ScottTriGuy,
That is a good question. That question is part of a standardized instrument so the questions about motivation is about whether you want to do not. Not whether the outcome would be bad a result of doing the activity. Going back to you example, I never want to shovel snow even if it didn't have a negative impact on me, so I would answer no the
Just because something is a "standardised" instrument doesn't mean it is reasonable or appropriate.
Zero PROMs for example have been properly tested for acceptability, understandability, relevance/appropriateness to patients and so on. The fact is the construct validity of such measures have not actually been tested in a reasonable manner in this group of patients.

Reliability coeficients and Cronbach's Alpha are insufficient to determine validity because the correlations can be biased by a wide variety of factors - particularly common biases in questionnaire answering behaviour (participation bias, social desirability bias etc), but also methodological and design biases.
Likewise, most if not all of these items have not been tested for whether the scoring methods are reasonable in this patient group (many questionnaires have questions that are poorly designed which would technically require non-linear or even disordered scoring in subsets of patients if these scores were to reflect reality). Or likewise, whether each set of items actually scale.
This is why many patients do not like participating in such surveys and why you will necessarily get biased / low quality results that are difficult to generalise. This is a widespread problem across the field of health psychology and related fields and will continue until new/younger/innovative researchers realise the methodologies commonly used in the field are crap and choose to fix the mess.
