Abstract
HINTERGRUND UND ZIELE Durch die Entwicklung neuer anti-psoriatischer Medikamente und verbesserte Strukturen zu deren flächendeckender Einführung hat sich die medizinische Versorgung von Psoriasis-Patienten deutlich verbessert. In dieser Studie haben wir die tatsächliche Inanspruchnahme des Gesundheitswesens untersucht und Gründe für die Unzufriedenheit der Betroffenen ermittelt. PATIENTEN UND METHODIK Diese nicht-interventionelle Querschnittsstudie wurde als anonyme Online-Befragung von 12/2018 bis 01/2019 in Deutschland durchgeführt. Teilnehmer mit einer selbstberichteten, von einem Arzt gestellten Psoriasis-Diagnose und Symptomen beantworteten Fragen zu ihrer Erkrankung, deren Einfluss auf das tägliche Leben und ihrer medizinischen Versorgung. ERGEBNISSE 649 Teilnehmer mit einem mittleren Alter von 42,5 ± 13,7 Jahren und ausgewogener Geschlechterverteilung (männlich: 50,2 %) wurden ausgewertet. 54,1 % waren zum Zeitpunkt der Studie in ärztlicher Behandlung, 45,9 % nicht. Von den Teilnehmern mit medizinischer Versorgung waren 59,3 % nur mäßig oder weniger zufrieden mit ihrer Behandlung. Gründe für die Unzufriedenheit mit der Medikation waren unter anderem mangelnde Wirksamkeit und Nebenwirkungen. Von den nicht in ärztlicher Behandlung befindlichen Teilnehmern wurde "Zeitmangel des Arztes" als Hauptgrund für die Nichtinanspruchnahme ärztlicher Hilfe angegeben. SCHLUSSFOLGERUNGEN Trotz der Verfügbarkeit effizienter Therapieoptionen in Deutschland sind viele Betroffene mit Psoriasis unzufrieden. Diese unterbehandelte Gruppe wurde als neue Zielgruppe identifiziert.

Abstract
BACKGROUND AND OBJECTIVES Due to the development of new anti-psoriatic drugs in combination with improved structures for implementation throughout Germany, the medical care of psoriasis patients has markedly improved. In this study we investigated the real-life utilization of the health care system and identified reasons for dissatisfaction in affected individuals. PATIENTS AND METHODS This non-interventional cross-sectional study was conducted as an anonymous online survey from 12/2018 to 01/2019 in Germany. Participants with a self-reported physician-confirmed diagnosis of psoriasis and symptoms answered questions about their disease, its influence on daily life and their medical care. RESULTS 649 participants with a mean age of 42.5 ± 13.7 years and equal gender distribution (male: 50.2 %) were evaluated. 54.1 % received medical treatment at the time of the study, 45.9 % did not. Among the participants with medical care, 59.3 % were only moderately or less satisfied with their treatment. Reasons for dissatisfaction with the medication included lack of efficacy and side effects. Participants without medical treatment specified a physician's lack of time as a main reason for not seeking medical help. CONCLUSIONS Despite the availability of efficient therapeutic options in Germany, many individuals with psoriasis are not satisfied. This under-treated group was identified as a new target population.

Abstract
OBJECTIVE To assess handling techniques commonly used during routine examinations and procedures used for calm, fearful, and aggressive cats by veterinarians and nonveterinarian staff at Canadian and US veterinary practices and to evaluate demographic factors associated with those handling techniques. SAMPLE 310 veterinarians and 944 nonveterinarians who handle cats at Canadian and US veterinary practices. PROCEDURES An online questionnaire was developed to evaluate respondent demographics and use of common cat handling practices and techniques. A snowball sampling method was used to send a link to the questionnaire to members of Canadian and US veterinary-affiliated groups. Descriptive statistics were generated; logistic regression was used to identify demographic factors associated with the use of minimal and full-body restraint with scruffing during routine examination and procedures for fearful and aggressive cats. RESULTS Full-body restraint was used to handle cats of all demeanors, although its frequency of use was greatest for fearful and aggressive cats. Veterinarians and nonveterinarians who graduated from veterinary training programs before 2006 were less likely to use full-body restraint for cats of all demeanors, compared with nonveterinarians who did not graduate or graduated between 2006 and 2015. Other factors associated with decreased use of full-body restraint included working at an American Association of Feline Practitioners-certified practice and working at a Canadian practice. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that full-body restraint is commonly used to handle cats. Further research is necessary to determine whether current handling recommendations are effective in decreasing stress for cats during veterinary visits.

