Suicidal imagery refers to an image or mental representation related to suicidal behavior. This study aims to develop a self-report measure of suicidal imagery, named the Suicidal Imagery Questionnaire (SIQ). In study 1, 21 items were developed based on previous research to measure three sub-components of suicidal imagery: spontaneous suicidal imagery, intrusive suicidal imagery, and vividness or preoccupation with suicidal imagery. Factor analysis supported a two-factor structure that included spontaneous suicidal imagery and intrusive suicidal imagery. The vividness or preoccupation factor was excluded. In study 2, the two-factor structure of suicidal imagery was confirmed in a separate sample of community adults and 10 items were included in the instrument. The 10-item self-report questionnaire of suicidal imagery had good internal consistency and test-retest reliability (after a two-weeks interval). The questionnaire had also good convergent and discriminant validity, as well as criterion-related validity. Overall, the SIQ is a reliable and valid assessment tool for suicidal imagery.
