Telephone surveys in public health research.

Alfred C. Marcus; Lori A. Crane

The last 10 years have seen increasing use of telephone surveys in public health research. This paper reviews issues of sampling, data quality, questionnaire development, sćheduling of interviewers, respondent burden, interviewer effects, and the use of the computer in telephone interviewing. Throughout, the authors focus on findings from recent research, with particular emphasis on those studies suggesting new advances or protocols for conducting telephone health surveys. The findings of this review suggest four conclusions. First, telephone interviews can be highly recommended for follow-up interviews in panel surveys that use an initial face-to-face interview. Second, telephone surveys can be recommended as a viable alternative to costly face-to-face surveys in cross-sectional studies of the general population. Third, when the focus of the survey is on subgroups of the population that have both low telephone coverage and higher rates of nonresponse (e.g., low income and low education respondents), telephone interviews should be used more cautiously. In these situations, a dual sampling frame approach (using a combination of face-to-face and telephone interviewing) may be considered. Finally, computer-assisted telephone interviewing (CATI) represents one of the most important and innovative technologic advances in health survey research in recent years. The advantages of CATI in improving survey management are noteworthy and ideally suited for moderate- to large-sample surveys. CATI also provides an attractive (and largely untapped) resource for testing and refining other methodologic protocols in survey research.

AbstractBACKGROUND: Colonoscopy has become a preferred colorectal cancer (CRC) screening modality. Little is known about why patients who are referred for colonoscopy do not complete the recommended procedures. Prior adherence studies have evaluated colonoscopy only in combination with flexible sigmoidoscopy, failed to differentiate between screening and diagnostic procedures, and have examined cancellations/no-shows, but not nonscheduling, as mechanisms of nonadherence. METHODS: Sociodemographic predictors of screening completion were assessed in a retrospective cohort of 647 patients referred for colonoscopy at a major university hospital. Then, using a qualitative study design, a convenience sample of patients who never completed screening after referral (n=52) was interviewed by telephone, and comparisons in reported reasons for nonadherence were made by gender. RESULTS: Half of all patients referred for colonoscopy failed to complete the procedure, overwhelmingly because of nonscheduling. In multivariable analysis, female sex, younger age, and insurance type predicted poorer adherence. Patient-reported barriers to screening completion included cognitive-emotional factors (e.g., lack of perceived risk for CRC, fear of pain, and concerns about modesty and the bowel preparation), logistic obstacles (e.g., cost, other health problems, and competing demands), and health system barriers (e.g., scheduling challenges, long waiting times). Women reported more concerns about modesty and other aspects of the procedure than men. Only 40% of patients were aware of alternative screening options. CONCLUSIONS: Adherence to screening colonoscopy referrals is suboptimal and may be improved by better communication with patients, counseling to help resolve logistic barriers, and improvements in colonoscopy referral and scheduling mechanisms.

In a large randomized trial involving over 2,000 women with abnormal cervical cytology (pap smear), three clinic-based interventions were tested as strategies to increase return rates for screening follow-up: 1) a personalized followup letter and pamphlet; 2) a slide-tape program on pap smears; and 3) transportation incentives (bus passes/parking permits). The three interventions were evaluated using a 2 × 2 × 2 factorial design. Results of this study confirm a high rate of loss to screening follow-up (i.e., no return visits) among women with abnormal pap smears (29% overall), with substantial variability among the 12 participating clinics (13% to 42/%). For the sample as a whole, both transportation incentives and the combined intervention condition of personalized follow-up and slide-tape program had a significant positive impact on screening follow-up. However, transportation incentives emerged as the dominant intervention condition among patient subgroups that can be characterized as more disadvantaged socioeconomically and at higher risk of developing cervical cancer, including patients receiving care from the county health department (odds ratio (OR) = 1.51; P<.05); patients without health insurance (OR = 1.77; P<.01); and patients with more severe pap smear results (OR = 1.71; P<.05). In contrast, among patient subgroups that can be characterized as relatively more advantaged and at lower risk of developing cervical cancer, only the combined intervention condition of personalized follow-up and slide-tape program was associated with a higher patient return rate. Subgroups reflecting this pattern included patients seen in noncounty clinics (OR = 4.54; P<.05) and patients with less severe pap smear results (OR = 5.16; P<.01). The implications of these findings are discussed in terms of designing clinic-based interventions to improve screening follow-up.

The Multidimensional Impact of Cancer Risk Assessment (MICRA) is a new tool to measure the specific impact of result disclosure after genetic testing. The authors compared its performance with that of questionnaires measuring general and cancer-specific distress. Participants (158 women) responded 1 month after they received genetic test results. The women were divided into 4 standard clinical test result groups: BRCA1/2 positive, BRCA1/2 negative, panel negative, and true negative. Factor analysis supported the formation of 3 subscales: Distress (6 items, alpha = .86), Uncertainty (9 items, alpha = .77), and Positive Experiences (4 items, alpha = .75). All 3 MICRA subscales differentiated participants who were BRCA1/2 positive from the other 3 groups. MICRA thus helps identify subgroups of vulnerable genetic testing participants.

