This study examined relationships among maltreatment experience, thera
peutic alliance formation, and treatment outcome in a sample of 38 psy
chiatrically hospitalized adolescents. It was hypothesized that the ex
perience of maltreatment would interfere with alliance formation, ther
eby compromising the effectiveness of therapy. Results indicated that
maltreatment, multiplicity of maltreatment, and type of perpetrator of
maltreatment were all associated with initial alliance difficulties.
None of these variables predicted change in the alliance over time; in
stead, severity of interpersonal problems was the best predictor of al
liance development. Maltreatment status was not directly related to tr
eatment outcome; however, maltreated adolescents who failed to develop
positive alliances with their therapists tended to show the poorest o
utcomes. Given the strong relationship between alliance formation and
outcome, clinical recommendations for therapists who treat maltreated
adolescents are presented.