"How do online and offline sampling compare in a multinational study of drug use and nightlife behaviour?". THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 82:102812. [PMID: 32554209 DOI: 10.1016/j.drugpo.2020.102812] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Revised: 05/13/2020] [Accepted: 05/28/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Online sampling is widely used to recruit hard to reach samples such as drug users at nightlife events. We conducted the first study comparing differences in demographics, drug use and nightlife behaviour between an online sample of young adults engaging with the European nightlife scene, and an offline sample recruited at nightclubs and festivals in Europe. METHODS Online participants who attended at least six nightlife events in the past 12 months were recruited using social media advertising (May-November 2017). Offline participants were recruited at nightclubs and festivals using a random intercept method (May-November 2017). Samples were compared with respect to age, gender, past year use of alcohol, cannabis, cocaine, ecstasy/MDMA and amphetamines, and past year attendance at nightclubs, licensed festivals, illegal festivals, pubs and house-parties. RESULTS 6153 online and 3529 offline participants were recruited. When adjusting for differences in age and gender, online participants were less likely to have used each drug and to have attended illegal festivals, pubs and house-parties in the past 12 months. The online sample also used each drug and attended each venue, with the exception of nightclubs, less frequently on average than offline participants. Adjusted odds ratios (range 0.37 to 1.39) and regression coefficients (range -0.84 to 0.07) indicate that the majority of observed differences between the samples were of a small effect size. CONCLUSIONS Estimates of drug use and nightlife engagement are more conservative when using online sampling compared to venue based sampling. Observed differences were generally small in effect, indicating good overall representativeness when using online sampling in the European nightlife scene.

Abstract
Background Degenerative cervical myelopathy (DCM) is a common, chronic neurological condition that severely affects individuals by causing a range of disabling symptoms, frequently at a time around the peak of their careers. Subsequently, individuals with DCM often become dependent on informal care arrangements. The significant economic contribution of informal care and its burden on care providers are becoming increasingly recognized. Objective This study aimed to measure the quality of life of DCM informal caregivers and provide preliminary insight into possible contributing factors. Methods Carers of individuals with DCM completed a Web-based survey hosted by Myelopathy.org, an international DCM charity. Carer quality of life was assessed in the form of caregiver happiness and 7 dimensions of carer burden using the Care-Related Quality of Life (CarerQol) instrument. The relationships between patient disease severity, patient pain, and carer quality of life were investigated. Differences in carer quality of life were assessed across patient and carer demographic groups, including between UK and US carers. Results DCM caregivers experienced substantial burden as a result of their caregiving (mean CarerQol-7D=64.1; 95% CI 58.8-69.5) and low happiness (mean CarerQol-VAS [Visual Analog Scale]=6.3; 95% CI 5.7-6.9). Burden was high and happiness was low in DCM carers when compared with a large, mixed-disease study of adult informal carers where CarerQol-7D was 79.1 and CarerQol-VAS was 7.1. No significant relationship was found between DCM carer quality of life and patient disease severity and pain scores. DCM carer quality of life appeared uniform across all patient and carer demographic groups. Conclusions Caring for individuals with DCM is associated with reduced quality of life in the form of significant burden and reduced happiness. Reductions appear greater in DCM than in other diseases investigated. However, no simple relationship was identified between individual patient or carer factors and carer quality of life.

