Data analysis
SPSS Statistics 20 was used to analyse data obtained from the questionnaire and to calculate descriptive statistics of the focus group sample. Data obtained from the audio tapes where transcribed verbatim in Microsoft Word using Express Scribe and Windows Media Player. All quotes were encoded using the qualitative software program Nvivo9. Using an inductive thematic approach, data (quotes) were examined for recurrent instances of some kind, which were then systematically identified across the data set, and grouped together by means of a coding system (= content analysis). Similar codes were grouped together into more general concepts (subcategories) and further categorised into main categories. To ensure reliability of data interpretations, analyses were carried out independently by two researchers. Doubts or disagreements were discussed with two other researchers until consensus was reached.
Results
In this study, the estimated point of saturation was observed after the fourth focus group session. One additional focus group discussion was conducted to be sure true saturation was established. In total, five focus group discussions have been conducted, consisting of five to ten participants per group. The sample (n = 35) consisted of 14 male and 21 female students with a mean age of 20.6 ± 1.7 yrs (range = 18-26 yrs) and a mean study career of 3.0 ± 1.0 yrs. The majority of students
