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 items 1, 3, 6, 15, 16, and 17 of the State Anxiety scale was a reliable and valid instrument for this study sample.
确定在快节奏医疗环境中评估患者焦虑的最有效且理论上最合适的方法，可能对临床及研究均有益处。本研究的目的是检验先前发表的状态-特质焦虑量表（STAI）状态形式的两个六项版本的信度和效度，并确定最适合用于有正常或异常新生儿筛查结果婴儿的父母样本的版本。在本研究中，进行了验证性因素分析，以评估这两个六项形式与从150名婴儿的288名父母在三个时间点收集的STAI数据的拟合度。父母研究组基于婴儿的新生儿筛查及后续诊断测试，包括囊性纤维化（CF；n = 26）、先天性甲状腺功能减退症（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状态形式的第1、3、6、15、16和17项的版本在所有三个时间点都是拟合度更好的模型，并且其内部一致性优于包含第5、9、10、12、17和20项的版本。两个简短形式与20项STAI得分均高度相关，且所有内部一致性信度均大于0.90。得出的结论是，状态焦虑量表中包含第1、3、6、15、16和17项的版本对于本研究样本是一种可靠且有效的工具。
