Plain English Summary
Background and study aims
Lower back pain is a common problem, which affects most people at some point in their lives. Many people who experience LBP will recover quickly with no significant impact to their lives, but for some people the pain turns into a long term condition which can affect their ability to work. When a sufferer experiences episodes which last for at least three months, it is known as chronic lower back pain (CLBP). People who suffer from CLBP are prone to repeated episodes (recurrent back pain), which can have a big impact on their family, social and working lives. In some cases, CLBP can lead to a long-term pain-related disability, where a person is in so much pain that it is preventing them from behaving normally. For many years, the “flags approach” has been used to judge how likely a person is to develop a long-term pain-related disability from their CLBP. This approach works by identifying factors which could get in the way of a person’s recovery. These factors are represented by coloured flags and can be medical (red flags), psychological (yellow flags), social (blue flags) or work-related (black flags). By identifying whether a patient has any of these “flags”, a doctor is able to judge the most appropriate action to take. The aim of this study is to find out whether an online educational video based on the flags approach can improve judgement in CLBP cases.
Who can participate?
Current GP trainees or third, fourth or fifth year medical students.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group (intervention group) are shown an 18 minute video, teaching them about the flags approach and how best to use it. Half way through this video, participants complete an exercise using a fictional case study in which they can practice these skills. Those in the second group are put on a waiting list. Immediately before and after the first group watch the video, both groups are given a number of fictional CLBP case studies. They are then asked to assess each case study and judge the future risk of pain-related disability for each of the cases. Their performance in this task is judged by the investigators in terms of accuracy, weighting and speed. After the study is completed, participants in the second group are given the opportunity to view the e-learning video.
What are the possible benefits and risks of participating?
Participants may gain better insight into the best ways to handle cases of CLBP, and so are better able to judge the more appropriate course of action in future. There are no risks of taking part in the study.

Evaluating the effectiveness of a biopsychosocial e-learning intervention on medical students’ and GP trainees’ clinical judgment-making regarding future risk of disability in patients with CLBP: Study protocol for a randomised controlled trial
Those who receive a training intervention will out-perform controls on judgment accuracy regarding future risk of disability and biopsychosocial model (flags approach) knowledge from pre-to-post-testing; will demonstrate attitudes and beliefs towards pain more consistent with the biopsychosocial model than controls from pre-to-post-testing; and will distribute the weight of their judgments more evenly (i.e. across biopsychosocial factors) than controls from pre-to-post-testing.

Chronic Lower Back Pain
Participants are randomised to the intervention or waiting list control group to using a web-based password secured and encrypted data management system to ensure that the groups are balanced.
Intervention group: Participants in the intervention group will complete the e-learning Flags Approach to Clinical Judgment educational intervention, which involves watching an 18-minute video, with an active learning exercise included in the middle, developed to teach the fundamentals of the bio-psychosocial model via the Flags Approach.
Control group: Participants will wait in an adjacent room where they will be provided non-medically-related magazines to read at their leisure.
Both groups will complete the full battery of assessments immediately before (time 1) and after (time 2) the intervention. Controls are wait-listed and will be provided an opportunity to view the intervention video following completion of the research.
Primary outcome measure
1. Judgement is measured using online tools according to responses to fictional case studies after the intervention
2. Judgment speed (response time) is measured in milliseconds as the length of time from the moment a case appeared on screen until a response (i.e. identifying, from 1-10, future risk of disability) is clicked via the mouse
Secondary outcome measures
1. Flags Approach knowledge is assessed using a multiple choice question test immediately before and after the intervention
2. Biomedical/biopsychosocial approach to chronic lower back pain is measured using the pain attitudes & beliefs scale (PABS) immediately before and after the intervention
3. Empathy is measured using the interpersonal reactivity index (IRI) immediately before and after the intervention
