在快节奏的医疗环境中，确定最有效和理论上最合适的方法来评估患者的焦虑可能有利于临床目的和研究。本研究的目的是检查两个先前发表的状态-特质焦虑量表（STAI）的状态形式的六项版本的可靠性和有效性，并确定最适合用于正常或异常新生儿筛查婴儿的父母样本的版本。在本研究中，进行验证性因素分析，以评估适合的两个六项形式与STAI数据收集在三个时间点，从288父母的150名婴儿。父母的研究组基于婴儿新生儿筛查和随后的诊断测试，包括囊性纤维化（CF; n = 26）、先天性甲状腺功能减退（CH; n = 39）、CF携带者（CF-C; n = 45）和健康婴儿（H; n = 40）。结果显示，包含STAI状态表第1、3、6、15、16和17项的版本在所有三个时间点上都是更好的拟合模型，并且其内部一致性优于包含第5、9、10、12、17和20项的版本。这两个简短的形式是高度相关的20项STAI评分，所有内部一致性的信度都大于0.90。结论是，包含状态焦虑量表第1、3、6、15、16和17项的版本对于本研究样本是可靠和有效的工具。
Identifying the most efficient and theoretically appropriate methods to assess patient anxiety in fast-paced medical environments may be beneficial for clinical purposes as well as for research. The purpose of this study was to examine the reliability and validity of two previously published six-item versions of the State form of the State-Trait Anxiety Inventory (STAI) and to identify the version that would be most appropriate to use with a sample of parents who had infants with normal or abnormal newborn screens. In the current study, confirmatory factor analyses were conducted to evaluate the fit of the two six-item forms with STAI data collected at three time points from 288 parents of 150 infants. Study groups of parents were based upon infant newborn screens and subsequent diagnostic testing to include cystic fibrosis (CF; n = 26), congenital hypothyroidism (CH; n = 39, CF Carriers (CF-C; n = 45), and healthy infants (H; n = 40). The results showed the version containing items 1, 3, 6, 15, 16, and 17 of the State form of the STAI to be a better fitting model across all three time points, and it had better internal consistency than the version containing items 5, 9, 10, 12, 17, and 20. Both short forms were highly correlated with the 20-item STAI score, and all internal consistency reliabilities were greater than .90. It was concluded that the version containing item 1, 3, 6, 15, 16, and 17 of the State Anxiety scale was a reliable and valid instrument for this study sample.
