About Eyberg Child Behavior Inventory
Eyberg Child Behavior Inventory (ECBI; Eyberg & Pincus, 1999) The ECBI is a 36-item parent-rating scale of child disruptive behaviour in children. The Intensity scale measures the frequency with which disruptive behaviour occurs on a scale from 1 (never) to 7 (always) with a range of possible values between 36 and 252. The ECBI Intensity scale yields an internal consistency coefficient of .95 (Eyberg & Pincus); interrater (mother-father) reliability coefficient of .69 (Eisenstadt, McElreath, Eyberg, & McNeil, 1994); and test-retest reliability coefficient of .80 across 12 weeks and .75 across 10 months (Funderburk, Eyberg, Rich, & Behar, 2003).
The ECBI has also shown sensitivity to treatment change (Taylor, Schmidt, Pepler,&Hodgins, 1998; Tynan, Schuman, & Lampert, 1999; Webster-Stratton & Hammond, 1997). Although no minimal difference score has been identified, most treatment researchers use the clinical cutoff of 132 (T-score of 60) as an index of clinical improvement. The ECBIIntensity scale (Cronbach’s α=.90 in the current sample) was used as the outcome measure of child disruptive behaviour.
