ABSTRACT Background and Objective Despite growing interest in mindfulness‐based interventions for adolescents with chronic pain, the data have not been systematically summarized. We conducted a systematic review and meta‐analyses to estimate the effect of mindfulness‐based interventions on pain intensity, catastrophizing, acceptance and interference; functioning, quality of life, and anxiety and depression in youth with chronic pain. Databases and Data Treatment Electronic databases CINAHL, CCTR, Embase, Medline, PsycINFO, Scopus and Web of Science were systematically searched to January 2, 2025. Studies were included if they were in English, included > 5 patients, were not part of intensive interdisciplinary pain treatment and included pre‐post outcomes from mindfulness‐based interventions delivered to adolescents with chronic pain. Risk of bias was assessed with the Newcastle–Ottawa Scale. Results Fourteen studies including a total of 323 adolescents were identified. There were significant within group improvements in pain intensity, pain catastrophizing, pain acceptance, pain interference, functioning, depression, anxiety, and quality of life, with results maintained or increased at follow‐up effect sizes at follow‐up were moderate to large (e.g., quality of life SMD = 0.33; pain intensity SMD = −0.73; pain interference SMD = −1.44). Heterogeneity of results was generally moderate to high. Compared to standardized long interventions, variable length interventions showed greater pre‐post changes in functioning, pain intensity, and pain catastrophizing. The certainty in the estimates was generally low, due to risk of bias and pre‐post designs. Conclusions Although adolescents with chronic pain report improvements after participating in mindfulness‐based interventions, rigorous RCTs are needed to substantiate these results. Significance Statement Chronic pain in youth is common and difficult to treat. Previous interventions have largely been based on cognitive‐behavioural therapy and not successful for all. This is the first systematic review and meta‐analysis in paediatric chronic pain to focus on mindfulness‐based interventions, highlighting an alternative and potentially effective intervention approach. This study informs clinicians about an effective intervention approach and assists researchers in identifying gaps for further research.

Background/Objective: The COVID-19 pandemic led to a widespread transition to online learning. Yet, it is unclear how this shift in learning format impacted school attendance in adolescents with chronic pain, a group that struggles with school absenteeism. This study compared school attendance and format (e.g., in-person, online) in patients with chronic pain attending an Intensive Interdisciplinary Pain Treatment Program (IIPT) before the pandemic to an age- and gender-matched sample of youth attending the program after the pandemic. Methods: Participants were 226 school aged adolescents (13–18 years; M age = 15.89, SD = 1.46) enrolled in an IIPT before and after the COVID-19 pandemic. Patients admitted before March 2020 (pre-pandemic group; n = 113) were compared to an age- and gender-matched group of patients who were admitted to the IIPT from November 2021 to November 2023 (post-pandemic group = 113). Upon admission to the program, participants completed validated measures of internalizing symptoms and functional disability. They also completed structured questions related to pain and school history. Results: Significantly more patients in the post-pandemic group were attending school through online and home-schooling options (p < 0.01). Youth who attended the IIPT after the pandemic missed fewer school days (p < 0.05) than those who attended before the pandemic. The groups did not differ in functional disability or internalizing symptoms. However, participants in the post-pandemic group who attended online school missed more school days (p < 0.01) and experienced greater functional disability (p < 0.05) than those who attended in person. Conclusions: The findings highlight how the COVID-19 pandemic may lead to sustained changes in the way adolescents with chronic pain attend school, with implications for increased functional disability and school dropout among this vulnerable population.
