Objective: This study investigated the associations between caregiver verbal reassurance and infant pain-related distress during immunization over the first year of life. The relationships between verbal reassurance and caregiver emotional availability (EA) were also examined. Finally, EA was investigated as a moderator of the relationship between verbal reassurance and infant pain.
Methods: A cross-sectional analysis was conducted with 606 infants (and their parents) at 4 different ages (n = 376 at 2 months, n = 455 at 4 months, n = 484 at 6 months, and n = 407 at 12 months).
Results: Verbal reassurance was positively associated with infant distress across all four ages. EA was only negatively related to verbal reassurance at 12 months of age. EA was not a significant moderator at any age.
Conclusion: Findings demonstrate consistent but small relationships between verbal reassurance and infant pain over the first year of life.
