Challenging a Fundamental Proposition of Patient-Centeredness.

This investigation challenged the proposition that physician patient-centeredness influences patients' experience-of-care (PEC). A theory-driven, three-factor, multigroup structural equation modeling design, using asymptotic-distribution-free and bootstrap estimation, with two national random and 5,000 bootstrap samples challenged the proposition's plausibility, measurement invariance, replicability, robustness against a competing model, and coherence with theory. The model fit [χ²(39) = 28, p =.900, RMSEA = .001, p = 1.00, CFI = 1.00], explaining 81 percent of PEC's variance; the proposition was invariant across samples, held against the competing model [χ²Δ(7) = 7.82, p = .97]; cross-validated against estimates from the 5,000 bootstrap samples; and agreed with theory. One standardized increase in patient-centeredness increased PEC, likelihood of recommending, and care ratings by .807, .765, and .771. Results converged in sustaining the plausibility of the proposition.
