The purpose of this study was to examine the associations between anxiety, depressive symptoms, and pain catastrophizing with pain medication use in adolescents with chronic pain, and to explore if these associations differed by sex. The results showed that pain catastrophizing was a unique predictor of pain medication use. There was no moderating effect of sex on the associations between psychological factors and pain medication use.
Objective The purpose of this study was to examine (1) the associations of anxiety, depressive symptoms, and pain catastrophizing with pain medication use in adolescents with chronic pain and (2) the extent to which these associations differed as a function of adolescents' sex. Methods Cross-sectional data from 320 adolescents 12-18 years of age with chronic pain were drawn from an epidemiological study on pediatric chronic pain conducted in Reus (Catalonia, Spain). Participants were asked to provide sociodemographic information and respond to measures assessing pain (location, frequency, intensity, and interference), pain medication use, anxiety, depressive symptoms, and pain catastrophizing. Point biserial correlations were conducted to examine univariate associations between the psychological variables and pain medication use. Hierarchical logistic regression analysis was used to examine these associations while controlling for demographic characteristics, pain intensity, and pain interference. Results Anxiety, depressive symptoms, and pain catastrophizing were significantly associated with pain medication use in univariate analyses. Regression analysis identified pain catastrophizing as a unique independent predictor of pain medication use after controlling for the effect of demographic variables (sex and age), pain intensity, and pain interference (odds ratio = 1.1, P < .05). No moderating effect of adolescents' sex on the associations between psychological factors and pain medication use was found. Conclusions Adolescents with chronic pain with higher levels of pain catastrophizing use pain medications more often. Research to examine the impact of interventions targeting pain catastrophizing on pain medication use among adolescents with chronic pain would be an important next step.
