Roche & Lark Health’s Pilot Study on Cardiac Self-Efficacy

Roche has collaborated with Lark Health on the pilot study “Cardiac Self-Efficacy Improvement in a Digital Health Pilot Program for Heart Health” to help patients prevent and manage heart disease by targeting Cardiovascular Disease risk factors.

The Project 


Behaviour change programs focused on leading a healthy lifestyle can play a critical role in preventing and managing cardiovascular disease risk. A component of this relies on helping patients develop a sense of self-efficacy around managing their cardiovascular health, which can include educational materials, care coaching, and behaviour change.


The 90-day pilot study by Lark Health in collaboration with Roche first helped participants identify their own personal risks for developing CVD, and then provided them with AI-powered care coaching and educational lessons focused on behaviours that reduce those risks and promote better heart health.

Goals of the study:

Demonstrate members’ continued engagement with risk assessment surveys, in-app coaching activities, device measurements to improve cardiac self-efficacy and reduce cardiovascular risk.

Results of the study:

As part of the study, after 40 days in the Heart Health program, 272 participants on average showed an increase in overall cardiac self-efficacy (as measured by the 9-item cardiac self-efficacy scale).

For the reference:

The overall sum score of the scale and all 9 individual items showed significant improvements: in knowing:

  • when to call or visit a doctor about your heart disease,
  • how to make a doctor understand your concerns about your heart,
  • how to take your cardiac medications,
  • how much physical activity is good for you.

    and feeling confident in being able to maintain:
  • your social activities
  • your usual activities at home with their family,
  • your usual activities at work,
  • your sexual relationship with their
  • and get regular aerobic exercise.

These three items showed the largest increase:

  • knowing when to call or visit the doctor for your heart disease,
  • knowing how much physical activity is good for you,
  • that you can get regular aerobic exercise.
