“…The EuroQol Group operates a rigorous translation process according to a standard protocol that conforms to internationally recognised guidelines. The guidelines aim to ensure equivalence to the English source version and involve a forward/backward translation process and cognitive debriefing [12, 13]. Nevertheless, it is inevitable that there will be some elements of inconsistency across translations.…”

One-to-one versus group setting for conducting computer-assisted TTO studies: findings from pilot studies in England and the Netherlands

We compare two settings for administering time trade-off (TTO) tasks in computer-assisted interviews (one-to-one, interviewer-led versus group, self-complete) by examining the quality of the data generated in pilot studies undertaken in England and the Netherlands. The two studies used near-identical methods, except that in England, data were collected in one-to-one interviews with substantial amounts of interviewer assistance, whereas in the Netherlands, the computer aid was used as a self-completion tool in group interviews with lesser amounts of interviewer assistance. In total, 801 members of the general public (403 in England; 398 in the Netherlands) each completed five TTO valuations of EQ-5D-5L health states. Respondents in the Netherlands study showed a greater tendency to give ‘round number’ values such as 0 and 1 and to complete tasks using a minimal number of iterative steps. They also showed a greater tendency to skip the animated instructions that preceded the first task and to take into account assumptions that they were specifically asked not to take into account. When faced with a pair of health states in which one state dominated the other, respondents in the Netherlands study were more likely than those in the England study to give a higher value to the dominant health state. On the basis of these comparisons, we conclude that the one-to-one, interviewer-led setting is superior to the group, self-complete setting in terms of the quality of data generated and that the former is more suitable than the latter for TTO studies being used to value EQ-5D-5L.

“…The EQ‐5D comprises five questions on mobility, self‐care, pain, usual activities, and psychological status with three possible answers for each item (1 = no problems, 2 = moderate problems, 3 = severe problems) 23 .

The Impact of Dyspepsia on Symptom Severity and Quality of Life in Adults with Headache

et al. 2015

BackgroundDyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache.MethodsA cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone.Results280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0±17.3 years, 57.0% females and ethnic distribution—Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39–5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67±22.85 mm vs 51.20 ±24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82±0.18 vs 0.90 ±0.16, p = 0.037 and EQ-5D VAS 62.08±17.50 mm vs 72.62 ±18.85 mm, p = 0.018), compared to those without dyspepsia.ConclusionDyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache.
