Cross-cultural adaptation and psychometric properties of the Indonesian version of theory of planned behavior questionnaire to measure dental attendance of children with hearing loss: A pilot study

Aims: To translate and evaluate the validity and reliability of the Indonesian version of the Theory of Planned Behavior (TPB) questionnaire concerning mother's behavior related to children's dental attendance. Methods and results: The cross-cultural adaptation was tested in mothers with children aged 5–12 years old who have hearing loss. The validity and reliability of the online questionnaire were measured among 31 mothers of children with hearing loss in communities and Special School for Children with Hearing Loss in several regions in Indonesia. All indicators of attitude, subjective norms, and perceived behavior control (PBC) on mothers’ behavior towards children's attendance was valid (p <.05). The overall Cronbach's alpha of the questionnaire for internal consistency was 0.773. The test-retest reliability results were based on repeated administration in the same participant mother, measured at one-week interval; the interclass correlation coefficient (ICC) was 0.903. Conclusion: The Indonesian version of the TPB questionnaire concerning mother's behavior related to children's oral health has shown adequate validity and reliability for investigating the dental attendance of children with hearing loss.
