The 30-item Decision to Leave Scale (DLS) was developed with 631 college women and 420 college women and women in shelters. Seven DLS subscales emerged for concerns in deciding to stay or leave: Fear of Loneliness, Child Care Needs, Financial Problems, Social Embarrassment, Poor Social Support, Fear of Harm, Hopes Things Change. Mean internal reliability was 0.73, mean test-retest reliability was 0.70. Discriminant validity was demonstrated by expected associations between DLS concerns and self-esteem, children, and violence. Criterion validity was demonstrated by greater DLS concerns for women in shelters than for college women. Women in violent relationships who decided to stay reported more Fear of Loneliness than women who decided to leave. (Contains 2 tables and 2 notes.)
