The psychometric properties of a new oral health illness perception measure for adults aged 62 years and older

Evaluating conceptual model measurement and psychometric properties of Oral health-related quality of life instruments available for older adults: a systematic review

BACKGROUND

Older adults present a variety of oral diseases and conditions, in addition to co-morbidities and limited access to dental care, which significantly impact their oral health-related quality of life (OHRQoL). There are many instruments published to measure OHRQoL. However, it is challenging for clinicians and researchers to choose the best instrument for a given purpose.

PURPOSE

To identify OHRQoL instruments available for older adults and summarize the evidence on the conceptual and measurement model, psychometric properties, interpretability, and administration issues of OHRQoL instruments available for older adults through a systematic review.

METHODS

A systematic search was conducted in MEDLINE, EMBASE, LILACS, and CENTRAL up to February 2023. Articles reporting information on the concept model measurement, psychometric properties, and administration issues of an instrument measuring OHRQoL in older adults were included. Two researchers independently evaluated each instrument using the Evaluating Measures of Patient-Reported Outcomes (EMPRO) tool. The overall score and seven attribute-specific scores were calculated (range 0-100): Conceptual and measurement model, Reliability, Validity, Responsiveness, Interpretability, Burden, and Alternative forms.

RESULTS

We identified 14 instruments evaluated in 97 articles. The overall score varied between 73.7 and 8.9, with only six questionnaires over the threshold score 50.0. EORTC QLQ OH-15 (cancer-specific questionnaire) achieved the highest score (73.7), followed by OHIP (generic OHRQoL questionnaire) (66.9), GOHAI (generic OHRQoL questionnaire) (65.5), and OHIDL (generic OHRQoL questionnaire) (65.2). Overall, the Conceptual and measurement model and Validity showed the best performance, while Responsiveness and Interpretability showed the worst. Insufficient information was presented for an overall evaluation of DSQ and OHAI.

CONCLUSION

The evidence supports using EORTC QLQ-OH15 as a specific instrument to assess OHRQoL in cancer patients and the OHIP-49, GOHAI, or OHIDL as generic instruments to assess OHRQoL either for cross-sectional or longitudinal studies in older adults.

Psychometric Properties of the Brazilian Version of GOHAI among Community-Dwelling Elderly People

This study assessed the psychometric properties of the Brazilian version of the Geriatric Oral Health Assessment Index (GOHAI). A representative sample of 613 community-dwelling elderly people aged from 65 to 74 years was selected. Sociodemographic data, GOHAI and self-perceived oral health measures were collected. Dental clinical measures were obtained through oral examinations. The dimensional structure and adequacy of components were assessed using Confirmatory Factor Analysis (CFA), inter-item correlations and item-scale correlations. Reliability was evaluated by internal consistency and Intraclass Correlation Coefficients. Correlations between GOHAI scores and self-reported oral health measures were conducted to assess convergent validity. The relationship between dental clinical measures and GOHAI was tested through Poisson Regression to examine discriminant validity. The link between GOHAI items and dimensions was supported by CFA. Item 12 showed a poor factor loading. The inter-item correlations varied from 0.047 to 0.442, and item-scale correlations ranged from 0.305 to 0.612. Cronbach's alpha was 0.704. The test-retest correlation for GOHAI was 0.882. GOHAI scores were correlated by self-rated oral health measures. Poor dental clinical measures were associated with GOHAI. The Brazilian version of GOHAI showed adequate psychometric properties. However, the weak dimensional structure of GOHAI suggests the need to perform cross-cultural adaptation of GOHAI for Brazilian elderly people.

