  The GTIPS is a valid and reliable 11-item measure of general trust in physicians in the domains of dependability, confidence, and confidentiality of information. All items are fashioned in a 5-point Likert format with a minimum score of 11 and maximum of 55. Higher scores indicate more trust in physicians.

All questions are measured on a Likert scale, with scores ranging from a minimum of 10 to a maximum of 50. Higher scores indicate more distrust in the health care system.
