Development of a new computer method to assess children's pain.

OBJECTIVE

The primary objective of this study was to determine initial psychometric properties and feasibility of a new Computer Face Scale for measuring pediatric pain. Drawbacks to current measurement tools include a lack of continuous variables, suboptimal mode of implementation, and difficulty interpreting results. A computer method of pediatric pain measurement is presented that addresses these problems. Basic psychometric properties, feasibility, and children's preference when compared with Wong-Baker Faces Scale were determined.

METHODS

Fifty-four hospitalized, pediatric inpatients were tested using both the Computer Face Scale and the Wong-Baker Faces Scale. An additional 30 children (not hospitalized) were tested using only the Computer Face Scale.

RESULTS

Both hospitalized and nonhospitalized children between the ages of 3 and 17 years of age are able to use the Computer Face Scale to express relative amounts of pain/hurt and happiness. The Computer Face Scale shows acceptable psychometric properties and is preferred by most children.

CONCLUSIONS

The Computer Face Scale offers advantages over traditional pediatric pain measurement tools. The opportunity for real time review, electronic and time-stamped recording, electronic display, and temporal comparisons of reports affords the potential for improvement in pediatric pain assessment and treatment.
