Evaluation of a brief parent intervention teaching coping-promoting behavior for the infant immunization context: a randomized controlled trial.

This study was designed to investigate whether a brief intervention encouraging parental coping-promoting talk within the treatment room would have beneficial effects on infant pain responses to an immunization injection. Infant-parent dyads were recruited from a 6-month immunization clinic and randomized to an intervention group (n = 25) or standard care control group (n = 25). Parents in the intervention group received an information sheet describing adult verbalizations associated with better pain outcomes for infants.

Factors associated with infant pain response following an immunization injection.

Objectives: Specific potential determinants of infant pain response were assessed in the context of a 4- or 6-month immunization injection. The distal influences of gender, gestational and current age, temperament, and early nociceptive stimuli were considered, as well as the proximal influences of parental and nurse coping-promoting statements within the treatment room.

Study Design: An observational study design was used.
