Extracting Response Style Bias From Measures of Positive and Negative Affect in Aging Research

摘要

ObjectivesThis study investigated the role of response style biases in the assessment of positive and negative affect in aging research; it addressed whether response styles (a) are associated with age-related changes in cognitive abilities, (b) lead to distorted conclusions about age differences in affect, and (c) reduce the convergent and predictive validity of affect measures in relation to health outcomes.
