There is no validated symptom scale for Swedish children with gastrointestinal disorders. Our aim was to validate the Swedish version of the Paediatric Quality of Life Inventory (PedsQL) gastrointestinal symptoms scale and symptoms module.
Families were recruited from two hospitals in Gothenburg, Sweden, from 1 March 2021 to 31 October 2022. The instruments were completed by 115 children with functional, congenital or organic acquired gastrointestinal disorders and 149 of their parents. These were the gastrointestinal symptoms scales, symptoms module and the 4.0 Generic core scale. Data were analysed for feasibility, construct validity and reliability, including internal consistency, re-test reliability and child-parent agreement.
Feasibility was good, with a failure to respond of ≤5%. Construct validity showed strong correlation in the PedsQL gastrointestinal symptoms module. The known-group validity agreed with the expectations associated with the disease characteristics (p < 0.05). Cronbach's alpha was 0.96, which indicated excellent internal reliability. The intraclass correlation coefficient for the child self-report and parent-proxy report was 0.74, which indicated good agreement.
The Swedish PedsQL Gastrointestinal Symptoms Scales, the symptoms module provided acceptable measurement properties and can be used to evaluate symptoms of gastrointestinal disorders and quality of life during clinical work or research projects.
目前尚无针对瑞典胃肠道疾病儿童的经过验证的症状量表。我们的目的是验证儿科生活质量量表（PedsQL）胃肠道症状量表和症状模块的瑞典版本。
本研究于 2021 年 3 月 1 日至 2022 年 10 月 31 日期间在瑞典哥德堡的两家医院招募了患儿及其家长。共纳入了 115 例功能性、先天性或后天获得性胃肠道疾病患儿及其 149 名家长，完成了胃肠道症状量表、症状模块和 4.0 通用核心量表的评估。分析了量表的可行性、结构效度和信度，包括内部一致性、重测信度和患儿-家长一致性。
可行性良好，应答失败率≤5%。PedsQL 胃肠道症状模块的结构效度显示出较强的相关性。已知组间的区分效度与疾病特征相符（p<0.05）。Cronbach's alpha 为 0.96，表明内部信度极好。患儿自评和家长报告的组内相关系数为 0.74，表明一致性良好。
瑞典版 PedsQL 胃肠道症状量表及其症状模块具有可接受的测量特性，可用于评估胃肠道疾病患儿的症状和生活质量，可用于临床工作或研究项目中。
