The objective of this study was to evaluate the agreement between the State Trait Anxiety Inventory (STAI) and other anxiety scales to determine whether these shorter to administer scales could replace the STAI.
This was a prospective cohort study on a convenience sample of children, aged 9 to 17 years, presenting to a pediatric emergency department. Patients were divided into 2 groups: preteens (PT) (aged 9-12 years) completed the pediatric STAI and teens (T) (aged 13-17 years) completed the adult STAI. Participants also completed a visual analog scale (0-100 mm), a Likert scale (1-5), and a short version of the STAI. Intraclass correlation (2-way mixed model, average measures) was used to evaluate agreement between the STAI and the other scales. A sample size of 100 patients per group was estimated as sufficient.
The median (interquartile range) STAI state anxiety scores were 33 (28.25-36.75) and 37.5 (32-44), in the PT (n = 100) and T (n = 100) groups, respectively. The median (interquartile range) STAI trait anxiety scores were 33.5 (28-38.75) and 36 (31-44), in the PT and T groups, respectively. Agreements between the STAI and the other scales were poor for all scales. At best, the intraclass correlation was 0.71 for the agreement between the STAI and the short version of the STAI.
There appears to be poor agreement between the STAI and the other scales designed to measure anxiety in children 9 to 17 years presenting to the pediatric emergency department.
本研究的目的是评估状态-特质焦虑量表（STAI）与其他焦虑量表之间的一致性，以确定这些更易于实施的量表是否可以替代STAI。
这是一项对9至17岁儿童便利样本进行的前瞻性队列研究，这些儿童前往儿科急诊科就诊。患者分为两组：青春期前儿童（PT）（9至12岁）完成儿童版STAI，青少年（T）（13至17岁）完成成人版STAI。参与者还完成了视觉模拟量表（0至100毫米）、李克特量表（1至5）以及STAI的简短版本。组内相关系数（双向混合模型，平均测量值）用于评估STAI与其他量表之间的一致性。估计每组100名患者的样本量就足够了。
PT组（n = 100）和T组（n = 100）的STAI状态焦虑得分中位数（四分位间距）分别为33（28.25 - 36.75）和37.5（32 - 44）。PT组和T组的STAI特质焦虑得分中位数（四分位间距）分别为33.5（28 - 38.75）和36（31 - 44）。STAI与所有其他量表之间的一致性都很差。在最好的情况下，STAI与STAI简短版本之间的组内相关系数为0.71。
对于前往儿科急诊科就诊的9至17岁儿童，STAI与其他旨在测量焦虑的量表之间的一致性似乎较差。
