The Associations Between Physician-Patient Communication and Adjustment Outcomes of Patients and Physicians: A Systematic Review and Meta-Analysis of Correlations.

Physician-Patient communication (PPC) has been linked to patient adjustment outcomes. However, conflicting results have been reported and previous systematic reviews showed some methodological weaknesses. It has also been suggested that PPC is related to physicians' own adjustment outcomes. This systematic review aims to explore and synthesize the associations between PPC and both patient and physician adjustment outcomes. A systematic search was conducted primarily in five databases and 11.488 non-duplicated articles were identified. Forty-five studies met the eligibility criteria and data extraction was performed for sample characteristics, PPC measurement, adjustment outcomes under examination and main outcomes. The observed results showed that the majority of the included studies were cross-sectional, assessed PPC by proxy-report and reported an overall positive association with patients' adjustment outcomes. None of the studies examined the association between PPC and physicians' adjustment outcomes. Thirty-three studies were meta-analyzed and showed a positive and significant association between PPC and patients' adjustment outcomes (r = .16). Due to the small number of studies included in the meta-analysis, the heterogeneity was high. Subgroup analysis could not identify sources for heterogeneity. Research on the associations between PPC and physicians' own adjustment outcomes is warranted. Future studies should be rigorous in defining clear PPC definitions, directionality of communication processes, and study design.
