Reuter and Montag’s rRST Questionnaire, rRST-Q

Test scores

Higher scores indicate greater sensitivity within each system.

• Revised Behavioral Inhibition System (rBIS) – reflects sensitivity to conflict, uncertainty, and potential negative outcomes. Higher scores indicate greater indecisiveness, caution, worry, and difficulty tolerating uncertainty, whereas lower scores indicate a more decisive and less conflict-sensitive style.

• Revised Behavioral Activation System (rBAS) – reflects sensitivity to reward and approach motivation. Higher scores indicate greater spontaneity, energy, reward seeking, and readiness to act on opportunities, whereas lower scores indicate a more restrained and less reward-driven approach.

• Fight-Flight-Freeze System (FFFS) – reflects sensitivity to threat and punishment, associated with fear and avoidance. Higher scores indicate stronger tendencies toward avoidance, escape, and freezing responses, along with lower inclination toward defensive confrontation, whereas lower scores indicate reduced fearfulness and greater willingness to face threat.
