Abstract
Three fundamental fears—anxiety sensitivity, fear of negative evaluation, and injury/illness sensitivity—are believed integral components of anxiety-related psychopathologies. S. Taylor (1993) performed a cumulative factor analysis on measures of these and found them factorially distinct. Subsequently, separate factor analyses have been performed on measures of anxiety sensitivity and fear of negative evaluation. No such analysis exists for the Injury/Illness Sensitivity Index (ISI; S. Taylor, 1993). The ISI, an 11-item self-report questionnaire intended to measure fear of illness and injury, has the potential to inform the understanding of mechanisms underlying anxiety-associated chronic health conditions. The primary purpose of this study was to assess the factor structure and psychometric properties of the ISI. A principal components analysis with oblique rotation, conducted on data from 122 participants, suggests the ISI comprises two distinct lower order factors—Fear of Illness and Fear of Injury—that load onto a higher order factor of Fear of Physical Harm.
