The current study developed and examined the performance of a computerized adaptive version of the Social Interaction Anxiety and Social Phobia Scales (SIAS/SPS) and compared results with a previously developed static short form (SIAS-6/SPS-6) in terms of measurement precision, concordance with the full forms, and sensitivity to treatment. Among an online sample of Australian adults, there were relatively minor differences in the performance of the adaptive tests and static short forms when compared with the full scales. Moreover, both adaptive and static short forms generated similar effect sizes across treatment in a clinical sample. This provides further evidence for the use of static or adaptive short forms of the SIAS/SPS rather than the lengthier 20-item versions. However, at the individual level, the adaptive tests were able to maintain an acceptable level of precision, using few items as possible, across the severity continua in contrast to the static short forms.
本研究开发并检验了社会交往焦虑症和社交恐惧症量表(SIAS/SPS)的计算机自适应版本的性能,并比较了该自适应版本与先前开发的精简短式版本(SIAS-6/SPS-6)在测量精度、与全式量表的一致性以及对治疗的敏感性方面的差异。在澳大利亚成年人的在线样本中,与全式量表相比,自适应测试和精简短式版本的性能差异相对较小。此外,在临床样本中,自适应和精简短式版本在治疗过程中都产生了相似的效果大小。这进一步证明了使用 SIAS/SPS 的精简或自适应短式版本而不是更长的 20 项版本的合理性。然而,在个体水平上,自适应测试在整个严重程度连续体上,与精简短式版本相比,使用尽可能少的项目,仍然能够保持可接受的精度水平。
