The Adult Inventories include the behavioural symptoms of more than two dozen DSM-IV ™ psychiatric disorders. The Adult Self-Report Inventory-4 (ASRI-4) is completed by the patient (135 items), and the Adult Inventory -4 (AI-4) is filled out by someone who knows the patient well. When clinicians obtain ratings prior to the patient interview, they can review the answers and ask more detailed questions about specific problem areas, which can save time as well as highlight easily overlooked comorbid conditions. The Adult Self-Report Inventory can be scored according to symptom count criteria (diagnostic model) or symptom severity model (normative data model). ASRI-4 scores demonstrate satisfactory internal consistency and test-retest reliability, correlate with specialized measures of ADHD, anxiety, depression, bipolar disorder, social phobia, PTSD, eating disorders, and substance use, and differentiate patients with versus without specific diagnoses and between clinical and non-clinical samples.
