Influencing Factors for Physical Activity in People With Head and Neck Cancer
The goal of this qualitative study is to explore influencing factors for physical activity participation in people affected by an advanced head and neck cancer from the perspective of people affected and their significant others.

Individual interviews will be conducted with people affected by head and neck cancer and focus group interviews will be held with significant others of people being affected to answer the following research questions:

What capabilities and opportunities for physical activity participation do people with advanced head and neck cancer experience?
What motivates people with advanced head and neck cancer to be physically active?
How do significant others view capabilities, opportunities, and motivation for physical activity participation in people with head and neck cancer?

The interviews will be transcribed verbatim and analysed with a structuring content analysis approach.
