The injury illness sensitivity index – Revised: Further validation in a Dutch community sample

Confirmatory factor analysis confirmed two correlated factors in the ISI-R: Fear of Injury and Fear of Illness. The measure’s validity was supported by strong correlations between the ISI-R and wellestablished pain and physical health-related anxiety measures, moderate correlations with measures that reflect general negative emotionality (e.g. anxiety, depression), and weak correlations with fear constructs that do not entail a direct link to a health threat.

These results indicate the appropriateness of working with the Dutch ISI-R and its two subscales as a reliable and valid measure of fear of physical harm, Fear of Illness and Fear of Injury.
