- Provider cultural competency is often identified as an important component of effective ethnic minority healthcare. However, there is limited knowledge of the manner in which cultural competency judgments operate. This study sought to provide an initial demonstration of a hitherto overlooked methodology for examining the extent to which provider cultural competency ratings reflect characteristics of providers, differences among perceivers, and also idiosyncratic pairings of specific perceivers and providers. Second and third year medical residents rated four attending physicians for cultural competency when treating African-American patients. Using a Generalizability Theory approach, cultural competency ratings were shown to most substantially reflect unique perceiver and provider pairings (47.0% relationship effect). However, cultural competency also strongly reflected differences among resident raters in their tendency to perceive attending physicians as culturally competent, regardless of the characteristics of physicians (35.0% perceiver effect). Although cultural competency significantly reflected the characteristics of providers this effect was small (3.0% provider effect). This study demonstrates an overlooked methodological approach and suggests important new directions for conceptualizing theory and research.

- Perceived preventability of illness is an important predictor of health behaviour and response to illness. Yet, health experts remain largely unaware of the extent to which preventability attributions reflect characteristics of persons, illnesses and their interaction. Quantifying the sources of variance that compose illness preventability attributions may be especially useful for designing effective preventative health interventions. In the present study, we used generalisability theory to examine the sources of variance in illness preventability attributions. Undergraduate college students (N = 44) rated the personal preventability of 12 well-known physical illnesses. Preventability attributions were shown to most substantially reflect characteristics of illnesses (57.5% target effect). However, preventability attributions also strongly reflected interactions of individuals and illnesses (26.0% relationship effect). Characteristics of individuals were also significant, although they explained a relatively smaller amount of variance (7.1% perceiver effect). In general, these results suggest new directions for conceptualising theory and research on perceived preventability of illness.
