Cross cultural adaptation and psychometric properties of the Bengali version of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5)

Psychometric properties of the Thai version of the Scale of Oral Health Outcomes for 5-year-old children

BACKGROUND

As caries prevalence in Thai preschool children is very high and its consequences have scarcely been evaluated, the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) is considered as an appropriate tool to measure the children's oral health-related quality of life (OHRQoL).

AIM

To translate the SOHO-5 into Thai (Th-SOHO-5) and assess its psychometric characteristics.

DESIGN

The cross-cultural adaptation of the SOHO-5 into Thai comprised forward-backward translation by experts and face validation by 20 child-parent dyads. To evaluate psychometric properties of the final version, a cross-sectional study was conducted on 306 child-parent pairs using an interview mode for children and a self-administered mode for parents. A trained investigator examined children's caries status.

RESULTS

The Th-SOHO-5 showed satisfactory psychometric characteristics. Cronbach's alpha values were above 0.8 for both child and proxy reports. Overall intraclass correlation coefficients were > 0.9. Factor analysis supported a single-factor structure model of the Th-SOHO-5 and showed an excellent fit. Th-SOHO-5 scores were correlated with all global rating scales of oral health and well-being. Children with higher caries experience or caries with pulpal involvement demonstrated significantly higher Th-SOHO-5 scores.

CONCLUSION

The Th-SOHO-5 possessed good reliability and validity. It can be used to evaluate the OHRQoL of preschool children in Thailand.

Cross-cultural adaptation and psychometric properties of the Myanmar version of the scale of oral health outcomes for 5-year-old children

OBJECTIVE

The aim of this study was to cross-culturally adapt the child's self-report and parental report of the scale of oral health outcomes for 5-year-old children (SOHO-5) for use in Myanmar (Burmese-speaking) population and to assess the reliability and validity of the Myanmar version.

MATERIALS AND METHODS

The forward-backward translation method was used to develop the Myanmar SOHO-5 version and the final questionnaires were tested on 173 five years old children and their parents for reliability and validity. A single dentist examined the caries experience of the children (Kappa:0.90). The structural validity was assessed through confirmatory factor analysis. The internal consistency and test-retest reliability (1-2 weeks) were evaluated using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. The association between SOHO-5 scores and additional global rating questions for child oral health status (convergent validity) and the differences between the total SOHO-5 score of children with caries and children without caries (discriminant validity) were investigated.

RESULTS

A confirmatory factor analysis indicated a good fit for the one-factor structure of the SOHO-5. Cronbach's alpha coefficient values for internal consistency were 0.82 for the children's report and 0.79 for the parental report. The ICCs were 0.90 and 0.89 for the total scores of the children and parental versions in the test-retest reliability analysis. The total SOHO-5 scores for both reports were significantly associated with the global rating questions except for the 'impact on children's general health' question in the parental report. Furthermore, the Myanmar version discriminated between the children with and without caries experiences (p < 0.001).

CONCLUSION

This study provided evidence that both children and parental reports of the Myanmar SOHO-5 version have good reliability and validity to assess the OHRQoL of 5-year-old children in a Burmese-speaking population.

The role of oral health-related quality of life in the association between dental caries and height, weight and BMI among children in Bangladesh

OBJECTIVES

To examine whether oral health-related quality of life (OHRQoL) explained the negative associations between dental caries and anthropometric measures of child growth among a sample of 5- to 9-year-old children in Dhaka, Bangladesh, while taking potential confounding factors (maternal education, family income, study setting, child's birth weight and childhood diseases) into account. In addition, to test whether specific oral impacts had a role in explaining these associations.

METHODS

Data collection was conducted via a cross-sectional survey among children and their parents from both hospital and school settings in Dhaka. Dental caries and severe consequences of dental caries (defined here as dental sepsis) were the exposure variables, and age- and sex-adjusted height-z-scores (HAZ), weight-z-scores (WAZ) and BMI-z-scores (BAZ) were the outcome variables. OHRQoL was measured using the Bengali version of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5). First, associations between oral impacts (prevalence of overall impacts and specific items of the SOHO-5) and outcome measures were assessed. Multiple linear regression was used to assess associations between caries and anthropometric measures, adjusted for potential confounders. Oral impacts were then added to test whether their inclusion attenuated the associations between exposures and outcomes. To further investigate potential mediating role of oral impacts, structural equation modelling (SEM) was used to test the hypothesis that dental caries and sepsis were associated with the outcomes directly and also indirectly via oral impacts in general. A similar approach was used to investigate mediation by specific SOHO-5 items.

