The development of the Negative Mental Imagery Questionnaire (MIQ-N).

Background: Mental imagery plays a key role in the onset and maintenance of psychological disorders, and has become the target of psychological interventions for the treatment of several anxiety-related conditions. However, there are currently no transdiagnostic measures designed to assess the varied dimensions of mental imagery relevant to psychopathology.

Aim: To develop and validate a new measure assessing the experiences and appraisals of negative mental imagery.
