Adjustment to the transition from high school to military service in Israel was examined in a longitudinal study with a sample of 120 late-adolescent girls. During their senior year in high school (Time 1) the young women were administered the Adult Attachment Interview. Their coping and adjustment to the new environment were assessed (at two further points in time after the transition) by reports of the young women, their mothers, their fathers, and their friends. Young women with preoccupied attachment representations demonstrated the lowest levels of adjustment at both the second and third time points. Young women with dismissing attachment representations did not differ from those with autonomous attachment representations. Satisfaction with social support from parents mediated the association between attachment representations and adjustment (assessed by the young women's reports). (Contains 3 tables and 1 footnote.)
