-has very few concepts that can be reduced to single variables & measured, so may be short on empirical evidence to support it's claims
-ethnocentric: ideas are associated with individualist cultures & collectivist cultures may not identify with the ideals & values, so doesn't apply universally & is a product of the culture it was developed in
-has limited impact in psychology / real world application compared to other approaches, may be due to fact it lacks sound evidence / has been described as a loose set of abstract concepts
-includes a number of vague ideas that are abstract & difficult to test, concepts, eg. self-actualisation may be useful therapeutic tools but are difficult to asses under experimental conditions, so is short on empirical evidence to support its claims
-CCT is of limited help for those with complex / severe problems, best applied to the treatment of 'mild' psychological conditions
