Effect of an E-learning Intervention on Knowledge, Attitudes and Beliefs of Healthcare Professionals Managing Low Back Pain.

The HC-PAIRS assesses attitudes and beliefs about functional expectations for patients with chronic LBP. It consists of 13 statements that must be rated on a seven-point Likert scale, ranging from 'totally disagree' to 'totally agree'. A high score on the HC-PAIRS reflects a belief with a strong relationship between pain and impairment. Psychometric properties of this questionnaire have been established.

The clinical vignette described a patient with non-specific LBP. This vignette was developed by Rainville. Participants were asked to assess the patient's ability to work, from 1 (full-time) to 5 (remain out of work) and gave their opinion on the appropriate level of activity, with choices graded from 1 (no limitations on activity) to 5 (limit all physical activity). If the score of the participant was between 1 and 2 it was considered guideline adherent. If the score was between 3 and 5 it was considered guidelines discordant.

The Back-PAQ questionnaire (10 items version) assesses attitudes and underlying beliefs about back pain on a 5-point Likert scale. The scoring of the answers ranges from -2 to +2. A negative score reflects beliefs that are unhelpful and vice-versa. All items were written in the second person to personalize the questionnaire. The purpose of this personalization is that HCPs or students present their own beliefs rather than projecting their beliefs onto people with LBP or presenting their beliefs about people with LBP.

The Neurophysiology of pain questionnaire (NPQ) assesses how an individual conceptualizes biological mechanisms underpinning pain. The NPQ includes 19 questions with three answer options (true; undecided; false). The scoring is 1 for a correct answer and 0 if the participant was wrong or undecided. This questionnaire was included to reflect recommendations of the guidelines for the management of LBP that encourages clinicians to explain and reassure the patient about their personal experience of pain.

4 clinical cases were developed by a multidisciplinary team of experts in the field (general practitioners, orthopedic surgeons, physiotherapists, and academics). Two cases described the symptoms of a patient with specific LBP and the two others described the symptoms of a patient with non-specific LBP. A specific and non-specific clinical case were presented at baseline and post-intervention assessment. Participants answered 3 open questions related to the clinical case: "In your opinion, what are the causes/contributing factors to the pain of this patient?"; "As an healthcare practitioners what would be your first approach to manage this patient?"; "Which advices would you give to this patient concerning physical activity". Coding of the answers in a matrix using keywords and themes will be used to analyse the orientation of the healthcare practitioners (guideline adherent or guideline discordant).

A Likert scale (1-7) will be used to examine the participants experiences regarding the content and quality of the intervention and the Technology acceptance. The questions of this survey are based on Cheng et al. 2012 and cover global system quality and technology acceptance of the e-learning. Higher score reflects a better experience with the e-learning intervention.

A purposive sample of participants agreeing to take part in a phone interview will be invited to an in-depth interview. We foresee to start with 10 HCPs of each group (experimental and traditional e-learning intervention) to provide depth and breadth of experiences and will continue until no new themes emerge (Bowen 2008). The principles of qualitative research will be used to explore how participants experienced the e-learning intervention and which impact had the e-learning on their clinical practice.
