felt from the work setting. Also, STEM assesses stable and current emotions at the same time, i.e. people are asked to mark the extent to which they felt each emotion "during your most recent day of work" and separately "How you generally feel when you are working". Another unique characteristic of the STEM is that it does not employ a standard Likert Scale that uses the same words to describe the points of the scale. Instead, several points of the scale are labelled with more precise emotion words related to the emotion in question, e.g. the scale for joy uses "amiable" as midpoint, "cheerful" to mark 8/10 and "happy" as positive extreme. DES-IV Differential Emotions Scale (DES) is developed on the basis of Differential Emotions Theory, which contends that emotions are closely related to the formation of personality. The scale advances to DES-IV with the theoretical development. DES-IV includes 36 items using a 5-point frequency Likert scale (from rarely or never to very often). These items can be divided into 12 categories that measure 12 fundamental emotions, which include interest, enjoyment, surprise, sadness, anger, disgust, contempt, fear, guilt, shame, shyness, and hostility inward. The inclusion of three sets of instructions allows the measure of long-term traits, persistent mood states and transient emotional states. It is viewed as a relatively reliable and flexible measure. POMS2 Profile of Mood States (POMS2) contains 65 items that assess seven mood state dimensions, labeled as nervousness (tension-anxiety), unhappiness (depression-dejection), fury (anger-hostility), energy (vigor-activity), exhaustion (fatigue-inertia), inability to concentrate (confusion-bewilderment) and friendliness. Compared to its first edition, POMS2 updated some of the core adjectives and added more normative sample. The popularity of POMS2 has enabled its use in various populations in clinical studies. Measures of negative affect STAXI The State-Trait Anger Expression Inventory (STAXI) has been developed as a 44-item questionnaire to assess stable (trait) and current (state) intensity of the expression of anger. Its current version is the STAXI-2 which has also been adapted for the use with children and adolescents. The STAXI(-2) distinguishes between the three modes of anger expression: anger-out, anger-in and anger-control. Anger-out refers to a tendency to express anger through either verbal or physical behaviors. Anger-in or suppressed anger refers to the tendency to hold one's anger on the inside without any outlet. Anger-control refers to the tendency to engage in behaviors intended to reduce overt anger expression. ARS The Anger
