Construct validity estimation for the African-American and Hispanic versions of the Oucher Scale.

This study examined the construct validity of the African-American and Hispanic versions of the Oucher Scale as measures of pain in 104 children ages 3 to 12 years old. Scores on the Oucher Scale, Analogue Chromatic Continuous Scale, and Child Medical Fear Scale were obtained after being administered concurrently on one occasion, either before or after surgery. Additionally, Oucher scores were obtained before and after analgesic administration. Significant correlations were found between the two pain intensity measures, while weak, nonsignificant relationships were revealed between the pain and fear measures. Preanalgesic scores were significantly higher than postanalgesic scores. These findings support the construct validity of the two new ethnic versions of the Oucher.
