Lung cancer patients' decisions about clinical trials and the theory of planned behavior.

The theory of planned behavior explores the relationship between behavior, beliefs, attitudes, and intentions presupposing that behavioral intention is influenced by a person's attitude about the behavior and beliefs about whether individuals, who are important to them, approve or disapprove of the behavior (subjective norm). An added dimension to the theory is the idea of perceived behavioral control, or the belief that one has control over performing the behavior. The theory of planned behavior suggests that people may make greater efforts to perform a behavior if they feel they have a high level of control over it.

The guinea pig syndrome: improving clinical trial participation among thoracic patients.

Background: The purpose of the study was to examine lung cancer patients' knowledge, attitudes, and behavior regarding clinical trials and to develop an effective intervention for increasing patient knowledge and awareness of clinical trials for lung cancer patients.

Methods: Qualitative semistructured, in-depth interviews were conducted with (1) new patients who had not yet interacted with their physicians, (2) existing patients who had participated in a clinical trial, and (3) existing patients who had not been offered a trial. Findings from the interviews led to the creation of a letter that was sent to all new patients before their first appointment, explaining that offering a clinical trial at this hospital was the norm, to expect this discussion, and the option of standard treatment was always available.
