“…These results demonstrate that Brief‐IPQ has good overall validity and reliability for use among adult patients with PDs (Cronbach's alpha value of 0.80), being in agreement with the original Brief‐IPQ study (Broadbent et al, ) and within the range of similar chronic diseases researches (Abubakari et al, ; Ashley et al, ). The factorial invariance concerning gender was also confirmed showing, therefore, that the Brief‐IPQ is a reliable instrument to both genders, similarly to previous reports that have employed the IPQ‐Revised questionnaire (Mafla et al, ; Villalobos‐Galvis et al, ).…”

“…The length of questionnaires has a considerable response rate burden resulting in considerable non-response rates (Rolstad, Adler, & Rydén, 2011). Consequently, long questionnaires may have poor interest in the daily clinical practice, and for this purpose, this shortform may be more suitable for patients with this condition (Mafla et al, 2019).…”

“…Recently, the properties of the Illness Perception Questionnaire Revised have been investigated for Oral Health (IPQ‐R‐OH) and in patients with self‐perceived PDs (Mafla, Herrera‐López, & Villalobos‐Galvis, ; Villalobos‐Galvis, Mafla, Burbano‐Trujillo, & Sanchez‐Figueroa, ). In this study, IPQ‐R‐OH revealed to be an interesting tool for potential periodontal patients' screening and education.…”

Aim To investigate the psychometric properties of the validated Portuguese version of the Brief Illness Perception Questionnaire (Brief‐IPQ) in patients with gingivitis and periodontitis. Material and Methods This study enrolled 571 patients with periodontal diseases (PDs) (67 gingivitis and 504 periodontitis cases), in a population‐based epidemiologic survey conducted at the health centres in the South Lisbon Metropolitan Area. Brief‐IPQ, a 9‐item self‐reported scale, reliability was evaluated using Cronbach's alpha. Confirmatory factor analysis (CFA) was used to construct validation. Multigroup analysis tested invariance across gender. Results The Brief‐IPQ showed acceptable reliability (α = .80). Confirmatory factor analysis revealed good model fit (χ2 (16) = 41.236, GFI = 0.982, CFI = 0.985, RMSEA = 0.053). All factors loaded similarly to the original Brief‐IPQ scale, with the exception of the “personal control” domain. Periodontal patients downgrade its illness and likely impact. The “consequences” domain showed significant positive correlations with all factors, except “treatment control” and “understanding” domains. The “concern” and “emotional response” domains had the highest significant correlation. Multigroup analysis findings supported factor invariance across the sex groups. Conclusion The Brief‐IPQ revealed acceptable reliability, construct factorial validity and invariance across gender. This short instrument may be used as an easily applicable and valuable tool to determine illness perception in patients with PDs.

“…Finally, all CSM factors formed unidimensional scales, an important finding since it validates the calculation of summative factor scores. More recently [32, 33], a revised Illness Perception Questionnaire for Oral Health (IPQ-R-OH) has been developed in Spanish for adults 18 years or older with caries and periodontal disease. The IPQ-R-OH was reported to have acceptable construct validity and reliability, however, this is not an integrated measure specific for older adults.…”

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.

“…Illness representation is a cognitive and emotional‐based construct through direct and indirect personal experiences, as well as the information received from the social environment and health professionals (Leventhal et al, 1992). Recently, the Illness Perception Questionnaire‐Revised‐Oral Health (IPQ‐R‐OH) and the Brief Illness Perception Questionnaire (Brief‐IPQ) were successfully validated for patients with periodontal disease (Machado et al., 2019; Mafla, Herrera‐López, & Villalobos‐Galvis, 2018). In particular, the Brief‐IPQ showed acceptable reliability, construct factorial validity and invariance across gender making this short questionnaire a pertinent and beneficial instrument to determine periodontal disease perception (Machado et al., 2019).…”

Aim To investigate the impact of periodontal disease perception and oral health‐related quality of life (OHRQoL), towards the initial periodontal treatment adherence (IPTA). Material and Methods This prospective study included 571 patients (274 males and 297 females, mean age 63.1 ± 14.5) with periodontal disease, from the Study of Periodontal Health in Almada‐Seixal (SoPHiAS). We assessed the potential connections, between sociodemographic characteristics, oral hygiene behaviours, periodontal measures, the Brief Illness Perception Questionnaire (IPQ) and the Oral Health Impact Profile (OHIP‐14), through a structural equation modelling (SEM). Multivariate logistic regression assessed significant oral health‐related variables towards IPTA. Results Overall, 265 participants had IPTA (46.4%). The SEM had a good fit to the data on all six latent variables (χ2 = 2.221, CFI = 0.921, RMSEA = 0.0.046). Multivariate analysis for IPTA indicated Treatment Control (Odds Ratio [OR] = 1.07) and Identity domains of Brief‐IPQ (OR = 1.10) and Functional Limitation domain of OHIP‐14 (OR = 1.60) as significant predictors. The obtained tool had a satisfactory prediction of IPTA (61.1%). Conclusions Initial periodontal treatment adherence is influenced by patient's perception on periodontal disease treatment and identity domains and by functional impact domain of OHRQoL. Future studies shall investigate the effect of modelling these domains on therapeutic success and public health strategies.
