Of the 173 academic articles, the research designs used were varied (Figure 7a). Quantitative (69.4%), qualitative (28.9%), and longitudinal/cohort (22.0%) research designs prevailed. Other, less frequently used, research designs in these studies were mixed methods (9.8%) and case studies (4%). The 'other' category (10.4%) is made up of studies that analyze policies or discuss theoretical frameworks. Figure 7b presents varied nature of research design that guided the grey literature studies. Quantitative designs predominate (56.0%) but less so than in the academic literature; 43.9% of the grey literature employed a qualitative design, 7.9% case studies and 6.1% mixed method research.
