iOS 18 Health App Mental Health Assessment Tools

Apple's iOS 18 integrates clinically validated mental health assessments directly into the Health app, allowing users to evaluate their risk for common conditions like depression and anxiety. This article details the specific assessment questionnaires available, how mood-tracking complements these tools, and how users can securely access, complete, and export their results to support proactive mental healthcare.

Clinically Validated Questionnaires

The iOS 18 Health app incorporates two standardized, widely recognized screening questionnaires used by healthcare professionals worldwide:

1. PHQ-9 (Patient Health Questionnaire-9)

The PHQ-9 evaluates the user's risk level for depression.

  • Focus: It asks nine questions regarding symptoms experienced over the past two weeks, including loss of interest, sleep disturbances, fatigue, changes in appetite, and feelings of hopelessness.
  • Scoring: The results categorize risk into standard clinical tiers: None/Minimal, Mild, Moderate, Moderately Severe, or Severe.

2. GAD-7 (Generalized Anxiety Disorder-7)

The GAD-7 measures the user's risk level for generalized anxiety disorder.

  • Focus: It consists of seven questions assessing how frequently a user has been bothered by problems such as feeling nervous, uncontrollable worrying, trouble relaxing, and irritability over the preceding two weeks.
  • Scoring: Results are stratified into risk bands: None/Minimal, Mild, Moderate, or Severe.

State of Mind Tracking

Working in tandem with standardized questionnaires, iOS 18 includes a "State of Mind" tracking tool. While not a clinical diagnosis, this feature provides context for the assessments.

  • Momentary Emotions: Users can record how they feel at any specific moment using a multidimensional slider ranging from "Very Unpleasant" to "Very Pleasant."
  • Daily Mood: Users can summarize their overall mood for the day.
  • Contextual Tagging: Each entry allows the user to log associations, such as work, family, fitness, or sleep, helping identify lifestyle factors that influence emotional states.

How to Access and Use the Assessments

To take an assessment in iOS 18:

  1. Open the Health app on an iPhone running iOS 18.
  2. Tap the Browse tab and select Mental Wellbeing.
  3. Scroll to the Mental Health Assessments section.
  4. Select Take Assessment to complete the PHQ-9 or GAD-7.

Users can also enable periodic assessment reminders, prompting them to retake the screenings every few months to track changes over time.

Data Sharing, Privacy, and Crisis Support

  • Exportable Clinical Reports: Assessment results can be exported as a secure PDF. This document displays the calculated score alongside the question breakdown, allowing users to share structured data with a doctor or therapist.
  • Crisis Resources: If an assessment score indicates a high risk—or if a user indicates thoughts of self-harm on question 9 of the PHQ-9—the Health app immediately provides access to recognized crisis support resources, hotlines, and text services.
  • Privacy and Encryption: All mental health data, including questionnaire answers and mood entries, is encrypted on-device. When synced with iCloud using two-factor authentication, it is protected via end-to-end encryption and cannot be read by Apple.
