To evaluate the validity of the Color Analog Scale (CAS) for assessing pain intensity in a Catalan-speaking pediatric population.
We compared children's CAS pain intensity ratings with their scores on the Catalan version of the Faces Pain Scale-Revised (FPS-R). We also compared the CAS to ratings of affective experience of pain evaluated with the Facial Affective Scale (FAS).
A total of 124 Catalan-speaking children aged 7 to 15 years admitted to the pediatric wards of 3 university hospitals participated in the study. The results supported the construct and criterion validity of the CAS in the Catalan population. Correlation between CAS and FPS-R scores was high and significant (r=0.87; P <.001). Similarly, pain intensity scores correlated significantly with emotional discomfort recorded with the FAS (r = 0.34; P < .001). Most of the children, regardless of sex or age, reported a preference for the FPS-R over the CAS.
The results of the present study provide preliminary evidence of the convergent, discriminant, and criterion validity of the CAS in this setting. The CAS appears to be valid for measuring pain intensity in Catalan-speaking children and adolescents between the ages of 7 and 15 years.
评估颜色模拟量表（CAS）在加泰罗尼亚语儿童群体中评估疼痛强度的有效性。
我们将儿童的CAS疼痛强度评分与其在加泰罗尼亚语版面部疼痛量表修订版（FPS-R）上的得分进行比较。我们还将CAS与通过面部情感量表（FAS）评估的疼痛情感体验评分进行比较。
共有124名年龄在7至15岁、讲加泰罗尼亚语且入住3家大学医院儿科病房的儿童参与了该研究。结果支持了CAS在加泰罗尼亚人群中的结构效度和效标效度。CAS与FPS-R得分之间的相关性高且显著（r = 0.87；P <.001）。同样，疼痛强度得分与通过FAS记录的情绪不适显著相关（r = 0.34；P <.001）。大多数儿童，无论性别或年龄，都表示更喜欢FPS-R而非CAS。
本研究结果为CAS在该环境中的收敛效度、区分效度和效标效度提供了初步证据。CAS似乎可有效测量7至15岁讲加泰罗尼亚语的儿童和青少年的疼痛强度。
