Development and Preliminary Testing of a Scale to Assess Pain-Related Fear in Children and Adolescents

Measurement properties and feasibility of chronic pain assessment tools for use with children and young people with cerebral palsy

PURPOSE

Chronic pain assessment tools exist for children, but may not be valid, reliable, and feasible for populations with functional, cognitive or communication limitations, for example, cerebral palsy (CP). This study aimed to (i) identify chronic pain assessment tools used with children and young people and rate their measurement properties; (ii) develop a CP specific feasibility rating tool to assess the feasibility of tools in CP; and (iii) categorise tools according to reporting method.

MATERIALS AND METHODS

Assessment tools were identified by literature review. Their measurement properties were rated using the COnsensus based standards for the Selection of health Measurement INstruments. The CP specific Feasibility Rating Tool was developed and used to rate the tools.

RESULTS

Fifty-seven chronic pain assessment tools were identified. Six have content validity for CP, four of these use proxy-report. Forty-two tools were considered feasible for people with CP; 24 self report and 18 observational/proxy-report. Only the Paediatric Pain Profile has content validity and feasibility for people with CP unable to self-report.

CONCLUSIONS

There are few valid, reliable and feasible tools to assess chronic pain in CP. Further research is required to modify tools to enable people with cognitive limitations and/or complex communication to self-report pain.

Mother– and Father–Child Reminiscing About Past Events Involving Pain, Fear, and Sadness: Observational Cohort Study

Objective

Pain in childhood is prevalent and is associated with fear, particularly in the context of injuries or procedural pain, and negative emotions (e.g., sadness). Pain and fear share a bidirectional relationship, wherein fear exacerbates the experience of pain and pain increases subsequent anticipatory fear. The existing research has focused primarily on children’s immediate experience of pain and fear. Research on how children remember or talk about past painful, fearful, or sad events is lacking. Parent–child reminiscing about past pain has been demonstrated to differ from reminiscing about other past negative emotional events (i.e., those involving sadness, but not fear). The present study aimed to examine differences in how parent–child dyads reminisce about past pain, fear, and sadness.

Methods

One hundred and three 4-year-old children (55% girls) and their parents (52% fathers) engaged in a narrative elicitation task in which they reminisced about unique past events involving pain, fear, and sadness. Parent–child narratives were coded using established coding schemes based on the developmental psychology literature.

Results

Parent–child narratives about pain were characterized by fewer emotion-laden words and explanations, as well as more pain-related words compared to sadness or fearful narratives. Mothers and fathers reminisced with sons and daughters in a similar way across all types of events.

Conclusions

Parent–children reminiscing about past painful events differs from reminiscing about other types of distressing events (e.g., involving sadness or fear). This highlights a possibility of differential socialization of pain versus fear. Potential clinical implications of the findings are discussed.

Use of Virtual Reality Distraction to Reduce Child Pain and Fear during Painful Medical Procedures in Children with Physical Disabilities in Uganda: A feasibility study

OBJECTIVE

This study explored the acceptability and feasibility of the use of low-cost virtual reality (VR) glasses, and the Wong-Baker Faces Pain Scale and Children's Fear Scale scales, for pain and fear reduction in children admitted at the septic ward of CoRSU Rehabilitation Hospital in Uganda.

METHODS

In total 79 children aged 4 to 17 years of age were offered to watch cartoons using VR glasses while undergoing painful dressing procedures. Before and after the procedure children were asked to index current pain; children and their caregivers were asked to rate anticipated fear. Focus group discussions with 13 children, 10 caregivers and 9 nurses explored acceptability and feasibility. Quantitative data were analysed using STATA15, NVIVO12 was used for qualitative data analysis.

