Thank you for asking. External validity aims to improve the representativeness of samples, while internal validity is for establishing the causality of one intervention or policy, and it usually happens in a longitudinal design.

Hi, I am afraid I disagree with a previous post that “the pandemic will worsen hidden youth’s situation.” You see, now everyone is asked to stay at home, and hidden youth no longer face pressure from their parents or society to go out, which might reduce their stress level.

The outbreak of coronavirus pandemic and social distancing measures might make “hidden youth” even more isolated from society.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?

I have designed a large-scale survey about the life satisfaction of low-income families in Hong Kong. Is it appropriate to use the electronic survey through mobile phones?
