This study aimed to explore whether sandplay therapy could offer an effective psychological intervention for
middle school students with posttraumatic stress disorder (PTSD). We conducted sandplay therapy on six
occasions with second-grade middle school students with PTSD and subsequently observed a significant
decrease in their PTSD total scores. Our follow-up assessments of the subjects six months later showed that
the related indicators remained within an acceptable range. Based on these results, we have concluded that
sandplay therapy offers an effective psychological intervention for teenagers with PTSD.
