From my experience and from speaking with mentors, you’ll statistically get more interviews and into much better programs when you take time off between undergrad and grad and work on research. I’ve had people tell me they don’t even consider people who haven’t taken time off. Not to say that it couldn’t happen, I know one person who had a near perfect GRE and got in right from undergrad but I would strongly advise to take time in between. You’ll mature as a person, a researcher, a clinican, etc. Additionally, I would describe “clinical” experience as working face to face with patients and/or people with psychopathology. The rest is more volunteer experience and lets the committee know you’re socially conscious, but this isn’t clinical experience in particular. I volunteer with crisis text line and have done service trips, and I would not say that’s clinical experience.
If you don’t envision research in your future, I would shy away from PhD programs and consider instead PsyD, SW, or MHC degrees. Those all will allow you to be a clinican.
