The sociodemographic information of patients and their questionnaires including the Generalised Anxiety Disorder 7\u2010item (GAD\u20107), Patient Health Questionnaire 9\u2010item (PHQ\u20109), and Jaw Functional Limitation Scale\u20108 (JFLS\u20108) were collected. Patients were divided into the high\u2010income and low\u2010income groups based on a household per capita income of 6000 RMB per month. Multiple regression and mediation analysis were used to explore the association between variables. The bootstrap method was applied to estimate confidence intervals (CIs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Higher JFLS\u20108 scores were significantly correlated with higher GAD\u20107 scores (<jats:italic>r<\/jats:italic>\u2009=\u20090.361, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), PHQ\u20109 scores (<jats:italic>r<\/jats:italic>\u2009=\u20090.339, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001).
