A Conceptual Framework for Understanding the Cultural and Contextual Factors on Autism Across the Globe

The growth of cross-cultural psychiatry is now occurring at a time when psychiatry in general is emphasizing diagnostic clarity and the use of quantifiable and reliable methods of collecting clinical and research data. It is now imperative that cross-cultural psychiatry also examine its methods for developing instruments for use in cross-cultural research. This paper outlines a method for developing instruments designed in one culture for use in a second, and particular attention is given to cross-cultural validity or equivalence. Five types of equivalence are enumerated and defined: content, semantic, technical, criterion, and conceptual equivalence. These concepts are illustrated by examples from the authors' experience in research on internal migrants in Peru.

Although concordance by race and sex in physician-patient relationships has been associated with patient ratings of better care, mechanisms through which concordance leads to better outcomes remains unknown. This investigation examined (1) whether patients' perceptions of similarity to their physicians predicted their ratings of quality of care and (2) whether perceived similarity was influenced by racial and sexual concordance and the physician's communication. The research design was a cross-sectional study with 214 patients and 29 primary care physicians from 10 private and public outpatient clinics. Measures included postvisit patient ratings of similarity to the physician; satisfaction, trust, and intent to adhere; and audiotape analysis of patient involvement and physicians' patient-centered communication. Factor analysis revealed 2 dimensions of similarity, personal (in beliefs, values) and ethnic (in race, community). Black and white patients in racially concordant interactions reported more personal and ethnic similarity (mean score, 87.6 and 78.8, respectively, on a 100-point scale) to their physicians than did minority patients (mean score, 81.4 and 41.2, respectively) and white patients (mean score, 84.4 and 41.9, respectively) in racially discordant encounters. In multivariable models, perceived personal similarity was predicted by the patient's age, education, and physicians' patient-centered communication, but not by racial or sexual concordance. Perceived personal similarity and physicians' patient-centered communication predicted patients' trust, satisfaction, and intent to adhere. The physician-patient relationship is strengthened when patients see themselves as similar to their physicians in personal beliefs, values, and communication. Perceived personal similarity is associated with higher ratings of trust, satisfaction, and intention to adhere. Race concordance is the primary predictor of perceived ethnic similarity, but several factors affect perceived personal similarity, including physicians' use of patient-centered communication.
