Persons of Hispanic origin are the largest ethnic minority group in the United States. Practitioners involved in personality assessment will undoubtedly work with Hispanic clients who may be grappling with low English proficiency and other challenges of acculturation to U.S. society. Written by front-line experts in the use of the Minnesota Multiphasic Personality Inventory (MMPI), Assessing Hispanic Clients Using the MMPI-2 and MMPI-A discusses the utility of psychological tests based on U.S. norms in making clinical decisions for clients from different cultural backgrounds. The MMPI instruments are the most extensively researched and widely used personality instruments with Spanish-speaking clients. The authors provide readers a critical sociocultural context in the use of the MMPI-2 and MMPI-A in the clinical assessment of Hispanic clients in the U.S. and abroad. Psychologists and other practitioners are offered a practical guide for clinical interpretation of test results, with advice on addressing biases, challenges to protocol validity, and other potential barriers to the culturally appropriate and ethical use and interpretation of the tests. Butcher, Cabiya, Lucio, and Garrido provide a comprehensive review of the research literature, past and contemporary, on the use of the MMPIs with Spanish-speaking populations in the U.S. and internationally. The authors describe the development and validation of Spanish-language versions of the MMPI-2 and MMPI-A, offering scenarios from Mexico, Cuba, and other Spanish-speaking countries. A set of appendices include T score conversion tables for the Mexican MMPI versions and a listing of Spanish language translations.
