Using Plain Language and Adding Communication Technology to an Existing Health-Related Questionnaire to Help Generate Accurate Information: Qualitative Study

Abstract

BackgroundLow-educated patients are disadvantaged in using questionnaires within the health care setting because most health-related questionnaires do not take the educational background of patients into account. The Dutch Talking Touch Screen Questionnaire (DTTSQ) was developed in an attempt to meet the needs of low-educated patients by using plain language and adding communication technology to an existing paper-based questionnaire. For physical therapists to use the DTTSQ as part of their intake procedure, it needs to generate accurate information from all of their patients, independent of educational level.ObjectiveThe aim of this study was to get a first impression of the information that is generated by the DTTSQ. To achieve this goal, response processes of physical therapy patients with diverse levels of education were analyzed.MethodsThe qualitative Three-Step Test-Interview method was used to collect observational data on actual response behavior of 24 physical therapy patients with diverse levels of education. The interviews included both think-aloud and retrospective probing techniques.ResultsOf the 24 respondents, 20 encountered one or more problems during their response process. The use of plain language and information and communication technology (ICT) appeared to have a positive effect on the comprehensibility of the DTTSQ. However, it also had some negative effects on the interpretation, retrieval, judgment, and response selection within the response processes of the participants in this study. No educational group in this research population stood out from the rest in the kind or number of problems that arose. All respondents recognized themselves in the outcomes of the questionnaire.ConclusionsThe use of plain language and ICT within the DTTSQ had both positive and negative effects on the response processes of its target population. The results of this study emphasize the importance of earlier recommendations to accompany any adaption of any questionnaire to a new mode of delivery by demonstrating the difference and equivalence between the two different modes and to scientifically evaluate the applicability of the newly developed mode of the questionnaire in its intended setting. This is especially important in a digital era in which the use of plain language within health care is increasingly being advocated.

The effect of psychological resilience on functional outcomes in post-operative hip fracture patients in a Singapore community hospital

“…49 Health literacy is key in producing accurate information about a patient's knowledge, attitudes and perceptions, but less educated patients face struggles filling out medical questionnaires. 50 This limitation was partially circumvented by using standardised interviewer administered language questionnaires in English, Mandarin, Malay or Tamil, but many were excluded due to their inability to understand the questionnaires.…”

A Mobile Patient-Reported Outcome Measure App With Talking Touchscreen: Usability Assessment

“…During further development of the DTTSQ, both the results of this study and the study on response process of the DTTSQ [36] should be taken into account simultaneously. The usability and the response processes will have to be retested in exactly the same manner after adjustments in the DTTSQ have been made.…”

“…Data were collected in the same study population and at the same time as the data reported in a paper earlier published by Welbie et al [36]. Recruitment took place in 11 primary care practices in deprived areas of Utrecht, The Netherlands.…”

“…Throughout the recruitment process, the recruiting physical therapists were constantly kept informed about the profiles of participants the researchers were looking for. In total, 24 physical therapy patients were included in this study [36]. Characteristics of the study population can be found in Tables 1 and 2.…”

Resident Preferences for Urban Green Spaces in Response to Pandemic Public Health Emergency: A Case Study of Shanghai

“…Before its official launch, the questionnaire underwent three rounds of optimization following pre-testing with 50 samples [47]. The questions in the questionnaire are concise and easy to understand, which facilitates successful responses from both lay and less educated groups [48]. Throughout this process, the feedback of Shanghai residents was thoroughly considered to refine the questionnaire, ensuring its questions closely mirrored real-life circumstances and were easily comprehensible [49].…”
