Structure of Temperament Questionnaire
These characteristics are the most consistent aspects of the behaviour of an individual across his or her lifespan and are relatively independent of the content of the situation.
Initially, all versions of the STQ were developed and validated on adult samples and were designed for the purposes of organizational, educational and clinical psychology.
The STQ is based on the Eastern-European tradition of experiments investigating the types and properties of nervous systems.
It started from extensive experiments on several species of mammals, and then continued with human adults and children within the Pavlovian Institute of Highest Nervous Activity (Pavlov, 1941, 1957).
Similar to the Rusalov's STQ-150, the STQ-77 differentiates between the traits regulating motor-physical, social-verbal and mental-probabilistic aspects of behaviour.
The support of the STQ-77 architecture was recently reinforced by the review in neurochemistry research resulted in development of a neurochemical model Functional Ensemble of Temperament (FET) that maps an interplay between main neurotransmitter systems and temperament traits [12][13][14][23][16][17][15] The Extended (STQ-150) version was adapted to five languages: English, Russian, Chinese, Polish and Urdu.
Similar to the Rusalov's STQ-150, the STQ-77 differentiates between the traits regulating motor-physical, social-verbal and mental-probabilistic aspects of behaviour [1][19][20][21][22] Beginning from 2017 the STQ-77 is offered for free for a non-commercial use (research and personal testing) in 24 languages: Bulgarian, Chinese-Simplified, Chinese-Traditional, Dari, Dutch, English, Estonian, Finnish, French, German, Hebrew, Hindu, Italian, Japanese, Korean, Norwegian, Persian, Polish, Portuguese, Russian, Serbian, Spanish, Swedish, and Urdu.
[1][68][71] There are versions for screening child temperament in English and Russian for the ages 0–3, 4-7, 8-11 and 12-16, freely available on the website of test developers.
A battery of behavioural testing in line with 12 components of the STQ-77/FET has been developed for adult and children age groups in English and Russian.
The extended STQ-150 was also adapted in 6 languages: English (using US,[9][8][10] Australian [64] and Canadian [1][7] samples), Chinese-Simplified,[1] Russian,[1][7][5][11] Polish,[1][7][49] Urdu [1][7] and German.
