Breast Cancer Knowledge and Preventive Behaviors An Urban Emergency Department-based Survey

ACADEMIC EMERGENCY MEDICINE, Issue 12 2000
Kevin M. Takakuwa MA
Abstract. Objective: To assess general knowledge and preventive behaviors regarding breast cancer among women who present to an urban emergency department. Methods: During a six-month study period, a convenience sampling of women aged 21 years and older who were in treatment and waiting areas was surveyed. The anonymous written survey asked about demographic variables, knowledge, and preventive behaviors regarding breast cancer. Knowledge was assessed with questions about the recommended frequency of breast self-examination and the recommended age for first mammography. Performance was assessed by questions about breast self-exam and mammography. Subgroup analysis was done by age (above and below 40 years old), race, income (above and below the median), insurance type, history of breast lump, and family history (FH) of breast cancer. Results: Four hundred women completed surveys. Two hundred twelve (53%) correctly knew the answers to the two knowledge questions. Knowledge was greater in women with private insurance. Knowledge of the frequency of breast self-exam was significantly greater among whites and Native Americans than among African Americans, Asians, or Hispanics. Stated performance of preventive behaviors was 72% (288) for breast self-exam and for mammography. Preventive behaviors were significantly more likely to be performed by higher-income and privately-insured women. Breast self-exam was more likely to be done in older women, those with a history of a breast lump, and those with a FH of breast cancer. Conclusions: Women with lower income and without private insurance were less likely to be knowledgeable and practice preventive measures for detecting breast disease. [source]

Two modes of con,dence rating: An effect of episodic information of participant's own past responses in a repeated-question paradigm

JAPANESE PSYCHOLOGICAL RESEARCH, Issue 2 2003
Masahiko Saito
Abstract: General knowledge questions with two answer alternatives were employed in experimental session 1; in session 2, the same questions were presented together with participants' own session-1 responses. In order to examine whether or not the episodic information of participant's own responses would suppress standard con,dence-rating mode in session 2, rates of answer- and con,dence-changes between sessions were analyzed. In session 2, participants were able to change the con,dence value to another, if they thought the initial value inadequate. They then had a chance to change the answer to the other and rated their con,dence in the new answer. The major results were as follows: (a) Between-session answer change rate was very low; (b) Between-session answer change rate was not a monotonic decreasing function of con,dence; (c) However, the rate depended on con,dence change from session 1 to before-answer-change rating. These results clearly contrasted with a previous study (Saito, 1998) in which episodic information of participant's own session 1 answers and con,dence values was not presented. It was argued that the episodic information triggered another mode of con,dence rating or a decision inertia effect. [source]

A neuropsychological dimension for anchoring effects

JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 5 2005
John D. Jasper
Abstract Previous research has shown that strength of handedness predicts differences in sensory illusions, Stroop interference, episodic memory, and beliefs about body image and the origin of species. Recent evidence also suggests handedness differences in the susceptibility to information framing and persuasion. The present paper extends this line of work to decision anchoring effects. In Experiment 1, 131 introductory psychology students responded to 12 real-world knowledge questions after being given random, uninformative high or low anchors. Results indicated that "strong-handers" showed larger anchoring effects than "mixed-handers." In Experiment 2, 89 introductory psychology students responded to 6 real-world knowledge questions in a modified, two-step anchoring task in which participants were given a credible source for the anchored information and asked to give pre- and post-anchor estimates. In contrast to Experiment 1, results revealed that mixed- and strong-handers were affected similarly by anchoring. In Experiment 3, 158 students were asked to estimate the answer to one of two versions of 8! (8,×,7,×,6,×,5,×,4,×,3,×,2,×,1 or 1,×,2,×,3,×,4,×,5,×,6,×,7,×,8),a multiplication problem in which the high and low anchors are inherently informative. Here, mixed-handers showed larger anchoring effects than strong-handers. A theory centered around the notion of hemispheric specialization and the communication between the two halves of the brain as well as arguments about the informativeness of anchors, metacognition, and recent theorizing in the anchoring literature are used to account for these data.

Stereotype Threat and Race of Interviewer Effects in a Survey on Political Knowledge

AMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 1 2003
Darren W. Davis
Social desirability is generally thought to underlie the propensity for survey respondents to tailor their answers to what they think would satisfy or please the interviewer. While this may in fact be the underlying motivation, especially on attitudinal and opinion questions, social desirability does not seem to be an adequate explanation for interviewer effects on factual questions. Borrowing from the social psychology literature on stereotype threat, we test an alternative account of the race-of-interviewer effects. Stereotype threat maintains that the pressure to disconfirm and to avoid being judged by negative and potentially degrading stereotypes interferes with the processing of information. We argue that the survey context contains many parallels to a testing environment in which stereotype threat might alter responses to factual questions. Through a series of framing experiments in a public opinion survey and the reliance on the sensitivity to the race of the interviewer, our results are consistent with expectations based on a theory of "stereotype threat." African American respondents to a battery of questions about political knowledge get fewer answers right when interviewed by a white interviewer than when interviewed by an African American interviewer. The observed differences in performance on the political knowledge questions cannot be accounted for by differences in the educational background or gender of the respondents. [source]

Correlates of breast reconstruction,

CANCER, Issue 11 2005
Results from a population-based study
Abstract BACKGROUND Immediate or early postmastectomy breast reconstruction is performed infrequently. To the authors' knowledge, little is known regarding surgeon or patient perspectives on reconstruction treatment decisions. The purpose of the current study was to identify patient attitudes and preferences associated with breast reconstruction, and whether these differed by race. METHODS A sample of women age , 79 years who were diagnosed with ductal carcinoma in situ and invasive breast carcinoma between December 2001 and January 2003 was identified from the Surveillance, Epidemiology, and End Results (SEER) registries of Detroit and Los Angeles. Eligible subjects completed a questionnaire at a mean of 7 months after diagnosis. The Wald chi-square test and logistic regression were used for data analysis. RESULTS Of the 1844 respondents, 646 underwent a mastectomy (35.0% of the total sample) and 245 of these patients received breast reconstruction (38.0%; of the mastectomy group). On multivariate analysis, younger patient age, higher educational levels, and earlier stage of disease were found to be significantly associated with breast reconstruction. Although 78.2% of women reported that breast reconstruction was discussed, only 11.2% correctly answered 3 basic knowledge questions regarding the procedure. The desire to avoid more surgery was the most common reason for not undergoing breast reconstruction. CONCLUSIONS The results of the current study found that the majority of women were aware of breast reconstruction but choose not to undergo the procedure. Lack of knowledge and a greater perception of barriers to the procedure were more common among African-American patients and women with a lower education level, suggesting a need for improved educational strategies.
