Measuring Change During Behavioral Parent Training Using the Parent Instruction-Giving Game with Youngsters (PIGGY): A Clinical Replication

This is the second study to investigate the clinical use of the Parent-Instruction Game with Youngsters (PIGGY) which is a structured observation system derived from the Dyadic Parent-Child Interaction Coding System II (DPICS-II; Eyberg, Bessmer, Newcomb, Edwards, & Robinson, 1994) and the Behavior Coding System (BCS; Forehand & McMahon, 1981). In a previous study, the PIGGY demonstrated strong reliability and validity as well as clinical utility (Hupp, Reitman, Forde, Shriver, & Kelley, 2008). The present study is a replication of the previous research on clinical utility by using the PIGGY to monitor changes in parent and child behavior during and after behavioral parent training.
