ABSTRACT Establishing trust is an important part of building the therapeutic relationships and achieving the goal of effective trauma treatment for individuals who have experienced childhood sexual abuse. The current study explored the associations between attachment style, therapeutic bond, distress, and interpersonal problems. This study investigated whether attachment style and therapeutic bond mediated the association between the level of early treatment emotional distress and later treatment interpersonal problems among two groups: clients reporting histories of childhood sexual abuse and clients not reporting histories of childhood sexual abuse. Research indicates that disruption of attachment security as well as the therapeutic relationship is common in survivors of childhood sexual abuse. We explored the mediating role of insecure attachment and the therapeutic bond on the predictive relationship between early treatment emotional distress and the interpersonal difficulties that one experiences in their daily life. For clients with histories of child sexual abuse, the model showed that anxious attachment and avoidant attachment mediated the associations between emotional distress and interpersonal relations. Therapeutic bond was not a significant mediator. For clients without histories of sexual abuse, results showed significant association between emotional distress and interpersonal relations, but insecure attachment or therapeutic bond did not mediate this relationship.
