Cross-cultural adaptations of the oral health impact profile - An assessment of global availability of 4-dimensional oral health impact characterization

Linking patient-reported oral and general health-related quality of life

Background

The relationship between oral and overall health is of interest to health care professionals and patients alike. This study investigated the correlation between oral health-related quality of life (OHRQoL) and health-related quality of life (HRQoL) in a general adult population.

Methods

This cross-sectional study used a convenience sample of adult participants (N = 607) attending the 2022 Minnesota County and State fairs in USA, the 5-item Oral Health Impact Profile (OHIP-5) assessed OHRQoL, and the 10-item PROMIS v.1.2 Global Health Instrument assessed HRQoL. Spearman and Pearson correlations were used to summarize the bivariable relationship between OHRQoL and HRQoL (both physical and mental health dimensions). A structural equation model determined OHRQoL-HRQoL correlations (r). Correlations' magnitude was interpreted according to Cohen's guidelines (r = 0.10, 0.30, and 0.50 to demarcate "small," "medium," and "large" effects, respectively).

Results

OHRQoL and HRQoL correlated with r = 0.52 (95% confidence interval, CI: [0.50-0.55]), indicating that the two constructs shared 27% of their information. According to Cohen, this was a "large" effect. OHRQoL, and the physical and mental HRQoL dimensions correlated with r = 0.55 (95% CI: [0.50-0.59]) and r = 0.43 (95% CI: [0.40-0.46]), respectively, indicating a "large" and a "medium" effect. OHRQoL and HRQoL were substantially correlated in an adult population.

Conclusion

Using OHIP-5 to assess their dental patients' oral health impact allows dental professionals to gain insights into patients' overall health-related wellbeing.

Impact of periodontitis on oral health-related quality of life of patients with psoriatic arthritis

BACKGROUND

Since oral health issues can have a negative influence on a person's physical functioning, social status, and wellbeing, oral health-related quality of life (OHRQoL) becomes an indispensable part of overall health. Previous published studies report that periodontitis (PD) and psoriatic arthritis (PsA) have a significant negative impact on OHRQoL. Based on these findings, it would be reasonable to assume that patients with coexisting PsA and PD would see a comparable or maybe synergistic effect on their OHRQoL. Hence, the aim of the present study is to evaluate the OHRQoL and its impact among subjects with concurrent PsA and PD.

MATERIAL AND METHODS

The present study was a comparative, cross-sectional investigation. A total of 200 participants were categorized into four groups- PD-PsA (n = 50), PsA (n = 50), PD (n = 50), and healthy controls (n = 50). Demographic data and periodontal parameters-plaque index, sites with gingival bleeding, probing pocket depth, gingival recession, and clinical attachment level were recorded for all the four groups. Number of mobile teeth due to periodontitis was recorded for the PSA-PD and PD groups. OHIP-14 questionnaire was administered to all the four groups. Collected data was then subjected to statistical analysis.

RESULTS

The severity of OHIP-14 summary scores was highest in the PsA-PD group (18.06 ± 11.22) followed by the PD group (17.02 ± 9.99) and lowest in the healthy group (6.32 ± 5.59) (p < .0001). The scores of all the domains- oral pain, oral function, orofacial appearance and psychological impact were highest among the PsA-PD group followed by the PD group (p < .0001). The combined interaction of PsA and PD on the OHRQoL was statistically significant (F = 6.33, p = .012). Results of the multiple linear regression analysis indicated that there was a moderate collective significant effect between age, past dental visit, frequency of daily tooth brushing, use of other oral hygiene aids, and OHIP-14 (F(3,196) = 13.08, p < .001, R2 = 0.17, adjusted R2 = 0.15).

CONCLUSION

The negative impact on OHRQoL was highest in the patients with concurrent presence of PD with PsA followed by those with PD alone. While the summary scores and dimensional scores of OHIP-14 were insignificant when patients with PsA-PD and PD alone were compared, these scores were significantly higher in patients with PsA-PD than patients with PsA alone.

