Clinical Outcomes After Temperament Based Therapy With Support (TBT-S): A 12-Month Naturalistic Follow-Up Study.

Area of Science:

• Psychiatry
• Clinical Psychology
• Eating Disorder Treatment

Background:

• Eating disorders (EDs) are complex mental health conditions requiring effective therapeutic interventions.
• Temperament Based Therapy with Support (TBT-S) is a treatment approach for EDs.
• Evaluating the clinical outcomes of TBT-S is crucial for understanding its efficacy.

Purpose of the Study:

• To investigate the clinical outcomes of TBT-S in adult patients with eating disorders.
• To assess changes in ED psychopathology, clinical impairment, anxiety, family functioning, and BMI.
• To examine outcomes over a 12-month follow-up period.

Main Methods:

• A naturalistic 12-month follow-up study involving 46 adult patients with EDs.
• TBT-S was administered as a 5-day treatment.
• Linear mixed models were used to analyze self-reported data on ED symptoms, impairment, anxiety, family functioning, and BMI at multiple time points.

Main Results:

• Patients reported significant reductions in ED symptoms, clinical impairment, and trait anxiety post-treatment and at follow-ups.
• Patients with a baseline BMI < 18.5 showed significant BMI increases at 3, 6, and 12 months.
• No significant changes in general family functioning were reported; patient-reported ED symptom improvements were not mirrored by support-reported changes.

Conclusions:

• TBT-S demonstrates positive clinical outcomes in the first year post-treatment for adult ED patients.
• Improvements were observed in ED psychopathology, clinical impairment, and anxiety.
• Further controlled studies are recommended to rigorously assess TBT-S efficacy compared to standard care.
