Reliability and Validity of the Suicide Intervention Response Inventory

To assess the reliability & validity of the Suicide Intervention Response Inventory, 177 practice teachers & 26 crisis-intervention volunteers completed it before & after a suicide-intervention training package. Internal reliability was strong & validity was modest. Practice teachers who received training improved as expected, & experienced volunteers scored higher than inexperienced volunteers. Improvement of the format of the items is recommended to enhance the validity of the Inventory.
