Developing a measure of distress-promoting parent behaviors during infant vaccination: Assessing reliability and validity.

BACKGROUND

Infants rely on their parents' sensitive and contingent soothing to support their regulation from pain-related distress. However, despite being of potentially equal or greater import, there has been little focus on how to measure distress-promoting parent behaviors.

AIMS

The goal of this article was to develop and validate a measure of distress-promoting parent behaviors for acute painful procedures (e.g., vaccinations) that could be used by researchers and clinicians.

METHODS

Following initial generation of measure items, focused group discussions were held with vaccinating clinicians to understand the measure's face, content, and ecological validity. Archival video footage ( = 537 videos of infant-caregiver dyads during vaccination) was then coded using the measure of distress-promoting behaviors for 3 minutes post vaccine injection. Validity and reliability were examined using correlational analyses. Construct validity was assessed by convergent relationships with infant pain-related distress and divergent relationships were assessed with parent sensitivity and soothing-promoting behaviors.

RESULTS

The measure demonstrated both moderate to excellent interrater and test-retest reliability and convergent and divergent validity (absolute magnitude of 's = 0.30 to 0.46).

CONCLUSIONS

By demonstrating strong reliability and validity, this measure represents a promising new way to understand how caregivers interact with infants during painful procedures. Through focusing on distress promotion and using a format that may be coded both from video or in vivo, it is a feasible way to operationalize the impact of the caregiver on the infant's pain experience in both research and clinical settings.
