The stability of post-traumatic growth over time and the relationship between post-traumatic growth and traditional distress outcomes remains unclear. We tracked post-traumatic growth in a population-based sample of colorectal cancer patients from soon after diagnosis to five years subsequently to assess the heterogeneity of a post-traumatic growth response to cancer over time and describe the simultaneous and longitudinal relationships between post-traumatic growth and psychological distress. 1966 colorectal patients who were five months post diagnosis were assessed six times over a five year period. There was considerable heterogeneity associated with both psychological distress and benefit finding scores over time. However, both for benefit finding and psychological distress, the variation in individual scores suggested an underlying positive linear trend and both lagged and lagged change components. Specifically, benefit finding and psychological distress are mutual leading indicators of each other. First, benefit finding served as a leading indicator of distress, in that increases in reported benefit finding from year to year predicted higher future increases in psychological distress. As well, in an inverse relationship, psychological distress served as a leading indicator of benefit finding, such that increases in reported distress from year to year predicted lower future increases in benefit finding. Post-traumatic growth may reflect patients coping efforts to enhance perceptions of wellbeing in response to escalating cancer-related threats, acting as harbinger of increasing trajectories of psychological distress. This explanation is consistent with a cognitive dissonance response in which threats to the integrity of the self then lead to a tendency to accentuate positive aspects of the self.
创伤后成长随时间的稳定性以及创伤后成长与传统痛苦结果之间的关系仍不明确。我们对一组以人群为基础的结直肠癌患者样本进行了跟踪，从诊断后不久一直到随后的五年，以评估创伤后成长对癌症的反应随时间的异质性，并描述创伤后成长与心理痛苦之间的同步和纵向关系。1966名诊断后五个月的结直肠癌患者在五年内接受了六次评估。随着时间的推移，心理痛苦和益处发现得分都存在相当大的异质性。然而，无论是益处发现还是心理痛苦，个体得分的变化都显示出潜在的正线性趋势以及滞后和滞后变化成分。具体而言，益处发现和心理痛苦是相互的领先指标。首先，益处发现是痛苦的领先指标，即每年报告的益处发现增加预示着未来心理痛苦会有更高的增加。同样，呈反比关系的是，心理痛苦是益处发现的领先指标，即每年报告的痛苦增加预示着未来益处发现的增加会更低。创伤后成长可能反映了患者为应对不断升级的癌症相关威胁而努力增强幸福感认知的过程，同时也是心理痛苦增加轨迹的预兆。这种解释与认知失调反应一致，即对自我完整性的威胁会导致强调自我积极方面的倾向。