Res Nurs Health 2019; 42:458-466. [PMID: 31400022 DOI: 10.1002/nur.21976] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Accepted: 07/17/2019] [Indexed: 01/08/2023]
Abstract
Surveys represent one of the most common and useful ways to collect self-reported data on a wide variety of topics and from a diversity of respondents, including health care providers (HCPs). Unfortunately, survey response rates have been declining for decades; surveys with HCPs often yield response rates of 40% or less. Another major challenge in surveys with HCPs arises from difficulties in identifying appropriate sampling frames. The lack of appropriate sampling frames is particularly problematic when trying to survey multiple types of HCPs or those who work in unusual practice settings or specialties. The purpose of this paper is to describe the current challenges to survey research with college HCPs who are members of multidisciplinary care teams, and propose alternative approaches to sampling and data collection. An exemplar is provided in which three different approaches to sampling, recruitment and data collection were undertaken with a multidisciplinary sample of college HCPs. The three approaches are compared in terms of response rates, costs, and sample characteristics. Differences were noted in effort, response rates, and sample characteristics. Respondents recruited from professional organization mailing lists were disproportionately from smaller, private college/universities, as compared with those recruited from colleges/universities selected from a U.S. Department of Education list. However, no differences in variables of interest were found between the three samples, reducing concerns of potential bias. Developing best practices for surveying multiple types of HCPs will become increasingly important as we seek to better understand current care processes and plan implementation studies to promote the adoption of practice recommendations.

Abstract
BACKGROUND There is increasing use of online surveys to improve data quality and timeliness and reduce costs. While there have been numerous cross-sectional studies comparing responses to online or paper surveys, there is little research from a longitudinal perspective. OBJECTIVE In the context of the well-established Australian Longitudinal Study on Women's Health, we examined the patterns of responses to online or paper surveys across the first two waves of the study in which both modes were offered. We compared the following: differences between women born between 1946 and 1951 and between 1973 and 1978; types of device used for online completion; sociodemographic, behavioral, and health characteristics of women who responded online or using mailed paper surveys; and associations between mode of completion in the first survey and participation and mode of completion in the second survey. METHODS Participants in this study, who had responded to regular mailed surveys since 1996, were offered a choice of completing surveys using paper questionnaires or Web-based electronic questionnaires starting in 2012. Two groups of women were involved: an older cohort born between 1946 and 1951 aged in their 60s and a younger cohort born between 1973 and 1978 aged in their 30s when the online surveys were first introduced. We compared women who responded online on both occasions, women who responded online at the first survey and used the paper version of the second survey, women who changed from paper to online, and those who used paper for both surveys. RESULTS Of the 9663 women in their 60s who responded to one or both surveys, more than 50% preferred paper surveys (5290/9663, 54.74%, on the first survey and 5373/8621, 62.32%, on the second survey). If they chose the online version, most used computers. In contrast, of the 8628 women in their 30s, 56.04% (4835/8628) chose the online version at the first survey. While most favored computers to phones or tablets, many did try these alternatives on the subsequent survey. Many women who completed the survey online the first time preferred the paper version on the subsequent survey. In fact, for women in their 60s, the number who went from online to paper (1151/3851, 29.89%) exceeded the number who went from paper to online (734/5290, 13.88%). The online option was more likely to be chosen by better educated and healthier women. In both cohorts, women who completed paper surveys were more likely than online completers to become nonrespondents on the next survey. Due to the large sample size, almost all differences were statistically significant, with P<.001. CONCLUSIONS Despite the cost-saving advantages of online compared to paper surveys, paper surveys are likely to appeal to a different population of potential respondents with different sociodemographic, behavioral, and health characteristics and greater likelihood of attrition from the study. Not offering a paper version is therefore likely to induce bias in the distribution of responses unless weighting for respondent characteristics (relative to the target population) is employed. Therefore, if mixed mode (paper or online) options are feasible, they are highly likely to produce more representative results than if only the less costly online option is offered.

