Cross-cultural adaptation and validation of the Self-efficacy Scale to Brush Teeth at Night

Abstract

This study aims to perform cross-cultural adaptation and validation of the “Self-efficacy scale to brush teeth at night” with a Brazilian adult population. Translation and cross-cultural adaptation to the Brazilian-Portuguese language were done according to the stages recommended in the literature. Construct validity was carried out by mean of exploratory and confirmatory factorial analysis in a sample of 198 adult subjects. The reliability of the instrument was measured by Alpha and Omega indices. The model was observed to have been established as one-dimensional for all indicators, with explained variance of 85.7%; factorial loads between 0.85 and 0.91; and with communalities between 0.72 and 0.83. The goodness of fit of the model shown by the confirmatory model were between 0.98 and 0.99; with factorial loads between 0.85 and 0.93, and regression values between 0.69 and 0.84, all above the minimum indices established for instrument quality. For reliability, the Alpha and Omega values had identical indices of 0.95 showing high levels of reliability of the model. The G-H index replicability was 0.96, indicating the stability of solution in other contexts and samples. We concluded that all indicators represented excellent evidence of scale validity to measure self-efficacy to brush teeth at night.

Avaliação da qualidade de vida relacionada a saúde bucal e de uma intervenção motivacional breve nos comportamentos e condições bucais de usuários em Centros de Atenção Psicossocial - CAPS

“…To our knowledge, this is the first study that evaluated associations between oral outcomes and OHRQoL measured by OHIP-14 in a large sample of outpatient psychiatric patients in Brazil, since the published one included samples varying between 41 to 230 individuals and coming from only one PMHOC [19][20][21]. At international level, the only three studies published to date that evaluated the impact of oral health conditions on OHIP-14 scores with outpatient psychiatric population were done in Italy, England and Sweden using non-probabilistic samples with 67, 89 and 113…”

“…A autoeficácia para escovação noturna foi avaliada por meio de um instrumento que apresenta seis situações para escovação, cada uma com possibilidades de respostas variando entre 0 (nada capaz) a 4 (totalmente capaz). Os escores finais variam entre 0 a 24, sendo que escores mais altos indicam alto nível de autoeficácia na realização de escovação dental noturna (Bado et al, 2019).…”
