Not all of the examples provided to illustrate the questions were performed or the activities performed were not among the examples.

AQuAA and PASE.

"I climb the stairs, 7 times a day. I do not clean, but I do carry light loads. I do not know how to fill this out, so I will skip this." (61 year old woman with non-Hodgkin's lymphoma).

Different perception of intensity level.

The intensity level at which a certain activity was classified did not match the perceived intensity level.

AQuAA and PASE.

"Here it says that making the bed is a light household chore, but because I cannot do it, I find it a strenuous activity." (47 year old woman with non-Hodgkin's lymphoma)

"Jogging is classified as a vigorous intensity sport, however for me it is not more than a moderate intensity activity." (26 year old woman with non-Hodgkin's lymphoma)

Recall of frequency and duration.

Recalling the time spent on PA, other than sports and exercise, was challenging.

AQuAA.

"I do not constantly keep track of the time while cleaning the house." (46 year old woman with cervical cancer)

Calculating the amount of time spent on activities.

Whether the duration of physical activities should be divided across the actual number of days the activities were performed (e.g. 2 days) or across the whole week (i.e. 7 days).

AQuAA and PASE.

"If I perform an activity 2 days a week for 2 hours each day, to calculate the amount per week should I divide the total hours by 2 or 7 days?" (59 year old woman with breast cancer)