Screening mammography rates and barriers to use: A Los Angeles county survey

Roshan Bastani; Alfred C. Marcus; Andrea Hollatz-Brown

The use of screening mammography among women 40 years of age and older in Los Angeles County was assessed through a random digit dial telephone interview. The sample of 802 women represents a large urban population with substantial proportions of blacks, Hispanics, and Asians. The survey obtained information regarding adherence to the ACS/NCI screening mammography guidelines, perceived benefits of early detection and mammography, perceived threat of developing breast cancer, and barriers to utilization. The results showed that 71% of the women had had at least one mammogram, with 49% having received a screening mammogram according to the guidelines for their age. Less than half the respondents knew the screening guidelines for their age, with women ages 40-49 years being less knowledgeable than women greater than or equal to 50 years old (29 vs 58% answering correctly). A logistic regression analysis predicting the likelihood of having obtained a screening mammogram according to the guidelines found the following to be predictive: concern over radiation (negative association), age (negative association), family history, knowledge of guidelines, and cost of a mammogram (negative association). Other demographic factors and beliefs were not significantly related to this dependent variable.

Smoking behavior among US Latinos: an emerging challenge for public health.

Alfred C. Marcus; Lori A. Crane

In this paper we review evidence on smoking and lung cancer among Latinos, including findings from several unpublished studies and technical reports. Recent surveys of smoking behavior in California, Texas, and New Mexico indicate a notable sex difference in smoking among Latinos, with Latino males smoking at least as frequently as White males, while Latino females report smoking rates considerably lower than White females. Our analysis of the 1979 and 1980 National Health Interview Surveys corroborates this finding and also indicates that this pattern holds true for subgroups of the Latino population, including country of origin. Taken together, these findings suggest that among Latino males rates of lung cancer and other cigarette-linked diseases may increase in the near future.

ABSTRACT In this large randomized trial among callers to the Cancer Information Service (CIS), tailored print materials were tested for efficacy in promoting colorectal cancer (CRC) screening (fecal occult blood test [FOBT], flexible sigmoidoscopy, or colonoscopy). All participants completed baseline interviews at the end of their usual service calls to the CIS, as well as short-term (6-month) and longer-term (14-month) telephone follow-up interviews. The study sample (n = 4,014) was restricted to English-speaking CIS callers 50 + years of age, who would be eligible for CRC screening at 14 months follow-up and did not call the CIS about CRC or CRC screening. Four experimental conditions were compared: a single untailored (SU) mailout of print material (the control condition); a single tailored (ST) mailout of print material; four (multiple) tailored (MT) mailouts of print materials spanning 12 months, all of which were tailored to information obtained at baseline; and four (multiple) retailored (MRT) mailouts also spanning 12 months, with retailoring of the print materials (mailouts 2, 3, and 4) based on updated information obtained from the 6-month follow-up interviews. Consistent with the main hypothesis of this trial, a significant linear trend across the SU, ST, MT, and MRT groups was found at 14 months (42%, 44%, 51%, and 48%, respectively, p = 0.05). Only for MT was there a significant difference compared with SU (p = 0.03) for the sample as a whole, while no differences were found for MT vs. MRT at 14 months. Significant moderator effects in the predicted direction were found among females, younger participants, and among those with a history of CRC screening, all of which involved the SU vs. MT MRT comparisons. Only among younger participants (ages 50–59) was there a difference between SU vs. ST at 14 months. Given these results, we conclude from this trial the following: (1) the MRT intervention failed to show added benefit beyond the MT intervention, (2) the significant intervention effects involving the MT and MRT conditions can be explained by tailoring and/or the longitudinal nature of both interventions, and (3) the most compelling evidence in support of tailoring was found for the ST condition among younger participants, where a significant need for interventions exists at the national level. Directions for future research are discussed in light of the results summarized above.

OBJECTIVES This study evaluates the efficacy of two interventions designed to reduce loss-to-follow-up among women with abnormal Pap smears. METHODS The two interventions were evaluated in two large public hospitals using a randomized 2 x 2 factorial design. One intervention involved an intensive follow-up protocol that relied on multiple attempts (mail and telephone) to contact the patient. The second intervention provided patients with economic vouchers to offset out-of-pocket expenses associated with the follow-up visits. Loss-to-follow-up was addressed by medical chart reviews and telephone interviews. RESULTS The study population (n = 1453) was primarily Hispanic, married or otherwise living with a significant other, relatively young in age, and with no source of payment for health care. Overall, 30% of the total sample was loss-to-follow-up (i.e., no return visits). Among patients assigned to the control condition, loss-to-follow-up was 36.1% compared with 27.8% for the intensive follow-up condition, 28.8% for the voucher condition, and 29.0% for the intensive follow-up plus voucher condition. Both intervention conditions significantly improved follow-up rates. The odds ratio for intensive follow-up was 1.56 compared with 1.50 for the voucher intervention. The combined intervention condition (intensive follow-up x voucher program) did not have a significant effect after taking into account the main effects of the two interventions. Correlates of loss-to-follow-up included age (younger women had lower return rates), race/ethnicity (African American women had lower return rates), live-in relationship (women who were not married or living as married had lower return rates), and severity of the abnormal Pap smear (less severe abnormalities were associated with lower return rates). CONCLUSIONS Both interventions were associated with moderate reductions in loss-to-follow-up in this underserved population. The implications of these findings are discussed relative to implementing cervical cancer control programs within state and local health departments.
