Finally, courtships with high volatility were found to result in lower level of dyadic adjustment and marital satisfaction. Because couples with unstable courtship pattern, compared to those with stable courtship pattern used more negative coping strategies, they therefore developed passive and negative adjustment patterns and may more easily subject to later marital dissolution.
最后,婚前关系起伏程度越高(包括骤热骤冷型、有惊无险及波折丛生型等三种关系发展类型)的夫妻,婚后在夫妻间相互适应的需要度及困难度越高,婚姻满意度也越低;再加上经常使用消极的调适策略,使得婚前关系发展类型较不稳定的夫妻发展出负面或消极的婚姻适应模式,并成为日后婚姻可能解体的危险群。