Abstract
BACKGROUND Text messaging interventions have shown promise in helping people quit smoking. Texting programs periodically survey participants about their smoking status. This study examined the consistency of participant self-reported smoking between external surveys and internal program text message assessments. METHODS Participants in Text2Quit program were surveyed about their past 7-day smoking at one, three, and six months post-enrollment using different survey modes (external surveys and internal program text message assessments) and responses were compared for consistency. The first set of analyses was conducted for participants responding on both modes (n = 45 at one month; n = 50 at three months; n = 42 at six months). Additional analyses, assuming missing = smoking, were conducted with the full sample of 262 smokers (68.7% female, mean age = 35.8 years) and compared to saliva-confirmed abstinence rates. RESULTS Participants responding to both modes consistently reported smoking status at one (88.9%), three (88.0%) and six (88.1%) months post-enrollment, with fair to substantial levels of agreement (one month: κ = 0.24; three months: κ = 0.63; six months: κ = 0.66). Participants responding to both modes reported high rates of abstinence. In missing = smoking analyses, significant differences in abstinence rates reported across modes were detected at each timepoint (one month: external = 30.5%, internal = 16.4%; three months: external = 33.2%, internal = 16.0%; six months: external = 31.7%, internal = 12.2%; all p < .001). Moderate levels of agreement were found between the two modes. At 6 months, abstinence rates obtained via internal data were closer to those biochemically verified (15.7%) compared to external surveys. CONCLUSIONS Results provide initial support for the use of internal program assessments in text messaging programs with missing = smoking assumptions in order to gather outcome data on smoking behavior.

Abstract
Background Use of community volunteers to support vulnerable families is a widely employed strategy with a long history. However, there has been minimal formal scientific investigation into the effectiveness of volunteer home visiting programs for families. There is also a need for research examining whether volunteer home visiting leads to improved outcomes for volunteers. Objective The objective of this paper is to describe the research protocol for a pragmatic randomized controlled trial (RCT) of the Volunteer Family Connect intervention, a volunteer home visiting program designed to support families of young children who experience social isolation or a lack of parenting confidence and skills. The project is being conducted in partnership with 3 leading not-for-profit organizations, designed to contribute to the body of evidence that informs decisions about appropriate family support services according to the level of need. It is the first study to examine outcomes for both the families and the volunteers who deliver the service. Methods The RCT is being conducted in 7 sites across Australia. We aim to recruit 300 families to the study: 150 control (services as usual) and 150 intervention (services as usual + volunteer home visiting) families. Intervention families will receive the service for 3-12 months according to their needs, and all participants will complete 6 data collection points over 15 months. A minimum of 80 volunteers will also be recruited, along with a matched community comparison group. The volunteers will complete 3 data collection points over 12 months. Primary outcomes include community connectedness and parenting competence. Secondary outcomes include parent physical and mental health; general parent well-being; parent empowerment; the child-parent relationship; sustainability of family routines; child immunization; child nutrition or breastfeeding; number of accidental injury reports; and volunteer health, well-being, and community connectedness. Results This effectiveness trial was funded in 2016, and we aim to complete data collection by the end of 2018. The first results are expected to be submitted early in 2019. Conclusions There is a need to rigorously assess volunteer home visiting and whether it has a unique and important role on the service landscape, complementary to professional services. This research is the first trial of a volunteer home visiting program to be conducted in Australia and one of the largest of its kind worldwide.

Mode Equivalence of Health Indicators Between Data Collection Modes and Mixed-Mode Survey Designs in Population-Based Health Interview Surveys for Children and Adolescents: Methodological Study. J Med Internet Res 2018; 20:e64. [PMID: 29506967 PMCID: PMC5859740 DOI: 10.2196/jmir.7802] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Revised: 10/14/2017] [Accepted: 11/16/2017] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects). OBJECTIVE This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups. METHODS Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs-a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)-and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed. Sociodemographic characteristics and a broad range of health indicators for children and adolescents were compared by survey design and data collection mode by calculating predictive margins from regression models. RESULTS There were no statistically significant differences in sociodemographic characteristics or health indicators between the single-mode control group and any of the mixed-mode survey designs. Differences in sociodemographic characteristics between SAQ-Web and SAQ-paper were found. Web respondents were more likely to be male, have higher levels of education, and higher household income compared with paper respondents. After adjusting for sociodemographic characteristics, only one of the 38 analyzed health indicators showed different prevalence rates between the data collection modes, with a higher prevalence rate for lifetime alcohol consumption among the online-responding adolescents (P<.001). CONCLUSIONS These results suggest that mode bias is limited in health interview surveys for children and adolescents using a mixed-mode design with Web-based and paper questionnaires.

