Resilience Factors and Physical Activity Engagement in Adolescents with Chronic Musculoskeletal Pain: A Cross-Sectional Study

This is the authors' abstract. We don't add key points for this paper.

Background/Objectives: Chronic musculoskeletal pain (CMSKP) affects up to 40% of adolescents and leads to substantial disability, reduced quality of life, and long-term health risks. Physical activity is central to treatment, but adherence to moderate-to-vigorous physical activity (MVPA) is inconsistent. We evaluated higher-resilience constructs—self-efficacy, pain acceptance, motivational stage, and affect—and hypothesized that higher resilience would be associated with greater objectively measured physical activity, better daily functioning, and higher quality of life in adolescents with CMSKP. Methods: Forty-three adolescents (13–18 years) with CMSKP completed measures of physical activity-specific self-efficacy, acceptance (AFQ-Y), motivational stage (PSOCQ-A), and affect (PANAS-C). Participants wore activPAL monitors to assess MVPA, light activity, and sedentary time. Physical function endurance was measured by the six-minute walk test (6MWT) and the Functional Disability Inventory (FDI); quality of life by the Pediatric Quality of Life Inventory (PedsQL). Spearman’s correlations assessed associations among resilience variables, physical activity metrics, 6MWT distance, FDI, and PedsQL. Results: MVPA was correlated positively with 6MWT distance (ρ = 0.48, p = 0.002) and negatively with FDI scores (ρ = −0.56, p < 0.001). Self-efficacy related to higher MVPA (ρ = 0.41, p = 0.009), better endurance (ρ = 0.36, p = 0.017), and lower disability (ρ = −0.38, p = 0.013). Acceptance was correlated with PedsQL total (ρ = 0.45, p = 0.004); motivation (specifically maintenance) scores were correlated with higher quality of life (ρ = 0.33, p = 0.027). Light activity and sedentary time were not significantly linked to functional or psychosocial outcomes. In a step-wise regression, only physical activity self-efficacy for ambulation at school predicted MVPA, B = 1.56, p = 0.008. Conclusions: Resilience constructs—including self-efficacy, acceptance, and readiness to change—were meaningfully associated with MVPA, daily functioning, and quality of life, and may have implications for treatment development.
