สรุป	The Organizational Commitment Scale (OCS), developed by Meyer and Allen in 1991, measures three distinct dimensions of organizational commitment: affective commitment (emotional attachment), continuance commitment (perceived cost of leaving), and normative commitment (sense of obligation). This three-component model has become foundational in understanding employee retention, engagement, and organizational attachment.	The Psychological Safety Scale (PSS), developed by Amy Edmondson in 1999, measures team members' shared perception that they can take interpersonal risks—speaking up, asking questions, admitting mistakes, proposing new ideas—without fear of embarrassment, punishment, or rejection. The 7-item scale captures a team-level construct fundamental to learning, innovation, and psychological well-being. High psychological safety predicts team performance, learning from errors, information sharing, and adaptive responses to change.