Ebert JF, Huibers L, Christensen B, Christensen MB. Paper- or Web-Based Questionnaire Invitations as a Method for Data Collection: Cross-Sectional Comparative Study of Differences in Response Rate, Completeness of Data, and Financial Cost. J Med Internet Res 2018; 20:e24. [PMID: 29362206 PMCID: PMC5801515 DOI: 10.2196/jmir.8353] [Citation(s) in RCA: 175] [Impact Index Per Article: 29.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Revised: 10/12/2017] [Accepted: 11/16/2017] [Indexed: 11/27/2022] Open
Abstract
Background Paper questionnaires have traditionally been the first choice for data collection in research. However, declining response rates over the past decade have increased the risk of selection bias in cross-sectional studies. The growing use of the Internet offers new ways of collecting data, but trials using Web-based questionnaires have so far seen mixed results. A secure, online digital mailbox (e-Boks) linked to a civil registration number became mandatory for all Danish citizens in 2014 (exemption granted only in extraordinary cases). Approximately 89% of the Danish population have a digital mailbox, which is used for correspondence with public authorities. Objective We aimed to compare response rates, completeness of data, and financial costs for different invitation methods: traditional surface mail and digital mail. Methods We designed a cross-sectional comparative study. An invitation to participate in a survey on help-seeking behavior in out-of-hours care was sent to two groups of randomly selected citizens from age groups 30-39 and 50-59 years and parents to those aged 0-4 years using either traditional surface mail (paper group) or digital mail sent to a secure online mailbox (digital group). Costs per respondent were measured by adding up all costs for handling, dispatch, printing, and work salary and then dividing the total figure by the number of respondents. Data completeness was assessed by comparing the number of missing values between the two methods. Socioeconomic variables (age, gender, family income, education duration, immigrant status, and job status) were compared both between respondents and nonrespondents and within these groups to evaluate the degree of selection bias. Results A total 3600 citizens were invited in each group; 1303 (36.29%) responded to the digital invitation and 1653 (45.99%) to the paper invitation (difference 9.66%, 95% CI 7.40-11.92). The costs were €1.51 per respondent for the digital group and €15.67 for paper group respondents. Paper questionnaires generally had more missing values; this was significant in five of 17 variables (P<.05). Substantial differences were found in the socioeconomic variables between respondents and nonrespondents, whereas only minor differences were seen within the groups of respondents and nonrespondents. Conclusions Although we found lower response rates for Web-based invitations, this solution was more cost-effective (by a factor of 10) and had slightly lower numbers of missing values than questionnaires sent with paper invitations. Analyses of socioeconomic variables showed almost no difference between nonrespondents in both groups, which could imply that the lower response rate in the digital group does not necessarily increase the level of selection bias. Invitations to questionnaire studies via digital mail may be an excellent option for collecting research data in the future. This study may serve as the foundational pillar of digital data collection in health care research in Scandinavia and other countries considering implementing similar systems.

