Content Validity of the Spanish Adaptation of the Premature Infant Pain Profile Revised.

BACKGROUND

To the best of our knowledge, there are no validated neonatal pain assessment scales in Spanish. Given the need for such a scale, a study was undertaken to adapt and validate the Premature Infant Pain Profile-Revised (PIPP-R) scale. After translation and back-translation, content validity was addressed, a crucial phase in validation studies, in which researchers examine whether the items that make up the scale represent the content that the scale is intended to assess.

AIMS: The aim was to provide evidence for the content validity of the Spanish adaptation of the PIPP-R scale.

METHOD: The study used the Delphi technique with 10 experts. Data collection was anonymous and was conducted through an online platform. It was an ad hoc survey consisting of four questions, with a five-point Likert scale for each item on the scale and for the instruction table. An item-content validity index (I-CVI) and a scale-content validity index (S-CVI) were calculated for the analysis.

RESULTS

After two rounds of the survey, all items exceeded an I-CVI of 0.9. The S-CVI value was 0.98 (±0.03) for the scale, and 1 for its instruction table. The kappa index yielded values indicating an excellent degree of agreement.

CONCLUSIONS

The Spanish version of the PIPP-R obtained a high degree of content validity according to the expert group and the Delphi technique.
