The purpose of this study was to develop the scale to measure the level of symmetry-complementarity (Bateson, 1936) in dyadic conversation and to test the reliability and the validity of the scale. I developed the 25 questionnaire items and selected 13 items based on the result of item-total correlation analysis. The Cronbach’s coefficient alpha of the scale was .87, the intra-class correlation coefficients was .58 (p <.01) and the correlation between the total scores of the SSCC and actual communication score evaluated by the coding system (FRCCCS ; Heatherington & Friedllander, 1987) was .64 (p<.01). The results indicated that the Scale on Symmetry and Complementarity in Conversation (SSCC) possesses high internal consistency, inter-rater reliability and criterion-referenced validity.
