Behavioral Coding System Reliability (PCIT-BCS)


The Parent-Child Interaction Task (PCIT) was administered to the child and the parent as part of the summer interview in the child's home. Two measures are included in the PCIT: the Behavioral Coding System (BCS; Forehand & McMahon, 1981) and the Interaction Ratings Scale (Crnic and Greenberg, 1990). The PCIT is comprised of four separate segments, which occur in the following sequence: Child's Game, Parent's Game, Lego Task, and Clean-Up. The BCS is used by the child interviewer to record both parent behaviors and child behaviors during each task; the amount of time for each task and the total time are also recorded and used in the scoring of the subscales. The child interviewer then completes the IRS, which is a set of 16 global ratings of the mother and child with respect to gratification, sensitivity, and involvement, after each of the 4 tasks that the parent and child complete together.

Separate methods were used for the BCS and IRS to calculate the reliability checks.

Analysts should note that distribution properties for these scores might be nonnormal due to the small sample sizes involved and the nature of the variable construction. With that in mind, Positive Attention % Agreement and Number of Items with Reliability of Zero were negatively skewed for both the normative and control samples. One score, Sum of Reliability Ratings, was positively skewed for both samples.

Another approach to reliability would have been to calculate the inter-class correlations for these two measures. However, raw data for the lead observer were not available to perform these calculations.
