BackgroundFear of pain is important in the development and maintenance of chronic pain. The Fear of Pain Questionnaire-Child version has been developed to assess pain related fear in children and adolescents.ObjectiveTranslating the original questionnaire into Dutch, and investigating internal consistency and construct validity to enable use in the Dutch pain rehabilitation setting for treatment and research.MethodsCross-sectional validation study: After forward and back translation of the FOPQ-C, adolescents (11-22 years old) with chronic musculoskeletal pain completed an assessment containing the Dutch Fear of Pain Questionnaire, and questionnaires about demographics, pain catastrophizing, functional disability, and pain intensity. Internal consistency and construct validity were evaluated through exploratory factor analysis (principal axis factoring with oblique rotation) and hypotheses testing using pain catastrophizing, functional disability, and pain intensity as comparative constructs.ResultsEighty-six adolescents completed the assessment. Exploratory factor analysis resulted in a two-factor structure, explaining 43% of the variance. Internal consistency was strong (Cronbach's α = 0.92 total scale, α = 0.88 factor 1, and α = .86 factor 2). Five out of 6 hypotheses were confirmed.ConclusionsThe Dutch version demonstrated good internal consistency and good construct validity in a population of adolescents with chronic musculoskeletal pain. Implications for rehabilitation The Fear of Pain Questionnaire-Child version was developed to measure fear of pain and avoidance in children and adolescents with chronic pain. Identification of fear of pain and activities that are being avoided are important during screening and assessment of the adolescent for chronic pain rehabilitation treatment. The presence of fear of pain and/or avoidance behavior is important information to shape and target multidisciplinary rehabilitation treatment.
