Introduction:
Choosing Wisely, an international effort to reduce low value care worldwide, considers communication between clinicians and patients during routine clinical encounters a key mechanism for change. In Australia, Choosing Wisely has developed a 5 Questions resource to facilitate better conversations. The primary aim of this study is to evaluate the impact of the Choosing Wisely Australia 5 Questions resource and a video designed to prepare patients for question-asking and participation in shared decision-making on (a) self-efficacy to ask questions and participate in shared decision-making, (b) intention to participate in shared decision-making and (c) a range of secondary outcomes. The secondary aim of this study is to determine whether participants' health literacy modifies the effects of the interventions.
Methods And Analysis:
We will use 2×2×2 between-subjects factorial design (preparation video: yes, no × Choosing Wisely 5 Questions resource: yes, no × health literacy: adequate, inadequate). Participants will be recruited by an online market research company, presented with a hypothetical non-specific low back pain scenario, and randomised to study groups stratified by health literacy. Quantitative primary and secondary outcome data will be analysed as intention-to-treat using appropriate regression models (ie, linear regression for continuous outcomes, logistic regression for dichotomous categorical outcomes).
Ethics And Dissemination:
Ethical approval for this study was obtained from the University of Sydney Human Research Ethics Committee (protocol number: 2018/965). The results from this work will be disseminated through peer-reviewed international journals, conferences and updates with collaborating public health bodies. Resources developed for this study will be made available to patients and clinicians following trial completion.
Trial Registration Number:
This trial has been registered with the Australia New Zealand Clinical Trials Registry (trial number: 376477) and the stage is Pre-results.

First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
