The effect of telephone versus print tailoring for mammography adherence.

OBJECTIVE: The purpose of this intervention was to increase mammography adherence in women who had not had a mammogram in the last 15 months. METHODS: A prospective randomized intervention trial used four groups: (1) usual care, (2) tailored telephone counseling, (3) tailored print, (4) tailored telephone counseling and print. Participants included a total of 1244 women from two sites-a general medicine clinic setting serving predominately low-income clientele and a Health Maintenance Organization (HMO). Computer-tailored interventions addressed each woman's perceived risk of breast cancer, benefits and/or barriers and self-efficacy related to mammography screening comparing delivery by telephone and mail. RESULTS: Compared to usual care all intervention groups increased mammography adherence significantly (odds ratio 1.60-1.91) when the entire sample was included. CONCLUSIONS: All interventions groups demonstrated efficacy in increasing mammography adherence as compared to a usual care group. When the intervention analysis considered baseline stage, pre contemplators (women who did not intend to get a mammogram) did not significantly increase in mammography adherence as compared to usual care. PRACTICE IMPLICATIONS: Women who are in pre contemplation stage may need a more intensive intervention.

Tailored interventions for screening mammography among a sample of initially non-adherent women: when is a booster dose important?

OBJECTIVE: To assess added value of a booster dose of a tailored mammography intervention. METHODS: Participants, non-adherent at baseline, were randomly assigned to usual care or one of three tailored interventions. Intervention group members (n=657) were further randomly assigned to receive/not receive a booster intervention dose. Electronic record mammography data were collected following initial intervention and at 6 and 15 months post-booster. RESULTS: Booster had no effect among women not screened after first intervention dose (n=337). Among women screened after initial dose (n=320), booster predicted re-screening at 6 but not 15 months. A boosterxrace interaction showed a booster effect at 6 months for African Americans (OR=4.66, p=.0005) but not Caucasians (OR=0.74, p=.44). CONCLUSIONS: Findings suggest if a first-dose intervention does not facilitate screening, neither will a booster dose. However, among women for whom a first dose is effective, boosters can facilitate timely repeat adherence, especially among African Americans. At 6 months booster recipients were less likely to be off-schedule but, by 15 months, the groups were similar. PRACTICE IMPLICATIONS: Boosters may effect when, but not whether, women continue screening.

Studying communication in oncologist-patient encounters: the SCOPE Trial.

STUDY OBJECTIVE: Most oncologists have not received adequate training in physician-patient communication, and existing effective courses tend to be time and resource intensive. We are developing and testing a tailored CD-ROM educational intervention that includes feedback on oncologists' own audio-recorded conversations with their advanced cancer patients. In this report, we describe the study methods and identify challenges to implementation and how these were overcome. STUDY DESIGN: A three-phase, randomized, controlled trial. In Phase 1, we audio-recorded oncologist-patient clinic encounters. In Phase 2, oncologists were randomly assigned to a communication CD-ROM intervention or control. Phase 3 consisted of audio-recording all participating oncologists conversing with a new sample of patients, two to 12 months after the intervention, to assess its effectiveness. SETTING: Oncology clinics at Duke University Medical Center (DUMC) and the Durham Veterans Affairs Medical Center (DVAMC) in Durham, NC, and the University of Pittsburgh Medical Center (UPMC) in Pittsburgh, PA. PARTICIPANTS: Medical, radiation and gynecological oncologists and their patients with advanced cancer. INTERVENTION: A tailored CD-ROM that contains an interactive educational interface with reference materials and video-clips of model conversations, along with the oncologists' own Phase 1 audio-recorded conversations. CONCLUSION: We present challenges and solutions to oncologist recruitment, identifying appropriate patients with advanced cancer, adapting to clinic flow, and developing a self-administered communications intervention.

Development of a self-efficacy scale for mammography.

Mammography screening has been demonstrated to decrease mortality from breast cancer. Although adherence rates have increased, there is still a need to increase annual screening. Self-efficacy is a construct that has been found useful in predicting behaviors. Measurement of self-efficacy needs to be specific to the behavior and to have good validity and reliability. The purpose of this study is to describe development of a self-efficacy instrument to measure confidence in obtaining a mammogram. Bandura's model guided item development. Construct validity was measured using confirmatory factor analysis and logistic regression. Cronbach alpha was used to test internal consistency reliability. A Cronbach alpha coefficient of .87 was obtained. The mammography self-efficacy scale evidenced content and construct validity.

