Item Number of caregivers who did not find the item relevant (or other rationale for deletion) Example quote to support deletion
How much has caregiving caused you health problems? 8/18 (plus caregivers found it difficult to attribute health problems specifically to caregiving) Not at all. I haven’t had any problems related - not that I know of” (04–08)
How much have you felt overly relied upon by the person you care for? 6/18 (plus conceptual equivalence to the item ‘have you felt the person you care for asks for too much’ considered easier to understand) I would say we’ve been through this before. You know the rules” (03–08)
How much has caregiving made you feel resentful? 12/18 (plus 3/18 caregivers found it difficult to understand) “Not at all. I don’t resent that, because my grandfather took care of me as a kid” (04–03)
How much has caregiving made you feel depressed? 7/18 (plus 4/9 caregivers from set 1 considered ‘depression’ too severe or clinical a term; 15/18 caregivers found the item ‘how much has caregiving made you feel sad’ more relevant “I don’t think both of those are necessary because it’s kind of the same. I prefer sad just because depressed just sounds…a little harsher, I guess” (04–04)
How much has caregiving made you feel helpless? 11/18 (plus 12/18 caregivers considered the item ‘has caregiving made you feel overwhelmed’ more relevant) But I can do it, help her with things, so [it isn’t relevant]” (03–08)
How much have you been unable to do the things you want to do? 7/18 (plus 15/18 caregivers considered the item ‘have you felt like you have no time for yourself’ more relevant) “There’s nothing I really want to do right now.” (03–04)
How much has caregiving limited your travelling? 8/18 (plus conceptual equivalence with the items ‘has caregiving caused you to change/avoid making plans’ and ‘have you felt you cannot be away from the person you care for’ considered more relevant.) “Because I drive, I do what I want to do - as far as traveling.” (03–05)
