Ethical code of conduct in multicultural professional practice. Nondiscrimination Most ethical codes highlight the need for practitioners to be responsible in the course of delivering care to their clients. The high rate at which society has become culturally diverse has increased the significance of ethical codes in professional practice. Moreover, it is fundamental for practitioners in different professional fields to appreciate the importance of developing multicultural competence to be effective in executing their duties. Leung and Barnett (2007) define competence as “the ability and committed intention to consider cultural data in order to formulate accurate, comprehensive and impartial case conceptualizations” (p.2). Leung and Barnett (2007, p.3) further assert that most psychologists do not have the necessary multicultural competencies to enable them to undertake a broad cultural analysis of their clients to effectively engage in the acculturation process. Consequently, they are not able to resolve multicultural dilemmas adequately. Lack of such competence may result in unintended racism and the use of biased assessment instruments. Despite the incorporation of ethical codes by various practitioners, their dependence is not an assurance for multicultural competence. Corey, Corey, and Callanan (2011) assert that this limitation emanates from the failure of ethical codes to take into account various multicultural dimensions. One of the areas of multicultural professional practice relates to mental health. Corey, Corey, and Callanan (2011) assert that there are standards/codes of conduct established by practitioners in mental health such as the Council for Accreditation of Counseling and Related Educational Programs (CACREP). Practitioners in this field are required to refrain from discriminating their clients based on variables such as age, race, sexual orientation, or social class (Corey, Corey & Callanan, 2011). However, this code is limited concerning multicultural professional practices. One source of limitation to this code of ethics arises from the use of assessment instruments that do not take into account the multicultural population. For example, using pseudo-etic instruments in the process of undertaking a cultural assessment for multicultural populations may lead to inaccurate evaluation and treatment. Additionally, practitioners may misunderstand clients from a culturally diverse population. The occurrence of such incidences may result in discrimination. Corey, Corey, and Callanan (2011) further contend that some practitioners exercise discrimination based on race, age, and sexual orientation. Corey, Corey, and Callanan (2011) assert that the failure of practitioners to incorporate cultural diversity in their practice is an infringement of clients’ basic human rights and cultural autonomy. Such discriminative actions adversely affect the effectiveness of such professional practices in helping multicultural populations. To eliminate such discrimination, practitioners dealing with multicultural populations should be adequately trained to deal with diversity issues.
