#the need for follow-up research and basic data were sought. Methods To this end

#type of study

#we could see that depression in single-person households was ac tively used as a subordinate. The trend analysis by factor found that there were many studies on risk factors that increased depression in single-person households. Conclusions It can be seen that Korean researchers are increasingly interested in understanding the depression of single-person households and pursuing psychological and mental health. And subsequent studies using vari ous perspectives of academic approaches and variables associated with depression can be expected.

#we want to understand the trend of research intervention in depression and analyze factors that affect depression by considering domestic research on depression in single-person households. Recognizing the increasing severity of depression in single-person households
