“…FPI-R is a personality questionnaire with 138 forced choice (yes/no) items, which has been frequently used in German-speaking countries (Clayton et al, 1994;Hehl & Ruch, 1985;Merikangas et al, 1993;Thomas & Kirkcaldy, 1988). FPI-R measures the following 12 personality traits: life satisfaction (e.g., overall satisfaction, good mood, positive attitude), social orientation (e.g., altruistic, ready to help, emphatic), achievement orientation (e.g., achievement motivated, ambitious, competitive), inhibition (e.g., socially unsure, afraid of contact), excitability (e.g., sensitive, not controlled), aggressiveness (e.g., spontaneously aggressive, stubborn), stress (e.g., strained, overloaded, burned out), somatic complaints (e.g., health complaints), health concerns (e.g., looking after self, health conscious), frankness (e.g., self-criticism, nonconformity, unorthodox), extraversion (e.g., sociable, impulsive), and emotionality (e.g., emotionally unstable, fearful).…”
