Frequently Asked Questions

What is the LODHI-A?

The LODHI-A is a semi-structured clinical interview guide for comprehensive adult ADHD assessment. Its full name — Longitudinally Oriented Diagnostic Historical Interview — ADHD — reflects its core methodology: tracing the developmental trajectory of symptoms across the patient's entire lifespan through naturalistic clinical conversation.

How is the LODHI-A different from the DIVA-5?

The DIVA-5 provides examples of each symptom for the patient to identify with — a recognition task. The LODHI-A never supplies examples; the patient must generate their own evidence of impairment — a recall task.

Who can administer the LODHI-A?

Licensed mental health professionals who conduct diagnostic evaluations: psychiatrists, primary care physicians, psychologists, psychiatric nurse practitioners, physician assistants, LCSWs, LPCs, LMHCs, LPCCs, and other clinicians trained in diagnostic assessment.
