Factors influencing chemotherapy knowledge in women with breast cancer.

The study included 46 women, and the sample was well educated and high income, so results may not apply to patients with lower literacy or different backgrounds. It was a cross-sectional survey after routine teaching, so it can show associations but cannot show that health literacy, income, or marital status caused better chemotherapy knowledge. The chemotherapy knowledge questionnaire was revised for plain language but was not tested for validity. The functional health literacy test was read aloud or along with participants, which may bias results because it was designed to be read without assistance. The word recognition test may misjudge patients whose first language is not English or whose cultural background affects pronunciation. Cognitive impairment was excluded by clinical judgment, not a formal assessment. Because participants had already received the center's mandatory one-hour chemotherapy session, a teaching booklet, and optional resources, this paper cannot separate the contribution of any one teaching component.

The supplied text does not include a conflicts of interest or funding statement. The provided publication types list research support from NIH, extramural, and non-U.S. government sources.

Do not read these associations as proof that low literacy causes poor chemotherapy knowledge or that a brief literacy check will improve outcomes. The study was small, cross-sectional, and did not test an intervention.
