The effect of caries increment on oral health-related quality of life among adolescents in Brazil: a 3-year longitudinal study

Abstract

This study aimed to assess the effect of caries increment on Oral Health-related Quality of Life (OHRQoL) of Brazilian adolescents and to evaluate the responsiveness of the Child Perceptions Questionnaire (CPQ 11-14) in this group. A population-based sample of 515 Brazilian 12-year-olds from a large city located in the southeast of Brazil was evaluated according to a random multistage sampling design at baseline and 291 at three years follow-up, using the DMFT index and the CPQ 11-14 instrument. To evaluate the responsiveness to change, the measures of effect size and longitudinal construct validity were used. It was verified that OHRQoL among adolescents with DMFT increment across the three years worsened significantly (p<0.05) in relation to their counterparts. The effect size varied from small to moderate. The longitudinal construct validity of CPQ 11-14 was satisfactory. Caries increment impacted on OHRQoL of adolescents in Brazil. The CPQ 11-14 instrument demonstrated acceptable responsiveness properties.

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

“…Studies conducted in China [62], Hong Kong [63,64] and India [65] also reported similar associations. Furthermore, the number of decayed and missing teeth [5], caries increment [66] and PUFA/pufa [67] were associated with higher Child Perception Questionnaire (CPQ 8-10 and CPQ [11][12][13][14] scores among children in Brazil and Egypt [68], and higher Child-Oral Impact on Daily Performance (Child-OIDP) scores among children in Thailand [69][70][71] and India [72].…”

Impact of dental treatment on the oral health-related quality of life of Brazilian schoolchildren

“…[6][7][8][9][10][11][12] Many of these questionnaires have been tested for validity and reliability, but not for responsiveness and sensitivity, which are essential characteristics that demonstrate an instrument's ability to validly determine change over time. [13][14][15][16][17] It should also be pointed out that none of these questionnaires have been validated for use in children aged 6 to 7 years.…”
