“…A different market research company was hired to conduct the face-to-face interviews; nevertheless, because of the coronavirus disease 2019 (COVID-19) pandemic, 77 interviews were conducted remotely using video conference facilities. Our interviewers had previous experience conducting C-TTO interviews, 4,19 but they also received a 1-day training course for this specific study. Initial participants were invited to a central location for being interviewed in a face-to-face setting.…”

Objectives: The EuroQol Group published the EQ-5D-Y valuation protocol that recommends 2 valuation techniques to elicit preferences: composite time trade-off (C-TTO) and discrete choice experiments (DCEs). The protocol left the decision of what modeling approach to use open for researchers. Our aims were to explore modeling strategies allowing generation of EQ-5D-Y value sets and to produce an EQ-5D-Y Spanish value set. Methods:We used EQ-5D-Y DCE and C-TTO data collected in Spain following the protocol and adopted a staged approach for our modeling exercise. First, we selected the best performing DCE latent class model and evaluated models from 2 to 10 classes. We selected the preferred model based on best goodness of fit in terms of the Bayesian information criterion. We considered 2 anchoring approaches to estimate utility values: (1) pits state anchoring and (2) hybrid models (using all available C-TTO responses). All analysis were weighted to be representative of the Spanish population.Results: We collected 1005 DCE and 200 C-TTO interviews. We selected a DCE model including 4 classes. Hybrid models using all available C-TTO observations produced a narrower range of values than the pits state anchoring approach.Conclusions: In this article, we have presented an EQ-5D-Y value set that can be used for cost-utility analysis in Spain. The international EQ-5D-Y valuation protocol should be updated to include a different set of health states for the C-TTO experiment if researchers wish to use alternative anchoring approaches to the "pits state."Keywords: composite time trade-off, discrete choice experiment, EQ-5D-Y, health-related quality of life, value set.

“…The derived insights can be used to develop thorough and specific guidelines to train, monitor and provide feedback to the interviewers (Sebastian et al, 2012). However, most studies tend to simply highlight that measures have been taken to control for potential interviewer effects (e.g., Marsden & Hollstein, 2022; Ramos-Goñi et al, 2016). For those studies that documented the presence of misbehaviours, they tend to focus on one or two of them (e.g., Dykema, 2005; Olbrich et al, 2022).…”

While survey research has expanded rapidly in recent times, little scholarly work has examined interviewer misbehaviour. Inspired by audit principles, this paper aims to identify themes of misbehaviours associated with interviewing. Using thematic analysis, it provides exploratory insights into misbehaviours vis-à-vis audit reports prepared by auditors through their observations of interviewers administering face-to-face surveys. 398 audit reports were reviewed and scrutinised for depictions of misbehaviour, and a total of eight themes were derived. These themes were then aggregated into three domains: issues with asking questions (78%), issues with probing answers (16%), and issues with conduct (5%). Analysis of the themes reveals behavioural patterns that point to actionable areas that researchers and market research agencies can adopt to curb misbehaviour. The findings are also discussed with respect to the utilisation of the audit perspective in deepening our understanding of interviewers and their behaviours.

Does the Introduction of the Ranking Task in Valuation Studies Improve Data Quality and Reduce Inconsistencies? The Case of the EQ-5D-5L

Abstract: The benefit does not justify the effort involved in the ranking task. For this reason, the addition of the ranking task to the present EQ-5D-5L valuation protocol is not an attractive option.
