Objectives Patients' self-report of medicine taking is a feasible method of assessing their adherence to prescribed pharmacological treatment. Aim of this study was to assess whether the German version of the Medication Adherence Report Scale (MARS-D) is an appropriate instrument for measuring patient adherence. Methods After translation into German, the questionnaire was sent to 1488 patients with chronic diseases and patients with risk factors of cardiovascular disease. Reliability and validity of the MARS-D were assessed and compared with the psychometric properties of the original English version. The relationship between patients' characteristics and adherent behaviour was estimated using bivariate correlation and a linear regression model. Results The MARS-D was analysed if patients were taking medicines and the MARS-D was complete leaving 523 (35.1%) analysable questionnaires. Internal consistency of the MARS-D (Cronbach's alpha 0.60-0.69) was satisfactory and comparable to the English original (Cronbach's alpha 0.69-0.90). Test-retest reliability was satisfactory (Pearson's r 0.61-0.63), however, lower than in the English sample (r = 0.97). Convergent validity was low but showed statistical significance. Patient socio-demographic characteristics had weak influence on MARS-D score indicating high reported adherence for older patients (P < 0.05), patients with German mother tongue (P < 0.05) and high number of medicines (P < 0.01). Conclusions Preliminary psychometric evaluation of the MARS-D is encouraging. MARS-D is an appropriate measure to detect patients at risk of non-adherence. The MARS-D could be used in routine care to support communication about the medication taking behaviour, as self-report of non-adherent behaviour corresponds to the facts.

BackgroundIn Germany, there is a shortage of young physicians in several specialties, the situation of general practitioners (GP) being especially precarious. The factors influencing the career choice of German medical students are poorly understood. This study aims to identify factors influencing medical students' specialty choice laying a special focus on general practice.MethodsThe study was designed as a cross-sectional survey. In 2010, students at the five medical schools in the federal state of Baden-Wuerttemberg (Germany) filled out an online-questionnaire. On 27 items with 5-point Likert scales, the students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to assign their intended medical specialty.Results1,299 students participated in the survey. Thereof, 1,114 students stated a current choice for a specialty, with 708 students choosing a career in one of the following 6 specialties: internal medicine, surgery, gynaecology and obstetrics, paediatrics, anaesthetics and general practice. Overall, individual aspects ('Personal ambition', 'Future perspective', 'Work-life balance') were rated as more important than occupational aspects (i.e. 'Variety in job', 'Job-related ambition') for career choice. For students favouring a career as a GP individual aspects and the factor 'Patient orientation' among the occupational aspects were significantly more important and 'Job-related ambition' less important compared to students with other specialty choices.ConclusionsThis study confirms that future GPs differ from students intending to choose other specialties particularly in terms of patient-orientation and individual aspects such as personal ambition, future perspective and work-life balance. Improving job-conditions in terms of family compatibility and work-life balance could help to increase the attractiveness of general practice. Due to the shortage of GPs those factors should be made explicit at an early stage at medical school to increase the number of aspirants for general practice.

The BMQ is a suitable instrument to measure patients' beliefs in medicines in German primary care settings. Most patients in our sample had positive beliefs concerning the necessity of their medication. Their levels of concern were associated with higher non-adherence.
