Stuck on pain? Assessing children's vigilance and awareness of pain sensations.

Abstract

Attending towards pain is proposed as a key mechanism influencing the experience and chronification of pain. Persistent attention towards pain is proposed to drive poor outcomes in both adults and children with chronic pain. However, there are no validated self-report measures of pain-related attention for children. The goals of this study were to adapt the Pain Vigilance and Awareness Questionnaire (PVAQ) for use in a child sample, to preliminary examine its psychometric properties, and to assess its utility over and above a measure of general attentional capacities. We adapted the language of the PVAQ to be more easily understood by children as young as 8years. In a sample of 160 children (8-18years) with chronic pain, we examined the factor structure, internal consistency and criterion validity of the PVAQ-C. The PVAQ-C demonstrated excellent internal consistency (α=0.92) and moderate-to-strong criterion validity. A one-factor structure best fit the data. Children who reported greater attention to pain also reported greater pain catastrophizing, fear of pain, avoidance of activities and poorer physical functioning. Pain-related attention remained a significant predictor of functioning while controlling for demographics, catastrophizing and fear-avoidance. Pain-related attention also significantly predicted child outcomes independent of the child's general attention control capacities, indicating added value of a pain-specific measure of attention. The PVAQ-C shows strong indices of internal reliability and criterion validity, and indicates unique predictive utility. It will be important to study the role of pain-related attention in youth within developmental and functional-motivational frameworks. Pain-related attention is proposed as a key factor influencing fear-avoidance outcomes in both adults and youth with chronic pain, yet no self-report measures of pain-related attention have been validated for children. This paper presents a child version of the Pain Vigilance and Awareness Questionnaire (PVAQ-C), which indicates strong internal consistency, criterion validity and unique predictive validity, and provides evidence to support the Fear-Avoidance Model in youth with chronic pain.
