A principal components analysis of negative affect-related constructs relevant to pain: evidence for a three component structure.

Unlabelled: A number of negative affect-related constructs are important in pain. Some are general, such as anxiety, depression and negative affectivity, whereas others are more specifically pain-related (eg, fear of pain, pain anxiety, and pain catastrophizing). In addition, some more specific fear-related constructs, such as anxiety sensitivity, illness/injury sensitivity, and fear of negative evaluation have emerged as important to pain.

Identifying experimental methods to determine the effect of pain on attention: a review of pain, caffeine, alcohol and nicotine studies.

Objectives: To review published studies of the effects that pain and common psychopharmacological substances have on the attentional performance of healthy adults. To identify which attentional tasks have the greatest potential to investigate the effect of pain on attention and provide recommendations for future research.

Methods: A search was conducted for reports of experimental studies of attention in the context of pain.

Parenting an adolescent with chronic pain: an investigation of how a taxonomy of adolescent functioning relates to parent distress.

Objective: Cluster analyses allow health professionals to classify adolescents with chronic pain into subgroups, which might allow efficient tailoring of treatment. Given the nature of family relationships when a child has chronic pain, we aimed to evaluate whether an adolescent-disability-derived cluster formula would appropriately classify their parents via parenting stress, anxiety, and depression.

Methods: A patient-report data-derived cluster formula sorted 204 parents of adolescents with chronic pain into 4 groups.

Randomized controlled trials of psychological therapies for management of chronic pain in children and adolescents: an updated meta-analytic review.

The purpose of this meta-analytic review was to quantify the effects of psychological therapies for the management of chronic pain in youth. Specifically, in this review we updated previous systematic reviews of randomized controlled trials by including new trials, and by adding disability and emotional functioning to pain as treatment outcomes. Electronic searches of the Cochrane Register of Randomised Controlled Trials, MEDLINE, PsycLIT, EMBASE, and the Social Sciences Citation Index were conducted from inception through August 2008.

Technologically-assisted behaviour change: a systematic review of studies of novel technologies for the management of chronic illness.

A systematic review was conducted to investigate the use of technology in achieving behaviour change in chronic illness. The areas reviewed were: (1) methods employed to adapt traditional therapy from a face-to-face medium to a computer-assisted platform; (2) targets of behaviour change; and (3) level of human (e.g.

Predicting pain and disability in patients with hand fractures: comparing pain anxiety, anxiety sensitivity and pain catastrophizing.

There is a range of anxiety-related constructs associated with pain and pain-related disability. Those most often examined are pain catastrophizing, pain anxiety and anxiety sensitivity. All three are conceptualized to be important in the development and maintenance of chronic pain, and are included within fear avoidance models.

Expressive dimensions of pain catastrophizing: An observational study in adolescents with chronic pain.

Investigated was the relationship between pain catastrophizing and pain intensity in adolescents suffering from chronic pain (n = 38) and the extent to which they expressed communicative pain and pain-related protective behaviours. Adolescents were observed on video performing a 2-Min Walk Test (2MWT). Behaviours were coded on videotape.

Toward a taxonomy of adolescents with chronic pain: exploratory cluster and discriminant analyses of the bath adolescent pain questionnaire.

Emerging evidence has indicated that adolescent chronic pain is a significant healthcare issue, the impact of which is determined by a complex interplay of biological, emotional, social, and familial factors. Recently, progress has been made in assessment of pain and functioning in adolescents with chronic pain. A next step is to evaluate whether discrete subgroups of patients exist and whether assessment measures can be used to determine subgroup membership for individual pain sufferers.

Acceptance of pain in adolescents with chronic pain: validation of an adapted assessment instrument and preliminary correlation analyses.

It is important to understand the processes that contribute to disability and distress in adolescents with chronic pain. For example, research has identified that when adolescents can positively adapt to the consequences of health condition, rather than attempt to change the condition itself, they also function better and experience less distress. This pattern of behavior is similar to what is referred to as "acceptance" of pain in the adult literature.

The unbearable lightness of somatisation: a systematic review of the concept of somatisation in empirical studies of pain.

