Fig 1. The a priori model tested in the current study.

This is a path diagram describing the hypothesized effects of positive emotions and of the ability of the healthcare professionals to support patients’ autonomy on patient activation and medication adherence; it also describes the hypothesized mediating effect of patient engagement in this pathway. Unidirectional straight arrows indicate the predicted direction of the hypothesized effect. Note: HCCQ: Health Care Climate Questionnaire, PHE-s: Patient Health Engagement Scale, SAM: Self-Assessment Manikin Scale, PAM-13: Patient Activation Measure-short form, MMAS-4: 4 item-Morinsky Medication Adherence Scale.
