Outcome variables

The two outcome variables were 1) previous acquisition of antibiotics other than from a physician in Sweden having issued a prescription and 2) likelihood of future acquisition of antibiotics other than from a physician in Sweden issuing a prescription. The survey question used to capture the first outcome variable was: “In the last five years, have you obtained antibiotics without a prescription from a physician in Sweden?”. The response alternatives were “Yes”, “No” and “Don’t remember”. The second outcome variable survey question was: “If you or a close relative were to become ill at some point during the next five years, how likely is it that you would obtain antibiotics without a prescription from a physician in Sweden (regardless of the cause)?”. The response alternatives were: “Very likely”, “Fairly likely”, “Fairly unlikely” and “Very unlikely”.
