Acquisition and maintenance of dental anxiety: the role of conditioning experiences and cognitive factors.
This study presents a contribution to the understanding of the mechanisms that are involved in the development and maintenance of dental anxiety. Subjects were 224 undergraduate psychology students who completed questionnaires regarding dental anxiety, painful and traumatic experiences, negative cognitions, dental beliefs, and how their attitude to dental treatment had changed during their life. The results showed that both the extent to which earlier dental treatments were perceived as painful and the extent to which these incidents were reported as traumatic were significantly related to dental anxiety. Evidence was also found to support the latent inhibition hypothesis, which predicts that patients less easily acquire dental anxiety in case they received a number of relatively painless treatments prior to conditioning. Both findings confirmed those earlier obtained by Davey in a conceptually similar design (Behaviour Research and Therapy, 27, 51-58, 1989). In addition, frequency of negative cognitions about dental treatment and dental anxiety appeared to be positively related (r = 0.74; P < 0.001). Significant differences were found between highly anxious Ss and Ss showing low levels of anxiety on a variety of expectations and beliefs related to undergoing dental treatment. The results are discussed in terms of a cognitive-behavioural perspective of dental anxiety.
