Infant Distress During Immunization: A Multimethod Assessment

The purpose of this study was to comprehensively describe infant procedural distress and pain across assessment modalities, and to compare similarities and differences across measures. A multimethod assessment of distress was conducted to investigate infants (N = 37) undergoing routine immunizations. Measures of infant distress included Parent report, nurse report, infant heart rate, and an observational measure of infant distress. Parents rated their infant's distress and pain significantly higher than did nurses. Observational and physiological ratings of infant distress were found to vary significantly by phase, and there were no correlations between adult ratings of pain and distress and physiological ratings. Findings suggest that infant procedural distress can be assessed in a number of manners. The discordance between these measures emphasizes the need for multimethod assessment of pediatric procedural distress in both research and clinical settings. Given the differences between parent and nurse ratings, clinicians should be aware that different assessment methods might lead to different conclusions about infant procedural distress.
