Which definition describes security threat groups?

• A. The study of how space between people is used as part of communication
• B. Short phrases that are interjected by the listener to encourage the speaker to continue sharing
• C. Groups within correctional institutions that promote violence against inmates or staff
• D. The process of interpreting body movement and gestures as a form of non-verbal communication

Answer: (C)

Security threat groups are organized groups inside correctional facilities that promote violence against inmates or staff. This definition captures the safety risk these groups pose to everyone and to the orderly operation of the facility. Recognizing this helps staff focus on risk assessment, intelligence gathering, and targeted interventions to reduce violence, control contraband, and maintain security. The other descriptions describe different aspects of communication—how physical space is used in interaction, back-channel cues that encourage someone to talk, and interpreting body movement as nonverbal communication—which are not related to security threat groups.
