- An important question is whether triadic interaction tasks provide additional information beyond dyadic tasks. We examined this issue in 103 triads of parents and twin pairs from the longitudinal Western Reserve Reading Project (WRRP). The triads analyzed were those who had participated in the Year 1 home visit assessment portion of WRRP. Aspects of triadic interaction were assessed from an 8-10 minute videotaped triadic domino task which was part of a larger 55 minute videotaped observation set. The dyadic interactions which preceded and followed the triadic task were coded using the Parent Child Interaction System (PARCHISY) and the triadic task was assessed using the proposed Triadic Interaction Coding System (TRICSY). The results showed that the proposed TRICSY coding scheme was a reliable assessment and coding instrument for the triadic domino task recorded in Year 1 of WRRP. There were no significant mean differences in the variables assessed in both the dyadic and triadic coded tasks. Additionally, there was no support for significant differential parental feelings, attitudes, or treatment as assessed in the study. Correlation analyses showed there were both similarities and differences in the relationships between the twelve measured variables shared by both the dyadic and triadic tasks. The results also indicated that the TRICSY triadic task coding scheme was not any more effective than the PARCHISY dyadic task coding scheme at predicting concurrent or future externalizing behavioral problems as indicated by HLM analyses. In conclusion, the TRICSY coding scheme was found to be a reliable instrument for coding the triadic interaction observed in the study but, the scheme did not provide any additional ability to describe or predict outcomes beyond that provided by the dyadic PARCHISY scheme.
