Clinical Trial Summary

Inpatient treatment for patients with anorexia nervosa (AN) is recommended in extreme or severe cases after failure of outpatient treatment and is highly effective. However, a number of patients show symptom increase and relapse after discharge. The aim of this study is to evaluate the efficacy of a guided smartphone-based aftercare intervention following inpatient treatment of patients with AN to support symptom stabilization or continued improvement.

Description:

Anorexia nervosa (AN) is a severe, often chronic and life-threatening disorder. Relapse after treatment is common with relapse rates ranging between 9 and 52% and being highest within the first year following treatment particularly as early as 3 months posttreatment. Even if weight restoration is achieved, it is quite difficult for patients to sustain improvements after treatment, so aftercare and relapse prevention are essential research topics. There is a recent review on internet- and mobile-based aftercare and relapse prevention in mental disorders that concludes that there is some evidence that such interventions are feasible instruments for maintaining treatment gains for some mental disorders, including eating disorders (EDs). However, the authors claim for further high quality, large-scale trials that are needed to expand research fields. So, the aim of this study is to prove the efficacy of a guided smartphone-based aftercare intervention for inpatients with AN. Our primary hypothesis is that at the end of aftercare intervention (T1), the intervention group shows a significantly lower eating disorder symptomatology than the control group.

Eligible patients with AN who are discharged from inpatient treatment are randomized either to receive a 4-month smartphone-based aftercare intervention with therapist feedback as an add-on element to treatment as usual (TAU) or TAU alone. Assessments include structured interviews as well as online questionnaires and are taken at baseline (discharge, T0), end of the aftercare intervention (T1) as well as 6-month follow-up (T2).

Intervention

Behavioral:
• Recovery Record aftercare
Patients randomized to IG receive a therapist-guided smartphone-based aftercare intervention for a period of 16 weeks. The patients are invited to download for free the German version of "Recovery Record" at the App Store (iPhone) or the Google Play Store (android) to their smartphone and to link with the aftercare therapist. After discharge, patients are asked to monitor their meals at least three times per day (breakfast, lunch, and dinner), that is, to produce a minimum of three logs per day over the subsequent 16 weeks. Furthermore, patients are instructed to monitor their thoughts and feelings as well as their (disordered) behaviors. The aftercare therapist also sets the patients clinical post-discharge goals and makes coping skill suggestions. Individual therapist feedback is provided in-app twice per week during the first four weeks, once per week in weeks 4-8, every other week in weeks 8-12 and once in week 16.
• Treatment as usual (TAU)
Patients randomized to CG receive TAU i.e. patients and their physicians or therapists decide on post-discharge treatment which is documented at T1 and T2.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in Eating Disorder Severity (assessor-based)	The Eating Disorder Examination (EDE) will be used to measure asessor-based eating disorder symptom severity over time.	Measured at baseline (discharge), at week 16 (end of treatment) and 6 month follow-up
Secondary	Changes in Body-Mass-Index (BMI)	Weight and height will be used to measure BMI over time.	Measured at baseline, week 16 and 6 month follow-up
Secondary	Changes in Eating Disorder Severity (self-report)	The Eating Disorder Examination Questionnaire (EDE-Q) will be used to measure self-reported eating disorder symptom severity over time.	Measured at baseline, week 16 and 6 month follow-up
Secondary	Changes in depressive symptoms	The Beck Depression Inventory-II (BDI-II) will be used to measure depressive symptoms over time.	Measured at baseline, week 16 and 6 month follow-up
Secondary	Changes in stages of change regarding specific eating disorder behaviors	The Stages of Change Questionnaire for Eating Disorders (SOCQ-ED) will be used to measure changes in stages of change regarding specific eating disorder behaviors over time.	Measured at baseline, week 16 and 6 month follow-up
Secondary	Changes in self-efficay	The General Self-Efficacy Scale (GSE) will be used to measure self-efficacy over time.	Measured at baseline, week 16 and 6 month follow-up
Secondary	Participant satisfaction with the app and the aftercare intervention	A self-developed questionnaire will be used to assess self-reported satisfaction with the app and the aftercare intervention.	Measured at week 16
Secondary	Additional outpatient and inpatient treatment after discharge	Number and length of outpatient or inpatient treatment (rehospitalization) since discharge will be assessed.	Measured at week 16 and 6 month follow-up
Secondary	Adherence to the smartphone-based aftercare intervention	Adherence will be measured via dichotomous outcome of drop-out (individuals will be considered as drop-out if they fail to login to the app at all for a period of 14 consecutive days. Adherence will be assessed through application usage data.	Measured from baseline to week 16
Secondary	Adherence to self-monitoring tasks	Frequency of self-monitoring entries will be tracked automatically through the program server	Measured from baseline to week 16
