First, two researchers read the transcriptions a number of times, in order to familiarize themselves with the content. A random sample of eight transcripts was selected. Each researcher independently identified the units of meaning in relation to the object of study.

These barriers include lack of self-discipline, procrastination (i.e. putting off till tomorrow what can be done immediately) and the fact of not considering the AP as a priority.
