Ha. Llewellynthomas et al., CANCER-PATIENTS DECISION-MAKING AND TRIAL-ENTRY PREFERENCES - THE EFFECTS OF FRAMING INFORMATION ABOUT SHORT-TERM TOXICITY AND LONG-TERM SURVIVAL, Medical decision making, 15(1), 1995, pp. 4-12
The study purpose was to determine whether the framing of treatment in
formation influenced patients' reported preferences for participating
in treatment decision making and for trial entry. Ninety cancer patien
ts read either neutrally-, positively-, or negatively-framed informati
on about a chemotherapeutic treatment, then indicated their preference
s for participating in the treatment decision, and whether they would
participate in a clinical trial incorporating this protocol. There was
no difference across information groups in preferences for participat
ing in treatment decision making or willingness to enter such a clinic
al trial. Preference for participation in treatment decision making wa
s significantly related to age (t = 2.54; p = 0.022), sex (x2 = 3.89;
p = 0.05), and education (t = 2.54; p = 0.018); trial entry preference
s were unrelated to these demographic variables. These results imply t
hat, in this clinical context, attitudes towards participation in trea
tment decision making may be associated with characteristics of the pa
tient, and attitudes towards trial entry may be dependent upon the cli
nical characteristics of a particular trial, but neither set of attitu
des is influenced by the framing of protocol information.
