The Readiness to Return to Duty Questionnaire (RDRQ) is a recently developed screening instrument for detecting fear-avoidance behavior in a military musculoskeletal pain population. The RDRQ was developed based on the Fear-Avoidance Model which postulates four factors resulting in overall fear-avoidance behavior. While research investigating the factor structure of the RDRQ does not exist, research investigating the factor structure of other measures of fear avoidance have found evidence of one and two factor solutions. In the present paper we assess the adequacy of the proposed factor structure of the RDRQ using confirmatory factor analysis. The results favor a three-factor model. Theoretical implications for research using the RDRQ are discussed.

Chronic pain due to musculoskeletal injury is one of the leading causes of disability and reduced combat readiness in the U.S. Army. Unidimensional pain management systems are not effective in addressing the complex phenomenon of pain-related disability. Growing evidence has supported use of the Fear Avoidance Model (FAM) as a suitable model to address pain-related disability and chronicity from a multidimensional pain neuroscience approach. While several fear avoidance measurement tools exist, one that addresses the complexity of the Army environment encouraged the authors to develop and test the reliability and validity of a military specific questionnaire. This study developed and validated an Army specific fear avoidance screening, the Return to Duty Readiness Questionnaire (RDRQ), which subsequently demonstrated good psychometric properties. Reliability coefficients demonstrate high internal consistency values both during pilot study (α = 0.96) and validation study (α = 0.94, ωt = 0.94). A Correlation Coefficient of 0.74 when compared with the Fear Avoidance Components Scale (FACS) suggests good concurrent validity. Future study should include replication in a new army population, investigation of responsiveness, test-retest reliability, structural validity and establishing severity scores with minimal clinically important differences to enhance utility.
