Effects of a hybrid digital Cognitive Behavioural Therapy for Insomnia and Emotion Regulation in the workplace

Introduction: This trial tests the efficacy of implementing a hybrid digital cognitive behavioural therapy for insomnia (dCBT-I) and emotion regulation (ER) in the workplace. The study protocol follows on the SPIRIT (Standard Protocol Items for Randomized Trials) 2013 recommendations.
Methods and analysis: Mixed methods evaluation with a two-arm randomised waitlist control design of a six weeks dCBT-I+ER intervention through self-guided online platform and four videoconferencing therapy sessions. A process evaluation will examine fidelity of delivery and experiences of the intervention. Primary outcomes are the Insomnia Severity Index (ISI), the Patient Health Questionnaire (PHQ-9) and the Generalised Anxiety Disorder (GAD-7). Secondary outcomes are job productivity, job satisfaction, well-being, quality of life, self-reported (sleep diary data) and objective (actigraphy) sleep parameters, and usage of online intervention platform. Assessments take place at baseline (T0), week-8 post-treatment (T1), and week-12 post-randomisation (T2). We will recruit 156 workers with sleep and emotion regulation problems ranging from subclinical to clinical levels not engaged in treatment at the time of the trial.
