Objective: To cross-adapt the Self-Regulation forDental Home Care Questionnaire (SRDHCQ) to the Indonesian version, and to study self-regulation for dentalhome care among adolescents. Methods: The SRDHCQ was cross culturally adapted to the Indonesian adolescentsaged 12-13 years old to test its reliability and validity. Intraoral examination was conducted by a single examiner toanalyse the number of decayed teeth. The SRDHCQ contains 22 questions with a 7-point scale, which comprisesof integrated, identified, introjected, external regulation and amotivation domains. Respondents were randomlyselected from 11 junior high schools at six districts in Jakarta. Results: Total respondents studied were 317 students,with prevalence of 71% of the students having decayed teeth, and average number decayed teeth was 2.1. The testand test-retest reliability and Cronbach’s alpha for internal consistency were 0.838 and 0.929, respectively. Nosignificant difference was observed in total SRDHCQ scores between genders. Constr uct and discriminant validityanalysis showed significant results. Conclusions: Our results support the reliability and validity of the IndonesianSRDHCQ for adolescents in Indonesia.
