Anxiety & Stress Level Screener (GAD-7 Based)

The GAD-7 (Generalized Anxiety Disorder 7-item scale) is a validated self-report questionnaire used to screen for and measure the severity of generalized anxiety disorder. Rate how often you have been bothered by each problem over the last 2 weeks.

Rating Scale: 0 = Not at all  |  1 = Several days  |  2 = More than half the days  |  3 = Nearly every day

1. Feeling nervous, anxious, or on edge

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Not being able to stop or control worrying

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Worrying too much about different things

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Trouble relaxing

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Being so restless that it is hard to sit still

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Becoming easily annoyed or irritable

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. Feeling afraid as if something awful might happen

-- Select -- 0 – Not at all 1 – Several days 2 – More than half the days 3 – Nearly every day

1. How difficult have these problems made it to do your work, take care of things at home, or get along with other people?

-- Select -- Not difficult at all Somewhat difficult Very difficult Extremely difficult

#### Formula

GAD-7 Total Score = Q1 + Q2 + Q3 + Q4 + Q5 + Q6 + Q7

Each item is rated 0–3: 0 = Not at all, 1 = Several days, 2 = More than half the days, 3 = Nearly every day

Score Range: 0–21

Score Range Severity Suggested Action

0 – 4MinimalMonitor; self-care strategies 5 – 9MildWatchful waiting; consider counseling 10 – 14ModerateConsult healthcare provider; consider CBT/medication 15 – 21SevereSeek professional help promptly

Clinical Cut-Point: Score ≥ 10 indicates likely GAD (Sensitivity: 89%, Specificity: 82%).

Question 8 (functional difficulty) is not added to the GAD-7 total score but provides important context about functional impairment.
