TL;DR
In this study, data saturation was most certainly reached for samples >150 participants and the method may be used to determine when to continue the study to find new themes or stop because of futility.
Abstract
In our study, data saturation was most certainly reached for samples >150 participants. Our method may be used to determine when to continue the study to find new themes or stop because of futility.
