Estimation of a Multiattribute Utility Function for the Spanish Version of the TooL Questionnaire

Abstract

Utilities from the MAUF showed good psychometric properties, serving as a complement to generic health utilities. If misapplied, however, utilities from this instrument might favor the positive evaluation of drugs showing fewer associated side effects.

Chinese Time Trade-Off Values for EQ-5D Health States

“…Logically inconsistent values suggested that those participants failed to either understand or concentrate on the valuation questions. Therefore, as some of the previous health state valuation studies did [19,27], we excluded some of those participants who gave multiple logically inconsistent responses. It should be noted that many EQ-5D valuation studies did not exclude logically inconsistent values and that Lamers et al [28] found that inconsistent data did not have important effects on the modeling results when estimating the EQ-5D values.…”

Development of the Incontinence Utility Index: estimating population-based utilities associated with urinary problems from the Incontinence Quality of Life Questionnaire and Neurogenic Module

“…Regarding the elicitation process, methods applied are consistent with those used to develop one of the most widespread and robust generic utility measures, the HUI [ 10 , 11 ]. As has occurred in previous publications, the additive model was rejected in this study [ 10 , 11 , 42 ] and attributes were preference complements: for instance, the perceived limitation associated with being depressed and not having bladder control is greater than the separate effect of being depressed and not having bladder control, but smaller than the sum of these two problems.…”

“…Sample size was set to a minimum of 338 responders to enable the estimation of mean values with a confidence interval of ±0.032 points, and a standard deviation of 0.3 points, assuming a normal distribution of scores with a confidence interval of 95% (t-value = 1.96) [ 41 ]. However, given the complexity of the elicitation process and previous experiences [ 42 ], it was estimated that a maximum of 30% of the respondents would not be able to successfully complete all the proposed rating exercises. Hence, a total of 440 participants were interviewed.…”

“…A person-mean utility approach was used to estimate a general utility function based on community responses [ 10 , 11 , 42 ]. MAUF forms include the additive form, the multiplicative form and the multi-linear form [ 10 ].…”

Questionnaires for measuring fatigue and its impact on health perception in inflammatory bowel disease

“…The result is expressed as a tariff ranging from 0 to 1, considering 1 the best possible state and 0 the worst. The EuroQol-5D also includes a visual analog scale (VAS) for quality of life (37). The VAS consists of a 100 mm vertical line, like a thermometer, ranging from 0 (worst imaginable health state) to 100 (best imaginable health state).…”
