A common use of the phrase is when people fear the commitment of marriage and get "cold feet" before a wedding ceremony. This pre-marital doubt or fear may manifest for a variety of reasons and sometimes cause the bride or groom to back out of a planned marriage. Original research on the "cold feet" phenomenon is very limited and warrants further studies.[original research?] However, a four year study conducted by UCLA researchers found feelings of pre-marital doubt or uncertainty about an impending marriage were associated with future marital problems and a viable predictor of divorce.
