This content analysis examined assessments available for the screening of sex trafficking to provide professional counselors further insight into the features of sex trafficking and how to best identify and measure this phenomenon. The authors reviewed 12 articles that included a complete or partial use of 13 instruments and completed a content analysis using Krippendorff’s procedures. The final analysis resulted in five overarching categories: (a) commercial sexual exploitation, (b) risk factors, (c) forms of abuse, (d) mental and physical health assessment, and (e) unstable living conditions and caregiving. The authors also provide psychometric information for each available sex trafficking instrument. Discussion, implications for clinical practice, and recommendations for future research are provided.