RESULTS

The VR glasses were accepted by 76 (96%) of the children. Children, caregivers, and nurses mentioned the glasses were helpful in distracting children from the medical procedure, and felt the use of the glasses helped reduce child fear and pain. Nurses felt it made their work easier. The Wong-Baker Faces Pain Scale was an acceptable and feasible method to measure pain, whilst the Children's Fear Scale was more difficult to interpret for our study population as they felt the faces on the scale were hard to read and identify with.

CONCLUSIONS

The use of VR glasses may offer an acceptable and effective pain and fear reduction method in resource-constrained settings and should be further explored in a randomized controlled trial.

A Network Analysis of Potential Antecedents and Consequences of Pain-Related Activity Avoidance and Activity Engagement in Adolescents

OBJECTIVE

This study sets out to identify potential daily antecedents and consequences of pain-related activity avoidance and engagement behavior in adolescents with chronic pain.

METHODS

Adolescents (N = 65, Mage = 14.41) completed baseline self-reports and a diary for 14 days. Afternoon and evening reports were used to infer a network structure of within-day associations between pain intensity, pain-related fear, pain catastrophizing, affect, and pain-related activity avoidance and engagement behavior. Baseline psychological flexibility was examined as a potential resilience factor.

RESULTS

Activity avoidance in the evening was predicted by pain-related fear and avoidance earlier that afternoon. Activity engagement was predicted by positive affect and activity engagement in the afternoon. Pain-related behavior in the afternoon was not related to subsequent changes in pain intensity, pain-related fear, pain catastrophizing, or affect. Pain-related fear in the afternoon was predictive of increased levels of pain and pain catastrophizing in the evening. Both pain-related fear and pain catastrophizing in the evening were predicted by negative affect in the afternoon. Psychological flexibility was associated with lower levels of daily activity avoidance and buffered the negative association between pain intensity and subsequent activity engagement.

CONCLUSIONS

This study provides insight into unique factors that trigger and maintain activity avoidance and engagement and into the role of psychological flexibility in pediatric pain. Future work should focus on both risk and resilience factors and examine the role of psychological flexibility in chronic pediatric pain in greater detail.

Age and pain score before gastrointestinal endoscopies in children are predictors for post procedure pain

Background

Gastrointestinal endoscopy may be associated with pain and anxiety. Predictors for high pain scores after endoscopies in children are not known. The aim of our study was to identify risk factors for prolonged recovery and higher pain scores after gastrointestinal endoscopy in children.

Methods

All the children that were electively admitted for gastrointestinal endoscopies were included. We retrospectively collected demographic, clinical and endoscopic data as well as information on the recovery process. A numerical rating scale and the Faces, Legs, Activity, Cry, and Consolability Scale were used for pain scoring.

Results

During the study period (01/2016–10/2016), 284 children (median age 10.7 years, interquartile range 6.7–14.8) were recruited. In a univariate analysis, older age, higher pre-procedure pain scores, longer procedure durations, higher number of biopsies and longer recovery duration were associated with higher post-procedure pain scores. In a multivariate analysis higher pain scores before the procedure (OR 12.42, 95% CI 3.67–42, P < 0.001) and older age (OR 1.016, 95% CI 1.007–1.025, P < 0.001) were associated with higher pain scores after the procedure. Children with a higher pain score before the procedure also had a longer recovery period (OR 5.28, 95% CI (1.93–14.49), P = 0.001).

Conclusion

Older age and higher pain score before the procedure were identified as predictors for higher pain score after pediatric gastrointestinal endoscopies. Children with these risk factors should be identified before the procedure in order to personalize their post-procedure management.

