Just let me check: The role of individual differences in self-reported anxiety and obsessive-compulsive features on subjective, behavioural, and physiological indices during a checking task

Checking behaviour has been described as a form of preventative behaviour used by an individual to establish control over the environment and avoid future misfortune. However, when compulsive, checking behaviours can become disabling and distressing and have been linked to the maintenance of anxiety and obsessive-compulsive disorders. Despite this, there is limited literature across the field that has assessed the impact of dimensional measures of anxiety and obsessive-compulsive features (i.e., negative affect, uncertainty, and perfectionism) in driving checking behaviour. As such, the present study examined the impact of individual differences in self -reported anxiety and obsessive-compulsive features on subjective, behavioural, and physiological indices dur-ing a visual discrimination and checking task (n = 87). Higher self-reported anxiety and obsessive-compulsive features were associated with higher subjective ratings of unpleasantness and the urge to check during the task. Moreover, higher self-reported anxiety and obsessive-compulsive features related to general negative affect, uncertainty, and perfectionism were associated with greater checking frequency during the task. Lastly, stronger obsessional beliefs about perfectionism and the need for certainty were found to predict poorer accuracy, slower reaction times, and higher engagement of the corrugator supercilii during the task. In sum, these findings demonstrate how different anxiety and obsessive-compulsive features, in particular perfectionism and the need for certainty, may relate to and maintain checking behaviour in low threat contexts, which likely has implica-tions for models of excessive and persistent checking in anxiety and obsessive-compulsive disorders.

Automated summary

This study examined the impact of individual differences in self-reported anxiety and obsessive-compulsive features on subjective, behavioral, and physiological indices during a visual discrimination and checking task. The results showed that higher self-reported anxiety and obsessive-compulsive features were associated with higher unpleasantness ratings and the urge to check during the task. In addition, higher levels of anxiety and obsessive-compulsive features related to general negative affect, uncertainty, and perfectionism were associated with greater checking frequency. Lastly, stronger obsessional beliefs about perfectionism and the need for certainty predicted poorer task accuracy, slower reaction times, and higher engagement of the corrugator supercilii.
