A triangulation model using semi-structured interviews, observations, narratives, and/or reflective writing brought together data from a longitudinal perspective involving 6-month monitoring of Derviş’ knowledge, beliefs, and practices. Derviş’ practices and reported beliefs were documented and analysed over six months.
