BackgroundPrevalence of pain as a recurrent symptom in children is known to be high, but little is known about children with high impairment from chronic pain seeking specialized treatment. The purpose of this study was the precise description of children with high impairment from chronic pain referred to the German Paediatric Pain Centre over a 5-year period.MethodsDemographic variables, pain characteristics and psychometric measures were assessed at the first evaluation. Subgroup analysis for sex, age and pain location was conducted and multivariate logistic regression applied to identify parameters associated with extremely high impairment.ResultsThe retrospective study consisted of 2249 children assessed at the first evaluation. Tension type headache (48%), migraine (43%) and functional abdominal pain (11%) were the most common diagnoses with a high rate of co-occurrence; 18% had some form of musculoskeletal pain disease. Irrespective of pain location, chronic pain disorder with somatic and psychological factors was diagnosed frequently (43%). 55% of the children suffered from more than one distinct pain diagnosis. Clinically significant depression and general anxiety scores were expressed by 24% and 19% of the patients, respectively. Girls over the age of 13 were more likely to seek tertiary treatment compared to boys. Nearly half of children suffered from daily or constant pain with a mean pain value of 6/10. Extremely high pain-related impairment, operationalized as a comprehensive measure of pain duration, frequency, intensity, pain-related school absence and disability, was associated with older age, multiple locations of pain, increased depression and prior hospital stays. 43% of the children taking analgesics had no indication for pharmacological treatment.ConclusionChildren with chronic pain are a diagnostic and therapeutic challenge as they often have two or more different pain diagnoses, are prone to misuse of analgesics and are severely impaired. They are at increased risk for developmental stagnation. Adequate treatment and referral are essential to interrupt progression of the chronic pain process into adulthood.

ObjectiveThe present study aimed to investigate the effectiveness of a 3-week multimodal inpatient pain program for children and adolescents with chronic pain. MethodsEffectiveness was investigated for pain-related variables (pain intensity, pain-related disability) and emotional distress in 3 ways: (1) in terms of statistically significant changes; (2) in terms of the clinical significance of these changes by creating post-hoc outcome groups for pain-related variables and emotional distress; and (3) in terms of the clinically significant overall amelioration generalizing the outcome over 3 variables (ie, pain intensity, pain-related disability, and school absence). One hundred sixty-seven adolescents (aged between 11 and 18 y) with various pain disorders (50% with headache) who met inpatient criteria were evaluated at baseline and 3 months posttreatment. ResultsPatients demonstrated statistically significant changes in all variables with large to medium effect sizes. Seventy-two percent and 45% of the patients demonstrated clinically significant changes in pain intensity and pain-related disability, respectively. The percentages of patients demonstrating clinically significant change in emotional distress ranged from 13% to 26%. Seventy-seven adolescents demonstrated overall amelioration. DiscussionResults of the study are promising in at least 2 ways: (1) a multimodal inpatient program might stop the negative effects of chronic pain, disability, and emotional distress in children and adolescents, and (2) the exploration of clinical significance testing has demonstrated utility and can be applied to future effectiveness studies in pediatric pain.

&NA; The Quantitative Sensory Testing (QST) protocol of the German research network on neuropathic pain (DFNS) encompassing all somatosensory modalities assesses the functioning of different nerve fibers and of central pathways. The aim of our study was: (1) to explore, whether this QST protocol is feasible for children, (2) to detect distribution properties of QST data and the impact of body site, age and gender and (3) to establish reference values for QST in children and adolescents. The QST protocol of the DFNS with modification of instructions and pain rating was used in 176 children aged 6.12–16.12 years for six body sites. QST was feasible for children over 5 years of age. ANOVAs revealed developmental, gender and body site differences of somatosensory functions similar to adults. The face was more sensitive than the hand and/or foot. Younger children (6–8 years) were generally less sensitive to all thermal and mechanical detection stimuli but more sensitive to all pain stimuli than older (9–12 years) children, whereas there were little differences between older children and adolescents (13–17 years). Girls were more sensitive to thermal detection and pain stimuli, but not to mechanical detection and pain stimuli. Reference values differ from adults, but distribution properties (range, variance, and side differences) were similar and plausible for statistical factors. Our results demonstrate that the full QST protocol is feasible and valid for children over 5 years of age with their own reference values.

