Brief summary

We are conducting a trial to evaluate whether the removal of pathoanatomically-based biological information about knee osteoarthritis from a patient information pamphlet changes consumer management beliefs, compared to a standard information pamphlet that includes pathoanatomical information. The entire trial will be administered in one single online survey. Participants will initially complete screening questions within the survey to determine eligibility. Eligible participants will then complete baseline outcome measures before being randomly allocated to one of two groups, both of whom will then be asked to immediately read a digital information pamphlet about knee osteoarthritis on screen: i) Control group: the pamphlet will contain information about osteoarthritis including biological pathoanatomical information and language about osteoarthritis ii) Experimental group: the same pamphlet as the Control group, but with all pathoanatomical information and language relating to the structure of an osteoarthritis joint removed. All participants will complete outcome measures again, immediately after reading their allocated digital information pamphlet.

Interventions

Participants in the Experimental group will be asked to read an approx. 1-page digital information pamphlet about osteoarthritis that was created by the research team based on the content that is currently provided on international osteoarthritis consumer organisation websites. The content will be a similar to that contained in the Control group, but all pathoanatomical information and terminology will be removed. To develop this information sheet, the researchers reviewed the Control group inf

Participants in the Experimental group will be asked to read an approx. 1-page digital information pamphlet about osteoarthritis that was created by the research team based on the content that is currently provided on international osteoarthritis consumer organisation websites. The content will be a similar to that contained in the Control group, but all pathoanatomical information and terminology will be removed. To develop this information sheet, the researchers reviewed the Control group information pamphlet and deleted any words and/or sentences that related to joint anatomy or pathology, including words that described the joint structure, and words related to pathology like ‘damage’ and ‘wear and tear’. A diagram that depicted an image of a healthy joint compared to a joint affected by osteoarthritis was also removed. No new words, sentences or images were added to replace those that were removed. Participants in both groups will be asked to tick a box to confirm that they had read the information sheet and estimate how long they had spent reading it. The survey software (Qualtrics) will also measure how long each respondent spends on the page that has the information sheet.
