The purpose of this study was to calibrate an item set for a new version of the Communicative Participation Item Bank (CPIB) specifically for use with gender-diverse clients. This new version contains a new item stem as well as other minor wording changes from the original CPIB in order to be acceptable to gender-diverse respondents.
Survey data on 47 candidate items were collected from 434 transgender individuals: 219 assigned female at birth (AFAB) and 215 assigned male at birth (AMAB). Item response theory analyses included evaluation of unidimensionality, local dependence, fit to a graded response model, and differential item functioning (DIF) between AFAB and AMAB respondents.
The original set of 47 items was unidimensional, but 16 items were removed due to local dependence, resulting in a final item bank of 31 items. There was no evidence of DIF between AFAB and AMAB participants. Reliability of the full item bank is good (i.e., > 0.8) between scores of 20 and 76 and high (i.e., > 0.9) between scores of 20 and 68. The short form had good reliability (i.e., > 0.8) between scores of 24 and 64.
The Communicative Participation Item Bank-Gender-Diverse (CPIB-GD) version provides a new option for person-reported outcome measurement with gender-diverse clients. Clinicians are cautioned to use only the new CPIB-GD with gender-diverse clients, and not the original CPIB due to unacceptable wording in the original version for this population. The original CPIB remains valid and appropriate for the populations for which it was developed.
本研究旨在为新的沟通参与项目库（CPIB）版本校准项目集，该版本专门用于性别多样化的客户。新版本包含一个新的项目标题以及原始 CPIB 中的其他轻微措辞更改，以便为性别多样化的受访者所接受。
从 434 名跨性别个体中收集了 47 个候选项目的调查数据：219 名出生时被指定为女性（AFAB），215 名出生时被指定为男性（AMAB）。项目反应理论分析包括评估单维性、局部依赖性、对渐进反应模型的拟合以及 AFAB 和 AMAB 受访者之间的差异项目功能（DIF）。
原始的 47 个项目集是单维的，但由于局部依赖性，有 16 个项目被删除，最终项目库由 31 个项目组成。AFAB 和 AMAB 参与者之间没有证据表明存在 DIF。在 20 到 76 分的范围内，整个项目库的可靠性良好（即>0.8），在 20 到 68 分的范围内，可靠性高（即>0.9）。在 24 到 64 分的范围内，短形式具有良好的可靠性（即>0.8）。
沟通参与项目库-性别多样化（CPIB-GD）版本为性别多样化的客户提供了一种新的个体报告结果测量选择。临床医生被警告只在性别多样化的客户中使用新的 CPIB-GD，而不要使用原始的 CPIB，因为原始版本中的措辞对该人群来说是不可接受的。原始的 CPIB 仍然有效且适用于为其开发的人群。