DENTAL PATIENT-REPORTED OUTCOMES IN GERIATRIC DENTISTRY : A call for clinical translation

As the proportion of older adults in the world population increases, there is an increasing need to provide adequate dental care for this very heterogeneous group of individuals. The relationship between oral and systemic health, the impact of medication on oral health, and the influence of accessibility to dental care and other social and environmental factors shape the provision of dental care for older adults more than in children, younger, and middle-aged adults. However, while dental care for older adults is shaped by these factors and is often different from the care for other adults, what matters to older dental patients does not differ from what matters to dental patients in general. The four dimensions of oral health-related quality of life (OHRQoL)-Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact-capture dental patients' suffering from oral disorders. OHRQoL questionnaires can be used to assess this impact and to achieve results that are compatible with adults in general. More than in other age groups, cognitive impairments or dementia limit the usefulness of questionnaires or interviews for oral health impact assessment. In these situations, family members or caregivers can assess the patient's oral health impact, and oral health care providers need to rely more on physical oral health characteristics for clinical decision-making than in other dental patients. While the tools to measure oral health impact change, the targets for dental care stay the same. Prevention and reduction of functional, painful, aesthetical, and broader psychosocial impact related to oral disorders are the central tasks for geriatric dentistry as they are for dentistry in general. The aim of the manuscript is to highlight the importance of patient-reported outcome measures in geriatric dentistry, addressing challenges and opportunities for their application.

The oral health impact of dental hygiene and dental therapy populations: a systematic review

OBJECTIVES

Oral health-related quality of life (OHRQoL) is pivotal in patient care, reflecting oral health through dental patient-reported outcomes (dPROs). This systematic review aims to outline the 4-dimensional (4-D) impact of OHRQoL within patient populations routinely treated by dental hygiene and/or dental therapy providers, as there is limited literature present for these oral health care professionals.

METHODS

The study extracted and analyzed characteristics and multidimensional impact of OHRQoL, using the Oral Health Impact Profile (OHIP) as the primary dental patient-reported outcome measure (dPROM). The search strategy spanned 7 databases: Medline via the Ovid interface (Ovid MEDLINE(R) ALL), Embase via Ovid, Cinahl, APA PsycINFO via Ovid, Dentistry and Oral Sciences Search, Scopus, and Web of Science (Core Collection). It commenced September 2, 2022, with a refinement search on July 5, 2023. English language criteria yielded 645 articles postduplication removal. A screening procedure involving 3 reviewers encompassed title, abstract, and full-text review.

RESULTS

After application of inclusion and exclusion criteria, 5 articles were subjected to data extraction, capturing domain-specific information including baseline and follow-up OHRQoL data. An additional set of 13 articles containing summarized OHRQoL data underwent separate analysis. The Joanna Briggs Institute (JBI) critical appraisal tools were utilized for risk bias assessment of the included articles. The 4-D impact scores reported for baseline OHRQoL data, ranged from 3.10 to 4.20 for Oral Function, 0.84-2.70 for Orofacial Pain, 1.70-4.50 for Orofacial Appearance, and 0.44-2.50 for Psychosocial Impact. In follow-up OHRQoL data, the range for Oral Function was 1.52-3.60, Orofacial Pain 0.60-2.10, Orofacial Appearance 0.91-2.25, and Psychosocial Impact 0.10-0.60.

CONCLUSIONS

This review highlights a critical call for standardization in OHRQoL data collection for dental hygiene and dental therapy patient populations as only 26% of the predetermined distinct populations were found to have studies completed with 4-D impact of OHRQoL. Moreover, the presence of limited research in describing the multi-dimensional impact in patients routinely treated by these providers shows the urgency of substantive research in this area.

OHIP-5 FOR SCHOOL-AGED CHILDREN

BACKGROUND

Different dental patient-reported outcome measures (dPROMs) exist for children and adults, leading to an incompatibility in outcome assessment in these 2 age groups. However, the dental patient-reported outcomes (dPROs) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the same in the 2 groups, providing an opportunity for compatible dPRO assessment if dPROMs were identical. Therefore, we adapted the 5-item Oral Health Impact Profile (OHIP-5), a recommended dPROM for adults, to school-aged children to allow a standardized dPRO assessment in individuals aged 7 years and above.

AIM

It was the aim of this study to develop a 5-item OHIP for school-aged children (OHIP-5School) and to investigate the instrument's score reliability and validity.

METHODS

German-speaking children (N = 95, mean age: 8.6 years +/- 1.3 years, 55% girls) from the Department of Pediatric Dentistry at the Medical University of Vienna, Austria and a private dental practice in Bergisch Gladbach, Germany participated. The original OHIP-5 was modified and adapted for school going children aged 7-13 years and this modified version was termed OHIP-5School. It's score reliability was studied by determining scores' internal consistency and temporal stability by calculating Cronbach's alpha and intraclass correlation coefficients, respectively. Construct validity was assessed comparing OHIP-5School scores with OHIP-5 as well as Child Perceptions Questionnaire (CPQ-G8-10) scores.