Summary Intensive interdisciplinary pain treatment is effective for highly impaired children with chronic pain in terms of the childs well‐being and the economic effects. ABSTRACT Pediatric chronic pain, which can result in deleterious effects for the child, bears the risk of aggravation into adulthood. Intensive interdisciplinary pain treatment (IIPT) might be an effective treatment, given the advantage of consulting with multiple professionals on a daily basis. Evidence for the effectiveness of IIPT is scarce. We investigated the efficacy of an IIPT within a randomized controlled trial by comparing an intervention group (IG) (n = 52) to a waiting‐list control group (WCG) (n = 52). We made assessments before treatment (PRE), immediately after treatment (POST), as well as at short‐term (POST6MONTHS) and long‐term (POST12MONTHS) follow‐up. We determined a combined endpoint, improvement (pain intensity, disability, school absence), and investigated 3 additional outcome domains (anxiety, depression, catastrophizing). We also investigated changes in economic parameters (health care use, parental work absenteeism, subjective financial burden) and their relationship to the childs improvement. Results at POST showed that significantly more children in the IG than in the WCG were assigned to improvement (55% compared to 14%; Fisher P < .001; 95% confidence interval for incidence difference: 0.21% to 0.60%). Although immediate effects were achieved for disability, school absence, depression, and catastrophizing, pain intensity and anxiety did not change until short‐term follow‐up. More than 60% of the children in both groups were improved long‐term. The parents reported significant reductions in all economic parameters. The results from the present study support the efficacy of the IIPT. Future research is warranted to investigate differences in treatment response and to understand the changes in economic parameters in nonimproved children.

BACKGROUND AND OBJECTIVE: Pediatric debilitating chronic pain is a severe health problem, often requiring complex interventions such as intensive interdisciplinary pain treatment (IIPT). Research is lacking regarding the effectiveness of IIPT for children. The objective was to systematically review studies evaluating the effects of IIPT. METHODS: Cochrane, Medline/Ovid, PsycInfo/OVID, PubMed, PubPsych, and Web of Science were searched. Studies were included if (1) treatment was coordinated by ≥3 health professionals, (2) treatment occurred within an inpatient/day hospital setting, (3) patients were <22 years, (4) patients experienced debilitating chronic pain, (5) the study was published in English, and (6) the study had ≥10 participants at posttreatment. The child’s pain condition, characteristics of the IIPT, and 5 outcome domains (pain intensity, disability, school functioning, anxiety, depressive symptoms) were extracted at baseline, posttreatment, and follow-up. RESULTS: One randomized controlled trial and 9 nonrandomized treatment studies were identified and a meta-analysis was conducted separately on pain intensity, disability, and depressive symptoms revealing positive treatment effects. At posttreatment, there were large improvements for disability, and small to moderate improvements for pain intensity and depressive symptoms. The positive effects were maintained at short-term follow-up. Findings demonstrated extreme heterogeneity. CONCLUSIONS: Effects in nonrandomized treatment studies cannot be attributed to IIPT alone. Because of substantial heterogeneity in measures for school functioning and anxiety, meta-analyses could not be computed. There is preliminary evidence for positive treatment effects of IIPT, but the small number of studies and their methodological weaknesses suggest a need for more research on IIPTs for children.

Preliminary evidence suggests that parental catastrophizing about their childs pain may be important in understanding both parental responses to their childs pain and the childs pain experience. However, little is known about potential differences between mothers and fathers. There were three aims of the present study addressing this lack of knowledge: (i) to investigate the three‐factor structure of the German version of the Parental Pain Catastrophizing Scale (PCS‐P) ( Goubert et al., 2006 ) in mothers and fathers of children with chronic pain, (ii) to explore differences between mothers and fathers in parental catastrophizing, (iii) to investigate the contribution of parental catastrophizing on the childs chronic pain problem and pain‐related parent behavior.

