Design outcomes

Primary

Measure	Time frame
- DAS score (trait anxiety of dental treatment: Dental Anxiety Scale) - Interpretive bias will be measured by the recognition task. In the first part of the measurement, 10 ambiguous dental situations will be presented to the participant. Each situation is followed by a neutral question about the situation. A correct answer indicates that the story has been read correctly. In the second part, the (biased) memory of the ambiguous situation is tested. The participant receives one positive and one negative interpretation of each story. Then, the participant is asked to rate these interpretations to what extent they match the story. If the participant rates the negative interpretations as more matching to the ambiguous story, this is considered a negative interpretation bias. The level of positive or negative interpretation bias can be calculated by adding up the scores for positive and negative interpretations respectively.	—

Secondary

Measure	Time frame
- DPFR score (anticipation anxiety of dental treatment: the duration of psychophysiological reactions). - K-ATB score (trait anxiety of dental treatment: the short version of the Dental Anxiety Inventory) - AS-score (Visual analogue scale that indicates the overall anxiety level of dental treatment) - The number of drop-out during the research (specifically: after which time during a CBM-I session and at which CBM-I session). - Reason for drop-out.	—
