Content validity of the Scale for Assessing the Risk of Phlebitis in Hospitalized Adults.

OBJECTIVES

to construct and validate the content of a scale for assessing the risk of phlebitis in hospitalized adult patients using peripheral intravenous therapy.

METHODS

a methodological study, developed according to DeVellis, in four stages, from January to July 2024. For content validity analysis, Content Validity Ratio (CVR) was calculated, including items that reached a critical point of 0.667 (first round) and 0.538 (second round).

RESULTS

the scale contained 95 items, including those with a value above the critical point of the CVR. Items that received suggestions from experts and also presented a CVR above the critical point were redacted and retained. A scale containing 28 items, distributed across three dimensions, was constructed.

CONCLUSIONS

the scale showed good measures of content validity and response process. Since it was assessed as easy to understand, it became a useful tool for use in the care of patients undergoing peripheral intravenous catheter therapy.
