This discussion of an online, in-house computer system used in a group clinical psychology practice describes the development of a program designed to offer cost-effective testing services for patients of mental health professionals. The report provides detailed information on two psychological testing inventories rendered via computer. The first is a Sexual Adjustment Inventory, which enables therapists to survey an individual's sexual adjustment; the second is a Self Discovery Program which utilizes the computer to administer pre- and post-session tests to document behavioral and emotional changes exhibited by course participants. An outline of other available tests is provided, including a Stress Anxiety Scan, an Assertive Scale, a Fear Inventory, a Dissimilation Index, an Index of Somatic Problems, a Beck Depression and Hopelessness Scan, a Social History Scan, a Symptom Checklist, a Minnesota Multiphasic Personality Inventory, an Intellectual Screening Battery, and a Career Assessment Survey. Tests projected for future marketing are a Personality Inventory for Children, a Rorschach Interpretation, and a Visual Searching Task for diagnosing neurologically impaired patients. (MER)
