Abstract
OBJECTIVE: to validate a Standard Operating Procedure on the intramuscular vaccine administration technique in adults using high frequency vibration associated with cryotherapy. METHODS: a literature review on intramuscular vaccination practice using a vibration device associated with cryotherapy. Then, a form was created to validate the instrument, detailing the items that were assessed by judges following recommendations in the literature. Judges' answers were assessed using the Content Validity Index, with items whose index was greater than or equal to 0.80 being validated. RESULTS: twenty-five nurses participated in validity, identifying judges' opinion regarding item relevance, clarity and accuracy. Judges validated the instrument, according to the values that remained between 0.88 and 1.0. CONCLUSIONS: the instrument developed and validated is a tool capable of guaranteeing safety and standardizing immunization practice in vaccine rooms.