CE: Assessing a Child's Pain

: Effective pain assessment is a necessary component of successful pain management and the pursuit of optimal health outcomes for patients of all ages. In the case of children, accurate pain assessment is particularly important, because children exposed to prolonged or repeated acute pain, including procedural pain, are at elevated risk for such adverse outcomes as subsequent medical traumatic stress, more intense response to subsequent pain, and development of chronic pain.As with adults, a child's self-report of pain is considered the most accurate and reliable measure of pain. But the assessment of pain in children is challenging, because presentation is influenced by developmental factors, and children's responses to certain features of pain assessment tools are unlike those commonly observed in adults.The authors describe the three types of assessment used to measure pain intensity in children and the tools developed to address the unique needs of children that employ each. Such tools take into account the child's age as well as special circumstances or conditions, such as ventilation requirements, cognitive impairment, and developmental delay. The authors also discuss the importance of proxy pain reporting by the parent or caregiver and how nurses can improve communication between the child, caregiver, and health care providers, thereby promoting favorable patient outcomes.

The Tampa Scale of Kinesiophobia: Structural Validation among Adolescents with Idiopathic Scoliosis Undergoing Spinal Fusion Surgery

AIMS

Spinal fusion surgery is one of the most invasive orthopedic surgeries. Pain while moving or a fear of experiencing pain after surgery may delay return to function and cause prolonged disability. The purpose of the study was to examine the psychometric properties of the Tampa Scale of Kinesiophobia (TSK) in pediatric patients undergoing scoliosis surgery.

METHODS

Fifty-five adolescents (10-18 years old) scheduled for spinal fusion surgery were enrolled. Participants completed the TSK questionnaire before surgery and six weeks after surgery. Reliability, exploratory and confirmatory factor analyses were performed on the two-factors TSK including activity avoidance (TSK-AA) and somatic focus (TSK-SF).

RESULTS

Before and after surgery, all TSK-AA items conformed into the same factor component and revealed good internal reliability with Cronbach's alpha of .76 and .70 respectively. TSK-SF items were separated into different factor components and revealed poor reliability (.11 and .56). The TSK-AA also produced an adequate fit to the data, as reflected with several fit indices at both timepoints, respectively: χ²/df = 1.19 and 1.22; CFI=.96 and .94; and RMSEA=.06 and .06.

CONCLUSIONS

The TSK-AA demonstrated good psychometric properties in patients undergoing scoliosis surgery, which provides empirical evidence for pediatrics. Its validation in distinct populations and settings is recommended prior to its use.

Children's self-reports of fear and pain levels during needle procedures

Aim

The objective was to determine the levels of and potential relationships between, procedure-related fear and pain in children.

Design

Clinical based cross-sectional.

Methods

Ninety children aged between 7-18 years were included consecutively and self-reported levels of pain and fear on a 0-100 mm visual analogue scales (VAS) when undergoing routine needle insertion into a subcutaneously implanted intravenous port following topical anaesthesia.

Results

The needle-related fear level was reported to be as high as the needle-related pain level (mean VAS: 14 mm and 12 mm, respectively, N = 90). With fear as the dependent variable, age and pain were significantly associated and explained 16% of the variance. With pain as the dependent variable, fear was significantly associated and explained 11% of the variance. A post hoc analysis indicated that younger children reported their fear levels to be higher than their pain levels.

Efficacy of adding interoceptive exposure to intensive interdisciplinary treatment for adolescents with chronic pain: a randomized controlled trial

Fear of pain plays an important role in the maintenance of chronic pain. It may be reduced through exposure therapy. This 2-arm parallel samples randomized controlled trial aimed to investigate whether interoceptive exposure (IE) therapy enhances reductions in fear of pain (primary outcome), pain (pain intensity, pain-related disability, and school absence), and emotional characteristics (anxiety and catastrophizing) when implemented as an adjunctive treatment in the context of intensive interdisciplinary pain treatment for pediatric chronic pain patients. N = 126 adolescents, aged 11 to 17 years, who were receiving standard intensive interdisciplinary pain treatment were randomly assigned to either receive additional IE (n = 64) or additional relaxation therapy (RT) (n = 62). All patients were assessed at admission, discharge, and 3 months after discharge. The data of N = 104 patients were analyzed. Significant large reductions were found in the total score and subscale scores of the Fear of Pain Questionnaire for Children in both study groups (eg, total score [range 0-60; IE/RT]: admission M = 23.5/24.9; discharge M = 16.0/19.7; P < 0.001, (Equation is included in full-text article.)= 0.27) and mainly large reductions in pain characteristics. There were no greater decreases in the IE group (P > 0.1). The exploratory analyses revealed that the patients with high fear of pain before treatment (P < 0.05, (Equation is included in full-text article.)> 0.03) and the patients with abdominal pain (P < 0.04, (Equation is included in full-text article.)> 0.25) showed greater decreases in their fear of pain (total and subscale score) in the IE group than in the RT group. In conclusion, the results suggest that IE is not particularly effective for all the pediatric chronic pain patients, but the patients with high fear of pain before treatment and with abdominal pain strongly benefit from this intervention.

