Frailty, characterized by reduced physical and psychological resistance, predicts the incidence of dependency and mortality. Although low self-disclosure may be associated with frailty, there is no scale to measure older adults\u2019 self-disclosure. This cross-sectional study assessed the validity of a self-assessment self-disclosure questionnaire and examined the association between the content of self-disclosures to friends and acquaintances and frailty among community-dwelling older adults. A total of 237 adults aged \u226565 in Japan were surveyed using a mailed self-administered questionnaire in 2021. The self-disclosure scale consisted of 10 items and showed adequate validity. Participants were classified into a robust group (n = 117, women 57.3%) and a frailty group (n = 120, women 73.3%) using the Kihon Checklist. After adjusting for covariates, multivariate-adjusted logistic regression models revealed frailty was associated with lower self-disclosure of recent positive events, motivation and strengths (indicating strong points) in life, relationships with family and relatives, experiences of work and social activities, and financial status. The proposed questionnaire must still be further tested in other populations, but our initial results may contribute to preventing frailty and improving mental health among community-dwelling older adults.<\/jats:p>","DOI":"10.3390\/geriatrics9030067","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T10:14:07Z","timestamp":1716804847000},"page":"67","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Development of the Self-Assessment Self-Disclosure Questionnaire to Examine the Association between Self-Disclosure and Frailty among Community-Dwelling Older Adults in Japan"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9865-7200","authenticated-orcid":false,"given":"Kazuki","family":"Yokoyama","sequence":"first","affiliation":[{"name":"Department of Occupational Therapy, School of Health Sciences, Sapporo Medical University, Sapporo 060-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hikaru","family":"Ihira","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, School of Health Sciences, Sapporo Medical University, Sapporo 060-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3697-4646","authenticated-orcid":false,"given":"Yuriko","family":"Matsuzaki-Kihara","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Japan Health Care University, Sapporo 062-0053, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Mizumoto","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Faculty of Human Science, Hokkaido Bunkyo University, Eniwa 061-1449, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideyuki","family":"Tashiro","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, School of Health Sciences, Sapporo Medical University, Sapporo 060-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyotaka","family":"Shimada","sequence":"additional","affiliation":[{"name":"Department of Neuropsychiatry, School of Medicine, Sapporo Medical University, Sapporo 060-8543, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kosuke","family":"Yama","sequence":"additional","affiliation":[{"name":"N Field Home-Visit Nursing Station Dune Sapporo, Sapporo 003-0808, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Miyajima","sequence":"additional","affiliation":[{"name":"Ebetsu City Hospital, Ebetsu 067-8585, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, School of Health Sciences, Sapporo Medical University, Sapporo 060-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Kozuka","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Hokkaido Chitose College of Rehabilitation, Chitose 066-0055, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nozomu","family":"Ikeda","sequence":"additional","affiliation":[{"name":"Department of Occupational Therapy, School of Health Sciences, Sapporo Medical University, Sapporo 060-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,26]]},"container-title":["Geriatrics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mdpi.com\/2308-3417\/9\/3\/67\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T14:49:06Z","timestamp":1760107746000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mdpi.com\/2308-3417\/9\/3\/67"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,5,26]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024,6]]}},"alternative-id":["geriatrics9030067"],"URL":"https:\/\/doi.org\/10.3390\/geriatrics9030067","relation":{},"ISSN":["2308-3417"],"issn-type":[{"value":"2308-3417","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,5,26]]}}}
