Depression is a major social concern in Japan. It is therefore necessary to develop a scale in Japanese that can assess depression literacy.
Aims:
The present study aimed to develop the Japanese version of the Depression Literacy Scale (D-Lit-J), and examined its validity and reliability.
Methods:
Three groups were administered the D-Lit-J, including 117 first-year university English literature students, 112 first-year medical school students, and 53 psychiatrists. Among these, 112 (95.7%), 112 (100%), and 29 subjects (54.7%) returned completed questionnaires, respectively. The total D-Lit-J scores were compared between the three groups to assess known-group validity, and internal reliability was examined by calculating Cronbach’s alpha coefficients. Medical students were asked to complete the questionnaire a second time, 3 weeks later (11 students did not respond), to assess the test–retest reliability using the intra-class correlation coefficient.
Results:
The total D-Lit-J scores (mean ± SD) were 7.61 ± 4.18, 9.51 ± 4.37, and 17.7 ± 3.15, for English literature students, medical students, and psychiatrists, respectively, and there were significant differences between the three groups (p |

The Cronbach’s alpha coefficients ranged from .800 to .834 in all students, and was .764 in psychiatrists, revealing a good internal consistency. The intra-class correlation coefficient of the scale was .769.
Conclusions:
The D-Lit-J showed a credible known-group validity, with good internal and test–retest reliabilities. Additional studies with a greater variety of subjects and that examine concurrent or discriminant validity will be necessary in the future.</description><identifier>ISSN: 0020-7640</identifier><identifier>EISSN: 1741-2854</identifier><identifier>DOI: 10.1177/00207640211057728</identifier><identifier>PMID: 36281522</identifier><language>eng</language><publisher>London, England: SAGE Publications</publisher><subject>College students ; Depression ; Discriminant validity ; English literature ; Humans ; Japan ; Japanese language ; Literacy ; Medical schools ; Medical students ; Mental depression ; Psychiatrists ; Questionnaires ; Reliability ; Reproducibility of Results ; Surveys and Questionnaires ; Validity</subject><ispartof>International journal of social psychiatry, 2022-12, Vol.68 (8), p.1708-1715</ispartof><rights>The Author(s) 2021</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c368t-aacd1754c94962dbc35cbaecd489ced4a409a05f7623aecba7b9c74c852017aa3</citedby><cites>FETCH-LOGICAL-c368t-aacd1754c94962dbc35cbaecd489ced4a409a05f7623aecba7b9c74c852017aa3</cites><orcidid>0000-0003-3537-5657</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/00207640211057728$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/00207640211057728$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>314,780,784,21817,27922,27923,30997,43619,43620</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/36281522$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Imano, Tomomi</creatorcontrib><creatorcontrib>Yokoyama, Kazuhito</creatorcontrib><creatorcontrib>Itoh, Hiroaki</creatorcontrib><creatorcontrib>Shoji, Eri</creatorcontrib><creatorcontrib>Asano, Keiko</creatorcontrib><title>Development of the Japanese version of the Depression Literacy Scale</title><title>International journal of social psychiatry</title><addtitle>Int J Soc Psychiatry</addtitle><description>Background:
