Internet-based Emotional Awareness and Expression Therapy for Somatic Symptom Disorder - A Preliminary Efficacy Trial
Background and Aims: This study investigated the feasibility of an Internet-delivered Emotional Awareness and Expression Therapy (I-EAET) for adult patients with somatic symptom disorder (SSD). Although EAET for SSD has been shown to be effective in both individual and group format using RCTs, no trial of an internet-delivered EAET exists. Therefore a preliminary, uncontrolled feasibility and efficacy trial of I-EAET for SSD was conducted. Methods: 124 patients registered to participate, and a structured psychiatric assessment to judge suitability for the treatment was conducted for all patients. A total of 52 patients (50 women, 2 men) were included and initiated treatment. Mean age was 49.6 (SD 11.9). The internet-based treatment protocol consisted of nine modules, which were adapted and translated from the self-help book, Unlearn your Pain by Schubiner. Seven therapists (primarily psychology students) communicated with patients over the internet. Every therapist spent approximately 20 minutes per patient per week to answer question and giving feedback on home-work assignments. Treatment lasted nine weeks. Patients completed measures of somatic symptoms, depression, anxiety, trauma related symptoms, and emotional processing before treatment and again at post-treatment.Results: A large within-group reduction in somatic symptoms (PHQ-15) was observed (d = 1.12; 95% CI: 0.77-1.46). Small to moderate magnitude reductions in anxiety (GAD-7), depression (PHQ-9), trauma related symptoms (PCL-5), and dysfunctional emotional processing (EPS-25) occurred. Almost one-quarter of the sample (23.1 %) achieved a 50 % or greater reduction in somatic symptoms. The treatment also significantly increased patient’s ability to take part in social and family life (Sheehan Disability Scale).Conclusions: I-EAET appears to be a feasible treatment for adults with SSD. Results seems similar or even larger than those obtained in RCTs of EAET delivered face-to-face. A controlled trial is needed determine the effects of I-EAET specifically, and whether this approach might be superior to other internet-delivered treatments. Research should also identify treatment responders and mechanisms of change in EAET.
