The purpose of this investigation is to determine if the Polyfactor test can be used to predict the success or failure of marriage. The Polyfactor test is an indirect scale assessing the present marital adjustment of each spouse and the overall marital adjustment of the couple.

An attempt was made to further establish the validity of the Polyfactor Test of Marital Difficulties, a relatively new, yet potentially valuable sentence completion, self-rating marital difficulties test. . Another test, the Marital Adjustment Inventory was also used for comparison purposes.
