Aim:
The aim of this study was to investigate psychometric properties, reliability and validity, of Astrid Lindgren and Lund Children's Hospitals Pain and Stress Assessment Scale for Preterm and Sick Newborn Infants (ALPS-Neo), as a measure for procedural pain.
Methods:
This observational, prospective study with a repeated measures design, explored inter-rater reliability by two raters assessing 21 neonates during non-pain and pain events. Construct validity was explored, that is, ability to discriminate between non-pain and pain, and criterion validity by correlating ALPS-Neo with Premature Infant Pain Profile-Revised (PIPP-R) and Skin Conductance Algesimeter (SCA) in 54 neonates without ventilator support and sedation undergoing routine heel-stick procedure in a tertiary neonatal intensive care unit.
Results:
Mean gestational and assessment age of 54 infants was 33.8 weeks and 12.7 days respectively. Inter-rater reliability from baseline, skin wiping, heel-stick events for 21 infants demonstrated intraclass correlations with 95% confidence intervals (CI) of 0.49 (-0.27 to 0.79), 0.86 (0.65-0.94) and 0.73 (0.34-0.89) respectively. ALPS-Neo discriminated significantly between baseline, non-pain and heel-stick (mean differences from pain event -2.3 and -1.0 respectively) and correlated during heel-stick with PIPP-R (r = 0.56, 95% CI: 0.34-0.72), not with SCA.
Conclusion:
ALPS-Neo may be used as a measure for procedural pain.
