Psychometric evaluation of the Health Information Orientation Scale: a brief measure for assessing health information engagement and apprehension.

The Health Information Orientation Scale (HIOS) was developed from a need to briefly assess information orientation in a health context and underlying reasons for information seeking or avoidance. Using data from a larger longitudinal study of informal cancer caregivers, this study examines psychometric properties of the HIOS, including confirmatory factor analysis (CFA), reliability and construct validity through associations with information competence, coping and distress. CFA supported two conceptually unique factors: Information Engagement and Information Apprehension. Each factor demonstrated adequate reliability and construct validity, providing promising findings regarding Information Engagement and Information Apprehension, specific to a health context.
