Cultural differences between the American (dominant) and Hispanic (minority) cultures and inadequate mastery of the English language are the most salient problems in measuring psychological adjustment among Hispanics in the United States. Some dimensions of psychological adjustment (perception of reality, anxiety, self-esteem, depression, environmental mastery, anger) are relevant to both the dominant and the Hispanic cultures. There are some psychological instruments appropriate to measure these dimensions without cultural bias. Any psychological instrument should not be selected solely on the basis of validity and reliability. An additional consideration is the availability of the instrument in Spanish and the equivalence of that translated instrument in both languages. Failure to use equivalent versions may result in different means, variances, and norms. (Author/JAC)
