Sammanfattning	Team psychological safety is the shared belief among members of a team that the team is safe for interpersonal risk-taking — that one can speak up, ask questions, admit mistakes, and propose ideas without fear of being embarrassed, rejected, or punished. Amy Edmondson introduced and measured the construct in her 1999 Administrative Science Quarterly study of work teams in a manufacturing company, showing that it is a property of the team, not just the individual, and that it enables team learning behavior. Her measurement approach treats psychological safety as a latent belief captured by self-report items, aggregated to the team level once within-team agreement justifies it. The pivotal finding was that psychological safety predicts learning behavior, which in turn mediates the relationship between safety and team performance. The construct has since become central to research and practice on teams, learning, and high-reliability work.	The Multifactor Leadership Questionnaire (MLQ) is the standard instrument for measuring the full-range leadership model, which spans laissez-faire (non-) leadership, transactional leadership, and transformational leadership. Building on James MacGregor Burns's distinction, Bernard Bass's 1985 book reframed transformational leadership as leaders who raise followers' aspirations and move them to perform beyond expectations, and operationalized it through the MLQ. The transformational factors are idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration; the transactional factors are contingent reward and management-by-exception; and laissez-faire represents the absence of leadership. The current MLQ-5X measures these as distinct factors rated by followers and self. Judge and Piccolo's 2004 meta-analysis established the criterion validity of the model, showing strong overall validity for transformational leadership and a substantial positive role for contingent reward.
