}

Seems like a break of the DRY principle. Why not have a way to define a constraint as a global constant than can be reused across the domain model.
This could be modelled something like the following.

Config.groovy
===========
grails.model.global.constraints = [
Five : [range: 1..5]
...
]

PersonalityTraits.groovy
===================

class PersonalityTraits {
@constraint Five
int mindFulness

@constraint Five
int listener
...
}

OR by allowing grouping of properties with same constraint type

class PersonalityTraits {
int mindFulness
int listener
...

static constraintConfig = { Five(mindFulness, listener, ...) }

static sortOrder = { mindfulness() listener() ... }
}
