Historically, the cornerstone of the psychologist’s identity rested on providing competent in-depth psychological assessment (Rapaport, Gill, & Schafer, 1946). The ability to utilize a battery of assessment methods to elucidate complex issues makes the psychologist unique among other mental health professionals. Recent trends, however, have tarnished that cornerstone. Not surprisingly, the movement away from proficiency in psychological assessment has led to a decline in the need for psychologists. In this chapter, we discuss these harmful trends, define psychological assessment, offer a model for assessing female offenders, and provide examples of how record review, clinical interview, the Hare Psychopathy Checklist-Revised (PCL-R), Personality Assessment Inventory (PAI), and Rorschach Inkblot test can be useful with female offenders. We discuss the interpersonal aspects of the assessment process, evaluate gender specific patterns for several PCL-R criteria (also see Appendices A & B), and provide caveats for assessing female offenders. We conclude with a case study.
