My question is if we can close questions asking for equivalences between Judaism and psychological theories as cognitive psychologies or other therapies, as questions asking about comparative religions. My opinion is that is the same category of questions.
I'd recommend applying a similar standard to the one proposed in the highest-voted answer to our original Meta question about comparative religion: If the question asks "What does Judaism think of X precept of this other system?", it's likely on-topic, but bear in mind the quality issues that can come with questions of that form. If the question is "compare and contrast Judaism's and this other system's approach to X," that requires expertise in the other system and is therefore likely off-topic unless the question includes all of the necessary information about the other system.
