Posttraumatic growth has garnered increasing interest as a potential positive consequence of traumatic events and illnesses. However, scientific investigations have yet to demonstrate the validity of self-reports of posttraumatic growth. The most common measure used to assess this construct is the Post Traumatic Growth Inventory (PTGI); however, the extent to which the PTGI (as well as other self-report measures of perceived posttraumatic growth; PPTG) assess actual positive change remains unknown. The present study aimed to examine the validity of PPTG measures. We assessed 83 adolescent and young adult (AYA) cancer survivors at two time points, one year apart. We measured the stability of PTGI from T1 to T2, correlated three measures of PPTG that used different methods (only positive, positive or negative, positive and negative change) with wellbeing measures, and compared PTGI scores with changes in psychosocial resources. PTGI scores were stable over time. More nuanced measures of PPTG appeared to capture more perceived change, although no measure of PPTG was favorably related to wellbeing. Finally, PTGI did not correlate with change in psychosocial resources, with the exception of spirituality. Overall, our results suggest that measures of PPTG do not capture actual positive changes experienced by AYA cancer survivors.
创伤后成长作为创伤事件和疾病可能产生的积极后果，已引起越来越多的关注。然而，科学研究尚未证实创伤后成长自我报告的有效性。用于评估这一概念的最常用方法是创伤后成长问卷（PTGI）；然而，PTGI（以及其他创伤后成长感知的自我报告测量方法；PPTG）在多大程度上评估了实际的积极变化仍不明确。本研究旨在检验PPTG测量方法的有效性。我们在两个时间点对83名青少年和青年成年（AYA）癌症幸存者进行了评估，两个时间点相隔一年。我们测量了从T1到T2的PTGI稳定性，将三种使用不同方法（仅积极、积极或消极、积极和消极变化）的PPTG测量方法与幸福感测量方法进行了关联，并将PTGI得分与心理社会资源的变化进行了比较。PTGI得分随时间保持稳定。更细致入微的PPTG测量方法似乎能捕捉到更多的感知变化，尽管没有一种PPTG测量方法与幸福感呈正相关。最后，除了精神层面外，PTGI与心理社会资源的变化没有相关性。总体而言，我们的结果表明，PPTG测量方法并未捕捉到AYA癌症幸存者实际经历的积极变化。
