The reinforcement sensitivity theory affects questionnaire (RST-AQ). A validation study of a new scale targeting affects related to anxiety, approach motivation and fear

Abstract

This paper presents the RST-AQ, a 22-item scale to measure the affective states related to the three motivational systems postulated by Reinforcement Sensitivity theory (RST-AQ): the Behavioral approach system (BAS), Behavioral inhibition system (BIS), and the Fight-Flight-Freeze system (FFFS). The three subscales are internally consistent. Results show an overall support for construct validity of our RST-AQ measure. The correlations of the RST-AQ subscales with other measures demonstrate a good convergent and divergent validity with regard to the subscales of BAS and BIS. The RTS-AQ Scale provides researcher with the first instrument to measures the affective states of the RST theory.
