Disquiet and misgiving in equal measure (5)

I believe the answer is:

qualm

I'm a little stuck... Click here to teach me more about this clue!

'disquiet and misgiving' is the definition.
I can't judge whether this defines the answer.

'in equal measure' is the wordplay.
'in' indicates the answer is hidden within the clue.
'QUALM' is hidden in the letters of 'equal measure'.

Can you help me to learn more?

(Other definitions for qualm that I've seen before include "Feeling of doubt" , "Uneasiness, doubt" , "Scruple" , "Uneasy feeling" , "Apprehension" .)

I've seen this clue in The Globe and Mail.
