Visual training program for body dysmorphic disorder: A novel intervention trial
Up to 20 participants diagnosed with body dysmorphic disorder (BDD) will be recruited to participate in a visual training program. The visual training program will involve three phases presented in a bottom up sequence, consisting of 1) basic visual processing, 2) face specific visual processing, and 3) self-perception. Phases 1 and 2 will be administered using computer tasks from Posit Science (Brain HQ), and phase 3 involves 'perceptual mirror retraining' activities drawn from the Cognitive-Behavioral Therapy for Body Dysmorphic Disorder manual (Phillips, Wilhelm & Steketee, 2012).
Phase 1 will be delivered during weeks 1-4 using the Posit Science computer training module. This phase will be administered in a one-on-one face-to-face consultation between the therapist and participant, where the therapist will provide instructions and answer any questions. Adherence will be monitored using feedback from posit science.
Phase 2 will be delivered during weeks 5-8 using the Posit Science computer training module. This phase will be administered in a one-on-one face-to-face consultation between the therapist and participant, where the therapist will provide instructions and answer any questions. Adherence will be monitored using feedback from posit science.
Phase 3 will be delivered during weeks 9 and 10 using perceptual mirror retraining principles. This phase will be administered in a one-on-one face-to-face consultation between the therapist and participant, where the therapist will instruct, and guide the participant through the exercise and answer any questions.
This visual training program will be presented over a series of 10 weekly sessions, with each session running for one to two hours, resulting in a total of 16.8 hours in line with recommendations from Posit Science. Participants will complete a comprehensive pre- and post-assessment, including a range of self-report questionnaires, clinical interview measures, and a full eye-tracking battery. Between each phase, participants will also complete a brief assessment to track for any change throughout the program, including a brief symptom severity measure and eye tracking task. This program will be conducted by a provisional psychologist who has received specialised training in BDD in both clinical and research-specific contexts. The provisional psychologist will be blind to all assessment results. This training program will be administered face-to-face at Swinburne University of Technology, Melbourne, Australia.

Primary outcome [3] 304810 0
Change in diagnostic criteria met as qualified by the Mini International Neuropsychiatric Interview (MINI), including the Body Dysmorphic Disorder Module (BDDM)

Secondary outcome [1] 343262 0
Change in 'Dysmorphic concern questionnaire' (DCQ) scores
Timepoint [1] 343262 0
Baseline (prior to commencement of treatment), weeks 4, 8, 10, and 7 days post intervention
Secondary outcome [2] 343263 0
Change in the 'memory-guided' task assessed using an eye tracking machine. In this task, participants will be asked to fixate on a cross in the centre of the screen whilst another stimulus is presented in the periphery. The stimulus will disappear after a short period and then the participant will be required to look at (make a saccade towards) where they recall the stimulus in the periphery to have appeared. Performance on this task is assessed by inhibitory error rate and eye movement parameters.

Efficacy
Statistical methods / analysis
Due to the innovative and novel aspects of this visual training program to be used in BDD, a single-group open label trial will be conducted. As this will be an exploratory study of the effectiveness and feasibility of the visual training program, sample size calculations were not conducted.
Repeated measures analysis of variance (ANOVA) will be conducted to compare performance on the measures used within the change tracking assessments, including the brief eye tracking measure and the DCQ. This will assess the impact each phase has upon last, by examining the participants’ eye movements and symptom severity. A one-way analysis of variance will also be performed to compare results from the pre- and post-assessments (clinical interview, self-report questionnaires and battery of eye tracking tasks), to determine the overall impact of the 10-week visual training program.
