The clinical value of derived subscales was explored by comparing scores with age-matched controls (N = 583), and by investigating relationships to demographic and disease- related characteristics.\nResults: All three models showed a good fit in people with PD, with the five-factor model outperforming the three-factor and one-factor model. Five factors were distinguished: ‘Diminished visual perception – Function related’ (5 items), ‘Diminished visual perception – Luminance related’ (3 items), ‘Diminished visual perception – Task related’ (3 items), ‘Altered visual perception’ (6 items), and ‘Ocular discomfort’ (2 items). On each subscale, people with PD reported more complaints than controls, even when there was no ophthalmological condition present. Furthermore, subscales were sensitive to relevant clinical characteristics, like age, disease duration, severity, and medication use.\nConclusions: The five-factor model showed a good fit in people with PD and has clinical relevance. Each subscale provides a solid basis for individualized visual care."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2022"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Medicine, Health and Life Sciences","Social Sciences"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Parkinson disease"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Vision Screening"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Vision Disorders"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Self Report"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Diagnostic Self Evaluation"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Surveys and Questionnaires"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Factor Analysis"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Practice Guideline"}}]},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"Elsenga, Christina"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2022-09-13"}]},"dansDataVaultMetadata":{"displayName":"Data Vault Metadata","name":"dansDataVaultMetadata","fields":[{"typeName":"dansDataversePid","multiple":false,"typeClass":"primitive","value":"doi:10.34894/V9IGKJ"},{"typeName":"dansDataversePidVersion","multiple":false,"typeClass":"primitive","value":"2.0"},{"typeName":"dansBagId","multiple":false,"typeClass":"primitive","value":"urn:uuid:c7c9f011-745d-48b4-aafb-b75d19aee94b"},{"typeName":"dansNbn","multiple":false,"typeClass":"primitive","value":"urn:nbn:nl:ui:13-1856a0e4-c3c9-41d4-a31a-9c7b3637cd9e"}]}},"files":[{"label":"S1_TableOphthalmologicalConditions.pdf","restricted":false,"version":1,"datasetVersionId":24427,"dataFile":{"id":315568,"persistentId":"","filename":"S1_TableOphthalmologicalConditions.pdf","contentType":"application/pdf","friendlyType":"Adobe PDF","filesize":526649,"storageIdentifier":"surf://store:1843d50f55c-15863fa6e5c3","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"ebf25c126648cb6281c7fc290f38304b4144e69b"},"tabularData":false,"creationDate":"2022-11-03","publicationDate":"2022-11-04","lastUpdateTime":"2022-11-04T07:56:47Z","fileAccessRequest":true}},{"label":"S2_SVCqDutch.pdf","restricted":false,"version":1,"datasetVersionId":24427,"dataFile":{"id":315569,"persistentId":"","filename":"S2_SVCqDutch.pdf","contentType":"application/pdf","friendlyType":"Adobe PDF","filesize":390211,"storageIdentifier":"surf://store:1843d50f5c5-833fe01873ad","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"03bd2c65050287fcc5b63cb2cbf49f31be8e6d0b"},"tabularData":false,"creationDate":"2022-11-03","publicationDate":"2022-11-04","lastUpdateTime":"2022-11-04T07:56:47Z","fileAccessRequest":true}},{"label":"S3_SVCqEnglish.pdf","restricted":false,"version":1,"datasetVersionId":24427,"dataFile":{"id":315567,"persistentId":"","filename":"S3_SVCqEnglish.pdf","contentType":"application/pdf","friendlyType":"Adobe PDF","filesize":300150,"storageIdentifier":"surf://store:1843d50f4e3-bca2c76bafcd","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"649edcd147a91fc01a60c24f642ec459a759a86c"},"tabularData":false,"creationDate":"2022-11-03","publicationDate":"2022-11-04","lastUpdateTime":"2022-11-04T07:56:47Z","fileAccessRequest":true}},{"label":"S4_Data.xlsx","restricted":true,"version":1,"datasetVersionId":24427,"dataFile":{"id":309863,"persistentId":"","filename":"S4_Data.xlsx","contentType":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","friendlyType":"MS Excel Spreadsheet","filesize":158568,"storageIdentifier":"surf://store:18337aff179-a13b01929142","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"e7dd2dc7e0bf4f51ca8b0c9e009c6b021b0e6a19"},"tabularData":false,"creationDate":"2022-09-13","publicationDate":"2022-09-14","lastUpdateTime":"2022-11-04T07:56:47Z","fileAccessRequest":true}}]}}}