The effects of using answer sheets on reported drug use and data quality in a classroom survey: A cluster-randomized study. Drug Alcohol Depend 2017; 178:194-200. [PMID: 28654872 PMCID: PMC5548613 DOI: 10.1016/j.drugalcdep.2017.05.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Revised: 05/01/2017] [Accepted: 05/05/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND We compare self-reported prevalence of drug use and indicators of data quality from two different response modes (with and without an independent answer sheet for recording responses) in a survey conducted in 2015 among secondary school students. METHODS Stratified cluster-randomized study conducted among students in grades 8-12 from public, private and subsidized schools in Chile (N=2317 students in 122 classes). Measurements included were: percentage reporting substance use (tobacco, alcohol, marijuana, cocaine, ecstasy); number of inconsistent responses; number of item nonresponses; percentage of extreme reports of drug use; percentage reporting using the nonexistent drug, relevón; and completion times. RESULTS Compared with those who responded directly in the questionnaire booklet, students who used a separate answer sheet took 17.6 more minutes (95% confidence interval [CI]: 14.4-20.8) to complete the survey and had on average 1.5 more inconsistent responses (95%CI: 0.91-2.14). The prevalence and variance of drug use was higher among those who used an answer sheet for all substances except tobacco; the prevalence ratio (PR) of reported substance use for low-prevalence substances during the past year were: cocaine PR=2.5 (95%CI: 1.6-4.1); ecstasy PR=5.0 (95%CI: 2.4-10.5); relevón PR=4.8 (95%CI: 2.5-9.3). CONCLUSIONS Using an answer sheet for a self-administered paper-and-pencil survey of drug use among students result in lower quality data and higher reports of drug use. International comparison of adolescent drug use from school-based surveys should be done with caution. The relative ranking of a country could be misleading if different mode of recording answers are used.

Abstract
Background Increasing availability of the Internet allows using only online data collection for more epidemiological studies. We compare response patterns in a population-based health survey using two survey designs: mixed-mode (choice between paper-and-pencil and online questionnaires) and online-only design (without choice). Methods We used data from a longitudinal panel, the Hygiene and Behaviour Infectious Diseases Study (HaBIDS), conducted in 2014/2015 in four regions in Lower Saxony, Germany. Individuals were recruited using address-based probability sampling. In two regions, individuals could choose between paper-and-pencil and online questionnaires. In the other two regions, individuals were offered online-only participation. We compared sociodemographic characteristics of respondents who filled in all panel questionnaires between the mixed-mode group (n = 1110) and the online-only group (n = 482). Using 134 items, we performed multinomial logistic regression to compare responses between survey designs in terms of type (missing, “do not know” or valid response) and ordinal regression to compare responses in terms of content. We applied the false discovery rates (FDR) to control for multiple testing and investigated effects of adjusting for sociodemographic characteristic. For validation of the differential response patterns between mixed-mode and online-only, we compared the response patterns between paper and online mode among the respondents in the mixed-mode group in one region (n = 786). Results Respondents in the online-only group were older than those in the mixed-mode group, but both groups did not differ regarding sex or education. Type of response did not differ between the online-only and the mixed-mode group. Survey design was associated with different content of response in 18 of the 134 investigated items; which decreased to 11 after adjusting for sociodemographic variables. In the validation within the mixed-mode, only two of those were among the 11 significantly different items. The probability of observing by chance the same two or more significant differences in this setting was 22%. Conclusions We found similar response patterns in both survey designs with only few items being answered differently, likely attributable to chance. Our study supports the equivalence of the compared survey designs and suggests that, in the studied setting, using online-only design does not cause strong distortion of the results.

Abstract
BACKGROUND Persons with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolism. We sought to examine whether the self-report of hormonal contraception (HC), as a proxy for exposure to estrogen-based contraception, was less common for women with multiple risk factors for venous thromboembolism. METHODS We examined the prevalence of personal use of hormonal birth control in a large internet-based cohort of patients with IBD. To determine whether HC was less common among patients with IBD with increased risk of thrombosis, we estimated unadjusted and adjusted prevalence ratios (PRs) for the use of HC. RESULTS Thousand four hundred ninety-nine female survey respondents answered optional fertility questions and were included in the analysis. The prevalence of HC was 33.7% (95% CI, 30.6%-36.9%) among women with Crohn's disease and was 32.6% (95% CI, 28.6%-36.8%) for women with ulcerative colitis. Women with one risk factor for thrombosis were not significantly less likely to receive HC (PR = 0.91, 95% CI: 0.76-1.08; adjusted PR = 0.94, 95% CI: 0.80-1.11) compared with women without risk factors nor were women with 2 or more risk factors (PR = 1.10, 95% CI 0.56-1.28; adjusted PR = 1.10, 95% CI: 0.83-1.45). The use of an intrauterine device was also similar between women with and without risk factors for venous thromboembolism. CONCLUSIONS The prevalence of HC use in women with multiple risk factors was similar to that in women without risk factors, which represents an opportunity for prevention. Gastroenterologists should ask patients with IBD using HC about risk factors for thromboembolic disease to identify patients who may benefit from alternative contraception.

