Maternal Anxiety and Children's Laboratory Pain: The Mediating Role of Solicitousness

Stories to Take the Edge Off Pain During Immunization for Preschoolers: A Randomized Controlled Trial

IMPORTANCE

Fear and distress during immunization may lead to long-term preprocedural anxiety and nonadherence to immunization schedules. Pictorial stories provide a way of educating the parent and child about the procedure.

OBJECTIVE

To determine the efficacy of pictorial stories in reducing pain perception among children and anxiety among mothers during immunization.

DESIGN

Three-arm randomized controlled trial Setting: Immunization clinic of a tertiary care hospital in South India.

PARTICIPANTS

Fifty children ages 5 to 6 yr, who reported to the hospital for measles, mumps, and rubella and typhoid conjugate virus vaccines. Inclusion criteria were that the child was accompanied by the mother and maternal knowledge of either Tamil or English. Exclusion criteria were child hospitalization in the past year or neonatal intensive care unit admission in the neonatal period.

INTERVENTION

Pictorial story regarding immunization before the procedure that contained information related to immunization, coping strategies, and distraction techniques.

OUTCOMES AND MEASURES

Pain perception was evaluated using the Sound, Eye, Motor Scale; the Observation Scale of Behavioral Distress; and the Wong-Baker FACES Pain Rating Scale (FACES). Maternal anxiety was measured using the General Anxiety-Visual Analog Scale.

RESULTS

Of 50 children recruited, 17 were in the control group, 15 were in the placebo group, and 18 were in the intervention group. Children in the intervention group reported lower pain scores on the FACES (p = .04) compared with the placebo and control groups.

CONCLUSIONS AND RELEVANCE

A pictorial story is a simple and cost-effective intervention to reduce pain perception among children. What This Article Adds: Pictorial stories may be a feasible, simple, and cost-effective intervention to reduce pain perception during immunization.

Clusters of facilitatory and inhibitory conditioned pain modulation responses in a large sample of children, adolescents, and young adults with chronic pain

Supplemental Digital Content is Available in the Text.

Findings from the current study add to the literature by describing different clinical phenotypes of central pain mechanisms of youth with chronic pain.

Introduction:

When investigating the role of facilitatory and inhibitory pain mechanisms such as conditioned pain modulation (CPM) and temporal summation of pain (TSP), it is important to take both into consideration in a single experimental model to provide the most information on subgroups of patients. Therefore, the objective of this study was to identify subgroups in a large population of pediatric patients with chronic pain based on their facilitatory and inhibitory pain mechanisms and compare them with control subjects.

Methods:

Five hundred twenty-one female subjects and 147 male subjects between 8 and 21 years old underwent a CPM assessment using a 2-minute tonic noxious heat stimulation as the test stimulus and a 2-minute cold-pressor task (CPT) (12°C) as the conditioning stimulus.

Results:

The best partition of clusters of patients was 3 clusters accounting for 27.15% of the total variation in the data. Cluster 1 (n = 271) was best characterized by high pain intensity during the CPT, lack of TSP during the test stimuli, and efficient inhibitory CPM. Cluster 2 (n = 186) was best characterized by low pain intensity during the CPT, lack of TSP during the test stimuli, and efficient inhibitory CPM. Cluster 3 (n = 151) was best characterized by high pain intensity during the CPT, presence of TSP during the test stimuli, and inefficient inhibitory CPM.

Discussion:

A single thermal CPM experimental design can identify combinations of facilitatory and inhibitory pain modulation responses. Findings from the current study add to the literature by describing different clinical phenotypes of central pain mechanisms of youth with chronic pain.

