Reasons for Quitting

The RFQ is composed of 20 self-report items, and measures intrinsic and extrinsic motivation for quitting smoking. It consists of two intrinsic motivation subscales, self-control (e.g., "To show myself I can quit if I really want to") and health concerns (e.g., "Because I'm concerned that smoking will shorten my life"), and two extrinsic motivation subscales, immediate reinforcement (e.g., "To save money that I spend on cigarettes") and social pressure (e.g., "Because someone has given me an ultimatum to quit"). The RFQ is both valid and reliable and may be useful from a research perspective as well as a clinical one, especially in randomized trials when comparing one study population to another.
