The physician-patient relationship is important and essential to the delivery of effective healthcare. The current study examined a measure of this relationship, which we call the physician-patient working alliance (PPWA). We examined it from both perspectives of the medical dyad, simultaneously, which to date has not been done. Data were analyzed via the Actor Partner Interdependence Model to account for the possibility of interdependence in the ratings provided by each member of the dyad. The sample consisted of sixty-eight physician-patient dyads. Patients' ratings of the PPWA were significantly associated with their ratings of adherence to, and satisfaction with treatment. Physicians' ratings of the PPWA were significantly associated with their ratings of patient adherence and to their own satisfaction with treatment. Significant "partner" effects were uncovered, in that physicians' ratings of the PPWA were significantly associated with patients' ratings of adherence. Significant zero-order correlations were also observed for physician-rated outcome; particularly, significant correlations with patient-rated and physician-rated adherence. We conclude that the PPWA is a significant factor in patients' and physicians' ratings of adherence and satisfaction. This study also provides initial evidence that the PPWA is a dyadic phenomenon (e.g., the perception of the strength of the PPWA in one member of the medical dyad impacts the other member's perception) and that both parts of the medical dyad should be considered in future research and in clinical practice.