Assessment of Pain Anxiety, Pain Catastrophizing, and Fear of Pain in Children and Adolescents With Chronic Pain: A Systematic Review and Meta-Analysis

Objective

To conduct a systematic review of pain anxiety, pain catastrophizing, and fear of pain measures psychometrically established in youth with chronic pain. The review addresses three specific aims: (1) to identify measures used in youth with chronic pain, summarizing their content, psychometric properties, and use; (2) to use evidence-based assessment criteria to rate each measure according to the Society of Pediatric Psychology (SPP) guidelines; (3) to pool data across studies for meta-analysis of shared variance in psychometric performance in relation to the primary outcomes of pain intensity, disability, generalized anxiety, and depression.

Methods

We searched Medline, Embase, PsycINFO, and relevant literature for possible studies to include. We identified measures studied in youth with chronic pain that assessed pain anxiety, pain catastrophizing, or fear of pain and extracted the item-level content. Study and participant characteristics, and correlation data were extracted for summary and meta-analysis, and measures were rated using the SPP evidence-based assessment criteria.

Results

Fifty-four studies (84 papers) met the inclusion criteria, including seven relevant measures: one assessed pain anxiety, three pain catastrophizing, and three fear of pain. Overall, five measures were rated as "well established." We conducted meta-analyses on four measures with available data. We found significant positive correlations with the variables pain intensity, disability, generalized anxiety, and depression.

Conclusion

Seven measures are available to assess pain anxiety, pain catastrophizing, and fear of pain in young people with chronic pain, and most are well established. We present implications for practice and directions for future research.

Comparison of Children's Venipuncture Fear and Pain: Randomized Controlled Trial of EMLA® and J-Tip Needleless Injection System®

PURPOSE

Needle procedures, like venipuncture and intravenous (IV) catheter insertion, are recognized as a common cause of pain and fear for children in hospitals and emergency departments. The purpose of this study was to compare children's self-reported pain and fear related to IV insertion with administration of either the topical local anesthetic EMLA® or 1% buffered lidocaine delivered with the J-Tip Needleless Injection System® (J-Tip®).

DESIGN AND METHODS

In this prospective, randomized trial, 150 consecutive pediatric patients 8 to 18years of age undergoing IV insertion were randomly assigned 1:1 to treatment group. Participants self-reported procedural pain using a Visual Analog Scale, and procedural fear using the Children's Fear Scale.

RESULTS

Procedural pain scores were significantly lower in the EMLA® group (mean score 1.63+1.659) vs. the J-Tip® group (2.99±2.586; p<0.001). Post-procedure fear scores were significantly lower than pre-procedure fear scores in both treatment groups (p<0.002), but there was no difference in fear scores between the two treatment groups (p=0.314).

CONCLUSION

EMLA® provided superior pain relief for IV insertion compared to J-Tip®.

PRACTICE IMPLICATIONS

Although EMLA® use resulted in lower self-reported pain scores compared to J-Tip®, pain scores for both treatments were low and fear scores did not differ. When IV insertion can be delayed for 60-90min, EMLA® should be used. When a delay is contraindicated, J-Tip® may be a reasonable alternative to minimize procedural pain of IV insertion.

