Assessing the experience and impact of pain in adolescents with chronic pain is necessary to guide both individual treatment and to inform treatment development. Ideally, to obtain a comprehensive understanding of the impact of pain, assessment should be multidimensional, should be sensitive to contextual variables, and should allow for multiple informants (in particular, parents). The purpose of this study was to develop a standardized parent-report measure of chronic pain in adolescents, the Bath Adolescent Pain Questionnaire - Parent report (BAPQ-P). ⋯ Validity was examined in relation to existing validated child report measures of anxiety, depression, catastrophizing, disability, family, and social functioning and parent report measures of disability and family functioning. Psychometric evaluation suggests that the BAPQ-P is a reliable and valid parental report tool for assessing the multidimensional impact of adolescent chronic pain. It can be used in conjunction with the previously established adolescent self-report measure, the BAPQ, alone where adolescent self report is not possible, in studies where parent report is the focus, or in studies where concordance between parent and adolescent reports is of interest.

Complex regional pain syndromes (CRPS) have been recognized with increasing frequency in children. These disorders appear to differ markedly from those observed in adults. The International Association for the Study of Pain diagnostic criteria for CRPS were developed based on adult studies; these criteria have not been validated for children. ⋯ There was a significant correlation between mechanical dynamic allodynia and allodynia to punctate temporal summation (P<0.001). As with adult CRPS, the thermal and mechanical sensory abnormalities appear in different combinations in different patients with similar clinical presentations. In a majority of patients, the pathogenesis of pain is seemingly of central origin.

Understanding a change score is indispensable for interpretation of results from clinical studies. One way of determining the relevance of change scores is through the use of transition questions that assesses patients' retrospective perception of treatment effect. Unfortunately, results from studies using transition questions are difficult to compare since wording of questions and definitions of important improvements vary between studies. ⋯ Results demonstrated small variations in ROC(auc) across the external criteria for all outcome measures. 7% more patients were classified as improved in the group receiving the 15-point TQ compared to the 7-point TQ (stringent standard). SRMs were higher for the retrospective TQs in primary sector patients compared to the serial measures with no difference between TQ1 and TQ2. On the basis of our findings we have outlined a proposal for a standardised use of transition questions.

An increasing number of studies consider the specific processes by which distressing sensations, thoughts, and emotional experiences exert their influence on the daily functioning of those who suffer with chronic pain. Clinical methods of mindfulness and the processes that underlie them appear to have clear implications in this area, but have not been systematically investigated to this point in time. The purpose of the present study was to examine mindfulness in relation to the pain, emotional, physical, and social functioning of individuals with chronic pain. ⋯ In each instance greater mindfulness was associated with better functioning. The combined increments of variance explained from acceptance of pain and mindfulness were at least moderate and, in some cases, appeared potentially meaningful. The behavioral processes of mindfulness and their accessibility to scientific study are considered.

Pain is an experience including physiological and psychological factors. We assume that emotions may be elicited and increased through self-perceived role identity and that change of role identity alters quality and intensity of pain perception. We used role-play strategies to assess whether pain can be better tolerated whenever, in an unavoidable and unpleasant context, role identity confers pain a meaningful and thus suitable character. ⋯ Women showed higher pain ratings. Hence, self-perception influences pain perception. Role-play strategies may be of value for new pain management strategies.
