The capability of 14 interpersonal dimensions to predict dyadic communication contexts was investigated in this study. Friend, acquaintance, co-worker, and family contexts were examined. The interpersonal valence construct, based on a coactive or mutual-causal paradigm, encompasses traditional source-valence components (credibility, power, interpersonal attraction, and homophily) plus the factorially distinct components of trust and satisfaction. Multiple discriminant analysis models were used to evaluate questionnaire data from 194 subjects. Eleven interpersonal valence dimensions were used in the predictive equation; 9 of these 11 dimensions were found to be significant predictors of dyadic communication contexts. Methodological considerations and limitations of the present study are discussed. (Author/AA)
