Effects of physical and mental health on health-state preferences.

Studies concerned with measuring values and preferences for health states and health status components have typically employed "direct" scaling techniques that require conclusions to be based on definition. Problems and limitations of direct scaling are discussed. The algebraic modeling approach is new to health services research; it emphasizes testing models of how respondents combine stimulus information. The model specifies the causal relationship between the stimulus information and the responses. Subjective stimulus and response scales are derived from the model when the data satisfy the model's predictions. Thus, the validity of the subjective scale values rests on the validity of the model. In the present research, university students judged preferences between health states, each described by a physical (degree of physical activity) and mental (level of happiness/depression) component. The object of the research was to determine the subjective trade-offs between physical and mental health values in these preference judgments. For all respondents, preference judgments were consistent with the predictions of a preference model that yielded interval scales of the health states. Also, there were systematic interactions between physical and mental values, so that when a health state was bad on one component (e.g., poor physical health), the other component had less of an effect. However, results revealed individual differences in emphasis placed on the physical and mental health components. Advantages of replacing presently used measurement techniques with the algebraic modeling approach in general population studies are discussed.

Comment on internal feedback as a theory of judgment: a reply to Levin.

Levin's suggestion that internal feedback strategies be employed in judgmental and learning tasks is discussed. The predictions of an internal feedback notion are seen as inconsistent with Veit's ratio and difference task data. Scale-free frameworks and scale-convergence criteria used in previous research are described as useful techniques for separating integration from judgmental processes in information-integration as well as learning-task situations.

Motivating mammography adherence in elderly Latinas: a test of three mathematical models of decision making.

Many elderly Latinas do not have mammography every one to two years as recommended by cancer organizations. To elucidate the causal factors underlying this behavior, 52 Latinas, aged 65 and over, were asked to judge the likelihood of having yearly mammography in 79 different scenarios constructed from factor levels of cost, perceived risk, and the source of a recommendation (none, a recognized cancer organization, a doctor), assuming a convenient mammography facility. A configural-weight-averaging model, with different parameter values for the 30 adherers (women who reported having had mammography at least twice in the preceding four years) and the 22 non-adherers, gave a good fit to the data and did well in predicting reported mammography adherence (r = 0.85). According to this model, offering free mammography would not induce non-adherers to adhere; they would require a recommendation, and value a doctor's as highly as that of a recognized cancer organization, but reported never having received one from either source. All 52 women reported never receiving risk information from any source. These results have direct educational and dissemination implications for cancer organizations.
