Strengths
First, the diverse demographic backgrounds (e.g. age, economic level, and area of residence) of the included participants increased the generalizability of this project. Second, two purposive sampling methods (homogeneity and purposeful random sampling) were combined for sample selection. Homogeneity enabled the description of a particular subgroup in depth, reduced variation, and allowed for accurate statistical analysis. Meanwhile, purposeful random sampling increased the credibility of results by including heterogeneous participants. Third, all participants were coded and advised to turn off their cameras during the video discussion, thus, encouraging them to talk openly about their experiences, especially regarding some certain sensitive topics, in front of others.
