Use of the Hand Test in the classification of psychiatric inpatient adolescents

This study investigates the extent to which 2 Hand Test variables, the Pathology summary score (PATH) and the Acting Out Score (AOS), were able to differentiate among 3 groups of adolescents. Thirty psychiatric inpatient adolescents diagnosed with various Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) behavioral and emotional disorders were compared to 30 outpatient and 30 nonclinical adolescents matched on age, grade, and sex. An analysis of variance demonstrated the ability of both PATH and AOS to significantly differentiate among the 3 groups. Multiple regression equations utilized PATH and AOS as significant predictors of inpatient status (p < .0001) and general patient (inpatient and outpatient) status (p < .0001). Utilizing diagnostic efficiency statistics, overall correct classification was found to be highest for PATH > or = 3 and AOS > or = 2. These findings support the application of the Hand Test as a useful assessment tool for adolescents suspected of having psychiatric disorders and present evidence for the use of PATH and AOS for classification purposes in ways that are clinically meaningful.
