תקציר	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.	The Transformational Leadership Scale (TLS), operationalized in the Multifactor Leadership Questionnaire (MLQ), was developed by Bass and Avolio (1985, 1991) to measure leadership styles across a continuum from transactional to transformational. Transformational leadership comprises four dimensions: idealized influence (role modeling and inspiration), inspirational motivation (articulating compelling vision), intellectual stimulation (encouraging innovation), and individualized consideration (personalized development). The scale has become foundational in organizational psychology and management research for understanding leadership effectiveness and organizational outcomes.
