Mental Health Questionnaires and Assessment Tools

Depression questionnaires: PHQ-9 and HDRS

Patient Health Questionnaire-9 (PHQ-9)

The PHQ-9 asks nine questions about how you have been feeling over the past two weeks. It covers concerns such as feeling low, losing interest in things, changes in sleep or appetite, and low energy. You fill it out based on your own experience.

Your answers help us talk about symptoms and how they affect daily life. Repeating the questionnaire later can help us notice what is improving and what still needs attention.

Hamilton Depression Rating Scale (HDRS or HAM-D)

The HDRS looks more closely at depression symptoms, including mood, sleep, appetite, and physical symptoms. This practice's form includes 17 items. The scale was designed for a clinician to rate; any information you provide on the form is a starting point for my review and discussion with you.

Anxiety questionnaire: GAD-7

Generalized Anxiety Disorder-7 (GAD-7)

The GAD-7 asks seven questions about anxiety over the past two weeks, including worry, tension, restlessness, and trouble relaxing. You describe how often these feelings have been happening.

It helps us start a conversation about anxiety and follow changes over time. We also discuss your experiences in more detail, including concerns that the questionnaire may not capture.

Obsessive-compulsive symptoms: Y-BOCS

Yale-Brown Obsessive Compulsive Scale (Y-BOCS)

The Y-BOCS explores unwanted thoughts that keep returning and actions you feel driven to repeat. It asks how much time these experiences take, how upsetting they are, and how they interfere with your life.

The website form gathers your description of these symptoms. I review your answers with you to understand your experience more fully. The original scale was designed for a clinician-led interview; completing an online form does not by itself diagnose OCD.

Adult ADHD assessment: ASRS-v1.1 and DIVA-5

Adult ADHD Self-Report Scale (ASRS-v1.1)

This 18-question form asks about attention, organization, restlessness, and acting without thinking. You answer based on your own experiences. It can help identify concerns to explore during an ADHD evaluation, but it cannot diagnose ADHD on its own.

Diagnostic Interview for ADHD in Adults (DIVA-5)

DIVA-5 is a structured interview that explores ADHD symptoms in adulthood and childhood, and how they have affected different parts of your life. Examples from school, work, relationships, and daily routines can help bring your experience into focus.

The website form lets you share examples ahead of our discussion. I review them with you as part of a clinical evaluation, including other possible reasons for attention difficulties.

Adult ADHD Collateral Informant Questionnaire

An “informant” is simply someone who knows you well, such as a partner, family member, or close friend. With your agreement, I may ask that person to describe what they have noticed about your attention, behavior, and everyday challenges.

Their observations add another perspective to your own story. This form is not a separate diagnostic test, and they can say when they do not know an answer.

What to expect

I will let you know which questionnaires to complete and how to access them. Answer as honestly as you can. If a question does not quite fit your experience, or you are unsure how to answer, we can talk about it together.

We review what your answers mean in the context of your life. They may help us decide what to explore next and discuss your care options. During treatment, I may recommend repeating some symptom questionnaires to see how you are doing.

Your usual registration and consent paperwork is separate from these assessment tools.
