Abstract
Introduction: The etiology and consequences of chronic vulvar pain are multidimensional, resulting in highly variable clinical presentations and no established treatment algorithm. Inconsistent use of measurement tools across studies is a significant barrier to drawing conclusions regarding etiology and treatment. In a companion paper, we review additional methodological challenges to the study of chronic vulvar pain and potential solutions.Aim: To review and recommend assessment and measurement tools for vulvar pain and associated key outcomes.Methods: The authors reviewed the scientific evidence related to measurement of vulvar pain and made decisions regarding recommendations via discussion and consensus.Main Outcome Measure: We assessed measurement tools for vulvar pain and related outcomes and considered advantages and disadvantages of their use.Results: Empirically validated measurement tools are available and should be used uniformly across studies to support comparisons and pooling of results. There is, at times, a trade-off between advantages and disadvantages when selecting a particular tool, and researchers should be guided by their specific research aims, feasibility, and potential to gain further knowledge in the field. Researchers should incorporate a biopsychosocial assessment of vulvar pain and its consequences.Clinical Implications: This review provides a comprehensive list of measurement tool recommendations for use in clinical research, and in some cases, clinical practice.Strengths & Limitations: This expert review can guide study design and decision-making for those researching vulvar pain and its consequences. The review content and recommendations are based on expert knowledge of the literature rather than a formal systematic review.Conclusion: A thorough consideration of vulvar pain assessment tools is essential for continued progress toward identifying factors involved in the development and maintenance of vulvar pain and developing empirically supported treatments.
