The use of Actiwatch with CBTI

The Actiwatch device collects objective sleep/wake data from patients enrolled in the CBTI program.

Qualitative assessment

The device, worn 24/7 on the wrist, records movement, light exposure, and event marking information over several weeks. Results can be analyzed qualitatively using actograms (24-hour chart plots of activity and light information). The CBTI program provides you with a structure to analyze actograms, along with patient sleep logs for the following characteristics of a patient’s sleep/wake schedule:

  • Rhythmicity: Is sleep occurring in the appropriate time window within the 24-hour clock?
  • Consolidation: Does sleep occur in continuous, uninterrupted blocks, or is there fragmentation or interruption by activity bouts?
  • Regularity: Are the bedtimes and wake-times relatively consistent? Is the patient conforming to sleep restriction bedtimes?
  • Napping: Are short periods of rest or naps occurring that might impact the patient’s ability to sleep at night?

Quantitative assessment

The actigraphy report provides a summary table of quantitative outcomes used early in the program to help assess patient compliance and document sleep quantity and quality using sleep time and efficiency measures. The values from the actigraphy report are transferred to the sleep restriction worksheet in order to recommend an appropriate sleep restriction schedule for the patient.



The Actiwatch family of devices is designed to help you better understand a subject’s daily activity and sleep/wake patterns in response to drug or behavioral therapies.
