Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

* There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).

Equipment Needs

While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges that these questions can be administered in a noncomputerized format (i.e. paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer or handheld computer to administer a computer-assisted questionnaire.

Requirements

Definition

Questions about renovations to the home in the last year with optional questions about personal activities in the last 48 hours.

Purpose

Paints, adhesives, and other chemicals used to renovate homes may affect a person’s health for a time after the renovation occurred. In addition, normal daily activities may include exposure to paints, solvents, gasoline, wood dust, combustion emissions, and other substances.

Selection Rationale

The protocol includes questions to assess exposure to air contaminants in the last year and last 48 hours, focusing on a common indoor air pollution source-home renovations. In addition, a series of questions about daily activities identifies other potential sources of air pollutants.
