Assessment of personality and demographic aspects of cohabitation and marital success

The outcomes of 68 marriages of four-year duration were compared on the basis of whether the partners had or had not cohabited premaritally. Background characteristics and personality data were assessed on those couples when there were newly married, and they were followed-up four years later to determine their current marital status, level of satisfaction, difficulty with various problem areas and the number of children born to them. No reliable differences on marital satisfaction or divorce rates between premarital cohabitors and noncohabitors were found. Cohabitors who divorced did so while reporting less marital distress than noncohabitors who divorced. Premarital cohabitors had significantly fewer children than noncohabitors. Degree of difficulty experienced on various problem areas differed between the groups. Certain personality and background variables predicted marital success differently for the two groups. Using the same selected set of six predictor variables, multiple regression equations were generated for cohabitors and noncohabitors. The cohabitors equation (R2 = .56) predicted marital success significantly more effectively than the noncohabitors equation (R2 = .28), When comparing the tri-weight vectors for these two equations, none of the predictor variables had the same influence in both groups. Theoretical implications of the findings were discussed.
