Different questions need different evidence
A relationship pattern is often clearer in scenarios. A regulation state may be clearer through body cues. Values become clearer when tradeoffs are forced. Symbolic material belongs in reflection, not diagnosis.
Using the same questionnaire format for every domain would make the product simpler, but less honest about what each construct can support.
Limitations are part of the method
Every assessment states what it can suggest and what it cannot claim. Those boundaries are not disclaimers added at the end; they are part of the interpretation.
When the stakes are high, use the result as a prompt for support, not as a final answer.
