Abstract
This article describes the validation of a simple and rapid (one-minute) self-re ort questionnaire designed to assess dysphoric mood. It consists ofsix h e a r analog self-assessment ( U S A ) scales derived from the Profile of Mood States (POMS). Tests for associations between the POMS-LASA scales and two established questionnaires, the Symptom Checklist-90 (revised) and the POMS, have shown a good relationship. This technique has been demonstrated to be sensitive to changes in mood following group therapy. The use of the instrument in clinical settings and research protocols is discussed.
