A Biopsychosocial Treatment for Exhaustion Due to Persistent Non-traumatic Stress

Currently, there are no established theoretical models for developing and maintaining Exhaustion due to persistent non-traumatic stress (ENTS). Therefore, the current pilot study aims to evaluate a Multimodal hybrid intervention built around an internet-delivered cognitive behavioral therapy based on a new biopsychosocial treatment model of ENTS.

Since 2009 long term sick-leave rates due to mental disorders have been increasing in Sweden and are today the leading cause of long-term sick leave. Exhaustion due to persistent non-traumatic stress (ENTS) accounts for most of this increase. Unfortunately, despite several published treatment studies, no evidence-based treatments exist for ENTS, and little is still known about the focus of treatment. Currently, there are no established theoretical models for the development and maintenance of ENTS. Many of the published clinical ENTS trials consist of long (6 months or more) Multimodal interventions (MMI) containing various medical, psychological, and physiotherapeutic methods with a low degree of understanding of what components are critical for treatment success. Even if ENTS patients participating in MMI report symptom improvements and work resumption, MMI is generally personnel intensive and challenging to administer. These factors increase the risk of extended healthcare lead times and obstruct treatment dissemination. Considering the increasing sick-leave rates due to ENTS, there is an apparent need for more accessible treatments based on pronounced theoretical models focusing on specific change processes. Therefore, the current pilot study aims to evaluate a hybrid MMI built around an internet-delivered cognitive behavioral therapy based on a new biopsychosocial treatment model of ENTS. Outcome measures will be collected before and after treatment and at three and six-month follow-ups. Weekly measurements of putative processes of change will also be collected. The current study aims to evaluate whether this more restricted and theoretically coherent hybrid MMI shows promising results before we test the treatment solely as a cognitive behavioral therapy via the internet in a randomized controlled trial.
