Chronic Pain Sleep Inventory (CPSI)
Pain and Sleep Questionnaire (PSQ-3)
The Chronic Pain Sleep Inventory© (CPSI©), sometimes referred to as the Pain and Sleep Questionnaire© (PSQ-3©) is a 5-item proprietary self-administered sleep questionnaire protected by copyright. It is a widely used tool to evaluate the role of pain in sleep interference, both in analgesic clinical trials and clinical practice. CPSI Version 2.0 (CPSI-3©), sometimes referred to as PSQ-3© uses 3 of the 5-items where all items attribute sleep problems to pain to form a unidimensional construct. The preferred name of this instrument is Chronic Pain Sleep Inventory© (CPSI©) or CPSI Version 2.0 (CPSI-3©).
Why Assess Sleep in Analgesic Clinical Trials?
Patients with chronic pain, including cancer pain, musculoskeletal pain (e.g., osteoarthritis, low back pain), fibromyalgia and neuropathic pain (e.g., painful diabetic neuropathy, postherpetic neuralgia and painful HIV associated neuropathy) frequently present with a wide variety of comorbid pathologies that may or may not be causally related to their chronic pain. Self-reports and polysomnographic findings have long suggested that sleep disturbances are common in patients with chronic pain, with higher pain intensity scores correlating with greater sleep impairment. However, until relatively recently, efficacy outcomes in clinical trials focused only on relief from pain, joint stiffness and improvements in physical function. Furthermore, there was little information on the epidemiology of sleep disturbance in chronic pain and on the effects of analgesic treatment on sleep impairment.
General Description of the CPSI and PSQ-3
The CPSI and CPSI Version 2.0 (CPSI-3), sometimes referred to as the Pain and Sleep Questionnaire (PSQ-3) are proprietary sleep questionnaires protected by copyright. They were developed in the English language (U.S.) and have undergone translation in approximately two dozen languages. They have been used to successfully document the effects of therapeutic interventions on various sleep characteristics in randomized clinical trials by numerous pharmaceutical companies and included in New Drug Applications (NDAs) as VAS and Lickert scales, in paper and electronic form.
Available Languages
The Chronic Pain Sleep Inventory© (CPSI©) and the CPSI Version 2.0 (CPSI-3©), sometimes referred to as PSQ-3© was developed in English for the USA and is available in 23 languages. The listed translations may not have undergone a full linguistic validation process and may require further work to be suitable for use in a study.
