Measures clients actually finish: window timing over questionnaire choice

Debates about PHQ-9 versus alternatives miss the operational truth: the biggest driver of measure completion is when the window opens, not which instrument you chose.

Three timing rules

• Open the window 48 hours before the session, not a week
• Close it the morning of the session so data is fresh
• Remind once — a gentle push notification, never a guilt trip

Fresh scores change the session that follows them. Stale scores are trivia.
