This study has certain limitations. First, this study used a cross-sectional study design, and the development, influencing factors, and relationships between PTSD and PTGD are complex and time-varying processes. Therefore, follow-up longitudinal studies can be performed with follow-up. Second, the measured PTGs were mostly retrospective, self-perceived PTGs. Subsequent research can combine clinically relevant evidence and establish external behavioral indicators, such as observing individual behavioral changes, or comprehensive assessments by family members and friends before and after the traumatic event.

This study has some limitations. Firstly, this study adopts a cross-sectional study design, and the development, influencing factors and relationship between PTSD and post-traumatic growth are a complex process that changes over time. Therefore, the follow-up longitudinal study can be carried out through follow-up. Secondly, the measured PTG is mostly retrospective and self perceived PTG. Later research can be combined with clinical relevant evidence and establish external behavior indicators, such as observing individual behavior changes, or comprehensively evaluating through family and friends before and after traumatic events.

This study has some limitations. First of all, this study adopts a cross-sectional study design, and the development, influencing factors and relationship between post-traumatic stress disorder and post-traumatic growth are a complicated process that changes with time. Therefore, follow-up longitudinal study can be conducted. Secondly, the measured PTG is mostly retrospective and self-perceived PTG. After that, we can combine clinical evidence and establish external behavior indicators, such as observing individual behavior changes, or comprehensively evaluating by family and friends before and after traumatic events.
