Patients with PD additionally completed the Questionnaire for Impulsive-Compulsive Disorders in Parkinson\u2019s Disease\u2013Rating Scale. Clinical characteristics and Movement Disorder Society\u2013Unified Parkinson\u2019s Disease Rating Scale scores were assessed.Results SAS scores were lower in PD than in controls. In PD, smartphone use was associated with depressive symptoms, anxiety, non-motor symptom burden, and impulsivity, although none remained independently associated in multivariable analysis. Positive anticipation showed the strongest association with impulsivity. In controls, depressive symptoms were associated only with the overuse and cyberspace-oriented relationships subscales.Conclusion Problematic smartphone use in PD appears to involve multiple behavioral dimensions, with overall use related to mood symptoms and reward-related use more closely linked to impulsivity.<\/jats:p>","DOI":"10.14802\/jmd.26203","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T04:12:22Z","timestamp":1787890342000},"page":"453-457","update-policy":"https:\/\/doi.org\/10.14802\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Problematic Smartphone Use in Parkinson\u2019s Disease: Associations With Mood, Non-Motor Burden, and Impulsivity"],"prefix":"10.14802","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0542-8979","authenticated-orcid":true,"given":"M\u00fcge","family":"Ku\u015fo\u011flu","sequence":"first","affiliation":[{"name":"Department of Neurology, Kartal Dr. L\u00fctfi K\u0131rdar City Hospital, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4919-602X","authenticated-orcid":true,"given":"M\u00fccahid","family":"Erdo\u011fan","sequence":"additional","affiliation":[{"name":"Department of Neurology, Kartal Dr. L\u00fctfi K\u0131rdar City Hospital, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6299-1338","authenticated-orcid":true,"given":"Banu \u00d6zen","family":"Barut","sequence":"additional","affiliation":[{"name":"Department of Neurology, Kartal Dr. L\u00fctfi K\u0131rdar City Hospital, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5803","container-title":["Journal of Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/e-jmd.org\/upload\/pdf\/jmd-26203.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/e-jmd.org\/journal\/view.php?doi=10.14802\/jmd.26203","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/e-jmd.org\/upload\/pdf\/jmd-26203.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,30]],"date-time":"2026-10-30T00:01:24Z","timestamp":1793318484000},"score":1,"resource":{"primary":{"URL":"http:\/\/e-jmd.org\/journal\/view.php?doi=10.14802\/jmd.26203"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,31]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2026,10]]}},"URL":"https:\/\/doi.org\/10.14802\/jmd.26203","relation":{},"ISSN":["2093-4939"],"issn-type":[{"value":"2093-4939","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,31]]},"assertion":[{"value":"2026-07-03","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-25","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-28","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-10-31","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
