AB  - BACKGROUND: Based on the Common-Sense Model of Self-Regulation (CSM), a new 
      integrated Illness Perception Questionnaire Revised for Dental Use in Older/Elder 
      Adults (IPQ-RDE) was developed for single and multiple dental conditions. This 
      study describes psychometric properties of the IPQ-RDE for adults 62 years and 
      older. METHODS: Participants (n = 198) living in 16 subsidized housing facilities 
      completed the IPQ-RDE and a questionnaire assessing their socio-demographics, 
      frequency of dental visits, perceived condition of teeth/gums, depression, social 
      support, and oral health quality of life (OHQOL). Participants received dental 
      screening for presence/absence of teeth, coronal and root caries, and 
      periodontitis. The 43-item IPQ-RDE was tested for internal (construct, 
      discriminant) and external validity (concurrent, construct, discriminant, 
      predictive) and reliability (internal consistency). RESULTS: Confirmatory factor 
      analysis demonstrated that a ten-factor model in accordance with the CSM 
      framework (identity, consequences, control, timeline, illness coherence, 
      treatment burden, prioritization, causal relationship, activity restriction, 
      emotional representations) had good construct validity based on significant 
      factor loadings and acceptable model fit (RMSEA = 0.065, CFI = 0.902). Edentulous 
      participants had significantly higher mean factor scores (inaccurate perception) 
      for overall IPQ-RDE and four constructs indicating concurrent validity. 
      Discriminant validity was suggested by non-relationship with external measures 
      (education, dental visit frequency). Predictive validity was indicated by the 
      negative correlation of most constructs with OHQOL suggesting that inaccurate 
      perception was related to lower quality of life. Internal consistency of eight 
      IPQ-RDE constructs was excellent (Cronbach's alpha > 0.73). CONCLUSIONS: The 
      IPQ-RDE is a valid and reliable new measure for assessing older adult's 
      perception of dental conditions. It can be an important tool for oral health 
      behavioral research to restructure older adult's perception of dental conditions, 
      and subsequently prevent tooth loss and improve oral health quality of life.
