Assessment Mode and Validity of Self-Reports in Adults
This study will examine how the assessment mode influences the validity of self-reported
adherence to asthma therapy. Self-reported adherence to asthma therapy data will be collected
using one of three randomized assessment modes (interview, computer, or telephone).
adherence to asthma therapy. Self-reported adherence to asthma therapy data will be collected
using one of three randomized assessment modes (interview, computer, or telephone).
BACKGROUND:
Self-reports are a primary source of behavioral data. Studies have highlighted the variable
validity and reliability of self-report measures of health behaviors such as adherence to
therapy. Research on self-reports of sensitive information, such as sexual behavior and drug
use, suggests that the mode of data collection may enhance validity of self-reports. However,
no studies have determined how the mode of data collection influences self-reports when an
objective measure of the behavior is available.
DESIGN NARRATIVE:
The primary aim of this study is to examine the influence of the mode of data collection on
the validity of self-reports of inhaled anti-inflammatory medication adherence.
The key secondary outcomes of the study will attempt to answer the following questions: 1)
does the assessment mode influence self-reports of commonly used asthma outcome measures of
disease-related symptoms, self-management behaviors, and quality of life?; 2) does the
relationship between the assessment mode, the validity of self-reports of adherence, and
other measures (i.e., asthma symptoms, self-management behaviors, and quality of life) change
over time?; and 3) does the assessment mode interact with baseline personality
characteristics and mood to influence the validity of self-reports of adherence and other
outcome measures (i.e., asthma symptoms, self-management behaviors, and quality of life)?
