Abstract
Although current divorce rates indicate an unprecedented instability in marriages, a satisfied relationship still belongs to the most important determinants of life satisfaction as well as physical and mental health in human beings. Plenty of research in this field identified couple competencies as robust and internationally consistent predictor of divorce. This article reviews current findings on psychological predictors and theoretical approaches how and why negative interaction in couples may end in divorce. These results are clinically relevant and may be considered as encouraging since dyadic competencies are promisingly delivered in relationship distress prevention programs.
