Twenty-nine PhD students/young PhD graduates (bellow 45 years old) that were also practicing GPs (or GP Trainees) were approached by email to participate in the study. To the best of the author's knowledge they represent the Portuguese national sample.</p><p id="par0020" class="elsevierStylePara elsevierViewall">The questionnaire on supervisor–doctoral student interaction (QSDI), an instrument developed to study the supervisor–student relationship,<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">2</span></a> was available for filling in online. It was administered in English. Participants were instructed to fill in two versions of the QSDI: one asking for the experienced supervisor behaviour and the other for the preferred/ideal behaviour. For each question a 5-point Likert scale (from never/not at all to always/very) was used. The questionnaire was completely anonymous.</p><p id="par0025" class="elsevierStylePara elsevierViewall">Standard descriptive analyses were performed.

Even so, the response rate of 65.5% was adequate. Future research with larger samples will be possible as increasing numbers of GPs enrol in PhD programmes. For example, it would be worthwhile to study if the immaturity in the professional career as a GP could change the ideal supervisor behaviour (i.e. a needier supervised). Investigating the supervisors’ behaviour from their own point of view will also be an important effort for understanding the full spectrum of the relationship.</p><p id="par0055" class="elsevierStylePara elsevierViewall">Although any extrapolation of the results should be done with caution, the current study found that the PhD supervisor profile in primary care is not different from the profile found in other settings.
