Korean version of child perceptions questionnaire and dental caries among Korean children

Translation and validation of the French version of the child perceptions questionnaire for children aged 11 to 14 years old (CPQ11-14) short-form

OBJECTIVES

The COHQoL is a set of questionnaires used to evaluate the impact of oral health on children's quality of life. Although the CPQ8-10 and the P-CPQ have been translated and validated in French, the CPQ11-14 14 has not yet been validated. The aim was to develop a French version of the CPQ11-14 16-items.

MATERIALS AND METHODS

The French version of CPQ11-14 was obtained by a forward-backward translation process and pretested. The final version was tested on children aged 11-14 and divided into three groups: children with orofacial clefts, children with rare dental diseases other than clefts, and children without anomalies. We conducted a cross-sectional study and evaluated the reliability with test-retest and internal consistency, and the questionnaire validity with construct validity and discriminant validity. We performed an Exploratory Factory Analysis (EFA).

RESULTS

187 children tested the questionnaire. The ICC of the test-retest was 0.76 and the Cronbach's alpha was 0.77. The correlation between the CPQ11-14 and self-assessment of oral health and general well-being was > 0.2. Patients with orofacial clefts and rare diseases had significantly higher scores for overall short-form CPQ11-14. The EFA revealed six factors.

CONCLUSION

The French CPQ11-14 is valid to assess the impact of oral health on children's quality of life.

CLINICAL RELEVANCE

The translation of this questionnaire into French will enable us to assess the impact of oral health on the quality of life of adolescents. This questionnaire complements the 8-10 years version of the CPQ, as well as the parental version that can be used in conjunction with the questionnaire.

Oral Health-Related Quality of Life in Persian-Speaking Elementary Schoolers in Iran: A Psychometric Study of Child Perception Questionnaire

Background and Purpose: The study aims to examine the validity and reliability of the impact of 16-item Short-Form Child Perception Questionnaire (CPQ11-14-ISF:16) in Persian-speaking elementary schoolers. Methods: From two main cities in Iran, 708 mother-child dyads were enrolled in 2018. Decayed, missing, and filled teeth (DMFT/dmft) indexes were examined for divergent validity. Two built-in indexes of overall oral health and overall impacted well-being were used for concurrent validity. Exploratory factor analysis (EFA) with Geomin rotation, Cronbach's α, and Spearman's correlation were executed. Results: The total Cronbach's α was 0.71. EFA indicated CPQ11-14-ISF:11 (α = 0.66) to compose three eligible factors (α = 0.66), including oral problems (α = 0.54), emotional problems (α = 0.66), and social problems (α = 0.41). The concurrent/divergent validity of CPQ11-14-ISF:11 and the subscales was partially confirmed. Conclusions: The use of CPQ11-14-ISF:11 to multidimensionally address dental care for children requires further investigations.

Validity and reliability of the Turkish version of the Child Perceptions Questionnaire 8-10

BACKGROUND

A reliable measurement tool is needed to gain more knowledge about Turkish children's oral health status that affects the quality of life.

AIM

To develop a translated version of CPQ_8-10 into Turkish language and evaluate its reliability, validity, and reproducibility.

DESIGN

The intra-class correlation coefficient (ICC) was used for the test-retest reliability in the 50 children. For the internal consistency, 418 children aged 8-10 years were evaluated using Cronbach's alpha Coefficient. Construct validity and discriminant validity were calculated using Spearman's correlation analysis, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was also employed.

RESULTS

The mean CPQ_8-10 score was 13.3 ± 9.2. The translated Turkish version of CPQ_8-10 showed high test-retest reliability (ICC = 0.90) and internal consistency (Cronbach's alpha = 0.82). A statistically significant correlation was observed between the scores of the CPQ_8-10 and oral health and overall well-being, which revealed good construct validity (r = 0.50; P < .001 and r = 0.47; P < .001, respectively). Seven factors identified from EFA were statistically verified using CFA. Discriminant validity was supported by significant differences between CPQ and OHIS scores (P < .001).

CONCLUSIONS

The translated version of CPQ_8-10 to the Turkish language is reliable, valid, and reproducible for use in the Turkish culture in this age group.

Influence of caries and molar incisor hypomineralization on oral health-related quality of life in children

OBJECTIVES

This study was aimed to compare the impact of caries and molar incisor hypomineralization (MIH) on oral health-related quality of life (OHRQoL) in children.

