RODRIGUEZ-MIGUEZ, Eva  y  MOSQUERA NOGUEIRA, Jacinto. Measuring the impact of alcohol-related disorders on quality of life through general population preferences. Gac Sanit [online]. 2017, vol.31, n.2, pp.89-94. ISSN 0213-9111.  http://dx.doi.org/10.1016/j.gaceta.2016.07.011.

Objective:

To estimate the intangible effects of alcohol misuse on the drinker's quality of life, based on general population preferences.

Methods:

The most important effects (dimensions) were identified by means of two focus groups conducted with patients and specialists. The levels of these dimensions were combined to yield different scenarios. A sample of 300 people taken from the general Spanish population evaluated a subset of these scenarios, selected by using a fractional factorial design. We used the probability lottery equivalent method to derive the utility score for the evaluated scenarios, and the random-effects regression model to estimate the relative importance of each dimension and to derive the utility score for the rest of scenarios not directly evaluated.

Results:

Four main dimensions were identified (family, physical health, psychological health and social) and divided into three levels of intensity. We found a wide variation in the utilities associated with the scenarios directly evaluated (ranging from 0.09 to 0.78). The dimensions with the greatest relative importance were physical health (36.4%) and family consequences (31.3%), followed by psychological (20.5%) and social consequences (11.8%).

Conclusions:

Our findings confirm the benefits of adopting a heterogeneous approach to measure the effects of alcohol misuse. The estimated utilities could have both clinical and economic applications.