Initiation and discontinuation of hormone therapy for menopausal symptoms: results from a community sample.

Factors related to initiation and discontinuation of hormonal therapy (HT) for treatment of menopausal symptoms were examined in a community sample of 533 peri/postmenopausal women aged 45-54 by telephone three times. Over 40 variables including: sociodemographic characteristics, clinical reasons to start HT use, HT contraindications, HT attitudes/knowledge, and health behaviors were examined in logistic regression models comparing women who discontinued HT to women who continued using HT over 9 months (discontinuers) and women who initiated HT versus women who never used HT over 9 months (initiators). Increased understanding of HT, confidence, mental health symptoms, perception that menopause is natural, and having gynecological surgery were related to decreased likelihood of HT discontinuation. Increased understanding about risks of HT, vasomotor symptoms, mood symptoms, and having gynecological surgery were related to increased likelihood of HT Initiation. These findings highlight the importance of physicians discussing HT with their patients, particularly because of recent clinical trial developments.

Informing cancer prevention strategies for African Americans: the relationship of African American acculturation to fruit, vegetable, and fat intake.

Acculturation has been associated with health-related behaviors in African Americans. We sought to determine if there is a relationship between acculturation and dietary intake in African Americans. African Americans in the PREMIER trial completed the African American Acculturation Scale (AAAS) and 2 nonconsecutive 24-h dietary recalls (n = 238). Analysis of variance (ANOVA) and canonical correlation were used to assess relationships between acculturation and dietary intakes. Canonical correlation (p = 0.05) showed that traditional African Americans had lower intakes of fruits/vegetables and milk/dairy with higher intakes of fats, meat, and nuts. This pattern was supported by differences in the ANOVA. African American acculturation is related to dietary intake. These findings have implications for the design of cancer-related public health messages targeted to African Americans.

Patients' interest in discussing cancer risk and risk management with primary care physicians.

Little is known about patients' preferences for discussing cancer risks and risk management with primary care physicians. We sought to determine whether patients want to discuss such topics and what factors are associated with this interest. Participants (375 patients ages 40-85, of diverse race and education level) completed a telephone survey prior to scheduled physician visits. Survey included items on perceived health, perceived cancer risk, education level, and whether participants would like to discuss with a physician their breast, ovarian or colon cancer risk, tamoxifen, cancer genetic counseling, and colon cancer screening. Greater proportions were interested in discussing risks for each cancer, compared with those who were not (P < 0.0001). More participants were interested in discussing mammograms (80%) and cancer genetic counseling (60%) than tamoxifen (49%) or colon cancer screening modalities (43-53%). For many topics, poorer perceived health was associated with greater interest in future discussion; higher education level was associated with less interest.

Increasing colorectal cancer screening among individuals in the carpentry trade: test of risk communication interventions.

BACKGROUND: Individuals in the carpentry trade, due to lifestyle habits and occupational exposures, may be at above-average risk for colorectal cancer (CRC). Based on the literature which suggests that increasing perceived risk motivates behavior change, we report on the effectiveness of four risk-communication interventions targeted to increase initial, yearly and repeat fecal occult screening (FOBT) among carpenters (N = 860) over a 3-year period. METHODS: Our 2 x 2 factorial design intervention study varied two dimensions of providing CRC risk factor information: (1) type of risk factor-one set of interventions emphasized three basic risk factors (age, family history and polyps); the other set emphasized a comprehensive set of risk factors including basic, lifestyle, and occupational factors, and (2) tailoring/not tailoring risk factor information. Participants were provided FOBTs. Outcomes were the proportion of returned FOBTs. RESULTS: Varying the amount and intensity of delivering CRC risk factors information affected neither risk perceptions nor initial, yearly, or repeat screening. However, yearly and repeat screening rates were greater among participants who received interventions addressing comprehensive set of risk factors, especially with increasing age. CONCLUSIONS: Tailoring on several CRC risk factors appears insufficient to increase and sustain elevated perceptions of CRC risks to promote screening.

Pain predicts non-adherence to pap smear screening among middle-aged African American women.

