A Trust-Based Intervention for Complex Developmental Trauma: A Case Study from a Residential Treatment Center

This case study, conducted in a Midwest residential treatment center, reports results from an attachment-based intervention that addressed the needs of a 16-year-old female, Rachel. Rachel had a long and documented history of severe abuse and neglect before her adoption from a Bulgarian orphanage at age 12 and numerous psychiatric hospitalizations in the years subsequent. Upon entering this residential treatment center, Rachel did not respond to traditional residential treatment modalities and was considered one of the most difficult children the facility had ever attempted to help. After the intensive attachment-based intervention for Rachel, her adoptive parents, and facility staff, dramatic increases in pro-social and attachment behaviors were noted, as well as a significant decrease in violent and self-injurious behaviors. The intervention consisted of three phases of differing levels of intensity and was designed to address the attachment system and related sub-systems in order to facilitate the development of healthy attachments.

Commentary on Treatment of Infertile Couples Using Reproductive Technologies: A Complex Matrix

The impact of the reproductive technologies upon infertile couples who require them is both ubiquitous and profound. There is a confluence of issues that co-exist for women and men who use reproductive technologies which creates a complex matrix for both the analytically informed social work clinician and those seeking infertility treatment. The unique merger of life stage issues, identity issues, cultural pressures, and responses to the physical and emotional demands of the necessary technologies, serves to amplify the intensity of encounters in this analytic triad. Consideration of attachment theory while utilizing intersubjective systems theory provides a system of treatment which offers comfort and a place to mourn the multiple losses of repetitive failures of attempts to conceive.

A Long-Term Family-Oriented Treatment for Adolescents with Substance-Related Disorders: An Outcome Study

Treatment programs for substance-disordered adolescents increasingly use family and Twelve-Step orientations. Pathway Family Center adds to that model a long term stay (9 to 15 months), a day treatment setting, and the unique feature of temporarily placing the client with the family of another client who has progressed further in the program. This outcome study surveyed the 100 clients and their parents from the first five years of the program, using mailed questionnaires and telephone interviews. Information was collected from 51% of clients and 61% of parents, and client-parent agreement was high. Ninety-eight percent of adolescents reported that they did not return to prior drug severity, 51% reported no use since discharge, 23% reported one or two relapses, 88.2% reported improved family relations, and 90.2% reported improved quality of life. In comparing those who remained completely abstinent with those who relapsed, the non-relapsers were twice as likely to have a diagnosis of uni-polar depression at admission. We hypothesize that the depression is associated with hitting bottom, an indication that the client may be motivated to commit to major change. These outcomes compare very favorably with those of other adolescent treatment programs.
