Vulnerability to physical inactivity: evidence of content validity and response processes - Revista Brasileira de Enfermagem
Revista Brasileira de Enfermagem. 11-13-2023;76(Suppl 2):e20220563
To analyze content validity evidence and response processes of a bank of items for measuring vulnerability to physical inactivity in adults.
Methodological study, with 13 specialists and 46 representatives of the target population. The Content Validity Index (CVI) and binomial test were calculated; data obtained through validity based on response processes were collected through interviews.
Of the 105 constructed items, 16 were excluded (CVI<0.78); 89 items showed agreement <80% in the psychometric criteria, being modified. Of the 101 items that remained (CVI>0.78), 34 were changed and 4 were deleted after evaluating the evidence of response processes. In the end, 97 items remained, with a global CVI of 0.92, organized into two dimensions: Subject (CVI=0.91) and Social (CVI=0.94).
The items presented adequate parameters and evidence of validity; and can subsidize the construction of instruments that consider the subject’s and social vulnerability in understanding physical inactivity.