MATERIAL AND METHODS

A total of 528 German children aged 7 to 10 years were recruited, half affected by caries and the other half affected by MIH. Both groups were matched according to age, sex, and social status and divided into 3 categories according to severity. The German version of the Child Perceptions Questionnaire for 8- to 10 years old (CPQ-G8-10) was used to analyze the impact on OHRQoL by applying ANOVA models.

RESULTS

Patients with MIH showed a mean CPQ score of 10.7 (± 9.3). This was significantly higher compared to the caries group with 8.1 (± 9.8). The score increased linearly from the low severity category to the high severity category in both groups (caries, 4.1 to 13.8; MIH, 5.2 to 17.7, respectively).

CONCLUSION

With increasing severity, both clinical conditions showed a greater negative impact on OHRQoL. MIH was associated with more impairments.

CLINICAL RELEVANCE

Currently, the focus in pediatric dentistry is placed on the prevention and treatment of caries. Both diseases may have a negative influence on OHRQoL. Since children perceive the impairments by MIH as worse and the prevalence is equal to that of caries, which focus might be shifted in the future.

Cross-cultural adaptation and psychometric properties of the Hindi version of Child Perception Questionnaire (CPQ11-14 ) in school children

BACKGROUND

There is a need to validate OHRQoL measures in Hindi to assess the OHRQoL of Indian children.

AIM

To develop a Hindi version of the CPQ_11-14 and to appraise its validity and reliability for use among North Indian children aged 11-14 years.

DESIGN

The cross-culturally adapted Hindi version of CPQ_11-14 was achieved by forward translation, backward translation, committee review, and pretesting. A total of 1000 children were recruited from schools, chosen by two-stage cluster random sampling technique. After completing the self-administered questionnaire CPQ_11-14 by the child, oral examination was conducted using decayed/missing/filled teeth (DMFT) index, malocclusion index, and Dean's fluorosis index. Test-retest reliability was checked on 100 participants after one week.

RESULTS

The floor effect was present in 3.6% individuals, and there was no ceiling effect. Cronbach's alpha for the overall CPQ_11-14 scale was 0.963. Intra-class correlation (ICC) coefficient was 0.952 for the entire scale. Cronbach's alpha value for test-retest was 0.918. There was a non-significant change in domain-level and overall median CPQ_11-14 scores with an increase in DMFT scores. For malocclusion and fluorosis, there was a statistically significant increase in overall and domain-level scores with increased severity scores. CPQ_11-14 and individual domains significantly correlated with both the global questions.

CONCLUSION

Hindi version of CPQ_11-14 is a reliable scale to assess OHRQoL in Hindi speaking 11- to 14-year-old children.

Validity and reliability of the Child Perceptions Questionnaire 11-14 for Colombian school children

PURPOSE

To evaluate the validity and reliability of the Child Perceptions Questionnaire 11-14 (CPQ11-14) for children attending public educational institutions in Floridablanca (Colombia).

METHODS

An evaluation study of diagnostic technology was conducted. The questionnaire was completed by 500 students aged 11-14 years who were selected by simple random sampling. The test-retest reproducibility was evaluated in 36 students chosen at random from one of the schools; the questionnaire was completed a second time by these students, with an interval of two weeks between administrations. Internal consistency was estimated using the Cronbach's alpha coefficient, and test-retest reproducibility was determined with the intraclass correlation coefficient (ICC). The Rasch Rating Scale Model was used to perform the validation; the structure of the categories, the quality of the items, the invariance and the one-dimensionality were analyzed; invariance was confirmed using differential item functioning (DIF). Informed consent was obtained from the parents or guardians, and assent was obtained from the minors.

RESULTS

The mean age was 12.7 ± 1.1 years, and 210 (42.0%) participants were female. The Cronbach's alpha and ICC values were 0.91 and 0.63, respectively. The 37 items fit the Rasch model, but a uniform DIF was observed for an item that was eliminated. The questionnaire was not one-dimensional, and the proportion of variance explained by the model was poor (26.3%).

CONCLUSION

The CPQ11-14 showed unsatisfactory test-retest reproducibility and excellent internal consistency; no unidimensionality was observed, but the items fit the Rasch model.

Validity and reliability of the Arabic version of the child perceptions questionnaire for 8-10-year-old children

Purpose

To develop an Arabic version of the CPQ_8–10 and test its validity and reliability for use among Arabic-speaking children.

Methods

The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8–10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test–retest reliability were assessed using Spearman’s rank correlation coefficients, Cronbach’s alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed.

