Willingness as response to “Think about what you might do in the next year. If anal cancer screening were offered to you, would you get an exam where a doctor or nurse inserts a swab (like a long, thin Q-tip) into your anus (“anal Pap test”)”: “Very likely”, “Likely” and combined “Undecided”, “Don’t know”, “Unlikely” and “Very unlikely” as “Unlikely/Undecided”.
