The effects of autistic traits in adolescents on the efficacy of paediatric Intensive Interdisciplinary Pain Treatment (IIPT).

Autistic adolescents are at greater risk of chronic pain, but it is unclear how autistic features may relate to individual aspects of chronic pain. As autism traits exist in the general population as well, it is important to know if autistic traits could impact how effective chronic pain management is for adolescents. Here we examined autistic traits in 112 patients (12–18yrs) recruited from a UK national specialist adolescent pain rehabilitation programme. Participants completed screening questionnaires for autistic traits upon entry to the programme, as well as clinically recognised pain measures before and after the 3-week treatment program. Autistic traits predicted greater psychological challenges at treatment onset. Critically, autistic traits were not related to the magnitude of improvement in pain measures during the pain management program. Our study suggests that adolescents with greater autistic traits may benefit from existing pain rehabilitation programs at similar rates to their peers. Additionally, these data suggest no reason for therapeutic pessimism for autistic pain patients. We do however acknowledge that these data may differ in populations with an autistic diagnosis, and that barriers may still exist for autistic people in treatment for pain. Perspective: Autistic traits were explored in patients undergoing an Intensive Interdisciplinary Pain Treatment (IIPT). Higher autistic traits correlated with more pain related psychological difficulties at intake. Autistic traits were not related to the magnitude of improvement following IIPT. Our data therefore suggests that autism should not be a barrier to IIPT. Data availability: Data is held in the PAIRED Pain Rehabilitation Database: Bath and Bristol, individual data used in the current analyses are therefore not available.
