According to time horizons, research projects may be cross-sectional or longitudinal. Cross-sectional research is described as research investigating a phenomenon at a particular time, whereas a research investigating a change and development over a time is called Longitudinal (Saunders et. al,2012). In this study, the time horizon is cross sectional. It was also not possible to access all Saudi schools for a longitudinal study. Furthermore, there were time limitations and a schedule for the completion of the study.
