Validity and reliability of Child Perception Questionnaire (CPQ 11–14 ) by Rasch Analysis in Turkish children

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 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.

Extraversion and openness to experience moderate the relationship between orthodontic treatment need and oral health-related quality of life in adolescents: A cross-sectional study

OBJECTIVE

To investigate the effects of personality traits to moderate the relationships between orthodontic treatment need and oral health-related quality of life (OHRQoL) in adolescents.

MATERIALS AND METHODS

A cross-sectional study was performed that included 230 subjects (125 girls and 105 boys) aged 11-14 years. Orthodontic treatment need was measured using the Index of Complexity, Outcome and Need (ICON). The Child Perceptions Questionnaire, the Basic Personality Traits Inventory (BPTI), and the Revised Life Orientation Test were used to assess the OHRQoL, basic personality dimensions, and dispositional optimism respectively. Potential moderation effects were evaluated with Spearman's correlations and multiple regression analyses.

RESULTS

There were weak correlations between orthodontic treatment need and quality of life with social and emotional well-being dimensions ( r = 0.238, r = 0.296 and r = 0.209). A moderating effect of extraversion was observed in the relationship between orthodontic treatment need and OHRQoL, emotional well-being, and social well-being (SWB) (Δ R² = 0.03, Δ R² = 0.02, and Δ R² = 0.04, respectively). Openness to experience affected relationships between orthodontic treatment need and OHRQoL, and emotional well-being (EWB) (Δ R² = 0.03 and Δ R² = 0.04, respectively). In children with higher extraversion, the increase in ICON scores resulted in less increase in CPQ total, EWB, and SWB scores. In children with higher openness to experience, the increase influenced CPQ total and EWB scores similarly.

CONCLUSIONS

The relationship between orthodontic treatment need and quality of life is moderated by personality traits. Early adolescents with higher extraversion and openness to experience are less affected by increased orthodontic treatment need.
