This questionnaire is designed to be completed by adults and adolescents based on their recent emotional and psychological experiences during the past two weeks.

Participants select the response option that best describes how often they have experienced each symptom or emotional difficulty.

The assessment focuses on depressive symptoms, emotional well-being, sleep, appetite, concentration, motivation, and suicidal thoughts during recent functioning.

This assessment is intended for educational, screening, and research purposes only.

Results should not be considered a clinical diagnosis or substitute for professional psychological, psychiatric, or medical evaluation.

Individuals experiencing severe emotional distress, hopelessness, suicidal thoughts, or major impairment in daily functioning are strongly encouraged to seek support from a qualified mental health professional or healthcare provider.

Responses are scored on a 0–3 scale according to symptom frequency.

Higher scores generally indicate stronger depressive symptoms, emotional distress, fatigue, cognitive difficulties, hopelessness, and functional impairment.

The PHQ-9 is commonly used as a screening tool to help identify individuals who may benefit from additional psychological or psychiatric evaluation.

Little interest or pleasure in doing things.

Feeling down, depressed or hopeless.

Trouble falling asleep, staying asleep, or sleeping too much.

Feeling tired or having little energy.

Poor appetite or overeating.

Feeling bad about yourself - or that you’re a failure or have let yourself or your family down.

Trouble concentrating on things, such as reading the newspaper or watching television.

Moving or speaking so slowly that other people could have noticed. Or, the opposite - being so fidgety or restless that you have been moving around a lot more than usual.

Thoughts that you would be better off dead or of hurting yourself in some way.
