Abstract

In this chapter I review my working hypothesis and the available data that provide support. Central to this hypothesis is process of valuation. I discuss a number of aspects of the ­valuation process, first comparing statistical vs. cognitive approaches by examining the weighting task, then I discuss the cognitive basis of valuation methods, and finally discuss the literature demonstrating that values are stable parts of a person’s qualitative assessments. I also address what I consider to be the central issue in qualitative research: Can a quality be a quantity? This gave me the opportunity to consider the nature of measurement in the behavioral and social sciences, in general, and qualitative research, in particular. I briefly reviewed the history of development of subjective measurement and concluded that a greater role has to be found for axiomatic fundamental measurement in qualitative research. For this to happen, however, requires that investigators acknowledge the limitations of their current research strategy.

Notes

  1. 1.

    This quotation was included in an article by Michell (1997). I have left a portion of the quote out that is available in the article.

  2. 2.

    By “thinking about” I mean both conscious and unconscious cognitive processes.

  3. 3.

    Kahneman’s approach has limited generality since it rejects a role for retrospective assessments in a qualitative assessment, yet it is clear that reflection is a regular part of a qualitative assessment, while Rasch’s approach is limited to the verbally fluent and breaks down when applied to the compromised person.

  4. 4.

    The summary qualitative statements were calculated by combining weights using either or both additive or multiplicative methods.

  5. 5.

    There are, however, alternative methods that could have been used by the authors of the QLI that would have a greater chance of evoking the reflective process hypothesized as being a critical part of a qualitative assessment. For example, the respondent might be asked to reread their satisfaction rating so that when they made their importance rating it was in the context of an estimate of their satisfaction. This ploy might generate the more delayed thought process characteristic of reflection. It would be even possible to measure the reaction time to the importance question with or without review of the satisfaction question, and in this way, provide some evidence that a reflective process occurred.

  6. 6.

    QLI is not unique in this regard, since I believe many qualitative assessments generate a summary statement using metaphoric arithmetization. This implies that the only “valid” measure of quality is a global assessment produced by the respondent.

  7. 7.

    An example of a study that avoids some of the difficulties that Ferrans and Powers have with their study but which still engages in metaphoric arithmetization is the Laman and Lankhorst (1994) report. In this study, respondents were administered the evaluated descriptor and importance weighting task concurrently, and the summary score involved multiplying these indicators and adding them together. Thus, this study avoids the potential confounding of sequential assessments, but the summary of this assessment still is subject to concerns about the meaning generated.

  8. 8.

    It is of interest to note that the Breast Cancer Questionnaire (Levine et al. 1988) did not include weights when the assessments were summed to give a composite score.

  9. 9.

    The term happiness, more so than satisfaction, is likely to evoke an experienced emotion, although it is possible that comparisons are also made when happiness is reported (e.g., as when using attaching the word “happiness” to a feeling that was evaluated). In addition, satisfaction is traditionally thought of as a representative of a “cognitive” process in attitude research.

  10. 10.

    This statement is additional evidence for the presence of metaphoric arithmetization.

  11. 11.

    It would be interesting to know more about the characteristics of these persons. For example, were they healthier than the persons who indicated clearer domain preferences? If so, then this would be consistent with the data from subjects that were presumed to be “healthy” (see Table 12:2; Part A).

  12. 12.

    The standard deviations from Table 1 (Hagell and Westergren 2006) were actually uniformly lower than what was found for total QLI score and its four subdomains.

  13. 13.

    The kind of experiment that I think should be done would involve asking a person to rate their satisfaction of a particular domain, say along a 7 point Likert scale, and then having identified this rating, immediately ask the person to rate the importance of this particular satisfaction rating. I would also include a control group where the two assessments were done consecutively. There are several analyses that could be done. First, does presenting the satisfaction rating immediately followed by the importance rating increase the importance rating compared to rating the domain independently, and second whether multiplying the importance rating by the satisfaction ratings statistically significantly increases the domain score. Aggregating these domains into a global assessment might be more complex because some domain composite scores may go up or some may go down after weighting, so that demonstrating that the weighted satisfactions scores accounts for more variance may not be straightforward and would require detailed subgroup analyses.

  14. 14.

    As will become clear in this section, this is exactly what happens when such standard qualitative assessments as the HUI or the QWB are used. In both cases, what is summed is the value, or utilities, not the ratings of the evaluated descriptors.

  15. 15.

    Before I proceed I need to review and clarify the difference between a number of terms that I have been using. I have already clarified the difference between the phrase “evaluated descriptor” and “valuation” (Chap. 8, p. 270), discussed the contribution of evaluated descriptor to inductive theory building, how qualitative researchers are prone to deductive imposition (Spates 1983; p. 42) or metaphoric arithmetization, and how evaluation of descriptors involves a conscious act, while valuation is a continuous mostly unconscious process. Now I would like to differentiate the terms value and appraisal, since they appear to semantically and cognitively overlap. A value, as a noun, refers to an idealized outcome or state, as such it is a abstract cognitive entity whose meaning is clarified by its concrete examples. In contrast, the term appraisal, as a noun, refers to the fact that a process has occurred (e.g., an evaluation) involving an object or life lived, and therefore, would be cognitively represented as a more concrete entity. Both valuation and appraisal may involve an evaluation, but valuation as a metacognitive process (Chap. 3, p. 64) may occur either as a nonconscious or continuous process. Thus, the terms appraisal and valuation overlap, but are sufficiently distinct that they should not be used as synonyms.

  16. 16.

    The investigators who developed these methods may not acknowledge that their procedures reflected how a person thinks, but to the extent that a person can complete the tasks involved (e.g., using the VAS, TTO, or SG), then it is certainly reasonable to assume that a person is capable of thinking in these ways, and that some may actually think this way when making decisions or judgments.

  17. 17.

    Fryback’s concern have a long history starting with a study by Patrick et al. (1973).

  18. 18.

    What I call “evaluated descriptors” Torrance et al. (1995) describes as a classification system, while what I describe as “valuation” they describe as preferences. The classification system consists of a variety of domains, and selection of levels within a domain results in a profile that characterizes the individual respondent. A preference implies that a choice has occurred, but a valuation refers to both a current and past process. Either can occur under conditions of ­certainty or uncertainty. Thus, the term valuation is a more comprehensive and inclusive term.

  19. 19.

    Bell et al. (1988) use their models to refer to decisions and choices under conditions of uncertainty, but I feel it can also be applied to decisions and choices where the outcomes are certain, such as a rating.

  20. 20.

    The TTO assumes that the utility of life duration is linear, so that it would be imperative that any correction supports this assumption.

  21. 21.

    An example of this type of study would be Sen’s (2001) report that residents of more affluent areas of India have more expectations (and therefore loss aversion) than other poorer areas and as a result expect and receive better healthcare services.
