In addition to standard medical care, children and parents in the online behavioral intervention will receive access to the full web-based program including education about chronic pain, training in behavioral and cognitive coping skills, instruction in increasing activity participation, and education about pain behaviors and parental operant strategies using an engaging, interactive format on the Internet.

The Online Patient Education group will serve as an attention control condition. In addition to standard medical care, children and parents will be provided with access to a modified version of the study website that will provide information from publicly available educational websites about pediatric chronic pain management.

The online behavioral intervention is travel-themed and participants visit 8 destinations (1 per week) designed to take 30 min each to complete. The destinations serve as an online analog for the weekly sessions used when delivering behavioral interventions face-to-face. The 8 child destinations include: 1) education about chronic pain, 2) recognizing stress and negative emotions, 3) relaxation and distraction skills, 4) school, 5) cognitive skills, 6) sleep hygiene and lifestyle, 7) staying active, and 8) relapse prevention. The eight parent destinations include: 1) education about chronic pain, 2) recognizing stress and negative emotions, 3) operant strategies I, 4) operant strategies II, 5) modeling, 6) sleep hygiene and lifestyle, 7) communication, and 8) relapse prevention.

Child report of activity limitations will be assessed using the prospective version of the Child Activity Limitations Interview (Palermo, Witherspoon, Valenzuela, & Drotar, 2004), which includes 8 activities that children identify as important in their day-to-day lives that are impacted by pain. Responses are rated on a 5-point scale (0-4) with higher scores indicating greater perceived difficulty with activities. Children will provide ratings daily for 7 days on their online diaries at each assessment period. Mean activity limitations across the reporting period is used in analyses.

Children will report on presence and intensity of pain daily for 7 days at each assessment period. Pain intensity will be assessed using an 11-point numerical rating scale (NRS) with anchors of 0= no pain to 10= worst pain (McGrath et al., 2008). Mean average intensity of the pain reported will serve as primary pain measure.

Children will complete the Bath Adolescent Pain Questionnaire (BAPQ), a 61-item scale that will be used to measure pain-specific emotional functioning (Eccleston et al., 2005). The BAPQ was developed specifically for children with chronic pain and has demonstrated adequate reliability and validity (Eccleston et al., 2008). For the purpose of this study, the subscales of depression and pain-specific anxiety will be used in analyses.
