Which statement best summarizes the difference between the constructs emphasized by the Health Belief Model (HBM), Social Cognitive Theory (SCT), and the Transtheoretical Model (TTM)?

HBM emphasizes perceived threat and benefit constructs and cues to action; SCT emphasizes observational learning, outcome expectancies, and reciprocal environment–person interactions; TTM emphasizes stages of readiness and processes of change.

HBM emphasizes stages of change and relapse prevention; SCT emphasizes only biological determinants of behavior; TTM emphasizes immediate threat perceptions and single-timepoint risk messaging.

HBM emphasizes community-level policy change as the primary construct; SCT emphasizes only rewards and punishments without cognitive processes; TTM emphasizes social modeling as the main mechanism of change.

HBM emphasizes skill-building and role-play as the central construct; SCT emphasizes perceived severity and susceptibility; TTM emphasizes universal education without tailoring.
