS ODD items had very good indicator validity (Table 1). Alternatively, when the MAMBAC and MAXEIG procedures were used to generate a base rate estimate, this average estimate of 23% also yielded strong indicator coefficients (Table 1).
