- Abstract
Surveys are an important research modality in ophthalmology, but their quality has not been rigorously assessed. This study evaluated the quality of published ophthalmic surveys. Three survey methodologists, three senior ophthalmologists, and two research assistants developed a survey evaluation instrument focused on survey development and testing; sampling frame; response bias; results reporting; and ethics. Two investigators used the instrument to assess the quality of all ophthalmic surveys that were published between January 1, 2018 and December 31, 2018; indexed in MEDLINE/PubMed, Embase, and/or Web of Science; contained the search terms “ophthalmology” and “survey” or “questionnaire” in the title and/or abstract; and were available in English. The search identified 626 articles; 60 met the eligibility criteria and were assessed with the survey evaluation instrument. Most surveys (93%; 56/60) defined the study population; 48% (29/60) described how question items were chosen; 30% (18/60) provided the survey for review or described the questions in sufficient detail; 30% (18/60) were pre-tested or piloted; 25% (15/60) reported validity/clinical sensibility testing; 15% (9/60) described techniques used to assess non-response bias; and 63% (38/60) documented review by an institutional review board (IRB). The quality of published ophthalmic surveys can be improved by focusing on survey development, pilot testing, non-response bias and institutional review board review. The survey evaluation instrument can help guide researchers in conducting quality ophthalmic surveys and assist journal editors in evaluating surveys submitted for publication.

Physician surveys are now commonly conducted online, although there is little information currently available regarding the practice of online survey research with health care professionals. We addressed this concern by conducting an overview and assessment of the methodologies disclosed in a sample of 200 published papers that report findings from web-based surveys of physicians. Fifteen methodological aspects of web surveys were coded from each paper, and a transparency index based on aggregation of these various indicators was constructed to evaluate overall survey quality. Some indicators, such as the source and type of samples, along with information regarding ethical aspects of protocols, were commonly reported. In contrast, the use of incentives, and discussion of potential coverage and processing errors were reported less frequently. We hypothesize that these reporting patterns may be dictated by journal requirements. As web surveys are destined to serve as an important modality for data collection from physicians and other health care professionals for the foreseeable future, it is important to encourage – if not require – researchers to regularly disclose a broader range of quality indicators when reporting their research findings.

In an optimal design for mixed‐mode surveys, be it within a country or across countries, there are three phases that need attention. The first phase is the design phase: it is important to prevent mode measurement effects when designing the study. A richer source of additional data will help to achieve a better estimation of mode effects. After the data are collected, the next two phases are estimating the potential mode measurement effect due to different modes and adjusting for any such bias. Survey modes differ on several dimensions, for instance, interviewer‐administered versus self‐administered questionnaires and information transmission and communication. The use of well‐established and validated constructs and multiquestion scales across countries and modes helps achieving measurement equivalence countries and modes. Mixed‐mode designs and mode changes are often implemented for sound methodological reasons. Using a mixed‐mode design implies a careful trade‐off among coverage, nonresponse, measurement errors, and cost.

This chapter focuses on a practical analysis of the Bayesian approximate measurement invariance model using standard software. It introduces the concept of approximate measurement invariance and illustrates the use of its most basic variant. The chapter discusses the use of measurement invariance testing in latent variable measurement models. In such models, the response functions are estimated through presumed conditional independence assumptions, and investigation of measurement invariance proceeds through restrictions on the parameters of these estimated functions. The most common model for this test is the confirmatory factor model, but this framework also includes item response theory (IRT) models, latent class models, and generalized multitrait‐multimethod models. The chapter focuses on a multigroup confirmatory factor analysis (MGCFA). The methodological literature on cross‐cultural and cross‐country analysis has recommended testing for measurement equivalence to guarantee that differences across groups are due to substantive true differences and not methodological artifacts

Um Charakteristika gleicher Fragen in Gesundheitsumfragen im Zusammenhang mit interkulturellen Unterschieden im Verständnis dieser Fragen zu identifizieren, analysieren die Verfasser Befragungen zum Gesundheitssystem, wobei die Befragten vier verschiedene kulturelle Subgruppen in den USA repräsentieren (weiße Nicht-Hispanics, Afroamerikaner, mexikanische Amerikaner und Puerto Ricaner) mit Hilfe des Instruments des Behaviour Coding. Untersucht werden die Auswirkungen von vier Merkmalen der Fragebogenkonstruktion auf kulturelle Schwierigkeiten beim Verständnis der Fragen. Die empirische Datenbasis bilden 13514 Antworten von 345 Befragten auf 42 Fragen. Es zeigt sich, dass das Antwortformat, die Länge der Frage sowie das Lese- und Abstraktionsniveau der Fragen einen wesentlichen Einfluss auf das Verständnis der Fragen bei den Befragten haben. Die Kultur der Befragen hatte einen moderierenden Einfluss auf die Effekte von Antwortformat, Fragenlänge und Leseniveau. Verschiedene Aspekte des Fragebogendesigns, die den Fragebogen allgemein verständlicher machen sollen, haben ebenfalls kulturspezifische Auswirkungen. (ICEÜbers)

"In cross-cultural (and cross-national) survey research, the equivalence of survey questions rivals the importance of their reliability and validity. This paper presents a review of the multiple dimensions of equivalence that must be addressed when conducting comparative survey research. Available methodologies for establishing one or more forms of equivalence are also identified and the strengths and limitations of each approach are examined. It is concluded that multiple methodologies must be implemented in order to insure the cross-cultural equivalence of survey measures." (author's abstract)
