Design and objective: This paper describes the protocol for a three-arm, single-blind, parallel design randomized controlled trial (RCT) to investigate the perceived usability of Facebook to share information from an evidence-based arthritis self-management program with patients compared with email or an educational website after two weeks.
Study population: Three-hundred and twenty-seven arthritis health professionals (i.e., nurses or physical/occupational therapists) registered with their regulatory body in Canada, currently practicing clinically defined as spending a minimum of 50% of their time (working week) in direct arthritis patient care.
Interventions: The proposed RCT will include three information and communication technology (ICT) intervention groups: Facebook, email, and an educational website.
Outcome measures: The primary outcome will be perceived usefulness by health professionals of using the ICT intervention to share information with their patients according to the technology acceptance model 2 (TAM2) questionnaire at two weeks post-intervention. Secondary outcomes will include other usability domains of the TAM2 questionnaire (i.e., perceived ease of use, result demonstrability, output quality, job relevance, image, voluntariness, subjective norm, and intention to use) at two weeks, three months, and six months post-intervention.Analysis: An analysis of variance will be conducted to compare TAM2 questionnaire scores of the Facebook group with the email and educational website groups.