RESULTS

Score reliability for the OHIP-5School was "good" (Cronbach's alpha: 0.81) or "excellent" (Intraclass correlation coefficient: 0.92). High correlations between OHIP-5School, OHIP-5, and CPQ-G8-10 scores were observed and hypotheses about a pattern of these correlations were confirmed, providing evidence for score validity.

CONCLUSION

The OHIP-5School and the original OHIP-5 are short and psychometrically sound instruments to measure the oral health related quality of life in school-aged children, providing an opportunity for a standardized oral health impact assessment with the same metric in school-aged children, adolescents, and adults.

Validation of the HeLD-14 functional oral health literacy instrument in a general population

Background

Oral health literacy (OHL) is recognized as an important determinant of oral outcomes. Measuring OHL with a valid and reliable instrument that accurately captures the functional nature of this construct across cultures is needed. The short version of the Health Literacy in Dentistry scale (HeLD-14) shows promise as an appropriate instrument due to its inclusion of comprehensive domains hypothesized to comprise OHL. While studies validating the instrument in several languages have occurred, the number of dimensions in the various analyses range from one to seven. Validation of the HeLD-14 in a general English-speaking population is also lacking. The purpose of this study was to explore and confirm the dimensionality of the HeLD-14 in a general US English-speaking population.

Methods

The psychometric properties of HeLD-14 were evaluated in a sample of 631 participants attending the Minnesota State Fair. Construct validity was assessed using exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) on the data set split into two groups. Internal consistency reliability was assessed using the Cronbach's alpha coefficient. Concurrent validity was established between the HeLD-14 and the Oral Health Inventory Profile (OHIP-5) using Pearson's correlation.

Results

EFA found, and CFA reinforced, a unidimensional structure of the HeLD-14. Cronbach's alpha was acceptable at 0.92. Fit assessment also supported a unidimensional structure, comparative fit index = 0.992, Tucker-Lewis index = 0.991, root mean square error of approximation = 0.065, and standardized root mean square residual = 0.074. Concurrent validity analyses showed that the HeLD-14 correlated with the OHIP-5.

Conclusions

The HeLD-14 is a unidimensional reliable and valid instrument for measuring the oral health literacy in the general US English-speaking adult population.

Factorial structure and measurement invariance of the Chinese version of the Oral Health Impact Profile-14 among clinical populations and non-clinical populations: an evidence for public oral investigations

OBJECTIVE

Oral health-related quality of life (OHRQoL) is a multidimensional concept that is commonly used to examine the impact of oral health status on quality of life. The purpose of this study was to examine the optimal factor model of the Chinese version of the Oral Health Impact Profile (OHIP-14) questionnaire in clinical populations, measurement invariance across clinical status and gender cohorts. This would ensure equal validity of the Chinese version of OHIP-14 in different populations and further support public oral investigations.

METHODS

The Chinese version of OHIP-14 was used to investigate 490 dental patients and 919 college students. Confirmatory factor analysis (CFA), item analysis and reliability, measurement invariance, and the t-test were used for data analyses.

RESULTS

We found that the 7-factor structure had the best-fit index in the sample (CFI = 0.970, TLI = 0.952; SRMR = 0.029, RMSEA = 0.052(0.040,0.063)). The reliability of the scales was satisfactory (Cronbach's α = 0.942). The error variance invariance fitted the data adequately in measurement invariance, indicating that measurement invariance is acceptable both across the clinical and non-clinical populations (∆CFI=-0.017, ∆RMSEA = 0.010) and across genders in the clinical population (∆CFI = 0.000, ∆RMSEA=-0.003). T-test for scores showed that the clinical populations scored significantly higher than the non-clinical populations, as did the overall score (t = 7.046, p < 0.001, d = 0.396), in terms of functional limitation (t = 2.178, p = 0.030, d = 0.125), physical pain (t = 7.880, p < 0.001,d = 0.436), psychological discomfort (t = 8.993, p < 0.001, d = 0.514), physical disability (t = 6.343, p < 0.001, d = 0.358), psychological disability (t = 5.592, p < 0.001, d = 0.315), social disability (t = 5.301, p < 0.001,d = 0.304), social handicap (t = 4.452, p < 0.001, d = 0.253), and that in the non-clinical populations, females scored significantly higher than males, as did in terms of physical pain (t = 3.055, p = 0.002, d = 0.280), psychological discomfort (t = 2.478, p = 0.014, d = 0.222), and psychological disability (t = 2.067, p = 0.039, d = 0.188).

CONCLUSION

This study found that the Chinese version of OHIP-14 has measurement invariance between the clinical and non-clinical populations and across genders in the clinical populations, and can be widely used in OHRQoL assessment for public oral investigations.
