The Structure of Temperament Questionnaire (STQ) proposed by Rusalov (1989) measures four dynamical properties of activity -Ergonicity (energetic aspect), Plasticity, Tempo of Activity, and Emotionality-in three different areas: physical, social, and intellectual. The paper presents an investigation of the relationships between temperament scales in English, Chinese, Urdu and Polish versions of the STQ. The multi-group confirmatory factor analysis showed a better fit for activity-specific models of temperament than the General Arousal model and suggested a four-factor structure of temperament in each STQ version: factors of Motor Activity (Motor Ergonicity, Motor Plasticity and Motor Tempo scales), Social Activity (Social Ergonicity, Social Plasticity and Social Tempo scales), Intellectual Activity (Intellectual Ergonicity, Intellectual Plasticity and Intellectual Tempo scales) and Emotionality (Motor, Social and Intellectual Emotionality scales). © International Journal of Psychology & Psychological therapy.