Results

CPQ_8–10 scores and global ratings were positively correlated. CPQ_8–10 scores were highest in group II, followed by groups I and III, respectively. CPQ_8–10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach’s alpha was 0.95 and the intraclass correlation coefficient was 0.97.

Conclusions

The Arabic CPQ_8–10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.

Relationships of Dental Caries and Malocclusion with Oral Health-Related Quality of Life in Lithuanian Adolescents Aged 15 to 18 Years: A Cross-Sectional Study

There is a lack of evidence of the moderating effects of caries lesions and malocclusions on oral health-related quality of life (OHRQoL) among older adolescents. This study aimed to evaluate the relationship of dental caries and malocclusion with OHRQoL among Lithuanian adolescents aged 15 to 18 years. A survey in a representative sample of adolescents included a clinical examination to assess dental health status using the DMFT (Decayed, Missing, and Filled Permanent Teeth) index, and malocclusion using the Index of Complexity, Outcome, and Need (ICON). The Child Perceptions Questionnaire (CPQ) was used to evaluate respondents’ OHRQoL. Negative binomial regression was fitted to associate the clinical variables with the CPQ scores. A total of 600 adolescents were examined. The overall mean DMFT score was 2.7. A need for orthodontic treatment was detected among 27.7% of adolescents. Subjects with caries lesions (DMFT > 3) had higher CPQ scores in the domains of functional limitations and social wellbeing (relative risks were 1.35 (95% confidence interval: 1.09–1.67) and 1.30 (1.03–1.64), respectively), while subjects with a need for orthodontic treatment (ICON > 43) had higher CPQ scores in the domains of emotional wellbeing and social wellbeing (relative risks were 1.81 (1.40–2.22), and 1.69 (1.34–2.14), respectively). It was concluded that both dental caries and malocclusion have negative relationships with OHRQoL in adolescents above 15 years, but their effects occur differently in each OHRQoL domain.

Validity and reliability of the Swedish versions of the short-form Child Perceptions Questionnaire 11-14 and Parental Perceptions Questionnaire

Objective: To examine the validity and reliability of the Swedish versions of the short-form Child Perceptions Questionnaire 11-14 (CPQ_11-14) and Parental Perceptions Questionnaire (P-CPQ) for measuring children's oral health-related quality of life (OHRQoL). Material and methods: The sample comprised 247 children and parents. OHRQoL was assessed by asking each child and their accompanying parent to complete the relevant questionnaire. To allow test-retest analysis, 30 children and 32 parents were asked to complete the instrument a second time within 2-4 weeks. Results: In terms of construct validity, significant correlations were observed between CPQ scale scores and the global ratings of oral health and overall well-being for both the CPQ_11-14 and the P-CPQ. Regarding internal consistency, Cronbach's alphas for the total scales were 0.81 and 0.77, respectively, indicating good reliability, and internal consistency for the subscales (two or four dimensions) was acceptable. Test-retest reliability was good for the CPQ_11-14 total scale (ICC 0.77) and acceptable for the P-CPQ total scale (ICC 0.63). Conclusions: The Swedish versions of the short-form CPQ_11-14 and P-CPQ are both valid and reliable, and can be recommended for use among Swedish children aged 11-14 years for evaluation of OHRQoL.

Modification and psychometric evaluation of the child perceptions questionnaire (CPQ11-14) in assessing oral health related quality of life among Lithuanian children

Background

Oral health related quality of life (OHRQoL) research among children and adolescents in Lithuania is just starting and no measures have been validated to date. Therefore, this study aimed to validate a Lithuanian version of the full (37 items) Child Perceptions Questionnaire (CPQ_11–14) within a random sample of children aged 11 to 14.

Methods

A cross-sectional survey among a randomly selected sample of schoolchildren (N = 307) aged 11 to14 was conducted. An anonymous questionnaire included the full CPQ_11–14 and items on global life satisfaction, oral health and oral life quality self-rating. The questionnaire was translated into Lithuanian using translation guidelines. In addition, an item on the oral pain was modified identifying the pain location. Standard tests (Cronbach’s α, construct validity and discriminant validity), supplemented with both exploratory and confirmatory factor analyses, were employed for psychometric evaluation of the instrument. The questionnaire was also tested by comparison students’ and their parents’ (N = 255) responses about oral symptoms and functional limitations.

