Background and Aims Clinicians treating paediatric chronic pain conditions understand that persistent pain, functional ability, and symptoms of depression often co-exist, yet these relationships have only been described to a limited extent by research. This paper more closely examines the relationship between symptoms of depression and subtypes of functional disability. Methods Participants included a clinical sample of children and adolescents ( N = 239) referred to a paediatric multidisciplinary pain clinic for treatment of persistent or recurrent (chronic) pain in Australia. The majority of participants were female, (76.6%), and were aged 7–17 years (mean age at the time of presentation was 13.8 years). Data from standardized instruments and interview data were collected from a clinical file audit. The Pediatric Outcomes Data Collection Instrument (PODCI) was used as a measure of functional difficulties performing activities of daily living, and the Children's Depression Inventory (CDI) was used to measure depressive symptoms. Results High rates of depression and functional disability were observed, but were not associated with one another beyond relatively weak associations. Contrary to prior studies using different measures of physical functioning, depression symptoms were not associated with PODCI functional disability beyond a minor association with anhedonia symptoms (primarily driven by the pain/comfort subscale of the PODCI). Conclusions and Implications We argue that prior research has measured physical functional limitations in paediatric pain sufferers in a way that is heavily influenced by psychosocial factors, in particular by the symptoms of clinical depression. In contrast, using a measure of physical functioning (PODCI) less influenced by psychosocial factors suggests that the relationship between physical functioning during activities of daily living (e.g., use of upper limbs, basic gross and fine motor skills, basic mobility) and depression is weaker, despite both being heightened in this sample. Unlike other functional disability measures, the Pediatric Outcomes Data Collection Instrument (PODCI) may allow researchers to assess functional limitations somewhat independently of depression symptoms. This conclusion requires replication in further studies, but if confirmed, then the PODCI could be advocated as a useful measure to obtain a more ‘pure’ measure of functional difficulties due to pain, relatively independent of depression.

Pediatric persistent pain is associated with poorer physical and psychosocial functioning in children, as well as immediate and long-term societal costs. Onset typically occurs in early adolescence, suggesting that late childhood is a key window for identifying potential intervention targets before pain symptoms become entrenched. This study used population-based data from the Longitudinal Study of Australian Children (n = 3,812) and adopted a biopsychosocial and ecological systems approach to investigate child, family, and sociodemographic factors associated with pain problems in children transitioning to adolescence. The prevalence of at least weekly parent-reported pain in the study sample was approximately 5% at 10 to 11 years of age, and pain continued at 12 to 13 years of age for 40% of these children. Key factors at 10 to 11 years that uniquely predicted parent-reported pain problems at 12 to 13 years were frequency of previous pain (1-3 times weekly: odds ratio [OR] = 7.49; 95% confidence interval [CI], 4.3-13.0; 4-7 times weekly: OR = 17.8; 95% CI, 8.7-36.5) and sleep difficulties (OR = 1.86; 95% CI, 1.16-2.97). This study highlights the importance of early intervention for persistent pain in childhood, because pain complaints in late childhood tend to persist into early adolescence.Perspective: This article used a biopsychosocial and ecological systems approach to understanding predictors of pain problems during the transition to adolescence within a nationally representative community-based cohort. Sleep difficulties at 10 to 11 years uniquely predicted pain at ages 12 to 13 years, suggesting that early intervention using sleep interventions may be a promising direction for future research.

Abstract: Although sex differences have been investigated in chronic pain populations, little is known about sex differences in the pain experience of paediatric oncology patients and also whether their parents rate the pain experience differently for boys and girls. The aim of the present study was to determine if (1) boys and girls with cancer differ in current perception and past recollection of cancer-related pain and (2) if adolescents'' and parents'' pain ratings differ in relation to the sex of the adolescent. One hundred twelve adolescents with malignant diagnoses (12 to 18 years) and their parents participated in the study. Girls reported higher pain intensity within the last 7 days and 4 weeks despite similar diagnosis, physical status, duration of diagnoses, and main pain causes. When asked for pain intensity that dated back in time, parent and adolescent ratings diverged, with a trend for parents to reporting higher pain intensity in boys and lower pain intensity in girls, particularly for pain in the preceding 7 days. The present study provides preliminary evidence for sex differences in the recalled pain experience of adolescents with malignant diagnoses. Although boys and girls experience present pain similarly and hence should be treated similarly, girls recall higher pain intensity than boys. Future studies should address whether negative memories in girls play a significant role and may have an impact on girls'' well-being and pain-related distress. Additionally, psychosocial factors such as gender role expectations may need to be investigated. Parental variables and their impact on parents'' pain ratings, especially for ratings of precedent pain, warrants further investigation. Perspective: Girls with malignant diagnoses differ from boys in their recalled pain intensity ratings, with girls reporting higher pain intensity. Additional pain management strategies referring to the memory of pain may need to be implemented. [Copyright &y& Elsevier]
