“…The CVI process and item refinement were repeated until an acceptable level of content validity was reached (average CVI ≥ 0.80; [ 48 ]). Items were ordered thematically in relation to the domain they were intended to represent, as this has been shown to enhance internal consistency reliability ( 49 , 50 ).…”

Fully automated vehicles hold promise for providing numerous societal benefits, including drastically reducing road fatalities. However, we know little about the adoption practices of individuals related to automated vehicles. To assess transportation users’ perceptions of automated vehicles, a 40-item survey was designed using guidance from several technology acceptance models. A focus group was used to assess face validity to ensure the items appeared credible and understandable to the layperson. Seven subject-matter experts rated items for their relevance to provide a content validity index for each item and for the overall survey. The final scale had a scale content validity index rating of 1.00, with 32 of 32 items rated greater than or equal to 0.86 and a scale content validity index of 0.96 (mean content validity index of all items), indicating acceptable content validity. The approach adopted in this study ensured the face and content validity of the survey and enhanced the items’ relevance, concision, and clarity. Future validation is required to assess scale reliability and validity. The paper provides an overview of models used for determining acceptance and adoption of technology and describes in detail the methodology used to establish face and content validity of the questionnaire survey developed for assessing adults’ perceptions of automated vehicles.

“…The survey consisted of three 5-point Likert-scale questions and four open-ended questions. For the Likert-scale questions the "I don't know" option was also available, in order to provide the participants with a non-forced choice to respond if they did not wish to offer a specific opinion [21].…”

Thermal imaging of the fetus: An empirical feasibility study

2020

Digital Infrared Thermal Imaging (DITI) has much potential in the field of maternal-fetal health and wellbeing research. The fact that it is totally non-invasive is particularly important in this context. The purpose of this study was, for the first time, to assess DITI's ability to record fetal presentation and position, and other pregnancy-related physiological factors, via their superficial thermal prints. Ten healthy pregnant women (approximately 34-37 weeks of gestation) were recorded with two thermal imaging cameras (Flir C3 and i3 TE-Q1) from five different viewpoints. Participants' views about the use of DITI in research and clinical practice were also assessed by a completion of a survey. Free hand polygon region of interests (ROIs) were drawn in order to include the entire anatomical area for investigation. The use of free hand polygon ROIs showed high reliability. Thermal images analysis revealed that fetuses presenting cephalically can be identified by the use of DITI, under specific conditions. Fetal movements influenced the thermal patterns that were produced. Future studies need to verify the heat patterns on the skin related to the placenta location, in order to understand the produced thermal recordings. Pregnant women rated the idea of using DITI in research and clinical practice very highly. This work represents a first contribution towards the use of DITI for the recording of fetal presentation and position. As it does not require direct contact and since it is completely non-invasive, it could be used to record maternal-fetal dynamic dyadic interaction in pregnancy. However, although the preliminary results are promising, further trans-disciplinary studies with a well-established protocol, more sophisticated thermal cameras, and bigger cohorts are needed.

“…First, some people may provide a nonopinion when they actually have one, leading to what Gilljam and Granberg (1993) term ''false negatives,'' and the tendency to do this may be affected by the visual prominence of the category. Lam et al (2002) found that the placement of the ''don't know'' response option in a list had little effect on its use; however, Stern et al (2007) found just the opposite. Second, although it has not yet been 20.…”

The Effects of Item Saliency and Question Design on Measurement Error in a Self-Administered Survey

2012

Recent survey design research has shown that small changes in the structure and visual layout of questions can affect respondents' answers, but the results are not always consistent across studies. One possible reason for some of the inconsistency may be differences in the item saliency of the questions used in the experiments. In this article, the authors examine how item saliency might influence visual design effects. The authors report the results of three experimental alterations in question format and visual design using data from a 2005 random sample mail survey of 1,315 households. The results suggest that the saliency of the questions has effects both independent of and in concert with the layout of the questions. The implications for survey design are discussed.
