本研究旨在瞭解COVID-19事件下，不同背景變項、創傷後成長、不同社會支持程度與創傷後壓力症、與心理健康的關係及影響。採網路問卷調查法，以居住於臺灣且年滿20歲者為研究樣本，進行網路調查，有效樣本413名。研究工具包含「創傷後心理症狀指標量表-短版」、「中文版創傷後成長量表」、「心理健康BMI幸福心指標量表」、「社會支持簡式量表」。重要研究結果如下：（1）COVID-19事件之創傷影響，可能因調查時間點疫情嚴重程度差異而有不同；（2）女性、年輕人或過去有創傷經驗者受COVID-19影響的心理反應較顯著；（3）創傷後成長與感知創傷壓力程度有正向關係，然而當創傷後壓力症高於某個程度後其間的關係即不存在；（4）疫情下可預測心理健康的因子為社會支持與創傷後成長。最後，根據研究結論提出促進心理健康之相關輔導與諮商建議。

This study aims to understand the relationships and influences among different background variables, post-traumatic growth, varying levels of social support, post-traumatic stress symptoms, and mental health in the context of the COVID-19 pandemic. The subjects of the study were those who lived in Taiwan and were over 20 years old. Online questionnaire survey was administered as a research method, with a total number of 413 effective samples. The research instruments used include " Interpersonal Support Evaluation List — 16 item", " Post-traumatic Stress Reaction Index-Short Form ", "Post-traumatic growth inventory- Chinese Version", and "Mental Health BMI Index ". The results of the study are as follows:(1) Taiwanese people experience less traumatic impact from COVID-19. (2) Women, young people or those with traumatic experience in the past have more significant psychological reactions affected by COVID-19. (3) Post-traumatic Growth is positively related to perceived post-traumatic stress. However, the relationship between the two did not exist when PTSD was above a certain level. (4) Social support and Post-traumatic Growth are the predictors of mental health during the COVID-19 epidemic. Based on these findings, recommendations for counseling and guidance to enhance mental well-being are proposed.
