If the goal is to boost your CV, there are countless legitimate local/state/regional/national psych associations to join and participate. Additionally, tons of APA and non-APA interest groups are based on interests, subfield specialities, work settings, etc.
Didn’t look up this one but if the main condition to join is paying a membership fee, then it will probably do more harm than good. Psi Chi was by nomination and only a very small percentage of psych majors at an institution gain membership.
