A study with 130 newlywed couples was designed to explore rnarital interaction processes that are predictive of divorce or marital stability, processes that hrtlier discrin~irzate between happily and urzhappily married stable couples. We explore seven types of process models: (a) anger as a clarzgerou.~ emotion, (b) active listening, (c) negative affect reciprocity, (d) negative start-up by the wge, (e) de-e.scalation, (fi positive affect models, and (g) physiological soothing of the male. Support wa.s not ,found,for the rnodels of anger as a dangerous ernotiorz, active listerzing, or negative affect reciprocity. Support was ,found for n~odels of the husbarzd'.~ rejecting his wife's irzfluence, negative start-up by the wge, a lack of de-escalation of low intensity negative wge aflect by the husband, or a lack of de-escalation of high interz.sity hu.sband negative affect by the wife, and a lack ofphysiological .soothing of the male, all predicting divorce. Support was found for a contingent po.sitive affect model and,for balance n~odels (i.e., ratio models) of positive-to-rzegative affect predicting satisfaction arnong .stable coup1e.s. Divorce and stabilih were predicted with 83% accuracy and sati.Ffaction with 80% accuracy.
