The barriers to help-seeking scale19 validated within the original CAM remained an equivalent and wasn't a part of the present validation process. Expert review (N=7 experts) and cognitive interviews (N=17 members of the public) were wont to make sure that the
Lung CAM represented all facets of
carcinoma awareness (content validity) and to select the best items in terms of wording, terminology and comprehensiveness. This resulted in minor adjustments to the items to improve clarity.
