Psychometric properties of the Iranian version of the Facts on Aging Quiz (FAQI)

To determine the psychometric properties of an Iranian version of the Palmore's Questionnaire called Facts on Aging Quiz (FAQI). The psychometric properties including face validity, content validity, construct validity, internal consistency, and test- retest reliability were measured in 280 nurses who were working in the emergency, medical, and surgical wards of 5 randomly selected general hospitals associated with medical schools in Tehran. The results of known group's comparisons showed that this questionnaire could successfully discriminate between subgroups of nurses with different prior work experiences with the elderly and/ or had the experience of living with older people in the family. The internal consistency (Cronbach’s alpha) was 0.81. Test-retest reliability (ICC) of the questionnaire with interval time of two weeks was 0.98(P<0.001). Based on the results of the present study, the Farsi-version of FAQ 1 is a valid and reliable instrument for measuring nurses’ knowledge about older people. We concluded that the FAQI appears to be a promising tool, providing reliable and valid data helping to detect knowledge among nurses in different settings such as clinical settings, and research environments by health care providers and researchers.