Abstract
Background A key challenge for longitudinal cohort studies is follow-up and retention of study participants. Participant follow-up in longitudinal cohort studies is costly and time-consuming for research staff and participants. Objective This study determined the feasibility and costs of using Web-based technologies for follow-up and collection of patient-reported outcomes in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study. Methods The MASALA study is a community-based cohort of 906 South Asians in the United States. Since the baseline in-person visits (2010-2013), a yearly telephone follow-up survey was used to assess participants’ health status and incidence of cardiovascular disease. A Web-based version of the follow-up survey was developed using the REDCap (Research Electronic Data Capture) Web app. Participants from the Chicago field center who were due for their annual follow-up and who had a valid email address were sent an email link to a secure online portal where they could complete the survey. Telephone follow-up was used with nonresponders. Results A link to the Web survey was emailed to 285 participants (February to October 2014) and the overall completion rate was 47.7% (136/285). One-third of participants who were unresponsive (n=36) to annual telephone follow-up completed the Web survey. Web responders were younger, more likely to be married, and to have higher education and income compared (P<.05) to telephone-only responders. Web survey development involved 240 hours of research staff time. Since launching, the Web-based survey has required 3 hours per week of staff time. Conclusions Although electronic follow-up will not be a panacea for cohort operations, it will serve as an adjunctive strategy to telephonic follow-up for maximizing cohort retention with lower costs.

Abstract
ABSTRACT This study describes the use of online questionnaires and their virtual dissemination as a data collection strategy in Germany. The online questionnaire was elaborated using a virtual platform, creating a link that was disseminated in virtual environments. Participants were 100 Germans with Spina Bifida; 149 people visited the link, 83 of them coming from virtual forums, 27 from emails, 26 from social networks, ten from the German association of spina bifida site and three from the university website. With 55.7% of the participants, the virtual forum was the most agile dissemination medium to capture the data. This data collection mode should be used in future research, involving different countries, due to the speed, saving, good use of answers and help to overcome the language barrier. Public policies that support people's access to the Internet are necessary, so that these studies can be conducted successfully.

Abstract
BACKGROUND While Medicare Part D was signed into law in 2003 and initiated in 2006, there is a scarcity of information related to the implications of Part D on community pharmacies and subsequent effects. OBJECTIVE To determine the financial implications of Part D on community pharmacy, to identify pharmacists' and beneficiaries concerns from the pharmacists' perspective and to determine the pharmacists' responses to these impactions and concerns. METHODS A cross-sectional survey of pharmacists practicing in six states (Maine, New Jersey, New York, Maryland, Massachusetts and Pennsylvania) was conducted online between June and December 2011. The 37-question online survey collected demographic data, data about implications of Part D on community pharmacy and patients, and pharmacists' beliefs about ideal pharmacy practice and Part D plans. RESULTS Of the 4,888 online surveys, only 1,108 were assumed to have reached the intended recipients (response rate 25 %). Fifty-six percent reported that reimbursement was the most significant concern, and 34.5 % of the owners or part-owners were planning to close their pharmacy due to financial pressures exerted by Part D. A significant relationship was observed between dispensing of 90 days' supply of medications and better financial performance (χ (2) = 6.95, p = 0.0084). The most significant patient concerns were formulary and copayment (52.8 %) and Donut hole (52.4 %). Fifty-four percent respondents stated that his/her pharmacy helped patients obtain financial assistance while patients were in the Donut hole. CONCLUSION Respondents were most concerned about the poor reimbursement rates, but pharmacists who dispensed 90 day supply of medications reported acceptable financial performance. Pharmacists also reported helping patients obtain financial assistance while in the Donut hole.