A Multi-Method Approach to Understand Parent Behaviors During Child Acute Pain

Abstract. Parent behaviors strongly predict child responses to acute pain; less studied are the factors shaping parent behaviors. Heart rate variability (HRV) is considered a physiological correlate of emotional responding. Resting or “trait” HRV is indicative of the capacity for emotion regulation, while momentary changes or “state” HRV is reflective of current emotion regulatory efforts. This study aimed to examine: (1) parent state HRV as a contributor to parent verbal behaviors before and during child pain and (2) parent trait HRV as a moderator between parent emotional states (anxiety, catastrophizing) and parent behaviors. Children 7–12 years of age completed the cold pressor task (CPT) in the presence of a primary caregiver. Parents rated their state anxiety and catastrophizing about child pain. Parent HRV was examined at 30-second epochs at rest (“trait HRV”), before (“state HRV-warm”), and during their child’s CPT (“state HRV-cold”). Parent behaviors were video recorded and coded as coping-promoting or distress-promoting. Thirty-one parents had complete cardiac, observational, and self-report data. A small to moderate negative correlation emerged between state HRV-cold and CP behaviors during CPT. Trait HRV moderated the association between parent state catastrophizing and distress-promoting behaviors. Parents experiencing state catastrophizing were more likely to engage in distress-promoting behavior if they had low trait HRV. This novel work suggests parents who generally have a low (vs. high) HRV, reflective of low capacity for emotion regulation, may be at risk of engaging in behaviors that increase child distress when catastrophizing about their child’s pain.

Testing the intergenerational model of transmission of risk for chronic pain from parents to their children: an empirical investigation of social transmission pathways

Children of parents with chronic pain have higher rates of pain and internalizing (eg, anxiety and depressive) symptoms than children of parents without chronic pain. Parental modeling of pain behaviour and reinforcement of child pain have been hypothesized to underlie these relationships. These mechanisms were tested in a sample of 72 parents with chronic pain and their children (aged 8-15 years). Standardized measures were completed by parents (pain characteristics, pain interference, and child internalizing) and children (pain catastrophizing, pain over previous 3 months, and internalizing). In a laboratory session, children completed the cold pressor task in the presence of their parent, and parent-child verbalizations were coded. Significant indirect effects of parental pain interference on child self-reported (B = 0.12, 95% confidence interval [CI]: 0.01-0.29) and parent-reported (B = 0.16, 95% CI: 0.03-0.40) internalizing symptoms through child pain catastrophizing were found (parental modeling mechanism), and were not moderated by child chronic pain status. Significant indirect effects were found between parent pain-attending verbalizations and child self-reported (B = 2.58, 95% CI: 1.03-5.31) and parent-reported (B = 2.18, 95% CI: 0.93-4.27) cold pressor task pain intensity and tolerance (B = -1.02, 95% CI: -1.92 to -0.42) through child pain-attending verbalizations (parental reinforcement mechanism). Although further understanding of the temporal relationships between these variables is needed, the current study identifies constructs (eg, parent pain interference, child pain catastrophizing, and parent reinforcement of child pain) that should be further examined as potential targets for prevention and intervention of pain and internalizing symptoms in children of parents with chronic pain.

"Tomorrow, I'll Be Fine": Impacts and coping mechanisms in adolescents and young adults with primary dysmenorrhoea

AIMS

To understand the experiences of adolescents and young adults with primary dysmenorrhoea through the lens of structured frameworks extant in contemporary pain literature.

DESIGN

Descriptive qualitative study.

METHODS

Thirty-nine adolescents and young adults (ages 16-24 years) with primary dysmenorrhoea participated in semi-structured in-person interviews. Transcripts of the interviews were analysed using deductive thematic analysis from November 2018 to April 2019.

RESULTS

Two overarching themes, each with subthemes, were identified. The first theme, primary dysmenorrhoea impacts the whole person, contained the following subthemes: biological, social, and psychological. The second theme, coping mechanisms of women with primary dysmenorrhoea, contained the following subthemes: primary, secondary, and passive coping.

CONCLUSION

Women experience several primary dysmenorrhoea-related impacts on their biological, social, and psychological functioning. Women employ a variety of coping mechanisms to manage their primary dysmenorrhoea pain.

IMPACT

This study emphasizes the significant effects of primary dysmenorrhoea on nearly every aspect of women's lives and contributes to an understanding of the ways women cope with this pain. The findings of this study underscore the need for continued consideration of primary dysmenorrhoea as a debilitating pain process as well as the need for additional interventions to help women manage this condition.

