Caregiver Stress and Mood Screening Tool

Caregiver Stress and Mood Screening Tool

The Caregiver Strain Index & PHQ-2 is a combined screening tool that pairs two validated instruments to support a comprehensive picture of caregiver well-being. The Caregiver Strain Index is a standardized tool used to assess caregiver stress and perceived burden, while the PHQ-2 is a brief, two-item questionnaire used to screen for mood-related symptoms, including depressed mood and loss of interest. Together, they provide structured, efficient documentation of caregiver mental and emotional health in clinical settings.

Delivered digitally through the BrainCheck platform, this combined screener can be completed in approximately 1–3 minutes by a caregiver, either in-clinic or remotely, and supports identification of caregivers who may benefit from additional support or resources.

Benefits include:

  • Combines two validated instruments into a single, efficient caregiver screening workflow.
  • Identifies caregiver strain and mood concerns that may require additional support or intervention.
