I found this pdf of the Aspects of Identity Questionnaire-IV which mentions the scoring for the dimensions of the scale. I am unsure as to what the scores mean once they've been totalled.
Is this scale only used to determine which orientation an individual scores highest on? They do define identity orientations as "the relative importance that individuals place on various identity attributes or characteristics when constructing their self-definitions".
