Exploring Tailored Virtual Emotion Regulation Approaches for Individuals with Emotional Eating 157 6 demographic questions, the DEBQ-E, the I-PANAS-SF and the DERS-SF. Based on their scores on the awareness, impulse and strategies subscale of the DERS-SF, participants were assigned to one of the three tailored exercises, as described in paragraph Tailored exercises on the next page. Assignment of participants Participants in the current study were assigned to one of three groups based on their scores on the three DERS-SF subscales (i.e., awareness, impulse, and strategies) at baseline (T0). The group receiving the body scan exercise was called group A. The group that received the opposite action exercise was called group B and the group that received the positive reframing exercise was called group C. Group A | body scan Participants who scored high on the awareness subscale (score ≥ 9; that is, the respondent scored 3 or higher on all 3 items of the subscale), having difficulties with being aware of or paying attention to emotional responses, were assigned to a group with participants that received the body scan exercise. Group B | opposite action Participants who scored low on the awareness subscale (score < 9) AND high on the impulse subscale (score ≥ 9) were assigned to a group with participants that received the opposite action exercise. Group C | positive reframing Lastly, participants who scored low on both the awareness AND impulse subscales (scores < 9) AND high on the strategies subscale (score ≥ 9) OR scored low on all subscales (all scores < 9) were assigned to a group with participants that received the positive reframing exercise. Course of the study Participants were asked to practice (+/- 15 minutes) every other day with the assigned exercise for two weeks. The duration of the current study protocol is in line with the typical duration of daily diary studies; one to four weeks [54]. Participants were provided access to the exercise within the online survey environment through email on alternate days. The exercises were accompanied by instructions. In addition to baselinemeasurements (T0) of the I-PANAS-SF and DERS-SF, measurements were conducted after one week at mid-intervention (T1), and after two weeks at postintervention (T2). The post-intervention questionnaire also included five open questions about their experience with the assigned exercise (Methods > Materials > Qualitative data).
