描述了创伤后成长量表（PTGI-SF）的简短形式。在以前的研究中完成了创伤后成长量表（PTGI）的1351名成年人的样本提供了项目选择的基础。由此产生的10个项目的形式包括两个项目，从每个原始PTGI的五个分量表，选择的基础上加载的原始因素和项目内容的广度。一个单独的样本186完成了简短的规模（PTGI SF）。两个数据集的验证性因素分析表明，PTGI-短形式（PTGI-SF）相当于PTGI的五个因素的结构。三项同质临床样本（丧亲父母，亲密伴侣暴力受害者和急性白血病患者）的研究表明，PTGI-SF与其他感兴趣的变量的关系，相当于使用PTGI的原始形式。最后一项研究表明，以随机顺序而不是在原始量表的固定背景下管理10个简短项目不会影响PTGI-SF的性能。总体而言，这些结果表明，PTGI-SF可以替代PTGI，几乎没有信息损失。
A short form of the Posttraumatic Growth Inventory (PTGI-SF) is described. A sample of 1351 adults who had completed the Posttraumatic Growth Inventory (PTGI) in previous studies provided the basis for item selection. The resulting 10-item form includes two items from each of the five subscales of the original PTGI, selected on the basis of loadings on the original factors and breadth of item content. A separate sample of 186 completed the short form of the scale (PTGI-SF). Confirmatory factor analyses on both data sets demonstrated a five-factor structure for the PTGI-short form (PTGI-SF) equivalent to that of the PTGI. Three studies of homogenous clinical samples (bereaved parents, intimate partner violence victims, and acute leukemia patients) demonstrated that the PTGI-SF yields relationships with other variables of interest that are equivalent to those found using the original form of the PTGI. A final study demonstrated that administering the 10 short-form items in a random order, rather than in the fixed context of the original scale, did not impact the performance of the PTGI-SF. Overall, these results indicate that the PTGI-SF could be substituted for the PTGI with little loss of information.
