Specialized methods are necessary when collecting data from illiterate and low literate populations. They are sometimes ashamed of their reading deficiencies and would prefer not to disclose them.
We will be approaching migrant pesticide handlers in the Yakima Valley who are participating in a larger study Identifying Risk Factors for Cholinesterase Depression among Pesticide Handlers in Washington State (Hofmann, J., 2006).
In this population of illiterate and low literate workers, we propose that even if they are not computer literate they will rate the computer at the same level as the face to face.
If we can show that the Audio Computer Assisted Self Interview (ACASI) can replace the face to face interview, it could add information to the electronic medical record when addressing this special population.
Computer based assessments are highly acceptable to individuals in low income populations. This study will find out if this is also the case among illiterate and low literate migrant workers. It will also find out the motivation for their participation.
Veracity of participant responses to ACASI system will be tested by confirming question comprehension during the face to face interview.
The subjects will be interviewed to determine the extent of their understanding of the research process. Their perception about University's involvement in the research and their beliefs about the potential benefit of the research to them.
For the index Kappa our aim is in the range of 0.80 or above.
