The Leader Member Exchange is a seven-item widely used self-administered instrument designed to measure the quality of the working relationship between supervisors and employees. It is very concise and measures three dimensions of leader-member working relationships: respect, trust, and obligation. The questionnaire includes items such as, "Do you know where you stand with your leader?" "How well does your leader understand your job problems and needs?" and " How would you characterize your working relationship with your leader?" Each item is measured on a Likert-type scale of a sum of five-points per item (left to right), indicating the degree to which the employee thinks the item is true. In the field of substance abuse, the LMX-7 has been used to examine relationships between supervisiors and clinicians in community treatment programs.
