Objective: Inadequate assessment of pain in premature infants is a per
sistent clinical problem. The objective of this research was to develo
p and validate a measure for assessing pain in premature infants that
could be used by both clinicians and researchers. Design: The Prematur
e Infant Pain Profile (PIPP) was developed and validated using a prosp
ective and retrospective design. Indicators of pain were identified fr
om clinical experts and the literature. Indicators were retrospectivel
y tested using four existing data sets. Patients and Settings: Infants
of varying gestational ages undergoing different painful procedures f
rom three different settings were utilized to develop and validate the
measure. Methods and Results: The largest data set (n = 124) was used
to develop the PIPP. The development process included determining the
factor structure of the data, developing indicators and indicator sca
les and establishing internal consistency. The remaining three data se
ts were utilized to establish beginning construct validity. Conclusion
s: The PIPP is a newly developed pain assessment measure for premature
infants with beginning content and construct validity. The practicali
ty and feasibility for using the PIPP in clinical practice will be det
ermined in prospective research in the clinical setting.