Dutch version of the Fear of Pain Questionnaire for adolescents with chronic pain

BACKGROUND

Fear of pain is important in the development and maintenance of chronic pain. The Fear of Pain Questionnaire-Child version has been developed to assess pain related fear in children and adolescents.

OBJECTIVE

Translating the original questionnaire into Dutch, and investigating internal consistency and construct validity to enable use in the Dutch pain rehabilitation setting for treatment and research.

METHODS

Cross-sectional validation study: After forward and back translation of the FOPQ-C, adolescents (11-22 years old) with chronic musculoskeletal pain completed an assessment containing the Dutch Fear of Pain Questionnaire, and questionnaires about demographics, pain catastrophizing, functional disability, and pain intensity. Internal consistency and construct validity were evaluated through exploratory factor analysis (principal axis factoring with oblique rotation) and hypotheses testing using pain catastrophizing, functional disability, and pain intensity as comparative constructs.

RESULTS

Eighty-six adolescents completed the assessment. Exploratory factor analysis resulted in a two-factor structure, explaining 43% of the variance. Internal consistency was strong (Cronbach's α = 0.92 total scale, α = 0.88 factor 1, and α = .86 factor 2). Five out of 6 hypotheses were confirmed.

CONCLUSIONS

The Dutch version demonstrated good internal consistency and good construct validity in a population of adolescents with chronic musculoskeletal pain. Implications for rehabilitation The Fear of Pain Questionnaire-Child version was developed to measure fear of pain and avoidance in children and adolescents with chronic pain. Identification of fear of pain and activities that are being avoided are important during screening and assessment of the adolescent for chronic pain rehabilitation treatment. The presence of fear of pain and/or avoidance behavior is important information to shape and target multidisciplinary rehabilitation treatment.

Fear of pain in children and adolescents with neuropathic pain and complex regional pain syndrome

A significant proportion of children and adolescents with chronic pain endorse elevated pain-related fear. Pain-related fear is associated with high levels of disability, depressive symptoms, and school impairment. Because of faulty nerve signaling, individuals with neuropathic pain and complex regional pain syndrome may be more prone to develop pain-related fear as they avoid use of and neglect the affected body area(s), resulting in exacerbated symptoms, muscle atrophy, maintenance of pain signaling, and ongoing pain-related disability. Not surprisingly, effective treatments for elevated pain-related fears involve exposure to previously avoided activities to downregulate incorrect pain signaling. In the context of intensive interdisciplinary pain treatment of youth with neuropathic pain, decreasing pain-related fear is associated with improved physical and psychological functioning, whereas high initial pain-related fear is a risk factor for less treatment responsiveness. An innovative approach to targeting pain-related fear and evidence of a neural response to treatment involving decoupling of the amygdala with key fear circuits in youth with complex regional pain syndrome suggest breakthroughs in our ability to ameliorate these issues.

Management of acute pediatric pain in the emergency department

PURPOSE OF REVIEW

This article provides a summary of recommendations for the multimodal and multidisciplinary approach to acute pediatric pain management and highlights recent research on this topic.

RECENT FINDINGS

Recent literature has focused on updating recommendations for the use of various analgesics in the pediatric population. While codeine is no longer recommended due to increasing evidence of adverse effects, the more liberal use of intranasal fentanyl is now encouraged because of the ease of administration and rapid delivery. The evidence base for the use of ultrasound-guided regional nerve blocks by qualified providers in the acute pediatric pain setting continues to grow.

SUMMARY

The pediatric emergency medicine provider should be able to assess pain and develop individualized pain plans by utilizing a range of nonpharmacologic and pharmacologic strategies. Knowledge of the most recent literature and changes in recommendations for various pain medications is essential.

