Consists of 65 items or symptoms; patients indicate on a five-point agree-ment scale (not at all to extremely) the extent to which they experienced each symptom during the preceding seven days. The POMS has six subscales:tension-anxiety, depression-dejection, anger-hos-tility, vigor-activity, fatigue-inertia, and confusing-bewilderment.
A total mood disturbance score sums the scores of the six factors (weighting vigor negatively) and was used in this study.
Internal consistencies of the six subscales in normative samples were all near 90 or above.
