In Brazil, there is no scale to assess parental catastrophizing about their child's pain. This study aimed to translate and cross-culturally adapt the Pain Catastrophizing Scale-Parents to the Brazilian Portuguese language, as well as to preliminarily evaluate its psychometric properties among parents/guardians of children with and without a toothache.
A cross-sectional study was conducted with 237 parents/other relatives of 237 children. Across-cultural adaptation of the scale into Brazilian Portuguese was carried out according to the universalistic approach. To assess the reliability and validity of the scale, parents/other relatives reported on the child's toothache and filled out the Brazilian versions of the Pain Catastrophizing Scale-Parents and the Dental Discomfort Questionnaire.
There was semantic equivalence with the original version after minor modifications. TheCronbach's alpha for the 13 items of the scale was 0.83, and the respective test-retest intraclass correlation coefficients ranged from 0.63 to 0.97. The scores obtained from the Pain Catastrophizing Scale-Parents and the Dental Discomfort Questionnaire had a low correlation (rho=0.25; p<0.001). Thetotal score of the Pain Catastrophizing Scale-Parents differed significantly (p<0.001) in children with a toothache at night (median: 3.0, 25-75 percentile: 25.0-35.5) compared to those who did not have a toothache at night (25.5; 20.0-31.0).
The Brazilian version of the Pain Catastrophizing Scale-Parents was acceptable in this preliminary evaluation and can be used in Brazilian clinical and research practice.
在巴西，尚无用于评估父母对其孩子疼痛灾难化认知的量表。本研究旨在将《疼痛灾难化量表 - 父母版》翻译成巴西葡萄牙语并进行跨文化调适，同时初步评估其在有或无牙痛儿童的父母/监护人中的心理测量学特性。
对237名儿童的237名父母/其他亲属进行了一项横断面研究。根据普遍主义方法，将该量表跨文化调适为巴西葡萄牙语版本。为评估该量表的信度和效度，父母/其他亲属报告孩子的牙痛情况，并填写巴西版的《疼痛灾难化量表 - 父母版》和《牙齿不适问卷》。
经过 minor modifications后与原始版本具有语义等效性。该量表13个条目的Cronbach's alpha系数为0.83，相应的重测组内相关系数范围为0.63至0.97。《疼痛灾难化量表 - 父母版》和《牙齿不适问卷》所得分数的相关性较低（rho = 0.25；p < 0.001）。与晚上无牙痛的儿童（25.5；20.0 - 31.0）相比，晚上有牙痛的儿童的《疼痛灾难化量表 - 父母版》总分差异显著（p < 0.001）（中位数：3.0，第25 - 75百分位数：25.0 - 35.5）。
《疼痛灾难化量表 - 父母版》的巴西版本在本次初步评估中是可接受的，可用于巴西的临床和研究实践。
