Modelling the Associations Between the Physician-Patient Relationship and Patient Outcomes via Self-Determination Theory Variables in Chronic Disease Management.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe aim of this study was to model the associations between the physician-patient relationship and patient outcomes, considering the mediating role of Self-Determination Theory variables.
methodThe current study comprised a sample (N = 226) of Australians with a diagnosed chronic health condition. Path analysis via structural equation modelling was used to model the relationships between patients' self-reported perception of the physician-patient relationship, motivation (autonomous and controlled), basic psychological needs (satisfaction and frustration), and patient outcomes (treatment adherence, mental health, and physical health).
resultsStronger physician-patient relationships indirectly predicted better physical and mental health, as well as greater adherence to treatment. This occurred through serial mediation, whereby stronger physician-patient relationships directly predicted need satisfaction, which in turn predicted autonomous motivation. Conversely, weaker physician-patient relationships indirectly predicted poorer mental health and lower adherence to treatment. This occurred through serial mediation where weaker physician-patient relationships predicted need frustration, which in turn predicted controlled motivation. Weaker physician-patient relationships also directly predicted controlled motivation.
conclusionSatisfaction of basic psychological needs plays an important role in predicting patient motivation and outcomes. The current findings provide evidence that the physician-patient relationship plays a direct role in facilitating satisfaction and frustration of psychological needs, as well as patient motivation. Attention should be placed on interventions aimed at improving the physician-patient relationship as a means through which to increase need satisfaction, autonomous motivation, and, consequently, patient adherence and outcomes.
