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.
