Motivation and anxiety for dental treatment: Testing a self-determination theory model of oral self-care behaviour and dental clinic attendance

The present study: (1) developed a Self-Regulation Questionnaire for Dental Treatment (SRQDT) based on Self-Determination Theory (SDT; Deci and Ryan, Psychol Inq 11:227–268, 2000), and (2) used it to test a SDT process model of oral self-care behaviours and dental clinic attendance. Patients’ perceptions of autonomy supportive (relative to controlling) dental professionals were expected to be positively associated with patients’ psychological needs satisfaction in treatment, which was expected to be positively related to relative autonomous motivation for dental treatment and perceived dental competence, and negatively related to anxiety for dental treatment. In turn, relative autonomous motivation for dental treatment and perceived dental competence were expected to be positively associated with oral self-care behaviours and dental clinic attendance. Anxiety for dental treatment was expected to be negatively related to dental clinic attendance and positively linked to putting off making a dental clinic appointment. Confirmatory factor analysis of the 5 factor SRQDT model fit the data very well, and a structural equation model supported the hypothesized process model.
