Motivation for Dental Home Care: Testing a Self‐Determination Theory Model¹

The present research developed the Self‐Regulation for Dental Home Care Questionnaire (SRDHCQ), based on self‐determination theory (SDT; Deci & Ryan, 2000 ), and used it in an SDT process model of dental health behaviors and self‐rated oral health. In this model, patients' perceptions of autonomy‐supportive (relative to controlling) dental professionals were expected to positively predict patients' psychological needs satisfaction in treatment. Needs satisfaction was expected to be positively related to autonomous motivation for dental home care and perceived dental competence, which were expected to be positively associated with self‐rated oral health and dental health behaviors. Confirmatory factor analysis of the 5‐factor SRDHCQ model fit the data very well, and a structural equation model supported the hypothesized process model.
