The coefficient of explanation and the coefficient of explanation correction were 0.30, indicating that 30% of the changing (variance) in marital intimacy was related to the predictor variables (differentiation and security). The variance analysis show that the regression model fits well with the predictor and criterion variables and the changes explained by the model are real and not accidental.
