“…Nonadherence to prescribed medication remains the major problem faced by health care systems when managing chronic diseases, becoming a missed opportunity for improvement of health outcomes, a waste of resources, and a possible explanatory factor for high mortality and morbidity . Medication adherence refers to the patient's compliance with the provider's recommendation with respect to timing, dosing, and frequency of medication taking during the prescribed length of time…”

Aim: The aim of present study was to perform the translation, cultural adaptation, and validation of the Medication Adherence Report Scale (MARS-P9) for the European Portuguese language in a sample of chronic pain patients. Methods: A Portuguese version of the nine-item MARS (©Professor Rob Horne) scale (MARS-P9) was constructed through a process of translation, back translation, and experts' panel evaluation. A total of 141 chronic pain patients were subsequently evaluated at four time assessments during a 1-year pain medication treatment. The protocol interview included the assessment of pain intensity and interference (BPI), clinical outcomes and quality of life (S-TOPS), and MARS-P9.Results: The internal consistency coefficient was acceptable for the total scale (α = 0.84). Exploratory factor analysis revealed a two-factor structure (intentional and unintentional nonadherence) that explained 61% of the variance. Convergent and discriminant validity were demonstrated by correlations between MARS scores and pain interference (r = 0.180, P ≤ 0.01) and S-TOPS (r = 0.242, P ≤ 0.05).Conclusion: MARS-P9 has been shown to be an adequate instrument for Portuguese researchers and clinicians to assess the pattern of adherence during the management of chronic pain. ;25:346-352. wileyonlinelibrary.com/journal/jep the provider's recommendation with respect to timing, dosing, and frequency of medication taking during the prescribed length of time. 15 Despite the effectiveness of pain medicines, they are quite often misused, with almost 50% of medication not taken as prescribed. 13 Moreover, an important recent Portuguese study that analysed the direct and indirect costs associated with chronic pain revealed a total €481.59 million of annual costs for the Portuguese population (95% CI [423.63 to 552.68]) associated with pain medicines. 16Since the WHO Adherence meeting in 2001, it is well accepted that there is no "gold standard" for measuring adherence behaviour. However, it is recognized that using questionnaires meeting basic psychometric standards, to assess specific behaviours related to specific medical recommendations, allows a better prediction of the adherence behaviour. 15 The Medication Adherence Scale (MARS) (©Professor Rob Horne), developed in England, is a feasible self-reporting scale addressing nonadherence behaviour in a nonthreatening and nonjudgmental way, which may result in truthful answers, used in a range of long-term conditions. This is a generic tool, which can be used to assess any prescribed drug regardless of the health condition. Adherence is measured as a continuous scale, rather than dichotomous adherent/nonadherent categories, producing an ordinal instead of an interval-scale assessment. The MARS (©Professor Rob Horne) has been validated in different languagesin different clinical settings and countries and is available in 5, 9, and 10 items. 17-23 All versions contain a common set of five items (MARS-5), eg, "I forget to take my medicines". In other versions, condition-specific items are adde...
