Separation-individuation and ego identity status in New Zealand university students
1Department of Education, Victoria University of Wellington, Wellington, New Zealand.
Abstract:
This study explores intrapsychic structures underlying Marcia's ego identity statuses in terms of separation-individuation patterns. It was hypothesized that achievement and moratorium adolescents would give greater evidence of intrapsychic differentiation on a projective measure of separation anxiety than would foreclosure or diffusion youths. Marcia's Ego Identity Status Interview and Hansburg's Separation Anxiety Test were administered to 80 female and 60 male volunteers at a New Zealand university. All were under 23 years of age. As predicted, high statuses showed less anxiety than secure attachment or detachment. Contrary to expectation, no differences among attachment styles appeared for low statuses. Difficulties in adapting the identity status interview to the New Zealand context may partially explain these results. A measure of intrapsychic differentiation provides a useful supplement to the identity status interview.
