The instrument included items on periodontal status such as self\u2010perception of gum health, bleeding and gingival infection, halitosis, tooth mobility, and tooth loss. The periodontal clinical condition was assessed using the Periodontal Screening and Recording Index. Construct validity was evaluated by exploratory factor analysis (EFA). Sensitivity, specificity, and area under the receiver operating characteristic curve (AUC\u2010ROC) were calculated as well. Reliability was assessed using Cronbach's alpha.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The prevalence of clinically evaluated moderate (MP) and severe (SP) periodontitis was 49.3% and 28.9%, respectively. Two factors for both types of periodontitis were identified using EFA. The combination of self\u2010report items and risk factors for periodontitis showed an AUC\u2010ROC of 0.660 (sensitivity 97.3%, specificity 3%) for MP and 0.804 (sensitivity 96.9%, specificity 28.3%) for SP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>EFA showed two factors that accounted for the baseline and outcome stage of periodontitis and better predicted the risk of SP.
