This study sought to better understand the associations between perfectionistic self-presentation and measures of pain intensity, pain catastrophizing, pain interference, and fatigue in children and adolescents with pain. In the study, 218 adolescents responded to measures of perfectionistic self-presentation (i.e., perfectionistic self-promotion, nondisplay of imperfection and nondisclosure of imperfection), pain intensity, pain catastrophizing, pain interference, and fatigue. Four hierarchical regression analyses and three mediation analyses were conducted. Our results showed that perfectionistic self-promotion was significantly and independently associated with pain intensity and that nondisplay of imperfection was significantly and independently associated with pain catastrophizing, pain interference, and fatigue. Nondisclosure of imperfection was not significantly associated with any criterion variable. Pain catastrophizing mediated the association between both perfectionistic self-presentation and nondisplay imperfection and pain interference but not between nondisclosure of imperfection and pain interference. The findings provide new information about the role of perfectionistic self-presentation in children and adolescents' experience of pain. These findings, if replicated, support perfectionism as a potential target of pain treatment in young people.

Chronic pain is a significant health problem which interferes with patients daily functioning and quality of life. Valid and reliable measures of pain-related interference are needed to provide adequate care to patients and monitor changes in pain and functioning over time. This study sought to evaluate the reliability and validity of a Portuguese version of the Brief Pain Inventory (P-BPI) interference scale. Two hundred and fourteen patients with chronic musculoskeletal pain completed the P-BPI, 0-10 NRS of pain intensity, Short Form-12 Health Status Questionnaire (SF-12), Hospital Anxiety and Depression Scale (HADS). The P-BPI demonstrated excellent internal consistency (Cronbach’s alpha = .91) and showed moderate associations with the criterion measures (all rs .30 or larger), supporting its construct validity. Confirmatory factor analysis of the P-BPI items yielded a single factor, further supporting its construct validity. The results provide strong support for the reliability and validity of the P-BPI interference scale.
