Description of intervention(s) / exposure
ERICA is an emotion regulation psychoeducation program that is delivered via a digital conversational agent, ERICA interacts with users via text and speech and users interact with ERICA via selecting options from pre-defined list. The program provides descriptive examples that aid in self reflection and practice activities to develop adaptive cognitive emotion regulation skills. The ERICA program has six different conversations/dialogues - the first dialogue explores techniques to assist with positive refocusing, the second focuses on the processes of planning and problem solving. The next two dialogues explore acceptance and reappraisal while the final two conversations focus on techniques to help put things in perspective. Each conversational dialogue takes approximately 10-15 minutes to work through (dependent upon answers selected) and each week, for three weeks, participants receive two emails (3 days apart) with a link to the next dialogue. Participants can access the links anytime over the four week intervention period (however they are encouraged to access each link on the day it is received). Participant interaction with ERICA will be captured via a system log which records login date, response options selected and the total length of time spent each session.

Comparator / control treatment
The comparator group is treatment as usual. This consists of regular contact with their personal injury claims consultant and prompting to talk to their GP if they express heightened psychological distress. The comparator group will be offered the intervention after the 4 week intervention period. They will be sent a webink to the ERICA program and will be advised that they can access at anytime for the next 4 weeks.

Statistical methods / analysis
Descriptive statistics will be used to describe the sample. Chi square tests and t-tests will be used to assess for differences between baseline and follow-up and one-way ANOVAs will be used to assess for group by time interactions. Intention to treat analyses will be used to examine differences between the intervention and control group on observed outcomes. A modified intention to treat analysis (mITT) will also be conducted with completers being defined as participants who log onto the ERICA program on at least one occasion.

Summary
Brief summary
This study aims to assess whether a digital conversational agent can be used to effectively deliver a low intensity emotion regulation intervention to people who have sustained a minor to moderate injury in a motor vehicle accident. This is a cohort of people who are often under stress. The intervention has been designed with input from clinical psychology and computer science. The intervention encourages people to reflect on the current way they manage negative emotions and provides information and examples of evidence based adaptive emotion regulation strategies that have been identified as being critical for effective coping. The emotion regulation strategies included in the program include positive refocusing, reappraisal, acceptance, planning and problem solving and putting things into perspective. It is anticipated that completing this intervention will assist participants to learn strategies to assist them to regulate emotions which will in turn increase their confidence that they can cope at this challenging time. It is also anticipated that the program will assist in reducing participant's reported levels of distress.
