It's generally understood that way in psychology. The term "narcissistic supply" is used for the constant approval and praise and adulation that narcissists crave, and the symptoms of its revocation are similar to some forms of drug withdrawal. A narcissist who is confronted or even just cut off will often fly into a blind rage or revert to what seems like an early childhood state of mind and throw tantrums. There's some evidence that neglectful or abusive parenting during certain developmental phases might predispose one to it, basically creating a very deep emotional imprint of "you aren't good enough and must constantly earn love." There's probably more to it than that but I could see that being a factor. For adults there's probably also an ideology / belief system dimension.