ZusammenfassungHintergrundAls Folge chronischer Schmerzen leiden viele Kinder und Jugendliche unter schmerzbedingten Beeinträchtigungen, die sich auf alle Lebensbereiche auswirken können. Ein zentrales Ziel der Kinderschmerztherapie ist die Reduktion dieser schmerzbedingten Beeinträchtigungen, allerdings fehlen bisher geeignete validierte Messinstrumente. Ziel dieser Untersuchung ist die Übersetzung des Pediatric Pain Disability Index (P-PDI) von Varni und die Überprüfung seiner psychometrischen Eigenschaften.MethodenBei 163 ambulant und 167 stationär behandelten Jugendlichen mit chronischen Schmerzen (vorwiegend Kopfschmerzen) wurden Hauptkomponenten- und Itemanalysen durchgeführt. Zur Überprüfung der Stabilität wurde die Veränderung der schmerzbedingten Beeinträchtigung 3 Monate nach Beginn der ambulanten Therapie bei 110 Jugendlichen untersucht. Zudem wurden der Zusammenhang der schmerzbedingten Beeinträchtigung mit Schmerzvariablen, emotionaler Beeinträchtigung und Schulfehltagen und die Übereinstimmung zwischen Selbst- und Elterneinschätzung überprüft.ErgebnisseDer P-PDI zeigt sich als eindimensionales Messinstrument mit zufrieden stellender Reliabilität. Signifikante Zusammenhänge konnten zwischen der schmerzbedingten Beeinträchtigung und Schmerzintensität sowie Schulfehltagen aufgezeigt werden; kein Zusammenhang fand sich zu Schmerzdauer, Angst und Depression. Eltern- und Selbsteinschätzung korrelieren signifikant, jedoch schätzen 57% der Eltern die schmerzbedingte Beeinträchtigung ihrer Kinder niedriger ein als diese selbst.SchlussfolgerungMit dem P-PDI liegt erstmals ein validiertes deutschsprachiges Instrument zur Einschätzung der schmerzbedingten Beeinträchtigung bei Jugendlichen mit chronischen Schmerzen vor, das gut zur Überprüfung von Therapieeffekten genutzt werden kann.AbstractBackgroundPain-related disability affects many children and adolescents suffering from chronic pain and may exert an impact on all areas of their lives. Reduction of pain-related disability is, therefore, a fundamental aim of treatment; however, no validated means exist to assess pain-related disability in children and adolescents. The aim of this study was to translate the Pediatric Pain Disability Index (P-PDI) of Varni into German and to investigate its psychometric qualities.MethodsPrincipal component and item analyses were conducted on outpatient (n=163) and inpatient samples (n=167) of adolescents suffering from chronic pain. Changes in pain-related disability 3 months after starting treatment were analysed in an outpatient sample of 110 adolescents. Correlations between pain-related disability, emotional variables and school absence as well as concordance with parents’ ratings were investigated.ResultsThe P-PDI is a one-dimensional assessment tool with sufficient reliability. There were significant correlations between pain-related disability and pain intensity and school absence but not with pain duration, fear and depression. Parents and adolescents ratings correlated significantly, but 57% of parents underestimated the pain-related disability of their children.ConclusionThere is now a validated German version of the P-PDI to measure pain-related disability in adolescents suffering from chronic pain, which can be used in studies investigating treatment effectiveness.

UNLABELLED While sex differences in pain-related coping have been widely reported, little is known on sex differences in changes in coping following multimodal pain treatment and how these changes relate to treatment outcome. The present prospective study therefore aimed to investigate sex differences in coping strategies between boys and girls with chronic pain prior to multimodal inpatient treatment and at 3-month follow-up. Sixty-four boys and 103 girls with various pain disorders were evaluated. Core outcomes (pain intensity and pain-related disability) and coping were assessed via validated questionnaires. At admission, boys and girls used similar coping strategies. Three months following treatment, boys and girls decreased passive pain coping and seeking social support while they maintained the degree of positive self-instruction. Girls displayed higher seeking social support than boys and of importance, only for girls, a reduction in seeking social support was related to decreases in pain intensity. In both groups, the changes in coping were related to positive treatment outcome. Results suggest that both groups may benefit from reductions in passive pain coping and seeking social support. The causal quality of this relationship remains to be determined in future studies. Gender-role expectations and family interactions may account for the sex differences demonstrated for seeking social support. PERSPECTIVE Boys and girls with chronic pain show profound similarities in pain-related coping strategies prior and after multimodal pain treatment. The changes in coping are related to positive treatment outcomes. Sex-specific treatment strategies for changing seeking social support may need to be developed and tested for their differential efficacy in boys and girls.

The effects of a physical exercise session on state body image and mood were examined. In a cross-over design, participants were randomised to two groups starting either with physical exercise (PE; experimental condition) or with reading a newspaper (RN; control condition). Before and after PE and RN, participants (N = 65) rated their body dimensions using a digital photo distortion technique and indicated their attitudinal body image and mood. Participants’ judgements of their ‘felt’ body dimensions and attitudes toward their own body were affected differently by PE and RN, indicating that participants felt slightly slimmer and were more satisfied with their bodies after PE. Exercise-induced changes in body perception were greater, the higher the pre-experimental drive for thinness, body dissatisfaction and weight/shape concerns were. Especially in those participants with higher body image disturbances, physical exercise can have a reinforcing effect on immediate body image and mood improvement.
