Page 78 - Personality disorders and insecure attachment among adolescents

participants without a pre-AAI were considered as treatment dropouts because they either withdrew or were excluded, while the duration of their treatment did not exceed the diagnostic two-month phase (61 days) (A. M. de Haan et al., 2013; Swift & Greenberg, 2014). Hence, at pre-treatment, 60 SCID-II interviews in combination with the AAI interview were conducted (see Table 1). The mean age of this pre-treatment sample was 17.8 years (SD = 1.12; range = 15–22), (83.3 % females). The post- treatment sample consisted of 33 adolescents between the ages of 16 and 22 (M = 17.9, SD = 1.3), including 31 females (93.9%) and two males (6.1%). The excluded 27 patients without a post-AAI did not differ significantly from the others in age, gender, severity of symptoms, or personality disorders. The duration of treatment of these patients, however, deviated significantly (M = 256.9 days, SD = 129.4) from the rest of the sample (M = 445.4 days, SD = 113.9). 74