Developing a Multilevel Scale to Assess Retention of Workers with Disabilities

Purpose Persons with disabilities (PwD) face difficulties in employment. Despite extensive research on PwD in the workplace, there is lack of research on the factors behind retaining or terminating the job of a PwD. This study aims to address this gap by developing the Retaining Workers with Disability (RWD) model. Method Predicated on 1032 respondents with employment decision authority, we performed exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) for convergent and discriminant validity of the RWD model. Next, we developed the two-rank model RWD-II and employed CFA for validation. Results We presented a dual-facet measurement tool for assessing employer attitudes towards retaining PwD in the workplace. Two dominant factors were measured, direct and indirect work-related items. Indices for both models (one and two-rank) showed a good fit. Conclusion Our study highlighted two major factors influencing managers in the decision-making process of retaining workers with disabilities as follows: direct and indirect work-related concerns. The measure was validated using the RWD scale. By providing the tool to identify attitudes towards PwD work retention, we offer the first step in identifying and changing a negative approach toward this population in the workplace. Practical contributions are discussed.

Comparative Effectiveness of Two Nonsurgical Treatments to Reduce Oral Health Disparities From Untreated Tooth Decay in Older Adults: Protocol for a Cluster Randomized Trial

BACKGROUND

The majority of dental caries lesions in older adults are at the gumline, at the edges of failed fillings and crowns, and in the surfaces of roots after gum recession. These lesions are difficult to restore with conventional surgical treatments using a dental drill and restorations often fail. Clinical guidelines are general and apply treatments that were designed for younger individuals in the dental care of older adults.

OBJECTIVE

This study will compare the effectiveness of 2 evidence-based nonsurgical strategies to manage dental caries lesions in adults aged 62 or older: (1) biannual topical application of silver diamine fluoride versus (2) atraumatic restorative treatment + biannual fluoride varnish.

METHODS

A cluster randomized clinical trial is being conducted in 22 publicly subsidized and other low-income housing facilities/sites (Arm 1: 11 sites, 275 participants; Arm 2: 11 sites, 275 participants). At baseline, participants will be screened for caries lesions. Those with nonurgent lesions will be treated according to the treatment arm to which the housing site was randomly assigned. The primary outcomes are caries lesion arrest, tooth sensitivity, and tooth pain at 52 weeks after treatment. Analytic methods for the primary aim include a generalized estimating equation approach to determine noninferiority of silver diamine fluoride relative to atraumatic restorative treatment + fluoride varnish treatment.

RESULTS

The trial was funded in April 2019. Enrollment began in September 2019 and results are expected in June 2023.

CONCLUSIONS

This study will inform the standard of care for treating caries lesions in older adults. If effective, either of these interventions has broad applicability in clinical and community-based settings.

Psychometric evaluation of the illness perception questionnaire for schizophrenia in a Chinese population

BACKGROUND

Illness perceptions have been associated with patients' reactions to health threats and further health outcomes. The Illness Perception Questionnaire for Schizophrenia (IPQS)¹ has been applied in different contexts. However, the validity and reliability of IPQS remain unknown in mainland China.

AIMS AND OBJECTIVES

To test the psychometric properties of the Chinese version of IPQS in mainland China.

DESIGN

A cross-sectional survey.

METHODS

A total of 200 community-dwelling patients with schizophrenia were surveyed in Beijing, China. The validity and reliability of the instrument were tested. As well as demographic data, the IPQS and the Knowledge About Schizophrenia Test (KAST)² were also administered.

RESULTS

Factor analysis was utilised to refine the factor structure of the IPQS. The difference between IPQS and KAST denoted the discriminant validity. The subscale scores among patients of different illness duration, educational attainment, and medication adherence in the past two years were significantly different (P＜0.05), indicating the known-group validity of the IPQS. Except for 'personal control' and 'burdensome effect', other subscales were internally consistent. Most of the subscales proved stable over a four-week period.

CONCLUSION

The Chinese version of IPQS can be used, with some refinements, to assess illness perceptions about schizophrenia for patients in future studies. This will provide empirical evidence for its generalizability and clinical utility and provide deeper insight into Chinese patients' illness perceptions about schizophrenia.
