Cognitive behavioural therapy (CBT) is the most empirically supported and researched treatment for eating disorders. A central component of CBT for eating disorders is self-monitoring which involves patients keeping a paper food record of their meals and associated thoughts, feelings, and behaviours and receiving feedback from a clinician to help target dysfunctional cognitions and behaviours. Given the issues associated with paper journals such as non-compliance, feelings of shame when used in public, and delayed feedback, researchers have developed an evidence-based smartphone application (Recovery Record) for eating disorder self-monitoring that links patients with their clinicians and offers additional features designed to enhance treatment.
The current pilot randomised controlled trial (RCT) seeks to evaluate this smartphone application in a clinical setting alongside standard eating disorder outpatient treatment. Patients will be recruited from the Nova Scotia Health Authority Eating Disorder Outpatient Program and randomised to receive either standard treatment or standard treatment with the app (instead of the paper food record). The efficacy and acceptability of both treatments will be assessed and compared. Coping skill use and self-efficacy among patients will also be examined given the skill building focus of treatment and in-app capabilities to deliver real-time coping skill suggestions to patients.
This pilot study will be the first to examine the efficacy and acceptability of a smartphone application in eating disorder clinical treatment and if successful, should provide preliminary support for the use of smartphone applications over traditional paper food journals as a self-monitoring tool for augmenting specialty eating disorder clinical treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Treatment as Usual | Active Comparator | Patients will receive standard outpatient treatment that consists of group psychotherapy, skills training, self-monitoring, nutritional counselling, and meal support. |
|
| Treatment with Smartphone App | Experimental | Patients will receive the same standard outpatient treatment but will use the smartphone application instead of the paper food record. Patients in this group will receive daily feedback through the app, as opposed to weekly, but will still attend the weekly nutritional counselling group. |

| Name | Type | Description | Arm Group Labels | Other Names |

| Standard Outpatient Treatment | Behavioral | Standard treatment offered by the Nova Scotia Health Authority Eating Disorder Outpatient Program varies in intensity but involves therapy groups (e.g., goal setting and skill building groups), individual contact, and meal experiences. Minimal participation in the program consists of a weekly nutritional counselling group (Nutri-Logical) and one supervised meal a week. In the nutritional counselling group, patients keep a food journal (self-monitor), set eating goals, receive feedback from a psychologist and dietitian, and share experiences with the group. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in eating disorder severity as assessed by the Eating Disorder Examination Questionnaire (EDE-Q) | A self-report scale that assesses the severity of 4 areas of eating disorder pathology: Eating Concern, Weight Concern, Dietary Restraint, and Shape Concern. Overall eating disorder severity is also assessed. | Pre-treatment, 2 months, post-treatment (up to 8 months after pre-treatment), 3-month follow-up |
| Measure | Description | Time Frame |
|---|---|---|
| Change in coping skill use as assessed by the Cognitive Behavioral Therapy Skills Questionnaire (CBTSQ) | A self-report measure that assesses the use of CBT-taught skills. | Pre-treatment, 2 months, post-treatment (up to 8 months after pre-treatment), 3-month follow-up |
| Change in coping skill use as assessed by the Dialectical Behavior Therapy Ways of Coping Checklist (DBT-WCCL) |
| Measure | Description | Time Frame |
|---|---|---|
| Diagnoses validated by the Eating Disorder Diagnostic Scale (EDDS) | A self-report diagnostic measure that will be used to validate clinical diagnoses (as determined by team psychiatrist or clinical psychologist). | Pre-treatment |

| Smartphone App | Behavioral | The smartphone app is a mobile eating disorder self-monitoring tool that incorporates discrete reminders, positive feedback, social support, summative feedback, coping skill suggestions, and linking patients with their treating clinicians (psychologist and dietician). The app is CBT-based and was designed as an alternative to paper food records for use in clinical treatment. |
