"Finding Solid Ground" in Inpatient Treatment for Dissociative Disorder Patients Followed by Transition to Outpatient Treatment Settings: A 1-year Follow-up Pilot Study

March 7, 2026 updated by: Modum Bad

Inpatient Group and Individual Trauma- and Dissociation Informed Stabilization Therapy for Adult Survivors of Childhood Trauma

The purpose of the pilot is to examine the usefulness of the psychoeducational program, Finding Solid Ground, for patients with dissociative disorders in a naturalistc observational study, involving a 3-months inpatient treatment followed by patients continuation with the program in their local outpatient settings, by examining outcome of main trauma-related symptoms and adaptive coping. In addition, performing focus-group interviews with the patient groups at discharge and at follow-up, to gain information on their subjective experiences from participating in the program. The patients' therapists in the outpatient settings are invited to give written feedback on their experiences from working with FSG.

Detailed Description

Adult survivors of childhood trauma have complex and diverse symptoms profiles. A subgroup develop a complex dissociative disorder. Modum Bad has for years offered a 3-months inpatient treatment program for this patient group. Patients leave the hospital after this treatment period and continue with treatment in their local outpatient settings. They come back for a 5-days follow-up 9 months after discharge from the residential setting. The aim of the pilot study is to examine changes in posttraumatic and dissociative symptoms and adaptive coping in this patient-group within the described naturalistic context, following patients' participation in Finding Solid Ground (FSG). FSG is developed by dr Bethany Brand, dr. Hygge Schielke, and dr Ruth Lanius (2022), and designed for this patient-group. It has 30 topics. Patients start up with FSG and complete 8 topics in the inpatient setting, and are offered to continue with the remaining topics during the outpatient period in collaboration with local treatment providers. 32 patients were recruited. Two of them were not included: one did not want to participate, and the other patient had a different focus in her treatment than FSG. Patients were assigned from referrals to the residential Department for Trauma treatment, Modum Bad, in Norway. As part of the usual clinical practice they were referred to our treatment group if they had a complex dissociative disorder in need of stabilization. The inpatient treatment lasts for 11 weeks and combines group- and individual therapies with different treatment modalities, all within the framework of FSG. Patients came back for a 5-days follow-up stay, 9 months after discharge from the inpatient treatment.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

They are selected from patients referred to treatment in the Department for Trauma Treatment, Modum Bad, and have been routinely evaluated for treatment in this department, diagnosed with a dissociative disorder and in need of stabilisational interventions.

Description

Inclusion Criteria:

  • The study include adults (minimum age of 18 years) with a complex dissociative disorder related to childhood trauma. All patients had received outpatient therapy with insufficient effect. Patients were diagnosed with at DSM-IV dissociative disorder, transformed to the ICD-10 dissociative disorders.

Exclusion Criteria:

  • Ongoing psychosis, severe ongoing drug addiction, very disturbed group functioning, ongoing severe life crisis, mental disability, severe unsafe behavior (suicidality, self-harm).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Adults with compelx dissociative disorders and histories of childhood trauma
All group and individual therapies were in line with the model presented in Finding Solid Ground, developed by dr. Bethany Brand et al. (2022). Patients were admitted for the inpatient pre-planned treatment for a 3-months period, continue with therapy in their local outpatient settings after discharge from the inpatient period, and come back for a 5-days follow-up stay 9 months after discharge from the inpatient treatment.
Behavioral: Psychotherapy
Patients are admitted in groups of eight. During the 3-months inpatient treatment period, the program include a daily group session, and 3 weekly individual sessions with individual therapists and milieu-therapists, with focus on FSG-interventions from a trauma- and dissociation-informed perspective. FSG follows the international guidelines (ISSTD, 2011) for treatment of dissociative disorders from the International Society for the Study of Trauma and Dissociation. It uses different treatment modalities, such as live psychoeducation, psychoeducational videos, written and practical exercises, equine facilitated therapy, reflection and discussion groups. They have parallel individual therapy with therapist (psychiatrist or psychologist) and milie-therapists, and participate in physical activity and ward meetings together with other patients in the unit. All therapists are trained in trauma- and dissociation therory and treatment, as well as the FSG model.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progress in Treatment Questionnaire (PITQ-p)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