Somatisation is often invoked to explain pain and suffering in patients. Lipowski [34] defined somatisation as "a tendency to experience and communicate somatic distress and symptoms unaccounted for by pathological findings, to attribute them to physical illness, and to seek medical help for them" (p. 1359).

Psychological therapies for the management of chronic pain (excluding headache) in adults.

Background: Psychological treatments are designed to treat pain, distress and disability, and are in common practice. No comprehensive systematic review has been published since 1999.

Objectives: To evaluate the effectiveness of psychological therapies on pain, disability, and mood.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents.

Background: Headache, recurrent abdominal pain, and musculoskeletal pain affect many children, who report severe pain, distressed mood, and disability. Psychological therapies are emerging as effective interventions to treat children with chronic or recurrent pain. This is a substantially updated and expanded version of the Cochrane review published in 2003.

Children's catastrophic thinking about their pain predicts pain and disability 6 months later.

Catastrophic thinking about pain has been identified as an important determinant of adjustment to pain, in both adults and children. No study has investigated the prospective and unique role of catastrophizing in explaining later pain and disability in children. The aim of the present study was to investigate the prospective roles of catastrophic thinking about pain, pain intensity, and trait anxiety and their putative relationship with pain and disability tested 6 months later.

Chronic musculoskeletal pain in children: assessment and management.

Paediatricians and paediatric rheumatologists review a large number of children with ongoing pain (disease and non-disease related). A small number of these develop chronic pain conditions that are complex and distressing. Over recent years studies of the epidemiology, aetiology and rehabilitation of pain and pain-associated disability in children have revealed a large prevalence of clinically relevant pain, and have emphasized the need for early recognition and intervention.

Adolescent chronic pain and disability: A review of the current evidence in assessment and treatment.

Adolescents who suffer from chronic pain also report complex syndrome-associated disability and distress that can detrimentally affect the quality of their lives and the lives of their family members. Over the past 10 years, there have been significant developments in both methods of assessment and in treatment programs. There have also been good developments in clinical assessment tools, although many need further study.

Visual impairment following stroke: do stroke patients require vision assessment?

Background: the types of visual impairment followings stroke are wide ranging and encompass low vision, eye movement and visual field abnormalities, and visual perceptual difficulties.

Objective: the purpose of this paper is to present a 1-year data set and identify the types of visual impairment occurring following stroke and their prevalence.

Methods: a multi-centre prospective observation study was undertaken in 14 acute trust hospitals.

The Chronic Pain Acceptance Questionnaire: confirmatory factor analysis and identification of patient subgroups.

Over the past decade, the importance of acceptance of chronic pain has been demonstrated. Acceptance has often been assessed using the 20-item, two-factor Chronic Pain Acceptance Questionnaire (CPAQ; McCracken, Vowles, Eccleston, Pain 2004;107:159-66). This two-factor model has been supported but awaits further confirmation.

Young people making sense of pain: cognitive appraisal, function, and pain in 8-16 year old children.

Recurrent pain is a common childhood problem which for some becomes chronic and is associated with severely impaired functioning. Relationships of psychological variables with impaired functioning have rarely been investigated in samples of children reporting pain in non-clinical settings. The aim of this study was to examine the role of cognitive appraisal in the relationship between chronic pain and level of functioning in a normal school-attending population of children who report pain as a common experience.

Core outcome domains and measures for pediatric acute and chronic/recurrent pain clinical trials: PedIMMPACT recommendations.

Unlabelled: Under the auspices of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT), 26 professionals from academia, governmental agencies, and the pharmaceutical industry participated in a 2-stage Delphi poll and a consensus meeting that identified core outcome domains and measures that should be considered in clinical trials of treatments for acute and chronic pain in children and adolescents. Consensus was refined by consultation with the international pediatric pain community through announcement of our recommendations on the Pediatric Pain List and inviting and incorporating comments from external sources. There was consensus that investigators conducting pediatric acute pain clinical trials should consider assessing outcomes in pain intensity; global judgment of satisfaction with treatment; symptoms and adverse events; physical recovery; emotional response; and economic factors.
