By the way, I found that if using quantitative methods, I could hardly hear how the older adults themselves interpreter their experiences about sexual needs or other related services. Shall I add in-depth interviews in data collection?Hi! I recently got to know the concept “asynchronous communication”. It refers to when two (or more) people can communicate without the requirement that they are “present” at the same exact moment in time. Nowadays, in online youth services, there are synchronous and asynchronous communications. For hidden youth, it seems asynchronous communication allows more convenience for them. May I know your opinions about it?
