The Effect of Shared Decision-Making by Mental Health Nurses on Medication Adherence in Patients with Alcohol Use Disorders: Provider-Patient Communication Pathway Model.

The involvement of patients with mental health issues in their own treatment decision-making has often been overlooked. This study aimed to investigate the impact of shared decision-making between mental health nurses and patients with alcohol use disorders (AUD) on medication adherence. The provider-patient communication pathway model was utilized to examine the ways in which therapeutic communication strategies employed by mental health nurses positively influence medication adherence. The study employed a percentile bootstrap method and pairwise comparison tests in structural equation modeling. The results revealed that shared decision-making between AUD patients and mental health nurses directly enhanced medication adherence, as well as indirectly influenced adherence through the mediating factors of therapeutic alliance and alcohol abstinence self-efficacy. These findings hold both theoretical and practical implications for involving patients with AUD in therapeutic decision-making within psychiatric and mental health nursing settings, as well as for improving medication adherence among this patient population.
