{"doi":"10.17615/d891-7848","title":"Development of the Two Stage Rapid Estimate of Adult Literacy in Dentistry (TS-REALD)","abstract":"This work proposes a revision of the 30 item Rapid Estimate of Adult Literacy in Dentistry (REALD-30), into a more efficient and easier-to-use two-stage scale. Using a sample of 1,405 individuals (primarily women) enrolled in a Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), the present work utilizes principles of item response theory and multi-stage testing to revise the REALD-30 into a two-stage test of oral health literacy, named Two-Stage REALD or TS-REALD, which maximizes score precision at various levels of participant ability. Based on the participant’s score on the 5-item first-stage (i.e., routing test), one of three potential stage-two tests is administered: a 4-item Low Literacy test, a 6-item Average Literacy test, or a 3-item High Literacy test. The reliability of scores for the TS-REALD is greater than .85 for a wide range of ability. The TS-REALD was found to be predictive of perceived impact of oral conditions on well-being, after controlling for educational level, overall health, dental health, and a general health literacy measure. While containing approximately one-third of the items on the original scale, the TS-REALD was found to maintain similar psychometric qualities.","journal":"UNC Libraries","year":2020,"id":143060,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9369,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":532603,"name":"Shoou-Yih Daniel Lee","orcid":null,"position":1,"is_corresponding":false},{"id":548052,"name":"Brian D.
