A B S T R AC T The aim of this study was to ascertain the nature of the interaction between the affective value of musical distraction, personality type and performance on the cognitive tasks of reading comprehension, free recall, mental arithmetic and verbal reasoning in children aged 11-12 years. It was hypothesized that the cognitive performance of extraverts would be significantly poorer when in the presence of background music that has a negatively affective value than when in the presence of background music that has a positively affective value. It was predicted that the converse of this would be true of introverts and neurotic personality types. Although few significant results were found in support of the central hypothesis, several results supported theoretical assumptions and showed clear trends that warrant further investigation.

Background Breast cancer–related lymphedema (BCRL) is a well-known side effect of cancer and its treatment with wide-ranging prevalence estimates. Objective This study describes associations between breast cancer–related lymphedema (BCRL) signs, symptoms, and diagnosis for women who were African American, white, or had a low income and survived breast cancer. Design This is a cross-sectional, observational study that used a computer-assisted telephone interview. Methods Women who had survived breast cancer were queried on the presence of 5 lymphedema signs and symptoms (edema in the breast, axilla, arm, and/or hand; tissue fibrosis; pitting; hemosiderin staining; heaviness) and whether they had a diagnosis of BCRL. Relationships between signs/symptoms and diagnosis for each group were evaluated with kappa and chi-square statistics. Results The study sample included 528 women who had survived breast cancer (266 white and 262 African American), with 514 reporting complete data on household income; 45% of the latter reported an annual household income of ≤$20,000. Women who were African American or had a low income were nearly twice as likely as women who were white to have any of 8 signs/symptoms of BCRL. Regardless of race and income, >50% of women with all BCRL signs and symptoms reported that they were not diagnosed with BCRL. Limitations The main limitations of our study are the lack of medical chart data and longitudinal design. Conclusions Women who were African American or had a low income and had survived breast cancer had a greater burden of BCRL signs and symptoms than women who were white. The lack of a strong association between BCRL signs, symptoms, and diagnosis suggests that BCRL may be underdiagnosed. These findings suggest that more rigorous screening and detection of BCRL—especially for women who are African American or have a low income—may be warranted. Cancer rehabilitation programs may be able to fill this gap.