RESULTS

The sample consisted of 715 children, 73.1% of whom had dental caries, 37.5% presented with sepsis, and 57.3% reported at least one oral impact (SOHO-5 score ≥1). Prevalence of overall oral impacts and also the impact on 'eating difficulty' (a specific item of SOHO-5) were negatively associated with all three outcomes. Dental caries and sepsis was associated with lower HAZ, WAZ and BAZ, and adjustment for overall oral impacts considerably attenuated the associations between 'severe dental caries' and outcomes, and dental sepsis and outcomes. Using SEM, we found significant indirect associations between caries and sepsis and anthropometric measures via oral impacts (except for dental caries and HAZ). Considering specific oral impacts, eating difficulties explained about 44% and 65% of the associations between caries and anthropometric outcomes, and dental sepsis and anthropometric outcomes, respectively.

CONCLUSIONS

Oral impacts, in particular eating difficulties, appear to mediate associations between caries and markers of child growth among this population.

Serious health-related suffering experienced by children with disability and their families living in Bangladesh: A scoping review

BACKGROUND

In 2020, the International Association for Hospice and Palliative Care redefined palliative care to incorporate the concept of serious health-related suffering. An estimated 21 million children globally live with conditions which would benefit from a palliative approach to relieve suffering. Bangladesh is a lower-middle income country with isolated provision of palliative care.

AIM

To synthesise existing evidence describing serious health-related suffering of children with disability and their families living in Bangladesh and the intersection between this suffering, palliative care and rehabilitation.

DESIGN

Scoping review methodology.

DATA SOURCES

A search strategy related to serious health-related suffering and childhood disability was applied to online databases and grey literature. English language studies (1990-2021) were included. Papers pertaining to serious health-related suffering of typically developing children and those over eighteen years were excluded. Data which addressed the three domains of serious health-related suffering (physical, social and emotional/spiritual) were extracted. Palliative care interventions were assessed with a pre-existing checklist.

RESULTS

Forty-six studies were included, representing ten different methodologies. Sample sizes ranged from 11 to 2582 participants, with 87% of studies including children with cerebral palsy. Serious health-related suffering was described in 100% of the studies, only 14 of the studies described specific interventions to mitigate suffering. Convergence between palliative care and rehabilitation approaches was evident.

CONCLUSION

Findings document the extensive nature and burden of serious childhood health-related suffering that may be remediated by a palliative approach. They highlight the urgent need to prioritise service development and research in this area.

Quality of the adaptation procedures and psychometric properties of the scale of oral health outcomes for 5-year-old children (SOHO-5): a systematic review

PURPOSE

The aim of this study was to assess the quality of the cross-cultural adaptations and psychometric properties of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5).

METHODS

A systematic search was performed in three databases, PubMed, SCOPUS, and Dentistry and Oral Science Source (EBSCO). Studies relating to the cross-cultural adaptation and psychometric properties of SOHO-5 were included. The quality of cross-cultural adaptation was assessed in five aspects including translation, synthesis, back-translation, expert committee review, and pretesting. The Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist was used to assess the psychometric properties in seven domains including responsiveness, internal consistency, reliability, measurement error, and structural, construct, and cross-cultural validity.

RESULTS

The search identified 162 papers for screening; from these, 107 articles and 9 systematic reviews were excluded. 21 full papers were retrieved and 6 studies that met the inclusion criteria were included. Out of six, two reported all five aspects of cross-cultural adaptation procedures. Regarding the psychometric properties, none of the studies evaluated all aspects of psychometric properties. Almost all of the studies reported internal consistency (Cronbach's alpha ranging from 0.71 to 0.90), test-retest reliability (Intraclass Correlation Coefficient 0.46-0.98), and construct validity. None reported the cross-cultural validity and responsiveness of the measures.

CONCLUSION

While these studies provided satisfactory results regarding the validity and reliability of SOHO-5, the majority of the included studies did not report all domains of the cross-cultural adaptations and psychometric properties. Overall, the quality of the cross-cultural adaptations and psychometric properties of the included studies is doubtful. Future research should follow the guidelines to assess all aspects of psychometric properties and adaptation procedures in cross-cultural settings.
