Adult ADHD Self-Report Scale
Measures: ADHD Symptoms
An 18-item scale that evaluates both inattentive and hyperactive-impulsive symptoms of ADHD in adults. It sets your baseline symptom severity and tracks improvement throughout treatment. Part A (6 items) is a screener: a high score means ADHD is worth a closer look. The diagnosis itself comes from your provider at the evaluation, not from a score.
Questions: 18 items
Focus: Inattention, hyperactivity, impulsivity patterns
Barkley Functional Impairment Scale
Measures: Functional Impairment
Measures how ADHD symptoms affect your daily life across work, relationships, self-care, and risk-taking behaviors. Symptom reduction doesn't matter if you're still struggling to function. This scale shows whether treatment is making your life better, not just your scores.
Questions: 15 items
Focus: Real-world functioning in work, social, daily tasks
Social Phobia Inventory
Measures: Social Anxiety
A 17-item scale that assesses fear, avoidance, and physiological symptoms in social situations. Social anxiety often coexists with ADHD and can worsen or improve with stimulant treatment, so your provider tracks which direction it's going.
Questions: 17 items
Focus: Social fear, avoidance behaviors, physical symptoms
Liebowitz Social Anxiety Scale
Measures: Social Anxiety Severity
A more detailed 24-item assessment covering performance situations and social interactions. Your provider uses it alongside SPIN when social anxiety is significant, to track fear and avoidance separately across different contexts.
Questions: 24 items
Focus: Performance anxiety, social interaction fear/avoidance
Patient Health Questionnaire-9
Measures: Depression Severity
The gold standard 9-item depression screener used across medicine. Stimulant treatment can sometimes unmask or worsen underlying depression, or conversely, improving ADHD symptoms can lift mood. This scale keeps your treatment honest about which direction things are heading.
Questions: 9 items
Focus: Depressive symptoms, anhedonia, suicidal ideation
Insomnia Severity Index
Measures: Sleep Quality
A 7-item scale measuring difficulty falling asleep, staying asleep, and daytime impairment from poor sleep. Stimulants affect sleep, anxiety affects sleep, and poor sleep worsens ADHD. This shows whether your treatment plan is helping or hurting your rest.
Questions: 7 items
Focus: Sleep onset, maintenance, daytime consequences