Parent Factors are Associated With Pain and Activity Limitations in Youth With Acute Musculoskeletal Pain: A Cohort Study

OBJECTIVES

Biopsychosocial models emphasize the influence of parent/family factors on pediatric chronic pain. Little is known about how parent factors differ across the acute to chronic pain continuum, or contribute to youths' pain experience in the acute pain period. The purpose of the study was to describe parent factors in youth with acute musculoskeletal pain (n=84) compared with youth with chronic pain (n=60) and youth without pain (n=61). Further, within the acute pain sample, we tested parent factors as predictors of child pain characteristics, as well as the moderating role of child sex on associations.

METHODS

Participants were 205 youth (age, 10 to 17) and one biological parent per child. Children reported on their own pain and activity limitations. Parents reported on their own chronic pain, somatization, and protective pain responses.

RESULTS

Parents of youth with acute pain had higher prevalence of chronic pain and greater somatization than parents of youth without pain. Parents of youth with acute and chronic pain did not differ. Linear regressions within the acute pain sample revealed presence of parent chronic pain and protective behavior were associated with child pain. Moreover, parent somatization was associated with child activity limitations. Within the acute pain sample, associations between parent protectiveness and child pain were moderated by child sex, with relationships stronger for female children.

DISCUSSION

Findings highlight the importance of parent factors on pain experiences of youth with acute musculoskeletal pain. Future longitudinal research can elucidate temporal associations that underlie how parent factors may impact transition from acute to chronic pain.

Parental Bonding in Adolescents With and Without Chronic Pain

Objective

Parental responses influence children's pain; however, the specific role of parental bonding in pediatric pain has not been examined. Depressive symptomology is frequently reported in children with chronic pain (CP) and may play a role in the relationship between parental bonding and pain. This study examined the connections between maternal/paternal bonding (perceived care and control) and symptoms of pain and depression in adolescents with CP and in healthy adolescents.

Method

Participants included 116 adolescents (aged 12-17) with CP (n = 55) and without (n = 61). Adolescents completed the Parental Bonding Instrument separately for their mother and father, as well as measures of depression and pain.

Results

Significant associations between parental bonding and adolescent pain and depression emerged in the pain group, but not in the healthy group. There were no differences in the impact of maternal versus paternal bonding on adolescent pain and depression. Mediation analyses revealed adolescent depression was a mediator of the relationship between maternal care and adolescent pain, and paternal control and adolescent pain in the group with CP.

Conclusions

This study highlights the importance of considering parental bonding and adolescent depression in pediatric CP, suggesting that high paternal control and low maternal care contribute to increased pain in adolescents through heightened adolescent depressive symptoms. The findings emphasize the need for family-based treatment for CP that addresses parent behaviors and adolescent mental health.

Current methodological approaches in conditioned pain modulation assessment in pediatrics

Conditioned pain modulation (CPM) paradigms have been used in various studies with healthy and non-healthy adult populations in an attempt to elucidate the mechanisms of pain processing. However, only a few studies so far have applied CPM in pediatric populations. Studies finding associations with chronic pain conditions suggest that deficiencies in underlying descending pain pathways may play an important role in the development and persistence of pain early in life. Twelve studies were identified using a PubMed search which examine solely pediatric populations, and these are reviewed with regard to demographics studied, methodological approaches, and conclusions reached. This review aimed to provide both clinicians and researchers with a brief overview of the current state of research regarding the use of CPM in children and adolescents, both healthy and clinical patients. The implications of CPM in experimental and clinical settings and its potential to aid in refining considerations to individualize treatment of pediatric pain syndromes will be discussed.

Psychological factors addressed in cognitive behaviour therapy for paediatric functional abdominal pain: Which are most important to target?

The effectiveness of cognitive behaviour therapy for paediatric functional abdominal pain leaves room for improvement. We studied which factors addressed in cognitive behaviour therapy relate most strongly to the physical and psychological functioning of children with functional abdominal pain and are thus most important to target. Questionnaires were filled out by 117 children with functional abdominal pain and their parents. Multiple regression analyses showed that children’s passive coping and parental and children’s positive cognitions relate to child functioning. Negative cognitions and parental solicitous behaviour were unrelated to child functioning. Cognitive behaviour therapy for functional abdominal pain may benefit most from changing children’s passive coping and promoting positive cognitions.
