From a biopsychosocial perspective, assessing chronic pain's psychological impact should involve at minimum the measurement of pain severity, functional interference, and pain-related emotional burden. This article details the development of a brief instrument, the 15-item Profile of Chronic Pain: Screen (PCP:S), designed to address these three key elements in a national (US) sample of over 240...

BACKGROUND There is increasing debate about cannabis use for medical purposes, including for symptomatic treatment of chronic pain. We investigated patterns and correlates of cannabis use in a large community sample of people who had been prescribed opioids for chronic non-cancer pain. METHODS The POINT study included 1514 people in Australia who had been prescribed pharmaceutical opioids for...

OBJECTIVE This study aimed to measure the outcomes that patients consider clinically meaningful across four treatment domains - (1) pain, (2) fatigue, (3) emotional distress, and (4) level of interference - and determine if patients met their own success criteria. Additionally, the role of expectations in treatment outcome was examined. This study also aimed to determine how change in levels of...

The value of chronic opioid therapy (COT) for chronic non-cancer pain (CNCP) patients is determined by a balance of poorly understood benefits and harms. Traditionally, this balance has been framed as the potential for improved pain control versus risks of iatrogenic addiction, drug diversion, and aberrant drug-related behaviors. These potential harms are typically defined from the providers' p...

Background Pediatric chronic pain often emerges in adolescence and cooccurs with internalizing mental health issues and sleep impairments. Emerging evidence suggests that sleep problems may precede the onset of chronic pain as well as anxiety and depression. Studies conducted in pediatric populations with pain-related chronic illnesses suggest that internalizing mental health symptoms may media...

This study aimed to investigate the individual effects of chronic stress and occlusal interference, as well as their combined influence on masseter muscle pain. Experiments were performed on 28 male Wistar rats. Animals were submitted to chronic stress procedure, exposed to occlusal interference, or exposed to both mantioned procedures. At the end of the procedure animals were submitted to orof...

BACKGROUND Postherpetic neuralgia (PHN) develops in 8-24% of patients with herpes zoster. Few studies have evaluated the patient burden and treatment of PHN in general practice. OBJECTIVES To determine the patient burden of PHN with respect to pain intensity and impact on patient functioning and to characterise treatment patterns and health resource utilisation in general practice. METHODS ...

BACKGROUND The primary aim of this work was to present the prevalence data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a representative 3-year longitudinal survey (ages 18+ years) that captured information on patterns of self-reported pain interference and prescription pain reliever misuse. A second aim was to assess the degree to which the risk of various...
