About This Assessment
The DOI Assessment explores a question clinical research has consistently raised: is what you're experiencing a disorder — or evidence of exceptional cognitive and emotional processing operating under strain?
Cognitive Problem-Solving
10 logic, pattern recognition, and lateral thinking questions. Scored correct or incorrect. Question order and option order are randomised every session.
Emotional Intelligence
10 situational judgment questions. Each option scored 0–3 on EI quality. Options shuffled per session.
Anxiety Profile
10 frequency-based questions producing an independent measured result with recovery guidance where anxiety is detected.
Integrity Verification
Cognitive questions track response time. Answers given significantly faster than the minimum reasonable time for that question type are flagged and shown in your integrity score on the results page. Because question order and option order are randomised each session, positions cannot be memorised from a previous attempt.
