Videotaped family interactions were coded using the Relationship Process Code (RPC; Jabson, Dishion, Gardner, & Burton, 2004). Duration scores were recorded to capture the amount of time a caregiver spent prompting and reinforcing the positive behavior of the target child by using the following RPC codes: prompts and suggestions of positive activities, positive reinforcement (both verbal and physical), and positive structure (e.g., providing choices in a request for behavior change). The average team percent agreement for the RPC coding system was .87, kappa = .86.
