The sample size of 200 participants is based on a previous study of illnesses labeled ‘urate crystal arthritis’ or gout’, this sample size allowed detection of an at least 2 point difference in the Brief Illness Perception Questionnaire items with power of 0.9 and alpha of 0.05. No adjustment will be made for multiple testing.
Demographic differences between the two groups will be explored with independent sample t tests and chi-square tests. The primary endpoint will be illness perception as measured by the Brief Illness Perception Questionnaire. Differences between the groups in illness perceptions, causes and management strategies will be tested with independent sample t tests.

Summary
Brief summary
Television and film can affect how we understand illness. Gout is a common form of arthritis. Historically, gout has been viewed as related to overindulgence. Gout is frequently described as related to overindulgence of food and beverages in popular media such as newspapers and television. We hypothesise that viewing a television episode depicting gout as a humorous disease of overindulgence will lead to negative perceptions about gout and its management.
