Correlates of Control Preferences, Participation in Decision-making and Activation in Patients with Substance Use Disorder.

BACKGROUND: Treatment of Substance Use Disorder (SUD) is complex and therefore including patients in the therapeutic process is needed. Patient-Centered Care (PCC) and Shared Decision-Making (SDM) have been associated with greater satisfaction, self-control, and less substance use. However, correlates of SDM have not been investigated in this population. METHOD: A cross-sectional analysis was carried out in 214 SUD patients to identify sociodemographic, clinical and psychological correlates of preferences and perceptions about participation in SDM and degree of activation. The Control Preference Scale (CPS), the Shared Decision-Making Questionnaire (SDM-9-Q) and the Patient Activation Measure (PAM) were used to assess the PCC elements. Multinomial logistic regression was used to analyze the correlates of the CPS variables (preferred role, perceived role, and role matching). For SDM-9-Q and PAM, multilevel linear regression was used. RESULTS: Preferring an active role, compared to a shared one, was significantly associated with higher educational level, lower neuroticism, absence of affective and alcohol use disorders, and higher quality of life. Perceiving greater participation was significantly associated with not being a new patient, having fewer legal problems, higher severity of alcohol consumption, not presenting polydrug use and main substance use different than opioids or sedatives. Activation was associated with higher scores in the personality trait activity, a preference for an active role and greater perception of being involved in the decision process. CONCLUSIONS: Patients with milder clinical profiles prefer an active role compared to a shared one. Patients who prefer or perceive a shared or passive role did not show relevant differences. Greater activation was related to preference for an active role and the perception of having been involved in decisions.

Shared decision making in patients with substance use disorders: A one-year follow-up study.

Patient-centered care in therapeutic processes has been associated with better clinical outcomes, however, it remains a poorly studied aspect in Substance Use Disorder (SUD). The study aimed to evaluate patient's preferences, perceived participation in treatment decisions and activation level; and how they predict retention, pharmacological adherence and substance use during one-year follow-up. Logistic regression models were used to analyze the association between independent variables, along with a wide number of sociodemographic and clinical covariates, and outcomes. Most patients prefer a shared or passive role when making decisions about their treatment, and showed concordance between their preferred and perceived roles. In the univariate models, perceiving more involvement than desired showed a higher likelihood of treatment discontinuation at 12 months, and substance use at 6 and 12 months. No significant associations were found between the remaining decisional variables or the degree of activation with the assessed outcomes. A majority of SUD patients prefer and perceive to be involved in the decision-making process about their treatment. Patients perceiving more involvement than desired might experience an excess of responsibility that could negatively influence treatment continuation and substance use. Limitations of the study preclude any definitive conclusion, and more research is needed to confirm these results.
