© 2016 Elsevier Ireland Ltd Objective In clinical practice, methadone maintenance treatment (MMT) entails tailoring the methadone dose to the patient's specific needs, thereby individualizing treatment. The aim of this study was to identify the independent factors that may significantly explain methadone dose adequacy from the patient's perspective. Method Secondary analysis of data collected in a treatment satisfaction survey carried out among a representative sample of MMT patients (n = 122) from the region of La Rioja (Spain). As part of the original study protocol, participants completed a comprehensive battery to assess satisfaction with MMT, psychological distress, opinion of methadone as a medication, participation in dosage decisions, and perception of dose adequacy. Results Multivariate binary logistic regression showed that the only variable independently associated with the likelihood of a patient perceiving methadone dose as inadequate was the variable perceived-participation in methadone dosage decisions (OR = 0.538, 95% CI = 0.349–0.828). Conclusion Patient participation in methadone dosage decisions was predictive of perceived adequacy of methadone dose beyond the contribution of other socio-demographic, clinical, and MMT variables. Practice implications Patient participation in methadone dosage decision-making is valuable for developing a genuinely patient-centred MMT.
