Sleep and productivity benefits of digital cognitive behavioural therapy for insomnia: a randomised controlled trial conducted in the workplace environment

Abstract:

Objective: Evaluating digital Cognitive Behavioural Therapy (dCBT) for insomnia in a workplace environment.

Methods: Within a randomized controlled trial in a Fortune 500 company, we randomized 270 self-identified poor sleepers [180M/90F: mean age 33.6y (23-56y)] to dCBT (n=135) or waiting list (WL, n=135). dCBT comprised 6 online sessions delivered by an animated therapist. Major assessments were at baseline and post-treatment.

Results: Sleep Condition Indicator (SCI) scores were significantly higher for the dCBT group [interaction term: F(1,485) = 15.63, p<.0001], representing Cohen’s d of 1.10 following dCBT (d=0.34 for WL). On the Work Productivity and Impairment questionnaire, ‘presenteeism’ demonstrated significant improvements following dCBT [F(1,485)=10.99, p=0.001: d =0.64 for dCBT, d =0.09 for WL]. Effects for ‘abseenteeism’ failed to reach statistical significance (p=0.101).

Conclusions: dCBT is effective in improving sleep and work-based productivity in adults with insomnia.
