The role of pain-related anxiety in adolescents' disability and social impairment: ALSPAC data.

BACKGROUND: Anxiety, in particular pain-related anxiety, plays an important role in explaining the severity of pain complaints and pain-related disability in both adults and children with chronic pain. The fear-avoidance model (FAM) describes how pain-related anxiety plays a critical role in the maintenance of pain-avoidance behaviour, which in turn influences pain-related disability. However, the FAM does not take into account broader aspects of adolescence, such as social functioning, which could be negatively impacted by anxiety. In addition, most studies examining the role of anxiety in pain have used small convenience or clinical samples. By using a large UK epidemiological database, this study investigated the associations between pain-related anxiety, disability and judgements of social impairment. METHODS: Participants (n = 856) with recurrent pain were selected from a larger epidemiological study (Avon Longitudinal Study of Parents and Children) of adolescents attending a research clinic at the age of 17 (n = 5170). Adolescents completed a self-report questionnaire on pain-related anxiety, disability and perceived social impairment. RESULTS: High levels of pain-related anxiety were associated with more disability. In girls, higher levels of pain-related anxiety were also related to the self-perception of greater impairment in social functioning compared with their peers. CONCLUSIONS: Pain-related anxiety was associated with greater pain-related disability and impaired social functioning. Social functioning should be explored as an integral part of fear-avoidance models of adolescent chronic pain.

Parental catastrophizing about child's pain and its relationship with activity restriction: the mediating role of parental distress.

Recent research has demonstrated that parental behaviors have an important impact upon child and adolescent pain outcomes. At present, however, we do not know which parents engage in particular behaviors and why. In 2 studies, the impact of parental catastrophizing about their child's pain upon parental tendency to stop their child's pain-inducing activity was investigated. Further, the mediating role of parental distress was explored. In study 1, a sample of schoolchildren (n=62; M=12.48 years; SD=1.72) took part in a cold-pressor task. In study 2, a clinical sample of adolescents with chronic pain (n=36; M=15.68 years; SD=1.85) performed a 2-min walking task designed as a pain-inducing activity. In both studies, the accompanying parent was asked to watch their child performing the pain task. Findings revealed, for both studies, that parents with a high level of catastrophic thinking about their child's pain experienced more distress and a greater behavioral tendency of wanting to stop their child's pain-inducing activity. Further, parental feelings of distress mediated the relationship between parental catastrophic thinking and parents' tendency to restrict their child's activity. The findings are discussed in light of an affective-motivational conceptualization of pain and pain behavior. Parental catastrophizing was associated with parental tendency to restrict their child's engagement in a painful test, and this relationship was mediated by parental distress.
