The study outlined has three goals: first, to find the dimensions of variation among nations with respect to their dyadic conflict behavior over a continuous series of months and to compare these month to month dimensions with dimensions derived through employing an annual time frame; secondly, to ascertain the groups of nation dyads that exhibit similar patterns of conflict behavior over time; and thirdly, to discuss the profiles of dyadic conflict behavior for each of the groups delineated in the analysis. Data have been collected on several measures of foreign conflict behavior over 275 dyads for 1963. These data will be reorganized into 12 month periods, intercorrelated, and factor analyzed. The factors derived from this analysis will then be compared with those derived from a 1963 study. Factor scores for each dyad will be calculated to determine its position along the foreign conflict dimensions.