Validation of three pain scales among adult postoperative patients in Ghana

BACKGROUND

Pain assessment is an important component of pain management and health professionals require valid tools to assess pain to guide their pain management decisions. The study sought to select, develop, and validate context-appropriate unidimensional pain scales for pain assessment among adult post-operative patients.

METHODS

A mixed methods design was adopted. The study was conducted at two hospitals in Accra, Ghana. The qualitative phase involved 17 patients and 25 nurses, and the quantitative phase involved 150 post-operative patients. Qualitative data was collected iteratively through individual interviews and focus groups.

RESULTS

Two existing pain scales (0-10 Numeric Rating Scale [NRS] and Wong-Baker FACES [FPS] scales) and one new pain scale (Colour-Circle Pain Scale-[CCPS]) were validated. The psychometric properties of the three scales were assessed when patients had fully recovered from anesthesia. The CCPS had higher scale preference than NRS and FPS. Convergent validity was very good and significant (0.70-0.75). Inter-rater reliability was high (0.923-0.928) and all the scales were sensitive to change in the intensity or level of pain experienced before and after analgesia such as paracetamol and diclofenac suppositories, injectable pethidine, and oral tramadol had been administered.

CONCLUSION

Using a valid tool for pain assessment gives the clinician an objective criterion for pain management. Due to the subjective nature of pain, consideration of socio-cultural factors for the particular context ensures that the appropriate tool is used.

The psychometric characteristics of an assessment instrument for perceived harmfulness in adolescents with musculoskeletal pain (PHODA-youth)

BACKGROUND

Cognitive-behavioural models of chronic pain predict that dysfunctional assumptions about harmfulness of activities may maintain pain-related fear and disability. To assess perceived harmfulness in adolescents, the Photograph Series of Daily Activities for youth (PHODA-youth) was developed. Information concerning its methodological quality is currently lacking.

OBJECTIVE

To investigate psychometric characteristics (factor structure, test-retest reliability, construct validity) and feasibility of the PHODA-youth in adolescents with chronic musculoskeletal pain.

STUDY DESIGN

Test-retest design.

STUDY POPULATION

Adolescents aged 13-21 years with chronic nonspecific musculoskeletal pain.

METHODS

Participants filled in an electronic version of the PHODA-youth including 89 items twice with a 4-week interval. The instrument's factor structure was determined by a factor analysis. Construct validity was studied with criterion variables: catastrophizing (Pain Catastrophizing Scale for Children), pain intensity (visual analogue scale), depression (Children's Depression Inventory) and pain-related disability (Functional Disability Inventory) using regression analysis. Test-retest reliability was evaluated based on the Pearson correlation coefficient. Feasibility was studied with self-constructed questions.

RESULTS

Seventy-one adolescents participated. Results show a three-factor structure for the PHODA-youth including 51 items with subscales labelled as: 'activities of daily life', 'intensive physical activities' and 'social activities'. Total and subscale scores showed a high internal consistency. Its test-retest reliability was good (r = 0.94) and its construct validity is supported by the finding that both catastrophizing (β = 0.25; p = 0.02) and disability (β = 0.71; p < 0.001) were uniquely related to the PHODA-youth. In addition, feasibility appeared adequate.

CONCLUSION

The findings support the PHODA-youth as a valid and reliable measure of the perceived harmfulness of activities in adolescents with musculoskeletal pain.

Pediatric fear-avoidance model of chronic pain: foundation, application and future directions

The fear-avoidance model of chronic musculoskeletal pain has become an increasingly popular conceptualization of the processes and mechanisms through which acute pain can become chronic. Despite rapidly growing interest and research regarding the influence of fear-avoidance constructs on pain-related disability in children and adolescents, there have been no amendments to the model to account for unique aspects of pediatric chronic pain. A comprehensive understanding of the role of fear-avoidance in pediatric chronic pain necessitates understanding of both child⁄adolescent and parent factors implicated in its development and maintenance. The primary purpose of the present article is to propose an empirically-based pediatric fear-avoidance model of chronic pain that accounts for both child⁄adolescent and parent factors as well as their potential interactive effects. To accomplish this goal, the present article will define important fear-avoidance constructs, provide a summary of the general fear-avoidance model and review the growing empirical literature regarding the role of fear-avoidance constructs in pediatric chronic pain. Assessment and treatment options for children with chronic pain will also be described in the context of the proposed pediatric fear-avoidance model of chronic pain. Finally, avenues for future investigation will be proposed.

