Building informed consent for cholinesterase monitoring among pesticide handlers in Washington State.
BACKGROUND: Pesticide handlers in Washington State are predominantly Mexican and, therefore, require a culturally appropriate process of informed consent. In addition, members of this occupational group are vulnerable to coercion because of poverty, lack of insurance, inability to read, and employment status METHODS: To create a process of culturally competent informed consent for Washington State's cholinesterase monitoring program, we used focus groups to collect data about cultural beliefs, attitudes, knowledge, language, and traditions of Mexican-American pesticide handlers. With this information, we developed a final consent form and evaluated it using a 10-item test-retest questionnaire in a sample of 103 handlers. RESULTS: Using qualitative methods, we created English and Spanish consent forms that incorporated culturally defined risk information. Both the written and audiotape formats significantly improved comprehension; but, for subjects with less than 7 years of schooling, audiotapes in Spanish yielded significantly higher scores (mean comprehension score 7.0 vs. 6.1, t = - 2.2, P = 0.03). CONCLUSIONS: Culturally competent informed consent for particularly vulnerable populations of non-native speakers of English is possible. It requires both knowledge of specific cultural elements and the application of appropriate technology.