Response rates for patient-reported outcomes using web-based versus paper questionnaires: comparison of two invitational methods in older colorectal cancer patients. J Med Internet Res 2015; 17:e111. [PMID: 25953059 PMCID: PMC4468744 DOI: 10.2196/jmir.3741] [Citation(s) in RCA: 70] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2014] [Revised: 01/22/2015] [Accepted: 02/15/2015] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Improving questionnaire response rates is an everlasting issue for research. Today, the Internet can easily be used to collect data quickly. However, collecting data on the Internet can lead to biased samples because not everyone is able to access or use the Internet. The older population, for example, is much less likely to use the Internet. The Patient-Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) registry offers a platform to collect Web-based and paper questionnaires and to try different measures to improve response rates. OBJECTIVE In this study, our aim was to study the influence of two methods of invitation on the response rate. Our second aim was to examine the preference of questionnaire mode of administration (paper or Web-based) for the older patient in particular. METHODS To test these two invitational methods, 3406 colorectal cancer patients between ages 18 and 85 years received an invitation containing an access code for the Web-based questionnaire. They could also request a paper questionnaire with an included reply card (paper-optional group). In contrast, 179 randomly selected colorectal cancer patients received a paper questionnaire with the invitation (paper-included group). They could also choose to fill out the Web-based questionnaire with the included access code. RESULTS Response rates did not differ between the paper-optional and the paper-included groups (73.14%, 2491/3406 and 74.9%, 134/179, P=.57). In the paper-optional group, online response was significantly higher when compared to the paper-included group (41.23%, 1027/2491 vs 12.7%, 17/134, P<.001). The majority of online respondents responded after the first invitation (95.33%, 979/1027), which was significantly higher than the paper respondents (52.19%, 764/1464, P<.001). Respondents aged 70 years and older chose to fill out a paper questionnaire more often (71.0%, 677/954). In the oldest age group (≥80 years), 18.2% (61/336) of the respondents filled out a Web-based questionnaire. CONCLUSIONS The lack of difference in response rates between invitation modes implies that researchers can leave out a paper questionnaire at invitation without lowering response rates. It may be preferable not to include a paper questionnaire because more respondents then will fill out a Web-based questionnaire, which will lead to faster available data. However, due to respondent preference, it is not likely that paper questionnaires can be left out completely in the near future.

Abstract
OBJECTIVE We aimed to compare data quality from online and postal questionnaires and to evaluate the practicality of these different questionnaire modes in a cancer sample. METHODS Participants in a study investigating the psychosocial sequelae of testicular cancer could choose to complete a postal or online version of the study questionnaire. Data quality was evaluated by assessing sources of nonobservational errors such as participant nonresponse, item nonresponse and sampling bias. Time taken and number of reminders required for questionnaire return were used as indicators of practicality. RESULTS Participant nonresponse was significantly higher among participants who chose the postal questionnaire. The proportion of questionnaires with missing items and the mean number of missing items did not differ significantly by mode. A significantly larger proportion of tertiary-educated participants and managers/professionals completed the online questionnaire. There were no significant differences in age, relationship status, employment status, country of birth or language spoken by completion mode. Compared with postal questionnaires, online questionnaires were returned significantly more quickly and required significantly fewer reminders. CONCLUSIONS These results demonstrate that online questionnaire completion can be offered in a cancer sample without compromising data quality. In fact, data quality from online questionnaires may be superior due to lower rates of participant nonresponse. Investigators should be aware of potential sampling bias created by more highly educated participants and managers/professionals choosing to complete online questionnaires. Besides this issue, online questionnaires offer an efficient method for collecting high-quality data, with faster return and fewer reminders.
