Evaluation of the effectiveness of cognitive-behavioural therapy for insomnia delivered by nurses and physicians for patients in primary care (the NPD study): protocol for a cluster randomised controlled trial.

Introduction: Insomnia is the most common sleep disorder, and it adversely impacts daily living and increases the risk of chronic and acute health problems. Of the few individuals who seek treatment for insomnia, most pursue help in primary care settings. The management of insomnia most commonly focuses on the prescription of hypnotics and sleep hygiene recommendations, although these are not the most effective treatments.

Assessing the feasibility and acceptability of a cluster-randomized study of cognitive behavioral therapy for chronic insomnia in a primary care setting.

Background: Cognitive behavioral therapy for chronic insomnia (CBT-i) is the treatment of choice for this condition but is underutilized in patients who attend primary care. The purpose of the present feasibility-pilot study was to assess the feasibility and acceptability of a cluster-randomized study of CBT-i in a primary care setting.

Methods: This study, performed at two primary health care centers in Majorca, Spain, was a mixed methods feasibility-pilot study of a parallel cluster-randomized design comparing CBT-i and usual care (UC).