BACKGROUND: Middle-aged African American women have the highest incidence and mortality of invasive cervical cancer in the United States and the lowest adherence to pap smear screening. METHODS: In 2001, we identified factors associated with non-adherence to screening recommendations using three focus group interviews and subsequently developed a questionnaire administered to 144 African American women aged 45 to 65 years. RESULTS: The perception that the Pap test was painful was associated with non-adherence to screening recommendations (OR = 4.78; 95%CI: 1.67-13.7). Difficulty to pay for the office visit coupled with perceived pain was associated with a nearly sixfold increase in risk of non-adherence (OR = 5.8; 95%CI: 2.8-15.5). Previously identified barriers to screening including lower education and socioeconomic status, poor access to care, knowledge of and exposure to known risk factors of invasive cervical cancer, cancer fatalism, and perceived racism were not independently associated with non-adherence. CONCLUSIONS: These data suggest that, among middle-aged African American women, future interventions addressing pain during a Pap test will likely increase acceptability of and adherence to cervical cancer screening. Pain could be addressed either by providing information during the pap test and/or using smaller lubricated speculums.

Impact of the Cancer Risk Intake System on patient-clinician discussions of tamoxifen, genetic counseling, and colonoscopy.

The Cancer Risk Intake System (CRIS), a computerized program that "matches" objective cancer risks to appropriate risk management recommendations, was designed to facilitate patient-clinician discussion. We evaluated CRIS in primary care settings via a single-group, self-report, pretest-posttest design. Participants completed baseline telephone surveys, used CRIS during clinic visits, and completed follow-up surveys 1 to 2 months postvisit. Compared with proportions reporting having had discussions at baseline, significantly greater proportions of participants reported having discussed tamoxifen, genetic counseling, and colonoscopy, as appropriate, after using CRIS. Most (79%) reported CRIS had "caused" their discussion. CRIS is an easily used, disseminable program that showed promising results in primary care settings.

A cost-effectiveness comparison of three tailored interventions to increase mammography screening.

BACKGROUND: Mammography is the primary method used for breast cancer screening. However, adherence to recommended screening practices is still below acceptable levels. This study examined the cost-effectiveness of three combinations of tailored telephone and mailed intervention strategies for increasing adherence to mammography. METHODS: There were 1044 participants who were randomly assigned to one of four groups. A logistic regression model with adherence as the dependent variable and group as the independent variable was used to test for significant differences, and a ratio of cost/improvement in mammogram adherence evaluated the cost-effectiveness. RESULTS: All three of the interventions (tailored telephone, tailored mail, and tailored telephone and mail) had significantly better adherence rates compared with the control group (usual care). However, when also considering costs, one emerged as the superior strategy. The cost-effectiveness ratios for the three interventions show that the tailored mail (letter) was the most cost-effective strategy, achieving 43.3% mammography adherence at a marginal cost of dollar 0.39 per 1% increase in women screened. The tailored mail plus telephone achieved greater adherence (49.4%), but at a higher cost (dollar 0.56 per 1% increase in women screened). CONCLUSIONS: A tailored mail reminder is an effective and economical intervention to increase mammography adherence. Future research should confirm this finding and address its applicability to practice in other settings.

A breast cancer fear scale: psychometric development.

Fear of breast cancer has been inversely associated with participation in screening. However, investigators have generally used only one item or global scales to measure fear. This report describes development of a fear scale specific to breast cancer. Data from a large study involving mammography adherence were used to test the breast cancer fear scale for validity and reliability. Construct validity was verified through factor analysis and regression analysis predicting mammography. All items loaded on a single factor and theoretical relationships were verified by linear and logistic regression. The Cronbach alpha for the scale was.91.

Modifying attributions of colorectal cancer risk.

We report how a four-group risk communication intervention targeted to individuals in the carpentry trade affected their perceived causes (i.e., attributions) for increased colorectal cancer (CRC) risk. The intervention varied the amount of information presented on CRC risk factors and whether participants received tailored feedback on their risk factors. In baseline and 3-month follow-up telephone surveys, carpenters (N = 860) reported their perceived absolute and comparative CRC risks, perceived causes for increased CRC risk, and knowledge of CRC risk factors. At follow-up, neither the type or amount of information provided, nor the use of tailoring, appreciably and consistently affected whether participants mentioned their specific risk factor (e.g., lifestyle, occupational) emphasized in their intervention information. Furthermore, attributions did not affect CRC risk perceptions. These results suggest that participants do not integrate sufficiently CRC risk factor information into their conceptualizations of CRC risk, and that more effective methods are needed to contextualize risk factors information to achieve the goal of modifying CRC risk perceptions.

Minority recruitment in hereditary breast cancer research.

