Job satisfaction and opinion surveys ask respondents to provide ratings on a set of items. One response scale might be a five point rating scale measuring satisfaction (e.g., 5-point strongly dissatisfied to strongly satisfied) with the item content (e.g., "Opportunities for promotion"). Some tests also gather for each item "importance" ratings.

  • What are the psychometric properties of importance versus satisfaction scales?
  • To what extent is the incremental information provided by importance ratings justified?

1 Answer 1


Computing overall satisfaction

There is discussion in the literature about whether measures of overall satisfaction should be calculated as some form of weighted composite of facet satisfaction where weights are derived from importance ratings. These debates have been applied to various types of satisfaction including life, job, and customer. In this context, it does not seem like weighting by importance makes much difference, and it may even be detrimental.

For examples, Trauer et al (2001) state that:

Many Quality of Life (QoL) instruments ask respondents to rate a number of life domains in terms of satisfaction and personal importance, and derive weighted satisfaction scores by multiplying the two rat- ings. This paper demonstrates that this practice is both undesirable and unnecessary. QoL domains are selected on the basis of their inherent importance, rendering separate importance rating partially redun- dant. Weighted scores present difficulties in interpretation. Further, we show that multiplicative composites have undesirable psychometric properties. There is evidence that multiplicative composites have little or no advantage over unweighted ratings in correlational or predictive studies. Apart from the face validity and the intuitive appeal of multiplying satisfaction ratings by importance ratings, there appear to be no sound reasons for doing so, and several good reasons not to do so.

A similar critique of importance ratings in the job satisfaction domain can be seen in Blood (1971).

Nonetheless, this all assumes that importance measurement is a means for forming an overall composite. In some instances, measurement of importance is of substantive interest. Trauer et al (2001) acknowledge this when they write:

It is not suggested that the assessment of the importance of domains of satisfaction is inconsequential. It has been shown that domains that are closer to the personal core (e.g. health, marriage, family) are typically judged as more im- portant than more peripheral domains (e.g. membership of organizations)...

Study of mean importance ratings

Importance ratings can be used to assess average perceptions of importance which might inform causal hypotheses regarding what is influencing satisfaction.

Take for example, Rice et al (1991) among many other things, they report importance ratings of various job facets. Among other things the authors asked 97 employed college students to rate

facet importance on a 9-point scale with two verbal anchors: not at all important and extremely important (e.g., "How important to you is the amount of opportunity for promotion?").

If we sort the results reported in Table 1 by importance we see the following:

Job Facet                     Mean Importance
Hourly pay (dollars)              7.4
Hours per week                    7.3
Control over schedule             7.3
Opportunity to learn skills       6.7
Decision making                   6.4
Promotion opportunity             6.3
Mental effort required            6.1
Conversation with co-workers      6.0
Customer or client contact        5.7
Physical effort required          5.4
Supervisor contact                5.3
Commuting time (minutes)          4.3

This is presumably an interesting empirical finding in itself.

Relationship between importance and satisfaction

Some researchers have explicitly studied the relationship between importance and satisfaction to see whether there is a relationship. E.g., Borg (1991) provides an example of job satisfaction exploring how intra-individual variability in facet job satisfaction relates to facet importance. They find support both for the idea that more important facets are deemed more satisfying and for a u-shaped relationship where it is the most and least satisfied facets that are the most important. This variation depends on the domain being studied.
