A person’s expressed likelihood of engaging in behaviors that involve prevention or treatment of a health condition is measured with four, seven-point questions.  The particular health condition is not stated in the questions and should be provided in the instructions or the context of the study.

The scale is composed of four, seven-point items intended to measure person's interest in and likelihood of trying a particular prescription medication.

The degree to which a patient provided information and was actively involved in decision making with his/her physician during a specific visit is measured with four, seven-point Likert-type items.

The degree to which a patient is pleased with the service provided by a physician and the medical facility during a specific visit is measured with three, seven-point Likert-type items.

The purpose of the scale is to evaluate the importance of a group of information sources in learning about a health-related topic.

Three, five-point, Likert-type statements are used to measure the extent to which a physician believes that pharmaceutical advertising has had a positive impact on the prescriptions he or she has subsequently written.
