Profile of mood states questionnaire
POMS-f, TMD, anger, confusion, anxiety, fatigue, mood disturbance, anger/hostility, depression
The POMS-f is composed of 65 words/adjectives and assessing seven emotional states. Participants responded to each word/adjective on a 5-point scale (“0 = not at all” to “4 = very strong”) with higher scores indicating a more negative mood. The Cranach’s alphas were 0.88 for the anxiety/tension, 0.91 for the depression/dejection, 0.84 for the anger/hostility, 0.76 for the confusion/aberration, 0.80 for the vigor/activity, 0.77 for the fatigue/inertia, and 0.81 for the friendship. The scores for all items, except interpersonal relationships, were taken into account to measure the total mood disturbance (TMD) following this calculation: TMD = (anxiety + depression + anger + fatigue + confusion) – vigor.