Although recruitment of ethnic and racial minorities in medical research has been evaluated in several studies, much less is known about the methods used to recruit these populations to participate in cancer genetics research. This report reviews the resources that have been used to identify and recruit ethnic and racial minorities to participate in hereditary breast cancer research. Overall, hospital-based resources were used most often to identify potential subjects, and active recruitment methods were used most frequently to enroll eligible subjects. This review suggests that there appears to be a finite number of resources and strategies to identify and recruit potential subjects to participate in cancer genetics research; however, options for improving awareness about cancer genetics research among ethnic and racial minorities have not been extensively evaluated. To study ethnic and racial minority participation in cancer genetics research, stronger evaluation components will need to be integrated into research methods. Both observational and experimental studies are needed to determine resources that are most effective for identifying potential subjects who are ethnic and racial minorities and to evaluate the effects of different recruitment strategies on enrollment decisions among these populations.

Racial differences in enrolment in a cancer genetics registry.

BACKGROUND: Lower enrolment of minorities into research studies has been reported frequently. Most studies have little information about nonparticipants, making it difficult to identify characteristics associated with enrolment and how they might vary by race. METHODS: Women who had previously participated in a population-based, case-control study of breast cancer in North Carolina were invited to enroll in a cancer genetics registry. Detailed questionnaire data on sociodemographic characteristics and cancer risk factors were available for all women. We compared characteristics of women who agreed to be in the registry with those who were deceased, were unlocatable, or declined enrolment. Unconditional logistic regression analyses were done to identify predictors of enrolment. RESULTS: Enrolment rates were markedly lower among African Americans than Whites (15% and 36%, respectively) due to both lower contact rates (41% versus 63%) and lower enrolment rates among those contacted (37% versus 58%). Logistic regression models suggested that racial differences in enrolment were not due to socioeconomic characteristics or other cancer risk factors; race was the only significant predictor of enrolment in multivariable models (odds ratio 0.41, 95% confidence interval 0.23-0.72). CONCLUSIONS: Although all women had previously taken part in a research study, African American women were less likely to enroll in the cancer genetics registry than White women. A possible explanation of these findings is that studies of genetics may present particular concerns for African Americans. Further research is needed to identify attitudes and issues that present barriers to participation among minorities.

Comparison of tailored interventions to increase mammography screening in nonadherent older women.

BACKGROUND: Recent increases in mammography use have led to a decrease in mortality from breast cancer. METHODS: Building on the Health Belief Model, the Transtheoretical Model, and past effectiveness of tailored interventions, we conducted a prospective randomized trial (n = 773) to test the efficacy on mammography adherence of tailored interventions delivered by five different methods, i.e., telephone counseling, in-person counseling, physician letter, and combinations of telephone with letter and in-person with letter. RESULTS: All five interventions increased mammography adherence significantly relative to usual care (odds ratios, 1.93 to 3.55) at 6 months post intervention. The combination of in-person with physician letter was significantly more effective than telephone alone or letter alone. Women thinking about getting a mammogram at baseline were more likely to be adherent by 6 months; even those in usual care achieved 48% adherence compared with 50-70% in the intervention groups. In contrast, women not thinking about getting a mammogram needed the interventions to increase their adherence from 13% to over 30%. CONCLUSIONS: All five interventions were effective at increasing mammography adherence. Women not thinking about getting a mammogram were most likely to benefit from these tailored interventions while other women might need less intensive interventions.

Accuracy of self-reports of fecal occult blood tests and test results among individuals in the carpentry trade.

BACKGROUND: Inaccuracy in self-reports of colorectal cancer (CRC) screening procedures (e.g., over- or underreporting) may interfere with individuals adhering to appropriate screening intervals, and can blur the true effects of physician recommendations to screen and the effects of interventions designed to promote screening. We assessed accuracy of self-report of having a fecal occult blood test (FOBT) within a 1-year window based on receipt of FOBT kits among individuals aged 50 and older in the carpentry trade (N = 658) who were off-schedule for having had a FOBT. METHOD: Indices of evaluating accuracy of self-reports (concordance, specificity, false-positive and false-negative rates) were calculated relative to receipt of a mailed FOBT. Among those who mailed a completed FOBT, we assessed accuracy of reporting the test result. RESULTS: Participants underestimated having performed a FOBT (false-negative rate of 44%). Accuracy was unrelated to perceptions of getting or worrying about CRC or family history. Self-reports of having a negative FOBT result more consistently matched the laboratory result (specificity 98%) than having a positive test result (sensitivity 63%). CONCLUSIONS: Contrary to other findings, participants under- rather than over reported FOBT screening. Results suggest greater efforts are needed to enhance accurate recall of FOBT screening.