Results

The modified Lithuanian version of CPQ_11–14 revealed good internal consistency reliability (Cronbach’s alpha for the total scale was 0.88). The measure showed significant associations with perceived oral health status and oral well-being, as well as with global life satisfaction (p < 0.01). Discriminant validity of the instrument was approved by comparison of children’s groups defined by self-reported caries experience and malocclusion. Factor analysis revealed a complex structure with two or three factors in each of four domains of the CPQ_11–14. Excellent or acceptable levels of indices of model fitting with the given data were obtained for oral symptoms, functional limitations and emotional well-being domains, but not for the social well-being domain. A significant association between child and parental responses was found (intraclass correlation coefficient was 0.56 and 0.43, correspondingly in domains of oral symptoms and functional limitations).

Conclusion

The Lithuanian version of the CPQ_11–14 (with a modified item that identifies location of oral pain) appears to be a valid instrument to be used in further studies for measuring OHRQoL among 11 to 14 year old children in Lithuania.

Translation and validation of the French version of the Child Perceptions Questionnaire for children aged from 8 to 10 years old (CPQ 8-10)

BACKGROUND

The Child Perceptions Questionnaire (CPQ) belongs to a set of questionnaires measuring Child Oral Health Quality of Life (COHQOL). The CPQ is used to collect the perceptions of children on the impact of oral diseases on their quality of life. This cross-sectional study was aimed to translate the CPQ_8-10 into French language and evaluate its psychometric properties.

METHODS

The translation process complied with international recommendations. The final French version was tested on children aged 8-10 years old attending consultations in a Parisian public hospital and divided into three groups: children with oral-facial clefts, children with dental anomalies linked to a rare disease other than clefts and children presumed to be healthy and without anomalies. The internal consistency relating to the reliability of CPQ_8-10 was evaluated by Cronbach's alpha. The intra-class correlation was used to measure reproducibility at the test-retest level. Construct validity was evaluated by Spearman's correlation and tested using factor analysis. The discriminant validity was assessed using Kruskall Wallis test. Criterion validity was calculated using Spearman's correlation.

RESULTS

One hundred seventy-six children participated in this study. During the translation process, minor changes were made. The French version showed good reliability with a Cronbach's alpha of 0.81 for the total scale. The ICC of the test-retest was excellent (=0.90) demonstrating good reproducibility. The construct validity was acceptable with a statistically significant correlation between the scores of the French-CPQ_8-10 and the evaluation of oral health (r = 0. 381 and p < 0.001) and its impact on oral health quality of life (r = 0.363 and p < 0.001). The loading weights obtained in the Exploratory Factor Analysis showed that this model revealed seven factors with eigenvalue greater than 1, explaining the 63,89% of the cumulative variance. The differences observed between the scores of the study groups revealed good discriminant validity. Criterion validity was supported by significant association between CPQ scores and pain.

CONCLUSION

The French-CPQ_8-10 is reliable and valid for use with the children of this age group.

Psychometric Properties of Translation of the Child Perception Questionnaire (CPQ11-14) in Telugu Speaking Indian Children

Oral health related quality of life research among children in India is still nascent and no measures have been validated to date. Although CPQ_11-14 has been previously used in studies from the Indian sub-continent, the instrument has never been tested for cross-cultural adaptability. This study aimed to assess the validity and reliability of CPQ_11-14 in Telugu speaking Indian school children. Primary school children of Medak district, Telangana State, India, were recruited by a multi-stage probability sampling method. The translated questionnaire was initially pilot tested on a small subset of children (n = 40). Children with informed consent from parents (N = 1342) were then provided with questionnaires containing the Telugu translation of CPQ_11-14, followed by a clinical examination conducted by a single examiner, using Basic WHO survey methods for dental caries, malocclusion, and Dean’s Fluorosis index. Children (n = 161) in randomly chosen schools were re-administered the same questionnaire after a two week interval to test reliability of CPQ_11-14 on repeated administrations. Internal consistency and test-retest reliability as determined by Cronbach’s alpha and Intra-class correlation coefficient for overall CPQ_11-14 scale were 0.925 and 0.923, respectively. CPQ_11-14 discriminated between the categories of fluorosis and malocclusion while its discriminant validity with respect to dental caries was limited. CPQ_11-14 also demonstrated good construct validity with both overall CPQ_11-14 and its subscales having significant positive correlation with global ratings of oral health and overall wellbeing, even after adjusting for confounding variables. CPQ_11-14 had a correlation of 0.405 with self-evaluated oral health and 0.407 with self-evaluated impact of oral health on overall wellbeing. In conclusion, Telugu translation of CPQ_11-14 demonstrated good internal consistency and excellent reliability on repeated administrations after two weeks. It also exhibited good discriminant and construct validity.
