Abstract

This study examined the lay theories of depression in Japanese undergraduate students. People tend to have the lay theories of depression, that is, causes of depression, depressive behaviors, depressive symptoms, and remedies of depression. We investigated the lay theories of depression of Japanese undergraduate students using the SCT method. Three hundred and thirteen Japanese students filled out questionnaires and described their lay theories of depression. The text data obtained from the questionnaire replies was analyzed using a text mining method and the KJ method. The results showed that participants mentioned the characteristics of depression, images of depressed persons, reasons of depression, and treatment for depression. The implications of the results and suggestions for further studies were also discussed.
