Dissociative Disorders and Trauma Inpatient Program

Safe and Secure Care for Individuals in Crisis

Please Note: Treatment in some of McLean’s programs has been moved online due to the COVID-19 crisis.

Please contact the program directly for more information.

At the Dissociative Disorders and Trauma Inpatient Program, we provide comprehensive treatment for adults who live with the effects of childhood abuse or other painful traumatic events.

If you struggle with intrusive thoughts and feelings related to traumatic events, emotional numbing and social isolation, memory difficulties, altered perceptions and personality fragmentation, our program may be right for you. Many trauma survivors also experience intense difficulties with trust and relationships, shame and negative self-images, and self-destructive or suicidal impulses that further complicate treatment.

For more information or to make a referral, please call 617.855.3141.

Our staff is particularly attuned to the needs of our patient population and has extensive experience working with individuals who have presented with such conditions as depression, post-traumatic stress disorder, and personality disorders.

The Dissociative Disorders and Trauma Inpatient Program is ideal for individuals who:

  • Are trauma survivors struggling with an array of symptoms such as intrusive thoughts and feelings, altered perceptions, and social isolation
  • Seek a safe and secure treatment environment focused on stabilization through 24-hour care and support
  • Want to build the skills needed to understand and manage their symptoms to regain control of their lives

The Dissociative Disorders and Trauma Inpatient Program is located in Proctor House, one of several historic buildings on the McLean campus. Though McLean Hospital is located only minutes from Boston, its setting offers a pleasant, peaceful environment that enables patients to focus on improving their mental health. The program facilities offer comfortable bedrooms, common areas for groups and conversation, and access to a fitness facility with state of the art equipment.

Treatment Approach

Over the past decade, the Dissociative Disorders and Trauma Inpatient Program has developed a model of treatment that is highly sensitive to the needs of trauma survivors. Emphasis is placed on the overall psychological health and functioning of the individual and not simply on identifying and working on trauma-related symptoms.

Given the highly chaotic and disrupted early environments of many trauma survivors, we emphasize the need for patients to develop solid relational skills and control of symptoms prior to embarking on the exploration and emotional release of traumatic experiences. Patients are encouraged to acknowledge and deal with traumatic history, while maintaining control, safety, and functioning.

Patients receive help in gaining control over their own experiences so that they can proceed in treatment without being re-traumatized by the intense feelings and experiences that invariably arise throughout treatment.

Treatment at McLean
Our inpatient and partial hospital (day program) service support individuals affected by trauma

We also offer a partial hospital program (day treatment) that provides an intensive care experience for patients who do not require inpatient hospitalization but need a more structured, in-depth form of treatment than is possible in an outpatient setting. Patients may utilize partial hospital services as an adjunct to individual therapy, as a transition from inpatient hospitalization, or as an alternative to hospital care. The partial hospital program runs weekdays per week from 9am to 3pm.

Treatment at all levels emphasizes respect and collaboration, interpersonal relationships, patient education, and healing.
