The Developmental Inventory of Sources of Stress (DISS) is an instructional tool designed to assist counselors, advisors, and faculty in reducing stress among college students (specifically, high risk college freshmen, although it can be utilized effectively with any college student population). The instrument focuses on sources of stress over which students can exert control, as opposed to life experiences (e.g., death of a parent) over which they have no control. The DISS consists of five scales: (1) Time Management; (2) Physical Stressors; (3) Chemical Stressors; (4) Academic; and (5) Interaction. Results of a test-retest study of the test's reliability among freshmen at a large public southeastern university and group means for freshmen at the University of Georgia are presented. There was considerable interaction among variables serving as sources of stress. Efficient time management may have a large impact on life-style and academic performance. A copy of the DISS is attached. (SLD)
