Evaluation of Three Postal Invitational Strategies to Increase Survey Response Rates in a Combat-Injured U.S. Military Population: Findings From the Wounded Warrior Recovery Project.

The survival rate of those injured in combat in overseas contingency operations is higher than in previous conflicts. There is a need to assess the long-term psychosocial and quality of life outcomes of those injured in combat, yet surveying this population presents inherent challenges. As part of a large-scale, longitudinal examination of patient-reported outcomes of service members injured on deployment, the present manuscript evaluated the effectiveness of three postal strategies on response rates: (1) mailing a study prenotification postcard, (2) mailing the survey invitation in a larger envelope, and (3) including a small cash preincentive ($2). Evaluation of these strategies yielded mixed results in this population. Neither the prenotification postcard nor inclusion of a $2 cash preincentive significantly increased response rates. However, use of a larger envelope to mail the survey invitation significantly increased the response rate by 53.1%. Researchers interested in collecting patient-reported outcomes among military populations, including those with combat-related injuries, may find that increasing the visibility of recruitment materials is more effective for improving response rates than attempting to cognitively prime or offer prospective participants preincentives.

Receipt of Tobacco Direct Mail Coupons and Changes in Smoking Status in a Nationally Representative Sample of US Adults.

Introduction: Direct-to-consumer tobacco marketing, including direct mail and email coupons, is a potentially influential marketing strategy. We examined the associations between receipt of tobacco direct mail/email coupons and trajectories of smoking behavior among US adults. Methods: Data were from the US Population Assessment on Tobacco and Health (PATH) Study adult sample (n = 32160) collected during 2013-2014. Participants self-reported their smoking status (every day, some days, not at all) 12 months prior to the survey (T0) and at the time of the survey (T1). Three smoking trajectories were identified: nonsmokers progressing to current smokers, current smokers continuing to smoke, and among current smokers at T0, progressing to or continuing with daily smoking. Participants also reported receipt of direct mail/email tobacco coupons in the 6 months preceding T1 (yes/no). Weighted multiple logistic regression models were used to test the associations between receiving direct mail/email tobacco coupons and different smoking trajectories adjusted for demographic characteristics. Results: One in eight (12.4%) US adult nonsmokers and 36.2% adult smokers at T0 reported receiving tobacco coupons. Receipt of tobacco coupons was negatively associated with poverty status. Receipt of tobacco coupons was associated with increased odds of progression to current smoking (AOR = 1.76, 95% CI = 1.45 to 2.12), continuation of smoking (AOR = 1.34, 95% CI = 1.09 to 1.65), and current smokers' progression to or continuation with daily smoking (AOR = 1.70, 95% CI = 1.50 to 1.91). Conclusions: Direct-to-consumer tobacco coupons may promote progression of smoking among nonsmokers, and continuation of smoking and progression to daily smoking among smokers in US adults. Implications: Distributing direct mail coupons is a strategy employed by tobacco companies to promote their products. We found, in a US national study, that many adults received tobacco coupons, and receiving these coupons was associated with subsequent progression of smoking among nonsmokers, and continuation of smoking and daily smoking among smokers. Scrutiny over the use of direct mail coupons and its effects on population health is warranted. Future research is needed to evaluate the effect of different interventions to reduce the impact of these coupons on smoking behaviors.

The Experience of Direct Outreach Recruitment in the National Children's Study.

OBJECTIVE: Few studies have reported the outcome of direct outreach methods for recruitment of research participants in population-based samples. We describe the relationship of outreach strategies that are tailored to specific community factors to recruitment and consent outcomes in 10 National Children's Study direct outreach study locations (all were single counties). METHODS: Each study center collected data from a target population of women who resided in selected county segments that were sampled based on a geographic area probability sampling design. Based on county characteristics of the 10 study locations, each study center used site-specific marketing approaches (direct mail, mass media, provider referrals, social networking) to recruit study participants. Recruitment success was measured by the number of recruited women as well as by a qualitative assessment of the effectiveness of various recruitment methods. RESULTS: The number of women who consented varied from 67 to 792. The majority of women were pregnant at the time of consent. Community awareness varied from <1% to 70%. Although no significant associations were found between community characteristics and recruitment success, we found that certain types of outreach strategies enhanced recruitment. CONCLUSIONS: In a small sample of 10 US counties, recruitment success was not associated with community characteristics. It was, however, associated with certain types of outreach strategies that may be more effective in close-knit communities.

Patterns of use and expenses associated with mail-service pharmacy in adults with diabetes.

OBJECTIVES: To identify socioeconomic factors associated with mail-service pharmacy use and compare the differences in disease-specific prescription medication and medical utilization expenses in a nationally representative sample of adults with diabetes. DESIGN: A retrospective, longitudinal, cross-sectional study. SETTING: United States in 2006-11. PARTICIPANTS: Medical Expenditure Panel Survey household component (MEPS-HC) participants aged 18 years or older diagnosed with diabetes and prescribed antidiabetic medications. MAIN OUTCOME MEASURES: Likelihood of mail-service pharmacy use, diabetes-related medical utilization, and medication expenses. RESULTS: Among 4,430 eligible participants identified in the 2006-11 surveys, representing more than 83 million U.S. individuals, nearly 13% of the participants obtained two-thirds or more of their antidiabetic medications via mail service predominantly. Mail-service pharmacy users were older, had high school or college degrees, had higher incomes, and were more likely to be covered by private insurance. There were no significant differences in diabetes-related medical utilization and drug expenses between the two groups. CONCLUSION: Besides pharmacy benefit design, sociodemographic and economic factors influenced drug dispensing channel use (mail service versus community pharmacy). No significant differences in diabetes-related drug and medical expenses between mail-service and community pharmacy users were observed.

Web-based questionnaires: the future in epidemiology?

The traditional epidemiologic modes of data collection, including paper-and-pencil questionnaires and interviews, have several limitations, such as decreasing response rates over the last decades and high costs in large study populations. The use of Web-based questionnaires may be an attractive alternative but is still scarce in epidemiologic research because of major concerns about selective nonresponse and reliability of the data obtained. The authors discuss advantages and disadvantages of Web-based questionnaires and current developments in this area. In addition, they focus on some practical issues and safety concerns involved in the application of Web-based questionnaires in epidemiologic research. They conclude that many problems related to the use of Web-based questionnaires have been solved or will most likely be solved in the near future and that this mode of data collection offers serious benefits. However, questionnaire design issues may have a major impact on response and completion rates and on reliability of the data. Theoretically, Web-based questionnaires could be considered an alternative or complementary mode in the range of epidemiologic methods of data collection. Practice and comparisons with the traditional survey techniques should reveal whether they can fulfill their expectations.
