Measuring Quality of Life: A Case for Re-Examining the Assessment of Domain Importance Weighting

Domain importance weighting has long been a topic of debate in the study of quality of life (QoL). The purpose of this study is to examine the adequacy of popular approaches used to assess domain importance weighting with QoL measures that follow a formative-indicator approach. Using both empirical and simulation data, this study found that neither of the two popular methods of evaluating the performance of domain importance weighting in QoL measures, correlation and moderated regression analysis, was ideal in capturing the actual function domain importance weighting posited in the data. More specifically, results from the popular approaches used to assess domain importance weighting could be quite misleading when QoL measures were constructed using a formative-indicator approach. These findings call for a careful re-examination of results from previous studies using those popular approaches to assess domain importance weighting in QoL measures.     

Importance Weighting in the Domain-of-Life Approach to Subjective Well-Being: the Consideration of Age

The domain-of-life approach to subjective well-being (SWB) has been popular for decades. Recognizing the possibility that individuals may not perceive all life domains equally important, many researchers advocate for importance weighting, which is to incorporate the relative importance of life domains (i.e., domain importance) into the scoring of SWB at the individual level. However, the need for and the adequacy of importance weighting remain topics of debate. What has been missing in the debate is the consideration of influences of potential confounding factors. Given that age is significantly associated with domain satisfaction, domain importance, and SWB, assessing importance weighting should not ignore the potential confounding effect of age. Analyzing data from an online survey, we found that adjusting for the confounding effect of age produced negligible changes in the results of assessing the role that domain importance played in the relationship between domain satisfaction and SWB. Our findings support the observations from the literature that the results of assessing importance weighting depended on the SWB variable selected. However, given our non-probability study sample, future studies should continue to consider age as a confounder in assessing importance weighting in the domain-of-life approach to SWB.