Pain is not over when the needle ends: a review and preliminary model of acute pain memory development in childhood

SUMMARY Over the past several decades, the field of pediatric pain has made impressive advances in our understanding of the pain experience of the developing child, as well as the devastating impact of inadequately managed pain early in life. It is now well recognized that, from infancy, children are capable of developing implicit memories of pain that can influence their subsequent reactions to pain. The present review provides a synthesis of selected studies that made a significant impact on this field of inquiry, with particular emphasis on recent clinical and laboratory-based experimental research examining children’s explicit autobiographical memories for acute pain. Research has begun to move towards improving the precision with which children at risk for developing negatively estimated pain memories can be identified, given the adverse influence these memories can have on subsequent pain experiences. As such, several fear- and anxiety-related child and parent variables implicated in this process are discussed, and avenues for future research and clinical intervention are identified throughout. Finally, a preliminary empirically and theoretically derived model of acute pain memory development in childhood is presented to parsimoniously summarize the evidence accumulated to date and guide future investigation in this area.

Managing procedural pain in pediatric patients

PURPOSE OF REVIEW

To review recent research on the management of acute procedural pain in pediatric patients.

RECENT FINDINGS

Pediatric patients experience pain with the same or greater intensity as their adult counterparts. Recent studies have acknowledged the importance of people's beliefs about pain and of a multidisciplinary approach to the assessment and treatment of acute pain.

SUMMARY

Pediatric patients experience pain from procedures related to their care. Pediatricians should educate themselves regarding the accurate assessment of pain, and the pharmacologic and nonpharmacologic methods of managing acute pain.

The influence of parent preprocedural anxiety on child procedural pain: mediation by child procedural anxiety

OBJECTIVE

Data suggest parents' preprocedural anxiety is related to children's acute procedural anxiety and pain. This study examined the temporal relations among these constructs to determine whether children's anxiety mediates the relation between parents' anticipatory anxiety and children's procedural pain.

METHODS

A total of 90 preschoolers receiving immunizations, their parents, and the nurses rated children's procedural anxiety and pain. Parents provided ratings of their own preprocedural anxiety.

RESULTS

Bootstrapping analyses revealed that children's procedural anxiety mediated the relation between parents' preprocedural anxiety and children's procedural pain according to parents' report and nurses' report but not children's self-report of anxiety and pain.

CONCLUSIONS

Analyses suggest that children's procedural anxiety mediates the relation between parents' anticipatory anxiety and children's procedural pain. Thus, targeting parents' preprocedural anxiety might be beneficial to the parents as well as the children undergoing a distressing medical procedure.

Psychological interventions for headache in children and adolescents

Headache in children and adolescents represents a number of complex and multifaceted pain syndromes that can benefit from psychological intervention. There is good evidence for the efficacy of cognitive behavioral therapy, relaxation training, and biofeedback. The choice of intervention is influenced by patients' age, sex, family and cultural background, as well as the nature of stressors and comorbid psychiatric symptoms. Management must always be family-centered. Psychological treatments are essential elements of the multidisciplinary, biopsychosocial management of primary headache disorders, particularly for those with frequent or chronic headache, a high level of headache-related disability, medication overuse, or comorbid psychiatric symptoms. Future studies of efficacy and effectiveness of psychological treatment should use the International Headache Society's definition and classification of headache disorders, and stratify results by headache type, associated conditions, and treatment modality.
