Dimensions of Abortion Decision Difficulty (DADD) Scale

The Dimensions of Abortion Decision Difficulty (DADD) Scale is a 12-item measure that captures the ease or difficulty with which women decide to have an abortion. The DADD scale includes these four dimensions: (1) unrealistic fears about the abortion and fantasies about the pregnancy; (2) decision conflict; (3) negative abortion attitudes; and (4) general indecisiveness.
